Mazda Motor Corporation has decided that a defect which relates to motor vehicle safety exists in certain 2022-2023MY CX-30 vehicles and 2023MY CX-50 vehicles. If you received this notice, your vehicle is included in this Safety Recall. What is the problem? The Anti-lock Braking System Hydraulic Control Unit (“ABS HCU”) may be damaged which can increase brake pedal travel length and reduce braking ability, which can increase the risk of a crash. What will Mazda do? Protect What Is Important To You For subject CX-30 vehicles, your Mazda dealer will check the serial number of the ABS HCU of your vehicle and if it has an affected serial number, the part will be replaced with a new one. For subject CX-50 vehicles, your Mazda dealer will replace the ABS HCU with a new one as it has been already verified to be an affected unit. The repair will be performed free of charge and at no cost to you. How long will it take? It will take approximately half an hour to complete the inspection, and if replacement of the ABS HCU is necessary, it will take approximately two hours to complete the repair; however, your Mazda dealer may need your vehicle for a longer period of time. Mazda will provide alternate transportation, if needed, when your vehicle is at an authorized Mazda dealership for a recall repair. Please schedule an appointment with an authorized Mazda dealer so they can discuss and accommodate your needs. What should you do? Mazda is concerned about your safety, and we encourage you to contact any authorized Mazda dealer to schedule an appointment to have your Mazda vehicle inspected/repaired as soon as possible.
