BMW M6 Gran Coupe third brake light may fall off medium
On certain 2014-2019 BMW M6 Gran Coupe cars, the third brake light — the extra brake light mounted high up, separate from the two taillights — may work loose. If it loosens enough, it can come off the car entirely. Once it is gone, drivers behind you lose one of the lights that warns them you are braking. The piece can also land on the road and become an obstacle for other drivers.
