2015 Lexus RX: engine and transmission complaints

ELEVATED COMPLAINT SIGNAL
37%
22 of 60 relevant owner complaints are about the engine, transmission or fuel system

37% of relevant owner complaints on the 2015 Lexus RX are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.

Better than 59% of the 1,230 model years we track (2010–2023).

Excludes 7 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 33%).

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 2015

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.
