What is the 2006-2007 Lexus GS Aluminum Fuel Rail Internal Corrosion from Ethanol Fuel (Recall 09V020000)?

Early S190 cars (2006-2007 GS) were built with aluminum fuel delivery pipes. Ethanol-blended gasoline with low moisture content attacks the internal surface of the aluminum rail. The corrosion progresses until it eats a pinhole through the pipe wall, at which point gasoline leaks… Repairs typically run $0-$0. Severity: high.

What is the 2006-2012 Lexus GS Dashboard Melting and Sticky Surface?

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… Severity: medium.

What is the 2006-2015 Lexus GS Power Steering Rack Seal Leak?

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 ra… Repairs typically run $800-$2,000. Severity: medium.

What is the 2006-2020 Lexus GS Front Timing Chain Cover and Cam Housing Oil Leak - 2GR-FSE (FIPG Sealant Failure)?

The 2GR family V6 - including the 2GR-FSE fitted to the S190 GS 350 / GS 450h and the L10 GS 350 - seals its front timing chain cover and cam housings with FIPG (formed-in-place gasket) sealant rather than a solid gasket. Over years of heat cycling the sealant hardens, shrinks an… Repairs typically run $2,400-$4,000. Severity: medium.
