All 1 Known Issues
On the 2010-2023 Lexus GX 4.6L 1UR-FE, the Kinetic Dynamic Suspension System (KDSS) on the GX460 develops hydraulic fluid leaks from the stabilizer bar actuators and hydraulic lines. Leaks cause the KDSS warning light to illuminate and the system to become inoperative, resulting in increased body roll and a less controlled ride. The front actuators are the most common failure point.
Common Symptoms
- KDSS warning light on dashboard
- Hydraulic fluid leak under vehicle
- Increased body roll in corners
- Clunking noise from suspension over bumps
- Visible fluid on stabilizer bar actuators
How to Fix
Replace the leaking KDSS actuator(s) and hydraulic lines. Refill and bleed the system with the correct Toyota KDSS fluid. Both front and rear actuators should be inspected even if only one is leaking. Some owners disconnect the KDSS system and install conventional sway bars.
