Today, Ford Motor Company issued a recall for more than 900 Ford Focus Electric sedans.

The recall stems from a problem with the car’s transmission differential assembly.

Ford’s recall notice said that in certain vehicles, it is possible the differential pinion shaft could wear out, resulting in a shaft fracture that would cause the vehicle to lose motive power without warning while driving,

A worn pinion shaft could also affect the transmission park function without warning.

Either could increase the risk of injury or a crash, although Ford is not aware of any accidents or injuries linked to this issue.

To correct the defect, Ford dealers will install a new transmission differential assembly equipped with a friction-reducing coating on both the pinion shaft and pinion gear bores.

Affected vehicles include certain 2015-2016 Focus Electric vehicles built at the Michigan Assembly Plant, August. 20, 2015 through April 13, 2016, and Saarlouis Assembly Plant, February 28, 2016 through March 30, 2016.

Affected vehicles total 949, including 865 in the United States and 66 in Canada.

The Detroit automaker did not immediately announce an owner-notification schedule.
