Adaptive Cruise Control problems of the 2025 Jeep Grand Cherokee

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.

My 2025 Jeep Grand Cherokee 4xe began with an intense burning smell followed by the “service hybrid electric vehicle” warning light illuminating. After this, the vehicle experienced numerous electrical issues with the infotainment system, and the air conditioning failed. At one point, both the service and battery lights came on and the car lost all power, would not shift from park, and could not move. The service light continued to illuminate a total of eight times. During the seventh and eighth occurrences, the vehicle became unsafe: once while stopped, the electric and motor systems appeared to fight for power, and the next time while traveling around 55 mph, the car suddenly lost power and rapidly decelerated, creating a serious risk of a rear-end collision. This problem has been reproduced by the dealership, who attempted to replace the module control module without success. Dealership and myself contacted the manufacturer and were told there is currently no fix and to “hang tight” until one is available. Due to the severity and ongoing nature of the issue, I have also filed a claim with ncds USA for further support.
