Rear window spontaneously exploded on July 8th around 11:00am. My truck was parked and not driven for two days. The rear window exploded and shattered. The glass was everywhere, In the truck bed and all over the cab. The seats and carpet have shards of glass embedded in them. I called Tom Masano Ford in Shillington PA. Spoke to Lydia a service advisor. She told me that Ford would not cover the repair/replacement of the rear window. She stated that Ford would not take any responsibility for this safety issue. There was no warning lamps, messages, ect prior to the window exploding. We have an appointment at Tom Masano Ford on Monday July 18th.
