The contact owns a 2010 Hyundai Sonata. While driving 60 mph, the brake pedal was depressed, but failed to respond. The contact placed the vehicle in neutral to slow it down before coming to a complete stop. The vehicle was taken to a dealer, but was not diagnosed nor repaired. The manufacturer was not notified of the failure. The VIN was unknown. The failure mileage was 75,000.

After driving on highway and then slowing for traffic which became stop and go traffic - the brake pedal started slowly fading all the way to the floor. After coming to a stop and pumping the pedal - the brakes seemed to respond but then the same issue repeated - had to have the car towed and discovered that the calipers had frozen on both rear wheels (wheels would not turn freely by hand when car was on lift) and the front right caliper was becoming tight as well. Repair involves new calipers, rotors and pads for all 4 wheels.

Back rear brakes have needed constant replacing since the first replacement in 2013 at 41,658 miles---rear pads and rotars. Eight mos. Later at 48,900, replaced the rear rotars and pads again. Two weeks later at 49,247, replaced rear left flex brake hose and caliper, and deglazed pads and rotars. Six months later at 56,199, the right rear brake was metal to metal and binding--replaced right rear caliper, rotar, and pads. Today, Dec. 29, 2015, with mileage at 67,950, had to fix the back left brakes which emitted a terrible burning smell when used. The mechanic replaced, under warranty, the whole back set of brakes (rotars, calipers, pads). The lug nuts and studs were all seized up from the heat of the left rear brake failure and had to be forcibly removed and replaced by the mechanic. There is something very wrong with the back rear brakes of this car, and these brake failures should not be happening with so little mileage put on the brakes between repairs.

I have had to replace the brake pads three times. Replaced rotors front and rear. Replaced calipers on rear and repaired the fronts. 87000 highway miles. Transmission hard shift from new. Dealer states that they have never heard of any trouble like this.

The electronic stability control (ESC) turns off randomly by its self while the car engine is on. Pressing the ESC button to turn ESC back on does not work. Turning off the engine and then turning it back on sometimes takes care of the problem. When the ESC is off, the breaking system is severely affected where even with a relatively light press on the brakes can result in the locking of the tires.

  • 73,500 miles
Caliper locked up on driver side rear causing rotor and pads to experience severe damage and needed to be replaced. Second time this happened. Previous incident was rear passenger side brakes in March 2013 in which all rear brake pads, rotors and that caliper needed to be replaced. This incident also caused premature wear on front brakes and those needed replacement months later. Dealer would not repair as it was out of warranty mileage.

Sometime w/in the past 2 years, I checked your website for "any" mechanical complaints that had been filed about the 2010 Hyundai Sonata gls. There were 44 (filed nationally) for broken door handles and sticking brake calipers. Well, yesterday (9-6-2014) as I was entering my vehicle in the afternoon, the driver's side door handle "broke completely off." I'm retired, single and very rarely have passengers in my vehicle, thereby little use of the other door handles......just 4 years of using my driver's side door. I'm elderly, not aggressive or rough on equipment, nor in a hurry. It was just a normal pull on my door handle and it snapped completely off. I've even been more cautious about opening my door since I read about prior complaints in the past on your website. Well, I just thought I'd add my "two cents" since doors handles seem to be one of two common problems w/ my model. Overall, when I last checked your website and saw only 44 complaints for the 2010 model, I was impressed......but never expected it to ever happen to me. Bad luck I guess. Hope the dealership honors the warranty when I call them tomorrow. I bought the car new and really like it. It has performed well and I'm very proactive when it comes to maintenance.

Defective rear brakes. One rear brake pad was down to metal. Grinding and smoking. Pads and rotors were replaced by Hyundai dealer. Now at 38,000 miles car is in local shop for same work. One of three pads are down to metal. Diagnosed as defective brake caliper. Claim will be made to Hyundai but many others have been denied per internet and N.Y. class action lawsuit. This is considered to be a possible safety issue.

The rear driver side brake was making a grinding noise. Took to the shop and they say the caliper is working uneven and causing the pad to brake down faster than normal, it was on bare medal. Could this be the crossbar recall causing this to get uneven or an unrelated item? the other side still had 40% pad on it. This seems like a problem to me.

Sonata 4-cyl

  • 64,950 miles
We had to replace the rear brake pads in August 2013 and now in December 2013 having an issue with the rear driver side pad sticking. After hearing the grinding noise again I took it to the repair shop. They are replacing the rotor, pads and calipers for failure to function at a cost of $400. The front pads were still in good condition. These are Hyundai oem brakes. I have been reading numerous complaints about rear brake issues on other 2010 Hyundai vehicles. I have also read that there is a class action law suite in New York over this same issue. I wanted to make a report and possibly find out if there are any plans for an investigation. Hyundai does not seem to have any plans to recall since the issue seems to have existed along time. This is far from normal wear and tear and at the cost of the purposed (by Hyundai service) periodic removal, cleaning, and lubing of the brake pads. This is not normal on any other car and I cannot see this a non issue. That is not to mention the danger of possible brake failure. Is Hyundai waiting for someone to die first?

problem #9

Oct 122013

Sonata 4-cyl

  • 56,660 miles
Vehicle started to make a heavy grinding noise from passenger side rear wheel. Closer inspection revealed a fresh gouge in the rotor. Took the car to the dealer where the vehicle was purchased and was informed that this was a normal wear and tear item, and not covered under warranty (even though a "gold" warranty had been purchased with caliper replacement plainly included). This indianapolis dealership wanted to charge $380 to replace the rear brake pads and rotors. An independent repair shop found that the drivers side of the rear had approximately 40% of the life left on the brake pads and only normal wear to the rotor, while the passenger side was worn down to the metal on the pads and had rendered the rotor unserviceable. It was also noted that the wear indicator on the passenger side was broken, and did not give the normal audio warning of excessive wear. When asked why the rear should wear out faster than the front (which is what all local brake shops told me would happen), the Hyundai service manager did not have any reply. It should be noted that there are several instances of similar failures, and even a class action lawsuit filed in New York state for the exact same issue. A sticking brake caliper is suspected, but could not be confirmed. Rear brake pads, rotors, and hardware were replaced at my expense. The brake caliper was cleaned, lubed, and reinstalled. Dealership would not honor any warranty obligation for this defect. Front brakes also showed at least 40% of their life remaining on the pads.

During an inspection I was informed that the rear brake pads and rotors needed to be replaced. I then took the car for a second opinion which verified that the rear brake pads and rotors needed to be replaced. I was surprised as the car had only about 53K miles and the front brake pads were still good (although I was informed they had about another 60,000 miles). Up to now the car has run well with the exception of the front door latch being replaced which I know is another problem with the Hyundai Sonatas. I did think Hyundai customer service could have been better for both issues.

Sonata 4-cyl

  • 24,206 miles
The vehicle needed rear brake pads and cutting of the rear rotors at 24,000 miles. No matter what your driving habits are or type of driving you do (highway vs. Around town} that is way to early for rear brakes to need replacing. I have checked with various dealers and they all agree that is not normal. Now there is also burning smell that occurs periodically coming from the rear of the car. I brought it to the dealer where I purchased it, hackettstown Hyundai, and they made me wait a week for an appointment and then looked it over quickly and said they smell nothing and see no problem. They were rude and you could tell they wanted nothing to do with the problem. I mentioned there is a class action lawsuit due to premature rear brake wear but they knew nothing and could care less. It seems someone is going to have to be involved in a fatal accident for Hyundai to care. Lets get together and makes them correct the problem before its to late.

Sonata 4-cyl

  • 16,794 miles
I had to replace the rear brake pads on my 2010 Sonata at 16,794 miles on both sides. I had to replace the rear pads and rotors on both sides at 23,156 miles. I had to replace the right rear brake line, pad, rotor and caliper at 25,854 miles. There has been no issues on front brakes, however, I have had to service my rear brakes 3 times. I bought this vehicle brand new from my local Hyundai dealer and it had 4 miles on it. I have spent $768.80 on my rear brakes since I have bought this vehicle in February of 2010. There is clearly a problem with the brake components on this car. The rear brakes should not wear out before the front brakes, and especially a vehicle that has 16,000 miles on it.

Back rear brake sounded like it was grinding and brake pedal very soft. Took for repair while out of state. They replace all 4 break pads and rotors. Next day I went back and complained that I smelled a burning smell and was told that was normal. On July 8 heard grinding sound which was severe on right rear brake. Repair shop owner said the caliper right rear seized and destroyed brakes. All rotors and pads on rear needed to be replaced. The repair shop showed me the pad and rotor from the right rear brake and I saw that there was nothing left of a pad and could plainly see how the meal on both the pad and rotor were ground. I believe that I previously had the brakes repaired but can't remember the specifics.

  • 90,000 miles
The contact owns a 2010 Hyundai Sonata. The contact stated that while driving 25 mph, she applied the brakes but the vehicle did not decelerate. Teh contact applied extreme force to the brakes and the brake pedal traveled to the floorboard before the vehicle began to decelerate. The failure recurred numerous times. The vehicle was taken to a dealer for diagnosis and the contact was informed that the calipers and brakes would need to be replaced. The vehicle was not repaired. The failure and current mileage was 90,000.
