How many miles is too much for a used Cougar?
There is no hard cutoff. NHTSA's file records when owners reported problems, not when a Cougar wears out, and how a car was maintained matters more than any one odometer figure.
Where the complaints cluster: the middle half came between 45,000 and 100,000 miles, and 6% came after 150,000 miles (29 of 471).
Complaint mileage rises with a model year's age: older Cougar years were reported at higher odometer readings because they had more time to cover miles. The table below shows when owners of each year reported problems; it does not rank the years.
Mercury Cougar mileage at failure by model year
Each row is a Cougar model year with 10 or more NHTSA complaints that list a mileage, with the median of those mileages: half of the year’s complaints came at or above it. Years with fewer are left out. Medians rise with a year’s age, so the table does not rank the years. A linked year opens that model year’s own page: its problems by component and its recall campaigns.
| Model year | Complaints listing mileage | Median mileage at failure |
|---|---|---|
| 1993 Cougar | 18 | 114,522 |
| 1994 Cougar | 15 | 75,000 |
| 1996 Cougar | 19 | 80,000 |
| 1997 Cougar | 26 | 70,000 |
| 1999 Cougar | 128 | 68,000 |
| 2000 Cougar | 99 | 65,000 |
| 2001 Cougar | 51 | 69,900 |
| 2002 Cougar | 79 | 66,600 |

What these mileages can and cannot tell you
- They are self-reported. The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- They are not a lifespan study. The file holds only cars whose owners reported a problem; a Cougar that ran without one never appears in it, so these figures do not say how long a typical Cougar lasts.
- Young model years pull the figures down: a car a few years old cannot have reached high mileage when its owner complained.
- A complaint is an allegation, not a defect finding, and the count rises with how many cars were sold.
- 1,410 of the Mercury Cougar complaints in these model years give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every figure.
- NHTSA also holds 5 complaints for 1982, 1983 and 1998, fewer than 10 a year under a name whose typical year draws 40 or more; those stray filings are left out.
- NHTSA names counted: COUGAR.

How do I check the mileage of a used Cougar?
Compare the odometer with the readings on file for its VIN: title transfers, inspections and auction sales record the mileage on the day.
