Warranty can’t really do anything because there is no problem. If you really want to, get some soapy water and spray it around the shark fin. Close all your doors and windows and put your fan on max speed. Open and close a door very hard to overpressure the cabin. If there is a leak you should be able to see bubbling around the shark fin where air is leaking out.
