It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

GMC Owners' Reviews
Nice vehicle for hauling a family and full load, lots of room. We bought our 2003 Yukon Denali brand new. Issues we have had with this car have been the following : 1. Replace the intake gaskets, very pricey fix about $1000 2. Instrument panel lights 3. Rear suspension auto levelling system went bad, installed aftermarket overload suspension to replace the auto level system 4. Leaks from power steering pump 5. Tire wear not even due to articulating wheels 6. Front steering issues due to worn ball joints and other worn items
We did not get any of the recall items sent to us from the manufacturer, there appears to be three recalls dating back to 2003 and 2004.
This vehicle cruises real nice down the highway, gas mileage not stunning we usually get 15 mpg in town and 17 mpg on highway, I have personally done all the oil changes except for one but we always used a synthetic blend oil. I don't think the Yukon Denali XL is worth the extra money spent to get it, compared to the regular Yukon XL, we had two YUKON XL and now this YUKON DENALI XL, the price difference quite a spread. I was satisfied with our vehicle but I would have been better off with the YUKON XL two wheel drive model.
I brought my 2001 Yukon XL Denali new and still drive it today. It has 183K+ and is still in what I would call excellent condition. I'm a mechanic and have done all of my own work after my warranty expired. Although, I've had many parts failures (2 x more than my 97 Chevy C1500 PU which I also still drives), I still would rate this vehicle as "good". The largest part replaced was front differential @ 70k good thing I purchased the extended warranty package. Then there is your normal parts that wear out as well as your service parts (tires, wiper blades, brake pads, rotors and park brake shoes, air & fuel filters, fuel pump, ect.) but I did have problems with water leaking in on passenger floor, an annoying squealing noise and engine serpentine belt wearing faster than normal which took a couple of years of going back and forth to dealer (vehicle under warranty) and they found nothing. So I decided after the warranty ended to T.S. myself and after changing about 3-4 tensioners I decided to buy a high quality tensioner that corrected the belt alinement & wear problem and replacing the A/C belt & tensioner took care of the squealing noise. I just found that the moon roof clogged drains where the culprit that allowed the water drain onto the pass. floor. I would recommend this vehicle.
Bought my 05' Denali new and it now has 99,100 miles on it. It's been a great SUV but it might be showing issues now. 1) I hate the fact the front seats don't recline all the way. 2) Electrical issues (radio turns off for no reason, bulbs burn out all the time, dash lights lite up like a Christmas tree and shut off for no reason, POSS Traction button engages for no reason. 3) AC/Heater doors lock in wrong position. Replaced them already at 67k. AC get hot when I want it cold and the Heater gets cold when I want heat. WTF?? 4) The water pump went out. 5) The rear defroster cable broke off. 6) The brake cable broke. For an American car, it's pretty good. Comfortable to drive and has great power but the gas mileage sucks! 10-11 miles to a gallon?? Time to trade it in.
Paint comes off the body in big flakes very bad paint work. I have seen many of the same issues
I used to work at Chevrolet Dealership before I bought a truck i did My home work. I bought a 2006 Sierra because in 2007 the Cast Iron blocks went away and more aluminum started being introduced as well as plastic. However, I did have a major problem with the Clutch some truck that were assembled in Mexico utilzed a master cylinder with a shaft approximately 3/16" too short making it very difficult to Clutch. That one was hard to resolve especiallly because GM and the Dealers wouldn't help. Less is more when it comes to vehicles in my book Less electronics less fancy stuff more time for me and my wallet.
