Lexus GS450h RecallsPotential Fuel Leak
Due to the remnants of anti-corrosion plating, a fuel leak may develop from where the fuel pressure sensor is attached to the fuel delivery pipe. Any fuel leak always increases the risk of a fire. Dealers will clean and reseal the area of the fuel pressure sensor to correct this concern.
The fuel pressure sensor monitors fuel pressure for optimum engine performance and emission controls. Lexus has found that some of these sensors can loosen from the fuel line, which may cause the sealing gasket to leak fuel. To prevent this from occurring in the future, your Lexus dealer will ensure that these sensors are properly fastened. No schedule of owner notification is available at this time.
Toyota is recalling 2000–2008 Lexus models due to micro-foreign objects in the valve spring that can cause it to break. This could cause the engine to fail suddenly, while the vehicle is in motion, increasing the risk of a crash. Toyota will notify owners and dealers will repair the vehicles free of charge.
