Mercury Mountaineer complaints, mileage and recalls by model year
Each row is a Mercury Mountaineer model year with 10 or more owner complaints in NHTSA’s complaints file of November 11, 2026. Its page gives the mileage when owners reported problems, the most-reported components and the recall campaigns NHTSA’s recall files list. A median is given with 10 or more mileages; medians rise with a year’s age, so the table does not rank the years.

How to read these numbers
- A higher count is not proof of a worse vehicle. Complaint volume rises with sales volume and with years on the road, and recent model years have had less time to collect complaints.
- NHTSA publishes owner reports without verifying them. A complaint is an allegation, not a defect finding.
- A complaint mileage is the odometer when an owner reported a problem, not how long the vehicle lasted.
- The make, model and model year are the ones on each complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- The recall count is the number of campaigns NHTSA’s recall files list under these names for the model year. Recalls can be filed under another name, and a campaign covers a production range: check the VIN with NHTSA’s free recall lookup.
- NHTSA also holds 9 complaints for 2 other model years with fewer than 10 each; those years have no page.
- NHTSA name counted: MOUNTAINEER. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.

Mercury Mountaineer questions
Which Mercury Mountaineer model year has the most complaints?
NHTSA holds 10 or more owner complaints for 13 Mercury Mountaineer model years between 1997 and 2010, 1,983 complaints in all; the 2002 (372) drew the most. The counts are from NHTSA's complaints file of November 11, 2026; complaints are owner reports, not proven defects, and the counts also reflect each year's age and sales.
Do complaint counts mean the Mountaineer is a bad vehicle?
No. NHTSA complaints are unverified owner reports, and the count rises with how many vehicles were sold and how long they have been on the road. They are useful for comparing model years of one model, which is what this page does, not for ranking one model against another.
How do I check a specific Mercury Mountaineer before buying?
Take the 17-character VIN from the vehicle and run it through NHTSA's free recall lookup, which reports open recalls within its coverage. For the vehicle's own past, VIN Lookup sells the original ClearVIN PDF for $14.99: title brands, odometer readings, accident and auction records on file for that VIN.
