Common problems with the 1997 Cougar
NHTSA's file holds 76 owner complaints on the 1997 Mercury Cougar. Owners named engine cooling most often: 30 complaints, and half of the 20 that list a mileage came after 69,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine And Engine Cooling | 30 | 20 | 70,000 |
| Power Train | 10 | 1 | Under 5 mileages |
| Service Brakes, Hydraulic | 9 | 1 | Under 5 mileages |
| Fuel System, Gasoline | 8 | 2 | Under 5 mileages |
| Suspension | 6 | 1 | Under 5 mileages |
Of the 76 complaints, 2 report a crash, 2 report a fire and 2 report an injury (2 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 1997 Cougar
The 26 mileages owners gave run from 33,212 to 156,000 miles. A quarter are at or under 51,000 miles, half at or under 70,000, three quarters at or under 88,075 and nine in ten at or under 138,434; 5 (19%) came after 100,000 miles, 1 (4%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 1997 Cougar 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: 21 of the 26 came at or under 100,000 miles, so they say nothing about how many miles a 1997 Cougar can cover.

Is the 1997 Cougar a good year?
Complaint counts cannot say whether the 1997 is a good or a bad Cougar: they rise with how many were sold and how long they have been on the road. They show how the 1997 compares with the other model years in NHTSA's file.
With 76 complaints, the 1997 ranks 11th of the 18 Mercury Cougar model years from 1984 to 2002 with 10 or more complaints, counting from the most. The most: the 1999 (454). The fewest: the 1985 (10).
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 |
|---|---|---|---|
| 1984 Cougar | 17 | 1 | Under 10 mileages |
| 1985 Cougar | 10 | 0 | Under 10 mileages |
| 1986 Cougar | 13 | 1 | Under 10 mileages |
| 1987 Cougar | 33 | 0 | Under 10 mileages |
| 1988 Cougar | 55 | 2 | Under 10 mileages |
| 1989 Cougar | 81 | 6 | Under 10 mileages |
| 1990 Cougar | 86 | 4 | Under 10 mileages |

1997 Mercury Cougar recalls
NHTSA's recall files of November 11, 2026 list no campaign for the 1997 model year under the name COUGAR. Recalls can be filed under another name (a trim, a body or a series name), so a recall may still exist for the 1997 Mercury Cougar: check the VIN with NHTSA's free recall lookup.
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 1997 Cougar 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 1997 Cougar.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 50 of the 76 complaints on the 1997 Mercury Cougar 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: COUGAR. 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: COUGAR.
