The main problem is getting in touch with a real person...There are no greeting messages on voicemail to let you know who you are leaving a message for after the operator transfers your call. I left several messages on what I assume was my service managers voicemail throughout the 2 day service ordeal, which never got returned. I reached voice mail instead of a real person nearly every time I tried to contact the service department, including the cashier, and never got a return call. The shuttle took almost 2 hours to come pick me up (My guess is that he wasn't told to come get me). I had 2 meetings that I missed while I was waiting....After an hour, I called and left a voicemail for the both the service manager and the cashier asking about the driver...no return call....After another half hour I called back and finally spoke to a real person at the cashier desk. They were able to get the shuttle to me within a half hour. Also I don't like the explanation I received as to why my Silverado is making clunking noises in the rear end. I was told it is normal wear and tear on the leaf springs causing creaking noises. I reiterated that it is not a creaking noise, but a real "clunk" as if something is loose. I believe there is something wrong in the rear end, and if it is normal wear and tear causing this, then I have a problem with Chevrolet design and will never purchase another GM vehicle. I've been a GM/Chevy person for 40 years and this was the worst service experience I've ever had.
