Ford and Mazda are adding more than 35,000 pickup trucks in North America to a list of vehicles that should not be driven because they have Takata air bag inflators with a high risk of exploding.

Ford, which made the B-Series for Mazda, found test results showing that the trucks had inflators that ruptured or recorded high internal pressure readings, spokeswoman Elizabeth Weigandt said Monday.

The companies and the U.S. National Highway Traffic Safety Administration said dealers will tow the pickups to service bays to replace the faulty inflators and provide loaner vehicles.

The agency has asked Ford, Mazda and Takata to focus testing on inflators built outside that 2005 production range "to ensure that other vehicles do not need to be included," the statement said.

Steve Mollohan, 56, of the Hedgesville, West Virginia, area died July 1 in nearby Martinsburg, about 80 miles northeast of Washington, D.C., according a Pittsburgh-based law firm representing the family.

After some investigation, the company determined that the truck's inflator was made on the same day as one that exploded and killed a South Carolina man driving a Ranger in 2015.

The recall came after the government announced the December 2015 death of Joel Knight, 52, of Kershaw, South Carolina, that was caused by a Takata air bag inflating in his 2006 Ranger.
