Very disappointed.
I've been very disappointed in this vehicle, and GM in general. GM didn't stand behind the expensive extended warranty we purchased, and I've had to have extensive engine work done on a vehicle with only 60 thousand miles on it. The dealership seems to enjoy providing bad customer service, and not care about bad remarks made to the Better Business Bureau.
It's a comfortable truck, and the cd player/radio sounds great.
But, after 40 plus years of driving GM vehicles they've lost me as a customer. I would urge everyone to avoid their products.
