Lou Fusz Buick GMC

I went to dealership for routine oil change, tire rotation and multi-point inspection. While there I also mentioned to service advisor that the check engine light has recently come on and subsequently gone off over the past week of so. She recommened an engine diagnostic be performed to determine to source, stating it could be a minor issue relating to the oil change or some major power train problem. It turned out the problem was cause by a loose timing belt and other internal engine issues all of which were still under warranty. The problem was fixed within a couple of days saving me thousands of dollars had it not been discovered until later. The dealership paying for a rental car while mine was being repaired was a much needed extra bonus. Thanks Lou Fus
