Review

I've never owned a better truck. All the power you ever want without sacrificing fuel mileage. Hook it to anything and go anywhere. Great ride like a Caddy. No noise. Luxurious

Favorite Features

The 8.1 L Engine leaves others behind. Allison tranny is smoothe and exact.

My overall experience has been great! The only problem that I have had in the last 2 1/2 years is the driver side mirror defroster died and had to be fixed. No major mechanical problems and I think it is a comfortable full size truck to drive.

Favorite Features

Heated leather seats!

More toys, yeah I know it's a work truck but I love toys!

Review

This last year has been quite another story. I've had a complete Brake job including replacing all four rotors which were fine 2500 miles before. The sudden complete failure of all four brakes cost 1600 dollars for that. The four wheel drive switch has gone twice causing the truck to shift in and out of gears and fall out of 4WD. This also caused premature wear of the U-joints, which needed replacing. The fan motor now is going and needs to be replaced. The engine burns a quart of oil every 2200 miles and knocks like mad for the first five minutes of run time until it's warm. The engine also knocks if I use any gas other than premium.

Everything but the body needs work if you expect this truck to last more than two years.

Review

For a top of the line truck that listed for over $32000 new you would think the company would put in better seats ;such as more padding in the bottom seat and go back to having the whole seat move by power not just the bottom. (this is for the cloth seat). the seats in my 1997 were more conforbly , other than the seatr it is an excellent truck.

go back to power seat that move the the whole seat and more supput in the bottom of the seat

Duramax Diesel 2500HD Ext Cab 4X4

Review

Absolutely love this truck. Will buy one again in a couple years. The only thing I wish GM would improve is the turning radius for the long bed and stiffen up the fleet side metal... leaning against the outside truck bed wall, I pushed the metal in... it popped back out but left a slightly noticable dent. Also interior could make use of wasted space in the dash board below radio with bench seats.

Favorite Features

Duramax Diesel... expected 21 to 22 mpg, but only getting 19 to 20 mpg so far... gas mileage continues to improve as engine continues to get broken in... only 32,000 miles on it so far.

Suggested Improvements

Better turn radius for long bed

Review

I love my truck. It was bought to work and it does that. There is a lot of Maintnaice on this truck though. The style and beauty of this thing is awsome. I like the looks of this truck more than the new ones, but you know how guys are. We want the latest, greatest thing. Im sick of having to replace the main engine drive belt every 15000 miles. It starts squiling and I cant handle that. And it sucks the dealer never has the parts to fix a damn thing when you take there. You have to go back and forth two, three, or sometimes four times before anything gets fixed. great big bummer since there is not a dealer anywhere close to where i live.

Favorite Features

An automatic transmission that will hold up to the pulling.

Suggested Improvements

better service after the sale. longer service hours.

Review

I have owned many new vehicles from trucks to sports cars from Prosches (2), Corvettes (2), VW's (3), Fords (6), Dodges (1), Chevys (2), Mercedes, to Buicks (2). I have never owned any vehicle that has given me the driving satisfaction of never having a squeak, squeal, rattle, or mechainical problem: From dealer lot to 24,000 miles this has been an excellent vehicle and I congratulate GM for delivering the value. I gave this vehicle a relatively poor rating for gas economy but I do like the 6000 Vortec engine and I knew the gas requirements before I purchased the truck: I'd buy this engine again gas economy notwithstanding.

Review

I live in Michigan and tow a 35' 5th wheel camper to North and South Carolina 4 times a year. The trailer weighs 13,500lbs and this truck will take on any mountion on I-77 in the Virginia's. I get 7.5 mpg average towing which is much better than my 98 truck that had the old 454.

Favorite Features

1. 8.1 Engine 2. Allison Transmission 3. Heated very comfortable seats 4. Back seats fold down flat to give my 80lb Yellow Lab plenty of streach out room.

Suggested Improvements

1. Needs a bigger gas tank 2. Drop the Onstar from the SLT package (Drop Onstar totally) 3. Needs more bright colors to chose from instead of the boring traditional GM colors. Bright electric Blue or Green would be nice.

Review

I have had both Ford and Chevy trucks in the past and this is far superior. The ride is a bit more rough than my Chevy 1500, but it is more heavy duty and simply does more. The power is great and the Allison transmission makes it a dream to drive in the Rocky Mountains where we live.

Favorite Features

Comfort & towing power Allison Transmission

Ability to disable passenger airbag

Review

This is one awesome truck. We are appreciative of the creature comforts, all around visibilty, safety/security features and OnStar. I pull a 30 foot 5th wheel, (about 11000 pounds) and have been very impressed with the trucks ability and ease of maneuverability. I regret I didn't wait for a DuraMax, but I'm getting along fine without it.

Favorite Features

The power, ease of driving and comfortable ride (for a 3/4 ton HD.

Suggested Improvements

An adapter to allow the use of a cell phone with the OnStar Antenna.
