Takata's faulty air bags have been linked to yet another injury involving a Honda vehicle, this time in Florida.
In March, a 2003 Honda Civic's air bag exploded and a piece of metal shot out from the bag and dug into the driver's neck, according to Reuters, citing police and hospital records.
About 25 million vehicles equipped with Takata air bags have been called back all over the globe since 2008. Defective air bags made by the parts supplier can spry occupants with metal shards in the event of an accident.
Doctors were successfully able to remove the shrapnel after emergency surgery last month.
"If it is confirmed that this is another rupture, then it would simply reinforce the reasons that we are working so hard to get these air bags remedied as quickly as we can," NHTSA communications director Gordon Trowbridge said to Reuters.
The victim's lawyer said that Honda will be conducting an investigation on Monday and a lawsuit will be officially filed once the investigation is completed.
"Honda is working with representatives of the vehicle's owner to inspect the vehicle and determine whether a rupture of the airbag inflator occurred in this crash. Until this determination has been made, Honda will have no further comment," said Honda spokesman Chris Martin to Reuters.
Six deaths have been linked to the problem so far, according to Honda. Potentially defective inflators can be found in cars made by 10 automakers, like BMW, Ford, General Motors and Nissan.
Last month Honda announced it would add 100,000 vehicles to a recall in the United States over potentially defective air bags made by the Japanese parts supplier that can deploy with too much force.
