Got out to my car today and found a crack about two inches long in driver side windw. There seems to be no impact on either side of the window. You can feel the crack on the inside and not the outside. Took it to the dealer and he called it a scratch. He took pictures and sent them into ford. Hopefully there will be a good response. How can it be determined to be a scratch and not a crack? If it is a crack could it be the extreme cold here in NY? Anyone else have this kind of problem? Thanks for any info. 2015 ST with 4800 miles.
