You might want to look into windshield protection films. I think there are several types now. I used one when I ran my car on the track. Not a complete solution, but it does help avoiding small chips.
It would be useful to check the oil level on the dipstick on a Bronco just off the truck or rail car from the factory. At least then we will know what the factory is doing. Someone with a new Bronco , please do this and tell us.
You have to think that they will as soon as they can. For them “More Broncos = More $.” They have a huge investment and not much return for various reasons. I am sure this is a big topic in the board room.
Of course,, I have. Done solar cooking too. Just seems hard to imagine things could lineup that well to melt his roof in that spot. He should move it someplace else to test. Maybe put something that melt easy in that same spot to see what might happen.
I live in Las Vegas, it is not unusual to see over 110 degree days in the summer. So, I come out to my Bronco (if I ever get it from Ford) and the top is melted into the Bronco? Sounds like a bit of a design problem.

Zip ties are great things, but do not last forever. If Ford or the dealer does not offer a better fix, I would use one of those rubber coated metal clamps. Harder to do, but will last for the life of your Bronco. I will do this, if Ford ever decides to build my Day 2 reservation for my 2...
In some European countries require a right tail light with fog lights. My Porsche Cayman did this and I thought something was wired wrong, but its how is was made. I thought it was strange at the time. It should just be a programing change.
I appreciate when someone adds a real reference to their answers instead of stating what they think the answer is based on their understanding or misunderstanding. Thank you.
