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.

Mercedes-Benz SLK280 - Pre-purchase Car Inspection - Laguna Hills, California
I hired Chris to inspect a car I wanted to purchase. He arrived on time and gave me a very detailed report, took the time to call me after to review details, and share his impression of the car. He was great and very knowledgeable, I would highly recommend him!
Lexus IS250 - Pre-purchase Car Inspection - Irvine, California
Smooth experience, was able to communicate succinctly and arrived early to the appointment. Thoroughly completed the 50-point check and gave me his professional opinion. His report on the vehicle reflected knowledge on the vehicle, along with giving me his own estimate on the pricing. Definitely helped me with my purchase.

Honda CR-V - Pre-purchase Car Inspection - Flushing, New York
Jason was great, prompt, and extremely helpful! He explained every aspect of his concerns with the car and answered all our questions in detail. Since I don't know much about cars, it was amazing to have someone who explained how things work in a simple but well rounded way. We are so appreciative of his help!

Jason came on time, explained the procedure and immediately started the pre-purchase inspection on my 2012 Dodge Charger. Very thorough, very knowledgeable! I’ll be using YourMechanic for the suggested maintenance and repairs.

Anderson was great! I was unsure about my purchase because of the year and the condition. Anderson's inspection really put everything into perspective. Thank you!
Land Rover LR4 - Pre-purchase Car Inspection - Little Neck, New York
Anderson is amazing! A previous mechanic was no-call/no-show through this site when I was at the dealership, so I was skeptical of the service. However, but I'm glad I gave it another go and Anderson came through the next day! HUGE thanks to him for arriving early, being thorough, and most importantly, communicating with me as I was not able to be in-person for the inspection. Thank you, Anderson!

Professional. Couldn’t be there to inspect with him and gave me a full detail inspection and his honest opinion ( which I asked for ) did an amazing job.
