Lexus, a Toyota Brand, has recalled over 200,000 units due to faulty fuel delivery components. The models effected are the Lexus GS 300/50, Lexus IS 250/350, and the LS 460/460L models.
The source of the problem comes from ethanol fuel, which some have a low moisture content that causes corrosion to the Lexus components. The corrosion could eventually lead to a pin hole, leaking fuel, with potential for fire.
