Mazda TSB #16-004-22a
2021 Mazda CX-30
Affected Component: ELECTRICAL SYSTEM
- Summary
- Some customers may complain that Mazda Connect does not start (blank screen) or that it takes a long time to restart/ reboot after starting the vehicle. This is caused by the initialization process with the CMU failing at startup due to a defective circuit board element. To eliminate this concern, the internal hardware (DRAM) of the CMU has been improved.
