The Japanese automaker said in documents posted today by US and Canadian safety regulators that it is recalling nearly 503,000 cars to fix driver's air bags and 35,000 small pickup trucks to fix passenger air bags.
Affected models with potentially faulty driver's air bags are the 2003-2008 Mazda 6, 2006 to 2007 MazdaSpeed 6 and the 2004 to 2008 RX-8. The company also is recalling 2004-2006 B-Series pickup trucks to replace passenger side inflators.
The vehicles are equipped with air bag inflators made by Takata Corp. Of Japan that can explode with too much force, spewing shrapnel into the passenger compartment. Six people have been killed and more than 100 injured because of the problem.
Last month Takata and the US government agreed to double the number of inflators it recalled to 33.8 million. The increase made it the largest auto recall in US history, according to the agency. Eleven affected automakers are gradually announcing makes and models affected by the expansion.
