| Description of the problem | 2007 sonata w/ 34000 highway miles. Car was making a high pitched sound from the back left, and the drivers side back wheel was becoming very hot while driving. The dealer, napleton hyundai basically said everything is fine, i just need to pay for a whole new set of back brakes. Knowing the heat was from the pads not releasing, i refused the work and investigated myself. Like other complaints here, i found that the pads are too tight in the calipers, and also are corroded. The heat issue only makes them fit tighter. The pad guides needed to be lightly filed and coated with anti-seize to fit and slide properly. I googled this and scanned the hyundai forums, and the internet is littered with sonatas and other hyundais with the exact same problem. Hyundai will not address the issue, preferring to charge customers for new brakes and regular brake "lube" service. Hyundai consumer affairs also did absolutely nothing about this. This is a safety issue and a design flaw. Sooner or later this problem will cause an overheated wheel/tire to fail, or a wheel to lock up under slippery roads, and someone will be out more than just repair money. |
