1984 MERCURY TOPAZ
This model year
What the record shows
The 1984 Mercury Topaz is a compact car, and the 2nd model year of a nameplate NHTSA records from 1983 to 1998.
The EPA rated seven configurations: engines from 2-litre four-cylinder to 2.3-litre four-cylinder, two transmissions and running on diesel and regular gasoline.
Combined fuel economy ranges from 21 to 34 mpg depending on which one you have.
The federal record holds 10 owner complaints and 13 service bulletins for it.
Counts are reports, not rates. A complaint is something an owner chose to file; it is unverified and unadjusted for how many of these cars were sold, so the useful comparison is against other model years of the same car. Recalls and investigations carry more weight because a manufacturer or regulator acted on them.
Reading this report
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
