When driving the Wagoneer and on multiple occasions, the car shuts off in Drive and stops moving requiring me to then shift the car into park turn off the car and then restart the car and then move it back the drive this has happened on highways this has happened driving around local neighborhoods and is his hazardous to my family. I was driving in the car with my three kids and the car just stopped in a busy road with a lot of traffic and we all felt fear that it's something bad could happen as cars were flying by us. This is a major safety concern, and should be flagged to you all.

The check engine light illuminated on my dashboard when I was driving with my family. On 4 separate occasions as I was coming to a stop, the vehicle unexpectedly shut off (driving at about 5 MPH). When it shut off, it shifted itself into Park and the parking brake was auto-applied. On each of the incidents, I was able to manually restart the vehicle by pushing the ignition button and shifting it back into Drive.
Thermostat failed and car overheated, resulting in a high temperature warning. Had to take immediate evasive action to pull onto the shoulder in order to prevent complete engine failure.
Issues began on 9/29/26 - The transmission was slipping and failed to shift numerous times when accelerating causing a loss of power. This happened several times at highway speeds when passing. Warning lights came on after this issue occured. This issues happend several times over the course of about a month. These issues put my safety at risk multiple times when I was suddenly not able to accelerate to pass or in some instances not able to accelerate to enter the interstate. This issue also occured at a low...

speed in stop and go (interstate) traffic. The vehicle would not shift out of 1st gear and I was forced to drive on the interstate at a dangerously low speed until I could exit the interstate. Warning lights came on due to this issue. The Jeep dealership assessed the vehicle and determined that the transmission needed replaced. The transmission was replaced at a certifed Jeep Dealership. The vehicle was tested, deemed repaired, and returned to me. The next day the same issue occured where the transmission would slip, grind, and then lose power. That same day the vehicle lost power completely while driving. The engine shut off while I was driving. When I pulled over began to slow the vehicle automatically and abruptly shifted itself into park. This again put my safety at risk by the loss of power while driving and unexpectedly shifting into park. The vehicle is currently at the same Jeep Dealership being assessed. I
Vehicle will suddenly shut off in traffic. Will NOT start back up for 1-2 minutes. Control panel near gear selector will flash on and off message reading Hold brake and start button. Screen all black. This has happened 3 times this month. Car shut off in car wash, once started it would not shift from Park into Neutral or Drive for 60 seconds. When accelerating on expressway, vehicle will shake then message flashes on dashboard "Put in proper gas and oil". Happens weekly. Dealership of course cannot find any issues or replicate codes....very convenient. Bought new-2023 Jeep Wagoneer Series 2 Hurricane twin-turbo engine.
The thermostat suddenly failed, causing extensive engine failure. The engine failure was the direct and unavoidable consequence of a known manufacturer defect explicitly covered under Customer Satisfaction Notification 26B and TSB 09-006-25 / RSU 25-047 which should have replaced my thermostat or been a recall.
I am writing to formally submit a dangerous and sudden electrical system failure on my 2024 Jeep Wagoneer. I purchased this vehicle brand new from Lee Jeep in Wilson, NC and it currently has only 38,000 miles - just 2,000 miles past the standard factory bumper-to-bumper warranty. This issue represents a severe safety hazard and appears to be a direct, consequential chain reaction resulting from a dealer-performed service and software flash completed just 1,000 miles ago. Chronology of Events: 37,000 Miles: The...

vehicle's thermostat failed. Lee Jeep replaced the thermostat and performed a required computer system software update. 38,000 Miles: Immediately following these updates, the vehicle began completely shutting down and stalling at stoplights and stop signs. Simultaneously, the Electric Power Steering (EPS) completely cut out, leaving me stranded in active traffic with heavy, unassisted steering. Current Status: The dealership diagnosed a blown main engine fuse and is demanding $450 to replace it. They have refused to cover this under a goodwill adjustment, claiming their local branch "cannot do it." A full vehicle shutdown and loss of power steering at intersections puts my life and the lives of my passengers at immediate risk. Unresolved Root Cause: A high-amperage engine fuse does not blow without an underlying cause. I am deeply concerned that charging $450 to swap a fuse without diagnosing the systemic current spike - likely tied to the recent software update or the auxiliary stop-start battery logic - will leave me stranded again. Proximity to Warranty: Given that the vehicle is a 2024 model and barely past the 36,000-mile mark, a catastrophic electrical failure of this nature should be covered by the manufacturer.
Highway shaking, car stalling when in idle, vehicle wouldn't shutoff, steering wheel locked, vehicle wouldn't start, electrical issues: screen shutdown, error messages,
I recently had an oil change at the dealership I purchased the Wagoneer from. Three days after the oil change was completed, I was sitting at a stop light when the vehicle completely shut down, and the power steering went out. I started the vehicle back up and a power steering service notice popped up. That same day, the large central display screen kept flashing on and off, when it finally shut completely off. Six days later, I was driving home from work when I noticed the engine kept running up into the 6-7000...

RPM's if I tried to drive over 40mph. I drove under 40mph the rest of the way home (about 10 minutes) and started noticing how loud the engine sounded and the temperature gauge was increasing. I was about 1 minute from home when my daughter and I could feel the heat coming from the engine inside the cab of the vehicle. It was so hot, I was concerned the vehicle was going to catch on fire. I parked it away from my home and called the dealership. They sent a tow truck and inspected it the next day. They stated the engine thermostat went out, and the auxiliary battery failed. There were never any warning lamps or messages displayed while this was happening. If I would not have been paying attention to the gauges and would have been further away from home, this vehicle could have overheated completely and potentially caught on fire putting my kids, myself, and others on the highway in danger. There was a Campaign Reference: 26B issued by Stellantis in April 2025 stating this exact issue and noting the repair to be performed, however, they only included specific Wagoneer's equipped with a 3.0L GMET6 engine. My engine is a 3.0L I6 Hurricane and was not included in the campaign, even though it is the exact same issue and this could have all been avoided.
While driving my vehicle suddenly shuts off the engine and puts the vehicle into park. This has happened multiple times now and once on I-66 while merging onto I-495. This seems very dangerous.
To Whom It May Concern, I am writing to report a serious safety concern involving my Jeep Wagoneer. The vehicle has experienced intermittent stalling issues, creating a hazardous driving situation and leaving me stranded. The vehicle unexpectedly stalled, causing a loss of power and leaving me without reliable transportation. Given the potential safety risks associated with a vehicle stalling while in operation, I am extremely concerned about the possibility of this occurring again, particularly in traffic or at...

highway speeds. Adding to my frustration, after contacting the dealership for assistance, I was informed that it would be approximately eight days before the vehicle could even be inspected. A delay of this length for a vehicle experiencing a potentially dangerous drivability and safety issue is unacceptable and leaves me without confidence in the safety and reliability of the vehicle. I am requesting that this matter be investigated promptly and that appropriate action be taken to address the stalling condition. I also believe this issue warrants review for any potential broader safety concerns affecting other Jeep Wagoneer owners. Please document this complaint and advise me regarding any available assistance, escalation options, or known remedies related to this condition. Thank you for your attention to this matter. I look forward to your prompt response.

The car was stuck in the intersection causing a threat to life and well-being of those not only in the Wagoneer but to the other drivers as the car could not be moved until towed. This took over an 1.5 hours to get towed and traffic had to be diverted by police.
I have taken my vehicle in several times to get it checked out regarding an issue i have been having since the beginning of the year. I have a severe, recurring engine-stalling safety defect. The vehicle has been in the shop in Boerne texas several times. The engine completly dies, requiring a full manual key/button cycle to restart in/out of traffic. It cuts the power steering and forces the vehicle into park, these are safety issues since at times i sit in traffic for two hours or when i have my newborn grandson traveling with me when i have to travel out of city.
Our vehicle was purchased in December of 2025. Aprox. One month after purchase the vehicle unexpectedly turns off while driving. Fails to start. Along with multiple other issues. Its has been in the shop over the course of that time more than four months and is in the shop current day 14sept2026. We have spend roughly $10,000 to date and continue to be financially and emotionally ravaged. Sealants has been no help. The purchasing dealership also refuses to make it right.
Within less than 24 hours of picking the vehicle up from the thermostat repair on XXX6, it began shutting off on its own and losing engine RPM, including while being driven on the freeway and while stopped at a red light. It shut off completely on its own two times in the first 24 hours back in my possession, with no warning that the vehicle was about to lose power. Losing power on the freeway risks a sudden loss of motive power at highway speed and a high-speed collision, and shutting off at a red light risks...

being unable to move out of an intersection or accelerate away from a hazard, with a heightened risk of being struck. During these failures the vehicle displayed a battery warning code and, separately, a "service transmission" warning; both appeared and then cleared. These symptoms first appeared on [redacted], within hours of the vehicle being returned from the prior repair. The failures have not yet been reproduced by a service center; the vehicle is scheduled to return to the place of purchase, Grogans Town Dodge Jeep Ram on [redacted] for diagnosis, and the same vehicle was in this dealership's service department of another dealership 2 hours from our home because thats where we were when the thermomstat issue occured on [redacted] for the separate cooling-system failure. The vehicle is available for inspection on request. Mileage: approximately 78,000. VIN: [[redacted]].
