Was about to open the hood to add (for the first time) some windshield wiper fluid. It was then I had noticed a crack from the screw right to the front edge, about an inch long on the bug deflector. Now I had the Mazda dealer install it five weeks ago (at a cost) so I am phoning them to replace the shield. Definitely think the screw or whatnot was too tight, can't think of it being my fault. Any comments?
