On the 2006-2012 Lexus GS, the GS dashboard suffers from the same melting and sticky surface defect as other Lexus models of this era. Heat exposure causes the dashboard material to chemically degrade, resulting in a shiny, tacky surface that creates dangerous glare on the windshield. This was a widespread issue across the Lexus lineup.
Common Symptoms
- Dashboard surface becomes sticky to touch
- Reflective glare on windshield from melted dashboard
- Material cracking and peeling
- Chemical smell from dashboard in warm weather

On the 2006-2015 Lexus GS, the power steering rack develops internal seal leaks that cause power steering fluid loss. The leak typically appears at the inner tie rod boots where fluid seeps past the rack seals. Low fluid levels lead to increased steering effort and pump whining noise, and eventually the rack must be replaced.
Common Symptoms
- Power steering fluid leaking from rack area
- Whining noise when turning steering wheel
- Increased steering effort especially at low speed
- Power steering fluid level drops
- Fluid-soaked inner tie rod boots
How to Fix
Replace the power steering rack assembly. Remanufactured racks are available from Maval and Cardone at significant savings over new OEM. Perform a complete power steering fluid flush after installation. Inspect tie rods and replace if worn.
