Recall roundup: Mazda6 image

Mazda Motor Corporation is recalling 161,400 Mazda6 sedans in the United States over defective door latches. The problem affects models built before Aug. 24, 2012, for the 2009-2013 model years.

The National Highway Traffic Safety Administration launched an investigation in May 2013 after receiving several reports of the problem. Mazda said that the door latch screws could become loose and cause the side doors to open while the vehicle is in motion.

Mazda said the problem was a result of improper tightening of screws at the factory or uneven door surfaces. Also, no accidents or injuries have been reported. Dealers are instructed to remove the latch screws on all doors, apply a thread-locking adhesive to the door screws and retighten them with the proper amount of torque. Dealers will replace any missing screws free of charge.
