Cruise Control problems of the 2018 Chrysler Pacifica

On even minor declines, the van gains speed well past acceptable limits while cruise control is engaged. I have had to brake to disengage the cruise control when it passes 10 mph over the set speed. My 2011 Chrysler town & country did not have this problem, so not sure why a newer model vehicle does. It does not explicitly accelerate but it does not brake to maintain cruising speeds on even slightly graded downhill slopes. The longer the slope, the worse the effect.

I've had it happen twice now where the cruise control was set to around 64 mph, and when going downhill, the transmission down shifted. However, the car then accelerated beyond 70 mph both times, and didn't let go of the accelerator until I turned the cruise control off.

2018 Chrysler Pacifica limited. Consumer writes in regards to issues with active cruise control (acc). The consumer stated the acc was not reliable if the vehicle was on a slight incline or slight decline relative to the target vehicle. The dash does not show the presence of a vehicle ahead.

I called the dealer regarding another issue with my vehicle. I was told that there are 2 open recalls and had to wait 2 months to get the service appointment. The recalls are for a manual park release and the cruise control. This is very alarming and very dangerous. I called Chrysler corporation and was told that there is nothing that I can do and need to wait the 2 months. This vehicle is a hazard to the road! I do not feel comfortable driving an unsafe vehicle for 2 months!.

My wife and I just purchased the Pacifica and decided to take a road trip from arizona to oregon . While traveling through the hills and mountains the transmission would not shift properly to maintain highway speeds! there was a lot of lag time from the drivers input between the transmission and engine to respond. Also the cruise control would engage suddenly and speed up. Took to the dealership and the tech said the vehicle software was engineered that way and he couldn't do anything for us.

Tl the contact owns a 2018 Chrysler Pacifica. The contact received notification of NHTSA campaign number: 18v332000 (electrical system, vehicle speed control).

July 28, 2018 7:20pm: stopped the car at crosswalk for pedestrians. While car was stationary with my foot on the brake, the engine started to race with increasing force. Fearing that I could not hold it back with the brake, I reached over and shifted the car into neutral, which remedied the situation. Notes: 1) the cruise control was not engaged at the time. 2) the auto stop/start was not engaged (I. E. The blue light was on). This is not the first time that this has happened. July 13, 2018 12:15pm at disney world: I was traveling down an incline toward a stop sign. As I applied my foot on the brake, the engine began to race with increasing force, despite my foot on the brake. As there was no traffic coming, I simply took my foot off of the brake and proceeded through the intersection. The situation seemed to remedy itself. Notes: 1) the cruise control was not engaged at the time. 2) the auto stop/start was not engaged (I. E. The blue light was on). Neither of these events appear to be associated with Chrysler's u64 or u50 recalls, as neither the cruise control nor manual park release were engaged. However, it should be noted that the auto stop/start was not engaged in both situations. Additional observations: on numerous past occasions, when the car did have the auto stop/start feature engaged (I. E. Blue light off), the car would "buck" while going through an intersection (I. E. It would slam into gear). This is one of the reasons why we now disable the auto stop/start.

Active cruise control fails to detect the vehicle in front. It happens at least once a day. Its does not convey confidence on the system.
