2012 Hyundai Sonata problems: engine and transmission complaints and recalls
54% of relevant owner complaints filed with NHTSA on the 2012 Hyundai Sonata are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 72% of the 1,790 model years we track (2010–2023).
Excludes 283 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 45%).
Does the 2012 Hyundai Sonata have engine problems?
Owner complaints say yes, as a model-year pattern. 693 of 1,274 relevant complaints filed with NHTSA about the 2012 Hyundai Sonata concern the engine, transmission or fuel system (54%), and the largest group is filed under engine (567). For comparison, the 2011 scores 43% and the 2013 scores 55%. 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.
