I have been driving this truck for almost 2 years, so I know all of its little nuances. Unfortunately, I am not impressed. I have had many GM vehicles and this has been one of the worst. Warranty issues include: new radiator, new brake rotors, power seat motor, tranny problems, etc. I can only attribute this stuff to the fact that GM is rabidly seeking the cheapest suppliers on the globe, which has to hurt quality. I must admit that I use my truck heavily, but what good is a pickup truck that can't handle a little beating? Considering the msrp on this thing was around $39000, GMC must do better with its 2007 model. If not, Tundra and Titan will have Sierra for lunch!
Good suspension and 4wd
Overall build and materials quality is not up to industry standards.
