Engine And Engine Cooling Problems of Jeep Wrangler - part 1

My local dealer has all the documentation on this Jeep. It has been into the dealership many times now the check engine light is on for another problem which I am taking it in again this weekend . When I ask the dealer, I’ve been seeing things on facebook about these Jeeps having issues they just filled me full of a bunch of bull and says every vehicle has issues. I’ve ran the VIN number and found out that mine is one of them that just catches on fire plus sometimes shakes when it’s driving down the road but that’s been minor considering everything else. One time I was driving up the driveway and it felt like the transmission slipped or something. They said it was something in the four-wheel-drive that went out. This is a new vehicle. It has very low miles on it. I’ve had it going on maybe the fourth year now it’s only got 31,000 miles on it I don’t drive it very far. It’s been in the shop several times for recalls or things that’s happened to it. When I first got it, it left me stranded would not start. I’d only had it a few days. It has been a lemon from start to finish. I am terrified to drive it and I don’t have another vehicle. I paid $55,000 for this Jeep just a few years ago. I don’t know what I’m supposed to do. I desperately need help if the manufacturer is refunding people’s monies I want to make sure that I get enough money to buy another vehicle because this one is only a few years old and it’s been in the shop numerous amount of times. The other day it shimmied a little bit on the highway and I thought it was the road and now I’m reading that there’s problems with that also, it’s clearly a lemon. But as I said, I’m scared to death to drive it now. The newest development as I’ve said is now the check engine light is on. It’s only been out of the shop for maybe three weeks since they fixed something in the four-wheel-drive which I’ve never even used. I love the looks of this Jeep, but it’s not dependable so I need help.

The vehicle exhibits a persistent valvetrain ticking noise associated with the rocker/lifter/cam components of the 3. 6l pentastar v6. The engine makes a rhythmic metallic tapping at idle and during acceleration. The noise has progressively worsened, leading to rough idle and occasional misfires. This issue is documented in multiple stellantis technical service bulletins (e. G. , TSB 09-015-24 and TSB 09-011-25) which attribute the noise to hydraulic lash adjuster and cam/rocker wear. If unaddressed, the failure can cause camshaft damage, metal debris contamination, loss of power and potential engine stall, posing a safety risk. The vehicle is available for inspection. The problem has been confirmed by independent mechanics who recommend replacement of the rocker arms, lifters and camshaft to prevent catastrophic engine failure.

On October 25th, 2025 my husband and I were driving home on the freeway. All of a sudden, without any warning notice or check engine light, my hybrid 2023 Jeep caught on fire as we were in it driving down the freeway. The fire started under the hood and under us. Flames were coming up the sides of the Jeep as we drove and were getting bigger then coming in the vents and under the hood. My husband pulled the Jeep over to the shoulder and we quickly got out and away from the Jeep and called 911 for help. Cars were still driving down the freeway as the Jeep was engulfed in flames. Our safety was put at high risk since we were driving on the freeway at highway speeds and the Jeep caught on fire without any warning and my husband and I were sitting inside the Jeep traveling while it was actively on fire and getting worse. We were located right by the fire as we were driving. It was under us, in front of us and growing around us. Others were put at risk because there was a large fire on the side of the freeway as other vehicles were driving by. A semi truck almost hit the median in the freeway when it probably noticed what was going on. Further, vehicles were driving in the right hand lane right beside the active fire. My Jeep was sparking, throwing flames and some things exploded. Jeep hybrids have had problems and my Jeep has had many recalls and problems. Stellantis was involved with the last few dealership service visits. The Jeep was not charging so a new charging system was put in it at the dealership. The Jeep had a red turtle come on as I was driving and it drastically slowed my speed down suddenly. I pulled over and then my Jeep turned off and would not start again for hours. The dealership, with stellantis involved, put in a new rechargeable battery. These were some of the things done recently prior to my Jeep catching on fire en route in addition to many recalls/updates. There were no warning signs at all prior to his Jeep fire.

I was driving the Jeep on route 35 in NJ when all of a sudden, the car lost power, jerked forward thrusting be towards the windshield. The "d" on the gear shift started blinking and the check engine light went on. The dashboard message indicated something along the lines that I had to put the car in parking "p". The car behind me beeped and almost rear ended me as it's a fast road and my car slowed dramatically and unexpectedly. Ultimately, I was able to glide into a parking lot on the side street and called the tow truck. The dealership said that a faulty ota was sent out which caused the issue and that it has happened to many people. There were no symptoms or warning lights prior to the event. The dealership updated the vehicle and said it was safe to drive but I am not convinced based on the experience of others, which I have read in forums, who have had the same thing happen multiple times even after having the dealership update installed. Apparently, this ota issue was widespread.

I was driving as normal in a 40mph zone when my car stalled, steering locked up, and it flashed to put it in park in the middle of traffic. I was able to move over to a safe space after putting it in park but it kept shutting off as I inched my way off the road with hazards on. There was an update that went out that was causing this to vehicles and I was declining the update as suggested by manufactuerer by pressing the red x but it somehow forced installed itself while I was driving. Then while I was pulled over it would run for a few seconds then it would all of a sudden shut off again saying e-drive mode temporairly unavailable. Ive attached some photos but have a video of it running and shutting off if you would like me to send that.

Due to a recent over the air update which impacted the hybrid system, the car would lose all power and require to stop the car completely and restart the vehicle. This is a known issue that has been acknowledged by Jeep/fca. After it occurred the first time, a check engine light came on and stayed in. The stalling event occurred approximately 5 times in a short trip with several of our small children in the vehicle. Luckily, we were driving on local roads with the ability to pull over without putting ourselves in danger, but cannot fathom how Jeep would put thousands of drivers at risk, especially if they were driving at high speeds or maneuvering.

On October 16, 2025 an unaccepted other-the-area software update from stellantis could a serious vehicle malfunction where my 2024 Jeep Wrangler 4xe stopped driving and I could not get it to drive without turning it off and on again. Then, it drove with almost no power until it stopped again. I cvcled my vehicle on and off several times to get it to safety.

My vehicle shut off as I was accelerating.

Jeep 4xe complete loss of power while driving almost caused a huge accident. No power, no power steering totally dangerous and they knew damn well this would happen but didn't alert customers!!!.

The check engine light illuminated and diagnostic code p219a was recorded (bank 1 air/fuel ratio imbalance), and the engine has a ticking noise. The dealership has indicated the issue likely involves the valvetrain/rocker arms/lifters and will require engine internal repair (valve cover removal, spark plug replacement, possible rocker arm replacement) estimated at ~$2,900-$4,500. The 3. 6 l pentastar engine has been the subject of numerous owner complaints of ticking noise, power loss, misfire, and premature valvetrain failure. I understand there have been related Jeep technical service bulletins (such as 09-002-14 and 09-008-18) addressing these types of failures. A class action lawsuit (maugain et al. V. Fca us llc) alleges defects in the 3. 6l pentastar engine’s valve train (rocker arms, lifters) and failure to disclose the defect. Maintenance history: regular oil changes (every <6,000 miles) at approved service centers; no prior major engine internal repairs. Concern: the defect affects engine performance, may lead to catastrophic engine failure, and potentially reduces safe vehicle operation and control (power loss, hesitation). Relief sought: I request the NHTSA open a vehicle safety defect investigation and compel fca / Chrysler / Jeep to evaluate this condition under recall criteria.

Jeep pushed out an update on Friday 10/10 that we were advised to decline as it was causing mechanical failures. Despite declining the update ever since, and being assured that this remedy would work until the update expired in 30 days, apparently it still managed to push through on its own last night. I was less than two miles from my house this morning on my way to an appointment when the dashboard lit up and the Jeep completely lost power. I shut it off, turned it back on and was able to get back home, but the cel is still on. I was lucky enough to be on a side road, as I was about to enter a busy intersection. I've talked to Jeep and they do not have a fix, but it is unsafe to drive at this point. I am waiting on a towing company at the moment to bring it to a Jeep dealership.

It updated the software then after that while I was driving the car suddenly died. Lost power. Almost got hit from behind but I was lucky to be able to get on the shoulder.

After installing an ota update . The vehicle kept stalling while I was driving it . It stalled 3 times in less than half a mile . Completely stops midway all lights on dashboard start flashing asking to be put on park then start . This is extremely dangerous while driving especially on freeways. I almost got rearended at least 3 times when this happened. My safety and the safety of everyone on the road that day was risked.

Car flashed “shift to park”, stalled in an intersection and now check engine light is on. This is related to Jeep’s ridiculous and unacceptable software issue. Despite a “fix” being allegedly issued by Jeep, this issue still happened today November 14th despite me never accepting their flawed software update. This is an alarming safety issue.

Driving normally then loss of power and forced us to pull over. Check engine light on. Super, super dangerous. This is after an ota update. Many other Jeep Wrangler owners reporting the same issue: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After a uconnect software update was performed the vehicle shutdown. Upon starting the vehicle the check engine light came on with several other dashboard lights and after driving the car for a few seconds the engine would shut down and would say to park and turn off vehicle. After a couple restarts and experiencing the same shutdown two more times I was able to drive in e-save but felt the vehicle was in limp mode and the engine light still remained illuminated. Called the Jeep dealership and explained the problem and the first thing they asked was did you just do a software update. I said yes and he said that’s the problem that they just had 35 Jeep Wrangler 4xe’s towed to their dealership yesterday. He said that Jeep does not have a fix for the issue as of yet. It throws a fault code p1e1d. So seems that the recent uconnect software update is rendering all Jeep Wrangler 4xe’s useless.

While driving on the road the vehicle suddenly loses power and shuts down. The check engine light illuminates and a message saying shift to park appears on the dashboard. You have no control of speed at this point. The vehicle stops and stalls in the middle of the road. Once you shift to park you have to completely shut off the vehicle while in the middle of the road and restart the engine. The vehicle will drive a few hundred feet and repeat the stall. It is completely scary and dangerous.

Driving down the road, Jeep suddenly says shift to park and loses all power stalling in the middle the road. This happened twice on October 14, 2025 and needed a tow truck to be brought to a dealership. When it loses power everything locks up including steering so you can even pull over safely to the side of the road. This is a very serious issue that can easily cause a deadly accident and needs to be addressed.

Put a brand new battery in my vehicle - 3 days later driving on the highway had full loss of power - if said to service the charging system, and to put the car in park, then to press the brake and start button to start the vehicle. Went from 75mph to 25mph - rolled off the highway.

After an ota update, while driving, the vehicle abruptly stopped working and I was forced to pull over. The check engine light went on and a message requesting service to the electric charging module was shown. After cycling power a few times the car worked again. This happened again on the way home. The manufacturer Jeepcares account advised that the car needs to be towed to a dealer immediately.

The Jeep die while I was driving on cr530. Check engine light came on and stuff flashed I quickly pulled over rto the shoulder. After ten minutes I was able to drive it into a dunkin donut shop but it turned off three times risking my life each time. I had my hazard lights on but people dont care. Called dealership and waited for the Jeep to be towed.

Complete loss of power in vehicle after an update.

In the middle of driving, with the new update alert of uconnect box (I wasn't updating the uconnect), the car suddenly stops in the middle of the road and told me to shift to p (parking) to start while I am on d (driving mode), then, lost power and stopped. After turned it all the way off and back on, the cel came on. The car would drive, proceeded on and within a few minutes, it did it again. Loss of power and it is telling me to shift to p and press power to start.

The Jeep turns off at random times that I have to coast to a stop, put it in park, and then try and restart it again. That’s dangerous going down a highway and the Jeep to completely lose power and shut off or going through an intersection and having the Jeep shut off.

On October 13, 2025, I experienced three separate incidents involving my Jeep Wrangler 4xe while driving in hybrid mode at approximately 35 mph. First incident: around 5:10 pm, the vehicle suddenly lost speed, stalled erratically, and displayed the message “shift to d to drive” on the screen while the “d” on the gear selector was flashing. The check engine light also came on. I was able to safely pull over and restart the vehicle. Second incident: around 5:13 pm, less than a mile later, the same issue occurred again while the check engine light remained on. I again pulled over and restarted the vehicle. Third incident: around 5:20 pm, the same problem repeated for a third time. After the third occurrence, I called the dealership where I purchased the vehicle to report the issue. The service department representative immediately recognized the problem and informed me that 13–14 vehicles had already come in that same day with the same issue. Because I was only about 3 miles away, I drove carefully at low speed with my hazard lights on and dropped off the vehicle at the dealership. At the service center, the staff member stated that it might be an electrical issue possibly related to a recent uconnect+ software update. However, I had not received any prior information, warnings, or recall alerts regarding this issue — neither through the Jeep app nor by email. I am especially concerned that the dealership was aware of multiple vehicles with the same issue yet provided no notification to affected owners. I later discovered that other Jeep Wrangler 4xe owners have reported the exact same issue — the dash blinking “d” while driving, sudden loss of motive power, and the message “shift to d to drive” appearing even though the vehicle was already in drive. These reports match my experience precisely, indicating that this is not an isolated problem. This is an extremely serious safety issue. The vehicle’s loss of motive power while driving unexpectedly puts drivers and.

After the update it did, it will only drive like 20 feet. We lost acceleration and power in the middle of a busy road numerous times. Had to restart the vehicle every time. Severe safety issue, we had to coast into an intersection through a red light because we couldn’t stop because the engine kept stalling.

Car stopped dead as I merged into a major highway and said hybrid battery issue and requested to be moved into park. I turned off the car and on and put it in esave mode to move it - very dangerous.

The Jeep lost power after only driving abojt a mile down the road. All the lights came on the dash and I had to pull over until it came to a slow stop, the brakes didn’t seem like they working. Once in park I got a dash light that said service charging system. I was not able to move it out of park to even neutral. After about 15 minutes I was able to get it to start and drove it home about 1 mile- it did the same thing. When it restarted the check engine light is on.

While driving, all of the lights started flashing and was told to shift into park right away and the car stopped and turned off.

Engine died while driving.

The contact owns a 2022 Jeep Wrangler. The contact stated that while driving approximately 65 mph, the vehicle started losing motive power. The contact depressed the accelerator pedal, but the vehicle failed to respond as needed. The contact stated that the message "performance issue" was displayed, and a red light was illuminated. The contact stated that the vehicle stalled. The contact was able to restart the vehicle and drove the vehicle to a local dealer. The dealer was unable to diagnose the vehicle, and the vehicle was not repaired. The manufacturer was not informed of the failure. The contact stated that months prior to the failure, the vehicle was repaired under NHTSA campaign number: 24v720000 (electrical system) by the same dealer. The contact related the failure to the recall repair. The failure mileage was approximately 50,000.

This morning my 2024 Jeep Wrangler 4xe check engine light came on and had a loss of power. I had to pull over onto a highway to restart the vehicle. The dealership stated that there was an over the air update that was faulty and that they had no way to fix it, but they stated to bring it into the dealership service department even though vehicle is currently not drivable or unsafe to operate.

Jeep over the air update caused my car to shut off completely in the middle of an intersection. I had to come to a complete and violent stop and restart the car. This happened three more times trying to get home - with kids in the car - though thankfully subsequent times were kess precarious because I took side streets and was careful.

The car updated with the latest uconnect on Friday night. The next morning car drove fine for about . 5 miles, the drive gear selector on the screen started to flash with no power to the car. The car had stopped accelerating in heavy traffic with no where to pull over on the side of the road. Performed same issues 3 times, after the third time the car went into limp mode. Had to be towed to dealer, it is currently in service on limp mode with no next steps.
