I've had my 2002 Sierra Denali for 3 years and the truck has served me well. The 6.0 V8 will run forever as long as you maintain is regularly. I did buy an extended warranty on my truck that came in handy. The rear dif was making noise, but the warranty covered a full tear down of the dif and quadrasteer and rebuild with new factory parts, done at a quality GM dealership. The front wheel bearings on these trucks tend to need replacing as well around 150 as the sensors in them go bad causing abs malfunction. All these problems aside, the truck is something you will rarely find the same build quality anymore. The quadrasteer works amazing towing trailers and parallel parking tight spots. 13.5 mpg is rough, but we'll worth the luxury this vehicle brings. I will run mine until she dies!
Mine has been a great truck! Love the quad steer, The brakes are quite weak.
rear steer is crap ,, when it goes bad ,it goes real bad vary expencibe to fix and no one kniows how to fix them
2002 Sierra Denali. Overall great truck. Engine is has plenty of power. Love the AWD and Quadrasteer. 82K miles on it now. Avg MPG is 12.7 :( Only problems I've had is the brakes are complete crap, replaced orignal pads at 70k and its difficult to find the right parts at any parts store. Front rotors are from the yukon and rear is from a sierra. Rear brakes are a nightmare. Not exactly sure of the problem, but the pads are shot on the inside of the rear (outsides are fine). Front rotors (aftermarket) are shot as well warped. Going to replace all calipers, flush brakes, replace all rotors with performance rotors and install performance pads and see how the brakes are. Replaced original tires at 65K; installed Bridgestone Dueler APTs handles great in the snow and rain. Installed K&N Filter Charger (big HP gain as stock air intake is restrictive) and new exhaust system (Cat back). Replaced power steering pump and Battery (2 times lived in AZ for 2 years). Rear Tonnaeu cover shot at 75K miles and the Side steps are rusting (IL winters). Had some minor issues with the interior dealer replaced drivers seat (cover) and the center console as the skin of the plastic seemed to have melted off in the Phoenix heat.

The A/C is great frigid cold A/C and the heater is inferno hot, also love the seat warmers.

Truck tow great, like the firm button for sagging with a heavier load.

Wish the truck was a crew cab and had a 6 speed tranny.
