The rear glass vista roof panel cracked along the entirety of the glass roof. cracks all along every edge of the glass that don't intersect with each other and ford claims that one area had to be the point of impact. there is no way possible for glass to crack on the opposite end and doesn't intersect with the alleged point of impact for it to have been the cause. i believe the glass is structurally defective and ford will not cover it under the bumper to bumper warranty we purchased for the vehicle. ford gives the service manager the authority to deny the warranty, yet had to give the same service manager guidance on how to test the glass. ford stated i needed to file an insurance claim instead....updated 09/22/15 *bf updated 3/23/2016*js
