The sometime fatal flaw


That was embraced by corporations around the world because it was cheaper. And despite proven hazard to their customers, they were reluctant to give it up. I am referring to the Takata airbag inflator that has been recalled by just about every mass market carmaker, it was that ubiquitous.
In the late 1990s, General Motors got an unexpected and enticing offer. A little-known Japanese supplier, Takata, had designed a much cheaper automotive airbag.

G.M. turned to its airbag supplier — the Swedish-American company Autoliv — and asked it to match the cheaper design or risk losing the automaker’s business, according to Linda Rink, who was a senior scientist at Autoliv assigned to the G.M. account at the time.

But when Autoliv’s scientists studied the Takata airbag, they found that it relied on a dangerously volatile compound in its inflater, a critical part that causes the airbag to expand.

“We just said, ‘No, we can’t do it. We’re not going to use it,’” said Robert Taylor, Autoliv’s head chemist until 2010.

Today, that compound is at the heart of the largest automotive safety recall in history. At least 14 people have been killed and more than 100 have been injured by faulty inflaters made by Takata. More than 100 million of its airbags have been installed in cars in the United States by General Motors and 16 other automakers.

Details of G.M.’s decision-making process almost 20 years ago, which has not been reported previously, suggest that a quest for savings of just a few dollars per airbag compromised a critical safety device, resulting in passenger deaths. The findings also indicate that automakers played a far more active role in the prelude to the crisis: Rather than being the victims of Takata’s missteps, automakers pressed their suppliers to put cost before all else.

“General Motors told us they were going to buy Takata’s inflaters unless we could make a cheaper one,” Ms. Rink said. Her team was told that the Takata inflaters were as much as 30 percent cheaper per module, she added, a potential savings of several dollars per airbag. “That set off a big panic on how to compete.”
But have no fear ammonium nitrate lovers, Takata has a new and improved version of the same inflator that it says is safe and won't kill you when it goes off. Now, don't you feel better?
