We have a 2016 Mazda cx5 diesel car with automatic transmission.

(CX-5 SKYACTIV-D 2.2 (129 KW) 4WD (2015 - 2017).

It produces the following fault, but not always when the car is going 110 km or faster and you have to brake suddenly or firmly. When this happens it randomly throws the "parking brake retracted" , "tire pressure problem" , and "ESP fault" pictogram on the dashboard at the same time. On the right hand side of the information display the message "SCBS mallfunction" appears. In this case the car can go max 130-140 km/h. Automatic transmission does not work, as if it is frozen. If I put it in manual mode, it is not possible to shift up or down either. What helps the problem is that if I stop somewhere, I stop the engine and start it again. Then it starts without a problem and as if nothing happened. Took it to mazda dealership for diagnostics where unfortunately it only shows a general fault. So they didn't know what the problem was. No specific component fault is indicated by the diagnostics. At the service station they did a complete engine cleaning because this type of engine is very dirty. They replaced the pressure sensor again. But the fault came back the same way. Then we took it to a car electrical specialist who said it was an electronic problem. As a test he updated the ECU software to see if that would solve the problem. Unfortunately, after that, the fault came back in the same way. The electronics specialist said he had an idea what the problem might be. But we haven't got to him yet. Has anyone encountered similar or the same problem? And if so, what solved the problem?
