About this comparison
What GMC Terrain years have the most complaints?
No GMC Terrain model year drew more than twice the typical complaint rate among the 18 model years compared. The highest was 2020.
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.
