1990 BUICK RIVIERA
This model year
What the record shows
The 1990 Buick Riviera is a midsize car, and the 22nd model year of a nameplate NHTSA records from 1969 to 2000.
The EPA rated one configuration: a single 3.8-litre six-cylinder engine, front-wheel drive only, a single transmission, Automatic 4-spd and running on regular gasoline.
Combined fuel economy is 19 mpg.
The federal record holds 16 owner complaints 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.
