Brake Grinding Noise problems of the 2009 Hyundai Sonata

Rear brake calipers have seized at least 7 times, causing me to need to replace them. I'm at 115,000 miles and have had the left one seize, destroying the rotor and pad 4 times, and the right one seize 3 times (once recurring within 15,000 miles of replacement). The car has been repaired at different shops, but the problem keeps recurring. First time occurred shortly after 30,000 miles. Occurs every 1-2 years since then. Most recent occurrence is now (car is being repaired this morning, left rear caliper/rotor/pad). Noticed massive shimmying this time. Previous times have been noticed from: grinding noise, car won't accelerate over 10 mph (locked in engaged brake mode that time), and severe bucking while being driven.

The contact owns a 2009 Hyundai Sonata. After the vehicle was parked, an abnormal odor was present outside the rear driver side of the vehicle. The contact also stated that a grinding noise was heard while the brake pedal was depressed. The vehicle was taken to a dealer where it was diagnosed that the caliper failed and needed to be replaced. The vehicle was repaired, but the failure recurred after 7,000 miles. The manufacturer was notified of the failure. The failure mileage was approximately 60,000. The VIN was not available.

The contact owns a 2009 Hyundai Sonata. While driving 10 mph, the brakes made a grinding noise. The failure was similar to the failure listed in NHTSA campaign number: 13v113000 (exterior lighting, service brakes, hydraulic). While changing gears, the shift seized and the esc warning light illuminated. The vehicle was not diagnosed nor repaired. The manufacturer was not notified. The VIN was invalid. The failure mileage was 20,000.

In April 2013 my rear brakes had to be replaced for inspection. The right rear side was down to nothing, it was rubbing bare metal to bare metal, brakes again rotors. The left side was also more worn than it should have been, but not as bad as the right side. In July 2013 the same issue happened again. The right rear side was rubbing metal to metal, brakes against rotor. The left side was fine. The brakes parts (caliper) were working appropriately. In October 2013 the right rear brakes began squealing and approximately 2 weeks after the squealing began it started making the same grinding noise as it did the previous times and the brakes had to be replaced again. This time, the caliper also had to be replaced. My rear brakes have had to be replaced three times in 8 months.

I purchased my 2009 Sonata in March of 2012 at the local Hyundai dealership, with about 44k on it. Everything was checked off and confirmed as in good working order. A history report showed the brakes being replaced last at 41k miles. I took my car in for its 60k checkup and have been told the rear brakes are shot, and everything needs to be replaced. . . Pads, calipers, rotors, etc. It hadn't made a grinding noise or anything at that point, so I decided to take it to a certified mechanic I usually go to. He confirmed everything and said all told the repair is going to cost me roughly $800!!! he also told me it was a big issue they see only on Hyundai's, and that there is no way the rear brakes should ever go before the front brakes need to be replaced because there is so much force that is needed to brake the front of the car compared to the rear. So did research and find out that this is a huge problem with these vehicles. I am not looking forward to replacing my entire rear brake system every 15-20k miles. I will be filing a formal complain with Hyundai as well. . . My hope is if they want to keep their customers, they will do something about this all too common issue!.

I have a 2009 Hyundai Sonata and a grinding noise started coming from the back passenger side while I was driving the car. I took it to the Hyundai dealer and they said my brakes and rotors needed to be replaced. I purchased the car used, a little over a year ago, from the dealer with about 13,000 miles. It now has 37,000 miles, the majority being highway miles. I took my car to another car repair shop because the price I was quoted from the dealer seemed unreasonably high. The place I took my car to told me that while inspecting the car they noticed that the passenger side caliber was stuck and that they were able to unstick it. The mechanic said he would need to replace the passenger side rotor and the brake pads. He said I should think about replacing the calipers. I asked why they would go bad this soon. He said it could be a defect, that there has been a defect reported with the Hyundai santa fe calipers. I asked him if this is something that should be covered under my car warranty. He said I should check with the dealer. From everything I've read on the internet the calipers should not go bad this soon. If they do, they cause the very problems I am having. I contacted the dealer and told him what the other mechanic found in regard to the caliper. He told me there was nothing wrong with the caliper when they looked at it. The funny thing is that the price the dealer quoted me to repair just my brakes and rotors is the same price the other mecanic quoted me to repair the rotor, brakes and calipers. I am having just the brakes and rotors done at this time since according to the dealer there is no problem with the calipers. If they are not telling me the truth, I will be having this brake problem again.

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.

The contact owns a 2009 Hyundai Sonata. The contact stated that the brakes would emit a grinding noise whenever they were applied. The vehicle was taken to an authorized dealer on several occasions where the brakes and calipers were replaced; however, the failure continued to occur. The manufacturer was made aware of the failure, but offered no assistance. The failure mileage was 40,000.

The contact owns a 2009 Hyundai Sonata. While driving 35 mph there was a squeaking and grinding noise in the brakes. The pin that controls the brake pads and rotors became worn. The pin also controlled the movement in the brake calipers and when it does not move it deteriorates the calipers and rotors. The vehicle was taken to the dealer who stated that she had to replace the brakes at her expense since they were not covered under the warranty or recall. The manufacturer was not contacted. The VIN was unavailable. The failure and current mileages were 28,000.

Returned car to dealer 16 months after purchase due to grinding noise from wheels. Brake calipers had locked up, destroying pads and scoring the rotors. Brakes serviced again in 2012 and 2013 for worn pads and grinding noise. Brakes failed again in June 2014 requiring new pads and rotors, front and rear. Returned car to dealer due to a burning smell in December 2014. Found right rear caliper had seized. Replaced caliper and pad. Again burning smell in January 2015. Dealer found left rear caliper had seized. Replaced caliper, pads, and rotor. Contacted Hyundai motor America who states this is normal. Also state that design defects are not covered under Hyundai warranty.
