| Description of the problem | i heard high pitched noise from rear while driving 2007 sonata gls. I found that the rear wheels were extremely hot. I was afraid the tires will catch fire due to the heat. I took it to the dealer in southfield michigan. The manager said that it would cost me $300 to replace rear pads and they were not covered under warranty. Rear brake pads essentially were 95% worn out. Front brake pads were minimally worn during this time period and were ok. I got them replaced at "napa complete car care center" for $176 in oct 19, 2009 when it had 17,513 miles on it. At 40,042 miles while driving from detroit to milwaukee, i heard dreadful grinding noise. At "car-x auto service" in milwaukee they found the same problem with rear pads while front pads were ok. One rear pad was almost bare and others were more than 95% gone. I spent another $350 and this time the rotors also have to be replaced. There is definitely a design flaw and it is a safety issue due to heat which can cause tire fire. It seems the rear pads stop moving freely after certain pad wear. It could be too much hydraulic oil pressure in the rear brake lines or there is some defects due to abs system. Hyundai must own this problem and fix this issue for good. Environment al (salt, water etc) effect is the same for both front and rear brakes. Front brakes do not need any adjustment or lubrication and they are ok. Why would only rear brakes need cleaning and lubrication at every 5000 miles as suggested by the dealer? In my driving for 40 years i have never seen this issue in any of the other vehicles i drove. On checking internet discussion boards i found that this issue is common and hyundai is not doing anything. This is not fair at all while consumers are holding the bag with perpetual expensive repairs and fear of being stranded and tire catching fire. |
