Not sure if this requires investigation by NHTSA so I am reporting it and will let you decide. 2020 Audi Q-3. Purchased Certified Pre-Owned in April 2023 with 13,000 miles on it. Found that at highway speed when you apply brakes the pedal pulsates and shudders. I now have 17,900 miles on it and the pulsation is getting worse. To my regret we did not take a very long test ride when buying. I have not lost control or had any accident, but I Googled the problem and found that this is a common complaint with many Audi models. Brought car back to dealer who states that I need to replace front disc pads and rotors as well as rear brake pads. I feel that this is not normal with such low miles. I am not sure if this needs an investigation by NHTSA but again, if you do an online search it is a problem with many Audi models. I have been advised that this problem could lead to loss of control of the vehicle. Also, the dealer and Audi USA refuse to do the repair under the warranty saying that brakes are "a wear item".

As in past instance related to the diesel engine fuel consumption case, Audi is hiding the fact that their brake rotors for the Q3 2020 model have a manufacturing defect. The rotors are produced warped from the factory and it may cause various breaking issues as the mileage increases, starting with noises, steering wheel and car vibrations to possible brake failure. Audi does not want to acknowledge the issue so they do not have to repair these cars permanently or declare them undrivable and, as their mileage increases to provide warranty for defective parts beyond their original warranty term. They also do not want to make this an issue which requires a mandatory recall for tens of thousands of vehicles preferring to blame it on various other factors related to the vehicle being driven to a lesser extent and rust accumulating on the rotors. ​ in fact they recognized this as a known issue and replaced the 4 rotors after 4000 miles, and when the problem reappeared after another 2500 miles the denials and blaming on the way the car is being used (less than average mileage) started. Their refused to fix the problem properly in the hope that after the warranty expires they will be able to charge for repairs. In fact, being concerned by the safety issues related to defective parts, I offered to pay for the replacement of those parts and I got from them a quote for the costs. They refused to fix the problem because that would mean an acknowledgement of the existence of the problem (needing to replace 4 rotors after 4000 miles and 2 rear rotors after another 2500 miles). They also are blaming the customer for heaving braking which causes the issue when in fact the car is driven lightly and only when allowed over the 60 miles/hour limit. Issue should be addressed with a permanent fix.

I bought my 2020 Audi Q# premium plus S line as a cpo from Audi of natick in natick mass 0N 9/26/2020. It had approximately 4500 miles on it when I took delivery of it. The car makes an unusual noise from the rear brakes whenever I use them. This is not normal and usually only happens when brake pads are worn to the point of having little to no braking material left. I mentioned this to the dealer before I took delivery and was told it was normal. Ive been driving for over 45 years and know that this is anything but normal. I drove a number of 2020 Q3's and they all did it. I also drove one 2019 Q3 and it did not do it. I know that this is a typical complaint among the owners of these vehicles and want Audi to rectify it.
