Nearly 20 per cent of Takata airbag recalls in Canada have been completed, up from 15 per cent in June, Transport Canada reports.
Parts availability is slowing progress of the recall, which affects some 4.3 million vehicles in Canada and is the largest in automotive history.
Replacement airbags are being directed first to high-risk areas in the southern United States, where high heat and humidity are thought to cause the devices to detonate with too much force and send metal shards through the cabin.
As many as 14 deaths worldwide have been linked to the defect, but the federal transport agency says there have been no reports of abnormal Takata deployments in Canada.
However, an airbag from another manufacturer, ARC Automotive, is the focus of an investigation into a collision in Newfoundland in July that killed the 83-year-old driver of a 2009 Hyundai Elantra.
The agency says that investigation is “still in the early stages.”
