Ford knows of one crash and one injury due to the problem.
The safety recalls, which affect model year 2018 Ford F-150, Expeditions, F-650 and F-750 vehicles with 10-speed and 6-speed automatic transmissions, follow reports of one injury related the problem, the company said. Expeditions included were made at the Kentucky Truck Plant between April 3, 2017 and January 30, and the F-650s and F-7502 at the Ohio Assembly Plant between April 25, 2017, and March 9.
Dealers will inspect the vehicles to ensure that the shift cable locking clip was properly installed and will secure the locking clip at no charge to the customer if it was not. The partially seated clip or a clip that becomes dislodged may allow the transmission to be in a gear that is different from the gear shift position selected by the driver, the automaker says.
Unintended movement of the vehicle may result if the parking brake is not applied. If missing, the 10-speed transmission over time could lose park function even when the instrument panel display and shifter show the vehicle is in park mode and without warning message or door chime. Ford said there may be no warning light or sign when the driver gets out of the vehicle, which could "result in unintended vehicle movement", meaning the auto could start rolling.
The recall involves approximately 347,425 vehicles in North America, with 292,909 in the United States and federalized territories, 51,742 in Canada and 2,774 in Mexico.
The company is also recalling more than 100 other vehicles for a missing transmission roll pin.
Ford is recalling about 350,000 trucks for a problem that could cause them to roll even after the driver shifts into park.
The company said it's not aware of any incidents related to the second recall.
