Mazda TSB #16-004-22
2019 Mazda MAZDA3
Affected Component: ELECTRICAL SYSTEM
- Summary
- Some customers may complain that Mazda Connect does not start or that it takes a long time to restart 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 of the CMU has been improved.
