The failure of Volkswagen's automatic start-stop system is such a thing.

Most automatic start-stop faults are established when the control unit detects that the vehicle can't start normally when it is turned off. There are many reasons, such as insufficient battery power (high battery requirements for automatic start-stop vehicles). The throttle is out of order

There are also some situations, such as turning on the air conditioner, electric heating and sound, which will also make the start-stop function invalid.
