Hi All,

Bought a 2022 Jeep Grand Cherokee WL Laredo 13 days ago, had the vehicle for 5-6 days before the rear hatch glass shattered.

No grass was cut, not near a road Where a rock hit it….I am on the road about 80-90 miles a day. Closed the drivers door and I ducked….. broken glass

I love this car, the short time I have had it, but this is a bit confusing and concerning - Chrysler/MOPAR sending the wrong glass 2-3 times is even scarier and the rear glass is now on back order.

The dealer has been amazing to work with as they provided me a used car to drive so I can get to work and back.

Jeep Cares/Customer Service has not been helpful. I will say, I am a bit concerned about quality control/reliability on this thing and FCA.

Any thoughts/suggestions would be greatly appreciated. I was going to join and be a member of the forum prior to all this happening, but this is my first post.

Curious to find out what caused it, tensions in the glass when it was mounted or a simple glass defect, or something to do with the body flex of the WL? Probably an isolated case I would think...

On another site for the WL's (facebook) someone had their panoramic sunroof shatter out. Wonder if it's body flex? I remember reading a year or two ago that the new platform for the GC's was going to be an existing Alfa Romeo chassis? True or not, I don't know. Makes sense if you want to save money...

Yeah I don’t know what to think. With the car having 500 miles on it and in it for 5 days, I am very skeptical.

I requested an extended warranty and FCA/Jeep Customer Care declined my request. To me, that shows right there they do not trust in their product and stand behind their vehicle.

Coworkers at work (larger hospital in the area) are not impressed by how things have been handled for sure.

OTOH, "stuff happens". I don't believe this is a common thing. It could be a manufacturing anomaly in that particular piece of glass. It could have been a meteor, as unlikely as that might be. The reason is not really evident in the photo.

That said, I don't think it's unreasonable to ask for assistance from the manufacturer for such a new vehicle on a glass issue, even though there's no evidence to show why it shattered. Glass is not normally a warranty item for breakage, but sometimes does get replaced gratis in cases like this.

Given that auto glass has gotten pretty expensive, especially with the added requirements for features like auto sensing wipers and some safety systems used in vehicles today, it's a good idea to consider specific glass coverage on your auto insurance if offered in your state. It's generally a pretty inexpensive rider to comprehensive coverage and is usually zero or very low deductible specifically for glass events.

In regards to insurance coverage, that is already in place.

Body Flex, improperly installed glass, or defect may be the root cause. I could not drive down the road with the windows down part way because the vibrations became so violent the entire car was shaking.

This will be an interesting venture

One other issue, they have 2 different rear glass types, Summit (and Reserve) have laminated rear glass (Or is that rear SIDE windows?) Obviously that wasn't laminated glass either way!
Only Summits show this, does anyone know what/which it actually is? I'll try to remember to take a peek at mine.

Could be anyone of those above causes you mentioned.

Did you have the rear window defroster on at the time?
The defrosters can come on automatically under certain humid conditions.
That could of been the catalyst with some defect that caused the window to explode.

Reason i mentioned defrosters is that some F150's equipped with power rear windows with defroster heating elements are also known to explode.

Don't think its that, too many computers involved these days to make it and only then find out it flexes too much, so no :)
Unibody vehicles are pretty stiff I think and not an Alfa Romeo platform either...

I believe it's all laminated glass because of crash safety. Tinting is an extra thing. But I could be wrong about that.

Are you talking about the rear hatch glass of mine? It is tempered, no laminated. Unless laminated breaks like tempered glass
I've only seen front and front side window glass laminated so far but that's on my WK2... why would a rear glass be laminated? Maybe to do with it being a 3-row and the glass being close the rear occupants?

This is what I was talking about, only the Summits show rear laminated glass, but not WHERE that is, I assume it is the side rear glass, not the hatch, but I don't know

Not quite. It was originally going to be the Giorgio platform and likely has some aspects from it, but an insider indicated a while ago that Jeep engineers ended up doing most of the platform development. (Platform is the design and manufacturing setup, not necessarily a physical thing)

Would you have some information that I would be able to read up on? I am green to Jeep.

I do not know this is an issue just defrosters and a spike like Ford has with their F150’s or a deflect in the glass or improper install
