MY FRONT WINDSHIELD HAS CRACKED IN A MANNER THAT IS UNSAFE. IT HAS 2 IDENTICAL CRACKS ON EACH SIDE. SMALL ROCKS HIT THE GLASS AND CAUSED INSTANT CRACKS WELL OVER 8 INCHES IN LENGTH. I FEEL THAT THE GLASS IS NOT IMPACT RATED CORRECTLY OR TOO THIN. I HAVE NEVER SEEN A WINDSHIELD CRACK LIKE THIS FROM THE IMPACT OF A SMALL ROCK. THERE HAVE BEEN MANY COMPLAINTS ON ONLINE FORUMS OF THESE WINDSHIELDS CRACKING ON THE NEW BRONCO.
At present no incident has occurred. I am in the process of purchasing a 2021 Ford Bronco with the associated VIN number. The vehicle was delivered to the dealership, but as per guidance from corporate they are unable to now sell the vehicle. Ford has not determined a course of action and I am unable to purchase the vehicle. This is wholly unacceptable.

Windows are constantly getting uninitialized so that they don't bump down on opened to allow them to close properly with the frameless doors. This leaves a gap when closed and additionally they will automatically go all the way back down any time they are rolled all the way up. This is very hazardous when driving and needing to close the windows as you're forced to look backwards to see when they get close to the stop and release the button before it hits the top. This was reported to Ford on greater than 10 occasions since I took possession in Jan of 2022, first in March of 20222, and impacts all 4 windows. The dealer can resolve the issue by reinitializing through the computer they can plug into the vehicle and have installed some software updates as well as replaced some of the modules but the issue resurfaces a few days later. Sometimes I am able to resolve using the full reinitialization sequence that they shared with me when I had it there in April of this year but sometimes that fails. Prior to that it would eventually resolve following just a holding up and down of the button for approx. 5 secs at top or bottom. Here is a record of the occurrences with window impacted since I had it in the dealer in April of 2025. 5/2 passenger front (pf), 5/7 drivers back (db), 5/10 db, 5/12 db, 5/15 pf, 5/16 pf, 5/29 pb, 6/13 db, 6/17 pf, db, df, 7/13-7/30 pb, 7/24 db, took to dealer for restarts and software updates 7/30, 8/1 db. I kept a similar record in 2024 4/5 df, 4/6-10 db, 5/7 db, 5/18 pb, 5/22-6/6 pb, 6/6 df, 6/7 pb, 6/9-21 pb, 6/25-27 pb, 6/30-7/8 pb, 7/10-13 pb, 8/1 pb.
