Took my 2016 Sierra with 52k on it, to the GMC dealership a week and a half ago for a check engine light, slight emissions leak, per my scan tool. They put a new valve assy. on it and with labor was around $520. Check engine light came on yesterday. Same issue on my scanner. Obviously not fixed. Did they change out a properly working part?? Who knows. What do shops/dealerships do in this instance?
Going back in Thursday morning to be looked at again.
