Our ATS had 2 issues. 1st was that the CUE system lit up but did not respond to inputs. 2nd issue was the smell of axle fluid after driving vehicle. Dealer diagnosed both problems at 1st visit but had to order parts. They replaced the entire CUE system and replaced both axle seals and the differential cover gasket since they said it was hard to pinpoint exactly where leak was from. I appreciate that they tried to avoid a repeat visit by replacing all seals at first try. Service Advisor was very good at keeping me informed and explaining the issues to me. I was very happy with this service experience.
