On multiple occasions my vehicle has not recognized the key fob when I have been at the vehicle. I have actually been standing by it trying to open the door and it would not respond. Even if I was holding the key fob in my hand next to the door it would not respond. I would have to manually push the unlock button on the fob to be able to enter. This has caused me personal safety concerns when in unfavorable situations and I could not immediately gain access to the interior of my vehicle. The memor seat and easy exit functions have repeatedly failed to operate as they should causing me to be out of position when driving requiring manual resetting of the position. The heads up display consistently shows the incorrect speed limit. Google Maps and Carplay intermittently become disconnected while I am driving creating a safety hazard when I am using Google Maps guidance. The date below is simply the most recent time these happened. Again, these have happened repeatedly over the period of ownership.

2024 Jeep Grand Wagoneer L Obsidian. Water intrudes into the left headlight assembly through a defective seal, destroying the LED driver module (OEM part #68590086AD) and burning the internal wiring harness connector. This has caused: (1) complete headlight failure while driving in winter conditions with passengers; (2) sudden loss of engine power while in operation; (3) battery failure with standing water found under the battery on the left side; (4) Uconnect/radio/antenna/telematics failure (case open since 30,000 miles, unresolved). All failures traced to the same left-side water ingress point. Jeep Case #94993514 and Wagoneer Connect Case #94079691 both open and unresolved for 18+ months. Vehicle used for licensed medical patient transportation. Multiple roadside assistance calls. Total losses approximately $10,000.

This issue happened 3 times in a matter of 2 months. All 3 happened in 3 different intersections. While turning left in the intersection (oncoming traffic also turning left) the vehicle jerks to a full stop in the middle of the intersection with a "Crash Detected" message flashing on the dashboard screen. The vehicle stayed in DRIVE and continued to drive after full stop the first 2 incidents. On the 3rd incident, the vehicle stopped completely, and would not continue to drive. The vehicle had to be put into park (even though it said it was in drive but did not drive) and put into drive again to continue moving. Other vehicles driving behind the Grand Wagoneer were required to slam on brakes to prevent impact of the Grand Wagoneer and had to wait for the Grand Wagoneer to begin driving again. Unable to drive this vehicle due to safety issues. The vehicle is currently in the shop under investigation.

I recently purchased the vehicle in May 2025. It was a dealer car from original purchase. One month after purchasing [June 2025] the vehicle the car would not start. I called in roadside assistance to jump start the car. I took the car to a Jeep dealership for servicing. They recommended replacing both batteries. They mentioned one of the batteries were not an original. This must mean the dealer who owned and sold me the vehicle was aware of the battery issue. In late July, little over one month the vehicle would not start. I call for roadside assistance again. I dropped vehicle with dealership. I called two days later, and they could not discover the problem. They suggested I leave the vehicle for up to three weeks. This would give them sufficient time to attempt to discover the cause of the battery drainage. This is the first time I am experiencing any short coming from purchasing a vehicle since I started purchasing cars. I am hoping a resolution has been discovered for the battery drainage issue for the 2024 Grand Wagoneer. I am the owner: [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Multiple battery drainage issues resulting in car not starting and battery going to zero volt. Car running hot. Failed thermostat causing engine overheat and car to shut down. System breaking issues.

Late last year I reported that while towing a trailer, the dash indicated that the trailer had disconnected from the trailer as looking back I noticed the lights were off when the vehicle lights were on. Before I could pull over to check the connection, the lights turned back on and the warning light extinguished. This happened 3 times when towing the trailer that day. The dealership "reprogrammed" the module and said it was good. But after the latest recall for the Wagoneer, having it recalled, I wanted to notify someone about the potential for expanding the vehicles included in the recall.

The vehicle has ongoing electrical and battery system problems that cause safety and driver-assistance systems to malfunction or shut off unexpectedly. The vehicle has repeatedly been found dead after short periods of non-use, requiring jump starts and battery replacement. These electrical issues appear to affect multiple vehicle systems simultaneously. While driving, advanced safety features such as lane departure warning, lane keep assist, adaptive cruise control, and proximity-based warning systems shut off, become unavailable, or behave inconsistently without warning. In some cases, warning messages appear and then clear on their own, while the affected safety systems remain disabled. At other times, the systems deactivate without any clear alert. The manufacturer and dealer have acknowledged battery drain and electrical instability, but instead of permanently repairing the underlying problem, certain features were disabled to reduce battery draw. These include proximity-related features and other driver alerts. Disabling safety and warning systems does not correct the defect and creates an unsafe condition where the driver cannot rely on the vehicle’s advertised safety features to function consistently. Because these systems disable themselves or are intentionally disabled due to unresolved electrical issues, the vehicle cannot be relied upon to provide continuous lane-keeping assistance, collision warnings, or adaptive cruise functions. The failures are unpredictable and occur during normal operation, creating a safety risk to occupants and other drivers.

The vehicle warning indicator lights Electric Power Steering (EPS) fault light comes on and the vehicle becomes hard to steer while driving. The Stop/Start active light, Engine check/ malfunction light, service power steering light comes on and the vehicle shuts down when idling at a traffic light, the engine is automatically placed into park and has to be restarted by the driver. The vehicle is back in the shop for the third time for the same issues.

The contact owns a 2024 Jeep Grand Wagoneer. The contact stated that intermittently, the back-over prevention camera and navigational system froze, the speedometer was blank, and the air conditioner was inoperable. The contact stated that the Uconnect 5 infotainment system was inoperable. The navigational system continued to be frozen and was buffering for an hour at times. The vehicle had shut down on multiple occasions but restarted. The app indicated the vehicle needed to be serviced. The key fob became inoperable; the driver was unable to lock and unlock the vehicle. There were unknown warning lights illuminated. The vehicle was taken to the local dealer, who connected the computer, but there were no codes retrieved, and was unable to duplicate the failure. The vehicle was not repaired. Additionally, the contact sent an email and videos. The manufacturer was contacted, who opened and closed several cases. The failure mileage was approximately 132.
