WASHINGTON, DC (CBS13) – The National Highway Traffic Safety Administration is worried about drivers of certain Ford and Mazda trucks.

A high number of MY 2006 Ford Rangers and Mazda B-Series trucks with defective Takata airbags aren’t being repaired. The trucks have do not drive warnings and the airbags must be replaced immediately. Both models also have “Alpha” airbags– meaning they are at a far higher risk of an airbag explosion that could injure or kill those in the vehicle.
