States U.S. News & World Report:
In a defect notice filed with the National Highway Traffic Safety Administration, Mazda explains, "On certain Mazda6 vehicles, due to inconsistent dimension combination between the outer door handles and its brackets, the outer door handles may stick which may prevent the door from latching. This situation may allow the door to open while the vehicle is in motion."
Approximately 30,000 could be affected by the defect. Mazda started issuing the recall a couple of weeks ago. So far no accidents or injuries have been reported due to the issue.
