2007 GMC Sierra (Classic) 2500 HD Crew Cab Review

By

You can thank the Coca-Cola Company for attaching the term "classic" to a product that should actually be termed "old." The latest company to grab hold of this scheme is GMC. With the arrival of the all-new Sierra, the previous model forgoes mothballing to become the 2007 GMC Sierra Classic. A capable pickup truck by all measures, the Sierra Classic continues to offer a full range, including 1500, 2500 and 3500 models in Regular Cab, Extended Cab and Crew Cab configurations. Despite the Sierra Classic's age, it can still pull, haul and luxuriate with the best new rivals from Dodge, Ford and Toyota.

You'll Like This Car If...

If you need a serious work truck, one that can haul loads of dirt or tow a horse trailer, there is a Sierra Classic with your name on it. The Sierra Classic's interior can be made quite plush, especially with the Denali trim level.

You May Not Like This Car If...

If you are not used to piloting a large pickup, the Sierra Classic may be a bit too much truck for you. The Sierra Classic also lacks such newer conveniences as GPS navigation and side-curtain airbags.

What's Significant About This Car?

Entering its final model year, the Sierra Classic receives standard recovery hooks on 1500HD, 2500HD and 3500 trim levels.

Driving the Sierra (Classic) 2500 HD Crew Cab

Driving Impressions On the open road, you'll find the Sierra's steering is light, with modest feedback to the driver. On the other hand, the brakes get excellent marks for their rock-solid pedal...

feel. It should be noted that different wheel and tire packages will affect the way the Sierra feels on the road, so you may want to test-drive something that will reflect your final choice. Choose the available 5.3-liter V8, with 295 horsepower and a stump-pulling 335 pound-feet of torque, and you'll find that even a fully-loaded Sierra with a trailer attached can accelerate and pass without much hesitation. When not burdened with a heavy load, the Sierra's performance is practically muscle-car quick, especially when accelerating from a standing stop. The four-speed automatic transmission delivers crisp, precise shifts, and features a tow/haul mode that limits gear hunting when towing or driving in mountainous or hilly terrain.

Hybrid Drive
An electric motor mounted between the engine and transmission helps get the Sierra Hybrid trim rolling, saving gas as well as wear on the engine.

Denali Trim
The luxury-oriented Denali Crew Cab is a step above the SLT trim level.

The Sierra Classic's interior is nice, but starting to show its age. There is a lot of dark plastic on the dash face, and the plastics and other materials used on the dash and door have a generic look. Denali models get a bit more color and contrast with their trim and interior fabrics. The Sierra Classic's seats are soft but comfortable, especially when covered in leather. Those who regularly carry two or more people will want to get the Crew Cab for its roomy rear seat; the Extended Cab is best used for short trips or to provide a secured storage area.

Exterior

GMC has tried to distance its trucks from their Chevy counterparts with a bold grille design, different wheels and the upscale Denali trim option. The Sierra Classic maintains that tradition with a boxy middle section tempered by rounded edges and the familiar GMC logo proudly centered in the grille. Though older than the F150 and Dodge Ram designs, the Sierra Classic still strikes a powerful stance, especially when outfitted with the Denali trim package.

Notable Equipment
Standard Equipment

Base SL models have cruise control, CD player, air conditioning, tilt wheel and chrome-styled steel wheels. SLT and Denali models get a four-speed automatic, electronically controlled transmission with overdrive and tow/haul mode and a 4.8-liter V8 or 5.3-liter V8. Other models can be equipped with engine choices that include the 6.0-liter V8 and the 5.3-liter hybrid.

Optional Equipment

Options for the Sierra are too numerous to list. Beyond the various bed lengths, wheelbases and cab configurations, you can opt for the StabiliTrak stability management program, a number of off-road and towing packages and the OnStar telematics system. SLT and SLE Extended Cab two-wheel-drive models can be outfitted with a new Performance Edition package that matches a 6.0-liter high-output Vortec V8 with 20-inch chrome wheels, high-performance suspension, 3.73 rear axle, automatic locking differential and traction control.

All around terrific vehicle

"I have had this vehicle for 7 years and it has not needed anything major. I have been diligent on oil changes and other services. The only thing that has been an intermittent concern is that it is only 2WD. Washington doesn't get that cold, but when it does, the truck is not very good in inclement weather. It is sturdy, powerful, comfortable. Holds up great to wear and tear!"

"First the good, the seats are SO comfortable, the truck has a lot of room in it, it does what it should do these days, hauls people and stuff. That's about it. For the rest of it: Small thing, when in Drive, the shifter is in the way of the speed knob for the HVAC, oversight I suppose, but it's clumsy and not appreciated. Medium thing, the rear doors sound awful hollow and pop when closing, but they seal tightly. Unlike the passenger rear window, they leak, this truck is the pop out window, does not roll down. But the top of the passenger side leaks on many of these trucks. Then, there are the big issues.. The 5.3L leaks oil. It drips on the exhaust pipe. It drips out front of your house, driveway, work, school... it smells terrible, and you have to remove the transmission (4L60E that is a so-so tranny) and 4wd transfer case to get to the rear seal to even hope to fix it... and it's about an 90% success rate from what I hear and read if you DIY. It's a THOUSAND DOLLAR FIX for a shop or dealership! The Ford's $1200 spark plug issue is just as bad, but still, that is ridiculous, an oil leak???? We've been building engines for how many years now? We should not have leaks this day and age. Also the slip yoke slides around quite a bit, and therefore gives the "famous" (infamous) driveline clunk. Another "normal" issue. Supposedly no damage, but I don't believe it. They've made a $300 replacement nickel plated yoke, but who's realistically going to buy that? Overall, it gets from point A to B, it's a nice truck, it's a shame that it has issues that it just flat out should not have."

"I got this truck with 137,122 miles on it. When I got it home, it didn't pass WV inspection. I had to replace both front ball joints and the daytime lights for it to pass. I later had to replace the bumper because it was rusted out. I recently took it to the shop to replace the left front ball bearings. Eventually I will have to replace the front bumper. Other than that, it has been a wonderful truck. I would call my truck a fairly reliable truck with miner repairs. It's comfortable, maybe a little stiff with a good and OK smooth transmission. I wouldn't trade my truck for and new truck."

"I've had this truck since it had 14k miles, have always enjoyed the handling even though it spent most of its life fully laden or close to it. It has been replaced in the field and is now enjoying retirement. Now that I get to enjoy it without the burden of tools and supplies, I plan/hope to see it hit at least 300k as it still runs strong and sails through emissions testing every time."

"I really like the ride. The power is really good. I like knowing I can run E85 in it if I want to and switch back to regular gas if I want. I've owned mine for over 7 years and I love it. I will definitely by another GMC when I am ready for a new (or newer) pick up. I've only replaced tires and brakes in it besides fluids."
