Show us your crack (windshields)

[Krabby]

Got this impact from a stone the other day. Some asshole cut across the shoulder and sprayed rocks like birdshot.

But then, next day, this crack - which is a good ways away from the impact spot - appeared. Interesting that it seems to be in the same area many other cracks have appeared. Now that I think about it, I actually used the defroster yesterday - I wonder if that played into it?

It’s almost like it’s under tension - there’s a chip, it’s weakened, maybe a temp fluctuation, it goes - so many of them right in that same area. Crazy.

Your stone hit is about the same as mine. The crack leads off like mine. And in my case, it happened at -6c when the heating was on full (and on warmer days, the aircon puts a freezing cold misted spot on the screen in the same area on screen). So, stress caused by a weakened area does seem to fit.

I've done all I can do! New windshield installed last week. Installed Racing Optics this week, installed the foam around the live edge that Shopkeep found, also 3d printed a defrost deflector (first design). Triple pronged approach to address the three leading theories for cracking. Obviously the true fix would be a more robust windshield option but since we only have this one I've done the best I can do. The film covers up to an 1/8" from the live edge, the foam covers the live edge and the deflector keeps the bottom of the windshield from roasting. The only thing I have left to do is add the strip of clear outdoor tape to the top edge of the film. I did that on my last optics film because the car wash jets would pull it away from the glass along that edge. If this one cracks it is out of my control!

Could you share more about your 3-D printed defrost air deflector? Thanks.

This is what exactly happened to me. I was sitting in traffic for the Vail pass yesterday and the windshield was starting to ice up so I turned on the defrost with the button. I thought it was quite warm. And it had only run for a few minutes when we heard a huge snap, and there was a crack emanating from the edge right above the defrost vent. We were sitting perfectly still, and there wasn’t even any traffic on the other side. No movement at all. It definitely was the defrost that did it. The outside temperature was probably in the teens Fahrenheit. I’ve used the defrost in exactly the same situations more than a few times and not had a problem. I recently had my one year service and I’m almost wondering if the new software changes the temperature of the defrost to make it hotter. after we got that crack, we turned off the defrost function, but we still had to try to keep the windshield warm, so we use the HVAC controls to turn on the defrost vent and then manually adjusted the fan and the temperature. I felt like even at full fan and full temp. We didn’t seem to get anywhere near the temperatures that the defrost function did. The issue is that if you want the side mirrors to be heated, I think you have to use the defrost button, correct?
Because that leads me to the second issue of the fact that these Grenadier don’t handle ice and cold as well as they should. I know there is a cold weather package, but I think they need to have an extreme cold weather package that addresses heated windshield wipers, heated jets for the headlights, and something about on the left-hand drive models that big clump of ice that accumulates on the edge of the windshield.

Would be hilarious if every grenadier at the aspen even had cracked windshield

I think you may confirmed a suspicious that I recently have come across. Previously I had no trouble with HVAC but I reset the infotainment system by pressing mute for 30 seconds because I wanted to see if I could get rid of the beeping reverse PDC.

After that, the mileage counter went to 000000. No state of charge. After a couple of car starts, it went back to normal. I noticed yesterday that the heater was roasting hot from the window demister on manual when the ambient temperature was warm outside. So set it to auto it was then fine. Then back to manual. The system I think needs to self calibrate after a reset.

If it doesn’t fix it, I would reset the infotainment system again until it works. Basically the short answer is the software is a bit slow and sh*t and may cause the crack in the window from the temperature change from defrost.

This is nothing to do with the coolant or anything like that because previously it was all working fine.

You can see it in the photo I posted on page 22. It is roughly L shaped, the vertical portion is 2" tall and follows the rake of the windshield, sits about 3/4 away from window. The bottom of the "L" has double sided tape and adheres to the factory defrost vents. I noticed even when not on defrost there is still roasting hot air coming from the defrost (not full blast but enough I can feel). This deflector keeps that from hitting the bottom edge of the windshield. When I turn on the defrost it still clears the windshield but not a direct blast to the bottom edge.

The defrost was beyond hot when I turned it on. The car has an external temp sensor, there should be some logic as to a differential, and current air temp. Just starting the engine, versus sitting in traffic for an hour will give you different heat profiles. The issue is, that if you try to turn down the temp of the ‘button’ defrost, my guess is that you loose the heating to exterior review mirrors.

All cars and SUVs have issues with cold, snowy, road-grit issues - I just expected that the IG would handle it a bit better- or have a more comprehensive system to deal with ice-up issues. $750 worth of headlight washing, wiper heating, and some logic around the defrost would be nice. Plus on the LHD, that buildup of ice on the left side of the windshield get to be an annoyance. A metric ass-load of windshield wiper fluid helps, but I’d hate to run out.

You tried resetting the media centre by pressing the mute button for 30 seconds. Might take a a few days for the car to self calibrate.

Like this? Two days old.

My windscreen is getting replaced at no cost on my insurance.
I stopped counting the stone chips at 40.

I saw this recently and wonder if the lack of “dots” is the problem

No
The abundance of rocks is the problem

I was thinking of all the apparent defroster cracks that have been posted.

So Ineos attempted to create windshield glass from scratch? They haven’t discovered the dots technique yet?
