Continental air bag defect could affect two million US vehicles.

Cars (2/9, Mays, 951K) reports that the NHTSA has posted notices “from German auto supplier Continental that some of its airbag control units – each of which controls all the airbags in a vehicle – are susceptible to corrosion in the components that power them.” NHTSA said the units were manufactured between 2006 through 2010 and “some 5 million cars could be involved, but Continental said that’s a global total.” Continental spokeswoman Mary Arraf said the problem “potentially impacts less than 2 million vehicles” in the US. The notice listed six automakers that sold affected vehicles in the US: Honda, Fiat Chrysler Automobiles, Mercedes-Benz, Mazda, Volkswagen Group and Volvo Trucks. Cars says that some, but not all, of the affected vehicles have been recalled while automakers determine which vehicles are impacted.
