On 7/16/2026 exactly 1 week after i purchase the vehicle after fueling i drove about 1 mile when the car started to misfire, when attempting to accelerate. Check engine light flashes a few times and then went off. I then attempted to reverse into my driveway and when attempting to do so the vehicle shut off completely. But started right back up. I then called the dealership and was asked to bring it in. The dealership has the vehicle about 2 days and said it has been repaired it had bad spark plugs. When to get the car it drove fine with no issues until 7/28/2026 when i made an attempt to drive to work, i had driven about a mile from my home and car to a red light when the light turned green i attempted to accelerate and the vehicle was hesitate. Then a few warning lights came on that showed issues with electronic throttle control and electronic stability system service. …
I am reporting a serious safety concern with my 2026 Jeep Grand Cherokee L. On multiple occasions, while driving and needing to slow down quickly behind another vehicle, the vehicle has emitted an audible warning, the engine has shut off while the vehicle was still moving, and the "D" drive indicator began flashing. When this occurs, the vehicle loses propulsion and I am only able to coast to a stop. I then have to place the vehicle in Park and restart the engine before the transmission will operate normally again. This has happened more than once and appears to occur during firm or rapid braking/deceleration. The braking was not an emergency stop or collision. The vehicle simply required quicker-than-normal deceleration due to traffic ahead. …

I was driving on the highway on 9/23/2026 at approximately 5pm CST. A disabled vehicle ahead warning flashed on the dash and I experienced sudden, unprompted high RPM surges while driving. My car started making a very loud engine sound and I could smell something burning. I could not surpass about 20 MPH. I put on my hazard lights immediately and pulled off the highway and drove to a safe space. My safety and others were put at severe risk because my car immediately slowed to 20MPH on a highway at rush hour. I could have been rear-ended and severely hurt at the speed cars behind me were traveling. Others in the cars behind me could have been badly hurt as well. I couldn't get initial assistance from the dealership despite trying to contact them repeatedly and talk to a live person and instead kept being transferred to a virtual chatbot. …
