No, unless you do something to make it fall off. The paddles will come apart for the following reasons:1.You intentionally pull or pry the external paddle up or at an angle.2. You bump the inside paddle into hard objects like the inside window pillars (frame or molding); mirror mount pedestals or other objects. NEVER ALLOW THE EXTERNAL PADDLE TO GO INTO THE BLACK GLASS BORDER REGION of you exterior windshield. This border area is where the pillars, dash, mirror mount and ceiling are on the inside. 3. You make sudden quick jerking movements (moving fast is ok, but you must smoothly push and pull the paddles across your windshield.Otherwise, the paddles should stay attached until you purposely remove them. The WindshieldWOW! is flexible so that it can contour to windshield glass without falling off and still maintain good cleaning pressure.
