On Saturday morning after pulling out of a parking space my car stalled and lost power steering. I put it in park and restarted engine it was fine. Went to other store, parked it and the same thing happened once I returned to leave. When I got home I shut off the ignition switch and after app. 8 seconds I heard a sound coming from behind the fuse box area or at least behind that area . Sounded electrical "vooop, vooop" I also noticed when going up an incline around 30 mph the car had a huge delay, I had to push the gas pedal practically to the floor, and than it kicked in and zoomed off. I felt like I was loosing power and than the car took off on its own! crazy feeling!!! I feel as though the computer that is in charge of the car is out of wrack and the car has become inconsistent to drive because of what could occur next. I also lost brakes this winter while driving due to brake booster failure which eventually became a recall. I was scared then and I'm afraid this incident may result in something bigger and worse. :(.
The vehicle would crank multiples time before starting. Three or four times, the car shut down while driving; it finally came down to the fuel pump not shutting down after the ignition switch was turned off, and the only way to shut down the fuel pump was to pull the fuse out of the ecm unit in the engine compartment. I was charged $1200 dollars for a new ecm unit at the dealer but the new unit was defective and needed the wire harness to be rewired due to an internal problem inside the ecm unit (the left fog light would blink instead of the front blinker light).
