Oct 2022

While driving on the highway the engine shut down and I needed to pull over and restart the car. The engine would restart but then stalled several more times while driving. No check engine lights were on before the vehicle stalled and upon restarting the car no check engine lights turned on. I have it at the dealership currently but they can't look at it until December because of their backlog of repairs.
