2012 GMC Sierra 1500 SL 4dr Extended Cab 4WD 6.5 ft. SB (4.8L 8cyl 4A)
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...

The 5.3L motor and 6 speed HD transmission combo are surprisingly powerful compared to older half- ton trucks I've previously owned. The truck is pretty fast and keeps plenty of power on tap and will pull a tandem trailer loaded 70+MPH with relative ease. It also is Trans. shifting is not the smoothest at all times but you get used to it. This could be from a number of things and I don't think this is necessarily true across the board with these trucks. I have the Z71 version and currently use all- terrain type tires and must say it certainly outperforms my expectations off- road. The 4x4 auto is a nice feature as well. This half ton gets outstanding gas mileage comparative to my older 1500HD and certainly pulls its weight for a 1/2 ton.

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!!!

Will not buy again. Had the 6 speed manual which kept slamming into 6th gear, apparently its a common problem and its considered "normal" only a year later and the door handles started breaking (100 a piece)w/ install and master power switch failed, and all 4 door moldings fell off. These types of problems I can see if they developed 4-5 years down the road, not in 1 year. Not a 2nd time buyer
