WASHINGTON, DC (December 19, 2019) – Mazda North American Operations has filed a Part 573 defect notification with the National Highway Traffic Safety Administration (NHTSA) for a safety defect, which exists in certain 2019 and 2020 Model Year Mazda3 vehicles. The affected vehicles may unexpectedly stop while driving due to inadvertent activation of the Smart Braking System (SBS) automatic emergency braking system.

Incorrect programming of the SBS control software may cause the vehicle to falsely detect an obstacle in front of the vehicle while driving. In certain cases, the SBS control software may automatically apply the vehicle brakes to prevent or reduce damage from a collision, even though no collision is imminent. If the SBS automatic emergency braking system unexpectedly activates while driving, the risk of a rear-end crash from a following vehicle may increase. There is a warning alarm sound and warning message displayed in the multi-information and active driving displays when this defect occurs.

Approximately 35,390 Mazda3 vehicles are affected in the U.S. and U.S. territories.

No injuries or deaths have been reported from the field to date as a result of this defect.

Mazda North American Operations is headquartered in Irvine, California, and oversees the sales, marketing, parts and customer service support of Mazda vehicles in the United States and Mexico through approximately 620 dealers. Operations in Mexico are managed by Mazda Motor de Mexico in Mexico City.
