Subject: Mazda Service Program (MSP) 53. 2019 CX-3 & 2018-2019 MX-5 With Direct Tire Pressure Monitoring System (TPMS) Panic Alarm System Activates While Driving. Mazda Motor Corporation has decided to conduct a Mazda Service Program (MSP) on certain 2019 CX-3 vehicles produced from February 27, 2018 through October 12, 2018 and 2018-2019 MX-5 vehicles produced from October 3, 2017 through October 15, 2018. On certain subject vehicles equipped with Direct TPMS (TPMS wheel sensor is directly mounted on each wheel), it is possible that the panic alarm system may activate while driving, and the horn may sound intermittently, and hazard warning lights may flash. The panic alarm concern will stop after cycling the ignition switch off, then on again. No DTCs are stored. Action Required: Beginning today, reprogram the body control module (BCM) to the latest calibration using MMDS for all affected CX-3 and MX-5 vehicles in dealer inventory, and when customers bring their vehicles for maintenance, or other service/warranty work. The subject vehicles must not be delivered to customers until the repair of MSP53 is completed. Please inform the customer that the BCM will be reprogrammed to the latest calibration, free of charge. If a vehicle is sold with an open MSP53 your Step 3 PDI warranty claim will be subject to debit.
