I was driving doing almost 50 when it shut off with no warning the steering wheel locked up the brakes were not working. The first time this happened I just let the car coast to a stop, the second time was exactly the same except I put the car in neutral while I still had a good bit of speed and crunk it back up. The car always crank right back up with no problem and drives fine. I've change my fuses and certain lights (low tire, low coolant, check engine)on the dashboard won't go off and I just recently had my car inspected in which it passed.
While stationary and in motion on highway and on city streets when the turn signal isturned on the vehicle shuts off, and when attempting to restart vehicle with turn signals off the electronics flash as if they are connected to flasher relay.
