Brake Disc Caliper problems of the 2007 Hyundai Sonata

At the tire replacement service at about 61k miles (very gentle, first owner, still had more than 2/32 tread left on the factory tires at 61k miles) I was told by the technician that the rear break pads have to be replaced. With in 2 days I took the car to aamco since there was a $35 brake pad service deal. I was told after inspection that a caliper piston is seized and so the calipers, the damaged rotors and of course the brake pads have to be replaced - preferably for booth rare wheels, in order to have similar braking characteristics. While it is common sense that the front brake pads would wear faster, the aamco folks were surprised to find the rear brake system in such a bad condition while the original front brakes were still good. Per their opinion it is mostly due to a manufacturer defect. I called Hyundai warranty immediately, they provided a case number, but I was told I was out of luck since I am just past 60k miles and also there is no recall specific to rear brakes that will address my concern. With this I thought I lost all my bragging rights about Hyundai - on their reliability and value for the money. Moreover, this is unbelievable since on a 1997 Nissan altima which I own, I still have 25% left on the rear brakes at 125k miles. Shortly later I found scores of Sonata owners who complained about this issue in the internet forums as well as NHTSA site. I also found complaints about sun visors not staying in place, hanging loosely, a hazard while driving. I have this problem too but never payed much attention to it. Currently I am not in a position to shell out over $600 dollars to get the rear brake issue fixed to be able to take myself and my family safely in the car. I hope my complaint breaches the threshold and NHTSA takes action to have Hyundai fix the issue at Hyundai's cost ASAP. Thanks for providing me this opportunity to log the complaint.

Passenger side rear brake caliper frozen causing metal on metal cantact and premature failure and replacement of rear pads and right rear rotor. Front pads were hardly worn. Car milage at 17,000 miles with normal driving conditions.

Right rear outer brake pad seized in the pad holder, grinding the rotor. Dealer repaired the brakes and charged me $ 400. 00 even though the vehicle was still under warranty and should have been repaired free of charge. The front pads were only 50% worn and they do most of the stopping. Now Hyundai dealer says that the Hyundai Sonata vehicle should have rear brakes cleaned and lubricated every 15,000 to 20,000 miles at my expense, to prevent "lock up". Hyundai does not mention this type of maintenance anywhere in it's maintenance schedule. After checking on the web, I find that this is a common safety problem among Hyundai owners who are being ripped off by Hyundai who refuses to repair this defect under warranty or recall the faulty brake calipers. I live in a rural area and mileage is 90% highway, so there is minimal usage of the brake compared to city dwellers, yet the brakes failed prematurely.

Frozen rear calipers causing brake failure and near accident. Required action - new calipers, rotors, pads.

Intermittent rear brake noise on 2007 Hyundai Sonata for over 1year. Twice inspected at dealers shop, no problem found and all disc brake pads within specs. I noticed recently at 42,000 miles that the passenger side steel rear wheel was getting extremely hot due to rear brakes overheating. My dealer stated that pass. Side rear brake pad had worn down almost completely due to "brake pad slides sticking on calipers". New set of rear brakes were installed at cost of 240. 00 . My dealer and Hyundai corporation both stated that repair work would not be covered under warranty! I feel this is a safety issue not only because of rear brake pad premature failure but the unknown effect on the rear wheel bearings due to overheating of brakes/wheel.

Defect in design or substandard metal parts in the rear brake assemblies of 2006 & later Hyundai Sonatas causing premature brake wear. I have premature brake pad wear (metal on metal) after 35,000 miles on my 2007 Sonata. This condition is reported online by many other owners with as little as 20k. Dealer will not cover under warranty. Hyundai USA will only consider reimbursement after it is repaired first and preferable by a dealer. My dealer said its a "design flaw with the pad retainer", those online report corroded caliper mounting pins as the cause. Some report they need to routinely clean and lubricate these parts to prevent the excessive wear. Because this is a brake issue, safety of all owners should be enough to issue a recall.

I have a 2007 Hyundai Sonata that has a stuck caliper for the second time in 14 months. The first time they changed both rear calipers under warranty as the car had just under 36k miles. Yesterday, at 55k miles, I discovered when having my oil changed that the rear caliper on the driver's side is stuck again. I heard a little squeaking this last week and thought I would have my breaks checked. To my surprise, mechanics at mr. Tire told me the right pad is hardly worn, but the left rear pad is almost completely gone and has affected the rotor slightly. I am afraid this will be a safety issue in the ice and have read many similar complaints on edmunds carspace and believe this should be an issue for recall.

I have a 2007 Hyundai Sonata purchased in April/may 2007, and I've always done regular maintenance at dealers only, no outside servicers. Bought car at power bowser in pittsburgh, PA (live in boston now) who did PA state inspection and 30k service there when the car was at 32k miles in 2/09. (rear brakes had been replaced already in 7/08). At the time, front brakes were measured at 60% remaining and rear 90% remaining. I did mostly highway driving, which involves little braking, since that time. Less than 7k miles and 7. 5 months (my car is now at 39k) later now my car is at mirak Hyundai in massachusetts with the front brakes measuring at 25-30% and damaged rotors, and the back brakes are at zero% on one side in the back and 70% on the other side in the back with the 70% side immobile in the caliper having worn down from 90% only because of rotor wear. In other words, one side of my rear brakes was not functioning causing the other side to wear to zero, and I was driving on 25-30% front brakes. The back rotors were destroyed and had to be replaced with the brakes. The power bowser in pittsburgh service manager told me that this is a widespread problem with the Sonatas (especially my model year) that Hyundai corporation is fully aware of (in 2 ways they either stick to the rotor or don't move, as in my case) and has not recalled or issued a bulletin on. Instead, they apparently have a "goodwill unofficial warranty" that they will fix the problem if it happens within 2 years or 24k miles of purchase. My car is a few months over 2 years old, so that did not apply to me. They knew about this problem with my model car, but I had no warning. I was driving around with one side of my back brakes not working that wore the other side to zero and was grinding metal-on-metal. I had to pay $500+ for the rear brakes and rotors. Overall, this incident was not only costly but frightening that they let me and others drive around on brakes they know to fail.

We own a 2007 Hyundai Sonata with 16,000 miles on it, barely 2 years old. The brakes had a squeal at about 15,000 miles and we couldn't put our finger on the problem. At 16,000 miles the rear wheels began grinding and I called cochran to have it fixed. They set me up with an appointment the next day. They told me my back brakes were worn and the rotors needed cut. This has to be some defect in the braking system, I've never had to replace brakes on any of my cars under 50,000 miles. They said it was not a warranty problem and charged me $225 for the repair. I think hyndai should put out a recall on these calipers hanging up on the 2007 Sonata, and reimbursed all of us that have had this problem.

During dealer inspection, rear brake on passenger side of 2007 Hyundai Sonata was found to be worn down asymmetrically - on one side completely - due to stuck brake caliper. This was at 34,000 miles.

2007 Hyundai Sonata 18,000 miles, rear driver's side complete brake failure because caliper did not release pad. There was no warning sound or light to alert me to the problem until the rotor was completely worn. Rotor and pad replaced. Service stated that brake slide needs lubrication frequently, a service that is not recommended in the owner's manual.

2007 Hyundai Sonata. 11,500 miles left rear wheel seized up while traveling on the interstate. Mechanic said: brake caliper was frozen causing the brake pads to wear prematurely causing overheating and damage to the rotor. Fortunately I did not loose control of the vehicle so there was no crash. The brakes on the other 3 wheels were fine indicating a defective part(s). Now the frustrating and unbelievable part of the issue: Hyundai service manager said it is not covered under warranty because the brake pads are a wear item. I asked him to show me in the warranty where a defective caliper is a wear problem with no response. They would not fix the vechicle under warranty. Upon searching the internet, I learned that this same thing happened to many people and is apparently a very common problem. The posts also reflect the exact same experience with the Hyundai dealership in their refusal to admit that a mechanical defect exists. I took the vehicle to my own personal mechanic for the repair and plan on saving the bill and parts for a recall that should occur in the future. Thank you.

Rear disc brake calipers remain closed due to corrosion on slide??? resulting in need of repair worn pads and rotors.

Left rear brake locked up on 2007 Hyundai Sonata. Dealer looked at it and determined the brake caliper was stuck due to corrosion and brake dust buildup, causing the brake to be applied 100% of the time, thus wearing away the pad and causing the backing plate to contact the rotor. Dealer said this was a common failure on Sonata in areas where road salt is used. Pads replaced and rotors resurfaced. Not covered under warranty. Car has 20,000 miles on it.

The contact owns a 2007 Hyundai Sonata. During a routine inspection, a technician concluded that the brakes were wearing prematurely due to the calipers not releasing the brake pedal. There were no warnings indicative of the failure. The vehicle identification number was unavailable. The failure mileage was 55,000. The current was 57,000.

Premature wear of rear brake caliper pads due to corrosion on caliper guides.

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.

22,000 miles on my Hyundai Sonata and the left rear wheel brake caliper stuck. The stuck caliper left the pad against the rotor. Both the left rear wheel rotor and both rear brake pads had to be replaced. The Hyundai dealership would not cover the repair under warranty and I had to pay almost $400 dollars to get it fixed. I have never had a car with only 22,000 miles have a brake problem like this.

Rear brake calipers failed/locked with 20,000 miles on the car.

The car now has 75k. I have needed to replace the rear pads three times and rear rotors twice. In addition, rear brakes have required "friction religning" at least annually, often twice per year. No matter how often these maintenance procedures are needed the emergency or parking brake, which I use each time I park the car, often does not release easily or fully. If I reverse up to about 8-10 mph and slam the brakes, when the dragging sound and sensation do not quickly abate, this seemed to seat the pads and or calipers. In the past week, in fact, the rear driver's brake assembly, aluminum wheel and components become very, very hot. . . Have not needed to drive more than a mile or two at any time, but the dealer can not get me in until next week. . . I am unable to get around at all if need leave the car for extended time. . . It was when online seeking a temporary means by which I might try to adjust the caliper for the time being, that I found many, many forums and discussions of the deficiencies of the rear brakes in Sonatas. . . I did call Hyundai, they issued a case number and they would look at whatever. . .
