2009 Chevrolet Silverado 1500 LT 4dr Crew Cab 4WD 5.8 ft. SB (4.8L 8cyl 4A)
We purchased this truck brand new Oct 2009 with the heavy duty towing package Z71 4x4.
We had to put a new engine in the truck Oct 2010, after that problems continued.
Dec 2010 the throttle body failed as I was driving down the highway, Stablizer, engine light, traction, lights flashed, door locks when crazy and just stopped in the middle of the interstate.
Yesterday 2.17.2013 it proceeded to do it again on the interstate. Second time in 50,000 miles we have had to replace the throttle body on our fairly new truck.
We have other problems including 3 window motors, mirror, rough idling, & transamission rough when switching gears.
All the work has bene done at the dealers
