Overview & Reviews

The pickup truck has long been a mainstay of American byways and highways, and GMC has been there from day one. Originally used and respected by farmers, construction workers and small-business owners, GMC's hauler was a basic workhorse known for its reliability and longevity. More recent times have seen GMC's full-size truck adopt the name Sierra. And thanks to a variety of body styles, powertrains and trim levels, the Sierra is as adept at serving as the weekday family car as it is at transporting home-improvement supplies or towing a boat on the weekends.

Older versions of the GMC Sierra 1500 pickup have been praised for their strong work ethic, but soundly criticized for their bland, cheap cabins. With the newer generations, however, fit and finish is notably better. Of course, there are other choices in the full-size pickup truck market, but the Sierra 1500 remains a solid pick no matter what the intended use.

Current GMC Sierra 1500
Redesigned for 2014, the latest GMC Sierra 1500 is both trimmer and stronger than before. The V6-powered regular cab truck, for example, is about 250 pounds lighter this year while the engine lineup, particularly the V6, benefits from higher output and efficiency. Other changes for the new Sierra 1500 include revised suspension tuning for a smoother ride, forward-hinged rear doors on extended cab models and newly available safety features.

This full-size pickup is offered in regular cab, extended (double) cab and crew cab body styles with various bed lengths. Trim levels consist of base, well-equipped SLE, luxurious SLT and off-road-oriented Z71, and there is a choice of either two- or four-wheel drive.

All but the SLT come standard with a 4.3-liter V6 that makes 285 horsepower and 305 pound-feet of torque, enough muscle to tow up to 7,200 pounds. The 5.3-liter V8 (standard on the SLT and optional on other Sierras) makes 355 hp and 383 lb-ft of torque. Both engines come matched to a six-speed automatic transmission.

The new V6 is vastly superior to the old V6, not only in terms of power and performance but also refinement. Of course, the 5.3-liter V8 delivers strong acceleration as long as you're not shy about laying onto the gas pedal when needed -- it has a rather lazy response otherwise. The six-speed automatic provides smooth and timely shifts and the Sierra 1500's towing performance is commendable.

Overall ride and handling dynamics are solid, as the GMC Sierra 1500 feels robust structurally, yet compliant and comfortable over broken pavement. Models fitted with the Max Trailering package, however, have a noticeably stiffer ride that can grow tiresome. The newest Sierra is also very quiet, even at higher freeway speeds. On serpentine roads, the GMC goes around turns in a confident manner and its steering is well-weighted. Off road, the Sierra similarly feels composed.

Used GMC Sierra 1500 Models
The previous-generation GMC Sierra 1500 was produced from 2007 through 2013. There were three body styles (regular, extended and crew cabs), and trim levels ranged from no-frills "Work Truck" to ultra-plush Denali.

Powertrain choices through these years encompassed everything from an anemic 4.3-liter 195-hp V6 to a muscular 6.2-liter V8 with 403 hp. Most Sierras, however, were fitted with either a 295-hp 4.8-liter V8 or a 315-hp 5.3-liter V8. A four-speed automatic was initially standard across the board except on the Denali's 6.2-liter V8, which came with a six-speed unit. Eventually, the six-speed was fitted to the 5.3-liter V8 as well. Either rear- or four-wheel drive could be specified.

Calling cards of this GMC Sierra 1500 include strong performance, a refined and quiet ride (even with the heavy-duty towing package) and a comfortable, sensible cabin. The Denali was certainly plush, though it still didn't have the same space or high-end ambience of its Ford and Ram top-of-the-line rivals. Other potential downsides included minor ergonomic missteps and the hesitant downshifts of the four-speed automatic transmission. We had no such gripe with the excellent six-speed automatic, however, thanks to its smooth and on-point performance.

Potential buyers should be aware of the significant changes made throughout the years. For 2009, the Denali's 6.2-liter, 403-hp V8 with its excellent six-speed automatic became optional on select other trims. That year also saw the debut of Bluetooth, a back-up camera option that didn't require the optional navigation system, and the "XFE" (extra fuel economy) package for the crew cab. The following year, 2010, saw the 5.3-liter V8 get the six-speed transmission and variable valve timing, which both improved fuel economy slightly. The 6.0-liter V8 (367 hp and 375 lb-ft) that had been offered since 2007 was dropped that year while side curtain airbags, front seat side airbags and stability control all became standard across the board. Lastly, USB connectivity (standard on Denali) became optional on the SLE and SLT. For 2012, the navigation system was updated (now hard-drive-based) and trailer sway control joined the safety features list.

Before this was the popular 1999-2006 generation of the Sierra. Underneath the conservatively handsome styling, a family of new V8s debuted, ranging in size from 4.8 to 6.0 liters. They offered output ranging from 255 hp with the smallest 4.8-liter, to 345 hp from the high-output 6.0-liter V8 in the Sierra Denali. A base V6 was also available, but as expected, most Sierras came fitted with one of the V8s. A unique four-wheel-steering option (called QuadraSteer), debuted about midway through this generation and cut the truck's turning circle down significantly to 37.4 feet -- around 10 feet less than a typical full-size pickup – making U-turns and maneuvering in tight spots much easier . Unfortunately, QuadraSteer was discontinued for 2006 due to a low take rate, as buyers were put off by the high cost of this option.

Consumers more interested in function than flash should be happy with a half-ton Sierra from this era. The truck offered plenty of performance and work capacity, but was hampered by a dated cabin design fraught with cheap materials and below-average fit and finish.

The previous generation of GMC Sierra 1500 pickups ran from 1988-'98. Standard cab and extended cab body styles were offered, as was a crew cab, though the latter was actually from the previous 1981-'87 generation. Although six-cylinder and diesel V8s were offered, chances are strong that most GMC trucks from these years will have either a 5.0- or 5.7-liter V8 mated to a four-speed automatic. In keeping with tradition, one could choose either rear-wheel drive (indicated by a "C", e.g. "C1500") or four-wheel drive (indicated by a "K"). Trim levels for these C/K1500 trucks include the bare-bones Special, base SL, midlevel SLE and top-line SLT. Strengths of these trucks include powerful, durable powertrains, while weaknesses center on sketchy build quality and subpar materials within the cabin.

  No complaints - Great truck - 2007 GMC Sierra 1500
  By Brad - June 15 - 11:03 pm

  I looked forward to this truck arriving and havent been disappointed. I like everything about my truck. Size, handling, performance. I am in the process of customizing the truck and theres not a lot I have to do. From four wheeling in the snow to pulling a large trailer to zipping down the highway, this trucks got getup and control. The only complaint I have is that the bottm half of the fuel tank disappears in a hurry, but for a 5.3 its not all that bad. So far Ive only experienced minor adjustments.

  GMC Sierra Denali - 2004 GMC Sierra 1500
  By RR924 - June 10 - 10:00 am

  I knew I had to get a truck, but I wasnt all that excited about it. Weve always had them, but I had always driven a large sedan or SUV. I was amazed at what came standard on the Denali. This trucks standard equipment has all the luxury of the SUVs plus all of the utility of a full-size truck with 325hp, full time 4WD and Quadrasteer. The handling and performance of this truck is better than any other truck Ive driven. The Denali is excellent in highway and city traffic as well as being very easy to get into and out of tight spaces. People stop me on the street and in parking lots to talk about this truck, thats never happend to me before.

  1 heck of a truck - 1999 GMC Sierra 1500
  By william mcduffie - May 31 - 7:43 pm

  All I can say is "awesome". This is the 1st truck that I have owned and I dont regret it at all. Ive never had a 325 5.3 v8 before and I love it. It has sweet gas mileage for a v8. I can go 470 miles on a full tank of 93 octane. Horsepower, oh my God, its unreal. It has the power of a 400 c.i. v8. I truly love this motor. Thank you GM for this V8.

  Texas Truck - 2009 GMC Sierra 1500
  By Sam - May 14 - 12:06 pm

  First new pickup in many years, always had a used one around, but primary vehicle has been SUVs until now. This truck has the Z71 off road pkg and the towing pkg that includes the 5.3L/6A upgrade. Overall, the ride is good but the seats are not very comfortable for long rides. Iyt seems to have good power even towing a heavy load. Fuel economy could be better, but I only have 4500 miles on it so that might improve some. I average 15 mpg with 17 being my best highway trip so far. On the down side, it has a light rattle in the A/C vent that I cant pinpoint, but varies with fan speed and the rock chip protectors on the fenders are peeling off. But overall, it seems to be a good vehicle.

  My Last GM product - 2006 GMC Sierra 1500
  By wdh2 - May 8 - 6:07 am

  I bought this truck used with 50K miles; GMC certified + factory warranty remaining for 10K more miles. I have had lots of problems out of this truck. In less than 5 months of ownership; -the center console shorted out -the rear brakes locked up and burned up the rear-end which had to be replaced (not covered under warranty) -Lots of vibration in front end- the front end came loose from the truck and had to be re-welded -Power steering kept cutting off when turning (frayed line attributed to the front end separation) -Short in heated seats -Tail gate had to be replaced and now the new one will not open (dealer installed) -Transmission is now slipping This truck has only seen pavement

  Some mechanical problems - 2000 GMC Sierra 1500
  By gmfan - May 5 - 6:06 pm

  I am surprised to see so many positive reviews on this vehicle. True, it is fun to drive and has a good ride and great stereo, there have been several disappointing mechanical problems. It seems to chew through brake pads in about 10000 miles. This problem was worse before the recall work on the anti-lock brakes that I am surprised no one else has commented on. Also, the rear tailgate is about to rust off and a brake line has rusted through leading to a brake fluid loss and near braking disaster. Also, numerous squeaks and noises that are undiagnosable.

  Aint what she used be - 2008 GMC Sierra 1500
  By jst0771 - May 1 - 1:46 pm

  Bought in July of 08, currently have 65K on the truck. the only gripe I really have about is a major one. The powertrain. Im not a hard driver, mileage has been mostly highway. Ive had the forward sprag gear brak in the transmission, a front wheel bearing start to come apart, and now its sitting in the service department for low oil pressure. It also is down 2.5 quarts of oil with 25% life left on the monitor and no low oil level indicator. Ive been told by the service department that the engine can burn a quart every 1000 to 2000 miles and be considered normal. Ive reviewed several forums on the issue, and there are alot of people with with the same issue, being told the same thing.
