Toyota, Mazda and Suzuki have issued voluntary recalls of more than 18,000 vehicles manufactured between 1996 and 1999, including the popular Toyota Starlets, offering to buy back affected vehicles.
These vehicles are fitted with potentially deadly Takata NADI 5-AT airbags.
"These airbags could injure or kill people in the car by misdeploying in an accident and propelling parts or metal fragments into the cabin of the vehicle at high speed," ACCC Acting Chair Stephen Ridgeway said.
"The airbags have also, in some instances, not fully inflated in a crash, thereby failing to protect drivers as expected."
Owners of affected Toyota, Mazda and Suzuki vehicles are advised to stop driving their vehicles immediately and contact their manufacturer to arrange an urgent, free inspection.
