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 Mountaineer is a clone of the Ford Explorer. The standard V6 performs adequately but sounds coarse. The V8 is stronger and sounds better, but delivers just 14 mpg overall. The ride is stiff compared with its car-based competition. Handling lacks agility but is sound and secure. The versatile interior has various folding seat arrangements and offers three-row seating. Unlike the Explorer, the Mountaineer uses a permanent all-wheel-drive system without a low range. Towing capacity is generous. Overall, the Mountaineer is outdated. The Mountaineer is being phased out with the demise of the Mercury brand.
