| Description of the problem | As i was driving in city traffic, i noticed a grinding noise coming from the rear as i applied the brakes. It became worse as i continued to drive and brake, so i parked the car as soon as i could. I brought it into the dealer. They said the rear brake pads were completely worn away. They said i needed new rear brake pads and rotors, because the rotors had become too damaged to use. I had the hyundai service department replace the rear brake pads and rotors. There was no indication (i. E. A typical "squeal") that would have alerted me to wear on my brake pads. They were simply gone. I have serious concerns about this incident, as brake failure could have occurred had i not stopped driving and gotten my car to the service department as soon as possible. 38,000 miles is far too early for rear brake pads to be completely worn away. I do not know of any other vehicle where the rear brake pads would have completely worn away at such low mileage. I suspect a manufacturing defect has led to premature rear brake wear. This could have led to a serious accident. |
