US auto safety regulators on Tuesday said their estimate for the millions of vehicles affected by the Takata air bag recall will likely be revised because cars with two front air bags were double-counted.
Mark Rosekind, administrator of the National Highway Traffic Safety Administration, said in written testimony to the Senate Commerce Committee that regulators are waiting for automakers to provide information including the number of inflators that must be replaced more than once.
The Obama administration last month said it was doubling the number of vehicles involved to nearly 34 million, making the Takata recall the largest in US history. But a Reuters analysis found the number could prove to be less than half that due to vehicles with more than one air bag.
On Tuesday, Rosekind said there are about 32 million defective inflators on US roads that need to be replaced.
