NHTSA Complaint #11484017 — 2018 CHRYSLER PACIFICA

Sept. 12, 2022 - Ever since we have owned this vehicle, we have experienced this issue with the cruise control. Speed increases while driving downhill highways and sometimes on pretty level highways. When I decrease the speed on the controller, it sometimes maintains the speed for several seconds (slow to respond) in order to slow down while coming up behind another vehicle. I therefore need to break or turn off the cruise control. Very unpredictable. Also, speed changes a lot which sounds like shifting gears back and forth while going uphill. I had contacted the dealer originally and was told this is normal. This is ongoing. Happens every time when driving on the highway. Safety concern. The other issue we had experienced while driving on a city street, we got some odd sounds, what sounded like it was coming for the transmission. Like shifting sounds. and on another couple of occasions, we got a kind of (clunk) noise. Not sure…hard to explain. Only happened a few times over the last several months. and was brief. This in not ongoing, but a concern for failure and or safety. No warning lamps or messages
