Adaptive Cruise Control problems of the 2025 Chrysler Pacifica

Adaptive cruise control stops working for no apparent reason flashes forward collision system not working. Will start up again for no reason from 5 to 15 min. Had this problem for some time starting with our 2021 2023 2025 Chrysler pacifies some times you have to stop and restart to get cruise to work . Dealer cant fix.

We were at a complete stop waiting for traffic to go, I had my foot on the brake pedal and the car lunge/revved up and hit the car in front of me. This is the 3rd time this has happened. The first time we were advised it was probably the front-end sensor that were probably covered with ice. We were advised they are very sensitive. The 2nd time it was winter still, so we took the car through the car wash to make sure no ice was built up. We did not get in an accident because traffic started to move. We took the vehicle to the dealership, and they could not find anything wrong with it. Chrysler corp got involved and they sent a 3rd party to check the van and black box. They advised nothing was found on the black box (not even an accident) and their investigators found nothing wrong with the vehicle. No warning messages were reported after the crash. Police were called to the scene and insurance was notified. Our insurance company advised that we should file this on here. There were 3 people in the van besides myself. We had a loaner vehicle for almost 3 months and we cannot get any information or paper work from Chrysler corp regarding the investigation. We were advised the investigation was confidential and proprietary.

On two separate long trips (over 4,000 miles total in recent months), the adaptive cruise control system has failed while driving on the freeway. This is the most dangerous situation I have ever experienced while driving. When the failure occurs: all cruise control and lane-assist buttons become unresponsive. Dynamic cruise control remains engaged. When I press the brake, the vehicle slows—but as soon as I release the brake, it begins accelerating again. There is no way to turn the system off. The first time this happened, I attempted for several miles to reset the system while controlling speed using the brake. I exited the freeway. At a traffic light, when I began to release the brake after stopping, the vehicle accelerated unexpectedly and nearly struck the truck in front of me. With the brake fully depressed, I shifted into neutral. The transmission made a loud clunk as the engine began revving. I then shifted into park, which caused another loud clunk. I turned the vehicle off while sitting in a turn lane, waited a moment, and restarted it. The system appeared to reset, and I was able to continue driving. Approximately two weeks later, while returning from California, I tested the cruise control system again during a long drive. After about three hours, the exact same failure occurred. This time, I recorded video of the incident and have documentation of the malfunction. This system is extremely dangerous in its current state. I paid a significant amount for this vehicle and its safety systems. A failure like this could easily result in a serious accident or loss of life. I do not believe I should be responsible for paying for a vehicle or system that is defective and poses a safety risk. I have video but could not upload it. .

1215 miles . The adaptive cruise control system was acting sketchy. It failed to maintain proper distance and speed between the vehicle in front. We took it into the dealer who said that the sensor had failed on this brand new vehicle and they replaced it on 2/12/2025. After driving the vehicle when we got it back. There does not seem to be much different. The van tends to accelerate extremely quickly only to get behind the vehicle in front sometimes not keeping proper distance with the way it's set, as well as waiting to the last possible moment maybe 2 or 3 car lengths to break which is extremely scary. Sometimes the warning comes up that says break break . Even with the system said it maximum a car cutting in the system is extremely slow to react. This has led to numerous close calls of rear end collision. We took it back to the dealer on 2/24/2025 1802 miles, who said they couldn't find anything wrong.
