2 known faults
For the 2023 RX 350h, the first category of complaints recorded by CarComplaints is electrical, led by a flat battery after a period of immobilisation; Auto Reliability Index also cites the 12 V battery as the most frequent problem with hybrids. Owner testimonies, mostly North American: no manufacturer confirmation in the sources consulted.
French campaign 24SD-065 (around 1,868 cars): on part of the 2022-2023 production, including RX 450h+ and 500h, the front camera housings may have been poorly soldered; water can get in over time and cause a short circuit. The network checks the soldering and replaces the camera and its housing if necessary. Check the serial number with a Lexus dealership.
Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.
