Basic Problem
By design, the 2016 model year Pilot vehicles have a wide distance between front and rear edge of roof molding.
Vehicles that were produced before September 8, 2015 have molding clips with insufficient strength to maintain/restrain the molding in high cross winds situations or at carwash dryers
