2012 GMC Acadia problems: engine and transmission complaints and recalls
37% of relevant owner complaints on the 2012 GMC Acadia are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.
Better than 58% of the 1,790 model years we track (2010–2023).
Excludes 58 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 30%).
Does the 2012 GMC Acadia have transmission problems?
More than most. The pattern is elevated rather than severe. 91 of 244 relevant complaints filed with NHTSA about the 2012 GMC Acadia concern the engine, transmission or fuel system (37%), and the largest group is filed under power train (43). For comparison, the 2011 scores 37% and the 2013 scores 45%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. 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.
