2021silverado Brakes Squealing while going slow through drive through

[Truston Gunter]

So I have a 2020 Sierra HD with this same problem. According to the dealership, this is NOT covered under the bumper to bumper warranty and is ONLY covered for 7,500 miles regardless of any service bulletins.  . Well my truck has 21,908 miles and guess its my fault for not taking it in sooner thinking I had 3 years / 36,000 miles for any "manufacture defects" to be corrected. Very disappointed however, I would like someone to verify this is true and not just the dealership being...... how can I say it nicely...... "ill-informed"....... Hate feeling like this dealership is trying to not do the work for whatever the reason.

I had the squeal and the dealer I purchased from only changed the fronts. Squeal came back in a few months. I then took it to a dealer in Florida (Estero Bay Chevrolet) and they replaced all 4. The squeal is gone except for an occasional minor sweal in the morning and not every day. A good dealer will support you.

I am on my second set of dealer-replaced brakes and they are squealing again. They were only down to 97-98% before they started AGAIN. So frustrating, under warranty, getting replacements and it is the same problem since I bought the truck 3 years ago!

Think the dealer may have been dishonest with you.  I had my pads replaced free under the bumper to bumper around 8000 miles.  There is a tsb on it.  They actually replaced the fronts first, the back pads took about 3-4 weeks longer to come in.  I have my truck going in tomorrow, and they will be looking at replacing the brakes again for squealing again(ordering new pads), while it is there for a recall and oil change.  Truck has just shy of 15,000 miles on it now.  My truck is a 2020, bought in August of 2020.

Since this post I have contacted the dealership from which I purchased the vehicle from, ( Cavendar Auto Country in Weimar, TX ) which is 160 miles away. At first they told me that the info I gave have them didn't seem right and they would look into it. They also confirmed the service bulletin. The local dealer I use is about 30 miles away (aransas autoplex in Aransas Pass, TX), they explain to me that GM would deny their claim because it is over the 7500 miles threshold . Later on Cavendar called me back after speaking with their manager and informed me of the same. I personally believe the size of the dealership in this case matters. Both of these dealers are "small" versus a national chain who would more than likely absorb any loses if GM did deny a warranty claim after the work was done. Anyways, that's all the info I have right now, I also found a fixed to the squeaking, just gotta keep it above 50 mph in the drive thru and voilà no squeaking!!!!!
