Very helpful thread. Tried calling my local dealer (Fredrick CO) 4 days ago and unable to reach service associate after calling each day and leaving multiple messages (is there an employee shortage there?). Now beginning this same process with the Lexus in Lakewood CO (earllier post had great service from Lexus Lakewood). Good know know from this group that the squeal is a known Lexus issue and a resolution is available. It is not only embarrassing backing up an expensive new car to hear this, but really sad that Lexus didn't resolve this themselves. Bought my '25 in July and has 2k miles. This started happening at 1500 miles and occurs EVERY time I back up after an overnight rest - temp/humidity doesn't matter.

I suggest you print off that LTSB, attached in Jabber's first post in this thread, and take it with you to speak with the service manager. The dealer can't do anything for you without actually verifying the issue, themselves. Once that happens, they'll order the parts and make an appointment. I had mine repaired in early August, and the parts still took a month to arrive at the dealership. It's a one-day repair job. I dropped my GX off around noon, took a loaner car home, and then went back the next day to pick it up. No mo' squeal!
Update: Called ahead to ensure the brake kit was in stock (one left). The kit is identical to what an earlier post listed. No charge. Squeak while reversing has not returned. Thanks to this GX Forum I was able to learn this is a known issue with a known resolution covered under warranty.
Just had my brake anti-squeal repairs performed today! Lexus replaced front pads AND rotors, installed shims, etc. along with a tire rotation and oil change as part of the 12 month service. I noticed the warranty invoice was over $1300, paid by Lexus.
Tomorrow I will perform the big test, backing down my driveway (downhill) and not wake-up the neighborhood!

I bet you $1 that it's quiet now. Mine is!
