The official record describes a potential crash, fire, injury, or loss-of-control consequence.

“Mazda North American Operations (Mazda) is recalling certain 2019-2020 Mazda3 vehicles. The Smart Brake System (SBS) can falsely detect an obstacle while driving, activating the automatic emergency braking system and suddenly stopping the vehicle. Stopping the vehicle unexpectedly increases the risk of a crash. Mazda will notify owners, and dealers will update the SBS software. In addition, vehicles with certain production dates will receive an instrument cluster software update or replacement and a replacement owner's manual. These repairs will be performed free of charge. The recall began February 14, 2020. Owners may contact Mazda customer service at 1-800-222-5500, Option 4. Mazda's number for this recall is 4219L.”
