The shift gear has become stuck in park twice. The shifter will not move. I had to have it towed to the mechanic twice in order for the vehicle to become operable again. The shop replaced some wiring and mechanics inside the shift area. Since they have replaced it twice, along with the original parts, I am on the third round.
