Cracked windshield already

My crack spread real quick. Temp changes or even flexing of the chassis will worsen it. Mine didn't need to be recalibrated, but one of the camera/sensors did have an issue. Dealer fixed it for free.

The original crack happened in a rainstorm on Friday night. Then on Saturday, the hot sun came out, and the TLX was parked in a parking lot for 2-3 hours. When I came back out to the car, that's when I noticed the crack in the windshield had spread substantially...

Once you start a crack in glass (or many other materials as well), the crack acts as a stress concentrator at the tip of the crack, which can lead to further cracking as the release of strained energy overcomes the energy of creating new crack surfaces.

I'm guessing the thermal expansion of the glass in the hot sun offered that additional stress that allowed the crack to propagate further on the windshield.

See Griffith Crack Theory on a google search.... e.g., on wikipedia

https://en.wikipedia.org/wiki/Alan_Arnold_Griffith

Although developed for metals (see section on metal fatigue), it applies equally well to glass. Introductory texts on materials science will also discuss this.

10 minutes ago, 400miles on odometer, a car in front of me lost a big rusted bolt... now I have an impact on the hood and a 1/2inch size rusted impact on the windshield, just in the center down on driver side...
Like we said in Quebec ... cal...sss de tab...nak.....

Road debris is so maddening. There's not a lot to do about it really. I've tried to stay further back from cars in front of me but this is apparently just an opening for other cars to change lanes and move in front of me.

Hopefully it doesn't crack and spread.

I know what you mean. Take it to a detailer to see if they can fill and polish it out.

Do you think a high pressure washer would take the rust out of it?

I expect it to get rid of rust color (most annlying than the scratch).

If I try to make it polished I am afraid to fix definitively this rust color inside the scratch...
Maybe later, but I don't know if polish can fix a scrapped first sheet of glass. I may put it a try when/if rust is out.

I painted the scratch with the pen yesterday evening. (2 pass one, with separated clear). About windshield, I had a bad experience with a repair on another car... I will go there only if I have no choice. (a crack repaired with resin, the thumb was not well attached and spit some resin over all the windshield - I had traces for years after that everywhere on the windshield... Crack was repaired. but all was scrap job done.

I bought mine in November 2014, after 3 months I have mutiple rock chips and a cracked windshield. There is no rock chip near the crack though, think I should take it in and see what the dealership says?

It's going to cost $1000-$1100 CDN to fix it in Edmonton, $900 for the glass and the rest us labour and tax. I will say that I haven't replaced my windshield yet in case they were manufacturing faulty windshields with the first run...

It never hurts to check with the dealer but if you've got some chips it might be a tough sell even though they aren't around the crack. In a past vehicle I had a windshield crack while I was washing it. I took it to the dealer and they ran a pin/nail down the crack. If there was any type of impact along the crack (which they would find with the pin that may not be visible to the eye) it wasn't covered under warranty. I ended up having to pay for a new windshield.

Let us know how you make out though. You never know........

Windshield is replaced! From what I can tell, it is as good as new. The lane keep assist, adaptive cruise control, etc, all seem to be working fine.

The key to ensuring you get a good job done on the replacement windshield:

1) Make sure you have glass coverage with your insurance. This would have been an $800-900 job without coverage.

2) Make sure the replacement windshield is OEM from Acura (I'm not sure there are other options yet, but I'm sure there will be soon). Most glass coverage insurance will cover OEM replacement

3) Make sure they don't disconnect the wiring on the camera / sensors, etc when the remove them from the windshield. You can see them hanging down but still attached, in the below pictures.

4) Make sure nothing is powered on when they do the replacement


I was quite nervous, but overall, happy with the end result. The glass repair took around 1 - 1.5 hours, and they did it right in my driveway. Fortunately, the technician had replaced several TLX windshields before so knew what he was doing.

That's great news about the windshield replacement. :)

The part about the tech replacing several TLX windshields is kind of scary. :(

So exactly 1 year ago today, I creaked this thread after my windshield developed a mystery crack.

So guess what I got for a 1 year anniversary?
