NHTSA Complaint #11422166 — 2013 DODGE DART

06/08/2021. My daughter stopped to gas up at Costco when a notice came up on the dash "Engage Parking Brake to prevent Rollback". She immediately called me to make me aware of it. Once home she again get this message. 06/09/2021. My daughter drove to school with no issues. However, leaving school she was going slowly over a speed bump when the car automatically shifted into PARK. She lost acceleration and the car rolled backwards off of the speed bump while she was wrestling with controlling the steering. The car shuts off and she was unable to start it again. She immediately called me and told me the message displayed again from yesterday "Engage Parking Brake to prevent Rollback". Now the car won't start. I am now on my way to the school when she calls me back to say it started and she is on her way home. I told her to be very careful. 06/10/2021. I drove the car while my daughter followed me to the dealership. On the way to the dealership at every stop the message displayed "Engage Parking Brake to prevent Rollback". While at the dealership I explained the problem and I had brought all repair documents that stated the same issue occurred in a repair with my son (twice), with me, and now with my daughter. It all stem from gear shift cable/bushings/TCM/transmission, which then was covered under warranty or recall. I emphatically didn't want to waste time with a diagnostic when I am sure its related to past repairs. The service tech was trying to convince me it could be something else and the diagnostics will tell them the true cause. I was reluctant but agreed for the diagnostic. I did state that what that diagnostic will show is that the transmission/recall is faulty. 06/11/21. The service tech called me to say the car coded P07B4 [Park Positioning Sensor]. However he never called it a Transmission Park Positioning Sensor because in my opinion this part should be covered under the transmission warranty (see Manual - Parts Covered - Transmission:).
