Jeep Gladiator electrical problems & fixes

Here are a few signs of electrical failure and their solutions;

1. The Engine Won’t Crank Properly

The engine requires electrical power to start. Through the ignition switch, the battery has to provide the spark through a spark plug that ignites the fuel in your engine. If your engine doesn’t crank properly, this could signify a bad battery, alternator, or another unrelated electrical problem.

The car’s alternator must work well with your battery to charge the vehicle’s electrical system. A bad alternator surely affects your car in many ways.

The most common issue is “clicking” when you turn the key and attempt to start your car. This means there is not enough current flow in the system to engage the engine. Usually, this is caused by a discharged or bad battery, but your starter could also be the source of the issue.

The starter motor should turn the engine over during ignition and allow everything else to happen. The starter motor allows the engine to suck air when the ignition is turned on.

If you hear a “grinding” noise during cranking, this could be because of a bad starter or a faulty flywheel ring gear. If these cases persist, then the electrical diagnosis is highly recommended. Scheduled maintenance is also advised to make your car stay in good condition.

2. You’re Experiencing Battery Problems

If you have issues with your battery, don’t just replace it without checking the car’s electrical systems. Most car batteries last about five years or less in hot climates. However, the issue could also lie with your alternator or somewhere else in the auto electrical system of your vehicle.

If you think your battery is at fault, check your battery cables for corrosion, and ensure they’re fitted properly because they mainly power the car’s electronic systems. If your car still doesn’t start, you can consider taking your battery to an auto shop to see if it is functioning properly.

If your battery is in good condition and is confirmed to be working properly, your issue likely lies elsewhere. Diagnosing your car’s electrical system is recommended so you can take your car to your nearest service station to have the alternator and other power systems checked.

Electrical repair specialists provide strategy-based solutions to these problems. If you don’t know how to diagnose and repair, get a jumpstart and a professional technician to check your vehicle’s electrical system and do the tedious auto electric repair.

3. Headlights and Other Lights Are Not Working Properly

Your car’s lights are one of the most important things that your electrical system controls. Turn signals, brake lights, and headlights keep you safe on the road, and interior illumination and lamps ensure you can see what you need to in dark conditions.

If your car’s electrical system is malfunctioning, you may notice that various lights start to dim. Dimming lights indicate charging malfunctions and low system voltage. The culprit could be a dying battery, loose wires, or a malfunctioning alternator belt.

If the check engine light of your dashboard lights, there is a minor or major issue with your car that needs auto electric repair. Check engine light is a malfunctioning indicator lamp signaled by the car’s engine computer telling that there is something wrong.

Corrosion of electrical systems may also be an issue. Unless you have a voltmeter handy and know how to use it, you probably won’t be able to do an electric diagnosis job yourself. However, if your car won’t start, it certainly has a car electrical issue, so take your car to a mechanic for full vehicle inspections.

4. Your Fuses Keep Blowing Out

Your car’s fuse box is designed to prevent overvoltage and short-circuiting. Fuses break the circuits, protecting vulnerable electrical systems from drawing too much current.

Occasionally, a fuse may blow for no real reason. In this case, simply replacing it is the only thing you need to do. But if you have a few fuses that blow out repeatedly, you likely have a deeper problem with your vehicle’s electrical systems.

An overheated and melted fuse disrupts electricity flowing. In some cases, a blown fuse is a symptom of a bigger problem to the electronic systems. Therefore, diagnostic and repair are highly recommended not to cause bigger problems.

Fuses protect your vehicle’s electric system. The fuse box will protect the high voltage produced by the battery and alternator. If you have to replace a fuse more than once in a short time, it is more likely to have electrical issues.

Get your car professionally examined and do auto electric repair. It’s likely there is an electrical fault or short-circuit causing the issue, which needs electrical repair, and if you don’t fix it, you could end up with further damage to your vehicle.

5. You Smell Burning Plastic Or Electrical Insulation

If you are experiencing any of the above problems and smell burning plastic or electrical insulation, you should stop driving your car immediately. This is a sure sign of an electrical malfunction or a short circuit, especially if it occurs alongside dimmed lights, blown fuses, and issues cranking or starting your car.

Get your car towed to the automotive electrical service station for diagnosis and repair. Avoid driving because you could further damage your vehicle, resulting in higher repair costs.

Jeep Gladiator battery problems & fixes

Here are a few symptoms that may indicate your Gladiator battery needs to be looked at by a Jeep mechanic or replaced.

  1. Delayed Engine Crank – when you attempt to start the vehicle, it takes longer than traditional to roll over or start.
  2. Check Engine Light – the check engine light usually turns on when your battery loses charge.
  3. Fluid Leaks or Corrosion – it’s natural for battery fluid and other fluid leaks to cause excessive corrosion, which is a distinct sign the battery needs to be replaced. However, over time, corrosion will build normally and can be cleaned to prolong the life of your   Jeep Gladiator battery.
  4. Low Battery Fluid Level – if the fluid level is low, you need to have the battery and charging system tested.

Testing your battery

The most common symptoms of bad Jeep Gladiator batteries are if your car is slow to start after turning the key or if your battery cables and connectors show signs of heavy corrosion.

You may also notice a clicking sound when turning the key or if your electronics work but the car won’t start. These are all tell-tale signs of failing batteries on your   Jeep Gladiator. So give our experts at Mike Shaw CDJR a call or book an online appointment here.

Jeep Gladiator Battery Replacement

Replacing some types of batteries, especially in newer models, can be tricky as vehicles’ hood space continues to shrink to improve performance. Because of this, some batteries can be difficult to access.

You’ll want to check your Jeep Gladiator owner’s manual for detailed information on where your battery is located. Oddly enough, some batteries can be located under the floorboard or in the trunk. However, this is extremely rare.

How to replace your battery:

  1. Ensure your engine is off – refer to your vehicle manual to locate the battery.
  2. Use a wrench to loosen the black negative battery cable bolt.
  3. Carefully remove the cable by twisting and pulling – do not use too much force or any metal objects to pry the cable away from the battery. This can damage the cable.
  4. Repeat steps 2 and 3 to remove the positive (red) battery cable.
  5. Locate the clamp that holds the battery in place and remove it with a wrench or ratchet.
  6. At this point, you should be able to remove the battery easily. But, be careful, it will be heavy.
  7. It is recommended that you clean the battery tray and any corrosion on the cables using a wire brush and a proper battery cleaning solution.
  8. To install the new battery, repeat the steps above.

Is it safe to drive with the battery light on?

The purpose of the alternator is to charge your Jeep Gladiator battery while you are driving. When the alternator isn’t running properly, it can cause the battery to drain all its power, leaving you stranded if the vehicle is turned off. Be confident in turning off the radio, air conditioner, and the lights unless you drive at night.

If your Gladiator battery warning light comes on while driving, be confident in turning off your accessories, so the battery doesn’t drain further. The warning light usually means that the alternator isn’t running properly, meaning you are operating solely on battery power.

It’s also probable that your Jeep Gladiator serpentine belt has malfunctioned. If you retain multiple warning lights, come on, including the battery light, then pull over to a safe location if probable.

If the dash lights imply overheating, the water pump was on that belt. Another feasible symptom that could point to the serpentine belt as a cause for the battery warning light is if the steering becomes difficult or feels hefty.

What Are the Best Car Batteries to Buy?

Popular car battery brands include DieHard Batteries, Odyssey, NAPA, AC Delco, Duralast, and EverStart. But, of course, many factors determine the “best” car battery, as many car batteries are designed with numerous factors in mind.

How long do Jeep Gladiator batteries last?

Jeep Gladiator batteries usually last between 3-5 years, but this is variable depending on weather conditions, driving habits, the type of battery, and more. You can prolong the life of your Gladiator battery by:

  • Starting your Jeep Gladiator continuously is intense. Don’t let your battery go unused for long periods.
  • Keeping the battery tightly fastened – did you know the vibrations of your car can loosen the connections and rattle your battery’s components?
  • Clean the terminals and posts of corrosion with the appropriate cleaning resolution & a wire brush.
  • Keeping your vehicle stored indoors away from extreme swings in temperature or climate

Just because your battery isn’t completely dead doesn’t mean it’s operating at optimal levels. Therefore, it is important to have your battery inspected every time you visit a service center.

If you leave your battery unchecked, your Jeep Gladiator can pressure the alternator or the starter to improve power when it’s not running at optimal levels.

Unfortunately, drawing excessive power to compensate for the loss of energy from the battery can make your engine run outside of ideal conditions. In the end, this will cost you more money to fix.

How often should you replace your Jeep Gladiator battery?

Every 3 to 5 years, you should have your battery frequently tested for voltage drops to ensure it’s operating at a high level. Car batteries typically carry 12 to 13 volts unless you have a high-performance battery. Anything higher than 13 volts may indicate a faulty battery.

Jeep Gladiator transmission problems & fixes

Common problems that often cause Jeep transmission problems:

  • Low transmission fluid level – Low transmission fluid level can cause several issues, including erratic shifting, no shifting, delayed shifting, strange grinding noises, limp mode, and even check engine light.
  • Faulty Torque Converter – Can cause Jeep transmission to slip in all gears, shuddering, and even overheating.
  • Worn Bands –  Can cause delayed shifting, shifting at high RPM, harsh shifting, no gear at all, no reverse.
  • Shifter Module – A faulty shifter module or shifter cable can cause the transmission to get stuck or not go in the selected gear.
  • Defective Valve Body – The valve body is very complex and can fail in several ways. Depending on the competence that fails, it can cause limp mode. In addition, the transmission may not shift at all or have harsh shifts between gear or specific gear.
  • Faulty Vehicle Speed Sensor  – If your Jeep has developed a harsh shift or is stuck in emergency mode (limp), the vehicle speed sensor (VSS) may be the problem. Sigan from the VSS is sent to the Powertrain Control Module (PCM), and the last signal can cause one or more of the previous systems.
  • Brake Light Switch – A faulty brake light switch can prevent the shifter from moving out or back in the park.
  • Low Battery Voltage – In rare cases, the low battery voltage can trigger the automatic transmission to get stuck in limp mode.
  • PCM / TCU / ECU Software Issue – Software issues can cause erratic shifting or downshifting issues. Transmission may shift too late, or gears to drop unexpectedly. This is a common problem for your particular transmission; a Jeep dealer may have a software update to fix such shifting problems.
  • Wire harness – Damages wire harnesses from ECU / PCM to the transmission housing can cause shifting problems. For example, you may not shift at all or go in gear.

Most Common Jeep Transmission Problems

Here is a list of the most common problems with Jeep transmission and possible causes.

Delayed or failed gear shifts

Older Jeep vehicles that use a 42RE or 42RLE 4-speed automatic transmission have a widespread issue with delayed or failed gear shifts. There are two different scenarios when this happens.

One is when shifting through 1st to 3rd gear, and the other is shifting from 3th to 4th gear. There will be no check engine light or other symptoms in most cases.

Possible causes

Worn or stuck governor pressure solenoid, preventing it from maintaining proper fluid pressure. This will affect 1st-3rd gear shifts. In addition, a faulty sensor or wiring issue will cause incorrect readings on the solenoid position.

Worn overdrive solenoid serves as a pressure accumulator that engages the overdrive gear. This will affect the 4th (overdrive) gear only. When this solenoid wears out, it cannot hold the transmission fluid pressure needed for proper operation.

Other possible causes include low transmission fluid levels or a dirty transmission filter.

Torque converter or overdrive issues

With a 42RE or 42RLE 4-speed automatic transmission made after 2000, Jeep can have sporadic torque converter clutch or overdrive engagement problems. Usually, this issue will trigger a ‘check engine’ warning light so that a corresponding code will be stored in ECU memory.

Possible causes

A broken cover plate holds the pressure boost valve in place on the bottom side of the valve body. This is a well-known problem, which is a result of poor design from the factory. As a result, the retaining bracket that holds the lockup pump breaks off. This triggers a P1740 code. Installing a special upgrade kit from Superior Solution is the best solution.

Faulty input/output speed sensors on the gearbox or faulty throttle position sensor. If any of them give the incorrect reading, it can affect torque converter clutch performance. These issues will usually trigger various speed sensor-related codes.

Faulty governor pressure solenoid or the corresponding sensor, as described.

Delayed or failed gear engagement

Jeeps that use a 545RFE 5-speed automatic transmission can develop gear engagement problems. This affects both drive and reverse gears and shows a noticeable delay with gear engagement when the vehicle is cold. The problem will be more apparent when outside temperatures are shallow. The check engine light may also come on.

Possible cause

Loose or disconnected transmission cooler filter. This allows the transmission fluid to drain from the torque converter when the vehicle is turned off for some time; it will delay gear engagement until the pressure builds up. Installing a modified filter solves the issue.

Dirty transmission fluid and filter, low fluid level, or improper transmission fluid

Delayed gear shifts or limp-home mode

Jeep vehicles with a Mercedes sourced 722.6 5-speed automatic transmission can suffer from issues that range from harsh and delayed gear shifts to gear slippage or even going into limp-home mode. These symptoms will be intermittent and trigger a check engine light to store a corresponding error code in most cases.

Possible causes

The faulty conductor plate holds the solenoids and connects them to the TCU. When the conductor plate is faulty, it causes communication problems, which results in improper solenoid operation. This is a well-known problem, and there are numerous aftermarket solutions.

Worn or faulty valve body solenoid. Sometimes, the problem can be due to damage to the internal wiring.  

Erratic gear shifts or gear slipping. 

Front-wheel drive Jeeps with an A6MF1 6-speed automatic transmission can develop issues with incorrect gear changes. Shifts can be erratic, or there can even be a slippage during gear shifts. In most cases, the symptoms will be more noticeable when cold. In addition, there might be a check engine light and corresponding codes in DTC memory.

Possible causes

Leaking or sticking solenoids that engage each gear. This is a gradual process that starts only when cold and worsens with time. The only solution is replacing the whole solenoid set with new or upgraded ones.

Faulty or damaged solenoid wiring obstructs signals from the TCU. Checking and repairing or replacing the wiring will solve the issue.

Intermittent shifts to neutral

Front-wheel drive Jeeps with a ZF9HP48 9-speed automatic transmission can unexpectedly shift to neutral while driving. This issue is intermittent in most cases, and there will be no apparent correlation to driving conditions or overheating. However, this problem will trigger a check engine light, and a corresponding DTC code will be stored in the Engine Control Unit (ECU).

Possible cause

Faulty transaxle range sensor connector and wiring, which causes incorrect signals from the sensor. When the TCU detects an implausible signal, it shifts the transmission to neutral and sets the P0901 code. As this is a well-known problem and a serious safety issue, a Service Bulletin covers it. Check if your vehicle is affected.

Troubleshooting Jeep Transmission Problems

Follow the steps to troubleshoot and isolate Jeep transmission problems. It is critical to determine which transmission is installed on your Jeep to research the issues affecting that transmission. You can verify the transfer by Decoding your VIN or calling the dealer.

The next step is to check the transmission fluid level. Low transmission fluid level is one of the most common issues that cause shifting issues on Jeep Wrangler, Gand Cherokee, Renegade, Compass, Gladiator, and Cherokee.

How to Check Jeep Transmission Fluid Level

This procedure should only be performed to check the transmission fluid that may be slightly low. If the transmission fluid is extremely low, you need to add fluid and check the level. Checking the transmission fluid level on a transmission with no fluid can damage the transmission.

  • Park the vehicle on level ground when possible.
  • Set the parking brakes and shifter in the park.
  • Pull the hood release and open the hood.
  • Locate the transmission dipstick.
  • Remove the dipstick and clean it with a clean cloth.
  • Reinsert the dipstick in the transmission. Ensure the transmission is fully inserted, then remove it.
  • Look carefully at the dipstick to determine the current transmission fluid level. The level should be between MIN and MAX marks for the COLD (lower) markings.
  • If the level is low, add transmission fluid level.
  • Drive the vehicle for fifteen minutes to select all the gears manually.
  • Repeat the procedure once the transmission warm-up, but this time, the level must be between the MIN and MAX marks for the HOD (higher) markings.

Note: Not all Jeep vehicles have a transmission dipstick. If the dipstick is not present, the vehicle will need to be raised on a lift, and the level can be checked via the fill hole.

Reset Automatic Transmission Adaptation

Adaptive automatic transmission monitors your driving behavior and adjusts the gear shits to deliver the driver’s best engine response and shift points. If you have a newer Jeep, it is highly likely to monitor your driving behavior.

Resetting the transmission adaptation to the factory setting can make your Jeep shift normal again. This simple procedure can improve shifting and does not cause adverse effects.

This procedure will work on W5A580 transmission but may work on other models. It does not cause any problems and doesn’t hurt to try.

Here is how to reset the Jeep transmission without any tools:

  • Press the gas pedal down and keep it pressed.
  • Turn ignition on without starting the engine.
  • Keep ignition on (engine off), and the gas pedal pressed for thirty seconds.
  • Turn the ignition off.
  • Release the gas pedal.
  • Start the engine, and don’t drive too aggressively for the next twenty miles. If the procedure above does not improve the shift quality, you can perform a transmission adaption reset with a professional scanner.

How to Read Transmission Fault Codes

If the transmission fluid level is correct, the next step is to read fault codes from the transmission control module or what is known as the TCU. To retrieve transmission codes, you will need a Jeep OBD-II Scanner. Basic code readers are not recommended because they can only read codes from the Engine Control Unit and not Transmission Control Unit.

  • Park the vehicle and turn off the ignition—set parking brakes.
  • Locate the diagnostic port under the dashboard, driver’s side.
  • Plugin your OBD-II scanner and turn on the ignition without starting the engine.
  • The scanner will turn on. Allow it to communicate with the vehicle. Select MAKINA; then, your particular model.
  • Select Control Units, then Transmission.
  • Select Read Fault Codes from the main menu. 

Jeep Gladiator Transmission won’t go into park

There could be many reasons why your Jeep Gladiator transmission doesn’t go into park. The most common reasons are:

  • Shift lock solenoid – The shift lock solenoid is the mechanism that stops the Jeep Gladiator from being able to be shifted out of park when the vehicle is off. It also won’t let you put your vehicle into drive without turning on your ignition and putting your foot on the brake.
  • Ignition barrel – the ignition barrel generally makes it hard to get the transmission out of park, but an ignition barrel/tumbler can make it difficult to get into park as well
  • Faulty shifter mechanism – If the shifter mechanism has a lot of play, it can make it difficult to shift
  • Faulty shifter cable – Generally, automatic transmissions have a single cable connected to the transmission. If it has been damaged or has broken, it can prevent the gears from engaging properly
  • Failing transmission – an internal issue inside the transmission could also cause the transmission not to shift properly

Here are a couple of ways to tell if your transmission is starting to develop an issue:-

The Jeep Gladiator’s shifter has excessive movement

The transmission can be diagnosed at your local workshop, and depending on the issue, it will depend on what repair will be carried out. This can vary from a simple shifter bushes replacement to a complete transmission overhaul or replacement.

Suppose you don’t get your Jeep Gladiator transmission repaired when it starts to have problems. You can get caught out. Generally, if you can’t put your vehicle into the park, you can’t take the key out of the ignition, which means you won’t be able to lock it, and you’ll be up for a tow to your local workshop.

Why is my Jeep Gladiator not starting?

Jeep Gladiator is a reliable road companion, but it’s a machine with hundreds of interconnected parts, and like any other machine, it sometimes fails to deliver normal operation.

The most common causes include;

1. Weak Battery

If your Gladiator’s engine won’t crank very slowly, then the most likely culprit is a weak or dead 12v battery. However, investigating more closely and doing a battery voltage test will clarify whether the starting problem is due to the battery. A test can be done to measure the voltage between the battery poles, check the acid level, and assess the condition of the starter battery.

If a new car battery has been installed, the battery may not have yet reached its full capacity. However, there is nothing to worry about. A new battery only develops its full capacity over time.

Test 12v battery

The battery’s voltage on your Jeep Gladiator can be measured precisely with a multimeter. Before the test, the multimeter should be set to the voltage range of the battery and connected to its plus and minus poles.

Successful testing of the car battery, i.e., checking the voltage, usually results in approximately—12 to 13 volts. Values ​​above 14 or below 11.5 volts require an expert assessment of the car battery’s condition because the battery may have a defect with these measured values ​​and must be replaced.

Jumpstart Jeep Gladiator

Suppose a dead battery is a reason for the breakdown of your Gladiator. Then, you can easily jump-start it using jumper cables and a healthy battery from another vehicle or using a battery booster if available.

First, connect the red cable to the positive terminal of your Gladiator’s dead battery, then to the positive terminal of the donor battery. Next, connect the black cable to the negative terminal of the donor battery, then to the bare metal in the engine bay of your Gladiator. Start the donor vehicle and then your Gladiator. Remove the cables in reverse order.

2. Corrosion on battery

Corrosion on the contacts of your car battery leads to loss of contact and reduced current flow, which means that your engine can no longer start properly. To know if your Gladiator’s starting problems are from dirty battery contacts, you need to investigate them.

If you lift the rubber covers over the two battery terminals, you can check the terminals for corrosion. If you discover white or silvery-green deposits but no further cracks or damage, you do not have to replace the battery; clean it.

Clean battery corrosion

To clean the battery on your Jeep Gladiator, you have to remove the pole cables first, which requires no special knowledge, just a little concentration, as the order is very important. First, remove the black cable from the negative pole. If the pole clamp is very tight, you can open it with pliers.

Do not use metal pliers, but if you use them, you must make sure that you do not touch any other body parts. Next, you can unplug the red positive pole cable. Once the battery has been removed from the circuit, you can start cleaning the corroded battery. After cleaning, reconnect the terminals.

3. Weak key fob battery

If your Gladiator has a push start/stop button, then it is possible that your vehicle may not start due to a weak key fob battery. Don’t worry. You can still start your vehicle. The battery is only used to send the signal for locking/unlocking. If the key fob battery is empty, the door no longer locks or unlocks at the push of a button.

The doors must then be opened manually. A passive transponder controls the immobilizer. Passive means, among other things, that the transponder in the key does not need its power source.

How to start Jeep Gladiator with a dead key fob battery

If you have a model of Gladiator that only has a key fob with a start/stop button and no place to insert a key, try placing your key fob as close to the start/stop button as you can and then start the vehicle.

Note: You can try starting your Gladiator with its second key. It will also rule out any other problem with the first key, for example, water damage.

4. Broken starter motor

A starter is a motor for starting the engine of your Gladiator. The average life of a starter motor is about 100,000 to 150,000 miles, and the life will be shortened if the engine is started more frequently. Since the starter motor also has a limited life, it will break down after using the car for a long time, and if the starter motor breaks down, the engine will not start.

Symptom: When you turn the key to start the engine of your Gladiator, you will hear a clicking sound, which is the sound of a bad starter motor. And if the starter motor does not work with a healthy battery, suspect a malfunction of the starter.

If the starter fails, it usually needs to be replaced with a new one.

Temporary fix for starter

If the engine does not start due to the starter, the engine may start if you turn the key while hitting the starter motor with something like a stick or metal tool. This workaround is effective when the parts inside the starter are stuck together, or the gears are slightly out of alignment.

However, the starter may be nearing the end of its life, so it is recommended that you have it inspected at a dealer or maintenance shop.

5. Defective alternator

An alternator is a generator that produces electricity. If your Gladiator’s alternator fails, it will not produce electricity, and the battery will not be able to charge. Therefore, even if you think that the cause of the engine not starting is a battery failure and replacing the battery, the battery will soon run out, and the engine will not start.

Alternators rarely break down. In particular, modern cars have improved performance, so it is said that they will last 200,000 to 300,000 miles. Still, it can break down depending on how you use it, and in the case of a used car, the alternator may be quite old. So don’t let your guard down.

If the alternator breaks down, it must be replaced with a new alternator.

6. Clogged fuel filter

The fuel filter of your Gladiator does not wear out like a mechanical part, but it gets clogged by dirt and airborne particles and clogs over time. The permeability of the filter drops, and so does the fuel pressure. To a certain extent, this doesn’t matter, but if the fuel filter is too dirty, the engine will no longer perform at full capacity and, in some instances, may not start at all. Cleaning is not possible. You can only change the filter.

7. Fuel pump failure

If your Gladiator’s fuel pump fails, the engine won’t start. The pump normally ensures that the necessary amount of fuel is passed from the tank to the engine’s injection system with sufficient pressure.

Before your fuel pump stops working, it usually becomes noticeable: if your car’s engine breaks down from time to time, the car is difficult to start, the engine jerks a little, or the engine performance drops, you should have your pump checked.

Wear or contamination of the pump can be the reason for this. If the pump is leaking, a power contact is broken, a line or a pump lever is broken, the fuel pump is usually noticeable before failure. You can have a defective fuel pump replaced in your workshop.

8. Blown fuse

In rare cases, a blown a fuse could also be the culprit in the breakdown of your Gladiator. So, check all fuses essential for starting the engine in the fuse box. But, be careful when lending a hand yourself to the fuse box! The box is under power, and repairs or tests should always be done in a workshop.

9. Defective spark plugs

Without functioning spark plugs, the engine will not start. The spark plugs themselves are often not affected by a defect. Instead, plug connections on the ignition system come loose. If only one plug is loose, you can fix the problem yourself on site. If a spark plug has failed, it must be replaced in the workshop.

10. Rodent damage

Rodent damage can be another reason why your Jeep Gladiator won’t start. The animals crawl under the vehicle and bite through cables and wires. In principle, this can affect all vehicle systems, such as fuel, oil, or power supply.

The rodent damage can usually be seen quickly by looking into the engine compartment. The damage caused by the rodent bite can be repaired in the workshop. Be prepared for relatively high costs here.

11. Engine failure

Although very rare, it can also cause the breakdown of your Gladiator. If a vehicle has an engine failure, then nothing works anymore. It is not uncommon for the vehicle driver to be responsible for such damage.

Typical causes include tearing of the timing belt, incorrect fueling, insufficient oil, hydrolock, overheating of the engine, or continuous driving in an excessive speed range. Only an experienced mechanic can diagnose engine failure in a workshop.

How to Use OBD2 scanner for diagnosis

Since Jeep Gladiator is equipped with onboard diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located. However, you must first connect the diagnostic tool to your Gladiator to begin troubleshooting.

The OBDII connector is usually located under the dashboard. With the wire connected, you should turn on the ignition. But be careful not to start the engine. Most diagnostic devices then ask for some information about the vehicle.

It is important that you enter this 100% correctly. Otherwise, the result of the search may be falsified. In addition to the vehicle manufacturer and model, you usually also have to type in the engine and vehicle ID number. For accurate troubleshooting, always check whether the information is correct.

Jeep Gladiator remote start not working

Your remote starter system’s battery may need to be replaced if it’s not functioning correctly. Batteries Plus sells replacement key fob batteries. A lithium coin cell battery is most commonly used for remote starter fobs.

If, however, your remote starter does not work after this, you can try the solutions below. If it still doesn’t work after that, replace the key fob.

How to Reprogram your Jeep Gladiator Car Remote

  • Replace the batteries that are inside key fobs.
  • The best way to find out is to get inside the car.
  • Turn on the ignition key.
  • The remote key can be used to lock your computer. Press the lock button.
  • There is an app for checking for Lock Sounds.
  • Additional remotes to be programmed.
  • Turn off the engine and wait a few moments.
  • Your automobile should be turned over to you so you can test it.

How to resync the key fob

  • Start your car by turning the ignition switch on.
  • The second step is to press the lock button.
  • The third step involves turning off the ignition.
  • Repeating the process with all other key chains.

How Do I Reset My Car Remote?

You can turn on your car’s ignition by pressing and holding the “lock” button for one second on its remote. Turning the key “Off” dims the lights.

How to reset a Jeep Gladiator radio

Over the years, Jeep Wrangler owners have experienced problems with their radios. In older systems, this includes things like the radio sound skipping and, in some cases, not switching on altogether.

These problems can be traced to several possible causes ranging from blown fuses, software problems, or unstable connections. Finally, we will show you a few methods of resetting your radio and possibly fixing the problem.

Let’s take a look at some of these methods now;

Method 1

  • Turn ignition to ON

  • The radio will reboot and reset

In some instances, the problem needs you to remove the radio from the dash and physically reset a chip inside the radio itself. This is a more complex approach and will require you to have some basic DIY skills.

Removing the radio involves removing the whole dash panel first from your Jeep. This process needs you to know what you are doing. Otherwise, you will end up causing more harm than good to your Jeep and radio.

How to reset the Uconnect on a Jeep Gladiator

If your Jeep has a newer UConnect system, the reset method will be slightly different. However, you can use method two if the other methods we will describe don’t work.

The methods will vary depending on the UConnect system and firmware you are running. When it comes to the UConnect system, the problems you experience will vary.

They range from software issues to physical damage, so you will need to understand the nature of the problem before attempting to fix it.

Method 1

  • Press the upper right corner of your UConnect screen until the screen shows your vehicle logo
  • The screen will go dark for a couple of seconds
  • The screen will then show your vehicle logo again

They should resolve any issues with Bluetooth® connection, navigation, and small mishaps with the Uconnect® system without requiring you to entirely wipe the system of all the settings you’ve enabled thus far.

Jeep Gladiator Check Engine Light

When your Jeep Gladiator’s ECM (electronic control module), which is the vehicle’s onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light.

This amber or yellow light is typically labeled “check engine” or “service engine soon,” or the light may be nothing more than a picture of an engine or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies the issue, whether it’s a sensor or a failing engine part. So when your check engine light comes on, this could be as simple as tightening or replacing your gas cap. However, the check engine light could also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty repair bill.

Here are some potential reasons why your car’s check engine light is on;

Missing, damaged, or Loose gas cap

One of the most normal and many causes is that your   Jeep Gladiator gas cap is loose, damaged, or missing. The gas cap for your   Jeep Gladiator serves multiple purposes. First, it prevents gas fumes from being released when you aren’t driving. It seals the fuel system and helps maintain pressure within the fuel tank.

If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, replacing a gas cap isn’t expensive. However, if your check engine light turns on suddenly after you put gas in your   Jeep Gladiator, you should check to make sure the cap isn’t loose — or that it’s still on your car’s roof or at the fuel pump.

Damaged sensors

Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, acknowledged as the O2 sensor measures oxygen payment in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster, and your vehicle will be less adequate when it comes to fuel economy.

Note: A faulty sensor can not only affect your miles per gallon, but it can cause wear and tear to your catalytic converter and your   Jeep Gladiator’s spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for the modest mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.

Vacuum leak

Every Jeep Gladiator has a vacuum system that performs various functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack hugely if exposed to agitated heat or extreme cold.

A dead or weak battery

The battery is poor or dead. The battery in your Jeep Gladiator is very important. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did various decades ago, and they don’t require maintenance. But, of course, the price of a new one depends on the type of Jeep you drive.

Use of generic parts

Issues with any aftermarket items. An aftermarket alarm, exhaust, or added item can wreak havoc on your Jeep Gladiator if not installed perfectly. These aftermarket parts and accessories can discard the battery, trigger the check engine light, or even hinder the vehicle from starting.

If these issues sound commonplace, bring your Gladiator to Jeep and have our company of certified mechanics ensure that your aftermarket items were installed well and aren’t causing any issues.

Getting accessories, hugely aftermarket parts, and accessories, or using OEM parts first place might price slightly more. Still, it could save you money from getting shoddy work and wear and tear caused by poor installation work corrected.

Damaged Spark Plugs or Plug Wires

The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires bring the spark from the ignition coil to the spark plugs.

If your spark plugs or spark plug wires are bad or old, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or running. In addition, worn spark plugs and plug wires can cause clogged catalytic converters or wear and tear to ignition coils and O2 sensors, best to more expensive repairs.

Faulty mass airflow sensor (MAF)

The mass airflow sensor in your Jeep Gladiator determines how much fuel is essential to run your engine efficiently by measuring the payment of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to amiable changes, like altitude. If your Jeep Gladiator is having trouble starting, idling rough, or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.

Faulty catalytic converter

The catalytic converter’s function is to turn the carbon monoxide created by the combustion process into carbon dioxide. Therefore, a damaged catalytic converter is usually caused by neglected maintenance.

Suppose you have an issue with your catalytic converter and don’t get it repaired. In that case, your   Jeep Gladiator will not pass an emissions test, show a lack of engine performance, and negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause added problems from overheating.

Is it safe to drive your Jeep Gladiator with the check engine light on?

This question is not extremely available because it all depends on the severity of the issue. If the cause is a minor issue, such as a loose gas cap, it should be safe to travel to work. This is commonly indicated by a steady glow of the check engine light.

If you notice a variation in the automobile’s performance, it could be an indication of a more terrible problem. For example, if the check engine light is flashing, there is a terrible issue, and it is recommended to service your Jeep Gladiator promptly.

Can the check engine light reset itself?

The check engine light on your   Jeep Gladiator will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it’s tightened, the light will turn itself off.

Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your Jeep Gladiator light will go off after about 20-40 miles.

If you drive over that amount and the light is still on, take your car to a mechanic so the light and code can be double-checked and reset.

Jeep Gladiator auto start-stop is not working

Here are some reasons why your Jeep Gladiator is not w9rking;

There is an issue with the battery.

Start-stop systems need a special battery to run inside a car’s engine. A special battery allows these start-stop systems to turn off and turn on again and stay idle constantly. A regular battery can’t do this.

If you notice your start-stop system isn’t working, check if your check engine light is flashing on and off. If it is, you have to go to the mechanic and get your battery diagnosed. You may be able to drive your vehicle without a functioning start-stop system. However, the fuel efficiency won’t be as good.

The weather is too cold.

This was funny when I learned about it because most people don’t want to work in cold weather. Now the systems in our vehicles don’t want to either! You need to give your vehicle enough time to warm up in cold weather. If you don’t, the start-stop system will not activate until the engine is at the right temperature.

You need to wait and let your car warm up until your computer dashboard signals that your start-stop system is ready. Then, you can drive your car if the weather is too cold for the start-stop system to activate. However, your car will produce higher emissions. It also won’t perform as well with its fuel efficiency.

You placed your car in a position, and the computer’s start-stop system will not function while in that position. Having your wheels turned at a sharp angle will override the start-stop system in certain car models, and your engine will not turn off. This is based on what the computer system expects the driver to do.

A car with its wheel placed in a hard angular turn will need to propel quickly to make a turn. In this case, the start-stop system won’t activate, so the car to pick up speed quickly

There’s nothing you can do to change the start-stop system in these situations. It is built into the computer system. However, if you experiment, you can find the perfect angle degree turn. The wheels of your vehicle should be in the direction you want to turn, but your system will stay active.

You have your AC or heater on inside the vehicle at full blast.

Modern cars may be creations of engineering genius, but they’re not perfect. Every computer system does its best to preserve the battery. So if you’re using the AC or the heater at full blast, it takes a lot of energy from the battery. The start-stop system won’t activate. There’s just not enough charge in the battery to fuel all these different functions.

However, if you reduce the power of your heater or AC, then the system will activate. So it’s all about giving and taking. But, hey, that reminds me of my wedding night!

Your battery isn’t fully charged.

Yes, you read that correctly, and I can’t say I’m not a little disappointed. The start-stop system seems like a great way to save money at the gas station and reduce enough smog going into the air.

But all these great advantages won’t appear unless my car is 100% fully charged? That’s a bummer, especially since I can’t always charge my hybrid vehicle.

In this situation, the only thing you can do is constantly keep your hybrid car charged up. Do this as much to take advantage of the benefits of the start-stop system in your car.

Jeep Gladiator backup camera not working

You will need to troubleshoot the cause of the issue before you can repair your backup camera.

Items needed;

  • Voltmeter
  • Socket wrenches
  • Screwdrivers (Phillips and flathead)
  • Wirecutter and stripper
  • Replacement fuses
  • Maintenance manual for your model of Jeep

Drain the Battery and Do a Reset

Many users online report that Jeep wireless firmware updates to your backup camera can sometimes cause errors. Unfortunately, one of the best ways to do a flash reset is by draining the battery.

Here are the steps to drain the battery on many Jeep models and do that reset:

  • Open the hood and disconnect the positive battery terminal. Next, touch it to a ground (electrical, not the physical ground) for 30 seconds. This will discharge the capacitors that keep the memory working in your Jeep.
  • Reconnect the battery cable.
  • Turn the ignition switch to the “ON” position but don’t start the engine yet.
  • Turn the headlights on and off.
  • Turn the ignition off, then start the engine.

If this doesn’t cause your camera to re-engage properly, try some of the steps below.

Check Your Connections and Circuits

A good next step is to start checking the different connections and circuits. It might be as simple as a burnt-out fuse, which you can usually determine after a quick look inside the fuse box. But, if that’s not the case, you can probably start checking for ineffective circuits in any one of these areas:

Inspect the Camera Ground Circuit

Check for loose or damaged wiring connections at the camera itself, the light bar on the vehicle’s rear, and the liftgate. See if there are problems with your voltmeter, and repair the ground circuit.

Problem with the Camera Feed/Run Relay Circuit

Check for loose or damaged wiring connections at the camera, light bar, and upper liftgate.

Non-functional Camera Return Circuit

Check for loose or damaged wiring connections at the right cowl side inner panel and your radio.

Bad Camera Signal Circuit

Similar to the camera return circuit, but a separate connection to check. These are just some of the possible connections with a bad circuit to check. Once you’ve checked all of the above, check every circuit to be sure.

Short Circuits

A short circuit is when an electrical current is allowed to travel along an unintended path, which can create all sorts of problems for your vehicle’s electrical system. Of course, it’s unlikely that a short circuit is causing your problems, but here is a helpful video on diagnosing short circuits and determining if that’s your problem.

If you’re having a wiring or lighting problem, the culprit is often a blown or bad fuse. So first, pop opens the fuse box on your Jeep. There might be one or two of them on your model, but they are usually located on the right kick panel and under the Jeep’s hood.

Installing a fuse is easy: Pull the old one out, and replace it with one of the right types. Then, if your problem goes away, you’re good to go. However, if fuses keep blowing or the problem persists, you might have a short-circuit, which might necessitate a visit to the mechanic.

Diagnostic Tool

For the very serious DIY-er, a diagnostic tool is a powerful necessity for troubleshooting most modern vehicles, your Jeep included. Usually, a mechanic will plug into your vehicle’s adapter to run diagnostic tests, and most repair shops will have a huge supply of these adapters for different vehicles.

Unfortunately, the connectors and adapters required for these tools and the requisite software required to use them can be expensive for at-home repairs. Here’s a link to get you started with JScan, one of the options for Jeep diagnostics.

Bad Camera Troubleshooting

Backup cameras are often exposed to some pretty harsh conditions, which means they’re usually durable. However, just like any other piece of equipment, damage can happen. Simple tests you can do:

With the help of a friend at the wheel or the bumper, wiggle around or flick your backup camera while the camera should be engaged. If it comes back on or gives a momentary flicker, it probably means you need a new camera.

You can also disconnect the camera and check and see if any moisture or condensation has gotten inside it. If this is the case, the camera might be beyond repair, but you can always attempt the tried-and-true method of immersing it in a desiccant like rice to see if that solves the problem.

Jeep Gladiator is not going into gear

Here are the most common reasons why your car won’t go into gear;

Low Transmission Fluid

The car won’t go into gear because the level of transmission fluid in the vehicle is lower than required. There may be a leak if the level is low despite regular maintenance. Transmission fluid, therefore, is important to ensure that the car’s moving parts are properly lubricated for functioning.

Automatic Transmission: Malfunctioning Shift Lock Release

To prevent the car from being accidentally put into gear without a driver present, modern cars with automatic transmissions will lock the shift knob in the park until the driver’s foot is on the brake and the engine has been started. In some cases, the shift lock could get stuck and fail to disengage properly.

All modern cars with automatic shifters have a Shift Lock or Shift Lock Release switch somewhere near the shifter. Often, it’s hidden under a small trim piece that you’ll need to remove with a small screwdriver or key. It’s operated by sticking the key in to release the lock. You’ll then be able to shift into drive.

Manual Transmission: Failed Clutch Master Cylinder

In a stick-shift car, the master cylinder is responsible for translating the motion of the clutch pedal into motion that releases and engages the clutch itself in the transmission. The master cylinder operates using hydraulic fluid. Over time, the clutch master cylinder could spring a small leak.

Once enough fluid has leaked out of the system, the clutch pedal will stop engaging the clutch, and the car won’t go in gear. Another symptom of this problem is a clutch pedal that falls to the floor. You’ll want to have a professional technician replace your clutch master cylinder to address this issue.

Automatic Transmission: Bad Automatic Transmission Fluid

A modern automatic transmission operates on the principle of fluid dynamics. Over time, the transmission fluid will thin out, become dirty and require replacement — otherwise, the car might struggle to go into gear.

You might also experience rough shifts, or the car might require multiple attempts to go into reverse or go from reverse into drive. That’s why it’s important to have clean automatic transmission fluid in your car and replace it according to the recommendation in your owner’s manual.

Severed Linkage Wire

Of course, if the shift knob in the cabin can’t actually “talk to” the transmission located underneath the car, it’s not going to be able to go into gear. While an uncommon problem, cables and wires can occasionally be severed over time by rubbing against sharp metal edges on the car’s frame.

If the linkage cable to your clutch or transmission is pinched off or severed, you won’t be able to get your car into gear — regardless of what you do or what kind of transmission your ride is equipped with.

If you’ve exhausted all your other options and you suspect a severed linkage cable, you’ll want to have a trained technician take a closer look. Locating the source of this problem can be especially tricky and requires advanced tools.

Bad Torque Converter

Many internal components may go bad and prevent gear from shifting in automatic transmissions. For example, components like a pump, stator, and turbine in a torque converter can become faulty and cause slipping when the transmission shifts gears.

Therefore, it is important to inspect these elements as they can block the transmission from shifting altogether. Regular automatic transmission maintenance can also help resolve minor problems that prevent your car from shifting gears properly.

How long is the bed of a Jeep Gladiator?

The new Jeep Gladiator’s bed is 60.3 inches long and 56.8 inches wide. The area between the wheel wells extends 44.8 inches. These specs apply to the 2020 and 2021 Gladiator.

How to take the soft top off a Jeep Gladiator

  • To get to your header latches, you’ll need to unclip your sun visors.
  • Then, click open the header latches. Some older models may also have clip retainers above the front and rear doors that must be unlatched.
  • The front of your top is on a hinge. Fold back the top, careful to keep your fingers out of the way.
  • You’ll want to pull the fabric back to keep it from being crushed in the folding bars. Then, velcro these bars together for added security.
  • Open the swing gate on the rear of your Jeep Wrangler and begin unzipping the back window from the right-hand side.
  • Next, roll out the bottom retainer bar by tilting it up and pulling it out.
  • Next, you’ll be removing the rear sail panel retainers, which are the vertical pieces covering the rear corners.
  • Untuck these pieces and fold them up and over the roof of your Jeep.
  • To remove the quarter windows, lift the Velcro on both the back windows’ top and rear side.
  • Open the rear door, and undo the zipper. Remove the retainer rails.
  • Now you can fully remove the top. Find the latch on the bars just above the front of the rear windows.
  • Press down on the latch and slide the top back on the railing until it folds over. Then, you can rest the U-shaped frame around the back of your Jeep while you Velcro the bars together.

How to Install the Soft Top on Your Jeep Wrangler

  • Remove the Velcro straps from the side bows at the back of your Jeep Wrangler, and open the tailgate.
  • Lift the soft top and drop the sidebar onto the rail, sliding it forward until the latch clicks.
  • Fold the header over toward the windshield.
  • Reach inside the front doors to loosely fasten the latches under the sun visors. You’ll tighten these latches later.
  • Fold down the sail panels and hook them into the rail above the taillights.
  • Slide the tailgate bar through the back window strip, ensuring the rubber seal is on the bottom outside.
  • Roll the tailgate bar into place on the clips above the taillights and zip the window closed. Then close the tailgate.
  • Open the rear doors to have easier access to installing the rear quarter windows.
  • Use the Velcro to help hold the windows in place as you zip them on a few inches and tuck in the retainers.
  • Finish zipping the windows.
  • Secure the header windshield latches.

How to open a Jeep Gladiator hood

  • Undo the latches on both sides of the hood. You’re looking for the large latches towards the front sides of the hood, right above the headlights.
  • Run your fingers beneath the edge, directly above the Jeep logo. You’re looking for the hood release latch.
  • Once you find this, nudge the latch to the left to release the hood.
  • Gently raise the hood by pushing it up at the edges.
  • Lower the hood stand folded underneath the hood. This will be the pole you’ll see as you lift the hood.
  • As you lower the hood stand, secure it in the hole at the front of the vehicle. This will keep the hood propped open so you can easily work on the engine without any difficulty.

How much oil does a Jeep Gladiator hold?

The amount of oil depends greatly on the type of vehicle, engine size, and type of oil. For example, 4-cylinder passenger cars take less oil and typically use conventional oil compared to a vehicle with a high-performance V-8 engine, which may require full synthetic motor oil.

Most engines require anywhere between 5 to 8 quarts of oil. So, for example, a 4-cylinder engine will require at least 5 quarts of oil, and a 6-cylinder engine will require around 6 quarts of motor oil.

The oil, coolant, and fuel capacity for this version of Jeep Gladiator Sport 3.6 V6 6-speed are as follows:

Engine lubricant oil capacity:

  • 5.4 liter / 5.7 U.S. qt / 4.8 imp. qt
  • Engine coolant capacity:
  • 10.1 liter / 10.7 U.S. qt / 8.9 imp. qt
  • Fuel tank capacity:
  • 83 liter / 21.9 U.S. gal / 18.2 imp. Gal

Jeep Gladiator Oil Change

An oil change is one of the most extensive and imposing services for your car. Jeep recommends changing your Jeep Gladiator oil and filter every 3,000-5,000 miles for conventional oil.

Check this too: Honda Ridgeline Emissions Systems Problems Overview

Synthetic oil ordinarily should be changed every 7,500 – 10,000 miles. Keep in mind it’s best to check your owner’s manual and with your dealer to find out the intervals that work best for your vehicle.

What happens if you don’t change the oil?

Here are some reasons why you need to change your Jeep gladiator’s oil as recommended;

  • Keeps the Jeep Gladiator engine clean – This is vital to keep the engine running at maximum efficiency. The oil picks up debris and dust particles and carries them to the oil filter, where they become trapped. This reduces the risk of dirt building up in the engine and causing damage to the engine.
  • To help improve fuel efficiency, the slipperier the engine components, the less force required to move them, so the engine uses less fuel.
  • Helps to lower heat – aside from the explosions caused by the spark plug and gasoline, heat is produced from the friction of engine components, and the excessive heat can cause real damage to vital engine components. In addition, as oil moves around, the engine heat is carried away to cooler components. This heat dissipation means that no one area of the engine should become too hot.
  • Prevents engine knocking – since components, like your engine pistons, don’t touch, the oil provides lubrication and prevents the components from touching. This helps prevents problems and damage caused by engine knocking.
  • Protects the engine components from corrosion – One of the additives ongoing within the majority of oils is to help lower oxidation and prevent corrosion.

Jeep Gladiator Steering Problems

Steering problems accounted for 110 out of 147 (75%) complaints against the 2020 Jeep Gladiator registered with the National Highway Traffic Safety Administration (NHTSA). Specifically, gladiator owners report that the steering is dangerously loose, especially at highway speeds and warmer weather, and requires constant correction.

Some owners describe the steering problems as:

  • Loose steering
  • Wandering
  • Drifting
  • Excessive playing
  • Pulling to the left or right

Has the issue been resolved?

While the auto manufacturer has acknowledged the problem, it has yet to be fixed or part of a recall. In August 2020, Jeep released a Technical Service Bulletin (TSB) addressing the Gladiator’s “pull” and “excessive play” steering issues.

The TSB is not the same thing as a recall. A recall is issued when a vehicle defect breaches safety standards or affects something safety-related to the vehicle; additionally, the car manufacturer is responsible for fixing all affected vehicles without expensing the consumer.

On the other hand, a TSB is issued when a technical problem with a vehicle is not (yet proven) a safety concern. The manufacturer tells owners how to repair the problem with a TSB but is not responsible for paying for repairs. Either cost will come out of the consumer’s pocket or be covered under the car’s warranty.

Note: There are no complaints of steering issues for the 2021 Jeep Gladiator yet.
