There are 4 owner-reported driver assist & adas complaints for the 2018 Chrysler Pacificain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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))
FORWARD COLLISION AVOIDANCE SYSTEM CAME TO A COMPLETE STOP AT A CHECK POINT PROCEEDED FORWARD WHEN TOLD TO AND WITH IN 20-30 FEET THE WARNING SYSTEM WENT OFF AND VEHICLE CAME TO AN ABRUPT STOP FOR NO REASON. NOTHING IN FRONT OF THE VEHICLE AT ALL. SIMILAR SITUATIONS HAVE HAPPENED BUT THERE WERE VEHICLES PARKED ON THE SIDE OF THE ROAD AS YOU GO INTO A TURN, BUT THE VEHICLE NEVER ACTUALLY BRAKED FOR THOSE.
MY NEW PACIFICA IS EQUIPPED FOR THE FORWARD COLLISION WARNING SYSTEM. THIS IS ONE OF THE BIG REASONS I CHANGED TO THIS EXACT VAN. WELL, IT DOESN'T WORK. I HAVE TRIED TO GET IT TO ENGAGE, NO WARNINGS, NO BRAKING, NO ANYTHING. I HAVE HAD IT IN THE DEALERSHIP AND THEY CLAIM THEY TRIED IT AND IT WORKED BUT THE SERVICE GUY REFUSED TO DO IT AGAIN BECAUSE IT WASN'T SAFE. UMMM, ISN'T THAT THE WHOLE PURPOSE OF IT? IT IS SET TO THE FARTHEST DISTANCE SETTING AND NOT WORKING. I HAVE HAD TO SLAM ON THE BRAKES WHEN TESTING IT, SO KNOW THAT IT IS NOT WORKING. THE DEALER IS GIVING ME THE RUN AROUND BUT I HAVE READ THAT MANY OTHERS HAVE THE SAME ISSUE. THIS NEEDS TO WORK! I PAID EXTRA FOR THIS PACKAGE AND AM VERY DISAPPOINTED. A NEW 45000 VAN THAT DOESN'T DO WHAT IT IS SUPPOSE TO IS RIDICULOUS.
TL* THE CONTACT OWNS A 2018 CHRYSLER PACIFICA. WHILE DRIVING 60 MPH AND APPROACHING A VEHICLE, THE FORWARD COLLISION WARNING SYSTEM FAILED TO ALERT. THE VEHICLE WAS TAKEN TO HUNTINGTON JEEP CHRYSLER DODGE RAM (1220 E JERICHO TURNPIKE, NY 11743, (631) 673-0270) WHERE THE SENSOR WAS RECALCULATED. THE REPAIR DID NOT CORRECT THE FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND DID NOT ASSIST. THE APPROXIMATE FAILURE MILEAGE WAS 810. *TT UPDATED 9/26/18*JB
