2012 Lexus IS problems: engine and transmission complaints and recalls
40% of relevant owner complaints filed with NHTSA on the 2012 Lexus IS are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Better than 53% of the 1,790 model years we track (2010–2023).
Excludes 26 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 15%).
Does the 2012 Lexus IS have engine problems?
Owner complaints say yes, as a model-year pattern. 6 of 15 relevant complaints filed with NHTSA about the 2012 Lexus IS concern the engine, transmission or fuel system (40%), and the largest group is filed under engine (3). For comparison, the 2011 scores 32%. 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.
