2006 GMC Sierra 1500 SL1 4dr Extended Cab 4WD 8 ft. LB (5.3L 8cyl 4A)


Initially had a few Q.C. issues with the speakers blowing, weather seal falling off, passenger arm rest detaching and the rear brake light assembly falling off, the real fun began. at 57k the tranny blew. Shortly after the transfer case failed. At 70k the drive side wheel bearing failed. 6 months later same bearing failed. At 75k the rotors replaced for 2nd time. Solenoid on gas tank replaced. Steering shaft knuckle replaced. Truck quivers and rattles over the smallest of bumps after 79k miles. Forgot to mention the rust on rocker panels, doors and wheel wells.

The truck is such a lemon my kids make fun of it.

Best Features

Would same the 5.3L V-8 but it rattles like a diesel on cold starts. Even after switching to Mobile 1 synthetic at 25k
