I bet the loads bike racks experience on bumpy roads are pretty significant and I would lean more towards the rack flexing and the bike moving in the rack and contacting the window. The bike is clamped in by the wheels, and the tires themselves flex and deform under loads. The bikes have suspension so they compress, and that will occur under a load such as the rack bouncing up and down. Everything to me points to the bikes hitting the glass not some random rock. Even if you think the bike can’t hit the glass by eyeballing it I would bet that rack and bike move all sorts of ways you wouldn’t have thought of doing 40mph down a bumpy dirt road.

Obviously we're all kind of speculating here, but I can assure you that the way this rack is set up and the way bikes work, I think it's virtually impossible to contact the vehicle with the bike with this sort of rack system. Which is very very much intentional. The bike I have is worth a fortune and so is the vehicle so having the two come together is a pretty big problem. The way the rack is set up is hard to see from the side but the wheels on the truck are lined up with the tray which is significantly higher than the rest of the rack. I showed it to a structural engineer and he's pretty unconvinced that a rock would have done it. He was definitely more convinced with the torquing theory. For what it's worth.

Even my 1-up rack that's basically on a torsion arm doesn't bounce enough towards the vehicle to do that.

Here's a picture to illustrate. I was driving about 40 mph when the window blew out. The trajectory the rock would have to take in order to hit the window is pretty much impossible. The wheel isn't aligned to the rack and the trays are way too high for rocks to hit.

The Count wonders if you were near a grassy knoll? Perhaps there was a second rock?

That's hilarious. When I stopped and got out of the vehicle the first thing I could think of was that someone shot at me. I actually looked around to make sure that there wasn't any exit wounds. I do live in New Mexico...

To finish this story, I was left with the impression from CS that I would have a decent chance of getting this covered by Rivian. I also was led to believe that it should be relatively quick. The service contract I got sent said 0 dollars on it. Then on the day I was supposed to have it there and someone was driving it to Phoenix for me I got a call from the SC and was told that they bring all the glass work in on Weds and then spend all day thursday fixing them and I could have it back late thurs. Not at all what I was told. I also got a new service contract that said 750. Later I got a call from a tech that said that there was no way they would pay for broken glass. He also said that Safelite has OEM parts and would be a way better bet because I have to pay for it anyway.

I told my guide about the disconnect in information that I received that caused me to make this decision and he apologized profusely and gave me some free t shirts.

Truck looks great. I'll try not to do whatever it was I did again.

Just curious, how much did you end up paying to replace the glass?

671. They didn't charge me for labor. I submitted the claim to state farm
