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.

  UH OH- did they do this to all GMCs? - 2009 GMC Sierra 1500
  By Kevin UPDATE - September 30 - 8:46 pm

  Ok guys, this is my update. I sold my 09 gmc after owning it for 8 months. When I did, it had 17 service records! The clunk and hard shift you have on the transmission was due to a part installed backwards! I had the sounds of rocks in the rolling wheels at slow speeds, and sloshing gasoline sounds when pulling out of the driveway. I was at the dealership so many times I got to know the staff! For appearance sake, the truck was gorgeous, but mechanically, it grew very old very fast. I spoke to a friend who bought a silverado, and he had the same transmission problems. So lets hope theyve fixed it by now! Im buying a Ford next! I didnt even look at them before I bought my gmc. Big mistake! Bad bad!

  So Far So Good - 2008 GMC Sierra 1500
  By kitch - September 28 - 4:00 am

  Just over 1 week of ownership and I can say I am very pleased with the vehicle. Traded in my Titan LE for this. Interior fit, finish and textures is by far the best Ive seen on any truck. Flip up seats in the rear are nice and a necessity (Tundra I test drove didnt have that). Bose stereo is good and Nav seems easy to operate. Not quite as fun to drive as my Titan was, but still decent. Nice rumble from the stock exhaust. 6 speed tranny is smoooooth. Nice and quiet at 60mph. The AWD is a nice feature to have.

  Pleased - 2002 GMC Sierra 1500
  By Sparky - September 23 - 1:50 am

  Though the vehicle had to have the front differential replaced at 9400 miles, I still would buy another in a second. Absolutely fantastic for pulling my 30 foot travel trailer, excellent fit and finish, and the 4 wheel steering makes it easy to drive and park even in Denvers hectic traffic. Mileage is average, but seating and comfort features are way above average. This is the nicest truck I have ever owned. Leased it originally, then bought it at the end of the lease. Dealer was dying to get it back, but I wouldnt give it up!

  Driving in Comfort - 2012 GMC Sierra 1500
  By tomerikac - September 8 - 11:05 pm

  I drove full size pickups for over 25 years then, due to marriage, started driving small cars/minivans for 5 years. Upon retirement, decided to go back to a full size pickup. Found this two yr. old 2012 ext. cab. 5.3l, 6-speed, 20" wheels, chromed out, tonneau, dual exhaust, bed liner, led lights, 16k miles for only $22.9k. Bought it from a 70 yr. old retiree. True, we would all love better gas mileage, but now that Im retired and driving less miles per year, I love driving this truck. Has been trouble free and very dependable. My young kids love it, too. Im hoping to drive this thing off into the sunset, or until my wife/kids tell me that Im just too old to drive.

  Nice ride - 2000 GMC Sierra 1500
  By j byrd - September 4 - 12:03 am

  I love my truck, it has everything. The only problem Ive had is the power window motors have both gone out and been replaced, and the 4 wd switch goes out and causes message board to read service 4 wd. Seems to be common problem according to dealer and other c/k 1500 owners. Other than that no problems. Gas mileage is not bad for the size of the truck. I figure 18 to 20 mpg, Hwy miles about 480 to tank, hwy & city I got about 454. Its a good looking truck. I get compliments on it all the time. I havent done much to it, Stainless wheel to wheel nerf bars & tubular grill & soft snapless extreme tonneau cover, everything else stock.

  Falling in Love...with a pickup - 2007 GMC Sierra 1500
  By smokchasr - August 27 - 12:06 pm

  The fuel economy is as advertised. Switching to four-cylinders when cruising has yielded an average of 20- 22 mpg. In Montana, that is huge. We need 4x4 pickups that have this available power, comfort, and improved fuel economy for the obligatory long drives.

  P-O-W-E-R! - 1995 GMC Sierra 1500
  By HappyTexan - August 25 - 10:00 am

  Now ive seen my fair share of powerful trucks but this is the fastest out of them all.190 horses doesnt seem like much but belive me it is.Since we bought it in late 2003 we havent had a chance to put it to the long term reliability test.Weve owned (older) chevrolets,fords,and even dodges in the past but this thing stands out from the rest of them.This thing can tow like a bat out of hell and it still lets you know what its made of.We have the Z71 package and it has an ok ride...what youd expect from a pickup of its size and since it has a three inch lift kit it compromises the ride a bit.t gets about 13/16 as a usual truck

  my truck - 2003 GMC Sierra 1500
  By wright - August 25 - 10:00 am

  The automatic dual climate control is nice, but in the auto mode...you cant seem to keep the interior as cool as you might want. The silent recall concerning the rust behind the front bumper was something I was definately unhappy about. I had to learn about it on the internet, and when I took it to two different dealers, I got a bit of the runaround. Both claimed that I had the only truck that had been brought in for this problem.

  04 much better than 99 - 2004 GMC Sierra 1500
  By GaDawg - August 23 - 2:23 pm

  I purchased a 2004 Sierra after buying a new 1999 one which was a DOG. I went against my better judgement and ordered the 99 knowing that GM never gets a new model right in the first year but I also know that after building the same truck for 5 years GM gets the bugs out, I was right, the 04 is much better than the 99 otherwise I would have shot myself by now
