2012 GMC Sierra HD Interior

This interior review was written when the 2012 GMC Sierra HD was new.

Test drivers say that the GMC Sierra HD’s interior is fairly roomy and its features are easy to use, though a few mention that the materials and design feel a bit out-of-date. Other trucks may have more high-tech options or more luxurious interiors, but reviewers feel that the inside of the Sierra HD is solid, sturdy and functional, and in Denali trim, fairly luxurious.

  • "The matte finish may be dull and uninteresting, but this is a work truck first and foremost, and the space and ergonomics don't offer anything to complain about.” -- Autoblog
  • "Cabin materials are solid and sturdy overall, though there is plenty of hard plastic. The interior ambiance ascends from bare-bones functional in the WT trim level to upscale passenger-car pleasant in the SLT and Denali. Unique trim pieces give Denali a distinct character.” -- Consumer Guide
  • "More significantly, the interiors are essentially the same as those introduced on GM's trucks four years ago. While functionality is roughly equal, the other guys -- most notably Ford -- have moved ahead on the cabin environment. The previously unavailable Denali trim helps, but only at the top price.” -- Popular Mechanics

Seating

The GMC Sierra HD can seat up to six, depending on the cabin configuration. Some reviewers find that filling all six seats with adults can make the cabin a bit cramped, but it’s plenty spacious otherwise. The front seats are available in bucket (which brings the seating capacity to five) or bench styles, and the back seat in extended and crew cabs is available only as a bench. Reviewers don’t say much about the seats, but the few who mention them say they’re comfortable. One writer mentions that Ford’s and Ram’s crew cab models offer more spacious back-seat accommodations, and another says that the back bench seat is uncomfortable.

  • "The crew cab interior is spacious enough for four or five adults, and the leather-trimmed seats offer good comfort over long distances.” -- Automobile Magazine (2011)
  • "Beyond the quiet, the crew cab was exactly that, with second-row seat room big enough to accommodate three adults in comfort.” -- Autoblog (2011)
  • "The front seats are quite comfortable, though some drivers might find the driving position a bit awkward because of the tilt-only steering wheel (it's too close to the dash) and gas and brake pedals that are far apart in order to accommodate work boots. “ -- Edmunds
  • "Headroom is generous in both extended cabs and crew cabs. Legroom is ample in crew cabs, but tight in extendeds with the front seat more than halfway back. Extended-cab seats have an uncomfortably upright backrest; crew cab's backrest is set at a more comfortable angle. As in front, high step-in complicates entry and exit.” -- Consumer Guide

Interior Features

Like most heavy-duty trucks, the GMC Sierra HD offers an interior that ranges from Spartan work truck to luxurious hauler. The base WT trim comes standard with basic features like air conditioning and an AM/FM radio, while top-of-the-line Denali models offer luxury features like leather-appointed heated and cooled seats, dual-zone automatic climate control and a rearview camera. To check out all of the standard and optional features on a particular trim, see the full list of 2012 GMC Sierra HD specs.

While the Sierra HD can be outfitted with features that will be comfortable enough for daily commutes and meet requirements at the job site, shoppers should keep in mind that other heavy-duty truck manufacturers offer better interiors. The Ford Work Solutions system that’s available on Ford’s Super Duty pickups can keep track of your tools, your crew and can even keep track of your fleet of trucks. If you’re looking for an even more upscale interior, try the Ram Heavy Duty Laramie and Laramie Limited models. Some reviewers say that these Laramie models are the most luxurious of all heavy-duty pickups, with a standard heated steering wheel, remote start, power chrome heated mirrors with memory positioning and even heated rear seats.

  • "Gauges are clearly marked and well-lit. Controls are straightforward and most are within easy reach. The available navigation system is intuitive and simple to use.” -- Consumer Guide
  • "We're also not particularly fond of the small and finicky buttons on the higher trim's center stack.” -- Edmunds

Cargo

Most automakers, including GMC, don’t list formal interior cargo volume dimensions. Those who need the most in-cab storage will want to look at a crew or extended cab, as regular cabs have very little space behind the seats. Most reviewers mention that there are plenty of cubbies for Sierra HD owners to store cell phones, MP3 players and other small items, though one says that cabin storage is just adequate.

  • "Small-items storage is ample overall and varies somewhat by model and equipment. Some have dual gloveboxes and dual door-mounted cupholders. Bucket-seat Sierras have a gigantic center-console bin; bench-seat models have handy partitioned console storage in the fold-down center backrest. Rear seat-bottom cushions fold up for additional cargo versatility.” -- Consumer Guide
  • “A variety of useful compartments provides out-of-sight storage for everything from work gloves to laptops.” -- Kelley Blue Book
  • “Mediocre cabin storage.” -- Edmunds
