Ford Motor Co. is recalling 48,421 2017 Ford F-250 gasoline-powered 6.2-liter pickup trucks in the U.S. because they’re at risk for unintended movement while in park.

Drivers should use the parking brake at all times when shifting into park to keep the truck stationary, Ford advised in a released statement about the recall.

“In the affected vehicles, a damaged park rod actuating plate might not achieve mechanical park within the automatic transmission after the driver moves the shift lever to park,” Ford said. “If the parking brake is not applied, this could result in unintended vehicle movement with the gear selector in park without warning, increasing the risk of injury or crash.”

Ford noted, however, that the company isn’t aware of any accidents or injuries associated with this issue.

Ford dealers will inspect and replace the park rod actuating plate as necessary. There will be no charge for this service.

This safety compliance recall involves trucks built at Kentucky Assembly Plant from Oct. 9, 2015, to March 30 of this year.

Ford is also recalling 4,143 F-250 trucks in Canada for the same problem. The Ford reference number for this recall is 17C06.
