2021 Chevrolet Silverado 2500: grinding or squealing brakes

Filed Apr 24, 2023 · Electrical, Transmission · NC

2021, Chevrolet Silverado 2500 HD, Crew-Cab, 6.6L Gas Engine. At @ 25k miles, the "Service 4WD" light came on dash. It later started a grinding noise/sound within the front axle transfer case. Was told they had a problem with moisture intrusion into the transfer case and it would cause corrosion to sensor. Truck was taken to dealership and in shop for @ 1 week or so. After repair was completed, less than 3k miles later, it happened again. Same problem ("Service 4WD"), same noises, same diagnoses. Truck was taken back to the dealership. This time, repairs were more extensive and the wiring harness was replaced. I was traveling with work yesterday (34,458 miles on truck now) and the "Service 4WD" light came on again. I've contacted the dealership to schedule a time at the end of week or early Saturday to take the truck back again. While reviewing other complaints, I noticed a similar problem where the customer indicated the "Service Tow System" light was coming on. It too was allegedly caused from moisture intrusion. I'm currently over 3 hours from home through the end of the week. I'm hoping the truck will make it home without creating a catastrophe on the Interstate between here and there.

The brakes have squealed since the day we purchased it new. The noise is usually at low speed, under 10 MPH. The dealer has told me that they could replace the pads but I would have to cover the cost.

Very bad brake squeal while applying brakes at 10pm or less, coming to a stop. This started to happen when the vehicle had approximately 5,500 miles.

Non stopbbreak noise. No matter what you do, what is or isn't added, how clean they are, they constantly squeak and loud! Dealers won't help. Tell you to get on the brakes hard. That helps for a few minutes! Over 50k fix the brakes!!!

Brakes: the brakes do not stop the vehicle without excessive pressure to the pedal. Especially carrying a trailer with the exhaust brake & trailer brakes in effect. Takes excessive distance for vehicle to stop. Pedal must be pressed 3/4 to the floor for it to start to apply brakes. It is extremely difficult to stop this vehicle at any speed over 45mph. Have not taken to dealer, was expecting a recall but none until now. Steering: when I turn the steering wheel at low speeds such as backing into a parking spot, there’s a loud squealing noise coming from the engine bay.
