NHTSA Complaint #11716473 — 2023 FORD BRONCO

My vehicle was sitting in a small parking lot at work and the back liftgate glass blew out onto the pavement. It was 95 degrees outside. The liftgate arms and all the shattered glass were on the outside of my vehicle. I called the dealership and was told nothing they could do and they didn't even ask to look at it. I paid out of pocket to replace the glass. Then on January 24th when it was -25 degrees I remote started my vehicle and it ran for about 10 minutes, I went outside to leave for work, got in started my vehicle and looked in the rearview mirror and noticed the leads for the rear defrost were hanging down. I got out of my vehicle to find shattered glass all over my driveway and the liftgate glass arms outside of my vehicle. I called Ford and I called the Ford dealership. No help. Just told they've never heard of this happening. Well, I told them the1st time it happened and this is the second time. Brought to the dealership and no answers. Asked if they reported this and the last incident to ford as it's my understanding they are to notify corporate. Nothing. I asked them to see if there was a short in the rear defrost or any other reason why this is happening. I got a to bad so sad, if ya want it fixed it will be $1700. There are no warnings that this will happen.
