Part of My Roof Shattered / Cracked

[pt19713]

On the Facebook MachE group and woman’s rear window shattered just sitting in her garage, Could possibly be a defect?

Remember when this forum made fun of the Tesla Model Y door window shattering (about 2 months ago)?

Seems to be spreading across too

It will. Once it's cracked, either due to internal stress or an external force, it's going to spread. Call the Ford dealers and get the ball rolling. Please let us know how this replacement goes.

Shattering while driving and getting hit by an external source are two very different issues. There'll be cause to serve crow if stress fractures and pop top glass ceiling occur on a very regular basis.

Makes me wonder if it’s worth doing Xpel over the glass roof.

Interesting ....probably works better than window tint film (which seems thinner) in holding shattered glass..

Right.

Thinking about it - I have not really had situations in the last 30 years where an impact occurred on my ICE car roofs . Even it it did happen it probably was not big enough to notice. I certainly never had to get anything fixed. But they are metal roofs with smaller glass moon roofs. But with glass roofs, I am thinking that even a small rock at highway speeds impacting the roof at the right spot can potentially crack it. And sure insurance will have to cover it and not Ford unless its a design or mfr related issue which would be hard to prove

The post I quoted referenced a window shattering while stationary. I'm not referring to the original post and the roof.

If there's enough demand, companies like this will make product for the roof. Currently they focus on windshields.

I'm not sure a film coating would keep it from cracking no matter what caused it. Might keep it from shattering as bad, or from little chips. I too have not had a roof crack chip or shatter in decades of various size glass roofs. And if anything did hit it like a pebble that hots a winshield, I would not expect to see this kind of result. Anyway, I called and sent a pic to my dealer. I expect this isn't the sort of part that comes from a regional warehouse, and will have to make the long trip from Mexico where they are built. I am so dreading them pulling my roof apart to replace it. I can't imagine it will ever look the same. The alignment at the factory is even iffy.

Yes, I know. The fact is that until stress fractures are as common on the MME as they are on Tesla MY, there's no reason to be eating crow ... just yet. In this case, this was an impact issue.

If the dealer can pinpoint any kind of external impact, then it becomes an insurance problem.

It should be Ford's or the dealer's "insurance" problem if the "impact" occurred prior to buyer delivery (as happened is my case). Proving it, however, may be problematic.

If this was an impact, ot would have been extraodanrily minor to the point that I didn't even hear it. And if it was a little piece of stone or gravel flung up and hit the top, the glass should not have been so fragile as to do what it did. Even a winhsield can handle some pretty big rocks without shattering. Yes at some point all glass will break and splinter, but it has to be a pretty big blow to do that. I once had a giant pice of ice from a truck come right through my winshield when driving, but that was kinda noticeable..

Geez sorry, bro that sucks. Yeah, it's a contact hit something smacked it.

Yikes. Possible design flaw if that leading edge is protruding up into the wind stream. Don’t have mine yet so can’t tell if it’s raised or flat. Insurance at a minimum. Maybe worth reducing our deductibles for this car!

Or it could have been delivered to buyer with a "defect" as mine was (see pic). Fortunately, I caught it at delivery. Ford is currently reviewing the situation.

I would not be too concerned about the replacement quality. In the space of 2 months, my wife's Highlander windshield took hits twice (So Cal is notorious for freeway debris). Took it immediately to the dealer (once in Ventura, once in San Diego during a vacation trip). The dealer took it over to a collision repair shop known for quality work, got the car back the next day with a new windshield, could not tell anything had ever happened, and the sensors all worked perfectly. A roof window will be far easier since there are no wires involved. There is a road hazard windshield clause in my insurance, so the deductible on the claim (notified insurance immediately with photo) was only $100 I believe. A window/windshield/roof window repair is far less problematic than a bumper repair where frame mounts might be involved.

The front center part of my roof shattered starting at the front edge above the Ford symbol and going back in a fan about 15" or so and about 20" wide in different directions. It hasn't broken through into the stuff around the rear view mirror yet, but it's real weird. Not sure how my dealer will even begin to replace this. If it was hit by something it's news to me. I didn't hear anything hit it, but who knows. Starting to think glass roofs are a bad idea. Sad though.

I also have a crack on my roof. I have been going back and forth with Ford for over two weeks now. I first called Ford and they told me that it was covered by warranty and I could take it to any Ford dealer and they would fix it. I took the car to my dealer, they took pictures and told me that it was not covered after they checked with Ford. The only way to see the crack is in the sun light. I believe that this probably happened during transport. But of course I cant prove it. I also picked up the car at night. You can not see anything wrong from the inside of the car since it is all covered. I have since called back to Ford and have a "case Manager" (not sure her title). She has been talking with the dealer. As of now she is trying to find out about the warranty. The crack has grown since it first was spotted. My crack is basically in the same spot as agoldman's. I have not yet talked with insurance company, waiting on Ford to do the right thing.
