| Description of the problem | The rear brake calipers appear to be defective in that a high percentage seem to fail. This is the second caliper that has required repair/replacement, which necessarily also requires replacement of brake pads and rotors. It appears that the calipers stick in the extended position causing (in the best case) the rapid wear of the rotors and calipers, and (in the worst case) a heat build up, and a failure of the brakes. Internet blogs indicate that this is not just a problem with my vehicle but is systemic with hyundai sonatas, and particularly 2009 and later. I will note that hyundai had a brake recall regarding calipers for sonatas between 2011 and 2014, but that it did not extend to the 2009 sonatas. |
