Engine light has gone on repeatedly for the last few months. Mechanics have told us each time that the gas cap was loose. So we purchased a new gas cap from Chevy and replaced it. The engine light came on again still. We are taking it in for servicing now. Very frustrating. Will update later.
Had to replace due to failed inspection
