ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
Car is still driving good, but after I've had it for a little over a year now the first thing I noticed was my horn went out, then the headlights went out, then my temp gage is flashing and the engine light comes on & off. Certain dash lights come on & off. I just got an oil change. I've been taking my vehicles to Pep Boys for several years now. My last oil change on the Sanoto was the 3rd or 4th oil change . One of the reps told me that my car is now consuming oil. He said it's not leaking on the ground but something is causing the oil to burn. I don't know if you have a warranty on it but he suggested I take it to the dealership. Again I've only had it a little over a year. I'm financing the vehicle and have about 4 more years to go. HELP!

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving as normal and twice about 3 min apart from each other my car went into emergency braking and stopped sudden. No red lights no warnings nothing. Also periodically my car dashboard lights will come on while driving filtering through all the hazard checks. Sometimes it stays on and sometimes it don't. Eventually dash goes back normal. Again all with no warning. Very scary

My cars' dashboard started cracking after about 3 years of ownership (purchased new), which we though was weird. It is almost 10 years old now and the dashboard has cracked all over. I have taken it to the dealership for recalls and repairs and was told that it was a common problem for these cars, which I'm surprised that it has not been recalled. They said that they would report it but I'm not sure. We have owned more than a dozen cars and we have never seen that happen to a car so early on. I'm not sure if it poses any dangers with air bags or other functions, other than visual defect. I'm just trying to get it reported. I also emailed Hyundai.

ELECTRICAL SYSTEM, ENGINE
The electrical and engines in these cars are horrible . The steering wheel keeps locking up while driving cause everything to flick inside the car . This is a major safety issue for me when I am driving and I am unable to control the steering wheel. Dealership claimed they don’t see the issue with the car which I am stating . The vehicle was only inspected by a mechanic and since Hyundai said they couldn’t find anything a 3rd party confirmed that this was a ongoing issue and dealership could’ve caught it but it’s cheaper the sell the car . No everything happens at once especially if I’m turning or driving under 40 mph. First appeared 15 days after I bought the vehicle I alerted the dealership immediately

ENGINE
In April of 2024 initially the car was under warranty. I took my vehicle to the Edmond Hyundai dealership to see why I kept having to put oil in the car in between oil changes. The dealership said iI needed an oil consumption test to determine if the loss of oil amount was excessive. They changed the oil and i drove it 1000 miles and returned it to the dealership. They said it was was around 1 quart low, which is acceptable and "normal". This isn't normal. I tried to get them to check the engine again and do other tests but they wouldn't. It is now October of 24' and I am still putting oil in between oil changes because the light comes on. I took the car back to the dealership on 10/19 and they said the only thing they could do is another consumption test to determine if the oil loss is excessive. I asked them to do a more thorough check of the engine and cited the previous time I brought the car in for the same issue that was not resolved. The mileage is now just over the warranty threshold, but they are still wanting me to pay for whatever service needs to be done to the vehicle, whether it's a combustion cleaning or a new engine. The safety of the car is of concern now and since this car is driven by the three drivers in the family, I do not want them put at a risk on the road if something fails because of oil loss and engine seize. Hyundai needs to be held accountable and honor warranty, safety, and service. The dealers need to help the customer and go above and beyond. The staff at Edmond Hyundai kept going back to the consumption test and all the steps they need to follow before they could send in a submission for doing a combustion cleaning when clearly there was an issue. I am beyond frustrated with the lack of concern for safety and customer satisfaction.

ENGINE, POWER TRAIN
The car is burning through oil at an excecated rate. This is a well-known issue with this make and model. The dealer said they fixed the problem, and they did not. This engine needs to be replaced. It was inspected by a mechanic not affiliated with Hyundai. Hyundai has refused to replace the engine. This should be covered by the 15 year/ 150,00 engine warranty. This engine could seize up at any time. It is a hazard to be driving. The driver is an 80-year woman. She needs help.

STRUCTURE:BODY
The front and rear bumpers of the 2024 Hyundai Sonata have an issue with the bumper brackets. The defective bumper brackets are causing many people's front and rear bumpers to pop out. While these have mostly been 1/8th inch popping off so far, my concern is this may become a bigger hazard as these cars age. Facebook groups with Hyundai Sonata owners have discussed this being a common issue. Those who have had their dealers replace the bumpers/bumper brackets still have recurring issues.

UNKNOWN OR OTHER
The driver’s door and back door stopped opening inside and out. The back door on the driver’s side stopped opening first about 2 years ago, then the driver’s door stopped opening a few days ago. I am fearful of being trapped inside the car in the event of an emergency.

FUEL/PROPULSION SYSTEM
I was driving back from Atlanta, GA to Pensacola, FL when we noticed our fuel level dropping significantly. We stopped in West Point, GA to see what was going on. We turned the car off and back on after 3 minutes and car made a weird vibration. Then the fuel level was rising back to normal but my wife was in the backseat with our [XXX] and she noticed the seat was rising and creating a lot of heat. We pulled over again and noticed it wasn't going down. Luckily there was a mechanic at this gas station and he informed us that the fuel tank expanded and to NOT drive the vehicle. We we're driving alongside my parents so we got in their car and drove back to Pensacola to get a truck and tow attachment cause a tow truck would've costed us $2,500 to tow back to Pensacola.

FUEL/PROPULSION SYSTEM
The component that failed is the fuel tank system. While driving, the fuel tank expanded, causing significant damage to the rear section of the vehicle. This issue resulted in the rear seat rising up, and the bottom rear seat cushion detaching from its securing clamps. The check engine light came on, and gas started leaking from the fuel cap. The fuel tank has moved upward by about 3 to 5 inches, no longer resting on the factory fuel tank straps. The sheet metal underneath the rear seat was crumpled, and the fuel pump access cover bent. The vehicle is currently at College Park Hyundai and is available for inspection upon request. My safety and the safety of my children were significantly compromised. The loud popping noise startled us, and the fact that the rear seat lifted and detached posed a serious risk to the passengers in the back seat. Additionally, the gas leak created a fire and explosion hazard, putting all occupants of the vehicle and other drivers on the road at serious risk. This incident potentially violates the Fuel System Integrity (49 CFR 571.301) regulation, which ensures that a vehicle's fuel system is designed to prevent leaks and fire hazards. Moreover, the unexpected movement and detachment of the rear seat could be a breach of Occupant Protection (49 CFR 571.207 and 571.208), which govern the safety of seating systems and occupant crash protection. The issue has been confirmed by the service center at College Park Hyundai, where the vehicle is currently being inspected and evaluated. The vehicle is being inspected by the manufacturer’s authorized service center at College Park Hyundai. It has not yet been inspected by police or insurance representatives at this time. The check engine light came on immediately after the loud popping noise and the detachment of the rear seat cushion. Additionally, the gas gauge suddenly dropped to empty after the incident, even though the tank was not empty prior to the malfunction.

ELECTRICAL SYSTEM
The BMS module within my cars hybrid system failed causing a parasitic drain on the hybrid battery. The dealership where the work was performed would have to be contacted for pictures. The hybrid battery system swole to a dangerously inflated level and did not produce any codes for an OBD reader to pickup. This has caused the dealership to turn my car away multiple times before finally performing the in depth inspecting required to verify battery swelling. This is a known problem throughout the internet I searched "2021 hyundai sonata hybrid battery dying every day" reddit has plenty of user with the same issues. I am not aware of who has inspected my battery besides the dealership. There was no warnings at all the only reason my battery was finally looked at is because of my persistence.

POWER TRAIN, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On 4 occasions in the last 4 months when I push the gas my cars rpm will go up but the car does not accelerate. This has happened twice on the interstate when trying to merge with trsffic and twice in city traffic, once when making a lefthand turn across oncoming traffic and once just driving down the road. I have taken the car to 2 separate dealerships for a total of 3 times and they drive it a few miles and tell me they can't duplicate the issue. I just picked my car up today after leaving it for 6 days. On my way home the emergency breaking system activated for no reason slowing my car down on the interstate. Both of these issues could get me or someone elas killed. I have not even had this car for 2 years and I am afraid to drive it. Please help. I know I am not the only person with this issue because I can see others on the internet who also have been told that the dealership can't dupe the problem. Even the dealership I just picked it up from said they had another car there with the same problem that they can't duplicate so there is nothing they can do.

ENGINE
My daughter had her car towed to the Hyundai dealership because of engine failure. Upon inspection we learned that there was a recall on the engine. We had to wait a few weeks so that the dealership could get approval and authorization to replace the engine. Finally after 3 or so weeks we got a courtesy car to drive. After about 4 weeks our car was finally ready to pick up so we took the courtesy car back and picked up our car. After about 4 months or so maybe my daughter went to her friends house one afternoon and her and her friend left in the friends car. They had been gone maybe 10 minutes or so and her friends neighbor called her friend and said that her car was on fire and they had already called the fire department but the car was engulfed in flames and before the fire department could get to it the whole car burnt to the ground. Nothing left but the shell of the car. The fire marshal said that the source of the fire was under the hood. Thats where the fire ignited he said. Luckily no one was injured or hurt. But this is after I had the recall motor put in. It was super scary and very upsetting because no one seems like they want to help us either.
