windshield again

Well 2nd year in row on Christmas that I had windshield issues. Last year it developed a crack along the bottom edge and no rock chip was found. Safelite epoxied it and thought it was a stress crack. Well Christmas Day I was turning onto a road and hit a bump while I was turning and we hear a noise. Thinking it was the sound people here talk about with the suspension noise I didn't think much of it, Well a few minutes later my wife says is that a crack in the windshield and sure enough a double wide one right down the middle. Went we got to where I could look it starts at the very top above the camera and snakes down, 2 parallel cracks about 1/2" apart. Again when I run a razor blade over it you can't feel a crack on either the inside or outside. Definitely stress related, so a new one is on order. Oh well. Happy New Year to all....
