Anybody ever have this happen when closing their door?
Brand new 2015, 99 miles, leaving for our first Day-Trip. Guess Not.
Also....... Replacement by : Airstream, Mercedes or Safelite?

New one on me!
Replacement by Airstream; those are not factory Sprinter rear windows, they're by CR Laurence, same as your tinted side windows.
On edit— interesting to see that the rear doors don't appear to be insulated; all I see is void spaces behind the plastic interior molding.

Wow! Did the glass shatter or simply fall out? (Then shatter)

Holy Blowout Batman!
Sorry this had to ruin your first trip. Hope you get it fixed quickly.
I'll make sure to take it easy when I close mine.

Be interesting to see if Airstream foots the bill for this. Normally glass breakage is not covered by the warranty. Good luck!

Rear Window Blowout
Those rear door windows are installed by Mercedes in the factory they are not an Airstream add-on. I recommend you go to a Mercedes Sprinter dealer for warranty replacement. You can also check with the Airstream dealer you bought it from to be sure. Mercedes may claim the window surround installed by Airstream caused the window to break - a possibility.

If these are stock Mercedes windows then the only place you'll be able to get it fixed is at a Mercedes dealer.

From the picture, it appears that there was an adhesive failure unless the OP removed the glass after it broke.

They aren't. Discovered that when I was eliminating the plastic/metal interface squeaking. There's not a lot of room to put insulation but I stuffed what I could in the voids. I suppose if one wanted to drill holes in the stiffeners, you could shoot Great Stuff in those voids.

I love the German engineering, takes me back to the AIR TIGHT VW that I had to crack a window to shut the door without slamming the door several times. Mercedes needs to have a one-way pressure valve for the Sprinter. (Protagonist, please tell me the proper name for that valve---I really appreciate your knowledge.)

As far as removal, I only removed the loose glass around the edges after shatter, 95% of what is gone was gone on the blow out.
All that is left is the minuscule amount that is actually "adhesived" on. I did not attempt to actually clean the frame.
Now I have 2 differing theories on where to proceed. Is it Sprinter or CR Laurence(Airstream)?
Not that it matters on a holiday weekend, I am certain not to get a call back until Tuesday.

Did the window shatter when it hit the ground? Hope no one was hurt. In answer to Mordux's question, I believe Mercedes is the proper place to go.

Shattered on Close. Safety Glass type shatter, millions of pieces flying.

Check Valve maybe?

Not true. Any good auto glass shop could replace that window. But this is a new van still under warranty. However I'm not sure glass is covered by warranty. Worth checking.

Pressure relief valve. Check valves block reverse flow; they don't necessarily relieve pressure.
Airstream Interstates already have one, though. Watch the small openable window on the sliding side door when you close it with the roof vents and all windows closed. The side window "burps" slightly as the excess pressure escapes. On my van, the only times I ever completely close my MaxxFan vent are in the winter when heat from my furnace would escape out the vent, and when I'm expecting a howling thunderstorm or mild hurricane while the van is parked at home. The rest of the time I leave it at least partially open because it's very rain-resistant unless it's raining sideways, and it helps the van from overheating— and provides pressure relief.
I don't think that's the cause. Tempered glass has a unique property; it doesn't crack, it only shatters. But there can also be a delayed reaction. An impact that would normally crack non-tempered glass causes stress to build up in the tempered glass but doesn't break it. That stress can continue to build over time until the glass finally shatters, possibly long after the impact that started the process. In this case, it wasn't necessarily slamming the door that broke the glass, it might have been some other impact beforehand that started it, and the door closing only finished the job. The original cause could have been a small rock thrown up by a lawn mower, a hailstone, or some other impact that you didn't even notice at the time.

How does a pressure relief valve work?

The simplest form is a valve held closed by spring pressure; a calibrated spring that requires a known amount of force to compress. When pressure against the valve exceeds the pressure of the spring, the valve opens, and when the pressure drops, the spring forces the valve closed again.

So basically a spring-loaded check valve then?

Whoa! What a way to start the summer. Sorry sorry to hear about your issue. Please let us know of the outcome.
Recently insulated the space between the glass and the airstream panel with reflectex. Here are some close up pix. Looks like the window may be Mercedes. The edge is finished and looks to be factory painted.
