One problem related to brake drum has been reported for the 1999 Hyundai Sonata. The most recently reported issues are listed below.
The brakes on this vehicle have squealed since the first few months after I bought the car. I had learned to live with it. I keep my windows up and radio on so I can't hear them squeal. Lately, though, they have become louder and more constant. I haven't gone to the dealer with a new complaint, because they assured the last 2 times I complained that there was nothing wrong and "that's just Hyundai brakes. They'll stop you, but they are loud!" whatever, surely there is something that can be done. I have friends with other types of Hyundai's and their brakes don't do this. Mr.
