Windshield spontaneously cracked

DenaliDH · April 17, 2019

2018 Sierra 1500 Denali - for the past few weeks I have been hearing a popping noise that kind of sounded like small rocks hitting the windshield but their were none. I thought it might be expansion/contraction of something in the dash. Last night while driving home on a smooth road, I heard three pops and then a very loud snap. Windshield cracked from the top in an arc around and under the rear view mirror/ lane departure camera pod. No rock chips at all, just a crack. 7k miles.

Anyone seen anything like that? Chronic problem or fluke? Do I take it to dealer or glass shop? Does the camera need to be recalibrated after a new windshield?

Thanks!

You should be fine as far as your lane departure.

You could try asking the dealer to take care of it, you're in warranty. Otherwise your insurance should cover a new windshield with no charge to you.

My 2014 had Pilkington glass, and I never ever had a problem with any of it. Tons of highway use and never got a chip or crack.

My 2017 has Vitro glass, and I got a windshield chip within a month of buying it.

I do know that Mercedes Benz glass is Pilkington, so I do believe that's better quality, but I'm no glass expert.

You probably won’t believe me but that sound probably wasn’t the windshield. My 015 does this now & then even out in the middle of nowhere with nothing around so I was like WTF. Then I found several threads on here of others reporting the same.
