2003 GMC Yukon XL Denali Problems

Heating & Air Conditioning -- Verified

One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.

Electrical & Lights -- Verified

The rear window defogger may stop working due to a wire terminal broken off of the rear glass. Our technicians tell us that terminal can be reattached using a special glue or silver solder.

Electrical & Lights -- Verified

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 2001-2003 models is #4114K (trade number).

Suspension & Steering -- Verified

The steering wheel position sensor may fail, resulting in the service stability message being displayed.

Engine -- Verified

A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

2003 GMC Yukon XL Denali 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 will NEVER buy another GMC as long as I live.
I had trouble with it loosing power in the MIDDLE of the interstate. Like to have never got that fixed. The suspension light has been on since I bought it I've had that checked by different mechanics (couldn't find anything wrong) The check engine light has been on (had it put on machine to run diagnostics by different mechanics dealer and nondealer can't find anything and today the transmission went out. Yes it's 9 years old but my husbands Ford is 16 years old no problems. DO NOT WASTE YOUR HARD EARNED MONEY on these vehicles!! I keep my vehicles maintenanced according to the manufacturer.I don't pull anything behind it, I live in north Mississippi no high mountains to cause strain on the transmission.

I have had this car for 2 years with NO problems! I would buy a newer denali in the future!
