I gave lower scores on the interior design only because of the seat belts. All GM seat belts are really poorly designed for comfort. Also, all GM vehicles seem to have some kind of electrical problems or "glitches". Otherwise, this is an awesome vehicle with little or no problems. This truck does seem to lose about 1 quart of oil within the first 1,000 miles after each oil change, for some reason. I was told this is normal, however. Even if the synthetic oil is used, it will lose about a quart & needs to be added before next change schedule after about 3,000 miles.
Power! This truck has power and acceleration that makes you feel like you're blasting off from Earth in a rocket. Sweet! Also, I feel very safe in this vehicle. The 4WD is a huge plus in the Michigan winters. This truck will drive through 5 feet of snow like butter.
Seat belts! GM needs to fire the guy who currently designs or supplies the seat belts and get someone that knows what they are doing! For comfort as well as just functioning properly. Especially the front passenger side, it's almost intolerable to wear & keeps you plastered to the seat!
