The Audi S4 is one of the top premium models in the market. With a price tag like that, people expect it to be the best. That is why this buyer on Reddit was not too happy when his 2016 Audi S4 started squealing.
Based on what he reported, the squealing sound does not happen all the time but it does happen. The surprising part is that he is not the only one experiencing this kind of problem with an Audi.
A few other Audi owners did come forward to say that they too had experienced the squealing issue. Some people concluded that the squealing happens when the brake is cold but other owners seem to disagree.
It can be pretty frustrating especially since this is coming from an Audi. Have you experience anything like this on your Audi before. Check out what the other Audi owners are saying here.
