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, Toyota Land Cruiser, 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.

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.

Typical repair cost:$400 - $1,500
