The United States National Highway Traffic Safety Administration is investigating 725,000 Ford Fusion and Mercury Milan sedans as well as Ford Escape and Mercury Mariner crossovers after receiving reports of possible fuel system problems that could result to a sudden loss of engine power.
NHTSA's Office of Defects Investigation disclosed that owners of the Ford sedans and crossovers have reported incidents of electronic throttle body failure while driving, causing the engine to suddenly lose power.
According to the USA Today, the probe covers 2009 through 2011 models of the Escape, Mariner, Fusion and Milan. Ford said that it is cooperating fully with the government on the investigation. NHTSA's initial report on the probe said ODI had received 123 complaints and Ford had received 1,472 complaints. NHTSA said that 27,505 warranty claims had been filed relating to the "repair or replacement of the subject component." The electronic throttle body is one of the components of the fuel delivery system of an engine.
