2016 GMC Terrain — Should You Buy One?
Typical asking price: $9,000–$14,000. There are 2 high-severity known issues you need to know before handing over a check.
Kestrel Take
The squared-off cousin of the Equinox, and the engine choice is everything. The oil-hungry 2.4L is the one to avoid; the 3.6L V6 sidesteps the problem. Otherwise a comfortable, quiet crossover that's cheap because it drove like an old design even when new.
What we checked
Reconciled against public records, 2026-09-25
NHTSA holds 152 owner complaints for the 2016 GMC Terrain, and 2 recall campaigns.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 32% of them are about one thing — glass, wipers and mirrors. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.
2 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Looked at and set aside: glass, wipers and mirrors (49) — 49 complaints about glass, wipers or mirrors; usually annoying rather than expensive.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
