What's wrong?
This BMW recall involves the engine starter, the electric motor that turns the engine when you press the start button. Inside that starter is an electrical relay, a switch that sends power to the starter only when the vehicle is being started. That relay has to stay clean and dry so the electrical connection stays controlled.
On affected 2019-2022 vehicles, water can reach the starter relay. Once moisture gets inside, corrosion can build up on the relay contacts. That corrosion changes the electrical path, which can keep the relay from working correctly, make the starter fail to crank the engine, or cause the relay to overheat and short circuit.
There is no warning sign before failure. An owner first notices the problem when the engine does not start, or when the starter area overheats without an earlier dashboard message or symptom.
