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…

   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.

   I purchased my 2023 Jeep Wagoneer new in March 2023. The vehicle has experienced multiple electrical/electronic safety-related failures. Beginning around Oct. 2024, the digital instrument cluster intermittently failed to load after startup, leaving me without critical information including vehicle speed and fuel level. I photographed this occurring numerous times and repeatedly reported it to the dealer. The cluster was eventually replaced in April 2026. The vehicle has also…

   Pulling from a stop sign across two lanes of traffic into a median, the car shut off and then started back. When it started back there were multiple warning lights. Pulled out onto highway and when coming to the next turn, there were no power brakes. Had to use extreme pressure to slow the vehicle down to a stop. Turned the car off and then back on and most lights went off.

   While driving at low speed, the vehicle suddenly shut down completely without any warning. The engine lost power while I was cruising, causing the vehicle to stop responding. On separate occasions, the vehicle has also shut off while idling. This condition creates a serious safety concern because the vehicle can stall unexpectedly in traffic, increasing the risk of a collision. The issue has occurred multiple times and appears to be happening everytime i drive the vehicle.…

    It seems that when the outside temperature is very warm/hot, when turning the car on or when idling at a traffic light or driving at very low speeds, on occasion the car will abruptly and without warning, shift itself into Park and the emergency brake activates. I took the vehicle in for repair on 10/23/25 and was told there was a "thermostat internal failure" and that the "thermostat assembly" was replaced. I was just recently traveling in Florida ( reside in NY) and the…
