I loved my '08, and it was somewhat unique, being a stick, so I didn't really want to replace it. It spent 4 1/2 months in the shop during the first year, and even then I kept hoping it would finally work. Then the ignition switch failed while I was trying to catch a flight, and that was it. My service manager started the process with the GM rep, and I didn't have to do a thing. 3 1/2 weeks later, I was in my new CTS-V, which has been MUCH better. The hardest part was transferring the GMAC loan from the '08 to the '09, but the dealer even ferried the paperwork to me so I was inconvenienced as little as possible. The buy-back saved me $15,700 over a trade, so I'm pretty happy. As this occurred seven weeks ago, they were in the process of arranging their bankruptcy, yet I didn't have to threaten anything, or get a lawyer, or do anything but wait a bit. I have another friend who had a GMC Acadia with HVAC problems that couldn't be fixed, and he had no problems getting a replacement, either, though this was a year ago. I hope your process goes as cleanly, but my experience was very positive.
