Engine And Engine Cooling Problems of Jeep Wrangler - part 1

Absolutely terrible gasoline vapor filling the inside cabin of the vehicle causing burning eyes, nausea and feeing ill. Checked for fuel, leak, leakage recall, while there was one it wasn’t including our VIN, however, after inspection and repair, it is the exact same damage as what was indicated in the recall. Looking for a full refund for repair and compensation for danger, discomfort, safety and inconvenience of vehicle not being included in the original recall. I am appalled and insulted that Jeep dealerships aren’t more more proactive in having to appeal these dangerous situations.

The contact owns a 2021 Jeep Wrangler. The contact stated that while operating the vehicle, the engine overheated, and the vehicle was driving sluggishly with the temperature gauge indicating that the engine was overheating. The vehicle was taken to an independent mechanic who determined that the coolant reservoir was cracked and was leaking coolant. The coolant reservoir was replaced, and the vehicle was repaired. The contact stated that the vehicle failed to immediately start due to battery failure. No further information was available. The local dealer was notified of the failures, but no assistance was provided. The failure mileage was 56,700.

I am reporting repeated premature failures of the factory charge air cooler (turbo intercooler) hoses on my 2022 Jeep Wrangler ecodiesel (3. 0l v6). Within 73,000 miles, both the primary and secondary turbo charge hoses have hardened, cracked, and failed under standard boost pressure. Safety risk: when these turbo charge hoses split, the engine experiences an immediate and complete loss of boost pressure (limp mode / code p0299), severely restricting acceleration and vehicle speed. This sudden, unannounced loss of engine power occurs while driving at highway speeds, creating a severe rear-end collision hazard in heavy traffic. Failure history & repair documentation: first hose failure: replaced by an authorized Jeep dealership at under 60,000 miles (November 2025). Second hose failure: replaced by an authorized Jeep dealership at 73,000 miles (August 2026). Stellantis/Jeep treats these recurring structural hose splits as non-warranty "wear and tear," forcing out-of-pocket repairs despite the severe highway safety hazard caused by sudden power loss. I am requesting NHTSA open a safety defect investigation into the material failure rate of 3. 0l ecodiesel charge air hoses.

Vehicle went into “limp mode” as I was entering an intersection. Pressed accelerator to the floor and vehicle would only sputter and crawl slowly. Vehicle towed to dealership. My safety and the safety of others was put at risk as the vehicle, without warning, essentially stalled while driving. If there were other vehicles on the roadway, this could have easily caused an an accident with injuries or worse. Yes the problem was comfirmed by the dealership. Yes the vehicle has been inspected by the dealer and manufacturer engineer. Dealership reports high voltage battery needs replacement. Dealership states that they cannot guarantee this won’t happen again even after battery is replaced. Check engine light was illuminated.

Battery pack replacement twice and engine replacement this Jeep had problems right after I got it new been in the shop 12 times over and over again they can not get it right.

While traveling at highway speed on the freeway, the vehicle experienced a sudden and complete loss of motive power/engine shutdown without prior warning. The instrument cluster immediately displayed a vehicle graphic outlined with red lines alongside an alert message instructing to shift the vehicle into park and turn the engine off. > the sudden loss of propulsion in live freeway traffic created an immediate safety hazard and collision risk while attempting to navigate across active lanes to the shoulder. > the vehicle previously had its high-voltage traction battery replaced approximately one year ago under warranty. The vehicle has been taken to an authorized dealership for diagnostic scanning and triage. Dealership said they can do a software update… that’s not okay.

The contact owns a 2020 Jeep Wrangler. While the contact’s daughter was driving at an undisclosed speed, the engine temperature gauge became extremely elevated. The vehicle was towed to an independent mechanic, where it was discovered that the coolant reservoir was empty and no leak was found. The coolant reservoir was refilled, and the vehicle operated normally. The dealer was not contacted. The manufacturer was made aware of the failure. The failure mileage was approximately 64,000.

Following the completion of the 68c recall update on 4/17/26 my 2024 Jeep 4xe experiences a severe loss of acceleration and throttle lag at highway speeds (over 50 mph) when in electric mode. When attempting to pass vehicles (and sometimes when in the oncoming traffic lane), or when just trying to maintain speed in traffic, the drivetrain abruptly throttles power; causing the vehicle to bog down and hesitate. There is no ability to accelerate and care slows. The gas pedal is essentially useless. The gas engine then performs a panic start, causing the vehicle to lurch forward at highway speeds. It has created and dangerous driving condition when passing, merging or just trying to keep pace the traffic around me. There is no way to know exactly when it will happen, so the unpredictability makes it even more dangerous. I understand this is an issue with many Jeep 4xe since the 68c recall update. It has happened to me 4 times now, the most recent was today. This is unacceptable.

Vehicle engine light comes on and says loss of power restart engine. Dealer found no codes and no repairs were made. This is the second occurrence.

I took my 2022 Jeep Wrangler to my local Jeep dealership for a 21d fire risk campaign recall inspection and powertrain software update. Car had to be towed to dealership a few days after services were completed, and was diagnosed at dealership, with an offline tcm, throwing a u0101 code. Car was in good working, driving order prior to the recall and software update and is now completely inoperable.

I am requesting NHTSA investigate the handling of safety recall 78c on my Jeep Wrangler 4xe. My vehicle has entered a dangerous highway limp mode multiple times, including at approximately 75 mph, with sudden loss of power and an acc! warning. This is especially dangerous on California highways and steep grades where losing propulsion can make it impossible to maintain traffic speed or safely reach a shoulder. The acc! warning has appeared three times. On one occurrence, while the warning was active, o’reilly auto parts scanned the Jeep and documented pending code p2338, cylinder 3 knock control threshold. I have the printout showing my VIN and mileage. The problem is that the warning/code clears after the ignition is shut off. When the condition happened on a Saturday, the Jeep service department was closed. Dealership sales staff refused to scan it and said only a technician could use a scanner. Even during business hours, the dealer says only a technician can scan it, but technicians may not be available for days. It is impossible to leave the vehicle running indefinitely waiting for someone to scan it. The santa maria Jeep dealer has now driven the vehicle twice and says that because the warning did not reappear during those short drives, they cannot confirm the condition. These events have occurred days apart, so two short test drives do not rule out an intermittent engine defect. I had the Jeep towed through Jeep roadside assistance because I consider it unsafe to drive. Jeep cares has assigned me three different case managers in three days. They state they cannot require the dealer to examine deeper stored diagnostic data because they are third-party contractors. I have photos of the acc! warning, the p2338 diagnostic report, VIN, mileage, tow documentation, and repeated loss-of-propulsion history. Jeep cares and the dealership won't look deeper or longer even with the proof it was there.

While driving my vehicle, I have noticed a significant decrease in power and a corresponding slowdown, particularly in traffic conditions. This has resulted in a near-miss collision with another vehicle in the rear. Furthermore, attempting to accelerate the vehicle has proven futile. Ps. The dealer where I brought the vehicle is kinda giving me a hard time & I fear for my family safety. Honestly I dont feel like the dealer was being completly honest.

Engine temperature went up while driving. The warning light came on and I immediately pulled to the side of the road. After 6 minutes on the side of the road the engine started to smoke and then caught fire.

My 2023 Jeep Wrangler 4xe high altitude received fca recall 68c. Since the recall was completed, the vehicle has experienced repeated and unpredictable reductions in available propulsion during normal driving. The problem is most noticeable when accelerating to merge onto highways, enter traffic, or pass slower vehicles. During these situations, I depress the accelerator expecting normal acceleration, but the vehicle frequently provides significantly reduced power. There is a noticeable delay before the gasoline engine produces sufficient propulsion, leaving the vehicle unable to accelerate as expected for several seconds. Based on my experience, the condition is significantly worse during hot weather. As outside temperatures increase, the hesitation and reduction in available propulsion appear to occur more frequently and are more pronounced. This has caused me to lose confidence in the vehicle's ability to accelerate when needed. This condition creates a serious safety hazard because surrounding traffic continues at highway speeds while my vehicle is unable to accelerate as commanded. In [xxx], this hazard is particularly acute because many interstate and highway entrance ramps are relatively short, requiring drivers to accelerate quickly to merge safely into traffic traveling at highway speeds. When the vehicle unexpectedly limits propulsion or delays engaging the gasoline engine, there may not be sufficient distance to reach the speed necessary to merge safely, increasing the risk of a collision. The same issue also affects attempts to pass slower vehicles on two-lane highways, where timely acceleration is essential for safe operation. The vehicle does not display diagnostic trouble codes or warning messages when this occurs. Because no diagnostic codes are stored, I have not taken the vehicle to the dealer, as other owners have reported that dealerships are unable to identify or repair the condition in the absence of fault codes. The lack of diagnostic codes information redacted pursuant to the freedom of in.

The first time happening I was driving on the interstate going about 70 miles an hour in the dark, the car completely shut down with no warning I was able to coast then tried to restart the vehicle and it started. I was able to get off the road and to my destination. The second time this happened, it was 5am in the morning getting on the interstate going about 40 miles an hour I got to the end of the ramp and merged into traffic again no warning the car shut down. This time the vehicle would not restart. I was able to coast to the shoulder with traffic approaching on me. Had to wait for a tow in the dark by myself.

The harmonic balancer on the motor failed and flew off the motor causing catastrophic damage to the radiator. The failure resulted in immediate disabling of the vehicle, which could have happened at high speeds or on a highway with limited access. The part that flew off the motor was also a large piece of solid metal that luckily landed in the bumper cavity, but if it would have left the engine compartment, would most certainly be a fatal projectile. Once taking it to the dealership, they told me that this is a known problem with the hemi 392 motor. Research shows this has been an issue since 2003 with this motor. The motor is found in several different stellantis vehicles. There were no warning signs of the failure prior to it occurring.

When using electric mode, repeatedly and consistently, when I try to accelerate (for example to get onto a highway) despite having the acceleration fully depressed, the car does not accelerate. After some time, the gas powered engine will rev, the rpm will shoot up and then the car will start to accelerate. If I slow down the electric engine will take back over, but then if I try to accelerate again the same thing will occur. I have videos of the dashboard confirming electric mode, delay to accelerate and eventual activation of the gas motor and rpms. This same issue was noted by Jeep technicians after the fix for a previous recall on the battery. This is dangerous, if I am not able to accelerate I can not safely drive change lanes, go onto highways, or avoid danger. It has been occurring, but my first video is from Feb 2026, and most recently July 2026.

I was driving my 2024 Jeep Wrangler 4xe on a public road when the vehicle experienced a sudden loss of propulsion. Before driving, the check engine light was illuminated, and the air conditioner was blowing hot air instead of cold. Shortly after pulling onto the roadway and while approaching a stoplight, the vehicle lost power while it was still in motion and became inoperable, requiring it to be towed to the dealership. The dashboard displayed “service hybrid electric vehicle system. ” the vehicle has fewer than 20,000 miles. I believe this is a serious safety concern because the loss of propulsion occurred while driving, leaving me stranded in traffic. I no longer feel confident in the safety and reliability of this vehicle.

While driving on the highway, the check engine light illuminated. Approximately 5 to 10 minutes later, the battery warning light came on. Upon exiting the highway and coming to a stop at an intersection, the automatic engine start/stop system engaged and shut down the engine. When attempting to safely proceed, the vehicle suffered a complete electrical failure due to the 48v mild-hybrid etorque system failing to restart the engine. The vehicle refused to crank, would not shift, and became entirely disabled and stranded in the middle of a live intersection, creating an extreme safety and collision hazard. The vehicle was towed to an authorized dealership, where technicians officially confirmed the failure. The dealer diagnosed the root cause as an internal electrical failure of the motor generator unit (mgu / belt-driven hybrid starter generator assembly), which completely disabled the vehicle's charging and hybrid restart capabilities. The failed component is available for inspection.

Drove 20 miles to walmart, drove fine no lights no issues, parked went in came out to someone putting out the fire.

What component or system failed or malfunctioned, and is it available for inspection upon request?multiple components across four separate manufacturer safety recalls: (1) the high-voltage battery (recall 68c), currently being replaced by the dealer; (2) the hybrid control processor / drive system (recall a7c); (3) the electric hydraulic power steering pump (recall 21d); and (4) the 2. 0l engine (recall 78c, status disputed — see below). The vehicle is currently at the authorized dealer and is available for inspection there. How was your safety or the safety of others put at risk?recalls 68c and 21d are both manufacturer-designated fire risks; 21d specifically carries an "urgent: fire risk when parked" designation in NHTSA's own database. Recall a7c describes a loss of drive power without warning while driving, which the manufacturer states may cause a vehicle crash. I experienced a stalling event with the drive indicator blinking on 10/17/2025 (10,553 miles); unknown whether this was directly caused by the a7c defect, but the symptoms match the recall's description. Has the problem been reproduced or confirmed by a dealer or independent service center?the 68c battery failure has been confirmed by the dealer, who is currently performing a full battery replacement. Unknown whether the 10/17/2025 stalling event was ever formally diagnosed as connected to recall a7c; the dealer's repair order for that visit does not reference a7c or a root cause. Unknown whether recall 78c's applicability to my vehicle has been confirmed or denied by the dealer — see discrepancy described below. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?the vehicle has been inspected and serviced multiple times by the manufacturer's authorized dealer. Unknown whether any fca/stellantis field engineer or investigator has separately inspected it. No police involvement; no c.

My 2024 Wrangler 4xe has 27,000 miles on it. On Friday, 7/10/2026 around 7:00 in the morning the check engine light came on. I immediately called the dealer to set up an appointment and they could not get me in until 7/15/2026. At about 9:30am that day when I was pulling a small trailer the battery light also came as I was driving on the interstate. As soon as I exited and slowed down, the car lost all power. It would not start or move. I was stranded on the exit ramp in the turn lane, with a trailer, unable to get to the shoulder. There was quite a bit of traffic around me. I was able to have it towed to the dealer. I had to safely get out of the vehicle and direct traffic around the vehicle. Today, 7/15/2026, the dealer ran the diagnostics and determined that the hybrid battery has failed and needs to be replaced. The car currently has 27,000 miles on it and this is now the second hybrid battery replacement and the third time the Jeep has stranded me and has required a tow to the dealer. It is unreliable and unsafe as it becomes immobile and loses power on the roadway.

The contact stated that while driving 15 mph the vehicle experienced a complete loss of automotive power, the steering wheel locked up, and all of the warning lights were illuminated. The vehicle came to a complete stop and was restarted. The contact continued to drive the vehicle was taken to a local dealer where it was diagnosed and the contact was advised that no failure was found. The contact continued to drive the vehicle, and the failure reoccurred while driving at 75 mph, the vehicle experienced a complete loss of automotive power, the steering wheel locked up, all of the warning lights were illuminated, and the following the message appeared on the instrument panel "until you reach a desired location you may not be able to shift until serviced, do not take the vehicle out of gear until you are in a safe location". The vehicle was towed back to the dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 17,592.

On July 1,2026 , my 2020 Jeep Wrangler jl sport died in the middle of traffic causing a safety issue. I was not able to start my Jeep and move out of traffic. I was able to disable the transmission and roll out of the road. But it was very dangerous while cars were passing me and coming towards me. Also before I was able to disable to roll my steering column was locked. The cause of this safety issue is the set up of the batteries. A Jeep has 2 batteries a main and underneath an auxillary battery. Without any kind of warning your battery can die caused by the drain of the auxillary battery on the main battery causing the main battery to just stop working without notice. This is the 2nd time this happened. I had to call a tow truck both times. 1st time 4/14/24, then on 07/02/2026 I had it towed to the same dealership as the time before. This is an on going issue with Jeeps that have the 2 batteries. Not only is it unsafe but a costly issue.

Failed emission test and the car is 6 years old. I have had this car in for the death wobble and told them the engine fan stays on. It has done this for years. Dealer kept stating it just had to cool off. The Jeep vehicles that have the deal wobble should be recalled very dangerous. I have videos I can submit.

My 2016 Jeep Wrangler will buck and jerk when on the highway. I’ll be going a steady speed, not changing speed. I feel the car slow down and stomp on the gas but it goes all the way to the floor and nothing happens. When I try to go into the break down lane, the steering wheel locks up and won’t turn. Usually I take the key out then put it back in the ignition and it starts no problem. Recently, the engine has been stalling when I put the key back in the ignition. I usually have to take the key out and sit on the side of the highway for 5 minutes before starting it up with no problem. This has happened too many times than I’d like to admit. Take it to the shop, no codes come up. Sometimes the engine light will turn on when this happens, other times it doesn’t.

I own a 2022 4xe, ater the 68c recall the power of the electric drive is limited. Frequent power loss occurs on highway driving during acceleration (merging onto highway or passing other cars). Despite the battery being charged up to 50% there is only 25% power available. The car is a plug in hybrid vehicle. The internal combustion engine starts in these cases with several seconds delay. During that time the vehicle does not accelerate sufficiently to safely merge onto a highway or pass other cars. The power loss happens without warning during critical drive situations like merging onto a highway or passing other cars. The driver expects a continuous level of power by the car, not a sudden power loss. This is reported by countless other drivers on all social media platforms as a consequence of the 68c recall that affects 350 000 Jeep Wrangler 4xe and grand cherokee 4xe. Jeep does not respond to customer complaints or requests for clarification. I would like to request all these cases be looked into, and also contacting Jeep for the new parameters put in place to protect the battery, such as battery temperature and power limits put in place to "protect" a hardware issue within a battery with software.

I went to start my Wrangler 4xe today and had a "service charging system" error. The gas part of the Jeep was running, so I proceeded to drive it. I noticed when I came to a stop, the car would not accelerate, then when it did it was violent and bucking. At a stop light it sounded like it was going to stall so I turned it off and then it would not turn back on at all. I finally got it to turn back on and drove it a little further, at one point I went to accelerate and had the pedal all the way to the floor and it would not advance. I brought it to auto zone and had a new 12v battery put in, but it did not fix the issue. After a quick search, it seems like this is a common problem with Jeep 4xe high voltage battery systems. Jeep has recalled the battery at least 3 times now and I've taken it for the first two recalls already. It was extremely distressing to try to accelerate and it not move, and could have seriously been a safety issue if I continued to drive the car. I was in another state, Jeep has no 24/7 service to call other than roadside assistance, so I had it towed to brubaker Jeep in lancaster PA, but I live in virginia and had to rent a car to get home.

When I am driving I will lose power and not be able to drive while I am in the middle of a road driving. And I have to turn my car completely off to let it start back up. The dealership doesn’t not seem to have any more suggestions or recommendations. I feel unsafe driving this vehicle. This keeps happening.

2023 Jeep Wrangler sahara 4xe has been recalled several times for battery potential fire risk issues due to faulty hi voltage battery design. Each time, a software patch was applied to provide a 'fix'. With my engineering background, I am very sensitive to machinery and its behavior. I have noticed with each successive update, the power output of the traction battery has been capped or limited to restrict maximum current draw from the battery to prevent over heating. With the latest 68c recall, there is now a clear safety issue. Power is restricted so much, pulling on a highway is dangerous. As I accelerate, battery output climbs to 50%, the engine comes on and there is a significant pause before acceleration can resume safely. Under battery only acceleration, the car bogs down with loss of power. The 4xe no longer resembles the vehicle I purchased. Jeep needs to do a physical remedy to restore original specs or buy back the car, 100% of purchase price. This is a clear safety issue. While Jeep has tried to fix the fire risk, they have created a new safety hazard.

After performing the 68c recall vehicle no longer drives the way it was designed. When in hybrid mode pushing the accelerator to the floor results in a 2-6 second delay waiting for the gas motor to kick in and then it slams the power into the car. This car is extremely unsafe and impossible to merge into the highway correctly now. Car does not show any warnings and dealer claims this is normal operation.

When driving on the highway the Jeep would not accelerate. At about 60mph no matter how far I pushed the petal down it would only maintain speed. It happened again going much slower on local streets.

Was traveling approximately 55 mph down the highway for 15 min in electric mode. Moved to the shoulder and stopped quickly using regenerative braking for an oncoming emergency vehicle. I got back on the highway and I suddenly lost almost all pedal response and it would not accelerate. I kept pushing the accelerator pedal harder and harder. That's when the ice kicked on and there was a sudden violent lurch forward and the engine was screaming at over 5000 rpm. There were cars approaching behind me and they had to suddenly stop and they honked horns and avoid hitting me. This sudden throttling of the battery/electric and very erratic switch over to ice is dangerous.
