DETROIT, Michigan — The problem of exploding crash-bags could extend beyond Japanese manufacturer Takata Corp.

US safety regulators are investigating inflators made by Atlantic Research Corporation Automotive Inc. installed in about 420 000 older Fiat Chrysler Town and Country minivans and another Kia Optima midsize sedans.

The probe, revealed in documents posted Tuesday (July 14) by the National Highway Traffic Safety Administration, comes just weeks after Takata agreed to recall 33.8-million inflators in the US in the largest automotive recall in American history. At least eight people have been killed worldwide by flying shrapnel from Takata inflators and more than 100 injured.


The safety agency said it received a complaint in December 2014 about a 2009 incident in a 2002 Chrysler minivan but determined it was an isolated case involving an Arc driver's side inflator.

Then in June 2015, Kia told the agency about a lawsuit involving a 2004 Optima with an Arc driver's side inflator, so the agency decided to open an investigation. Both cases are the only known incidents involving Arc inflators in vehicles made by either automaker.

NHTSA investigators wrote in the documents: "At the present time it is unknown if there is a common root cause in these incidents. (The agency) is opening this investigation in order to collect all known facts from the involved suppliers and vehicle manufacturers."

The agency said two people were hurt in the incidents but no one was killed.

Knoxville, Tennessee-based Arc said in a statement that it is cooperating in the probe and pointed to a 60-year record of "serving our customers with products that meet the most stringent global safety standards."


Fiat Chrysler said it no longer uses the inflators that are being investigated. Both it and Kia said they are cooperating.

NHTSA said in documents that Arc makes inflators that are used by other companies in their crash-bag systems. The inflators use an inert gas to fill the crash-bag which is supplemented by an ammonium nitrate-based propellant. A preliminary analysis of the Chrysler minivan system showed that the path for the inflator gas to exit the inflator may have been blocked by an unknown object, the document said.

In the Takata cases, ammonium nitrate is the main propellant, and it can become unstable over time when exposed to high humidity and temperatures. The chemical can burn too fast and blow apart a metal inflator canister. Automakers, NHTSA and Takata are trying to find exactly what causes the malfunctions.


Documents show that the Chrysler minivan incident happened on January 29 2009, in Ohio. A man complained to NHTSA that his wife was injured by flying shrapnel when the minivan collided with a snowmobile while she was turning into their driveway and the crash-bag deployed. "Most of the shrapnel went into her chest, with the crash-bag plate breaking apart, striking her in the chin, breaking her jaw in three places," wrote the man, who was not identified. "If it hadn't been for a great ambulance crew, she would have bled to death."

According to NHTSA, Arc made inflators for Delphi Corp crash-bags that were sold to Kia and used in Optimas, and it made inflators for Key Safety Systems crash-bags sold to Chrysler and used in minivans.

Delphi said in a statement that it will respond to any NHTSA inquiries. Arc inflators were used in some of its crash-bag assemblies before the company sold its crash-bag business in 2010, the statement said.

Key said it would support the investigation.
