Lexus GS300 ProblemsExcess Engine Oil Consumption
Sludge can build up in the engine because Lexus did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary.

Lexus GS300 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 plastic pad embedded in the floor carpet may interfere with the operation of the accelerator pedal. As a result, it may become stuck in a partially open position. A stuck accelerator can result in unintended vehicle speed, increasing the risk of a crash. Dealers will modify the plastic pad in the floor carpet. No owner notification schedule has be set at this time.
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.
