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

The transmission fails constantly when we are accelerating - approxx 50-58 miles per hour the transmission freezes & the RMP's stay @ 4-5 thousand for 20-30 seconds - it fails to downshift. This is extremely dangerous at any time & can cause a major accident if the vehicle is stuck & you need to stop! We have have left the car several times for this issue & they keep telling us they cannot replicate the issue. (We are older & we are given looks like we are nuts)

The contact owns a 2025 Jeep Grand Cherokee. The contact stated that they had just purchased the vehicle brand new with the intent to utilize the Forward collision Warning plus avoidance system, The contact stated that on various occasions while driving the Forward collision Warning plus avoidance system will not function as proposed and no warning lights will illuminate. The vehicle was taken to a local dealer where the vehicle was diagnosed and the contact was advised that the front bumper sensors and Forward facing camera were faulty and needed to be replaced. The components recommended were replaced however the failure persisted. The manufacturer was notified of the failure. The failure mileage was 3,000.

The contact owns a 2025 Jeep Grand Cherokee. The contact stated that while operating the vehicle, the message "Auto Emergency Braking Limited - Service Required" was displayed with an audible chime. Additionally, the cruise control became inoperable. The vehicle was taken to the local dealer, who reprogrammed the CADM. After retrieving the vehicle, the failure reoccurred. The vehicle was not repaired. The manufacturer was not yet contacted. The failure mileage was 4,800.

Subject: Forward Collision Warning Plus and Advanced Brake Assist Failure – 2025 Jeep Grand Cherokee Laredo I am reporting a safety defect involving the Full-Speed Forward Collision Warning Plus and Advanced Brake Assist systems on my 2025 Jeep Grand Cherokee Laredo. The vehicle does not provide forward collision warnings or apply assistive braking in situations where a collision is imminent. On multiple occasions, a vehicle in front of me slowed or stopped while turning into a driveway or parking lot. My Jeep provided no visual alert, no audible warning, and no braking assistance. I had to manually brake to avoid rear‑ending the other vehicles. I brought the vehicle to the dealership. During testing, the system could not be activated on my Jeep. We then tested another Jeep of the same model and year; its system also failed to activate until we were within approximately three feet of the vehicle ahead. My Jeep never activated at any distance. The dealership stated that because Adaptive Cruise Control slows the vehicle when active, the collision warning and brake assist systems must also be functioning. This explanation is inconsistent with how these systems are designed to operate, and it does not address the failure of the Forward Collision Warning Plus system to activate in real‑world or controlled conditions. This appears to be a systemic failure of the collision‑avoidance technology on this model, creating a significant risk of rear‑end collisions.

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.

*The AEB light comes on saying Limited Functionality Service required. We have Taken it to the dealer and they service department said no codes for that problem showed up and said if it did it again pull into any dealership and have them check it. It happens constantly so it happened right when in front of one of their dealership so we pulled in and they checked again and it did come up showing an electrical issue. They saw our pictures I was continuing to take of the dash showing how often it comes up. So I did just that and had a photo book, the size of a wedding album showing how it went off sometimes every two hours. *Then the lane depart doesn't work, it will not vibrate, which we have all the settings on and set to the highest setting. *The warning for cross traffic when in reverse doesn't always work sometimes it won't even go off when someone walks close to the back of vehicle. * On just a few occasion the rear door will not close when button is pushed, we have to physically close it. *Sometimes it will continually slam on the breaks when we try to back out of our garage, taken several times of me putting in park and trying again. *Also sometimes when backing out it won't drive when I put in drive, I have to put in park, then move it to drive. *It is currently in the dealership, they have had it for 4 days and cannot figure it out but acknowledge it is happening.

On multiple occasions now, my shifter starts blinking at me and the dash tells me to shift into park and then shift into desired gear. This is quite annoying is baffling and dangerous. Also, on multiple occasions the dash lights up it goes crazy beeping like crazy like it wants me to stop and there’s nothing in front of me for me to need to stop. This could be potentially very dangerous. I see others have had issues like this as well so I think we really need to do something about this for somebody does get hurt cause it locks up it doesn’t let you go anywhere until you put it in park and put it in gear Not safe

Traveling at around 55 MPH, slowed down for a stop light. Dash started flashing and beeping and stated "shift to park then shift to desired gear." Could not accelerate, had to put in park then back in drive to keep moving. No check engine light. 2 dealerships cannot fix because there's no code. Seems to be a common occurrence on Jeep forums. Afraid this will happen again on the interstate and I will get rear ended or not be able to get off the road. Major safety concern!
