I only have 1100 miles on my truck and it already has major problems! I've been into the dealership several times and they say theres nothing they can do and GM won't do anything either. The interior is CHEAP, the climate control has electrical problems, the truck leans noticibly to one side,& the transmission has major issues. It clunks & slams into gear like a 20 yr old truck. The leather has more defects than I can count. I am very sorry I bought this truck. I feel like I am stuck with a lemon.
The XM radio and sound system are nice.
At 9-10 mpg, gas mileage could be better. Transmission issues need to be worked out (dealer said its a common complaint)and electronic problems with climate control need to be corrected. (My previous GM product had problems with climate control also-guess its an ongoing problem).
