GMC Sierra Denali Problems
Daytime Running Lights are Prone to Burning Out
The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2000-2003 models is #4114K (trade number).
Parking Brake Does Not Hold Due to Worn Parking Brake Shoes
Units with 4 wheel disk brakes may develop at situation where the park brake does not hold as it should. Our technicians tell us this can be caused by worn park brake shoes located inside the drum section of the rear brake disks. The worn shoes should be replaced and properly adjusted to correct this issue.
Check Engine Light Due to Gas Cap Issue
A Loose or worn gas cap may cause Check Engine Light to illuminate.
Check Engine Light Due to Restricted Secondary Air Injection Check Valve
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
ABS Light Due to Poor Electrical Ground Under the Battery Tray
A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.

RepairPal Expert Overview:
Some vehicles have a power steering hose that was not made to specification, and may rupture under extreme steering conditions. If this were to happen, power steering assist would be lost and steering effort would increase. On vehicles equipped with hydro-boost brakes, braking effort would also increase. If power steering fluid were to spray on hot engine parts, an engine compartment fire could also occur. Dealers will inspect the power steering hose(s) for the two suspect date codes and replace them if needed. The recall began October 14, 2005. The GM recall number is 05086.

GMC Sierra Denali Stories
The Auto Mode Air Conditioning system on the driver side is giving me some annoying problem. When I set the temperature, say 68 F and it start to blow cool A/C air and after some 10-15 minutes it change to very hot air. It will not change to cool breezy air even if you turn and change the temperature knob setting. I tried to turn it off first then turn it back on but still will not go back to cooler air temperature. I tried other A/C modes but it will not respond. The only way to reset this, I found out , was to turned off the ignition key, shutting down the engine then start the engine again. It is dangerous to do this while driving in the freeway. So either I have to exit and pull over to turn off and start the engine again to get some cool air or continue driving in the Hawaiian summer heat in the hot interior truck cabin. Is this a common problem? Does anybody out there experience this? The passenger side A/C is fine. I am thinking of putting a separate switch for the A/C so I can reset it without stopping the engine.
The rear bumper on my 2005 GMC Sierra Denali is rusting all to hell.
6.2 liter sounds like a deisel-very noisy. 6 speed trans vibrates in 6th gear. Dealer said they all do that! Still trying to get fixed under warranty. DON'T buy a 2010 Sierra Denali!
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.
Our Sierra Denali 2005 extended cabin is as comfortable as a luxury sedan, very roomy in the back, the kids love to watch their favorites DVD movies on the rear seats entertainment system. With its 6.0L V8 engine and 345 Horse Power we are able to tow up to 8,000 pounds. One very nice feature is that the all wheel drive system does not require the driver activation of the front wheels traction. We get 14-16 miles per gallon.
