My van on multiple occassion has stalled in the middle of city intersections. While driving my car will have an electrical meltdown. All different warning messages will appear on dash, warning dings will go off, my wipers will go on without me turning them on, when I push the gas it will not drive. On one occasion the car accelerated without pressing the gas or if the gas was pressed it would accelerate more than the pedal was being pressed. All my buttons on my dash including A/C, auto start, back up camera/sensors will not respond. Its as though my car just dies. This occurrence has no common scenario that brings on the malfunction. I 've had times when it malfunctioned weeks apart and this last occurrence it was a year in between occurrences. I was told on a chrysler forum to check my PCM. My batteries have been tested and passed. I currently do not have my aux battery installed as I do not want/like my autostart feature. This accident occurred all 5 times with my aux battery installed. My dealership said "too many electrical parts to check" and "we cant duplicate the problem/get error code to diagnose so take the van back till it happens again and call us while its happening and drive it in". First its unsafe and unpredictable. I have tried getting this fixed and they can't even/wont fix it or buy it back. No lemon law as I am second owner, not purchased new and the problems started happening at 34000 miles right before warranty expired. This vehicle is unsafe and chrysler won't fix it/don't know how. No remedy after 2 years and 6/7 shop visits. I have opened a case with fca twice and they threatened me to pick up vehicle or they would charge me for the rental I had. Others have experienced this. Look at chrysler pacifica and voyager van on facebook.

Vehicle exhibited "unintended acceleration"; the engine and vehicle suddenly accelerated on it's own while making a slow (10 MPH) left hand turn. Vehicle lurched forward and accelerated. Acceleration lasted for a few seconds after I applied the brakes but did stop accelerating at that point. I was able to stop just short of a parked car I was trying to park behind. This is the only time this has happened before or since the incident. Note: I am an ex powertrain calibration engineer so I know unintended acceleration from my previous employment. Also, my foot was not on the gas pedal when the incident happened. And there was no floor mat interference (pedal physically can't reach the floor).

Notes of 2018 chrysler pacifica : on october 24, I purchased a 2018 pacifica limited with 22,000 miles. Drove it home .and turned into my driveway just before my garage. My wife (who was still in the van) said I was too far over and suggested I back up and line up better. I restarted the engine and put the rotator control in reverse. The engine started and I quickly put the car in reverse. Immediately the engine RPM jumped up, the vehicle started roaring backwards. The reverse momentum thru me forward (I still had the seat belt on). It also thru me against the brake and the accelerator. The pacifica roared back off my driveway into our cul de sac, rotated 90 degrees and landed next to my neighbors stone flower bed. The engine then died. The 'auto stop' feature was operational. Very fortunately, there were no cars or people in the drive so no one was hurt. Had they been it would have been disastrous. It was delivered to the body shop . The total damages were $4,500 and took three weeks in the repair shop.. After return I noticed the pacifica still responded with sudden acceleration and jerky shifting, making driving an extremely nervous venture. An internet search revealed other similar events in the pacifica.
