2018 Lexus RX: engine and transmission complaints

ELEVATED COMPLAINT SIGNAL
37%
16 of 43 relevant owner complaints are about the engine, transmission or fuel system

37% of relevant owner complaints on the 2018 Lexus RX are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.

Better than 58% 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: 35%).
