Hundreds of Northern Territory motorists have failed to respond to a recall for faulty Takata airbags, police say.
Detective Senior Sergeant Michael Ordelman says car owners should check their vehicles in the interests of their own safety.
"According to one manufacturer there are 459 vehicles in the Northern Territory yet to replace their airbags," he said on Thursday.
"Honda Australia said the majority of these vehicles are in the top end where heat and humidity are known contributors to these airbags failing."
Sixteen vehicle manufacturers, including Honda, Mazda and Toyota, are involved in the compulsory recall.
Some of the airbags may fail to deploy while others may deploy with too much explosive force, potentially rupturing the housing, allowing sharp metal fragments to shoot out.
"If you knew the airbag, a few centimetres from your head, had the capability to kill or permanently injure you I don't believe you would voluntarily continue to drive that vehicle," Sgt Ordelman said.
"In the incident involving a faulty airbag in Darwin in April 2017, the crash that set the airbag off was very minor. The injuries were not."
Police said the process to replace the airbags took just a few hours and was free.
