Who is Chrysler's contractor for auto glass? Aside from the near vertical windshield angle, I am suspect of the window glass chemistry. Soda-lime-silica glass can be made optically 'clear', but brittle. It sounds as if they have altered the chemistry to make the glass less expensive and not tempered properly, making it very brittle and thermally sensitive.

My CJ windshield was never as sensitive as the TJ/JK window glass seems to be.

Careful, some cheap windhield places use slightly tinner glass than OEM. Make sure they offer at least an OEM style replacement, that has all the same qualities and specs as factory glass

And now on my drive down to the Outer Banks today one of the star lines started spreading and is about 4-5 inches long. Luckily their is a Safelite down here who can replace the windshield next week.

And ALL the Jeep aftermarket bug/stone shields are INEFFECTIVE .

THEY'RE WAY TOO LOW !

It'd be a bit ugly, but a design that is 5-6 inches tall would stop many a flying rock, not all, but many. Back in the 70s, they were all that tall. Now, ALL the current crop are nothing more than decorative. They may protect the area on the hood edge they cover ; nothing more.

The driver sits up high enough to see over .

I guess this is another reason why full glass coverage costs so much on a Wrangler.

Luckily in Massachusetts windshield replacement is standard on all car policies.

Here we have a place called novus. They drill a small place to keep it from cracking and fill it. Mine was done over 10 years ago still perfect. Cost me a deductible 20.00

That stinks. It's even deductible free here. People still don't do it because its still a pain to go get it done.... My daughters dad has a jeep with a cracked windshield and its been that way forever!!!!

So even when it's free laziness still factors in for some.

Me... I take a gift horse ....

Take care!

Well even in FL if you have full coverage the front glass is covered by law I should probably not say this knock on wood but I have had my JK 2yrs in Sept and never had a crack in the windshield I must be lucky.

I didn't realize so many were having cracking issues. My uneducated guess is most likely cost cutting the windshield chemistry/thickness/tempering. I also think thinner steel in the JK's would make everything flex more setting up stress where a spontaneous crack seems to appear out of the blue. Also some windshield frames might not align properly or maybe over ( or under ) torquing the bolts. I can see it's probably a complex issue with not one single weakness to point to, yet the quality of the glass is probably most suspect. Yet another reason to possibly make a non folding windshield in 2016.

The second day I got mine a semi threw a stone that put a substantial divot in the middle of the glass on the drivers side. It sounded like a rifle shot. The next day I went to an auto store and bought an epoxy windshield repair kit for $15.00. I followed directions. Afterwards I couldn't find the divot. It's been almost a year with no problems.

I didn't have replacement insurance then but do now. Still, I would repair a divot before it turned into a crack if I could. Luckily the divot didn't break the inside glass, so no fracturing. Once the glass fractures the only remedy is replacement.

Although there may be something to the fact that the glass may be thinner, the main fact is the angle of the windshield. When a rock hits a more perpendicular windshield it does not glance off. It is a more direct hit resulting in major stone chips and cracks. Any vehicle new or old ie Hummer, big old transport trucks will have the same issue.

I've went through one windshield in the two years with my JK. Like many others have said, its the angle of the windshield that makes it vulnerable to flying debris

I'm opting towards flex or pinch points in some of the windshield frames. It isn't consistent in all of the jeeps, but there is enough people having problems that there has to be some defects in some of the frames causing the issues. These failures seem to be trending in the same locations on most of these, so there has to be an issue. Now whether or not Chrysler will live up to the problem is another issue all on its own.

I doubt that they will do anything unless they are forced into it with a class action suite, or are forced into it with other methods. People shouldn't have to use comp claims to replace this many windshields with stress fractures. You are jeopardizing your insurance rates, and causing insurance increases with this problem, it is a manufacturing issue not an insurance issue.

^ I knew of a guy with a TJ that had a stress point in the bottom driver's corner. Every time he got a new windshield it would crack within weeks from that corner. He was about to give up when someone said that he needs to fix the problem, not the glass.

They pulled the windshield off and scrapped everything clean and then used a Dremel to really clean the edge of the metal where the windshield set in. Taped it off and painted it again and once cured put new windshield gum on the inside frame again and replaced the windshield. He never had an issue since, except for rocks...

I was going to ask about this, in a way, too. I had a regular chip (from a rock on the expressway) on the lower part of my front windshield, passenger side, and wanted to get it fixed but don't want to replace the Jeep windshield because it has the cool design on it.

What's my best course of action here?

Insurance is replacing mine with an OE windshield, so I will still have my cool logos and no more crack. I just had to request it instead of the aftermarket glass.

6 pages and no one has blamed Obama for this??

If chrysler wasnt offered bail out money, they would have worried more about the build quality and materials, so if Jeep windshields are cracking, then it's 100% Obama's fault! Period!

Allstate covers OEM windshield replacement. We have a Florida policy, so it was 100% free replacement with Safelite, and its backed by Allstate's guarantee.

Make sure you check with your insurance company. They may surprise you!

Cool

Get use to it, changing windshields is a normal on a rolling brick. I have a 2012 with 20k and have done it twice. Welcome to jeep ownership

I'm getting ready to get mine replaced...3 foot plus cracks (two have been drilled..not even bothering with the third one). I wish the glass was tougher, I had an H3 (same vertical windshield) and I had a lot of rock chips filled but it never cracked...this glass seems ultra brittle.

I'm sure they could spec glass much tougher if they wanted to.

Windshields arent tempered on any car. Thats why they can get small cracks, unlike side or rear glass...which will simply explode into a bazillion little sort of sharp sort of not sharp cubes. Imagine if a windshield did that while driving.......

I think its just the near vertical angle. We have the same problems with semi trucks. Atleast trucks with split windshields can get half a windshield for half pri

Ive never cracked a windshield on my jeep yet. My dispatcher just keeps on cracking em.

Any time anything impacts the windshield and doesnt break it, theres a potential it has weakened it. Then a much lesser impact will break it.

If youre careful about not tailgating people it helps. I drive slow in my jeep because im enjoying myself.

You could spec it higher when you get it replaced and see what happens. Guardian is one of the best.

Great way to start a new year. On the first REAL day of the new year I'm a minute away from work and notice the crack. I thought it was a stress crack but after looking real close at where it started its from a tiny ding. Probably from the rocks and salt they put down with the snow storm heading in. To make matters worse. I go to grab lunch get back and about the point I noticed the initial crack I'm wonder if this crack was getting any bigger its goes from the 8-10 inch crack covering the passenger side to going all the way to my line of vision on the drivers side.

If it wasn't for reading this thread and knowing these things happen while waiting for my jeep to come in I'd probably way more pissed than I am now. Least I made it farther a long than some of the other people posting in this thread.

This is the best strategy... I got pelted by a gravel truck last week. I was four or five car lengths behind and moved over to the fast lane. I wasn't soon enough though.

Need to think ahead...

Mine cracked back in March 2013 or so and I still haven't fixed it.
