I have owned this truck sense October 2008. Service has been performed as recommended. I have not had any major problems with this truck what so ever. Minor problems I have had are the belt noise due to the power steering pulley misalignment and the rear tire wear due to factory door sticker calling for 70psi for the rear tires. Dealer took care of all and installed two new tires on my truck. Dropped rear tire pressure to 60psi. No more wear, Love the 6.6 Duramax with the Allison. What a combination. Tons of torque, great performance for a diesel, and quite. Average fuel mileage 18.5 back and forth to work and 22.4 on my last road trip.(12/09).
I was skeptical in getting another GM product as the prior 3 were trash.
I had an 05 2500 Diesel that would do nothing but overheat while pulling my toyhauler and the dealer said there were no issues.
I pulled this same trailer from Cali to Ga. loaded down with 13k + lbs and the only thing that was bad about it was my tires wore down after 20k miles.
This truck pulls like a dream and has no mechanical issues at all!!!
18 - 19 mpg on hwy and 11 mpg while towing with 1 size up on stock tires, could be a little better.
If I had to have a complaint it would be that you can't put an 18" wheel with a 285 tire under the front end without shaving the wheel wells.
Finally purchased the best BigBoy toy available. The Duramax 2500 LTZ is the best of both work and play. Makes light work of pulling my horses. The leather loaded Escalade like interior makes an A+ ride.
Imperial Chevrolet is horrible!! At least their service department is!! I have a 2008 Chevrolet Duramax 2500HD LTZ...a $55,000 truck when new. It is rusting all over the top of the cab. This truck get's detailed several times a year meaning it is taken care of! It has a 6 year, 100,000 rust / corosion warranty. But the service manager, Bill, decided they wouldn't cover it - no reason, just wouldn't. I called Chevrolet and was told its the dealers choice to cover warranty stuff or not - the company rely's on them! Really! As a compormise they would give me a discount to have the rust cut out and/or sanded out!! What!! It is under warranty!! This dealer is awful - their service department is t
