2014 Hyundai Sonata Brakes Problems

My vehicle, a 2014 Hyundai Sonata Turbo, is having brake lock-up issues. It seems to be related to the AVS (Automatic Brake System). This happens mostly when the vehicle is parked on a hill and the brakes lock up when I start moving. This has been happening for several months, but my mechanic hasn't been able to find the problem. I made an appointment with Hyundai to find out what the issue is, but they told me there's no recall related to it.

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the Hybrid braking system warning light illuminated. The vehicle was taken to two separate independent mechanics, where it was diagnosed with ABS module failure. The contact was informed that the ABS module needed to be replaced. The vehicle was not repaired. The vehicle was taken to the dealer, where it was diagnosed with ABS module failure. The contact was informed that the ABS module needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The contact had received an unknown recall notification; however, the dealer and the manufacturer informed the contact that the VIN was not under recall. The failure mileage was approximately 90,000.

ABS control unit/pump is leaking. I was told it's not covered under warranty or recall. Local mechanic states they can't repair it because the part has to be properly programed at the dealership. I've spoken with other Hyundai owners and they have had the same issue.

Lost all braking ability while driving. Had towed to a shop and they were finally able to recreate the issue. There are no error codes indicated when they hook up to a computer. Have bled brakes and still not fixed. They are telling me they've done all they can do.

Received recall notice on 4-16-24 and immediately called for an appt to repair ABS problem. I was told that the part was not available at this time and should call back in a couple of weeks. I called on May 2, 2024 and scheduled an appt. for May 7. After waiting for over an hour, I was told that, yes indeed, my car needed repair but could not be done at that time as this was only an inspection to determine that a repair was needed and someone would call when the part is available but they don't know when. I feel like I was given a run around.

ABS module/brakes system goes into limp mode randomly, which causes brake malfunction, throwing codes c1233, c1234 and c1236. There was a recall repair performed by Hyundai about two years ago, however there was two options on NHTSA recall 23V651000/campaign 251. One was to replace a safety plug fuse issue, TSB 23-01-054H . That is the recall they performed. The other recall repair which they did not perform is to replace the ABS module. The Hyundai dealer says I must pay a $225 diagnostic fee for them established they need to do this recall repair . Does that sound correct to you?

My vehicle stopped on the side of the road in oncoming traffic and caused a back up because of my power brake system failing when it should have still been in good condition because I had just purchased my vehicle 7 months ago. The brake light came on made my car slow all the way down doesn’t go over 15 mph and has a skidding sound when braking and it happened again in the street away from home. And this has been seen in multiple vehicles such as the one I have.

While driving it suddenly showing error as “hybrid system warning, stop and do not drive” and “check brakes” then brakes are not working. I turn off the ignition and start car again, then no error.Went to a local mechanic to check codes he can not find anything. This is a serious issue to taken care off as if brakes fail on highway, we may cause an accident. Then I search in google and lot of discussions going around the same incident

I have a 2014 Hyundai Sonata, when I get in and press the brake pedal it is hard to push in and the car won't start till I try to pump the break pedal hard several times till it gives just a bit, then I can start the car up. I know there was a recall for the 2011 and 2012 cars, this report mimics the issue those cars have had a recall for. Once the car starts the brake pedal does work normally, till it sits and then it gets hard to push in again. I took the car to the dealer to be looked at and they wanted to keep it for a week before anyone would look at it, with $200 to start . I couldn't be without a car for that long so they didn't keep it.There were no warning lights and never have been. My fear is that the brakes will fail while driving..

The first time this happened I had just parked in front of my house and put the car into Park when I heard a chiming sound coming from the car, and the message Check Brake followed by Hybrid System Warning! Safely Stop and Do Not Drive on the dashboard. I did not drive the car for severals after this. After that, I started the car with no issues and was able to drive it with no issues but 4 days later I got the same message while out driving, I stepped on the brake and heard a grinding noise and the brake pedal went all the way to the floor. I pulled over, stop the engine, turned off the ignition, waited a couple of minutes afterwhich the car started with no issue and I was able to drive home. Today I took it to Hyundai garage for the service dept to take a look at it. I am waiting to hear back.

April 2,2022 I took my car in for an oil change. Immediately after leaving the car smoked as if it was on fire. I was pulled over by Walls Mississippi police department because they thought the car was on fire. I contacted Hyundai. They have not done anything to fix this situation. I have not been able to drive the car since then. It needed oil a week after the oil change April 2,2022. It smokes very bad. It has lost power. The engine knocks. I had to get a rental car at the rate of $1000 for a 3 week rental. My car note is $578. The car was repossessed today because Hyundai would not fix the car so I could go to work and pay my car note. I have numerous emails and receipts. No one helped me at Hyundai. They are making us pay our carnotes. Pay rental fees out of pocket. They only reimburse you for your rental once your car goes into the shop. All Hyundai dealerships have a 2 month wait time before they will let you bring the car in,otherwise it will sit on the lot for 2 months. I have tried 5 times since 2021 until now to get the recalls done. Hyundai Mt. Mariah Memphis kept the car a week and asked me to come get it because they did not have all the parts to complete the recalls. Hyundai Olive Branch Mississippi stated they have a 2 to 3 month wait time as well. No one has loaner cars. I explained this to the claim person Julia at Hyundai and no one did anything to fix this.

Brake light illuminated & brake pedal travelled farther down affecting stopping of vehicle. ABS hydraulic control unit is leaking brake fluid. Repair shop confirmed leak.

3 months after purchasing this Vehicle from a notorious car company, I have noticed while driving on the Highway that a hybrid system warning message has popped on my dash board with the check brakes light blinking and beeping. The car then started slowing down with the brakes not functioning anymore. The car is only usable again after you shut it off, wait for few minutes and turn it back on. After several investigations by a Hyundai dealer, it turns out the defective part is a Hybrid Power Unit of HPU.

While driving the Warning in my dash appeared Check Brake Hybrid System Warning safely stop and do not drive. The front brakes sounded like they were rubbing against my tire. I stopped the car. Pushed emergency brake off and on (I’ve never had to use this before) turned car back on and it stopped. I’m worried it will happen again.

I was driving in a school zone going 10 MPH and a warning flashed saying "Check Brake" then "Hybrid System Warning! Safely stop and do not drive" The brakes then locked up and the steering wheel became very stiff. I was able to pull over and turn the car off. I turned it back on and the warning was gone. However, the issue continued a couple weeks later and would not reset to a drivable condition, this prompted my husband to take the vehicle to Sterling Acura of Austin to be maintenance. The Power Brake Booster was replaced but the warning still appears sporadically, just long enough to read and then turns off.

went to start my car-ignition locked,brakes are locked along with steering wheel.having a tow company to get my car to auto mechanic to figure out the problem.Worked fine day before-has been parked in driveway for about 13 hours prior,-no messages appeared -this is the first time ever happened.

From the time of my purchase of the car used in 2016 I noticed the the brake would sometimes make a squeaking sound if the brake pedal was depressed suddenly. In September of 2021 I noticed that a Brake Warning light would come on when starting the car. Sometimes the brake pedal would push to the floor as if there was no brake fluid pressure. I took the car to the Hyundai dealer and asked them to inspect and repair the problem. The problem was determined to be the ABS Pump along with the ABS Assembly. The units were replaced at a cost of $908.91. Later in June of 2022 the noise returned and the brake light again began to light. I didn't lose brakes but the light remained on whenever the vehicle was operating. I returned to the same dealer service shop and they inspected the problem and found DTC C1236. They checked pressure and it had 1054 Bar (needs to be 1000 Bar).The technician replaced the Hydraulic Electronic Control Unit and installed a Hybrid Noise Fix Kit. The cost for these repairs was $3351.15. I am aware of problems with other Hyundai model cars brakes. I hope that our car is safe to operate or park. The dealer confirmed the problems for both repair instances. I do not know if any other authorities have inspected this. I don't have the defective parts. The dealer service center retained them after both repairs.

TL* THE CONTACT OWNS A 2014 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 15 MPH, THE VEHICLE WOULD NOT IMMEDIATELY STOP WHEN PRESSING THE BRAKE PEDAL AND THE ENGINE BEGAN TO LOOSE AUTOMOTIVE POWER. MOMENTS LATER SMOKE AND FLAMES WERE PRESENT COMING FROM UNDER THE HOOD OF THE VEHICLE. WATER WAS USED TO EXTINGUISH THE FLAMES. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE LOCAL DEALER (FIVE STAR HYUNDAI 650 RUSSELL PKWY, WARNER ROBINS, GA 31088) WAS NOTIFIED OF THE FAILURE. THE MANUFACTURER WAS NOT YET CONTACTED. THE FAILURE MILEAGE WAS UNKNOWN. INVALID VIN.

I JUST HAD AN OIL CHANGE NO MORE THAN 1500 MILES AGO AND I HAVE NO OIL IN MY ENGINE. IT JUST DISAPPEARS. AND IT CONSTANTLY MAKES A KNOCKING NOISE THAT HYUNDAI IS UNABLE TO FIX. ALSO I HAD MY BRAKES CHANGED AND WHEN I COME TO A SUDDEN STOP, THE BRAKES LOCK UP AND MAKE A LOUD THUD NOISE.

THE LOW TIRE PRESSURE CAME ON, SO I WENT HOME TOLD MY HUSBAND ABOUT THE TIRE WE WAS ON OUR WAY TO PUTTING AIR IN THE TIRE. I WENT TO PUSH ON THE BRAKE TO START THE CAR AND NOTICED THE BRAKE PEDAL WAS HARD(STIFF), I WENT TO PULL OFF AND REALLY NOTICED THAT I WAS NOT ABLE TO PUSH ON THE BRAKE PEDAL TO STOP THE CAR. I HAVE TAKEN THE CAR TO THE SHOP TO SEE WHAT IS WRONG WITH IT
