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.
The warning includes 33,428 Ranger and 1,955 Mazda B-Series small pickups from 2006 model year, according to both companies.
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. Parts for the repairs already are available.
Rangers added to the do-not-drive list were built between August 5 and December 15, 2005.
The agency urged owners of all the recalled Rangers and B-Series trucks to call a dealer and get repairs made now.
Takata uses ammonium nitrate to create a small explosion to inflate air bags. But the chemical can deteriorate and burn too fast, blowing apart metal canisters and hurling shrapnel into drivers and passengers. At least 22 people have died and more than 180 have been hurt because of the problem.
