I have owned this vehicle from day one. Within the first year I experienced broken door handles, power door module caught fire, broken rear defroster. SInce, I have had 3 ingition switch failures, had to replace all lifters to due poor design. Most recently, the rear hatch plastic cover above window with the center brake light flew off while driving. This was an absolute nightmare of a vehicle and goes to the problems GM has. I bought it because I wanted professional grade. I was so wrong. Also own 2 G5's for my daughters and replaced both engines within the first 3,000 miles. Nice.
Air Compressor in rear jack compartment.
Engine, 5.3L 8 CYlinder has power but the components are failing so fast I cannot keep up. Everything attached to it should be re-manufactured to be "Professional Grade".
