My wife stole it from

by on
Vehicle: 2008 GMC Sierra 2500HD

The GMC 2500HD is the most fun I've had driving out of any vehicle. It's powerful, looks good, and can haul a ton of cargo without a problem. Only complaints are the stiff ride quality from so many leaf springs, and it's a helluva gas guzzler. No issues with maintenance, and never ran across any major problems (even after 100k mi). The interior is somewhat simple but has nice accents, and is very roomy inside for big folks like me. My wife likes it so much she stole it from me. No hard feelings. Am I a happy camper? Yes. Would I buy it again? Most definitely.

Body moulding falling off

by on
Vehicle: 2008 GMC Sierra 2500HD

My 2008 GMC diesel pickup has 41.000 miles and has been a good truck. However it will be 5 years old in December, and the body moulding on each side is loose and starting to fall off. The dealer said it is a common problem, but since it is out of warranty they would not fix it. I went to a body shop, and the person there said it is a common problem with that body style. He said a solution is to remove the moulding and glue and buff out the paint. His estimate was $240.00. I'm disgusted that this problem should occur on a $40,000 vehicle. I see 25 year old cars and trucks with the body moulding still intact. I'm disappointed GMC won't take care of the problem.

Used to pull loads of 7 to 9 thousand pounds over 600 miles @ 70 MPH.In fact I liked the truck so much when we got our new 2011 GMCs I bought this one from the owner.now she is retired but I would'nt hesitate to drive the truck anywhere.

2008 gmc 2500 diesel

by on
Vehicle: 2008 GMC Sierra 2500HD

I bought this truck from a local used car dealer. I drive this truck mostly through the mountains of southwestern PA hauling my travel trailer. I previously owned a 2005 F250 diesel. There is absolutely no comparison between the two trucks. This GMC outperforms the ford in every way possible. I never thought I would say this considering my grandfather, my father, and I have been ford guys our entire lives but the proof is in the way the truck drives, handles, pulls, and the reliability I have experienced with this truck. I have driven this truck for more than 15,000 miles and overall I am completely satisfied. I have to say that this is by far the best truck I ever owned.

So far, love it.

I bought my 08 SLT, Diesel on New Year's eve day, 08. I have put on 17,000 miles mixed mostly highway and suburban with a good bit of weekend warrior hunting and camping trips. I commute in this baby and my combined mileage is 15.7 over the last 9 months. That's with a cap on the back,and with 35 miles a day in hardcore SF Bay Area highway traffic hell. I don't tow but it will haul a back end load of hunting equipment, dogs and coolers full of meat. Honestly, I could use a lesser truck for most of what I do, but when I need to step up this truck takes it and keeps going. I can stick 3 dogs in the back of the cab, w. seats folded and they ride in comfort and one of them clocks in at 120lbs

My first 3/4 ton truck

Vehicle: 2008 GMC Sierra 2500HD

I previously owned a 1999 Silverado 1500 4X4 Extended Cab Standard Bed and a 2007 Sierra 1500 4X4 Extended Cab Standard Bed I wanted to upgrade to something more powerful with more room. While I really don't need it for towing at this point, I can only imagine how great of a towing vehicle this will be. I am very impressed with the power of the Duramax diesel, as well as how quiet it is compared to the Ford Power Stroke and the Cummins in the Dodge. I test drove all 3 brands, and what won me over was the performance and power of the Duramax, as well as how much smoother the Allison Tranny shifted over the transmissions in the Dodge and Ford. The interior is the best of the 3.


Full 2009 GMC Sierra 2500HD Review

What's New for 2009

The 2009 GMC Sierra 2500HD receives the latest version of OnStar, which includes turn-by-turn navigation. There's also available Bluetooth phone connectivity, and the optional navigation system offers an available real-time traffic feature. Additionally, a back-up camera is now optional on extended and crew cabs, and stability control is standard on all 2500HD models with the standard-length cargo box.


If you want a heavy-duty pickup, the options are limited. The Big Three American manufacturers are the only players in this segment, and to the casual observer, their respective entrants may appear to be mere variations on a theme. There are significant differences among these workaday behemoths, though, as the 2009 GMC Sierra 2500HD demonstrates. Having received the most recent redesign in its class, it's an up-to-date truck, and its superior driving dynamics and extraordinary interior quality nicely complement its expected hauling and towing talents.

The 2009 Sierra 2500HD receives a handful of useful upgrades, including a new version of OnStar, available stability control and Bluetooth connectivity. The rest of the truck remains unchanged from its complete overhaul two years ago, which brought fresh styling, a dramatically improved interior, better handling, a more powerful engine lineup, a stronger frame and higher payload and towing capacities. As ever, this is a truck that will get the job done. Thanks to these changes, it will also keep you comfortable while doing it.

Whether you opt for the Sierra 2500HD or its Chevrolet Silverado 2500HD twin, you can't go wrong with these well-mannered brutes. The Ford F-250 is its closest competitor, but the GM trucks are a bit more capable, and they arguably offer a nicer interior, particularly in the SLT trim. The Dodge Ram 2500 nearly matches the Sierra's towing capacity and ride comfort, but it is getting along in years and will soon be replaced by an all-new model. It also can't match the GMC's cargo bed configurations or interior quality. That leaves the 2009 GMC Sierra 2500HD as your best bet. Along with its Silverado sibling, it rules the roost -- for now -- in this hard-working segment.

Body Styles, Trim Levels, and Options

The 2009 GMC Sierra 2500HD full-size heavy-duty pickup is available in three body styles: regular cab, extended cab and crew cab. Regular cabs come with a long bed, while extended cabs and crew cabs can have either a standard or long bed. Regular cabs are offered in base Work Truck (WT) or midlevel SLE trims; extended and crew cabs can also be had in plush SLT form.

The WT trim comes standard with air-conditioning (optional with the regular cab), a trip computer, a CD player, satellite radio, OnStar, vinyl seating, a 40/20/40-split front bench seat and a tilt steering wheel.

The SLE trim adds deep-tinted windows, chrome-style steel wheels, cruise control, full power accessories, heated exterior mirrors, dual-zone automatic climate control, cloth seating, keyless entry and a leather-wrapped steering wheel.

The top-of-the-line SLT is only available with the extended and crew cabs. It adds a locking rear differential, a heavy-duty trailering package (with an integrated trailer brake controller), remote engine start, an upgraded dash design, a Bose audio system with a six-CD changer and rear audio controls, 12-way power-adjustable heated front bucket seats and leather upholstery.

Options, depending on truck configuration, include a back-up camera, a power-sliding rear window, a navigation system with available real-time traffic, a rear-seat DVD entertainment system, rear park assist, a sunroof, camper-style side mirrors, the Z71 Off-Road package (including skid plates, off-road suspension and a locking rear differential), a safety package (including power-adjustable pedals and park assist), a cargo management system and an "EZ lift" tailgate.

Powertrains and Performance

A 6.0-liter V8 generating 353 horsepower and 373 pound-feet of torque is standard on all Sierra 2500HD trucks, as is a six-speed automatic transmission. Optional is a burly Duramax 6.6-liter turbodiesel V8, which boasts 365 hp and a space-time-continuum-wrenching 660 lb-ft of torque. The turbodiesel comes paired with an Allison six-speed automatic. Properly equipped, the 2500HD can haul up to 3,458 pounds and tow up to 13,000 pounds.

Buyers have a choice of either rear- or four-wheel drive. A WT with 4WD has a traditional floor-mounted selector for the transfer case. The two other 4WD trims have Autotrac, which features an automatic setting that shifts into 4WD when wheel slippage is detected.


Antilock disc brakes are standard, but front side and side curtain airbags are not available. Stability control is standard on extended- and crew-cab models with single rear wheels but is unavailable on all other models.

Interior Design and Special Features

The 2009 GMC Sierra 2500HD features two different interior designs depending on trim level. The WT and the SLE sport a traditionally trucky dash design with an open lower center portion to accommodate the standard three-person front bench (a center console is added with the optional bucket seats). Conversely, the top-of-the-line SLT gets the same layout as the GMC Yukon SLT SUV, which lends the Sierra's cabin a classier feel, thanks to its luxury-carlike center stack design, high-quality materials and wood and metallic accents. Either way, the controls are straightforward and relatively easy to reach, though the available dual-zone climate controls are small and difficult to operate with gloves.

The front seats are quite comfy, though some editors found the pedals placed too far apart for comfort. Moreover, the tilt-only steering wheel is located too close to the dash for longer-legged operators. Space in the crew cab's backseat is plentiful, while most average-size adults should find the extended-cab's backseat acceptable. A welcome addition for 2009 is the optional rearview camera for extended- and crew-cab models, which makes parking easier and also streamlines the process of hitching up a trailer.

Driving Impressions

Compared with the heavy-duty trucks from Ford and Dodge, the 2009 GMC Sierra 2500HD distinguishes itself with well-weighted steering that gives the driver a greater sense of vehicle control. Heavy-duty pickups are never going to ride like luxury sedans, but the 2500 is surprisingly quiet and comfortable over long distances. Both engines are strong, but if you can swing the price premium, the brawny performance and decent fuel economy of the Duramax diesel make it a tempting choice.
