While maneuvering in a parking garage and switching between reverse and forward, the engine suddenly and unprompted revved excessively, sounding as though the accelerator pedal was floored. The vehicle forcefully lunged forward against braking pressure into a cement wall, causing front-end damage to the vehicle. Cruise control was completely disabled and no check engine light or warning indicators illuminated on the dashboard. At no time did I feel like I had control over the car. I sustained some contusions. No one was in the vicinity at the time; however, other cars and/or people could have been struck. The vehicle has yet to be examined by anyone although I am in the process of arranging for an autobody repair shop. Prior to this, the car was in its usual state of health without any issues.

2025 JEEP GRAND CHEROKEE – UNINTENDED ACCELERATION, ADAPTIVE CRUISE CONTROL AND UNEXPECTED BRAKING I am reporting multiple intermittent safety-related problems with my 2025 Jeep Grand Cherokee, VIN [XXX], involving Adaptive Cruise Control (ACC), unexpected acceleration, and unexpected braking. While driving on the highway with ACC activated, the vehicle has on multiple occasions behaved unpredictably. When another vehicle enters or cuts into my lane, my Grand Cherokee does not always reduce speed as expected. On some occasions, the vehicle has accelerated even though another vehicle was directly ahead or entering my path. One of these incidents occurred before a collision. I was traveling in my lane with the driver-assistance/ACC system activated when another vehicle crossed into my path. My Jeep continued traveling forward and did not automatically slow or brake sufficiently in response to the vehicle entering my path. When I manually applied the brakes, there was not enough distance remaining to avoid the collision. I have also experienced approximately two incidents on the highway involving unexpected aggressive braking. When I manually touched the brake pedal, the instrument cluster displayed a red warning and the vehicle suddenly applied extremely hard braking. The braking response was substantially more aggressive than the brake input I was providing. In addition, on one occasion while leaving my office at low speed, the vehicle unexpectedly accelerated without my intentionally commanding the acceleration. The Adaptive Cruise Control and driver-assistance system were OFF at the time. This incident is particularly concerning because it occurred independently of ACC operation. The vehicle has been taken to an authorized Jeep dealership and I reported all of these conditions. The dealership advised me that because the problems are intermittent, if they cannot duplicate the condition they cannot determine what repair to perform. They proposed ext INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

While attempting to park my vehicle, it suddenly accelerated on its own, causing the car to move quickly toward a tree and a nearby building. I immediately attempted to stop the vehicle by pressing the brake pedal, but the car continued to accelerate. The engine was roaring, and I even tried using both feet on the brake pedal in an effort to stop the vehicle, but it did not respond. The only way I was able to stop the vehicle was by turning off the engine. Due to the unexpected acceleration and my concern that it could happen again, the vehicle was not safe to drive. A tow truck was called, and the vehicle was transported to a mechanic for inspection.

Vehicle recently had recall 68c completed. Was driving in electric mode on the highway at approximately 55mph. Upon pressing accelerator further to increase speed to pass another vehicle, I lost all electric power and the vehicle lost speed down to 40mph, despite accelerator pedal being pressed to the floor. Approx 3-5 seconds later, gas engine started, revved high, vehicle lunged forward to 65mph, continued to accelerate after releasing accelerator pedal, and was able to be slowed by pressing brake. This same situation was replicated 9 hours later on the same highway. Dealer claims this is "normal operation."
