Roof Antenna

Hi All,

I recently purchased a brand new 535XI with M package and surprisingly within 7 days I am seeing some sort of crack building up on the edges around the shark fin looking antenna on the roof. Is it normal or a factory defect. I am planning on taking it to the dealership tomorrow. Any thoughts?

Zero idea- terrible. Maybe it got banged in transit?

Best of luck and let us know what they say
