2019 GMC Terrain problems: engine and transmission complaints and recalls
55% of relevant owner complaints filed with NHTSA on the 2019 GMC Terrain are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 74% of the 1,790 model years we track (2010–2023).
Does the 2019 GMC Terrain have engine problems?
Owner complaints say yes, as a model-year pattern. 99 of 185 relevant complaints filed with NHTSA about the 2019 GMC Terrain concern the engine, transmission or fuel system (55%), and the largest group is filed under engine (69). For comparison, the 2018 scores 43% and the 2020 scores 45%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
