Every ping on roof or front glass, acorn, bug, comet, you name it.... Just waiting

My roof cracked on its own. I didn’t touch it or put any weight on it.

could you get a picture of the identification markings on the glass? Curious who the supplier is.

We already had a windshield replaced due to rock strike.

However, on a recent road trip, our R1T was pelted with hail on three occasions. Once while charging at an EA station. In Moab we had a storm come through while we were out on the trail that generated intense pea sized hail with a few of the stones I saw being dime sized. Naturally I though all the glass is ruined… That was 10 days ago and, as far as I can tell, there is no damage to any of the glass (roof or otherwise).

Looks like you breathed on it wrong. Please let us know if Rivian takes care of it for you or gives you a hard time. There have been way too many reports of spontaneous roof cracks for Rivian to expect customers to pay for these replacements.

My theory is that it’s from slamming the door shut. The passenger side door is difficult to close, and maybe that put pressure on the roof glass.

…And then there were two (automotive glass companies that suck).

When two suppliers have the same issue I have to think the spec is weak rather than manufacturing defect.

It looks like Tesla uses them. I tend to think the specs is the issue.

Very possibly but it’s far easier to simply jump to conclusions.

Could it more simply be that the robots that place this glass into position had a day that calibration was off and tolerances were too tight and now any flex of the body cracks the glass in those trucks built during that particular time? Just spitballin....

I highly doubt Rivian is doing anything new and interesting with their glass spec. I would think it's something to do with their installation process resulting in an uneven load distribution over the panel's edges.

Or the robot that draws the bead of adhesive/vibration damping material prior to the glass being put into place was out of tolerance and left spots where there was insufficient material during installation.
