Was driving my car. Got off I-79 to get gas. Got back in my car and it wouldn't start. Had to get a jump. It started. Started driving (about 4 miles) all of a sudden it started making a noise from the motor. It never gave me a warning, no noise or anything before this. It ran perfectly. I'm so disgusted. They're saying almost $5000. 00 with parts and labor with a used motor. The bearing spun, the roller rocker broke off timing chain, and something else. Hmm a used motor. You do know a used motor will fall into that category again!! I took it to the mechanic where it still sits. I upkept the oil before it was due. It has 138,706 miles I never had any problems with this car at all . Gm I hope you do us right because we stood by you and trusted you!.
