Official summary
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.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
