2012 GMC Sierra 1500 Interior

This interior review was created when the car was new. Some links may no longer point to an active page.

Regardless of the model you choose, reviewers say you’ll find that the 2012 GMC Sierra 1500 has spacious and comfortable seats. But many shoppers will be disappointed when they look at the base Sierra’s minimalist interior, which looks uninspiring and has little storage. The Sierra does offer tech features and interior cubbies, but only with trim upgrades, which means you’ll pay more.

  • "On the whole, the Sierra's interior fit and finish ranks highly, though base models tend to look rather dull compared to their rivals.” -- Edmunds
  • "GMC makes a lot of noise about the Sierra's ‘pure pickup’ interior touches, which feature larger controls and handles designed to operate easier with gloves. The base trim level is a bit on the bland side, but if you want better amenities, you can step up to the SLT or Denali trims.” -- Automobile Magazine
  • “Standard ‘Pure Pickup’ interior materials are better than expected on a work-oriented truck, but are not extraordinary by absolute standards. Luxury and Denali interiors up the ante, even though most surfaces are hard plastic.” -- Consumer Guide


The 2012 GMC Sierra seats between three and six people, depending on the configuration. Vinyl seats are standard, though cloth is a no-cost option. Leather seats are standard on SLT and Denali trims. When it comes to comfort, reviewers are quite pleased with the Sierra’s seats. They say they are firm, comfortable and provide plenty room for adults, especially in the crew cab’s back seat. Extended cabs have a back row that’s a bit more cramped, however.

  • “Ample room for adults. Both the bucket and bench seats lack side support in fast turns but are firm and comfortable.” -- Consumer Guide (front seats)
  • “Factor in comfortable seats - at least in the upper trim levels - and the Sierra earns our endorsement as a long-distance road-tripper.” -- Edmunds
  • "Cab space up front is generous, but Extended Cab models offer somewhat cramped rear seating. If you plan on carrying your crew in comfort, the Crew Cab's theatre-style elevated rear seats are the way to go.” -- Kelley Blue Book

Interior Features

Like most pickup trucks, base models don’t come with many standard interior features. The Work Truck trim comes with manual air conditioning, an AM/FM radio, cruise control and 12-volt power outlets. However, since the Sierra comes in so many trim levels, by the time you get all the way up to the Denali trim, it can be outfitted to near-luxury levels. The GMC Sierra 1500 Denali comes standard with features like a Bose sound system, remote start, power-adjustable pedals and a heated, leather-wrapped steering wheel.

Reviewers say the GMC Sierra’s controls are fairly easy to use.

  • "The gauges are easy to see and read. Sierra's Pure Pickup interior places radio and climate controls high on the dashboard, just out of easy reach. … The optional navigation system absorbs some audio controls but doesn't complicate their use." -- Consumer Guide
  • "The pricey SLT and Denali trims dress up the cabin significantly, with a unique upscale dash and door panel treatment, a full center console and attractive wood grain and metallic accents." -- Edmunds


Reviewers say the Sierra 1500 has an average amount of cubbies and other storage for small items. If you plan to carry around a lot of gear with you in the cab of your truck, you’ll want to opt for an extended or crew cab model, since regular cabs have very little space behind the bench seats. One test driver notes that although the Sierra’s high bed walls mean it can carry more cargo, it also makes it harder to reach the center of the bed.

  • "Interior storage is merely adequate, with small cupholders and haphazard organization for the center console.” -- Edmunds
  • "The 2012 GMC Sierra 1500 truck features a large box area with high walls to maximize cargo capacity, although this same design can make it difficult to reach the center of the bed, as is required when accessing a bed-mounted tool box.” -- Kelley Blue Book
