2017 GMC Terrain — should you buy one?

What owners love. What breaks at typical mileage. What people are actually paying. Then run the VIN through EstimateProof for $25 before you sign anything.

Why people love the 2017 GMC Terrain

The 2017 Terrain's 2.0-liter turbo engine makes 252 horsepower and pairs with a nine-speed automatic that feels responsive in city driving. Owners praise the upright seating position—easier to get in and out of than a sedan—and the cabin is quiet enough on the highway that you can hear yourself think. The all-wheel-drive system grips well in snow without eating fuel like a truck does.

Common complaints and known issues

The nine-speed transmission shows hesitation or jerking between gears starting around 70k–90k miles, often requiring a software update that doesn't always stick. Infotainment screen freezes or goes black are frequent complaints by 100k miles. At 120k–150k, some owners report timing chain rattle on cold starts, a sign the chain tensioner is wearing out and repair costs can hit $1,500–$2,000.

Typical asking price

Under 80k miles: $14,500–$17,500. 80k–120k: $11,500–$14,000. Over 120k: $8,500–$11,000. SLT and Denali trims command $2,000–$3,500 premiums over base SL. AWD adds $1,500–$2,000. Clean title and full service history can shift buyers toward the higher end of each band.

Ranges are typical 2026 asking prices, not appraisals. The actual fair offer depends on this specific car's title history, accident record, and open recalls — which is what EstimateProof tells you.
