2020 CHEVROLET IMPALA
This model year
What the record shows
The 2020 Chevrolet Impala is a large car, and the 63rd model year of a nameplate NHTSA records from 1958 to 2020.
The EPA rated two configurations: a single 3.6-litre six-cylinder engine, front-wheel drive only, a single transmission, Automatic (S6) and running on regular gasoline.
Combined fuel economy is 22 mpg.
NHTSA's best overall crash rating for this model year is 5 out of five stars.
The federal record holds 15 owner complaints and 410 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.
