My service appointment was on 5/19 at 3pm. Services scheduled to be performed was a 125-point vehicle inspection and oil change on my 2013 Corvette GS. When I got off the freeway and turned the corner to arrive at the dealership, my exhaust started making this horrendous rattling sound. I had just that morning had a Borla Atak catback exhaust system installed, so I requested they take a look at that to see what would be causing the noise. The service manager, Deniz Dalgic, looked at me as if I were crazy. The service department closes at 5pm and the service tech leaves at 4pm. He could not possibly diagnose the rattling sound... I guess the 125-point inspection does not count known issues causing a rattling sound. He was sorry, but I will have to take that back to the exhaust people who did the install. The reason that I was getting these services done was that I had just purchased the vehicle at had it shipped from a dealership in GA. I was in need of this inspection/oil change to purchase a GMEPP contract. So, when the service was finished at 4:15pm I asked for a printout of the inspection report to send in for the GMEPP. Deniz said the service tech had already left and he was not able to access the computer records. So, I asked if he could email me a copy of the report on Monday. He said that if he could not figure out how to email it, that he would send it snail mail. Here it is, June 2 and I have still yet to receive anything.
Well, on Monday I took the 'Vette to the exhaust shop to have them take a look at it. Once they had it on the lift they could see one of the bolts on the mounting bracket had worked its way loose from heat expansion. The exhaust had shifted back about 1/2" and was rubbing against the rear mount point. They moved the exhaust back into place, tightened the clamp and put a small tack weld on the joints to make sure they do not come loose again. Problem solved, in less than 20-min!
I guess this means that I will be looking for another dealership to perform services in the future.
