Transport Canada recalls
02- Brakes#2020264
4,195 units affected
Issue: On certain vehicles, the front brake caliper mounting bolts may not be properly tightened. This could cause the bolts to loosen, which may result in reduced brake effectiveness. If the bolts fall out, the caliper could also come in contact with the wheel rim and cause a loss of vehicle control. Safety Risk: Reduced brake effectiveness could cause an increase in stopping distance and create the risk of a crash. A loss of vehicle control could increase the risk of a crash. Corrective Actions: Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to check the tightening torque of the front brake caliper mounting bolts. If a bolt is missing, the caliper and remaining bolt will be replaced.
- Brakes#2019649
15,746 units affected
Issue: On certain cars, the automatic emergency braking system (called Smart Brake Support or SBS) may falsely detect an obstacle in front of the car while driving. As a result, the brakes may apply automatically when there is no risk of a crash. Safety Risk: If the SBS system activates the brakes unexpectedly when there is no risk of a crash, there could be an increased risk of a rear-end crash. Corrective Actions: Mazda will notify owners by mail and instruct you to take your car to a dealer to update the SBS control software. On certain cars with earlier build dates, the instrument cluster will also be reprogrammed or replaced. Mazda will provide these owners with an updated owner's manual that provides revised information about how to temporarily deactivate the SBS system.
