Adaptive Cruise Control problems of the 2018 Chrysler Pacifica

Electrical adaptive, cruise control, forward collision warning, and shifter all malfunctioned. It is available for inspection. There was failure to accelerate at an intersection which almost caused vehicle to be rear ended. The error codes have been pulled and shown by o’reillys auto parts. The vehicle is pending inspection by an independent mechanic. The adaptive cruise control the Ford collision, warning and service shifter warning lamps all appeared shortly before this problem occurred.

Van was working fine one day and the next, before I even started it, when I pressed the brake pedal to start the van, there was a buzzing noise from the braking system and pedal went almost to the floor. Once I started the vehicle, the noise stopped and the pedal travel returned to normal. However at the same time, the warning light / message for several of the systems came up (abs, traction control, collision detection, parking sensors, etc) along with several messages (parksense unavailable, fcw unavailable service required, service antilock brake system, service electronic stability system). Using an obdii code reader displayed several "communication errors" (start with the letter "u"). I researched it on the internet and it would appear that this is caused by a common failure of the "star connector" ("bus module" to connect various components in the van). I ordered a replacement part (which I haven't received yet) but not completely surprisingly, about 1 week after the issue occurred, today my vehicle was running properly with no more errors. I'm hoping NHTSA forces fca to fix this issue under a recall. I've read of several other owners suffering the same issue and imo, this is a security risk as abs and traction contol (along with other systems) are disabled when this happens. In included pictures of the dash when it happened (note all the warning lights) and of the dash when if fixed itself (no warning light although mil is still on (I haven't cleared it)).

Recurrent intermittent power steering failure and intermittent engine stall. Steering wheel gets stuck when turning right while driving at speed on highway. Steering wheel gets very heavy and requires some force to get it back to center. If I let go of the steering wheel, it would stay in the same position until I move it back. When driving at slower speeds, usually when navigating around turns or roundabouts, the engine will stall and then drastically jolt into gear. Two different mechanics have not been able to identify the root cause. They have checked alignment, electrical codes, and other potential issues without any answers. After research, I believe I am experiencing similar issues as detailed in the safety recall v53 / NHTSA 19v-348 power steering assist. My VIN was not included in the recall , but I believe my car is showing similar concerns. I have requested a local Chrysler dealer look into this issue specifically and I have an upcoming appointment.

Car was on cruise control. While approaching traffic, attempt was made to release cruise control by braking. Brake system was locked, vehicle started accelerating and revving. Brakes would not work, had to swerve to avoid collision. Managed to fidget with the gear knob. Finally managed to gain control of vehicle. I figured I gained control because I must have shifted the gear into neutral somehow. I had my entire family of six in the car. Without having gained control, the vehicle would have accelerated until I crashed it. It accelerated past 80mph before I could gain control.

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.

Honestly it’s been one thing after another, including engine, power train and electric issues.

Hi, I received a recall notice in February 2022 (z11) related to a fire potentially originating in the center of the vehicle underbody with the ignition in the off position. A resolution to this defect has just become available which would require the car (Chrysler Pacifica VIN 118706) to be kept overnight by an authorized dealer. My complaint deals with that no deal can provide a rental car that is of equal size to accommodate my family of 6 with four kids using car seats. I was told that an car of equal size cannot be provided and would have to pay for a rental out of pocket. Why would the cost not be covered by the manufacture that is attempting to resolve an issue created by them. I have kept my part of the agreement by making my monthly car payments and paying the car off with no issue. It seems to me that the manufacture has no regard to the buyers of their vehicles after the sell is complete. I am looking to have the recall corrected and to have a rental car of equal size provided by the manufacture, since they are holding my car as they fix their mistake. Let's take ownership of our mistake and do the right thing. Thank you for helping with this recall.
