2024 Buick Envista

I purchased my 2024 Buick Envista in 3/24 and not too long after the windshield had a spontaneous crack that started in the center of the glass, and resembled a backward letter 'L". Driving around, I noticed more Envistas on the road, seeing a total of 12, 7 of the 12 had cracked windshields, furthering my suspicion that this is a manufacturer defect. I took note that each vehicle had different license plates as well so it's not as if I was noticing the same vehicles over time. During my time of researching this info and being told parts were not available for my windshield at the time since it was a newer model, on my way to work, a truck in front of me, in another lane, had a load of uncovered sand that flew off due to the wind of course, and hit my windshield in a spray like mist. Well, there had to be bigger pieces of rock in it as it nicked the top of my car. Please note, my windshield had already cracked at this time. GM reached out to me and I explained the situation. I also uploaded photos of the crack to an email the GM representative gave me. Eventually, GM called me back stating I needed to take the vehicle to a GM dealer for evaluation.. The manager came out, took a fountain pen, and started digging into the crack, rocking the pen from side to side. This caused what was initially a thin solid line, to now a line with a pinhole in it. He then says, "I'm calling GM and telling them you did this". I said excuse me, I just watched you dig your pen in my windshield and rock it back and forth. He denied digging in my windshield and told GM It was my fault, leaving me to foot the bill. I say all this to say, it is no coincidence that several Envista owners had the same thing happen with a random crack without a cause. I took my vehicle to another GM dealer and the service tech admitted to seeing multiple Envista windshields cracking on their own. This needs to be investigated thoroughly before someone is injured or killed.
