general problems of the 2009 Hyundai Sonata

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. Window electric system won’t let windows go up and down and had to make a latch pull string to open driver door. Passenger door will not open at all and no handle and is a dangerous situation. Break switch not being replaced would have cause an electrical fire and is a complete dangerous vehicle even after being inspected less than a week ago.

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.

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 on 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.

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.

Complete break system as been done as well as tires with rotations, having to replace brakes and rotars often. Continues to pull hard to right while driving and is far from a smooth ride. When breaking the car feels to pull forward. The emergency break does not work at all. This feels like a never ending issue. The car seems to sit low on one side, have to take it to get looked at.

Jerking when brakeing to stop or when slowing to make a turn. Takenseveral times for service but unable to duplicate the problem, no egine ligt has come on therefore they can not repair. Please we need your help.

Stop lamp switch replacement. On 01/14/17 I had an appointment at plaza Hyundai located at 2700 nostrand Ave, brooklyn NY 11210 to replace my stop lamp switch. They did not have the part in stock at that time. The part was ordered on 01/14/2017 and as of this writing (02/17/2017) they have not received the part and have no estimated time or arrival on the part. No one even notified me that the campaign was not completed. I had to come back in the following day 01/15/2017 because my break lights were not turning off. At that time they attempted to charge me for a diagnostic, but I advised the manager that I was there less than 24 hours ago to address the stop lamp switch, which may have been causing the issue. They told me at that time that the part was still on order. They refuse to give me an eta. I called Hyundai's corporate office, and they could not get an answer from plaza auto either. This is a serious recall as it effects my ability to signal that I'm breaking. I will attempt to go to another service department or remedy myself, but I think that this is unacceptable.

Upon accelerating up an entrance ramp to the highway, car accelerated at an unreasonable rate of speed tried using brakes, but they were gone. Car hit speeds of 60/65 mph for more than 3 miles on a turnpike. Parking brake did not work, brake pedal was down to the floor and I could not control the speed of the auto. After traveling more than 3 miles, in the shoulder, I put the gear into neutral and the car began to slow down and finally stop. Towed from turnpike to dealership. Know there have been problems with the 2006 model, but is there anything similar to my experience with the Sonata 2009.

I have a major problem with my brakes. While driving they will suddenly go out. I have to press the pedal almost to the floor to try and stop the car. My car was repaired in September 2015, November 2015, December 2015 and my brakes went out again on yesterday, February 15, 2016 while on the highway. This is a serious problem and could end up being a deadly problem.

Esc light on does not goes when using esc button.

Had to replace brakes twice. After reading 200 complaints online, I have discovered it is an ongoing problem with all Sonatas. The new brakes have to be ground down to fit the Sonata.

Hello, 2009 Sonata: the esc off light comes on. If I shut the car off and re start, the dash light goes out sometimes; may return the next time I start the car. I heard that this is a common manufacture defect. Thank you.

There is a serious problem with the rear brakes on this car and the dealer charged me $550 to fix a problem that should have been covered by a recall as with some of the other Sonata brake problems.

My steering and brakes suddenly locked up. I had my kids in the car and lucky that it happened right by my house. No traffic. Even the suspension was affected. I immediately got kids out of the car and contacted my insurance to tow the car.

When applying brakes, the brakes start sticking, causing the car to jerk. I have taken the car to the dealership for them to tell me they could not see anything that was wrong with the brakes. When I left the dealership, the brakes were doing the same thing.

While driving home, I braked to turn into my neighborhood and was almost rear ended. My friend whom was following me stated that my rear brakes did not come on when I braked. I attempted to park my vehicle and I could not put the car into park but only neutral, nor could I shut off the vehicle. The key would not turn to shut off the vehicle. I had drive the car to a friends garage, place the car into neutral, detach the battery in order to have the vehicle shut off.

I purchased my 2009 Hyundai Sonata in August 2009. In December 2011 I took my car to the dealer for a routine oil change and asked that the brakes be looked at because they were squeaking and the pedal felt soft. I was not sure what the mileage was but I think it was at 34k. I was told that I needed rear and front brakes. I was told my rear brakes were completely gone and my front brakes were at 30 to 40%. Due to financial reasons, I had them fix the rear brakes that day and took the car back to have the front brakes fixed in March 2012. Since that time the pedal is still soft and when I am driving in city traffic the car stops like I need brake, even though I have paid $400 in the last six months for new brakes. I have on more than one occasion had to pull off the road for fear that I would hit the car in front of me. After an exhaustive fight with the dealer I was basically told this was the design of the car. I consider this a huge safety issue and I guess it will be like the Toyota and/or firestone incident. When someone dies because their car will not stop, then someone will take notice.

2009 Hyundai Sonata. Consumer writes in regards to vehicle brakes recall notice. The consumer asked the dealer why had he not been notified of the recall, and the dealer replied, that colorado was not one of the states included. It only covered the east coast, because of the harsh winters and salt used on their highways. The consumer stated on several occasions, he had to take the vehicle to the dealer, to have the brakes replaced.

The contact owns a 2009 Hyundai Sonata. The contact stated that the esc warning light illuminated intermittently. The manufacturer was contacted and informed the contact that the vehicle was not included in NHTSA campaign number 13v113000 (exterior lighting, service brakes, hydraulic). The vehicle was not repaired or diagnosed. The failure mileage was 60,000. The VIN was not available.

The contact owns a 2009 Hyundai Sonata. The contact stated the rear brakes were wearing prematurely. The vehicle was being examined by an independent mechanic during routine maintenance when the failure was diagnosed. The vehicle was taken to an authorized dealer where the brakes were replaced. The dealer did not state why the rear brakes were wearing prematurely. The contact also stated it was unusual for the rear brakes to wear before the front brakes. The failure and current mileage was 11,400. Updated 05/24/lj updated 05/26/11.

I am the owner of a 2009 Hyundai Sonata. The brakes (rear) are supposedly worn out at 16000 miles even though the front brakes are "like new". From reading on line there is a problem with these brakes that Hyundai refuses to ackowledge or repair. I believe that it is time for the nhta to force the issue. How is it that a manufacturer can stonewall everyone when it is obvious that there is a design defect? all any of us get from Hyundai is that htey understand our concern but they will do nothing.

The rear brakes on the Sonata are not releasing fully causing excess wear, brake noise and premature replacement. I bought the car with appx 20k miles on it so I don't know if the rear brakes were replaced before purchase. For me the first replacement came at 31,514 miles, the second about 18,000 miles after that (49,465) and once again about 1500 miles later at 50,973. Hyundai does not recognize this as a problem and refuses to replace them under warranty. Any brake pad/rotor system that fails at an average of 20k needs to be recalled.

The contact owns a 2009 Hyundai Sonata. While the contact was driving approximately 35 mph entering onto a highway into the left lane, unexpectedly the vehicle increased acceleration and the brakes would not function when engaged. The brake pedal was applied repeatedly, followed by no power response. After placing the gear selector into the neutral position the vehicle began to reduce speed. The vehicle was driven into a parking lot and the gear was shifted into the park position and the vehicle came to a stop. The contact was waiting on the roadside assistance for the vehicle to be towed to an authorized dealer at the time of the complaint. The failure mileage was 17,300.

Erratic shifting. Sometimes lurches forward into a higher gear when coming to a stop, nearly causing me to hit car ahead of me. Also front brake rotors are warped causing rumble. I am an exceptionally conservative driver, mildly accelerates and brakes gradually well ahead of stopping. I had the computer upgrade that was supposed to correct the transmission problem shortly after purchasing car at suresky in goshen, NY. This failed to correct problem and I don't have the time nor want to continually spend my saturdays sitting for hours in the service area waiting room. I have read many similar complaints online and it seems that Hyundai chooses not to address this problem. This is my third and will be the last Hyundai purchase.

2008 Hyundai Sonata with under 25,000 miles on it already needs a rear brake job. Was told by our dealer that it is normal because it is a front wheel drive. Was told Hyundai will not stand behind it, however, some dealers will fix it for no charge because it is so ridiculous. The dealer we bought the cars from will not.
