My 2018 Ford F-150 with 7,800 miles was parked in my drive way while working in my garage at my home. The windows were rolled down about 3" to keep the heat from building inside the vehicle. It was 84 degrees outside temperature. When I was rolling up my windows to put the truck back in my garage, the drivers side window closed and I heard a cracking sound. No visible crack was evident. I rolled the window up a second time and a very small crack appeared in the upper corner where the glass turns upward next to the rear view mirror. The truck was taken to my local dealer and they took pictures and turned into Ford. It was refused as they stated their was impact. My truck has factory window guards and there is not a mark on the passenger side guard or paint. I sent a claim to Ford and they still claim it was impact. Well Ford all I have to say as where the crack began to propagate their is no way possible from the interior or exterior of the vehicle that you could humanly possible impact this area of the window as it is completely concealed. This vehicle was stationary in my concrete driveway while rolling up the windows. There is also no way possible that any foreign matter could have got in the window track. The first photo is from the exterior and the second is from the interior showing that the window broke from the most protected area and directly off the corner of the glass where it initially started.
