On Friday t after the car sat for approximately 8.5 hours, I started the car to go home. After sitting in the parking space for about 30 seconds to one minute the engine started running very rough like only two cylinders were running. A message saying to service the traction control system came on the center DIC as well as the traction control warning light. The check engine light was also blinking at this point. I left the car run for another 45 seconds too see if any of the lights would go out and they did not. I shut the car off, waited about a minute then started the car again. After restarting the car all the lights were off and the car ran completely normal. During the whole incident the car was sitting in a parking space and was not driven. I called onstar to run a diagnostic on the car and they found nothing. I was advised by a GM customer service rep to have the car checked out.
Today I take it in to get looked at and there telling me that's its due to bad spark plugs. They told me there is a tsb although i could not find it. That when the check engine light comes o the traction control warnings automatically go off. Due to it being spark plugs I was charged $80 to look at it. Is since when do spark plugs stop acting up when you turn the car off and back on?
This was a different dealer than before. I guess I can trust any dealer. And my power train and GM major guard are completely worthless!
i wish I could afford to get rid of this car. Never ever again will I buy a ChevyChevy
