On at least 6-8 occasions car engine has shut off and car is automatically placed in emergency brake. This then requires you to place car in park, then restart vehicle. This happens while driving on interstate and when car slows down for traffic car engine without warning, will shut off, car will then automatically turn on emergency brake forcing sudden stop in interstate hwy traffic. Very dangerous as you have to place car in Park and restart engine. Cars behind you are now slamming on brakes to avoid rear end collision. This has also occurred while sitting at traffic light when again car engine shuts off and has to be placed in park to restart. There is no warning, no warning lights, no check engine after incident occurs and according to dealership no engine codes recorded due to incident. I have left car at dealership on several occasion for several days. I believe it was replicated at dealership but again it registers no codes in engine computer to help resolve issue. When a car traveling down the interstate suddenly shuts down it is extremely dangerous placing my car and family at risk as well as any traveling behind us. Dealership has not been able to resolve issue. They can update software and the car will go several weeks without issue then suddenly you are back to engine shut down again I am second owner of 2024 Jeep Wagoneer S II Carbine. Purchased at GMC dealership. At time of purchase dealership provided maintenance records which showed no issues of engine failure. Unfortunately Jeep is not going to document this issue and does not appear to have a solution. This is an extreme safety concern

My 2024 Jeep Wagoneer L with the 3.0L Hurricane engine began experiencing drivability and warning-light failures at very low mileage and within the first year of ownership. The vehicle was purchased new in October 2024 and experienced its first major drivability/towing event at approximately 10,372 miles. Over the following months, the vehicle experienced repeated check engine light events, shaking, sputtering, hard starting, loss of throttle responsiveness, drivetrain hesitation, and multiple towing incidents despite repeated dealership repair attempts. The most severe safety event occurred in May 2026 at approximately 18,850 miles while traveling on the interstate with my family and young children. Prior to this event, a Florida Jeep dealership documented diagnostic codes P21A0 (Cylinder 5 Air/Fuel Ratio Imbalance) and P0430 (Catalyst System Efficiency Below Threshold) and specifically documented in writing that “the #5 fuel injector is causing the fault” and likely damaged the catalytic converter. Despite this, we were advised the vehicle should be safe to drive home. While driving on the highway the following day, the check engine light began flashing and audibly beeping continuously, the vehicle began shaking aggressively, and acceleration responsiveness deteriorated significantly while traveling at highway speeds. We were forced to immediately exit the highway and abandon the vehicle at a Jeep dealership in Georgia due to safety concerns and fear the vehicle could become unresponsive in traffic. The vehicle has been inspected multiple times by authorized Jeep dealerships in South Carolina, Florida, and Georgia. Earlier repair attempts attributed the issues to software/update-related causes. The Georgia dealership later replaced the catalytic converter but did not directly address the injector-related concern because the condition was not actively reproducible during their inspection despite the prior dealership’s written findings.

I purchased car less than 24 hours ago. Service engine light is on. Dealership ran code and say it wasn't diagnosing a problem. And engine light went off. Drove for 3 hours and then engine light came back on. When I drove the car today, I came to a stop at a stoplight and when I went to go the car would not go. Looked down and my car had been gone into emergency parking. This issue was NOT disclosed to me when I purchased the car.

We purchased a Jeep Wagoneer L from Liberty Jeep in Libertyville, IL in May of 2024 and have had issues since. The first issue was on August 25th 2024 when I was driving my vehicle it stopped in the middle of the road and turned off. I had to turn my car back on and thankfully was only a block away and drive it to my driveway with the steering stiff the whole way. After this, the Jeep had to come tow my car on August 26th. There was no warning until after it happened. Dealer had the car for one day and then said to come get it on August 27th it was fixed. My husband went to pick it up and as soon as he drove away the engine light went back on. So he turned around and brought it back in. It was in the shop from the 27th-Sept 13 2024. They said it was a catalytic converter that needed to be replaced. Since purchasing the vehicle the trunk had never fully worked. We would always need to mess with it to open or close. On Nov 1 2024 the car was brought in for trunk repair. It was there until Nov 6th 2024. Well they said they fixed it and then in Feb 19 2025 it was brought back in again for the trunk. It stayed in the shop till March 4th 2025 for trunk repair. They said they fixed it again. November 3rd 2025 car was brought back in for stiff steering. When I went to turn the car steering went stiff and I couldn’t turn. I had my daughter and her three friends in the car. On top of that the navigation screen was freezing and the camera’s weren’t working. They said it needed updates with the technology and all was good. On Dec 14th 2025 the trunk wouldn’t close. It would open when I was driving my 3 kids in the car. I had to have my [XXX] son sit in the trunk to hold the trunk closed so I could get us home. Jan 17th 2026 I would be at a stop light and my car would alert me to put the car in Park, Turn car on and off then put it in drive then it would say ABS service. This happened on a highway at a light multiple times. Someone could seriously be injured. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

My 2024 Jeep Wagoneer Series 2 frequently stalls while coming out of idle, such as at traffic lights. This is not the auto stop-start feature and happens whether or not auto stop-start is deactivated. Usually, after being by stopped, as I am getting ready to start moving again, the vehicle will slightly rev or try to lurch forward before stalling out. This turns the engine off, throws the car into park, and activates my e-brake. It happens before I press the accelerator so the car is not moving more than a mile or two an hour. This problem is dangerous because it creates a risk of accidents with other vehicles. When the car stalls in this way, I must confirm the car is in park, press the brake, restart the engine, deactivate the e-brake, and shift the car into drive before proceeding through the intersection. This takes a few seconds and if the driver in the car behind me isn’t paying attention and think I am starting to move, he or she could rear-end me. This problem has happened more than a dozen times (so not every time I drive but frequent enough to be a pattern). It can happen when I have been driving for a while and the engine is warm. There is no way for me to predict in advance when it will happen. It can go weeks without happening or happen twice in the same day. It does not activate any dash warnings (such as service engine light or an error code) that I can see. I have taken my car into the dealership twice for idle related issues including once for this exact problem. The last time, the dealership found misfires on all cylinders, both catalytic converters coming apart from the inside and 02 sensors that had melted from overheating. The dealership replaced all of this. My vehicle still stalled on the way home from the dealership. This time, I detected a strong rubber or plastic burning odor when I got home. The vehicle has less than 12,000 miles on it and was bought new less than a year ago. I attach last repair invoice.

Leaving for work this morning and reversed out of parking spot, tried to pull out onto a busy road and almost died. The car just kinda rolled forward a bit and would not accelerate or do anything! The ignition switch was blinking. I could not reverse or go forward or put it in park, the gear shifter lights were all blinking as well. I couldn’t shut the car off to restart it. I could not change gears or go anywhere but sit in the middle of an intersection with cars approaching me at a high rate of speed. It took approx 2 min for the car to do anything. It finally allowed me to shut it off and restart. Check engine light on. I reversed back into the parking lot I had exited from and drove it around to make sure I could accelerate onto this road where people do 70mph. I’m extremely lucky I did not get t-boned. I have read about this issue escalating to the car having this problem and told my dealership about this when i was having the check engine light issues mentioned below. I really do not feel safe in this car now after getting stuck in an intersection. Prior issue with wagoneer, it’s been to the dealership at least 4x for this: bumps you back into park when you try to reverse and then the check engine light comes on. I have to shut the car off, open my door, restart, and then it’ll go into gear and check engine light remains on until I bring it in or sometimes after driving a bit it goes off itself. There was some known issue with possible problems with the transmission regulator valve so they switched that out and said that should take care of the issue. But check engine light on again. It now progressed into being completely disabled at an intersection today.

Unexplained and dangerous transmission issue resulting in stalling while driving at low speeds, electronic malfunction, and check engine light which first occurred on 7/23/24 when the vehicle had roughly 3,500 miles. Vehicle was with dealer service from July 24-August 15, 2024. During that time, repair was allegedly attempted twice and vehicle returned to me on 8/15/24 after allegedly a replacement part was installed from Jeep/Chrysler HQ. Was told by the dealer service rep the issue was a known issue and other Wagoneers had been brought in with the same issue when I retrieved the vehicle. Dealer service could/would not confirm if issue was recreated but assume so since the vehicle was kept for so long. Sudden stalling and check engine light occurred again on 10/3/2024. Contacted dealer service on 10/3/2024; was told not to drive vehicle and a tow truck would be sent. Car towed to dealer on 10/4/2024 and returned again after alleged repair on 10/18. Issue occured again on 11/16. Have not brought it back to the dealer as I have filed for lemon law. Check engine light was on but went off a week later. On all three occasions, prior to the stalling and electrical malfunction, the car seems to be stuck in a low gear while driving and makes a grinding noise. The issue occurs when slowing down and has not happened at high speeds, luckily. Filing this with NHSTA as I see there is also an investigation into 2022 model for same issue.

With less than 500 miles on the vehicle, while stopped at a stoplight, the vehicle automatically shifted from drive to park and had to be restarted in order to accelerate forward. Check engine light also came on. When stopped at the same light again moments later, the same thing occurred. These events happened within a couple minutes of each other. Vehicle would not accelerate until restarted. Took vehicle to get serviced, the next day within minutes after leaving the dealership and servicing, the check engine light came on after accelerating at a stop light with the same engine error codes.

Vehicle is 4 months old and has 2300 miles on it. Randomly and suddenly the vehicle will lose power while in traffic. No steering or engine power. It will abruptly coast to a stop, put itself into park, and stall. Several lights will come on. All the lights but the check engine lights disappear after letting the car sit. The car sometimes turns over only to stall a few seconds later. If left to sit for 30 minutes or so, it will drive again. Obviously a car that shuts off and loses power while driving is a big safety issue. I am unsure if I should drive it again, in case it happens at the wrong time. This has happened on three occasions over the last 350 miles. 5/6/24 5/22/24 6/15/24 The vehicle has spent over thirty days at the dealer. They do not know how to fix it. On 6/15/ 24 one of the owners of the dealership was able to see the mechanical problems 1st hand.
