NHTSA lists 2 recall campaigns for the 1991 Mercury Capri. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
THE RUBBER TUBE THAT CONNECTS THE TRANSMISSION TO THE TRANSMISSION OIL COOLER (IN THE RADIATOR) MAY DISCONNECT CAUSING DISCHARGE OF FLUID.
Risk: DISCHARGED TRANSMISSION FLUID MAY STRIKE THE EXHAUSTMANIFOLD OR THE EXHAUST PIPE AND RESULT IN A FIRE.
Fix: INSTALL REVISED LINE AND CLAMPS TO IMPROVE LINE RETENTION TO THE TRANSMISSION.
THE AIR BAG MODULES DO NOT MEET THE FORD SPECIFICATIONS FOR HIGH AMBIENT TEMPERATURE PERFORMANCE.
Risk: AT HIGH AMBIENT INTERIOR VEHICLE TEMPERATURES ABOVE140 DEGREES, THE AIR BAG MAY TEAR AND MALFUNCTION UPON DEPLOYMENT.
Fix: REPLACE THE AIR BAG MODULES WITH MODULES THAT MEET SPECIFICATIONS.

Percentile ranks against other compact cars in the catalog.
What stands behind each score for this car:
Owners have filed 40 complaints with NHTSA for this model-year, and visibility is the most reported area with 6 of them (15%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 91/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 83/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1991 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 75/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
