Mazda Recalls Cars to Fix Tire Pressure Monitors Mazda is recalling nearly 100,000 midsize cars in the U.S. to fix a problem with the tire pressure monitoring system. The recall affects certain Mazda6 cars from the 2014 and 2015 model years. The company says in documents posted Tuesday by U.S. safety regulators that if the air pressure drops on all four tires at the same time, the monitoring system may not warn drivers of the problem. Low air pressure can cause a sudden tire failure. Mazda says the problem hasn't caused any crashes or injuries. The recall affects only the U.S. and its territories. Dealers will update the tire pressure monitoring software at no cost to owners. Mazda will notify owners by letter. The recall is expected to start on Dec. 5.
