Brand-wide Lexus Problem Patterns

CT 200h and early IS models can suffer from EGR (Exhaust Gas Recirculation) clogging, leading to engine knocking and head gasket failure.
Older RX, GS, and LS models may experience brake actuator failure, which is a very expensive repair (often over £2,000).
Modern models (UX, NX Mk2, RX Mk5) are prone to 12V auxiliary battery drain, which can leave the car unable to start after just a few days of inactivity.
Infotainment systems on 2014–2019 models using the "Remote Touch" interface are often criticized for being difficult to use and prone to hardware glitches.
