Have had continued problems with the drive train, from transmission noise to multiple problems with the front and rear differentials noise and leaking. Vehicle seems reliable in most cases, but leaves that nagging feeling that once the warranty is off I'm going to be looking at repairs on a low milage vehicle (only averages 500 per month). Much fun to drive, but the overall fuel mileage is a w f u l, but that goes with the territory of the 6L engine and the rear end selection.
For every day driving in southern California, also to haul horses, fuel economy has been good, the diesel engine surprisingly quiet. The Allison tranny holds speed going down hill. After hauling horses with the Allison tranny, through incredibly smooth decelerations, I don't think I'll go back to brand X. All in all a Great truck, Very sporty ride compared to its predecessor.
I purchased my 2002 Chevrolet 2500HD 4x4 Ext cab truck in 2003. Other than the fuel economy of this truck, I have no compliants. I take care of it but I also use it as a truck. I am a hunter and commonly go off-road on some horrible roads. I have never been stuck and the truck is all stock. I plan on keeping this truck for a long long time and hopefully passing it on to one of my sons as a first truck. Chevrolet really put time, heart, and guts into building this machine!
I bought this truck new, 2 miles on it when I test-drove it. BEFORE I bought it, a fluid line exploded all over the engine. That should have been my FIRST indication to drive off and leave it! My husband & dad said it had a "warranty" to go ahead and get it. WRONG! That was ONLY the beginning! The local dealership could not get the problems that I had fixed on this truck like: replaced drive shaft for truck tugging when driven, replaced power- steering pump, noise when backing up, jerks when pulling a horse trailer, severe gaps when applying brakes, headlight dim extremely low for no reason, and the list still goes on!
