Service Brakes Problems of Hyundai Sonata - part 1

While driving at highway speeds, the emergency brake system will apply and alert me. It’s happened twice now in the last 3 weeks. I’ve experienced a random loss of power while driving on the highway with no check engine light on the dashboard. Lastly, at lower speeds the car will randomly jerk while accelerating with no lights on the dashboard as well. I’ve gone to the dealership but they wanted to charge me a diagnostics fee to first look over the vehicle, which I don’t feel I should be on the hook for since the issue isn’t user caused.

In 2023, my Hyundai sonota 2013 hybrid stopped on the freeway putting myself and others at risk. It told me to stop and pull over to a safe spot but everything locked up and I couldn't move it. I had to get a fuse replaced and it cost over $2k. 3 years later, my cars ebrake light has remained on for a few weeks, it will show a battery discharge warning upon starting up sometimes but now I can't even drive it as it displays "check brake and hybrid warning system" alerts appear on the dash display. I've already been terrified for years that this would happen again. This car is absolutely unsafe. It's still under 100k miles and has given me so many problems even though I have taken great care of it. I am taking it to the Hyundai dealership for another diagnostic. The fact that I see so many others online with similar issues leads me to believe that there should be more recalls on this car; moreover, I believe Hyundai purposely designs this models to break down regularly so we can take it to their dealership to be exonerated by their high prices for parts and labor. Hyundai is a con artist company. They do not design their automobiles with the safety of drivers in mind.

Parking malfunction. Parked, running car moved itself to reverse and backed up a driveway crossing a dirt road and hitting a fence and post. This car could have hit and severely injured anyone who was in the path while it was reversing on its own. Car was in reverse and all parking sensors were blaring when the car was found minutes later.

I was heading to work when suddenly smoke started pouring from the air conditioning vents, and the abs and traction control warning lights came on. I hit the brakes to pull over, only to realize I had lost braking power. I managed to steer to the side of the road as carefully as possible and bring the car to a stop—despite having no brakes and a fire burning under the hood. I tried downshifting to slow the vehicle, but the transmission didn't respond, and the cabin began filling with smoke. Once I stopped, there was nothing I could do to extinguish the fire, as the car was completely consumed within seconds. It was a fire in the engine bay; I lost the brakes, and the abs and traction control lights lit up. I assume it was a critical failure in the braking system, most likely involving the abs module.

My 2013 Hyundai Sonata (VIN [xxx]) suffered a driver's airbag clock spring failure, completely disabling the primary restraint safety system. Abs light was on, the horn and all other electronics on the steering wheel were not functioning. All symptoms indicated in the recall this vehicle is explicitly covered under Hyundai extended warranty campaign txxa/txxj for 15 years/unlimited miles. However, Hyundai's validation systems are actively rejecting my VIN and blocking my federal right to a cost-free safety remedy or repair reimbursement. I replaced clock-spring and mechanic suggested I check into the recall. I attached receipt for repairs information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle brakes sound and feel rough when pressing them. And when backing up the vehicle spotted another car turning in and hit brakes automatically. Car jerked hard as if I hit something. Very rough. Made a scrubbing sound. Does the same when pressing the parking button. It perks and makes the scrubbing sound. Just purchased vehicle 2weeks ago. No inspection on it yet. A warning light about the approaching car but didn't know it was going to hit on brakes by itself so forcefully. Car wasn't near the vehicle just in the scenery of the camera.

We were backing up and leaving a parking space when the emergency braking system overrode our driving and forced a stop. This has happened many times, once while turning at a red light (which we had the right-of-way) and our car stopped on the middle of the intersection. Another time was during a turn in a non-traffic light turn lane where timing is important. Our car was again completely stopped in the middle of the road in oncoming traffic.

I have the 2015 Hyundai Sonata with the 2. 5 gdi engine that eventually will seize due to internal damaged caused by manufacture design flaws. My Hyundai threw a p0010 code which causes my car to idle high and causing low vacuum affecting my brakes. I had a diagnostic test done at a Hyundai dealership that told me it was a cvvt cam sprocket issue and that it was the beginning of the end of the engine, they quoted me 3700. 00 but the engine was to far gone and this repair would only accelerate the engine to seize. They said since the engine isn't seize Hyundai will not cover the cost to repair or exchange the engine, I contacted the Hyundai customer service who stated since the repair that is needed wasn't the root cause of the problems associated with the engine swap warranty they were not going to help me even though I explained to them that the cars high accelerating and the braking system been jeopardized and been told the engine is beyond repairs I feel Hyundai should reconsider their decision and help a loyal customer. I have purchased 12 brand new hyundaj since 2001. The customer representative was extremely un professional even suggesting I scrap my car, also I contacted my Hyundai service technician who said Hyundai customer service never contacted them about my car, when they said they spoke with the technician. Also I received an extended warranty on the 2. 4 gdi engine from Hyundai who many Hyundai customers are or have dealt with. I also purchased an extended warranty which I believe should have been extended as well thank you.

Automatic emergency braking blind spot warning/blind spot detection forward collision warning antilock brake system/abs lane departure warning lane keeping assistance I bought this vehicle last month from a dealer and two days later all the warning lights start popping up on the dashboard so I contacted the dealer and told them what was going on with the car they told me to bring it in so that the technician can check to see what’s wrong with it they told me that there’s nothing wrong with the vehicle so I went back home and the same day all the warning lights came back on so now I’m concerned about my daughter’s safety because she use the vehicle to drive to and from school and you never know when the brakes might fail, again I just bought this vehicle a month ago just one month not even a year and it’s having all this problem even though it’s a pre-owned vehicle I shouldn’t have to take it to the shop after one month please help… thank you.

I was turning into a parking spot and the car accelerated unexpectedly. I slammed into a snow bank and my front bumper was damaged.

I contact the Hyundai dealer about my 2016 Hyundai Sonata. For all I know those vehicles have recalls with engine failure/stalling due to premature rod bearing wear, fire risks from malfunctioning electric oil pumps. My car is having those exact problems with the abs lights being on and is also have problems with the vvt sprocket. And the oil I called Hyundai and they said my vehicle only has a recall with the junction box. But my car is unable to go over 60. And is unsafe to drive and the recalls with that type of model car is the same recalls I am having and soon as I've bought the car and had it for some time I am starting to have those problems so I would like to know what’s going on because it is unsafe and I can’t even drive my vehicle I also have a blinking check engine light. I’ve wanted to report this now incase risk of a fire because I’ve did my research and realize these cars that have these type of problems are known for catching on fire.

I began braking and the brakes locked up. Braking to the floor and the car would not stop resulting in a car crash.

I was driving in the evening on 2/7/26. The red brake light came on in the dash and seconds later the car went into limp mode. An alarm went off indicating that the hybrid system was not functioning. The braking performance decreased significantly. The car slowed down immediately and could not exceed 15 mph. My safety was extremely compromised. Luckily I was not on a high speed road or interstate and was able to pull off onto a side road. If I had been on a busier road, I believe that I would have been in an accident. This could have seriously injured myself or others. The vehicle was towed to a repair shop. The braking pump was replaced and that rectified the problem so far. The old part has been disposed of. The problem was reproduced by the repair facility.

To whom it may concern: I am submitting this complaint to report ongoing safety concerns involving my 2013 Hyundai Sonata. I purchased this vehicle in 2022 through financing and paid it off in 2025. Since acquiring the vehicle, I have experienced persistent mechanical issues that I believe may pose a safety risk to myself, my child, and others on the road. The most concerning issue involves the braking system. I have had the brakes replaced and serviced multiple times, yet the brakes begin grinding again within a very short period, including an instance where the grinding returned approximately one month after replacement. Despite spending money on repairs, the problem continues to reoccur. I am concerned that there may be an underlying defect affecting the braking system that is not being properly identified or corrected through normal maintenance. In addition, the vehicle consumes an excessive amount of oil, requiring frequent monitoring and replacement between oil changes. I am concerned that this issue could potentially lead to engine failure or other dangerous mechanical problems while the vehicle is being operated. As a single mother, I rely on this vehicle daily for transportation to and from work and for caring for my family. I have experienced significant financial hardship attempting to keep the vehicle operational and safe. Despite my efforts to maintain the vehicle, these issues continue to occur. I respectfully request that the national highway traffic safety administration review this complaint and determine whether these issues may be related to known defects, recalls, investigations, or patterns reported by other owners of 2013 Hyundai Sonata vehicles. I am willing to provide maintenance records, repair invoices, mileage information, and any additional documentation that may assist in evaluating this matter. Thank you for your attention to this complaint and for your commitment to vehicle safety.

The contact owned a 2013 Hyundai Sonata. The contact stated that while the contact's son was driving at an undisclosed speed, the brake pedal was depressed, the vehicle failed to stop as intended. The contact's son noticed an unusual sound coming from the hood compartment. The contact stated that the sound was as if something was coming through the hood. The contact's son lost control of the vehicle. The contact's vehicle rolled four times before rolling into a ditch. The contact's vehicle caught on fire. The contact's son was still inside the vehicle. The contact's son exited the vehicle. The fire department arrived and extinguished the fire. The vehicle was towed to a local tow yard. The contact's son was transported by a medical helicopter to a local medical facility. The contact's son sustained a punctured left lung, seven broken ribs, a fractured right hip, and additional bruises, minor burns, and bumps. The contact was advised by the insurance company to report the failure to the NHTSA hotline. In addition, the contact was informed of an unrepaired recall associated with the VIN, NHTSA campaign number: 22v312000 (fuel system, gasoline), which the contact was not aware of the unrepaired recall. The contact was unsure if the vehicle had been inspected by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 170,000.

My engine light come on. Air flow notification come on. I had a brake cleaner notification come on.

The contact owns a 2021 Hyundai Sonata. The contact stated that while driving 10 mph and attempting to make a right turn, the brakes independently activated. Neither the dealer nor an independent mechanic was contacted. The check engine warning light was illuminated. The contact stated that the failure had occurred on several occasions. The vehicle was taken to the dealer and an independent mechanic to be diagnosed. The manufacturer was not notified of the failure. The approximate failure mileage was 42,000.

Experienced sudden unintended acceleration causing my car to speed up, lose control, and crash into the vehicle in front of me.

Hyundai Sonata sel - 2022 both leg break and hand break didnt work while driving. Its a very severe issue in this model.

Vehicle: 2016 Hyundai Sonata VIN: [xxx] while stopped in traffic with my foot firmly on the brake, my vehicle begins to accelerate before I release the brake pedal. This is not normal “creep” — the engine increases rpm and the vehicle moves forward as if the accelerator is being applied, even though it is not. This condition has occurred multiple times and creates a serious safety risk. The vehicle surges forward, sometimes 20 mph, unexpectedly and has almost caused several collisions. This rapid acceleration can easily cause a collision with a pedestrian or the vehicle in front of me. The onboard diagnostic system repeatedly reports a camshaft position sensor fault. The sensor has been replaced, but the problem returned, indicating the issue is not the sensor itself but a deeper engine or electronic control malfunction. Because this vehicle uses electronic throttle control, I am concerned the engine control module is misinterpreting throttle and brake inputs and failing to properly apply brake-throttle override. The vehicle is effectively accelerating against the brake. This is a dangerous and unpredictable condition and represents a potential defect in the throttle/engine control system. This is clearly a safety-related issue that warrants investigation before it results in a serious crash or injury. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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 vehicle's emergency brack system is malfunctioning. There have been several instances where the car's emergency brack went on while no coalition was going to happen. Several instances as well happened while in reverse the emergency bracks went on without there being anything behind the vehicle.

The car has two issues. Brake issue (gas pedal is soft and sinks) and engine power ( gas pedal is soft and not responsive) brakes are soft and spongy some times and sometimes hard. Even you push the brake pedal twice or three time it takes long distance to stop. Some times the brake looks good but for short period of time. The brakes inconsistent. I took to the dealer where I bought it hey refuse to repair it. Then I took it to another dealer. First time they said no issue with car then second time they they replace the vacuum pump and they found out one of the piston is not firing. They replace the ignition coil. The car still has issue and not fixed. I filed case with the manufacturer but the manufacturer closed the case. After that I file lemon law case.

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.

The contact owns a 2013 Hyundai Sonata. The contact stated that while driving 45-50 mph and depressing the accelerator pedal, the vehicle failed to respond and hesitated. The brake and the hybrid system warning lights were illuminated. The contact was able to pull to the right side of the road and waited for her husband to arrive. The contact turned off the vehicle and restarted the vehicle, and the vehicle operated as intended. A dealer was contacted. The vehicle was taken to a dealer, where it was diagnosed, and determined that the hybrid ecu needed to be replaced. The contact stated that the dealer checked the error on the brake failure light that was illuminated, but had not yet gotten a response back from the manufacturer. The vehicle was taken to auto zone where it was diagnosed, and determined that the hybrid ecu needed to be replaced. The contact stated that the failure had occurred on several occasions for the past three years. The engine was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure and informed the contact that they have not heard from the dealer. The approximate failure mileage was 128,000.

We think there’s an issue with the abs module and wheel speed sensor because we started having a problem where the brakes wouldn’t work or would stutter. The car would shake real bad it would make an awful grinding sound but normally only when trying to stop at higher speeds or long braking. The only thing that made it stop was to unplug the abs but then other parts of the car stopped working like the speedometer and the sensors around the car. So we got the abs replaced but the new one started doing the same thing. We did some research and it sounds like the same issue Hyundai is having with the palisade. The incident that made us get it replaced to begin with was were driving down the road and we got to a traffic light but when we tried to brake they just didn’t work so we drove through the red light luckily the one person who was supposed to be going saw us and didn’t pull out in front of us so we didn’t get hit. We haven’t taken it to the dealership yet but my sister who teaches automotive repair at the community college is the one who diagnosed it so she said we should report it here so maybe it won’t happen to anyone else. Before we had the brake issue we were having problems with basically everything on the dash not working randomly. We’d be driving down the road and the speedometer and the outside sensors and the gas gauge and the traction control all would go out at the same time it’s the same stuff that went out when we had the abs unplugged so it seems that might be related.

The vehicle experiences a recurring defect where the brake light turns on suddenly and the engine shuts off while driving. The failure appears related to the braking system (brake switch circuit), electrical system (can-bus/ecu communication), and engine control (shutdown/stall). The system remains installed and is available for inspection upon request. The shutdown poses a serious safety risk, including possible rear-end collision or loss of power in traffic. The problem has occurred multiple times. The dealership inspected the vehicle briefly but failed to diagnose or document the defect and returned the vehicle within hours, stating “it shouldn’t be a problem,” even though the issue continues. Hyundai has refused to provide recall documentation or authorize a re-inspection. The only warnings prior to shutoff are the sudden activation of the brake warning light just before the engine cuts off.

The contact owns a 2017 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the contact engaged the hybrid function on the vehicle and the vehicle unexpectedly stopped. The contact stated that the accelerator pedal was depressed; however, the vehicle took several minutes to respond. There were several unknown warning lights illuminated. The contact stated that when the vehicle accelerated, the vehicle jerked abnormally. The vehicle was taken to the dealer, where it was diagnosed and determined that the brake sensors had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was made aware of the failure. The approximate failure mileage was 130,000.

Good day, please note that most of my communication with Hyundai has been over the phone. I sent one an email shortly after the event, and after following up on the phone, I received this following string separately. I can forward you more along the way, but Hyundai is in possession of the call recordings. I was hoping they would cover my repairs, my engine had a lifetime warranty, but during this process I learned that there was a recall for this car that I was never aware of as the new owner. I needed a software update to get any repairs covered. Please reach out to me for more info!.

The contact owns a 2011 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the brake warning light illuminated, and the vehicle shut off. The vehicle was taken to the dealer, where it was confirmed that the failure was due to an unrepaired recall. The contact received notification of NHTSA campaign number: 23v651000 (service brakes, hydraulic). The repair was performed. The failure reoccurred. The dealer was made aware of the failure; however, the failure was not duplicated. The contact was informed that the recall was closed. The vehicle was taken to an alternate dealer, where it was diagnosed with a failed hydraulic abs booster sensor. The contact was provided dtc: c1237/hpu. The contact was informed that the hydraulic abs booster sensor needed to be replaced. The vehicle was repaired. The vehicle was released to the contact; however, the failure reoccurred. The contact stated that the abs warning light illuminated and then went off. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to take the vehicle for a second inspection. The dealer declined to perform the second inspection. The contact was informed that the repair was not associated with the recall repair. In addition, the contact referenced several unknown recalls; however, the contact was informed that the repair was not related to a recall. The failure mileage was approximately 149,000.

Based on what I experienced, the fire appears to have resulted from an internal mechanical or electrical failure that occurred without warning while the vehicle was in motion. No prior issues or dashboard alerts were present at the time, and there was no external impact or damage that could explain the fire.

Driving came to a stop ,light turned green made a u-turn to go to the gas station heard a pop noise smoke came from inside the car tried stopping it but the brake pedal sunk into the ground pressed my emergency brake it was seized wouldn’t go down (never had that issue my brakes always work ) I smelled brake fluid and seen the abs light on the dash then the power started to go out and my girlfriend almost got trapped in the car.

The rubber stopper for the brake light switch on the brake pedal deteriorated and fell apart. This resulted in the brake lights remaining on constantly, cruise control being disabled, and low battery voltage.
