Review of the 2002 GMC Sierra 2500HD

  • GMC makes a pretty good pick-'em-up, if powerful engines are your thing. But it has a ways to go to match the Ford F-250 Super Duty when it comes to the quality of the materials and rugged good looks.

  • Safety
  • Pros

    Class-leading horsepower and hauling capacity, roomy interior.

  • Cons

    Unproven engines and drivetrains, cheap interior materials.

  • What's New for 2002

    Fully redesigned last year, the Sierra 2500HD gets only minor updates for 2002. Air conditioning is now standard on all trim levels along…

I'll only buy duramax

Vehicle: 2001 GMC Sierra 2500HD

This is by far the greatest and most comfortable truck ever made. And if power and performance are what you want then this is the truck for you. The only trouble I had was with the injectors and luckily they were covered by the LB7's extended 7year/200,000mile warranty. Other than that I have never had trouble with this truck. Plus the aftermarket for Duramax's is so wide open to your imagination.

Vehicle: 2001 GMC Sierra 2500HD

I bought the Duramax, had a 2001 f250 figured I'd try it. Man let me tell you, quite as a mouse compared to Dodge and Ford and the power surprised me. the leather is no comparison to Fords, (does Dodge have leather?) When we moved from W. Colorado to Central TX I pulled a trailer ( over 8,000 lbs) over those mountians not even much strain, fact had to wait for the Ryder at the top, but no surprise there. My wife wants one now, the ride is like a good sedan and Im not kidding its that good, my fuel varies between 20 - 21 mpg our Ford around 16mpg 4 people who have driven my truck bought one, best vehicle I've ever had.

Not professional grade

Vehicle: 2001 GMC Sierra 2500HD

The 6.0 engine knocks a little until warm...other than that it's ok. Lacks real pulling power, even with a 410 rear end. Tranny went out at 9700 miles. Power window regulator at 37000 miles ($500), Rotors now acting up at 47000 (all of a sudden??) Pampered truck. Goes to FL with a light trailer and back annually, othewise no strain. Hauls nothing. Looks like the 8.1 and the Allison was the way to go. Ride was real choppy from day one. I mean bouncey on an uneven road! Hang on in the rear seat! GM should be able to do MUCH better than this. They say every HD truck is made for 200K...at what expense?
