Owner Reports

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's handling is more agile, and the steering and brakes feel better than in the previous generation. The ride is supple and controlled. Interior quality and the seats are much improved. It retains impressive trailer-towing capability. The 5.3-liter engine is powerful, but the Tahoe twin we tested delivered only 14 mpg overall. The Yukon typically seats seven or eight but offers little cargo space behind its cramped and very low third-row seat. 4WD models have a selectable full-time system that can remain engaged at all times without worry. ESC is standard. A hybrid version is available and Denali models get the 6.2-liter V8 and six-speed automatic for 2009.
