The Yukon and Yukon XL full-sized SUVs offer impressive trailer-towing capability and a smooth, quiet ride--at least at low speeds. The V8s feel strong, and the automatic transmission shifts smoothly. The Yukon can also accommodate up to nine, but unlike the longer Yukon XL (a twin of the Chevrolet Suburban), it offers very little cargo space behind its cramped third-row seat. Handling is imprecise but ultimately secure.

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Model Summary
The Yukon and Yukon XL full-sized SUVs offer impressive trailer-towing capability and a smooth, quiet ride--at least at low speeds. The V8s feel strong, and the automatic transmission shifts smoothly. The Yukon can also accommodate up to nine, but unlike the longer Yukon XL (a twin of the Chevrolet Suburban), it offers very little cargo space behind its cramped third-row seat. Handling is imprecise but ultimately secure. Braking performance is so-so. 4WD models have a selectable system with a full-time mode. Stability control is now available. The up-level Denali is substantially similar to the Cadillac Escalade. A tip-up in the gov't rollover test is cause for concern.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2004 GMC Yukon owners. The owner comments describe problems respondents experienced with this vehicle.

Climate System

Blower (fan) motor, A/C compressor, condenser, evaporator, heater system, automatic climate control, refrigerant leakage, electrical failure.

What Owners Say

Automatic climate control

"The temperature select knobs are supposed to allow me to select a digital temperature at which to keep the car. Neither the left or right side control knobs were working properly when I bought the car. Both knobs could be turned but the digital read out just bounced around. For example: if the temperature in the car was set at 60 degrees and I wanted to turn it to 70 degrees, I could turn the knob in the direction that was supposed to increase the temperature setting, but instead of the temperature read out increasing as I turned the knob, it just bounced around between 60 and 65 degrees randomly. Both sides did this."

William M., TX (2004 GMC Yukon SLT 5.3-L V8)

"the car randomly spews out heat instead of a/c. Now that spring is here, the car can be cooling and then suddenly start blasting out heat full bore, requiring us to shut the vents off."

Steering wheel vibration

"On a smooth road the front end frequently has excessive vibration between 45 and 55 MPH as though it was the result of a rough road or driving over rumble strips, Rotating and balancing all four tires had no effect on the vibration. One service Tech suggested that bit was caused by the computer controlled timing to adjust the fuel (gas) based on the load. Another Tech said that would not cause this.

Engine Major

Engine rebuild or replacement, cylinder head, head gasket, turbo or supercharger, timing chain or timing belt.

What Owners Say

Engine rebuild or replacement

"After coming off of the interstate and slowing down, the engine was missing very bad. The missing stopped once I accelerated up to 50 mph. I took the Yukon to the shop I deal with and they spent 2 days and came up with the problem causing the miss. The valves on the second cylinder on both banks were not operating correctly at slow speeds. The lobs on the cam, for both cylinders in question, were worn down. The lobs on the other 6 cylinders were in good shape. I use this vehicle to pull a 6,000 pound camping trailer. The vehicle is rated to pull 8,200 pounds, so I was operating it within manufacturers specs. It seems that the cam was not hardened correctly. The engine had 190,000 miles on it when this occurred. I had a Jasper rebuilt engine installed and it operated better than the original ever did. Seems the original engine was already experiencing problems when I purchased it. The original owner provided all the maintenance records and none of them reflected any hint of a problem. Seems the engine was bad when it was installed and the servicing dealer never noticed or mentioned any problem."
