2010 Initial Quality Study Results
2010 GMC Sierra LD 1500

Overview
The GMC Sierra is a traditional full-size pickup truck. Like all large American pickup trucks, the Sierra features a highly configurable body-on-frame design with a solid rear axle. GMC offers a wide range of choices in cabs, beds, drivelines, and engines (gasoline and hybrid gasoline-electric power) for the Sierra.
History/Genealogy
GM has been manufacturing pickup trucks since 1930, but it didn't use the "Sierra" name for its full-size offering until about a decade ago; instead it was simply known as the "1500 Short Bed" or "1500 Long Bed." The modern "Sierra" debuted in 1999 on GM's "GMT800" platform. In addition to its role as a commercial vehicle, the platform was to be shared with other models such as the GMC Suburban, Chevrolet Silverado, GMC Yukon, Cadillac Escalade, and more.
The current-generation Sierra was introduced in 2007. The platform, called the "GMT900," features an updated frame, suspension, a new interior, and new exterior sheetmetal. Consumers are offered a choice between 6-cylinder and 8-cylinder engines (gasoline and hybrid).
