Sadly we longer have this vehicle due to a very bad accident. We were sandwiched between two other vehicles at a stop light. Our 2012 GMC did everything it was expected to from a safety standpoint and saved us from sustaining much worse injuries. Thank you GM for a great product...

I love my little work truck, short bed, 4.3 engine. Why? Because I paid 15,900 for it minus a 750 dollar USAA rebate. It's my third new GMC/Chevy in 10 years and I expect it to be as reliable as the previous trucks.
A joke

I have bought 8 new GM trucks over the years and the last 3 have been A Joke....the 2012 GMC Sierra being the biggest joke, truck looks good but here is a list of issues after 65000 miles... Transmission shifting issues, down shifting Rear end clunking, slack in gear train Noisey cab, Noisey bed, Noisey breaks 2 set of breaks in 65000 miles???????? Battery replacement after 40000 miles??? Using oil after 50000 miles.... Warranty covers nothing, GM said this is normal of a truck with that many miles 😉 Biggest piece of junk I have ever owned.... And I've owned several F150's so I'm qualified!!!

I have had this truck since November of 2012 with 15 miles on the odometer. Currently I have 209,000 miles and some change. I have had to recently change the tire rods, hub and bearings on the front. Talking with my mechanic, he is not surprised with the amount of miles that are on this truck. The engine runs great and I have never had a problem with the engine running full synthetic oil since my ownership. Full Synthetic is a little pricier but I feel it has paid off. The transmission does shift a little hard from time to time when accelerating, but I have never had to repaire. The drivers side bed at the top of the wheel well is starting to bubble with rust, but in all fairness it was replaced after owning the truck for 16 months when a contractor backed into it with his trailer. Other than that no surface rust. I am hoping to get a few more years or another 100,000 miles from this vehicle.
