The quality index for GMC is calculated from reliability data across 80 vehicle configurations from 5 different models. The index considers:
- NHTSA recall counts, weighted by severity
- NHTSA complaint counts, weighted by crashes, injuries, and deaths reported
- EPA fuel-economy data where available
- A brand-tier baseline used to steady scores when a specific model-year has little NHTSA history
Higher scores indicate better predicted quality and reliability. The quality index is refreshed as NHTSA publishes new recall and complaint data.
