Even cars that had the problem fixed may need a second recall, because similar problems have emerged with the replacement airbags.
A 58-year-old man who died in a Sydney vehicle crash last week is suspected to be the 18th person globally - and the first in Australia - to have been killed as a result of the faulty product after police said he was struck by fragments.
All manufacturers caught up in the airbag recalls do not produce inflators themselves, thus, they rely on third party suppliers, like Takata, to provide these parts.
A Sydney man died on July 13 when the Takata-supplied airbag in his Honda ruptured following a two-car crash.
Globally, 18 deaths and 180 injuries have been linked to the airbags.
Australia's consumer watchdog said on Monday it was investigating the recall of Takata Corp (7312.T) vehicle airbags, a day after police said a man's death in a Sydney auto crash could be linked to the faulty safety equipment.

"Do not ignore or delay responding to a letter from your car's manufacturer or retailer asking you to have your car's airbag replaced", Australian Competition and Consumer Commission chairman Rod Sims said.
"We would have very serious concerns if manufacturers were found to be misleading consumers about their car's safety in breach of their obligations under consumer law". Check out this section of NHTSA's website, which is devoted entirely to the largest recall in automotive history.
If auto owners have concerns, they should contact their local dealership or the manufacturer of the vehicle.

Other automakers have 30 days to file their appeals.
Toyota, Mazda, BMW, Lexus, and Subaru have all among the auto brands that have admitted to this issue, and between originally-faulty airbags and defective replacements, there might still be millions of cars with deadly airbags on Australian roads.
Over 100 million vehicles, 70 million the United States alone, fitted with Takata airbags have been recalled since 2004, when reports of an issue first arose. Ford has told the National Transportation Highway Safety Administration (NHTSA) that it will fight the recall, because, the company says, the airbag inflaters it uses have a chemical that it claims has been effective against the too-violent inflater ruptures.
If you've already had your airbag replaced: Contact your vehicle manufacturer to ask what kind of airbag it is and how long it's expected to last.
