2023 Lexus LM

The large, heavy electric sliding passenger doors on the Lexus LM operate on precision upper and lower guide tracks equipped with optical anti-pinch and obstacle detection sensors. In the UK winter environment, road grime, salt spray, and leaf debris accumulate in the lower sill track runners, causing the nylon rollers to drag and emit grinding or squeaking noises. Furthermore, the sensitive anti-pinch sensors can trigger false reversals on slight inclines or in gusty winds, preventing the doors from latching fully without manual assistance.

Symptoms: Sliding side doors stutter, shudder, or screech while opening or closing along the guide tracks, Door automatically reverses open halfway through closing cycle without any visible obstruction...

Est. repair cost: £200–£550

In both four-seat and seven-seat UK LM models, rear cabin comfort features (including seat climate, ambient lighting, audio zones, sunshades, and the 48-inch screen partition) are managed via removable smartphone-style touchscreen controllers housed in the rear armrests. Owners frequently report connection timeouts, unresponsive touchscreens, and software desynchronisation between the remotes and the central vehicle body ECU. This leaves rear occupants temporarily unable to adjust seating angles, alter climate zones, or lower the privacy partition until an infotainment system reboot is executed.

Symptoms: Rear armrest remote control touchscreens become unresponsive or display Connecting indefinitely, Privacy glass partition refuses to switch between transparent and frosted states...
