A Buyer’s Guide to the 2012 GMC Sierra

The 2012 GMC Sierra may not have sold quite as well as the Ford F-150, but that doesn’t mean you should dismiss this rugged and reliable model. For one thing, the Sierra is available in a half-ton version (1500) or in heavier-duty versions (2500, 3500), and it has performed well in all classes. Also, unlike Ford, GMC also offers the Sierra in a hybrid model, as well. If you’re looking for a half-ton truck that will get the job done and give you the comfort and amenities you want, consider the Sierra.

Key Features

Heated and cooled front seats are usually reserved for luxury sedans, but GMC has included them as an option for the SLT trims and standard for the Denali trim. In addition to more comfort in winter and summer, the 2012 GMC Sierra also offers active fuel management for its 5.3-liter V8 models, giving you better fuel economy when you’re driving around town and don't need full engine power.

Changes for 2012

In 2012, GMC added more stability to the Sierra with trailer sway control and hill start assist. The Denali trims also gained a rearview camera, as well.

What We Like

Whether you’re looking for a very basic truck for work or you want to feel like you’re driving a luxury vehicle whenever you leave the house, GMC offers a trim level for you. And, if a compact pickup truck won’t do the job, you can choose the Sierra 2500 or 3500, too.

What Concerns Us

Even the smaller 2012 GMC Sierra 1500 is still a pretty big truck, and it could be too big for a lot of drivers’ needs. If you’re looking for an around-town truck, this might not be the best model choice.

Available Models

The 2012 GMC Sierra 1500 is available in your choice of a 4.3-liter V6 engine or three V8 engines, ranging form 4.8 liters to 6.2 liters. The V6 boasts 195 horsepower at 4600 RPM and 260 lb-ft of torque at 2800 RPM, with a fuel economy rating of 15 MPG in the city and 20 MPG on the highway. As you go up in engine size, horsepower and torque increase, but fuel efficiency decreases.

Major Recalls

Some models have been recalled due to a potential transfer pump failure, which could cause the engine to stall. A few others have been recalled because their ignition lock actuators may have binding issues.

Common Issues

A very reliable vehicle, the few complaints about the 2012 GMC Sierra seem to center around issues with the stabilizer and tracker failing.

Chevrolet Impala V6-3.6L - Pre-purchase Car Inspection - Lansdale, Pennsylvania
Shawn was prompt, professional, and delivered the promised service as expected. This was a used vehicle pre-purchase inspection. Shawn also had to drive to multiple locations to perform the inspection, as the address listed that I provided him with was not accurate, but he still made it to the correct location within his time window and completed the inspection.
Toyota Sequoia - Pre-purchase Car Inspection - Akron, Pennsylvania
Shawn was very prompt in communicating with me and was good at helping me decide whether to purchase a used car. He help me avoid a car with a repaired rusted frame that could be a danger to my family's safety since we were planning on using the car to tow a travel trailer!

Acura RDX - Pre-purchase Car Inspection - South Hackensack, New Jersey
Luis did a thorough pre-purchase inspection for me, and found several major issues that made me pass on buying the car. Had I purchased the car, I almost certainly would have ended up paying thousands in repairs down the road. Thanks Luis!

He did a pre-purchase inspection for me. He was knowledgeable and fast, and knew what he was looking for. I really appreciate all the pictures and documentation he took of the state of the car before purchase. He noted potential issues with the car that I wouldn't have been able to notice. Would recommend.

I trust Robert. He gave me a list and we will take care of it the week of June 29. I will know then that my vehicle is ready for the winter and is safe to drive. I look forward to getting things ready for another winter of careful driving.
