Air Conditioner problems of the 2018 Ford Edge

On July 12, 2019 I was driving my 2018 Ford Edge that I purchased on September 3, 2018, 75 mph on the interstate and my panoramic sunroof exploded. There were three adults in the car and fortunately, no one was injured, but were showered with pieces and shards of glass, especially the passenger in the back seat. Through conversations while recalling the incident amongst the three of us, there was a loud pop and then it shattered. To our best knowledge, nothing hit the sunroof. I had to have my vehicle towed as there was so much glass that it was not safe to drive. The first dealership told me that due to scratch on sunroof and the air conditioner being on, this caused cabin pressure and ultimately the explosion of the sunroof. We did have it towed to our dealership and they say something hit it to make it shatter. Both dealerships told me that it is not covered under my warranty so I did turn it in to my insurance. I find it ironic that they had differing conclusions. Needless to say, this has been an unfortunate learning lesson. As of now, I do not have my vehicle back, 16 days later. I have expressed my disappointment with my dealership and will also file a complaint with Ford, but know nothing will happen. I appreciate that I am able to file this complaint and hope that any others that this happens to will do their research and know that in order for a change, a report to you needs to happen.
