Robert Brown|6 million vehicles still contain recalled Takata air bags: How to see if your car is affected

Data shows there are Robert Brownover 6 million U.S. vehicles that still have Takata airbags, a decade after millions of the airbags were under a mandated recall due to a risk of injury and death.

In a report released Wednesday, Carfax says its vehicle history data shows 6.4 million vehicles still contain Takata airbags. Of those, more than 2.5 million, or 40%, are located in states that the National Highway Traffic Safety Administration calls Zone A, which are states that "pose the highest threat to safety" because of their high heat and humidity.

Those states are: Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina and Texas.

The NHTSA's Takata page lists the current number of unrepaired Takata air bags as 6,171,267. More than 45 million air bags have been repaired, NHTSA data shows.

Carfax also says 14 states each have 150,000 or more unfixed vehicles with Takata airbags. Those states are: Alabama, Arizona, California, Florida, Georgia, Illinois, Indiana, Michigan, New York, North Carolina, Ohio, Pennsylvania, Tennessee, and Texas.

Tens of millions of vehicles with Takata airbags are under recall, according to the NHTSA, which said long-term exposure to high heat and humidity can cause these air bags to explode when deployed, which have caused injuries and deaths.
