2018 Toyota Highlander problems: engine and transmission complaints and recalls
46% of relevant owner complaints filed with NHTSA on the 2018 Toyota Highlander are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 58% of the 1,790 model years we track (2010–2023).
Excludes 24 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 42%).
Does the 2018 Toyota Highlander have transmission problems?
Owner complaints say yes, as a model-year pattern. 112 of 243 relevant complaints filed with NHTSA about the 2018 Toyota Highlander concern the engine, transmission or fuel system (46%), and the largest group is filed under power train (67). For comparison, the 2017 scores 54% and the 2019 scores 68%. 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.
