My vehicle slips out of gear while in traffic and leave me coasting with the engine racing. This happens every time it is driven.
Transmission slips out of gear during normal city driving. I have had the car completely lock up, become unable to drive, and needed to be towed to the dealership. This is the 3rd time I have encountered this issue. I've had the transmission computer restarted, one of the clutches replaced, then a few months after that had the car towed to the dealership again due to "immobilizer malfunction" design for the car is great but the mechanics are terrible.
