I think it might be the heat or the scratches or the nickel sulfide. It might be all of these things in one way or another but most likely it has something to do with installation tolerances ... however they are attached and installed they are likely not allowing for adequate expansion/contraction at the connection points. Faulty gaskets, or installation errors ... I bet it ties into something like that, which could easily provide a stresspoint that could be further complicated by any of the other potential "causes."

"The couple believes it’s time for the federal government to get involved."
Really? The government? Shouldn't the private sector and local churches take care of this?

" Also, more and more glass is being manufactured in places such as China and Mexico. While it meets standards, it's thinner and lighter."
It's not the heat, it's the poor quality glass. I've had sunroofs for 20 years. I always close the visor on hot days to cut down on the temp inside the car. I'm sure temperature plays a part, but that's only because the thin, cheap glass can't handle it. Sad that the price of everything rises while the quality diminishes and we encourage the behavior by continuing to send jobs to countries that care nothing about our safety.

Nickel sulfide - look it up and tempered glass.

Apparently you have never been in a car when tempered glass shatters. It does sound like a gunshot. I was driving in Charlotte on I-77 in my Jeep when all of a sudden out of nowhere the driver's side glass shattered. Sounded just like a gunshot. I literally pulled the car over and searched for a bullet or exit hole on the other side of my car. Then it dawned on me that I had an accident of that side of the car earlier and tempered glass is bad about creating microscoping stress fractures that can expand overtime and lead to the window shattering without warning. IKEA had this problem with tempered glass table tops getting small scratches in them and then one day just shattering all of a sudden. That's what tempered glass does.
These sunroofs could develop small scratches from road debris (dirt, gravel, sand) and overtime they grow until the stress is relieved off the glass and it shatters.

Sunroofs - love 'em and hate 'em. If they don't explode they eventually leak or fail to operate. Mind you that doesn't keep me from having one in my car.
General Motors offered sunroofs on a few Oldsmobiles, Buicks, and Cadillacs as long ago as the 1930s but then stopped making them for years. Those old cars with sunroofs are very rare now. Apparently they couldn't surmount the problems and maybe some car makers still can't.
