TOYOTA issued a recall on the GS 300GS 350,IS 250, and IS 350 models

On certain GS 300, GS 300 AWD, GS 350, IS 250, IS 250 AWD and IS 350 vehicles, the fuel pressure sensor connected to the engine fuel delivery pipe may not have been sufficiently tightened during vehicle assembly. Should the pressure sensor loosen, fuel could leak past a gasket used in the connection between the sensor and pipe, and through the threaded portion of the sensor. Fuel leakage, in the presence of an ignition source, could result in a fire causing property damage and/or personal injury. Correction: Dealers will inspect for fuel leakage from the threaded portion of the fuel pressure sensor. If there are no signs of a fuel leak, the fuel pressure sensor will be tightened to specifications. If a fuel leak is confirmed, the gasket between the sensor and the fuel delivery pipe will be replaced, and the sensor will be tightened.
