The United States National Highway Traffic Safety Administration (NHTSA) has confirmed that the recall programme for faulty Takata airbag inflators will be expanded to include an additional 35 to 40 million units. The decision to do so comes following the safety agency’s confirmation of the root cause behind the inflators’ propensity to rupture.

The expanded recall means that all Takata ammonium nitrate-based propellant driver and passenger frontal airbag inflators without a chemical drying agent, also known as a desiccant, will be recalled. The lack of the drying agent, when subjected to moisture and heat, can cause the propellant within the inflator to be rendered unstable, and explode with excessive force when the airbag deploys, rupturing its container and spraying vehicle occupants with metal shards.

In the US, the defective inflators have been linked to ten deaths and more than 100 injuries. Other countries, including Malaysia, have reported similar cases as well. Recently, Honda Malaysia revealed that on two separate crashes in the country this year, Takata-made airbag inflators had ruptured, unfortunately leading to two fatalities.

This will add to Takata’s woes, where nearly 29 million inflators have already been recalled previously in the US. The company was also slapped with a record fine of USD$200 million and has since been abandoned by several carmakers including Honda, Mazda and Nissan.

According to the NHTSA, the recall expansion will be carried out across five phases between May 2016 and December 2019, based on the prioritisation of risk, determined by the age of the inflators and exposure to high humidity and fluctuating high temperatures that accelerate the degradation of the chemical propellant.

“The science clearly shows that these inflators become unsafe over time, faster when exposed to humidity and variations of temperature,” said NHTSA Administrator Mark Rosekindt. “This recall schedule ensures the inflators will be recalled and replaced before they become dangerous, giving vehicle owners sufficient time to have them replaced before they pose a danger to vehicle occupants. NHTSA will continue to evaluate all available research and will act quickly to protect safety.”
