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.

Purchased my 2009 sonata in february 2009, by mid july I had to replace the rear brakes. I was a little surprised since the car was new and only had about 5000 miles. I was told that I was required to check the brakes every 3500 miles and it wasn't covered under warranty, not even the 5 year bumper to bumper warranty. It is now 2016 I have had to replace my rear brake calipers, pads and rotors every 6 months at a cost of over $400 every time. There is a great deal of grinding, heat and massive vibration in the rear while braking to this point. I have returned my car for both current recalls (not applicable to brakes). With so many models having the same issues, its very disappointing that hyundai will not repair their faulty engineering and the federal safety agency has not investigated this major safety issue with braking systems in these cars.

Premature wear and replacement was required due to a defect involving the brakes and calipers which may involve defective parts and/or premature corrosion. Brakes and calipers replaced twice in two year period. Rear brake calipers would periodically stick and grind causing brakes to smoke and give off burning smell. Car at times was unsafe to drive due to these problems.

The incident is similar to the federal safety agency id# 10508953 which stated there was a grinding noise after starting the car. I experienced the same malfunction but sometimes the grinding doesn't stop until the engine is turned off. It doesn't happen everytime the engine is started but I also had other problems with the ignition switch. A few times the engine started while the key was just turned to the "on" position. After hearing of all the ignition switch problems with gm vehicles, I thought this should be handled by hyundai as a recall because it is definitely an unsafe situation. I hope the federal safety agency will take action on this matter. The vehicle owners should not have to pay for defectively manufactured components no matter how old the vehicle.

I have had to replace my rear brakes and rotors twice in 5yrs. The first was in may of 2012. The vehicle had 28,000 miles. There was no warning lights my first indication was a dragging sound. I just had them replaced again april 2014 with 42.000 miles. Again no warning until the horrible grinding sound. Also many times after long trips there is a distinct burning smell. I was told by the dealer that it was my tires. Another repair company told me it was my brakes getting hot. They said that the rear brakes are constantly engaged thus burning the pads and decreasing gas millage. Other people have reported the same problem though hyundai denies it. It is a huge safety issue!!

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.

The rear calipers mounting bracket is holding the brakes way to tightly to the rotors so they are constantly being applied. The only way to prevent this from happening is to manually grind down the sides of the brakes to make them fit properly. I found this out when I changed my brakes before a long car ride (approx 4 hours). The brakes were holding the car back and throwing off my alignment. Bought vehicle with 49000 miles with new brakes. Replaced them at 68200. Currently has 69200 and I have to replace the brakes again because the hot friction completely ruined the brakes. My wife is pregnant and I do not feel safe knowing my brakes might burn out at some point and fail.
