All Known Issues

Power Sliding Door Track Roller Noise and Obstacle Sensor Sensitivity

ModerateBodywork & Rust

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.

Est. Repair Cost: £200–£550
Warning Signs:

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, Door Open warning lamp remains lit on the digital instrument cluster after closing, Electric soft-close motor fails to pull the rear door latch flush with the bodywork

What to Inspect:
  • Inspect the lower sliding door channel in the door sill for road dirt buildup, grit, or damaged rubber seals
  • Test electric closing of both sliding doors on both flat ground and a moderate slope
  • Check that the soft-close cinching latch pulls the door tight and silent against the B-pillar seals

Rear Cabin Control Tablet Desynchronisation and Software Glitches

MinorElectrics & Electronics

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.

Est. Repair Cost: £0–£400
Warning Signs:

Rear armrest remote control touchscreens become unresponsive or display Connecting indefinitely, Privacy glass partition refuses to switch between transparent and frosted states, Rear ottoman leg rests fail to respond to touch commands or stop mid-travel, Rear climate temperature display desynchronises from the actual air vent output temperature

What to Inspect:
  • Dock and undock both rear console remotes, testing every menu item including seats, shades, and screen
  • Toggle the electrochromic frosted privacy partition multiple times to ensure immediate transition
  • Confirm with the dealer whether the latest rear comfort ECU software updates have been installed

Buying Tips for 2024–2026 Lexus LM

  • Test every electrical feature in the rear passenger cabin using the dual smartphone-style controllers, including the ottoman leg rests, massage functions, and heated armrests.
  • On four-seat models, raise and lower the central privacy glass partition and toggle the electrochromic glass frosting feature to verify seamless operation.
  • Inspect the rear multi-link suspension and undertrays for scrape damage, as the LM long 3,000mm wheelbase makes it susceptible to grounding on high UK traffic-calming cushions.
  • Check both powered sliding side doors and their child safety sensors; ensure the doors glide smoothly along their tracks without sticking or reversing prematurely.
  • Verify that the vehicle has been serviced strictly on schedule within the Lexus dealer network to preserve the rolling 10-year/100,000-mile Lexus Relax warranty.
