Most of the companies said NHTSA had determined the regions affected, when asked why other humid areas were not covered.However, Honda is also recalling affected vehicles in Alabama, Georgia, Louisiana, Mississippi, South Carolina and Texas.Most of the automakers have not determined the number of vehicles affected, but NHTSA previously estimated in documents that did not list Ford and BMW that more than 1 million vehicles could be covered by the issue."Based on the limited data available at this time, NHTSA supports efforts by automakers to address the immediate risk in areas that have consistently hot, humid conditions over extended periods of time," NHTSA said in a statement.The safety agency, which said the recalls burberry were influenced by a probe into six reports of air bag ruptures in Florida and Puerto Rico, added it is gathering additional information and will take action based on its findings.Monday's global recalls by Honda, Mazda and Nissan follow Toyota's recall last burberry week.Short of Takata replacement parts, the automakers burberry said they would turn off air bags in Japan as customers bring recalled vehicles into dealerships judging that an inoperable passenger side air bag is safer than a potentially defective one.In the United States, NHTSA opened a probe earlier this month on whether Takata inflators made after 2002 are prone to fail, and burberry whether driving in high humidity contributes to the risk of air bag explosions.In a June 11 letter to the NHTSA, Takata said it would support "regional campaigns" to replace certain driver side air bag inflators made burberry between January 2004 and June 2007, as well as certain passenger side inflators made between June 2000 and July 2004.
