NHTSA Complaint #11549065 — 2017 CHRYSLER PACIFICA

While driving vehicle, car shifted to neutral then park then neutral, while in drive moving down road. Numerous warning came on including "service shifter", check engine, front end collision sensor, abs brake sensor, along with a message to put car in park before shifting . The day before a warning of service shifter came on and the car was unable for a few minutes to shift out of park. Then the codes suddenly went off. Took it to auto zone to check codes and it said no codes were found or stored. First time was September 25, 2023. The next time when it shifted itself out of drive while driving was September 28. Drove home from getting checked for codes with nothing showing up. Drove 5 minutes on October 2, and a bunch of random codes flashed. Took to shop and they found no codes. All warnings went off. Said nothing anyone could find wrong. Said nothing showing up and was fine to drive. October 5 was driving home, 526 miles later with no warnings , and suddenly stopped driving while in motion on road. Same codes flashed. Shifter stopped working. Car wouldnt start or shift. Completely broke down. Had to be towed to dealership. They say transmission needs to be replaced and it is only 500 miles out of warranty. The same 500 miles we had to drive to get it to throw codes. Had previously taken in when I thought transmission was problem when it was dropping gears. They said software update. Continued dropping gears after they "fixed it" and when I called they said it had to relearn how I drove. Almost had 2 major accidents now when it stopped completely on its own while driving.
