When driving down the street my Malibu just shuts down . . I bought a battery and alternator and sensors to fix my car . Put in shop to find out it was the ignition switch. I'm sacred to drive on the highway it might stop and cause an fatal accident . This is a real safety issue that need to be addressed. . Thank you.
Parked the car, came back out and it wouldn't start, though there was power from the battery and the engine acted like it was trying to turn over (indicating that it wasn't the alternator). Had to have car towed. Turned out that the "theft system" (passlock) locked me out. Mechanics "reset" it. It happened again about 10 days later.
