It seems like this story never gets out of the news. The defective Takata airbag has recently killed a 10th person in the United States and now the NHTSA is recalling another 5 million vehicles. One of the largest recalled models is the 2004-2006 Ford Ranger. There have been 391,000 recalled within the last few days amidst the 10th death from a Takata airbag that exploded in a 2006 Ford Ranger.
According to NBC News (https://www.nbcnews.com/), other automakers are expected to announce more recalls soon as the Takata inflator mess continues to grow. It now covers 14 auto and truck makers and totals about 24 million vehicles. The National Highway Traffic Safety Administration says the number of recalls is likely to expand further.
Takata uses the chemical ammonium nitrate to cause a small explosion that creates gas and inflates air bags in a crash. But the chemical can deteriorate over time when exposed to high heat and humidity and burn too fast, blowing apart a metal canister designed to contain the explosion.
