A BMW drivetrain malfunction poses a significant concern for vehicle owners. The drivetrain, a pivotal system, transmits power from the engine to the wheels, facilitating vehicular movement. The BMW i3 uses a small 12V auxiliary battery alongside its main high-voltage battery.
This 12V battery powers essential electronics, safety systems, and control modules. When it begins to fail, it can trigger a "Drivetrain Malfunction" warning and, in some cases, leave the vehicle inoperable.
