2020 GMC Terrain vs 2021 GMC Terrain
Two adjacent model years of the GMC Terrain, side by side. Every figure is a raw NHTSA/EPA count — not normalized by how many were sold.
Side by side: identical recall campaigns (2 each), and 2021 Terrain has fewer recorded owner complaints (34 vs 183). Both carry NHTSA crash ratings, and neither has EPA fuel-economy data in our dataset.
| Metric | 2020 GMC Terrain | 2021 GMC Terrain |
|---|---|---|
| Recall campaigns | 2 | 2 |
| Owner complaints | 183 | 34 |
| NHTSA investigations | 0 | 0 |
| NHTSA crash rating | Rated by NHTSA | Rated by NHTSA |
| EPA fuel economy | — | — |
Where these two actually differ
Both carry 2 recall campaigns, so recall history does not separate them. A campaign can still cover very different defects on each vehicle — read both records before treating the tie as equivalence.
2020 GMC Terrain has drawn 149 more owner complaints (183 against 34). Complaints are self-reported to NHTSA and scale with how many were sold, so treat the pattern of what owners report as more informative than the total.
Both have been crash-tested by NHTSA, so their star ratings are directly comparable — they were assessed under the same program in the same year.
Counts are raw NHTSA and EPA totals for each model year. They are not adjusted for how many of each vehicle were sold, so a high-volume model will tend to show more of everything — a larger complaint count is not by itself evidence of a worse car. Use the per-vehicle reports for the underlying records.
How to read this
- A green check marks the lower raw count — fewer recorded issues, not a declared winner.
- Complaint totals are not normalized by vehicle population; a big-seller shows more of everything.
- Where a rating or EPA record is absent, that is missing data — not evidence of safety.
