On the 2007-2017 Lexus LS, the pneumatic air suspension system on the LS460 and LS600h develops leaks in the air springs, causing the vehicle to sag overnight or drop on one corner. The air compressor runs excessively to compensate for leaks and eventually burns out. Complete air suspension failure leaves the car sitting on the bump stops.

This issue also affects: Lexus LX, Lexus GS

Common Symptoms

  • Vehicle sags on one corner overnight
  • Compressor runs constantly or excessively
  • Suspension warning light on dashboard
  • Rough ride quality with bottoming out
  • Vehicle sits noticeably lower than normal

How to Fix

Replace failed air struts with new OEM or aftermarket units from Arnott or Suncore. Replace the compressor if it no longer maintains pressure. For a permanent fix, some owners convert to conventional coilover suspension using kits from Strutmasters or BC Racing, which eliminates future air suspension issues.

On the 2007-2017 Lexus LS, the adaptive self-leveling HID headlight system fails due to deterioration of the headlight level sensors mounted at the front and rear suspension. The sensors develop internal failures from exposure to road debris and moisture, causing the headlights to aim incorrectly or trigger warning lights. Replacement sensors are expensive OEM-only parts.

This issue also affects: Lexus GS

Common Symptoms

  • Headlight leveling warning message on dashboard
  • Headlights pointing too high or too low
  • Headlights not adjusting when vehicle is loaded
  • AFS (Adaptive Front-lighting System) warning light

How to Fix

Replace the failed headlight leveling sensor(s). There are typically 3-4 sensors on the LS — two front and one or two rear. Use OEM sensors as aftermarket alternatives have poor fitment. Recalibrate the headlight system with a Lexus diagnostic scan tool after replacement.

Owner tips & cautions

  • TipBefore replacing sensors, check the sensor link rods first — they are plastic and break easily. A broken link rod is a $20 fix versus $300+ for a sensor.
