After a 20 to 30 mile drive today came home parked up as normal. Came back to car 20 minutes later and it's flashing like Blackpool illuminations. Refuses to start etc. Dashboard errors on rotate. Disconnected the 12v battery and tested it at 11v. Nothing plugged in, no lights left on etc. Called out Mazda technical services who came really quickly. Yip quick battery charge, tested all errors etc. One error shown. Multimedia module drawing on 12v module. Now remember I have had the s/w updates including am035a. The technician reconfigured the module to remove the issue. He reckons it a blip. Really happy with the service but it does make you wonder! Car all fine now🤞 hopefully but be aware the update is not a blanket fix given the technician stated there are 36 modules...
