Best and Worst GMC Sierra Years: What the NHTSA Data Shows
Across the 13 GMC Sierra model years from 2010 to 2022 that have NHTSA data, the typical year has about 479 owner complaints on file. These are the extremes:
Fewest owner complaints
Complaint counts are unverified owner reports to NHTSA and rise with how many cars were sold and how long they have been on the road, so treat them as a pointer for what to inspect, not a reliability score. Model years after 2022 are left out because they have had little time to accumulate reports. Always check a specific car by VIN at nhtsa.gov/recalls.
