2002 GMC Sierra 2500 HDVisitor, Boyce, LA, January 22, 2012 20:05I started to here a pulsation noise behind my glove box area about every 30 seconds. With my hand I reached under and located the noise against the fire wall. I found a damper that was opening and closing back and fourth. Then found out I have a cabin air filter; changed them out with new ones. Thought that would be the problem, but I still have this damper wanting to pulse back and fourth from open to close. I pushed the damper with my hand a few times but it still wants to go from open to close. Is this some sort of a vacuum problem or maybe an electrical signal telling this damper to go back and fourth? I think this is a damper to bring in outside air into the truck cabin.Flag ThisLike0

2006 GMC Sierra 2500 HDVisitor, Rockport, TX, October 04, 2011 08:42I bought june 2006 from now defunct dealer lawrence marshall. I drove it over every bumpy road i could find and didn't rattle at all. In september the doors started rattleing and the seats squeaking and noise from dash.The doors the worst,it make a noisy clacking and bumping every start and stop and on bumpy roads,they were able to fix only the seats . April of 2011 the dash stated making a steady bumping noise,internet research says it is A/C actuators.So at 45,000 milesit rattles like a 10 year old junker and i guess the A/C will fail whenever..Oh yeah,,the tail light assembly fell out of the left side in august 06 and the right one fell out sept 09,,only vehicle i have ever owned in 50 years that tail light fell out of voluntarily....ha!!Flag ThisLike0

2009 GMC Sierra 2500 HDrextrader09, Chino, CA, December 09, 2010 11:34Overall, the truck seems to be quite nice. I have had GMC trucks in the past and this new one lives up to its reputation for a solid performer. I do have one beef, that is the shocks...for some reason GM does not pay enough attention to their shocks. They should contract w/Bilstein on their non-Z71 suspensions. I wind up replacing the stock shocks w/Bilstein's, makes the ride a bit firm, but definitely worth it.

2001 GMC Sierra 2500 HDVisitor, Rockaway Beach, MO, November 22, 2010 21:05I bought this truck in August 2001 with 5,500 miles. Now has 152,000 miles. Engine is 8.1 liter with Allison 5speed. Don't think I'll ever part with it. Gets about 14-15mpg empty if driven sensibly, and about 10mpg pulling my 35' 5th Wheel that empty weight is 12,500#. And this truck is a 4x4. With exception of a couple minor sensor issues, It has performed flawlessly.Flag ThisLike | 1 person likes this1

2006 GMC Sierra 2500 HDVisitor, Colbert, WA, September 24, 2010 22:38I really like mine. 8.1 has plenty of power and does as good on fuel as the 6.0. I had leaking oil cooler line that I had to replace outside of warranty. Other than that, its been a good truck. Only have 42k miles on it ytd.Flag ThisLike0

2003 GMC Sierra 2500 HDVisitor, Sidney, OH, September 15, 2010 18:57This truck is starting to nickel and dime me. The block is leaking coolant. The windshield is leaking when it rains (the mats are wet after a rain). Tranny slipping occasionally. Ignition sometimes won't immediately disengage. Trim package is bubbling. This truck heading down the Lemon Path.....Flag ThisLike0

2003 GMC Sierra 2500 HDVisitor, Ortonville, MI, July 29, 2010 16:16comfortable and with the 6.0 liter gas V8 an acceptable tow vehicle for my 3 horse trailer. Lots of trouble early on with the steering sector that GM didnt find a solution for until AFTER it was off warranty. Poor gas mileage empty (12 to 12.5) but get about 11 when towing a full trailer. Replaced a radiator at only 70,000 miles and have had trouble with ABS sensors at about 60,000.Flag ThisLike0

2003 GMC Sierra 2500 HDVisitor, Dove Creek, CO, April 18, 2010 11:39I don't have a Duramax I only have the 6.0 Liter Vortec engine but it pulls just fine. I love this truck to death!!! I just need to find a solution on how to get better fuel economy and how to fix my cruise control that just went out about a week ago.Flag ThisLike | 2 people like this2

2005 GMC Sierra 2500 HDfremanus, Portales, NM, August 17, 2009 19:27I have had this truck since new in 2005. It definitely is the most comfortable truck I have driven in 33 years driving. Prenty of power, but you pay in MPG with 15 city and 19 road driving just speed limit...if you speed...then drop that 20% and if you tow heavy trailer or boat it drops 40%...shame. I have had trouble with suspension and steering components. The power steering hose both leaked and the power steering box needed replaced at 80,000 miles. The Left front wheel bearing went out at 75,000 miles. This is a sealed unit and wish they went back to greased bearings. These problems are well known with GM, but they have not corrected them. Good truck overall and will drive it till the wheels fall off. This is my second diesel Chevy.
