Feb 19, 2020 · EXTERIOR LIGHTING:BRAKE LIGHTS
BMW of North America, LLC (BMW) is recalling certain 2014-2019 M6 Gran Coupe vehicles. The third brake light may become loose, possibly allowing the light to detach from the vehicle.
Consequence: If the third brake light detaches from the vehicle, it would no longer provide the required lighting to following traffic, or it may become a road hazard, increasing the risk of a crash.
Remedy: BMW will notify owners, and dealers will inspect the third brake light and properly secure it with new fasteners. If the third brake light detached from the vehicle and is damaged, it will be replaced. All repairs will be performed free of charge. The recall began April 17, 2020. Owners may contact BMW customer service at 1-800-525-7417.
