NHTSA Probes 725k Ford, Mercury Vehicles for Stalling

The National Highway Traffic Safety Administration (NHTSA) opened an investigation on February 21 that affects almost 725,000 vehicles from Ford and Mercury.

Affected vehicles include the Ford Escape and Fusion as well as the Mercury Mariner and Milan. The investigation centers around an issue with the throttle body in those cars that, according to NHTSA documents, has been reported to cause engine stalling and surging.

Error codes in the described vehicles suggest that the throttle body is either stuck open or closed. The NHTSA office of Defects Investigation (ODI) has received 123 complaints so far while Ford reports receiving 1,472.

A faulty circuit board seems to be the cause of the problem because they could lead to “a lack of continuity in the throttle position sensor circuit.”

Model years affected include the 2009 to 2010 Escape and Escape Hybrid as well as the Mercury Mariner and Mariner Hybrid, the 2010 and 2011 Fusion and Mercury Milan.
