Yeah, starting to wonder this myself, because it starts right underneath the windshield wiper and extends up a few inches above it. But I'd imagine the dealer just going to blame it on a rock anyway.Bad luck, sorry to hear. And a bit surprised that your car must have had unrelieved residual stresses in the structure upon delivery. The stresses are normal, but manufacturing processes take this into consideration with remedial steps. But in your case it appears driving the car for a few weeks relieved remaining stresses and the windshield couldn't take the settling adjustment of the body. I would think that's a warranty repair...
I just had my new Cayman on a trip of several thousand miles... including a really rough winding road north of the Navaho Reservoir in northern New Mexico. I took it as fast as I dared and the road bounced the car around pretty vigorously. My windshield survived without cracks, so I guess there were no residual stresses in mine!
What I was thinking. If the crack was caused by a rock there almost has to be a chip/star/impact area somewhere along the crack.I'd guess that a rock that cracked a windshield would leave a chip whereas a stress fracture wouldn't--but that is a guess. It might pay to ask a windshield expert.
exactlyI live in the Phoenix area too. My 718 does have a few chips that have not expanded, but I have replaced several windshields on previous cars from stones thrown from another vehicle. The problem seems to be that large trucks delivering lawn stones (most people don't have grass) drop some stones on the highways and any vehicle without mud flaps and more than half of their rear tire showing throw those stones at your car and windshield. Mud guards should be required on vehicles with more than 50% of their rear tire showing.
But your Jeep also has a windshield that is totally flat, which enhances its strength ... and a hood, fenders, and grille that will intercept 95 percent of what bounces up ahead of you.I swear my Jeep has gone through less windshields on the same commute since 2014 and has a near vertical windshield
Same here. No signs of a rock chip, I assume it is stress related. Starts under the wiper and extends upwards. Mind sharing a picture of the crack ?Yeah, starting to wonder this myself, because it starts right underneath the windshield wiper and extends up a few inches above it.

I'll try to take one soon.Same here. No signs of a rock chip, I assume it is stress related. Starts under the wiper and extends upwards. Mind sharing a picture of the crack ?
Stuff flying off trucks or cars is illegal here in Australia.:xI'm blown away that trucks are free to let sand and rocks to fly off the back. They even have the nerve to post a sign on the back saying that they are not responsible for window damage. At least that how it is in central Texas.
