2019 Lexus RX: engine and transmission complaints

HIGH COMPLAINT SIGNAL
51%
33 of 65 relevant owner complaints are about the engine, transmission or fuel system

51% of relevant owner complaints filed with NHTSA on the 2019 Lexus RX are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.

Worse than 66% of the 1,230 model years we track (2010–2023).

Excludes 3 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 49%).

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

Same car, a better year

Other luxury SUVs with no elevated signal in 2019

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.
