On August 25, 2026, my 2016 Ram 2500 was parked on private property. The driver states that she placed the automatic transmission in PARK before exiting the vehicle. After she exited, the unoccupied vehicle unexpectedly began rolling and struck a tree, causing vehicle damage. No one was injured. There were no known warning lights or messages indicating a problem before the incident. The cause has not yet been determined and the vehicle has not yet been inspected for this incident. The vehicle is available for inspection. This vehicle is equipped with a steering-column-mounted automatic transmission shifter. I am concerned that the incident may involve the transmission/shift interlock/Park system. I am aware of NHTSA Recall 17V-821 (FCA T79), involving unintended rollaway in certain Ram trucks, as well as NHTSA Recall Query RQ25003 concerning reported BTSI failures in vehicles including Ram 2500 models. The NHTSA VIN lookup currently shows zero unrepaired recalls for this vehicle; however, I do not yet know whether the prior T79 recall repair was performed on this specific vehicle or when it was performed. I did call the dealership and they said possibly 0ctober 3, 2018. I am submitting this complaint because the vehicle rolled after the driver reports placing the transmission in PARK and exiting the vehicle.
