My Service Rep, Luciano Rotondo I have dealt with since 2017. That involved my late 2017 Acadia purchased there and my present 2018 Acadia bought used elsewhere. On my visits for service he has always kept me updated on the status of my vehicle whether I chose to stay at the dealership or go home. I know some repairs take more time than others. Additional problems that have cropped up, he has always called me, detailing them and the costs involved. Overall he has an excellent rating in my opinion.
