About this comparison
What Oldsmobile Alero years have the most complaints?
No Oldsmobile Alero model year drew more than twice the typical complaint rate among the 6 model years compared. The highest was 2000.
Is this a reliability rating?
No. These are counts of unverified owner complaints to NHTSA. They are not adjusted for how many cars were sold, so a popular year can collect more complaints. Use them to find patterns, then read the reports.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
