I just wanted to Add my comment here at the Start of this TSB Compilation for the Mazda CX-60.
If your Mazda and or its Production Date is within any TSB listed here in thread does not necessarily mean your car will be defective or have any future problem.
TSBs are to inform Dealers on a potential issue if it occurs and what "a" fix or repair method is.
Majority of owners never see some of these issues.
TSBs are NOT A RECALL to repair, Recalls are always Safety Related and car owners usually receive a registered letter in Mail from Mazda Distribution in your country telling you what to do to address Recall issue.
Please if you have any issues discuss with Dealer Service Dept FIRST. Then if no satisfaction quote a TSB number you have found, again remember each Mazda Continent has a different numbering system and Date for their TSBs.
Obviously below is for CX-60 in EU/UK/AU/NZ sold markets.

ELECTRICAL CONCERN AND OR MULTIPLE DTC's DUE TO AFTERMARKET DEVICE(s)
Aftermarket Accessories or non Mazda Device may be
the cause of an electrical concern either a DTC or IC Warning or car feature not working.
Below are a few examples of unusual electrical concerns caused by aftermarket devices.
Examples:
1. Devices connected to the DLC-2 (battery discharge/DTC stored).
2. Devices plugged into the 12V outlet socket or High Power plug outlets.
3. GPS tracking device (engine no start or battery discharge).
4. Dash Camera (DTC stored).
5. Non-certified USB Cables for Apple Carplay™/ Android Auto™ will not connect.
6. Over-sized wheels/tires with incorrect GPS location and or Vehicle Road Speed.
7. Decorative trim and/or cover on the START/STOP ENGINE Button malfunction.
If you experience an issue try removing your Accessory Device and see if issue is resolved.
