My windshield started to crack from the very bottom middle (just above the hood) and made its way up and splintered in multiple directions rapidly. I believe it’s maybe heat related (probably defective) because I can’t find an impact spot if it was a rock or something similar. I can feel the crack on the outside of the windshield at the very bottom (just above the hood) where the glass starts for about 3 maybe 4 inches, a nice little groove then after splintering in multiple directions I can no longer feel the cracks. Can you please look into this issue.
