They are included in vehicles built by General Motors, Ford, Stellantis, Tesla, Toyota, Hyundai, Kia, Mercedes-Benz, BMW and Volkswagen. NHTSA did not release exact models containing the air bags, saying that will be determined by the manufacturers. It also did not give an estimate for how many vehicles contain the air bags, since most vehicles have multiple air bags. The agency did not say how many cars may have more than one of the air bags it wants recalled. The number of air bags still in use is less than the 67 million that NHTSA estimated earlier this year.
