I have been having this problem with the car since May 2022. I was driving normally and the car gave the warning: Hybrid System stop and do not drive - check brakes, well I took the car to the mechanic near where I live zip code 90017 (Pep Boys) I have the note of the service that was done the first was on 11 June/22 and the brakes were changed since I thought this would be the problem and more fluid. The problem continued even with new brakes. I went there again and they check the brake system and they said everything looks fine on 20 June/22. So, I decided to scheduled an inspection at Hyundai in Van Nuys zip code 91404 (29 July/22) and I reported my problem that I was having with warnings check brake all the time while I-??m driving every day, but I don't have another car and I need to go to work. Hyundai also couldn't solve the problem of warnings check brakes and I still having this problem, I get the free way every day to go to work and I'm scared because I never know when a warning will appear and the car practically stops in the middle of the free way ( it happened every day) which is making me feel very insecure with this car because it is dangerous but I-??m tired of this car and this problem I can-??t even go to super market without stop the car because of the warning check brakes.. I will include the photos of the recipes of the services that were made. I would really like to be able to solve this problem and feel safe to drive the car. Thank you.

While driving my 2013 Hyundai Sonata, I smelled fuel fumes coming through my a/c vents for several minutes. I shut the a/c off and rolled the windows down. White smoke began billowing out of my exhaust tail pipe then from under the hood. Being in the far left lane of a five lane freeway, other motorists and I were placed in danger as I had to travel across all lanes of traffic as my vehicle billowed thick white smoke into the air limiting the clear view of other motorists and increasing the chance of causing collisions. I pulled over to the shoulder of the freeway and then lost all power steering and brakes on my vehicle. I applied the emergency brake and brought my vehicle to a stop then turned it off. I looked at the temperature gauge and it read normal range but the check engine light came on along with several other dash lights. Once I turned the vehicle off, flames and billowing smoke began coming from under my hood. Four to five minutes later the fire extended to the cabin then the vehicle was fully engulfed. The fire department arrived and extinguished the vehicle fire. Prior to this drive, I have not smelled any fuel leaks or fuel odor inside or outside of the vehicle. It appears a fuel delivery component was the cause of the issue.

The contact owns a 2013 Hyundai Sonata. The contact stated that while operating the vehicle, the braking system malfunctioned and the vehicle would not immediately stop while depressing the brake pedal, causing the braking distance to be extended. Additionally, while operating the vehicle, the front headlights would flicker off and on. The cause of the failure was not yet determined. The vehicle was not repaired. The local dealer was notified of the failure but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 126,000.

While driving car started beeping and making noises - check engine light, brake light, lcd displayed brake warning and flashed "hybrid system warning! safely stop and do not drive". Brake pedal then went to floor, and engine power reduced. Re-starting the car only cleared the problem for a minute before the warning message re-occurs. Others have encountered this issue resulting in crashes. https://also reported here: https://www.carcomplaints.com/Hyundai/Sonata/2013/brakes/service_brakes.shtml

ON AUGUST THE 15TH MY CAR WAS GOING DOWN SHARPE RD IN BURLINGTON NC AT ABOUT 25-30 MPH GOING TOWARDS ROSS ST. I TRIED TO STOP ON MY BRAKES AND MY CAR WOULD NOT STOP.. AS I TRIED STOP IT I FELT MY BRAKE PEDDLE GO ALL THE WAY TO THE FLOOR. I WAS ABLE TO PULL MY CAR OFF THE ROAD AND SIT UNTIL I HAD A TOW TRUCK COME TOW IT HOME. I HAVE MY CAR AT CHRENSHAW HYUNDIA. I HAVE ALSO BEEN TRYING TO GET MY CAR SERVISED THROUGH THEM AND THEY HAVE ALWAYS BEEN BOOKED U. THAT CAUSES A LOT OF CAR issues when you have to wait on an appointment. I really need my car fixed and I do not have the kind if funds that they are asking.

My safety was put at risk and the life of others as a chime sound began to sound and the "check brake/Hybrid System Warning" was displayed on the dashboard. This caused the car to press the emergency breaks on its own slowing the vehicle to a complete halt on freeway. This malfunction could have caused a multi vehicle collision. This was taken for inspection and Scanned with GDS and C1235 Pressure sensor, is internal in HECU and cannot be repaired, HECU must be replaced. The vehicle is unsafe to drive and pedal sinks which feels like car does not stop. The output signal voltage of the pressure sensor is out of the specified range, the monitoring starts 1 sec after power up. The cause of this could be that there is a faulty pressured sensor and/or open or short of pressure sensor circuit. The pressure sensor installed in the HECU, converts the brake pressure to judge the drivers brake intention when the ESC program is operated. When pressure is applied to the sensor, the resistance of the sensor's strain gauge changes. The change in resistance changes the voltage output from the sensor. A fail safe inhibits the ESC/DBC control and allow the ABS/EDB control. The ESC/DBC warning lamp is activated. A safety recall should be established by this establishment as other Hyundai Sonata Hybrids are having the same malfunctions and are having to repair costs out of their own pockets, $4,300 given quote.

*** Normal driving, brakes went out while driving. *** Car was recently repaired by dealer related to hybrid power relay system failure - fuse and precharge relay failed and forced car to pull over while at highway speeds to side of road then left driver stranded on side of road. This was repaired supposedly. Now just a couple weeks later under normal street driving condition brakes totally went out. Stop light then let off brake and car started beeping and making noises - check engine light, brake light, LCD displayed BRAKE warning and flashed "HYBRID SYSTEM WARNING! Safely Stop and Do Not Drive". The car was unresponsive to acceleration pedal and only slowly moved then puttered a little bit but I managed to get it out of the intersection and into a parking lot under its own power. Brake pedal went all the way to the floor. I used Emergency Brake to stop and park then had it towed. Could have been disaster if I was on highway - which I was at stop light to turn onto when the failure occurred. I am scared of this car now. 2 times in a month it has forced driver to pull over and then become unresponsive. No brakes is the last straw. This is a dangerous car now.

my brakes stop working. The dealership advised that the HECU needed to be replaced. There are several incidents showing online with the same dangerous problem. at home going into my apartment garage the car just started rolling back onto on coming traffic. the brakes just stopped working, I swerved to avoid being hit. The car is at the dealership. There was not any working for this ever expensive problem,

The brake pedal bushing has completely deteriorated and caused my car to be able to shift gears without touching the brake. It also caused me to be unable to use cruise control (which I found out driving down the interstate thank god I wasn-??t in an accident) and caused me to be unable to park my car. Caused my battery to die and left me stranded at work. No pieces to remedy to issue are available. And Hyundai has said there was a recall with earlier models (up to year 2011) my car is 2013 and is obviously effected. I have now had a recall on y seat belts, air bags, engine, seat belt anchors, fuel line transmission fluid sensor and now my brakes. I-??m not sure what is actually ok with this model at this point!!!

I do notice sometimes when I press on the gas, the car looses energy, don't accelerate. It's like the car mph goes down to zero while I'm driving the car which is scary. I step on gas, and it don't move, then it picks up and speed off.

Sometimes my brake lights are on when I am not pressing on the brakes. Why is this happening. It seems that something is malfunctioning because it does not happen all the time.

Brake pedal went to the floor. Horrible grinding sound from all the wheels. Chiming. Hybrid system warning. Was driving and had to pull to the side of the street. Found out that the the hydraulic power unit is at fault and had to be replaced. My car is out of warranty and I had to pay over 2000 out of pocket. Complained to Hyundai costumer service and also to the BBB and they all told me to file a report with you. This is an ongoing issue with the Sonata hybrid since 2019. The information is found in Hyundai forum website. Https://www.Hyundai-forums.com/threads/brakes-failure-on-Sonata-hybrid.155580/page-5 this issue should please be investigated for recall purposes.

When turning the steering wheel I hear a clicking noise like something is loose or broken. There regularly is a burning smell like hot plastic is melting and the brake light constantly burns out. When changing the bulb I noticed the casing appears burned and it is difficult to remove the bulb for replacement. I smell the burning scent when I stop and exit the vehicle. The clicking noice is whenever I turn the steering wheel.
