Ford Motor Co. is recalling 177,264 2016 Ford F-150 and 2016 Ford Explorer vehicles in the U.S. because the front power seats may not adequately protect occupants during a collision, according to the automaker.

“In affected vehicles, the upper left-hand pivot bolt for the front power seat adjuster may loosen or fall out,” Ford explained in a released statement about the recall. “A front seat cushion with a missing upper left-hand pivot bolt may experience increased movement in a crash and not properly restrain occupants, increasing the risk of injury.”

Ford noted, however, that it isn’t aware of any related accidents or injuries.

To fix the problem, dealers will measure the torque of the power seat track upper pivot link bolt. If the bolt passes the torque inspection, dealers will remove and clean the bolt, apply new threadlock, and reinstall the bolt to the specified torque. This repair will complete the recall.

But if the bolt fails the torque inspection, dealers will add threadlock and reinstall the bolt as an interim repair until the final remedy is available. The final repair will include replacement of the lift link with new bushings and fasteners. All repairs will be performed at no cost to the customer.

In addition to the vehicles recalled in the U.S., 22,620 vehicles will be recalled in Canada and 2,390 will be recalled in Mexico for the same issue. The Ford reference number for this recall is 17S40.
