I had a crack in the windshield and when they replaced it the technician said it was so rusted from the inside that if anything happened again they would not replace it he had to really do some work arounds he said to even replace this one. That makes me feel that this is a real safety issue if we were to get in a serious accident. There is no rust on the outside around the windshield at all. So I was very surprised when the technician told me that.
