NBC News - BMW has agreed to demands from the government to replace driver's-side air bags across the entire U.S.
The National Highway Traffic Safety Administration has been pushing companies to recall older cars with air bag inflators made by Takata Corp. They can explode with too much force and spew shrapnel at drivers and passengers.
At least five deaths have been blamed on Takata inflators.
The decision affects 140,000 BMW 3 Series cars made between January 2004 and August 2006. It says no problems with BMW vehicles have been reported.
Earlier this year the company took about 574,000 cars off the market in the U.S. Several automakers have been slow to expand the recall. Ford Motor Co. joined the list last week, and was quickly followed by Chrysler.
BMW is the last automaker to agree to replace air bags in all affected cars nationwide. About 15 million cars have been recalled in the U.S. in total.
Initial recalls were limited to states with high levels of humidity, as the NHTSA says the air bag inflator propellant, ammonium nitrate, can burn faster than designed if exposed to prolonged airborne moisture.
When that happens, the propellant can blow apart a metal canister meant to contain the explosion.
