ARC Automotive, a closely held maker of air-bag inflators based in Knoxville, Tennessee, said in an e-mailed statement it has been notified about the defect investigation and is cooperating.

Safety, security

“We will continue to put our focus where it should be: on the safety and security of drivers,” according to the company, which was formed in 1949 as Atlantic Research Corp. to develop propellants for the Defense Department. It licensed inflator technology to carmakers beginning in 2002, according to its website.

Fiat Chrysler also is cooperating with the agency’s investigation, said Eric Mayne, a spokesman for the company’s Auburn Hills, Michigan-based U.S. unit.

“We no longer use this inflator,” Mayne said. “Any questions pertaining to other vehicles are highly speculative, especially considering NHTSA’s inquiry is in progress.”

The latest investigation began with a report regulators received in December about an incident involving a 2002 Chrysler Town and Country minivan. In that case, an ARC inflator was placed in an air-bag module assembled by another parts supplier, Key Safety Systems. Preliminary analysis suggests the gas used to inflate the bag may have been blocked by “an object of indeterminate origin” leading to an explosion, NHTSA said.

Metal shards

The accident led to a lawsuit filed in state court in Ohio. The explosion shot metal through the driver’s neck and into her spine and sent shards into her chest and jaw, according to the lawsuit. The case against Key Safety Systems settled quickly, plaintiffs’ attorney James Lowe, told Bloomberg News in an interview in October.

The complaint says the driver, Lois Dutton, suffered “severe and disabling physical injuries, both physical and mental pain and suffering, was required to be hospitalized continuously for more than three months.” Neither the complaint nor NHTSA’s summary indicates a fatality.

Lowe said Tuesday he hadn’t been aware of NHTSA’s investigation. Chrysler wasn’t named in the lawsuit because the accident occurred during the company’s bankruptcy.

“She got creamed,” Lowe said of Dutton. “It was like an IED explosion.”

The cause of the second incident, reported to NHTSA in June, hasn’t been determined, Trowbridge said. That case involved a 2004 Kia Optima in New Mexico. The air-bag module in that vehicle was supplied by Delphi Automotive Plc, NHTSA said. There was an injury in the accident, according to the agency.

Kia Motors proactively notified NHTSA after learning of its single air-bag inflator incident, company spokesman Scott McKee said in an e-mailed statement.

“Although we are not the subject of the investigation, we are taking this matter very seriously and support NHTSA’s action and will continue working cooperatively with the agency and suppliers throughout the process,” McKee said.
