My first 50,000 owning this truck were great. It drives like a car and works like a truck. However, the brakes started to make noise and vibrate when stopping. I had it serviced and found the entire brake system developed severe rust. The rear brakes did not function and a pad was dragging on the rotor. I had to replace all the brake parts. The job cost me $1800.00. I later check consumer affairs and found this to be a common problem with the new GM tucks.
My favorite feature is dual climate controls. Body style
I would suggest GM to put better quality brake parts on their truck. The rotors should not have rusted and flake off in chucks. Like the old body panel rust.
