Panoramic sunroof spontaneously exploded when driving on highway. No warning. Sounded like a gunshot. Had to pull over on the highway and clean off as much glass as I could so it did not cause injury or damage to other motorists. Looks like many other Tucson owners are experiencing similar issues. Has not been inspected yet as dealerships and insurance are closed today.
