2019 Mazda Mazda3 Recall

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.

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.

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.

On certain cars, the interior rearview mirror glass was not properly attached and could fall off.

If interior rearview mirror glass suddenly falls off, the driver’s rear visibility will be decreased. This could increase the risk of a crash.

Mazda will notify owners by mail and instruct them to take their car to a dealer to replace the interior rearview mirror.

The material on the driver and front passenger seatbacks may not be installed correctly. This could cause it to in interfere with the release button for the head restraint. As a result, the button could be stuck in the ‘release’ position and allow the head restraint to move up and down freely. In a crash, this could allow the head restraint to detach.

A head restraint that does not remain in place in a crash could create a risk of injury.

Mazda will notify owners by mail and instruct them to take their vehicle to a dealership to install a plastic spacer at the bottom of the head restraint lock release button.

On certain vehicles, a software error in the Powertrain Control Module (PCM) could cause the valve clearance adjuster not to work properly. This could result in internal engine damage. If this happens, the engine may misfire and lose power. In the worst case, the engine may stall while driving without the ability to restart it. The malfunction indicator light (MIL) may also turn on in the instrument cluster.

A sudden loss of engine power could increase the risk of a crash.

Mazda will notify owners by mail and instruct them to take their vehicle to a dealer to update the PCM software.

On certain cars, the wheel lug nuts may not be properly tightened due to a manufacturing issue. This could cause the nuts to loosen or fall off, and could result in a wheel separating from the car.

A wheel separation could increase the risk of a crash. A wheel that separates could also hit another person or vehicle.

The company will notify owners by mail and instruct them to take their car to a dealer to re-tighten the front and rear wheel nuts to the proper specification.

On certain cars, the passenger airbag status and seat belt status indicator lights may not work properly. These lights are designed to indicate when the passenger airbag is turned off and when a passenger is not buckled. Instead, this problem could cause the passenger airbag status indicator light to incorrectly turn off when the passenger airbag is deactivated. It could also cause the passenger seat belt status indicator to incorrectly turn off when the seat belt is not buckled. Additionally, the rear seat belt status indicators may turn off regardless of seat belt use. Note: This problem has no effect on the operation of the airbag system.

Seat belt and airbag indicator lights that do not work properly could cause confusion. They could also cause a driver to be unaware that the rear seat occupants are not buckled. This could increase the risk of injury in a crash.

The company will notify owners by mail and instruct them to take their car to a dealer to replace the seat belt indicator assembly.
