Bad Luck or are JK Windshields Prone to Cracking?

My latest of 5 Jeeps that I've owned is a 2009 Sahara Wrangler Unlimited. I've owned one YJ Laredo, two TJ's, and a Cherokee. I've never had a problem with the windshields cracking from stones until I got my JK. I'm getting ready to replace my fourth windshield in less than 8 months! All of them due to stones hitting the windshield because it's obvious where the impact was and crack started. Is this just my bad luck or a design flaw in the JK? Has anyone else experienced this? This is getting expensive to pay $100 deductable every time. Thanks.

I got a rock crack the first week I had had it. Luckily it hasn't spread and I haven't gotten any more in the 6 months after.

I haven't gotten a crack in mine yet, but every time I drive it sounds like it. I guess the pressure difference causes the windshield to contract and expand and it makes a sound like a crack should have appeared across the glass.

I've only been hit by stones a couple times, and nothing here, but I've heard the windshields are easily cracked. I've made it a point not to drive behind dump trucks or get too close on certain pavement types.

With the JK, they curved the windshield to try and help with aerodynamics as well as rock chips. I've had several rocks hit my windshield at highway speeds and I haven't had any chips or cracks. You should try one of those guys on the corner of a gas station that fill in the chips. It may be cheaper and prevent the chip from turning into a crack.

Got mine repaired by safelite today... And I can't find an auto insurance company in Alabama that waives the glass deductible. It's always whatever your comp is...

I have a 2001 TJ and a 2010 JK Unlimited. Not sure if it's just bad luck...but these appear to be FOD (foreign object damage) MAGNETS! Probably because they are slightly less aerodynamic than full sheets of plywood. TJ: Rock strike on the windshield in the first two weeks of ownership. One week later the the strike spider-webbed the whole windshield.
JK: Rock strike on the windshield in the first week of ownership. Learned lesson from TJ. Had safelite repair the chip within two hours. Seven weeks later. rock strike on the driver's side windshield pillar. Result: pencil-eraser sized chip in the paint right down th the bare metal.
All three rock strikes occured on I-5. Two in Seattle, one in Tacoma. I should sue WA-DOT. I think it's because they won't enforce seasonal use of studded tires and the roads get chewed to pieces.

Never confuse effort with results......

Look at the angle of the JK windshield! It's gonna take hits that glance off most others, but, small "bullseyes" are often fixed by most every insurance co at NO charge NOR deductible w/ filler and pressure and it works., but, once the crack starts runnin' it's just a matter of time....

I got one on the lower passenger side. It spread out faster than peanut butter on a sandwich.

Two windshields so far. One rock and one piece of debris from a truck.

i have two wicked dings on my windshield frame and one nick on the windshield itself.

the ones on the frame..holy cow.. I'm so glad they hit the frame! massive one took a chunk of paint the size of 3/4 a dime, and the other is under the windshield and looks like someone punched it with a big center punch.

My first one cracked for no apparent reason, no stone chips or anything that I could find. I had a local windshield shop replace it and the new one had a whistle from 35mph up to about 55mph so they put in a new one for me and the new one cracked when I let the wiper blade slap down on the windshield after washing it. Again the glass shop installed another one and I got another whistler, they took this one back out and installed a different type of seal that flush trim going around the perimeter that seemed to eliminate the whistle. All of this occurred in a matter of about a month and was very frustrating, thankfully the glass shop was very accommodating and was very expeditious in repairing each time.

Like most of you guys, I also have had a windshied replaced. Mine was caused by a stone that hit at the lower edge of the glass and spread in a long line. The glass guy told me it is because there isn't any metal trim around the glass and the slightest ding on the edge of the windshield will usually result in the long line crack. Lucky for me, here in AZ, regardless of your glass deductible the replacement doesn't cost any $$ if the damage happens within the state. State law.
