KNOXVILLE (WATE) – The National Highway Traffic Safety Administration is looking into parts made by a Knoxville airbag company.

The investigation comes after two incidents where airbags ruptured, in 2009 and 2014.

Both vehicles involved had inflators made by ARC Automotive.

The first was a 202 Chrystler Town and Country minivan, the second was a 2004 Kia Optima.

The root of the cause of the Kia rupture, is unknown at this time. The Crystler rupture is thought to be caused by and object blocking the exhaust path of the inflator, putting too much pressure into the airbag.

ARC released the following statement about the investigation:
