I was driving on the highway and the car stalled. Warning light came on that says, stop safely now. The car completely lost power on the highway. I was lucky because that put me in a dangerous situation. Finally got it towed to the dealership and module-engine control. Pcm get too hot and the ignition switch. The car has been in at the dealership since 10. 14. 20 and has not been fixed and there still is not eta. Part is on backorder. This car has been tag a lemon and it should not be able to be sold. I didn't know this prior to purchasing the vehicle.
