general problems of the 2013 Hyundai Sonata - part 1

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.

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.

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

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.

Sudden brake failure while driving at speeds around 40 mph, where both the accelerator and brakes became unresponsive, forcing me to coast before regaining limited braking ability after repeated pumping or having to "restart" the car completely. During these events, loud grinding or dragging noises and vibrations were present. Despite adequate brake fluid levels and pad condition, the brake pedal went to the floor. Could be a potential hydraulic or booster failure. It is available for inspection upon request. I was in the car with a significant other at the time of the incident, this happened around 9 times on a very busy highway during a rush. I have been able to reproduce the problem on my own but has now been inspected by a dealer or independent service center. Online resources indicate others with the same symptoms under same conditions have. The component has not been manufacturer, police, insurance representatives or others. But I have very recently (around 4 months ago) passed a vehicle inspection. There were no warnings or other symptoms prior to failure, it's very sudden and having no idea when and where it would happen makes the car inoperable.

Braking system failed on my Hyundai Sonata hybrid 2013. I was driving on the highway and suddenly the vehicle started a constant beeping noise and the dashboard illuminated with a message that read "hybrid system warning! safely stop and do not drive" as I driving 70 mph on the highway, causing me to have to swerve onto the shoulder to avoid being rear-ended by vehicles traveling behind, this is a very dangerous issue, and Hyundai is placing safety of others on the lower rung of their priority list. I had the vehicle taken to the shop where I was initially told that the issue is contaminated braking fluid, the need to replace brakes and the brake master cylinder. Shortly after being notified of the issues that technician diagnosed I agreed to have these items replaced. However, when I went to pickup my car after being notified that services were "completed" the vehicle continued to have the same issues, the vehicle never made it off of the Hyundai car lot. The vehicle has been with Hyundai for over 2 months and suddenly I am being told that there is an abs issue and that it will cost over 5,000 dollars to complete repairs. I scoured the internet and noticed that there are many other complaints similar to mine.

After starting, got a warning stating check hybrid braking, do not drive. When going forward, brake pedal went to floor, heard heavy grinding noise and vehicle stopped accelerating. Had to use the emergency brakes to avoid an accident. Hyundai says they can’t find a problem. Now I can’t even drive it back to the dealer! did an internet search and many other hybrid owners have reported the same issue. I just want to have Hyundai buy the car back at this point. It only has a little over 50,000 miles on it.

There is no lights at all on the brake lights but the brake light in the back window stays on all the time the dim head light only lets one side work.

I was pulled over by law enforcement due to both brake lights being out. Further investigation while changing the bulbs for the 3rd time in 1 year found the housing was deformed and plastic around the bulb housing was melted. The left light bulb was completely black and was difficult to replace the plug back into the plastic housing. The right light bulb metal piece melted into the socket and the glass part of the bulb fell off the metal piece and would not come out of the brake light assembly as if it was now to big to fit throught the hole. This bulb broke off the metal piece and fell into the brake light assembly. After using pliers to remover the broken metal piece from the bulb socket. The new bulb was placed and still could not fit in the hole it is designed to fit. Further inspection reveals the plastic housing the bulb should fit has melted and can no longer accept the new bulb or removal of the previous bulb. This is a safety hazard as the bulb and wiring gets too hot and could heat up the plastic to the point of burning the inside of the trunk. As well as continuing replacement for the bulb of which now cannot be replaced. Potenial safety risk for an accident if the brake lights cannot be replaced due to warping or melted housing. There was no warning or safety notice provided. Until I researched and found the problem has been reported by many owners of this make and model and there is even a recall that went out in January 2024 for the exact issue. I reported this to the dealer who informed me my vehicle is not apart of the recall even though my vehicle meets all requirements of the recall and extended warranty for the recall. Year, make, model, within mileage requirements and the safety issue being present. They want to charge me just to confirm the issue and possible charge for the repair.

Brake lights do not illuminate when parking lights are engaged. We have replaced the socket multiple times. The standard 1157 bulb causes the socket to melt and has deformed the housing for the bulb from extreme heat from the bulb. Replaced the socket 3 times in 3 months this last time it stopped working within 4 days. The obvious safety risk is that cars following the vehicle not being able to determine when the car is braking for a stop at night. The secondary concern is that the lights pose a fire hazard.

The contact owns a 2013 Hyundai Sonata hybrid the contact received notification of NHTSA campaign number: (23v651000 (service brakes, hydraulic) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

After 5 months Hyundai does not have a remedy for NHTSA recall number 23v651000 which is an acknowledged fire hazard. What is NHTSA doing ro encourage Hyundai to move more quickly?.

I see that the recall notice was issued in September of 2023 but I have to say that for no recall remedy to be available yet is disheartening. I drive my car every day and it is the only car I have, because of that I risk my life everyday. My car loses power because of this recall daily and it ranges from 3-6 times a day. I lose power on the highway, the main roads and back roads, it does not matter the speed or time of day. I would like them to push out a fix now. Eventually I will end up in an accident because sadly I cannot afford to get into a new car or a used car.

Submitting a formal complaint to NHTSA regarding unresolved safety defects in my 2013 Hyundai Sonata hybrid. Despite safety recall 251 issued in December 2023 for an abs fire hazard, my vehicle continues to experience sudden loss of acceleration, engine shutdowns, and persistent dashboard warnings. Failed recall repairs & lack of transparency since receiving the recall notice, my vehicle has been serviced multiple times at thompson Hyundai in dundalk, MD, yet the defects persist. When I requested service records to verify recall repairs, I was told that thompson Hyundai’s acquisition by heritage prevents them from providing full documentation—only three edited records missing key details. This raises concerns about: 1. Whether recall repairs are actually resolving safety defects. 2. Hyundai’s failure to maintain proper repair documentation. 3. The risk that other Hyundai vehicles remain unsafe due to incomplete recall fixes. Life-threatening breakdowns & financial hardship since Hyundai’s supposed “fix,” my vehicle has broken down at least eight times, including major highways and intersections. On [xxx], on [xxx], my car suddenly lost power in heavy traffic, nearly causing a multi-vehicle accident. As a result: •I lost my job due to missed work from repeated breakdowns. •I suffered severe emotional distress, including ptsd-like symptoms and asthma attacks requiring medical attention. •I am facing financial instability from lost income and costly rental vehicles. Request for NHTSA investigation given Hyundai’s failure to resolve these defects, I urge NHTSA 1. Investigate whether Hyundai’s recall repairs fully resolve the defect. 2. Review dealerships’ recall documentation practices. 3. Determine if further regulatory action is needed to protect consumers. I am pursuing direct resolution with Hyundai but am bringing this to NHTSA in the interest of public safety. I appreciate your review and look forward to your response.

Hyundai recall 23v651000 has no remedy after 4 months of the start of the recall.

Hyundai is taking too long to fix the campaign 251 recall for the fire hazard associated with the abs system. What can you do to speed up the solution and repairs?.

On 12/12/2023, my brakes failed on my 2013 Hyundai Sonata hybrid on a busy interstate in atlanta, GA. I had it towed to ed voyles Hyundai in smyrna, GA and after "looking at it" they were not able to diagnose the issue. I informed them my brakes went out, they ran a diagnostic test and found where the message came across the dash, but stated it was fine and to bring it back if it happened again. On 1/24/2024, it happened again. My brakes failed and the same alert was sounding off in my vehicle. I took it to ed voyles again and they were finally able to determine it was the abs module on my vehicle. This was due to an electrical short in the brake system. I found out it is the same part as the recall. I emailed the service manager and he agreed. However, Hyundai motor America will not allow them to remedy the issue because they haven't "come up with a remedy". The recall is listed as severe! not only will it catch on fire, but the brakes also fail! there is a burning smell that comes from under my car and I am not sure how there is no remedy for a recall that could cost hma way more than to replace some abs modules. I don't feel safe driving my vehicle and I am not sure how to get more attention to this matter. It is immensely unsafe to allow millions of people to drive in a potential failing brake fire hazard.

The contact owns a 2013 Hyundai Sonata. The contact stated that while driving approximately 35-65 mph, the vehicle decelerated unintendedly. In addition, while turning the steering wheel to the left or the right, there was an abnormal clicking noise coming from the steering column. Most recently, while driving at unknown speeds, the brake pedal required excessive force to bring the vehicle to a stop. The contact stated that it was discovered that an unknown liquid was leaking underneath the front of the vehicle with the check engine warning light illuminated. The vehicle was taken to an independent mechanic who diagnosed that all the drive belts had fractured, and there was a fracture in the oil line and the radiator. The brakes had failed due to the calipers sticking and failed choppers and readers. The mechanic recommended that the radiator, electronic steering bushing, front calipers, pads, and readers be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The contact received notification of NHTSA campaign number: 22v312000 (fuel system, gasoline) however, the part to do the recall repair was unavailable. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The approximate failure mileage was 100,000. Parts distribution disconnect.

The left front brake caliper fell off and rubbed on the wheel’s rim. When I drove in reverse and hit the brakes the wheel would lock up and I couldn’t move. The dealer replaced the caliper. I had the brakes inspected by the local tire and brake specialists, les schwab. They wrote the inspection as the brakes locking bolt(the bolt that holds the caliper in place) was missing and the caliper was rubbing against the wheel. There wasn’t a warning. But, I did hear a loud clunk right before the brakes failed then the brakes made a rumbling sound as if I had a rock stuck in the brake pad. I asked the dealer to save the broken unit so I could document it but the service department manager for korum Hyundai of puyallup tried to pass off a different unit. I took pictures of both my unit (on the car) and the unit the manager was trying to pass off.

See attached document for complaint.

The fix for campaign 251 recall is taking too long.

The active hydraulic booster(ahb) failed while I was driving. While driving 70 mph down the highway the car began to beep and immediately the breaks began to lock up and brake pedal went all the way to the floor. All I could hear was grinding and it was hard to stop. A car came close to hitting me because the deceleration was so abrupt. I towed it to Hyundai dealership and they confirmed the issue is the ahb. After further research, I learn that this happens more often then expect on this vehicle and at first was very hard to diagnose.

Tail light on but brake lights not illuminating due to bulb melting on the bulb socket. Happened to a lot of vehicle owners online and now happening to me. But no recalls are posted. Was pulled over by police. I checked once I got home and saw that socket is burnt and melted.

When driving with foot on gas car starts to decrease in speed and pedal goes to floor but I lift foot off gas then put back on gas speed increases back to normal.

The contact owns a 2013 Hyundai Sonata. The contact became aware that the brake lights were illuminated without the brake pedal being depressed. The contact restarted the vehicle and the failure persisted. The contact stated that due to the brake lights remaining illuminated, the battery terminal had to be disconnected to avoid draining the battery. The contact stated that after one failure, a mechanic pulled over to the side of the roadway and the contact was informed that a sensor related to the brake lights had failed and needed to be replaced. There were no warning lights illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 18,178.

The engine lost power while getting on the highway. I was able to let off the gas and then go again. This happened several times. I took the car to the dealer where I bought it new. I found out that there was a recall on the brake stopper. The dealership never mentioned this. They said the program was over and charged me $231 for a part that was recalled. Are they allowed to not inform us of recalls? please advise. The dealership is keith hawthorne Hyundai in gastonia nc. 704-824-6010.

I was driving and the brake light came on and I lost the brackes.

Around mid-April of 2023, I was driving and I attempted to lightly apply my brakes and an alarm starts going off. Then the brakes violently start grinding. I went from 50mph to an immediate 10mph. The dealership said they replaced the fuse that should solve the problem. It did not. My car has been sitting at the dealership for a whole year now. They have not been able to update me on when it will be fixed. They have made zero attempts to provide me with a reasonable accommodation for my only form of transportation being their lawn ornament for a year. I lost my job. I lost my place to live. And they are doing nothing. Now they say they're going to be replacing fuses to fix the issue but they already tried that and it did nothing. Every time I call to ask about an update, they put me on hold for over 10 minutes and then say there's nothing they can do at this time. The only thing they have tried to do is attempt to get me to buy a whole new car, which is out of the question because mine is completely paid off. This has seriously affected mine and my child's life. I don't even have a vehicle to go grocery shopping or make it to dr appointments or shoot functions because I have no way to get there.

Hi last week I start my hybrid Sonata 2013 when the engine get hot I start running car withing 5 minutes I was driving 35mph and suddenly my break fail and car start flush warning check brake this is the 4time is very unsafe car Sonata hybrid.

While driving the car when slowing for a stop, or just closing down in traffic the car/engine at times will jerk and lurch while braking. If I am not a safe distance from a car in front of me I could cause and accident and hit a car, so I try to keep a good distance when in traffic and refuse to drive the car on long distances on the highway. I can't predict when it will happen and when it does the slippery when wet signal comes on even though it is not wet or slippery condiitons. I don't trust the car while driving, and have no faith in it's safety. I haven't scheduled an appointment for repair because the last time I did they kept the car for over 20 days due to what they said was a system, sensor failure and charges me $3100,when I got the car back I noticed liquid leaking from the car and then the above started happening. The car is available for inspection on request. Car has not been inspected yet, not sure if I can reproduce every time. But it happen almost every day I drive the car to work within 20 miles of my home. The dealership the last time would not give me a loaner car and I need the car to travel back and forth to work since I live in a place without access to public transportation.
