2015 Acura TLX problems: engine and transmission complaints and recalls
71% of relevant owner complaints filed with NHTSA on the 2015 Acura TLX are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 92% of the 1,790 model years we track (2010–2023).
Excludes 12 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 68%).
Does the 2015 Acura TLX have transmission problems?
Owner complaints say yes, heavily, as a model-year pattern. 234 of 330 relevant complaints filed with NHTSA about the 2015 Acura TLX concern the engine, transmission or fuel system (71%), and the largest group is filed under power train (160). For comparison, the 2016 scores 56%. 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.
