Mazda CX-30

Issue: 
On certain vehicles, if the ignition switch is left in the "ON" position for too long, it could drain the battery. As a result, when the battery is recharged, and the vehicle is restarted, the airbag warning light will turn on and the airbags won't work in a crash. 

Safety Risk: 
Airbags that don't work properly could increase the risk of injury in a crash. 

Corrective Actions: 
Mazda will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, as necessary, update the vehicle software or replace the airbag sensor unit.

Issue: 
On certain vehicles, damage inside the antilock brake system (ABS) hydraulic control unit (HCU) could cause an increase in brake pedal travel and reduced braking. 

Safety Risk: 
Reduced braking can cause extended stopping distances and increase the risk of a crash. 

Corrective Actions: 
Mazda will notify owners by mail and advise you to take your vehicle to a dealership to inspect the brake ABS HCU, and replace it if necessary.

Issue: 
On certain vehicles, the valve stem for the tires may have been damaged during assembly. As a result, the tires could slowly or suddenly lose air pressure while driving. 

Safety Risk: 
A loss of tire pressure could cause a loss of control and 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 replace all four tire valves with new parts.

Issue: 
On certain vehicles, the power liftgate may partially lower from the fully open position when the vehicle is parked facing uphill on a slope. The liftgate will not lower all the way to the closed position. 

Safety risk: 
A liftgate that partially lowers suddenly could create a risk of injury. 

Corrective action: 
Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to update the power liftgate software. The dealer will also inspect the liftgate drive units and replace them, if necessary.

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.
