Takata, the parts supplier that furnished automakers with millions of extremely dangerous airbag inflators, was forced to issue another recall last week. Considering the hundreds of millions of units already recalled by the company, another 2.7 million is a drop in the bucket. But there’s a slight problem, as these newly recalled inflators are devices that have already been replaced.

In 2015, regulators specified Takata had until the end of 2019 to ensure its replacement airbag inflators were safe. With the “fixed” units now under scrutiny, automakers may be liable for the supplier’s wrongdoing as the millions upon millions of recalled inflators would need to be replaced for a second time. The current recall was prompted after the U.S. National Highway Traffic Safety Administration found the drying agent added specifically to combat the moisture that degrades the ammonium nitrate compound wasn’t effective.

“Absent proof that the other desiccated inflators are safe, they will also be subject to recall,” the NHTSA said in a statement last week.

Takata stated it has produced roughly 100 million replacement inflators containing drying agents. The 2.7 million recalled last week used calcium sulfate while the rest used zeolite.

According to Reuters, automakers have been burdened with a significant portion of the estimated $10 billion cost of replacing the faulty inflators. They’d also be liable in the event of NHTSA deciding Takata failed to adequately address the safety issues with the remaining recalled units. At this point, there isn’t much more that can be done with the Japanese supplier. Takata filed for bankruptcy in June and has since been purchased by Michigan-based Key Safety Systems for $1.6 billion.

“The automakers … and Takata — they all know that this is a future issue,” said Scott Upham, chief executive at Valient Market Research, whose clients consist of several auto parts suppliers. “But I think everybody is concerned about the near-term issues, and the financial arrangements of the bankruptcy.”

Obviously, the most pressing short-term danger consists of additional harm to motorists. So far, the faulty inflators have contributed to at least 17 known fatalities and countless injuries.

Takata is the only airbag manufacturer to use ammonium nitrate as a propellant in its systems. It’s unlikely that will ever change, due to the compound’s volatile tendencies. Takata’s inflators can rupture the airbag, spraying vehicle occupants with shrapnel, after the compound is exposed to moisture or high temperatures for prolonged periods. While the drying agents used appear to have stabilized the propellant somewhat, fears remain that it’s simply too volatile to be used in inflators and will require removal if the NHTSA isn’t satisfied.

Honda is likely to be the company most hurt by a second round of recalls, since it used more of Takata’s inflators than any competitor. But it won’t be the only one to suffer. Toyota, Nissan, General Motors, Ford, Fiat Chrysler, Mazda, Subaru, Jaguar Land Rover, Mitsubishi, Tesla, Fisker, Ferrari, McLaren, BMW, Mercedes-Benz, and Volkswagen Group have also all been affected by the recall.
