It happens. More frequently than your imagine. It should be covered under your bumper to bumper warranty.

Wow, that is impressive! Sorry that happened to your TH. Good luck getting it resolved with FCA. I was also thinking the bumper to bumper should cover it. Keep us posted.

Maybe you found another hidden Cherokee Easter egg??

 

[Hudsonhawk]

You are not the first person to have this happen. There have been a couple of others on the forum who reported the same thing.

 

[rumrunner]

took my jeep to the dealership and they also could not explain why the window totally fell a part.

comforting, thanks for sharing

 

[taatmk]

Weird!

Just want to share a similar experience from a few days ago. Returned from work, parked in the driveway, shortly after saw the shattered tailgate glass. No evidence of an object hitting the glass. Dealer and Customer Rep said that the glass is not covered by warranty, say so in the manual!

That looks very similar to the OP. I would still argue that it's not external damage, but design/defect with how the glass is mounted or imperfection in the glass.

 

[Cherokee_Limited_2015]

Chrysler's response is that there is no defect, and that glasses get shattered for many other reasons that's why its stated in the manual that the glass is not covered.

It depends on how persuasive you are.

I had spontaneous failure of my driver door glass on a Ram 2500 replaced under warranty.

 

[rumrunner]

sounds like another class action law suit is in order. wonder how you start one of those?

can it be covered by your auto insurance? I've only had from windshield replaced over the years

These windows are glued in with polyurethane, a flexible and permanent bond, there are no mounts, only alignment pins. There is no frame to get jammed up with.

Fitment of the glass in the hole cannot break it after the fact with tempered glass, it will break right away.

A defective piece of glass will usually break very shortly after installation and before you would even have purchased it.

Flex is not an issue as I can take your door glass lie it on the floor and stand on it with it flexing toward the ground without it breaking.
You usually cannot detect where the initial impact of a tempered piece of glass was as it violently fractures due to the potential energies stored inside of it being turned kinetic. You will not find anything inside the car as if it had enough inertia to go through the glass (a bullet) it would have kept going through something else.
You might be suprised how many things there are out there than can break a window, but thermal shock is not one of them unless you are using boiling water on a frozen window or liquid nitrogen on a window in Phoenix AZ in a Walmart parking lot on a 100 degree day...

The most common things for glass breakage are stones. The stones can be flicked from a lawn mower, weed whacker, passing car, or even dropped from a bird who thought it was a shell. They will always deflect after impact and you will never find them in the car.

Glass can get chipped and not break right away, even tempered glass, but when it does break, it is because of the chip.

All this to say, possibly a few windows have gone bad, as they do on any car from any brand, but most, if not all, of your glass breakage problems were caused by external forces (bb's, rocks, etc.), and are subject to coverage by your insurance company, not the warranty.

I do auto glass for a living and have yet to have had someone show me evidence that any of what I have said is wrong...

I filed a complaint with U.S. DOT National Highway Traffic Safety Administration waiting for a response. I figure if that if there are many cases of spontaneous glass breakage, then Manufacturer has to accountable.
Insurance covers minus the deductible.

Explain the, at least three, photographic examples of the "same" failure mode/location on the rear window glass in a static environment.

Missing glass does not mean point of contact. In fact, usually it does not. I could break 15 cherokee back glasses 15 different ways and wind up with some looking the same and others looking very different. It does not matter where the impact occurred as when tempered glass breaks it does so violently and unpredictably. Where the glass falls can be somewhat consistent due to the shape of the window it's self. You have to understand how this type of installation works... there is a bead of glue between the glass and the body the whole way around the window that is the only thing holding the glass in. Once broken, its like an extremely complicated game of dont break the ice... you can even notice it in the picture of the drivers side of the red Cherokee. You can see where a strip of glass is stuck to the glue still and how on both sides of it the glass has fallen. Where the glass fell has absolutely nothing to do with how it broke. It is hard to tell with the quality of images that were posted, however from what I can see on the passenger side, there are a few white spots in the glass that look like small impact points... Again it is very hard to tell without a high quality image or seeing it in person, however I can almost guarantee that it was not due to manufacturer error. To be honest, I hate being on the side of the manufacturer as many manufacturers of different products really do create poor products. Unfortunately I deal with glass every single day and know how it works from experience alone, if not from the training that I have received. What is being implied just simply isn't how glass breaks...

If a bad part is installed, one that is going to break because of poorly made materials, it will do so the first time that its its out in a hot parking lot. Unless you got yours delivered directly from the factory, your vehicle was sitting at the dealership for a while every single day out in the Sun. This would have caused it to break far before you ever received it.

Also, static environments are extremely hard to maintain. I know a girl who lost an eye while standing inside her garage from her neighbors mowing the lawn across the street. I have met someone who had a seagull drop a rock onto their windshield and break it. I personally have looked at a side window that looked fine save for a single tiny white impact point. The window was still in tact and I let the customer know it would most likely be fine, but the next day I received a call from they stating that their window had broken while in the garage with the overhead door closed.

Glass is unpredictable in the way it breaks, but it doesn't just break or our warehouses would find spontaneously broken windows all the time... which they don't.

I hate to say it, but the glass was most likely chipped or broken already and you didn't notice it right away, or it got worse while sitting in the "static" environment... believe it or not, this occurs all the time. Sometimes we can even point out the impact point, which is usually in a different spot than any fallen glass...

Thanks for the detailed response. It's hard to let go of "common sense" understanding of complex subjects. From the point of view of the consumer, however, "It was just sitting there and it broke! It wasn't my or anybody else's fault. Fix it!"

I do completely understand that, and to be honest a lot of how Auto Glass works doesn't make sense with the Hollywood ideas on how it works. It's like trying to kick a windshield out, which is not possible on any vehicle build after 1990

Oh, @Xinarin13, the reason I jumped in earlier on the thread is that my Dodge dealer stated that "spontaneous failure" was rare, but not unknown, and that's why they repaired mine under warranty. Note that the vehicle was less than 24 hours off the lot and had ~3 miles on it when I got it.
