2021 Q7 brake squeal

[Mik23]

I’ve had my 2021 Q7 for almost 2 years now and the brake squeal has been terrible on it. I discovered it about a year into ownership when valet was bringing my car. I thought this possibly couldn’t be my Q7 which had less than 7000 miles on it. The windows do an amazing job of blocking out the noise so I had never noticed it.

During my first 10k service, DTLA audi service said the noise is because there was tire shine applied on the tires that oversprayed onto the rotors…i’ve had 4-5 different cars all washed at the same place for years without any issues but I was in a rush and just took the car back.

I’ve been trying to do some hard braking to see if it helps but the noise has gotten worse and squeals everytime I come to a stop. Backing out of the garage in the morning is the most embarassing part.

I know the 2017-2019 had actual service bulletins issued for the brake squeal but anyone else who has a 2021+ that is dealing with brake squeal as well? I plan on asking the dealer during my next service to actually identify which brake is the issue and try and find a resolution because it’s honestly embarrassing to have a 65k suv thats less than 2 years old sounding like a train each time it comes to a stop. If it was a carbon ceramic 911 brake, i’d get it but this is a very standard SUV.

Looking forward to hearing any advice/responses. Thanks!

My 2020 has some brake noise as well. I’m interested to hear what you learn.

It came back from service and they tried to do some fix but it still has the issue so I am taking it back in. Audi did acknowledge that this is a warranty issue so I will see what comes out of the next visit. The noise has become worse unfortunately.

On my 2017 I had brake squicking specially when reversing and it was cold night before. The fix was to add retaining clip to the pads. Out of factory the brake pads/calipers come with one retaining clip but there is space for two, adding second clip made the pads mate evenly. There was a write up about it some ware that I seen few years back, but your issue might be something else..

Same here.My son was driving my '21 Q7, heard a squeal and then experienced total brake failure resulting in a major accident. Anyone else experience a similar situation? Appreciate any advise, etc. Cheers!
