I purchased a certified pre-owned 2020 Chevy Silverado 3500HD (6.6 Gas) November 2021. Within the next few weeks, I noticed brake squeaking that kept getting worse and the truck braking system would not stop like the 2500 I had traded in when I purchased the 3500HD. I had to adjust the trailer brake gain control up to as high as 9 or 9.5, should not have to adjust that high. I had trouble stopping at intersections and quick /emergency braking situations while pulling our trailer. This tells me the truck braking system is not working properly. Prior to leaving on a trip, I was having squeaking noise from the brakes that got louder and louder and more frequent. The dealer (Champion Chevrolet) checked the truck and brakes and told me it had the wrong brake pads and had replaced them. The first time I pulled off the interstate on my trip to Florida, the brakes began to squeak as they did before. This happened during the entire trip. Over the next few weeks after returning from my trip I had a couple of close calls trying to stop at traffic signals. My breaks would not stop me and I went into the intersection barely missing other vehicles. I am almost to the point of parking the truck until the dealer can make repairs that will fix the issues, but we use the truck to pull a trailer that is a major part on our income. I’ve had the truck back to the dealership I purchased the truck from and they keep saying it is a brake pad issue. They have changed the pads twice so far (I think), and within days the squeaking and noise starts again. Periodically I keep getting a message (service trailer brake system) on my dash display that is difficult to get the warning to stop displaying. The trailer brakes had been checked several times and I have hooked other trucks to the trailer and it works fine. So, the issue is with my truck and the braking system.
