I think that the GM should fix this problem for free i have heard it happen to many other vehicles in my area. It is a nice vehicle but maybe they should look into there engines and stand behind them...

Valve in the number 2 cylinder is shot. My vehicle has been at the dealership since 5 Dec 05, and now it's 9 Jan 06. I'm still waiting on it to get fixed, they've been saying the delay has been waiting on parts, I could've had a new engine put in by now. After the repair it'll most likely happen again, so I'll be trading off real soon before the warranty expires. In fact, this is real close to be considered a "lemon" under lemon laws since they've had it for over 30 consecutive days. Hmmmm!!
