Brake Squeaking Noise Problems of Toyota 4Runner

I recently purchased a 2019 Toyota 4runner from stadium Toyota. In the beginning of November 2019, I began to hear a squeaking noise coming from the car when ever I would back-out of my garage first thing in the morning and lightly release the breaks. I recorded the noise and scheduled an appointment with the dealer. I showed the video to the service technician, who acknowledged the problem but was unable to replicate it. 2 days after the service, the squeaking sound, which sounds like metal rubbing against metal, came back. In the beginning, the sound would happen first thing in the morning, after I haven't driven for 12 hours. Now, the sound can be sometimes heard even after the car have been parked for an hour. I fully respect the opinion of the service technician, who was unable to find the source of the problem, but I will not accept that the squeaking sound is a normal sound of the vehicle, and I want the issue to be resolved. I purchased the vehicle with 4 miles on it and currently has ~4000 miles on it. I have attached the first correspondence between me and Toyota headquarters in which I detail the the issue to them. I mention that the squeaking sound is coming from the front, but after my meeting with the service technician, I was let know that the squeaking sound could be coming from the back as well. I have been to the service technician 3 times so far without an solution privileged. After I come back from the dealer, the squeaking sound comes back after 3 days. The technician always tells us that the squeaking is because of moisture and break dust, but I do not understand why my 2016 Toyota 4runner, which was purchased in the beginning 2017, brand new from the same dealer and same sales person, does not have this issue. The 2019 4runner has been garage stored since the day it was purchased.
