Mazda will recall approximately 100,000 midsize vehicles in the U.S. in order to fix an issue with the tire pressure monitoring system.

The recall affected model year 2014 and 2015 Mazda6 vehicles, according to the Associated Press.

 The automaker said in documents posted on Tuesday by U.S. safety regulators that if the air pressure drops on all four tires at the same time the monitoring system might not warn drivers of the issue.

"If the pressures of four of the tires on an affected vehicle gradually drop at the same time, the tire pressure monitoring system may not warn the driver of the drop in tire pressure," said the National Highway Traffic Safety Administration in its recall summary. "A vehicle that is driven with under-inflated tires may experience a sudden tire failure, increasing the risk of a crash."

Low air pressure can cause a sudden tire failure, increasing the chance of a crash. Under federal regulations, the tire pressure monitoring system must alert the driver if one or more tires lose 25 percent of the recommended air pressure by illuminating a warning light in the instrument cluster. 

Mazda said that the issue hasn't caused any injuries or crashes yet. The recall only affects vehicles in the U.S. and its territories.

Tire pressure monitoring systems have only been required on vehicles in the United States since the 2008 model year. The rule was part of the Transportation Recall Enhancement Accountability and Documentation Act of 2000.

Regulators said that when drivers failed to check tire pressure, it increases the chance of a number of types of crashes, according to The New York Times.

Dealers are being instructed to update the tire pressure monitoring software, free of charge.

All owners should expect a letter regarding the recall in the mail within the next few weeks.

The recall is expected to begin on Dec. 5, according to the AP report.
