2008 GMC Sierra 1500 Denali 4dr Crew Cab 5.8 ft. SB (6.2L 8cyl 6A)
So I've had the truck less than a year. It has only 18k on it. I've had to replace two door lock switches. I've also replaced a leaky oil pan gasket. It's been in the dealership 3 times. When I wash it the door moldings leak for hours.
A little sluggish of the line, but around 35 there is nothing faster.
