Navigational (global Positioning System) Gps problems of the 2016 Hyundai Sonata

The shark fin antennae on top of the vehicle was ripped off in a car wash; the antennae serves to transmit radio/gps/data to & from the vehicle which will cease to function if it the cover is removed and components damaged. Hyundai description: the shark fin antenna will receive am, fm broadcast signals and transmit data multiple Hyundai dealers have been contacted for quotes on replacing the antennae which they claim will cost $1500+ since the top of the roof must be removed and electronics/circuit board/cables must be replaced; it appears to be a common issue with these shark fins according to the dealers and online research. The gps and data transfer could be a major safety factor depending on the systems affected. These shark fins need to be replaced with a more resilient system. Owners are unable to 'store' the antennae when taking it to the car wash as it is not removable or retractable. It is a design flaw. I've read that many have lost them simply driving the vehicle --not agitated using a car wash.
