Some customers may experience the MAZDA CONNECT rebooting or the screen turning black under any temperature. When the concern occurs, MAZDA CONNECT reboots repeatedly, and if the SD card is removed during this reboot cycle, the rebooting cycle ends. This is caused by some SD cards for the MAZDA CONNECT navigation system being manufactured with improper hardware, resulting in a data reading error. To correct the concern, the SD card hardware has been changed.
04-002-21-38092021-06-29. Service bulletin. SERVICE BRAKES. Some vehicles equipped with electric parking brake (EPB) may exhibit a grinding noise from the rear brakes when braking. This may be caused by the rear brake pads not having the capability to remove the rust from the rear brake discs. The red rust accumulated on the discs is exposed to high temperatures during braking, and consequently the rust turns black. As the black rust is too hard to be removed by the brake pads, the rust progress is accelerated, resulting in the grinding noise.
