Shattered Side Window Glass Disappointment and $350 Replacement Cost

[carsly]

This situation has nothing to do with Tesla. Sharp objects, with high density and some mass traveling at high speed break glass. Is this a joke post?

$350 isn't bad at all for the glass and labor. I think your beef is wildly misdirected. How about not firing rocks at your vehicle?

For this very situation, landscapers frequently include verbiage in their contract such as "not responsible for incidental damage inherent to the task" etc. If your dirt-based lawn includes rocks, then rocks will be thrown no matter who is pushing the mower.

Survey says the advertised "strength" of the CT glass is false. My passenger side window spider shattered from a rock being shot at it by the landscaper's mower as he ran over it. I'm pretty disappointed, given the representations made about this glass. It's WTF-sticker worthy.

Also, Tesla is charging me $350 for the repair. I'm about to raise holy hell and tell them it should be covered by the warranty, as it was clearly weaker than hail and a 70mph baseball ?

There is a huge difference between a baseball being thrown at a piece of tempered laminated glass and something like a rock. Go look at any escape tool you can buy on Amazon and you’ll see a pointy end.

The shape of an object affects its ability to break tempered / laminated glass primarily through the concentration of force and stress distribution. Sharp, pointed objects can concentrate force on a small area, increasing the likelihood of initiating cracks and fractures in the glass. The geometry of the object also influences how stress propagates through the glass, with sharp impacts causing more localized stress and potential for breakage or cracking.

These guys certainly wish it was easier to break away...

You are confused. The landscaper is liable for cracking your glass not Tesla. If the landscaper believes it should be covered under warranty then they would file a claim with Tesla, not you.

This really sucks, sorry about your window. As a recovering engineer, it’s hard to tell how much force was exerted on the window by the rock. The speed, weight, and surface area all matter in that equation. A baseball might spread the force out over an inch, where as a rock might be a few millimeters at a point. Resulting in the force being substantially higher and cracking it.
it’s possible this same rock goes straight through another vehicles glass and could injure occupants.

Overall, it appears the glass did what it was supposed to do, absorb the force, and if given enough force, permanently deform in order to stop the projectile. This sucks! But objectively, without more details, we don’t know if the window wasn’t strong enough. Think about actual bulletproof glass. Bulletproof glass is meant to break to keep the bullets outside. They don’t just bounce off with no damage. But the people paying for new bulletproof glass still won’t be happy at the cost!

I don’t expect any of this to make you feel better, but engineering is complicated, so Tesla hate may not be as warranted as it seems. Sometimes this stuff just happens and it sucks. (But you can still be mad, just aim it in the right direction.)

True, in that case it comes back to the landlord's home insurance section for contractors.

My landscaper broke a home window. They paid to replace. I now mow my own lawn. I like the exercise. They used gas. I don't. Cut it like you own it.

Are we really talking about this? Seems so.

OP should consider themselves lucky the rock struck their Cybertruck and not another landscaper or passerby like a child. The $350 would be the least of your worries since the hazard was not cleared by you from your lawn and it was your landscapers who fired the projectile. Accident, sure. But as the homeowner it is your responsibility to keep the lawn clear of hazards and debris.

My Mom used to work at Snapper Power Equipment. She'd talk about how the mower decks would be cut open by QA and they'd drop steel balls in there to make sure the mower would eject them lower than some number I don't remember. But, it relies on people using the mower right and keeping the deflector down.

Too many people mow with them held up or just remove them altogether. I get that it's easier to mow but you take an awful chance of throwing rocks, sticks, and the devils own torture devices mini-mace gumballs.

Damn those things!

You can roll an ankle if you step on one and lord help you if you are barefoot!

They roll unless they are under a trashcan tire. Then, they just f$%kn slide around making your trash can pull to the right harder than a walmart cart with string wrapped around one wheel.

Don't get me started on goat heads!

Since we are talking about yards anyway... We parked the camper at Fam Camp at our new Air Force Base home, unstrapped the bikes, and the kids rode out into the drive... A car slowly approached, so the girls rode to the side of the road and into the grass probably less than 10 feet in total grass distance.

Four flat tires. Four! Within minutes of arriving in Utah. Four!

Dog paws... My poor doggo... pains me to remember pulling goat heads out of paw pads.

ANYWAY, yeah! What were we talking about? Oh yeah, some form of "My window cracked when a rock hit it." Yeah, that sucks. Sorry to hear about that. If the landscaping company doesn't pay, you will. Tesla won't.

I suppose making the jump from glass to crack to grass makes sense in some circles.

Insurance claim will pay. No deductible
