Owner reports

Selected complaints filed with NHTSA by 2025 Jeep Wagoneer S owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2025 Jeep Wagoneer S. The contact stated that while driving approximately 25 MPH, the vehicle failed to accelerate and stalled. An unknown service warning light was illuminated. The contact pulled over to the side of the road, turned off the vehicle and the vehicle was able to be restarted. On another occasion, while the vehicle was parked at the residence, the vehicle lost power, and the contact was locked inside the vehicle and was unable to open the doors. The vehicle was towed to a dealer, where it was diagnosed and it was determined that a software update was needed. The software update was completed; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 1,000.

I am reporting ongoing, unresolved, and potentially dangerous issues with my [Year] Jeep [Model, Trim], related to the ECU, electrical system, and overall drivability. I just picked up the vehicle yesterday after it spent 31 days in service, during which the dealership pulled over 65 different codes. Despite this, the vehicle was returned to me with no true resolution, and within 24 hours of driving it again, it is now showing 23 additional new codes. The car has stalled while driving, creating an extremely unsafe situation. On several occasions, it refuses to start. At one point, the vehicle was stuck in drive for over 27 hours, making it unusable and unmovable. These issues are recurring and unpredictable, making the vehicle a clear safety hazard. I've contacted Jeep Customer Care repeatedly. My assigned case manager refuses to respond, and they will not assign me a new one. …

While traveling on the interstate at approximately 70 mph, I pressed the accelerator pedal to increase speed. Instead of accelerating, the vehicle suddenly jerked, and the wheels locked up as though the brakes engaged on their own. I continued pressing the accelerator, but the vehicle rapidly decelerated without responding to throttle input. The most concerning part was that the brake lights did not illuminate while the vehicle slowed down, which created an extreme safety hazard because drivers behind me had no warning that I was slowing. A large truck traveling directly behind me nearly collided with my vehicle because the sudden deceleration was not signaled by the brake lights. This incident placed both myself and surrounding drivers in immediate danger. The vehicle is currently at the dealership service department for inspection, and I have reported this issue. …

Just bought my vehicle and already had to have it towed into the dealer because it would not charge. They did some updates and sent it home. I charged my car fully. Drove it 3 miles and parked. When I came back out to my car 30 minutes later it turned onI put it on reverse but it would not drive and all of the letters on the gear shift were lit up red and a bunch of warnings were flashing on the vehicle to service transmission. The "red lobster" or red wrench was illuminated as well as multiple other things. The car would not turn off as it kept stating it was not in park. Could not turn it off, could not drive it and then it finally went dark after an hour and I could not even get to the batter as the back hatch is connected to the battery that was dead. I had to have my car towed again!!! Second time within a month of owning the vehicle. …

The dealership claims it was a software issue on September 9, 2025, and then it happened again on September 22, 2025. I shut off the car like they told me and I went on my way then it happened again on September 29 this time it was worse. The car literally stopped, and I injured both of my legs with my son in the car. He banged his knees on the passenger side. I notified the dealership Bayside and they picked up the car this morning at 6:50 AM they claim they are changing the part that I charged the car. They're waiting for another part dealership claims they are taking apart from a new car and putting it in this car this jeep Wagner S is a danger to me and my family. It is not fair to feel unsafe driving this vehicle, this is a safety issue exchanging parts from other vehicles is not the solution. …

On [redacted], my 2025 Jeep Wagoneer S (VIN: [redacted] ) suffered a sudden and complete electrical and transmission failure while I was driving my child to school. Without warning, multiple system error messages appeared, the transmission locked, and the vehicle became totally unresponsive. It would not shut off despite several attempts. The wheels were locked solid, and the tow operators had to use sliding skates under the tires to load it onto a flatbed truck. The dealer (Castle Chrysler Dodge Jeep Ram of Naperville, IL) confirmed this condition is a known manufacturer defect under Service Publication [redacted], and explicitly stated that "there is not a fix for this condition at this time." This event created a serious safety hazard - had it occurred on a highway, it could have caused a catastrophic accident. …

Was driving on a side street when the following warnings appeared: "Stop Safely - Vehicle Will Shut Off Soon", "Service Electric Vehicle System" , Wrench warning light. Immediately attempted to pull to the side of the road. Once stopped, the vehicle completely froze and became inoperable. The vehicle had to be towed to Shaver Chrysler Dodge Jeep RAM in Thousand Oaks, California.The same safety-related failures are being reported not only in the Jeep Wagoneer S, but also in the Dodge Charger Daytona, which shares the same STLA Large EV platform/These warnings on the Wagoneer S and Charger EVs indicate a critical fault detected in the vehicle's high-voltage or 12-volt electrical system, frequently stemming from a software glitch, a loose 12V terminal, or communication errors between the battery control modules. . …

The most recent occurrence happened on January 20, 2026. This was not the first time this issue occurred. During a prior incident involving the same loss of accelerator response and unpredictable vehicle behavior, my small children were passengers in the vehicle and became visibly distressed and worried. During the most recent incident on January 21, 2026, while driving through an intersection, the vehicle entered a reduced power or "limp mode" condition and would not accelerate when the accelerator pedal was pressed. When the accelerator pedal was released, the vehicle accelerated unexpectedly and rapidly. Warning indicators related to electronic stability control and the high-voltage system were present. Diagnostic information later indicated loss of communication with the high-voltage battery systems. The vehicle behavior was unpredictable and felt unsafe. …

The vehicle has experienced two critical drivetrain failures. The first occurred in December 2025 at approximately 2,000 miles. The transmission failed, leaving the vehicle undriveable and requiring a tow. After repair, the vehicle was returned still displaying brake-system service warnings and had to go back to the dealer a second time. The second failure occurred on March 23, 2026 at 3,471 miles. The instrument cluster displayed 'Service Transmission' and 'Service Transmission - Set Park Brake to Prevent Rolling' with multiple red warning indicators. Battery was at 47%, confirming this is not a charge issue. The vehicle lost all drivetrain function without warning and could not be driven. This is a safety-critical defect - complete loss of propulsion and the inability to hold the vehicle in gear creates a risk of the vehicle rolling and a stranding hazard. …

Right after purchasing the Wagoneer S, a big red sign and a red wrench showed up on the dash, saying electrical issues. It happened every day. The car stopped in the middle of the road and did not want to move until I shut it off and turned it on again. Sitting in the garage the car would not go into gear, just had all the lights flash. Restarted and all worked. Took to dealer, they had it two days and told me they did not have a fix for the electrical issue. Took it home and 2 days later same issues. Called the dealer again and took it back to the dealer. It has been sitting at the dealership for the last 35 days. Called Wagoneer, Stellantis and the new Jeep in Detroit. No help. Parts issues. I looked at a Wagoneer group on the internet, a large number are having the same issues and more. …
