Ford recalls over 550,000 pickup trucks in US after transmissions' glitch
Ford is recalling more than 550,000 pickup trucks in the US because the transmissions can unexpectedly downshift to first gear no matter how fast the trucks are going.
The recall covers certain F-150 pickups from the 2014 model year. Ford's F-Series pickups are the top-selling vehicles in the US.
Ford says in documents posted Tuesday by US safety regulators that the downshifting can cause drivers to lose control of the trucks, increasing the risk of a crash.
The recalls come after US auto safety regulators in March began investigating complaints that more than 540,000 Ford pickup trucks from 2014 can abruptly downshift to a lower gear and increase the risk of a crash.
Documents say the problem is caused by a lost signal between a transmission speed sensor and the powertrain control computer. There also could be corrosion and problems with connector pins.
Dealers will update the powertrain control software at no cost to owners, who will be notified by letters in early July.
