Ford Recalls 1.4M F-150 Trucks

The recall affects vehicles from the 2015-2017 model years equipped with six-speed automatic transmissions.

A software error can cause the transmission to suddenly shift into first gear regardless of speed, potentially causing the rear wheels to lock up.

Ford is advising owners to visit their dealers for a software update that will remedy the problem.

This massive recall adds to the automaker's recent quality control challenges and has prompted a federal investigation into the safety of the popular truck line.
