How many miles will a 2003 Mountaineer last?
The 117 mileages owners gave run from 30 to 240,000 miles. A quarter are at or under 47,000 miles, half at or under 78,784, three quarters at or under 98,000 and nine in ten at or under 140,000; 28 (24%) came after 100,000 miles, 7 (6%) after 150,000 and 1 (1%) after 200,000.
These mileages say when owners reported a problem, not when a 2003 Mountaineer wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: 89 of the 117 came at or under 100,000 miles. The 28 past that mark show the 2003 Mountaineer still being driven at those mileages, not how many reach them: NHTSA's file counts complaints, not the vehicles on the road.

Is the 2003 Mountaineer a good year?
Complaint counts cannot say whether the 2003 is a good or a bad Mountaineer: they rise with how many were sold and how long they have been on the road. They show how the 2003 compares with the other model years in NHTSA's file.
With 152 complaints, the 2003 ranks 5th of the 13 Mercury Mountaineer model years from 1997 to 2010 with 10 or more complaints, counting from the most. The most: the 2002 (372). The fewest: the 2010 (13).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 1997 Mountaineer | 328 | 31 | 124,000 |
| 1998 Mountaineer | 236 | 51 | 85,000 |
| 1999 Mountaineer | 151 | 39 | 70,000 |
| 2000 Mountaineer | 123 | 60 | 70,000 |
| 2001 Mountaineer | 22 | 13 | 75,000 |

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2003 Mountaineer lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2003 Mountaineer.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 35 of the 152 complaints on the 2003 Mercury Mountaineer give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- 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.
- Recall-file name matched: MOUNTAINEER.
