On Saturday, April 15, 2023 at approximately 1pm, I was driving my 2017 Jeep Grand Cherokee Summit on Texas Hwy 16. The weather was clear and traffic was light. There was not a vehicle, within 200 feet, in front of mine. The glass sun roof / panorama roof was closed. I heard a loud bang as if something had struck the roof of my Jeep. I then heard glass cracking and wind noise. I did not see anything strike my Jeep or bounce off of my Jeep. I did not see anything lying in the roadway behind my vehicle. I stopped my Jeep and saw the stationary portion of the glass panorama roof was shattered. The movable glass sun roof was not damaged. I did not see any marks or damage to the painted metal roof or metal trim around the glass panel. The worst of the damage appeared to be located at the front corners of the panel, nearest the front of the vehicle. There was not a visible area of impact. I am currently trying to locate a repair shop to replace the glass. I have not made an insurance claim. I do not believe the glass was damaged by an object. It appears the glass shattered due to stress on the glass, possibly caused by an incorrect installation by the manufacturer or defective safety glass. My Jeep has not been involved in a collision, nor have I altered any portion of the vehicle. I believe that had the glass completely shattered and dropped into the passenger compartment of my Jeep, I, and other occupants of my vehicle, would have been exposed to flying glass particles.

The Dashboard of the car is rising and waving due to the heat of the Sun in Louisiana. This is reflecting a shean of direct/indirect sunlight off the wrinkles into the drivers eyes. It super distracting, a safety concern and a fault in the Adhesion used in the manufacturing process! HELP!! It needs to be fixed at the manufacturers level!!

Side driver's and passenger windows shattering - walked to car parked outside. Opened driver door, sat down and closed the door. Upon impact of closing the door the entire passenger side window shattered inside the car. I have read online that this has happened to other Grand Cherokee drivers.

Brand new Jeep Grand Cherokee with less than 500 miles, on a clear day while driving approximately 50 miles per hour, the front portion of panoramic sunroof spontaneously shattered. Sounded like a gunshot. To add insult to injury, car manufacturer claims they are not liable under warranty because I cannot prove the glass and/or design were defective. The manufacturers need to stop making panoramic roofs or else cover them under the warranty.
