Many more complaints of premature rear brakes failure are noted online for model years 2009, 2010. Brakes get extremely hot and fuel economy suffer greatly when this failure occurs.

I own a 2009 Hyundai Sonata. While operating I noticed a significant decrease in speed, coasting, fuel economy, and braking distance. Upon parking my car I smelled burning brakes. As I walked past the driver rear tire I could feel the heat radiating from the tire. I didn't dare touch the rim for fear it would burn me. Diagnosis revealed a seized rear driver brake caliper piston. This caused ruined the rear brakes and put undue stress on the front brakes. I had to replace the entire braking system as they had all become a safety hazard. I purchased an extended warranty which covered the rear caliper replacement but nothing else. Burning through brakes is a serious safety hazard. I haven't notified the manufacture of the failure. The failure mileage was 73,000.

I have owned this car since July 2014. I purchased the car with 54k miles. I currently have 107k miles and it's October 2016. I have had to replace my brakes 4 times, specifically because the rear brake calipers fail causing brakes to lock while driving producing significant heat and damage to the brake components. The problem also cause a significant loss of fuel economy. It appears this is a common problem on this vehicle and a recall has been put in place starting in model year 2011. The recall needs to be extended to include 2009 model year vehicles.

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 NHTSA has not investigated this major safety issue with braking systems in these cars.

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

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.

In February of 2015, less than 2 months after I purchased this vehicle used, I noticed the left rear tire was screeching when in motion like a belt in the engine would. I took it to a Hyundai dealership where they made me aware that the caliper had locked up and needed to be completely replaced & repaired along with a brand new rotor. I figured this was just a one time issue, until just this month (February of 2016) less than a year after repairing the caliper and brake system in the left rear tire, a strong burning smell was appearing periodically from the right rear tire after any drive. Took the car to the same Hyundai dealership who made me aware that the caliper was now locked up in the right rear tire and needed to be completely replaced and repaired. In both circumstances I was told that the vehicle was absolutely unsafe to drive off their lot and had to get a rental car to leave the car for repairs. I did my research. . . Apparently this same make/model/year has given lots of people the same issues. . But no recall has been made. This is incredibly dangerous and in both circumstances I was driving the car with my car seat aged toddler in the back seat. Please help me get to the bottom of this!!.

The car has had four rear caliper failures. These caliper failures have also consumed three sets of rear brake pads and two sets of rear rotors. The failure appears to be an excessive wear/slow to release condition that creates an overheating of the brake system, which has symptoms of a burning smell from the brakes and the rim of each wheel being far too hot to touch. Once we noticed the most recent failure, we noticed that the burning smell can start within about 1/2 mile drive.

My 2009 Hyundai Sonata with about 46k miles had brakes begin screeching with a metal-on-metal sound when braking. In fact, the sound continued when accelerating after completing a stop. On Friday 12/26/14, the car repair shop replaced the pads and rotors. The next day, the brakes were quiet but overheated to such an extreme that there was a strong burning smell and the wheel could not be touched for fear of burning your hand. Returning to the car repair shop, one of the new rotors was completely black from the extreme heat. The pads, rotor, and calipers required completely replacing - even the new ones just purchased. This is a safety issue that Hyundai needs to take responsibility for, issue recalls, and pay for my repairs.

I have owned this car for the past 50000 miles and have replaced the left rear caliper 4 times, right rear caliper 2 times. The rear calipers have a problem of sticking cause the rear brake pads to prematurely wear out. It appears that the protective rubber boot will pinch on the caliper and prevent it from releasing, Hyundai states this is normal. I have gone through also 4 sets of pads in the rear, and none in the front. As usual the car dealer admits to nothing, and will do nothing to help.

On July 1, 2014 the rear caliper on the driver's side of my car had seized, stripping the brakes to metal on metal. On August 30, 2014, the rear caliper on the passenger side of the car followed suit. Less than one year later I have replaced each of the rear calipers once again. I had the rear driver's side repaired on may 15, 2015, and the rear passenger side on June 9, 2015. I bought the car with just over 53,000 miles on it in 2013. Today, it has 101,000 miles on it and I have replaced four calipers, three rotors and five sets of brake pads. Each time my calipers failed I was placed in danger of total brake failure and fire, unknowingly. The mechanics who worked on my car have individually theorized that an engineering failure is the cause of this issue. Last week I contacted Hyundai for financial reimbursement for the repairs. The company stated that they could not reimburse me since the parts were not replaced with Hyundai factory parts, or repaired by a Hyundai certified dealership. I am aware that there was a class action lawsuit against Hyundai based on this issue in the state of new york. I have also read, and heard about many other people having this exact problem (rear caliper problem) in their Hyundai Sonatas, built between the years 2006-2010.

In January, when driving our 2009 Hyundai Sonata, the rear right brakes made noise and were causing noise and excessive heat to come from brake area, where the wheel was too hot to touch and a smell of hot rubber could be made. When taken into the dealer for repair, the technician stated "found the rear brakes down to metal on metal. Causing the concern. Technician replaced the rear brake pads and right rear rotor. " seven months later in August, the same noise, smell and excessive heat happened again. Per the dealer "verifed customer concern, technician replaced the right rear brake caliper as needed. Installed replacement pads,. . . " we were fortunate not to be in any accident with these poor brakes. The dealer made us pay for both sets of repairs. This is a manufacturer defect, and should be a no charge repair.

I had my car towed to the dealership in January after my brakes failed on the way to work. By putting the brake pedal all the way to the floor I was able to stop the car. The dealership told me it was the right rear caliper that had seized. They repaired that caliper, but I expressed my concern for the left rear caliper being damaged and was told that it was "fine. " well a few months later, my left rear caliper has seized and I had it towed to the dealership. They tell me that it is no longer under warranty. I told them that this is a known issue and that I expressed my concern about the left rear caliper in January. They tell me that it is up to Hyundai to decide whether it will be covered or not. This is ridiculous! peoples' lives are at risk!.

The contact owns a 2009 Hyundai Sonata. The contact stated that the brakes required excessive force in order to stop the vehicle. The vehicle was taken to an authorized dealer for diagnosis where the technician stated that the rusted brake caliper pin had seized. The rear brakes were replaced and the brake pin was lubricated. The manufacturer was notified of the problem. The approximate failure mileage was 55,000.

The rear calipers mounting bracket is holding the brakes way to tightly to the rotors so they are constintly 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 becuase the hot friction completly ruined the brakes. My wife is pregnant and I do not feel safe knowing my brakes might burn out at some point and fail.

Rear brake calipers are locking up causing premature excessive wear of the rear brakes. This is undetectable in the drivability of the car until the break pads are worn so low that they make noise.

Heard squealing and howling from the rear driver side. Took to dealership and was told that the brakes hung up and I needed to replace brakes and rotor ($189. 00). I was told that this is a maintenance issue and nothing was covered under warranty. I purchased the items and when they were going to be replaced we discovered the dust boot was pulled out of the caliper (which would have been covered under warranty) I contacted the dealer and was told that every 7000 miles the calipers would need rebuilt. I've been driving and grew up around garages and never heard of such a thing!.

Heard noise from brakes and thought it was front pads. Changed front pads but it did not solve problem. Took back tires off to check brakes and much to my surprise there was hardly any pads left. Changed pads and that stopped the noise only to have to bring my car in for service do to the fact that the calipers were not releasing. They kept the car for 2 days and said that calipers were bad. They had to put new brakes on(mine were only on a week) turn the rotors and said my brake fluid was contaminated. 10 yr 100000 mile warranty plus bought extended warranty and I still had to pay for something they call normal wear. Nothing normal about that!also wanted to drain old brake fluid and charge 129. 99 for something they had to do when they put new calipers on any way by bleeding the lines. Then to charge 110. 00 to turn the rotors. I argued and everyone I talked to said this is guide lines we have to follow. I cant believe there is not a recall on this . I am not the only one that has complained about back brakes causing problems on Sonatas. They do not cover parts from normal wear if calipers didnt malfunction I wouldnt have had to have anything done to my car. They deny,deny,deny until someone gets killed. Could be another Toyota ordeal!.

I had had my rear brakes and rotars replaces in February 2012 at around 60k miles. In October 2012 again my car felt like it was dragging and I heard the tell tale squealing of the brakes so I took it back to the repair shop to be told my rear brakes and rotars again were worn out and chewed through, and no that my calipers had seized and I would need to pay yet again to have this issue repaired. The mechanic made a comment that the only time he'd ever seen this before was from young people doing "power slides" on their cars, something I would never do (I am 28 years old). Upon research I find this is a well documented problem when searching online for break problems with this car for model years 2006-2010, enough that there is even a class action lawsuit in new york. Hyundai needs to recall and repair these vehicles as well as reimburse for the expense of fixing these up until they issue the recall.

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.

Right rear brake makes pulsating rattle sound. Seems to happen more after several miles of driving in warm, dry weather. Technicians can't find permanent cure but it did go away for awhile after the rotor was resurfaced. However, the noise has returned. This is the same wheel on which several thousand miles ago the caliper seized causing me to have to replace the entire brake on that wheel. The rattling sound has been going on for a long time, and the mileage I entered for this complaint is a sheer guess.

In regards to my vehicles rear disc brakes. From my experience and education it is very unusual for your rear brake pads to wear out before the front do. Do to weight and inertial pushing harder on the front brakes ( this vehicle is much more heavier in the front than the back). My rear pads wore out before and from some research in forums on my model car others have had same experience. I believe there is a defect here and it might involve the proportioning valve sending too much pressure to the rear calipers in comparison to the front calipers. Might of be an adjustment in the valve that is causing issue. I would like an investigation into issue . I can provide assistance if needed in regards to vehicle as subject for testing. 2009 Hyundai Sonata GLS 4-cyl automatic trans ,disc pads front and back.

Rear brakes are worn out at 19,7000 miles the calipers are worn out and my front brakes are perfect. . Front brakes usually wear out before rear brakes what is going on. . . This should never happen giving us low gas mileage these faulty calipers Hyundai should pay this could result in a crash due to a faulty brake system.

The right rear brake pad was worn down paper thin while the other rear pads were only 30% worn. Upon further inspection, I found the pad was stuck to the pad mount/anchor. It was so stuck I had to remove the whole caliper and hammer the old pad out. When I explained my situation to the dealer, they said it was a common problem and that I should bring my car in every 15000 miles to inspect and lube my brakes. I explained to them that the owner's manual says nothing about disassembling and re-lubing my brakes every 15000 miles. I also commented on how unrealistic it is for every Sonata to need a brake lube every 15000 miles. The service representative blew off my concerns. I'm sure the dealership would love to sell everyone a brake lube every 15000 miles, but that's ridiculous, especially for a safety item such as brakes. This safety issue needs to be addressed.

Rear brakes: rubbing, grinding, premature wear and reduced breaking effectiveness. Replacement of rear rotors and pads were required replacement to pass safety inspection. Dealer informed me that the calipers were not siezed or sticking but that dried out lubrication on slides, pins, shims was the cause of the wear.

My 2009 Sonata has 44000 miles and the rear brakes are grinding. They need to be replaced but the front brakes look brand new. I have been working on cars for over 40 years and have never seen or heard of anything like this before. Rear brakes just don't wear out faster than the front ones. I have an appointment tommorow at the dealer but they told me it is not a covered item but a wear item. There is a problem with the calipers sticking and causing the brakes to wear out. Routine maintainance would have taken care of the problem. What routine are they talking about? it is not on the recommended list at any mileage in my owners manual. Thanks god it is only something like brakes and not something important like the radio going out. Sarcasm is how I deal with stress. Rjh.

Brake caliper failure. Right rear brake caliper locked up when slowing. An independent mechanic inspected the vehicle and determined that all of the brake calipers had significant and premature corrosion which is causing the brakes to stick and the vehicle is not safe to drive. He also suggested that the car be taken to the dealer for service because based on his research the brakes on this model vehicle were likely defective from the factory and he wouldn't be able to fix them properly using factory or aftermarket replacement parts. He speculated that since the dealers have been inundated with this problem, they may have some installation tricks using the defective Hyundai calipers. The independent mechanic then spoke with a Hyundai dealer service rep and they stated that "this is common in areas where road salt is used, even for Sonatas with lower miles and the best they could do was to clean the calipers. " I'm bringing the Sonata to the dealer on Saturday, August 27 for repair but I don't feel safe in this vehicle based on the discussion with the dealer.

I own a 2009 Hyundai Sonata limited edition. I bought it on April 8, 2010 and it had 21k at the time of purchase. On July 17, 2011, (now at 47k miles) I noticed a squealing noise coming from the tires as they went around. This noise got progressively worse over the next 3 days and I brought it in to the dealership where I purchased it. (I also purchased a great 7yr warranty which covers basically anything except for routine maintenance items. ) I dropped the car off on the evening of July 21, 2011 and the next day the dealership called me to inform me what was wrong with my car. They said the caliper slides were hanging up and it had caused all my brakes and rotors to need to be replaced. They offered to fix "my problem" for $520. I asked how this could possible be my fault, I've owned several cars and I've never once heard of lubing the caliper slides. They said that this was routine maintenance and would not be covered under my warranty, even though my warranty specifically states that it covers faulty calipers. . Read more...

Rear brakes failed on 2009 Hyundai Sonata. . . Also had lot of noise, grinding, was able to stop car because front brakes did work. Took to garage to have pads/rotors checked told it was dealer issue car too knew/low miles. Still replaced one rotor and pad as totally gone. One tire would not rotate properly. Went to dealer - dealer finally admitted caliper defective on rear brakes - told car not driveable parts not in stock - drive car home - will call when parts in. Brakes very, very hot. Rear brake turning on and off at will.

Premature rear brake wear at 22k on oct 2010 caused failed safety inspection at dealer. Inside rear brake pads rubbing. Replaced pads and cleaned sliders myself and passed inspection. Rear brake pads hung again on Mar 2011 causing hot wheel. I replaced the sliders with new and filed the metal tabs of pads and used anti-sieze compound to prevent sticking. If this doesn't work I'll contact Hyundai for caliper failure.

The contact owns a 2009 Hyundai Sonata. The contact stated that when the vehicle was taken to the local mechanic for routine maintenance he stated that the passenger rear calipers were stuck and unable to rotate due to corrosion causing the brake pad guide to fail. The mechanic replaced the brake pad guide. The manufacturer filed report 4243771. The failure mileage was 20,442 and the current mileage was 20,618. Updated 3/14/11 updated 04/22/11.

2009 Hyundai Sonata rear driver side brake noise due to the "sliders" on the caliper. I took my car to the dealer (car has 35,000) to pin point noise. They told me there is uneven wear on rear break pads and that the sliders are sticking causing the pads to stay compressed to rotor. They offered to "lube" them for me and replace pads for over $200. 00. This is not normal wear and tear.

I have a 2009 Hyundai Sonata that started making noises when braking at about 18000 miles. The first time I was told it was the rotors and I paid to have those turned(?). The noise went away for a couple of weeks. The next time I was told it was debris on the brake pads. (really?) the noise again went away for a week or two. Next I was told the calipers needed to be adjusted. Again, a couple of weeks till I heard the noise again. The next repair was new front pads that my dealership got approved from Hyundai warranty. Again no noise for a couple of weeks. Now, at 36000 miles I need rear brakes. In between the times my car was repaired, I also took it to the dealership at least 6 times when they either could not hear a noise or could not find the noise. I live in florida, no salt on the roads. Most of my miles are highway miles. I have never had a car need rear brakes before 100,000 miles, even in connecticut. I have looked up Hyundai brake problems online and found numerous complaints about the brakes. This should be made a safety issue, not a maintenance issue.

I have a 2009 Hyundai Sonata with 45000 miles on it. The first time I replaced the pads in the rear at 10,000 miles . I have replaced the rear brake pads an additional 3 times and the front pads only once. I have been a mechanic and automotive technology instructor for over 45 years an never had a vehicle wear out rear brakes faster than the front ones without something major wrong with the system. I have checked the calipers and they are not draging the pads against the rotors. The first time I reported the problem to the service manager he said this was normal, I don't think so!.
