U joints were bad when I bought it from the dealer.
Manual seat adjuster knob was broken when I bought it from the dealer.
Transmission went out at 62000 miles.
Wipers worked intermittently at 63000 miles. (very dangerous)
Dash illumination stopped working at 63000 miles (fuses okay)
There was a squeak that drove me crazy near the rear left speaker... had to rip off the plastic covering and stuff insulation in... fixed the problem.
Hood wouldn't close... had to rip off plastic that it was rubbing against.
Clutch went out at 68000 miles on the interstate.
The dealer was absolutely terrible. didn't return calls, took forever to repair, lied, etc.
The truck looks nice and it is a comfortable ride, but the mechanical problems caused me a great deal of stress and about $1500 in repairs in the 9 months that I've owned this money pit. Stay away from this vehicle.
I will never buy GM again.
Sounds like whoever got rid of that truck before you got it knew what they were doing.
