- A crack in the fuel pulsation damper may cause a fuel leak affecting the GS350 and GS450h from 2005-2015 models years.
- The sealing performance of the gasket seated within the fuel pressure sensor and the engine fuel delivery pipe might deteriorate over time. This is seen on the Lexus GS300 (2005 – 2007).
