Owner reports
Selected complaints filed with NHTSA by 2009 Hyundai Sonata owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2009 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the contact heard a loud grinding noise coming from the rear of the vehicle. The contact took the vehicle to a local dealer to be inspected. The contact later discovered that the dealer only did a visual inspection of the brake pads and rotors. The mechanic stated that there were metal shavings from the brake pads and that the contact should wash the wheels to clear the metal shavings. The wheels were washed as instructed; however, the failure persisted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 181,000.
Brakes seize up while driving and then cannot move the vehicle. This causes a dangerous situation while driving and then breaks lock up and cannot move car even though vehicle is on and then stopped for a stop light. Car must then be turned off and sit for about 30 minutes so it can unseize and when that happens, you can then resume driving and then check engine light comes on. Brake lights were staying on even when vehicle is shut completely off. ABS and ESC lights stay on consistently and never turn off. Vehicle brake switch was replaced at Carolina Hyundai of high point, NC. So break lights have been repaired. They had to order the stop switch lamp replacement for recall as it was never done and will be fixed in next week. 3 door handles fell off and cannot open the rear driver side door at all. …
The problem as reported by so many others that the rear brake system has an inherent failure in the caliper/rotor/brake pads. I have vested nearly $2500.00 on the three for mentioned parts and labor over last 4 years. Between Midas and now a private mechanic have tried better lube on slide pins but the problem still persists. A little research states that the caliper piston doesn't retract from the rotors and in turn heating up the brake components to the point of failure. Some Law firms have stated the problem is a production flaw my problem with a system with this failure rate isn't recognized by the Hyundia. Calipers should simply last 80 to a 100 thousand miles under most driving conditions. Looking forward to your response. Kerry yakel
Brake Calipers are getting stuck often damaging the rotors and pads. This happens even for new calipers and rotors that won't last more than one year after replacement. The parts were original from manufacturer. The rear and front brakes were randomly getting stuck on one wheel after a period of using brakes. This put the vehicle in danger of getting fire from overheating rotors or increasing the risk of a crash because of an unusable brake system. This incident has repeated over time from 2017 till 2025 inducing big spendings for fixing brakes
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. …
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. …

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.
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.
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.
