How many miles will a 1998 Mountaineer last?
The 51 mileages owners gave run from 1 to 210,000 miles. A quarter are at or under 62,000 miles, half at or under 85,000, three quarters at or under 117,000 and nine in ten at or under 145,000; 18 (35%) came after 100,000 miles, 4 (8%) after 150,000 and 1 (2%) after 200,000.
These mileages say when owners reported a problem, not when a 1998 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.

Is the 1998 Mountaineer a good year?
Complaint counts cannot say whether the 1998 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 1998 compares with the other model years in NHTSA's file.
With 236 complaints, the 1998 ranks 3rd 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.

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 1998 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 1998 Mountaineer.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 185 of the 236 complaints on the 1998 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.
