2012 GMC Terrain: engine and transmission complaints

HIGH COMPLAINT SIGNAL
59%
195 of 330 relevant owner complaints are about the engine, transmission or fuel system

59% of relevant owner complaints filed with NHTSA on the 2012 GMC Terrain are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.

Worse than 79% of the 1,230 model years we track (2010–2023).

Excludes 40 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 53%).

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

Cleaner alternatives

Other compact SUVs with no elevated signal

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.
