I have had the same issue with a 2019 LT. started at around 4500 miles. loud squeaks when lightly applying brakes at slow speeds. generally when brakes are cold. took it to the dealer right away and got the same response as others here (rust build up). not sure how the rust builds that fast in just a couple hours? Dealer didn't do anything at that time. Took it back a 2nd time some weeks later to make another attempt at fixing this. dealer was unable to replicate, or so they said. but they did lube calibers. this didn't help at all. I took the truck back a 3rd time for the brake recalls issued by GM. as part of that recall, they replaced brake pads. Surprise, the squeak under these conditions stopped!!! 3 days later, brakes are now making a fog horn type noise, but not when applying brakes. they do that when beginning to roll away from a stop. again, this happens mostly when cold, and at speeds under 5mph. I had hoped this would disappear on its own, but it got worse. I took the truck back a 4th time to the dealer for this, was given the same indication as the first couple times that there was rust build up causing this and that I needed to drive it more. It made the noise that same day when leaving the dealer. this continued to get worse, to the point that I could drive it any distance, and stop for about 2 minutes and then replicate it. so I opened a case with Chevrolet this time for the issue, and they arranged for a 5th appointment to take the truck to the dealer. Dealer had the truck for 15 days. I was in contact with the Chevrolet SR. agent on my case and requested that they help me get out of this truck and into something different, as I have lost complete faith in this truck. I buy a truck and keep it for 10-20 years, and so this one was expected to do the same, but I have no faith that it will. got it back about a week ago, and they said they replaced the rear brake calipers, and adjusted return springs/clips on the front brakes. Surprise again! brakes were completely silent no matter the condition. Drove the truck for 4 days with absolutely no noise at all. I had hopes this would fix it. on day 5 and after about 100 miles, the brake squeal is back. fog horn noise is gone and we are back to the issue prior to that, squealing under light brake when cold and at slow speeds. I have owned this truck for almost 2 years, only have 16000 miles on it, and have had the brake noise issue for over 10K of those miles. so now I am faced with a 6th visit to the dealer for this same issue. I have no answers yet from GM on whether they can honor my request to get out of this truck. but will continue to push for that as a final solution, since it seems nothing they do will fix the brake noises.
