It’s been 10 years since the National Highway Traffic Safety Administration issued its first recall of airbags manufactured by the Takata Corporation.

But that doesn’t mean they’re all gone.

According to data from CARFAX, more than 6.4 million vehicles equipped with those potentially deadly airbags are still on the road. And according to CARFAX’s vehicle history data, about 40% of them — more than 2.5 million — are located in states designated by NHTSA as “Zone A,” which the agency says “pose the highest threat to safety” due to high heat and humidity.

Zone A includes Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina and Texas.

“Even after a decade of a dedicated and committed effort by vehicle manufacturers, government, nonprofits and businesses, it’s concerning that so many affected vehicles continue to be driven on U.S. roads with these potentially dangerous airbags sitting inside,” CARFAX general manager for data Faisal Hasan said in a news release.

“It’s easy to see recall fatigue settle in for many consumers, but they need to act. We know that raising the alarm with local media can make that happen urgently. Getting an airbag replaced is quick, free to them and could save the life of a loved one — or their own.”

The airbags have a faulty inflator mechanism that can explode on impact rather than inflating the airbag, shooting shards of metal into the passenger cabin, which can injure or kill occupants. The chemical used to activate the inflator becomes more volatile over time when exposed to moisture and high temperatures.

NHTSA said 27 deaths and some 400 injuries have been attributed to the airbags in the U.S. More than 67 million airbags in more than 40 million vehicles from 19 manufacturers have been recalled.

CARFAX said 14 states have 150,000 or more vehicles with unrepaired Takata airbags, led by Texas with 788,000 and California with 739,000. The others are Florida (305,000), North Carolina (216,000), Ohio (209,000), New York (206,000), Pennsylvania (204,000), Tennessee (202,000), Arizona (201,000), Georgia (195,000), Illinois (167,000), Michigan (164,000), Indiana (154,000) and Alabama (151,000).

CARFAX said consumers can track recalls on their vehicle through the free CARFAX Car Care app, or can check for unfixed recalls at no cost using their VIN or license plate information at carfax.com/recall.

The company said it is working with the Alliance for Automotive Innovation to involve more states in the Vehicle Recall Search Service, a free service currently in use in Arizona, California, Connecticut, Maryland, New York, Ohio and Texas to alert residents about open safety recalls and get them fixed.
