A friend of ours recently purchased a 2012 Jeep Grand Cherokee. Today she showed my wife how the roof of the Jeep has virtually exploded outward and also inward. In other words, it's gone completely out of shape. It did it all at once with a loud bang. Have you ever heard of this before? Just trying to help a friend.
Exploding sunroofs are not unknown, they can occur on any vehicle, but the cause is difficult to determine. She could have an automotive glass company take a look at it to see if they can spot anything amiss with it.
