POWER TRAIN
I have been having transmission issues the whole time I've had the car. There is a delay upon take off, and it bogs down instead of downshifting. I was driving my son to school and made a left turn. It started to go but then delayed for 10 seconds before suddenly taking off. If the on coming traffic had been closer, they would've hit us. The dealer has reproduced the problem but can't get enough information for the tech line to approve a new transmission even though the dealership has repeatedly said that is what it needs. I've never had a warning light on it. it's been in the shop for it this time since 7/26/24.

FUEL/PROPULSION SYSTEM
On 3 separate occasions the vehicle decelerated, lights flickered and stated to produce a burning smell through the engine. Each time the car would not allow me to accelerate and eventually stalled out. The car would no immediately start. After a few minutes it would start but not accelerate. After about 30 minutes it would start and would drive about 5-15 mph, enough to get me to my location. On the first occasion I was coming home late in the evening after working a 12 hour shift and had to have a family member get me after being stranded by the side of the road. The second time I was taking my 4 to son to his planned surgery in a bigger city and it broke down on the way. It was not safe driving in the city barely being able to excel but we did it for my son. The third time I was in a larger time in traffic and missed an appointment as I tried to stear my decelerating vehicle out of multiple lanes of traffic to a safe location. I could not use the air conditioner while I attempted to let it rest in 100°+ heat. Each time the lights would flicker and dim. There would be a smoke from the exhaust. After the first 2 occurrences we took it to the dealership but they were not able to replicate the problem or identify a causative code. During the last occurrence we were able to get it to the dealership very slowly and they deemed it to be the fuel injector malfunctioning. This was fixed after about a week or so of being in the shop . About a week or two after the fuel injector was fixed the check engine light came on. We took it back into the service department and they "reset" the system thinking it was an error. The light came back on in less than 24 hours. The vehicle has been running a little harder, not as fast or responsive as normal. A service/evaluation date was scheduled and the code was checked indicating it was likely the catalytic converter. We scheduled another service appointment once the part was in which is 2 weeks from the evaluation appointment.

FUEL/PROPULSION SYSTEM, POWER TRAIN, SEATS
Hello, I have Hyundai Sonata 2023. The fuel tank of this car is expanded on [XXX]. I have never heard about this issue to any cars. I took my car to dealership they said they don’t know why this happened and they said they cannot fix it, my car at the dealership more than a month. I have created a case with Hyundai corporate office in CA, it’s been a month since this case was created and I could reach out to my case manager only twice for this period of time. They are keep saying they are working on it, but no results they don’t even look at my car. Today I barely could reach my case manager and she told me that this is not under warranty and I will need to fix it out of my pocket. When I bring the car to the dealership they told me this not under warranty since warranty was up to 60k miles, I have 90k I asked them to fix it and I will pay but they said they don’t know how to fix it. Today I have researched and found that this issue is really common among Kia K5 and Hyundai Sonata’s 2021 2024, I will provide a link here: [XXX] Please check this link and you can see that most of the cars fuel tanks are expanded and back seats popped up. I have same exact problem. Kia asked drivers to inspect the cars with this issue and they said they will fix it for free since this is fuel tank defect. But what should I do with my Hyundai Sonata. I have same exact issue as you see at the link I have provided. I had powertrain DTC PO451 since march of this year dealership said just check if gas cap is on properly, but this caused this issue I see Hyundai will not help me it will almost 2 month I don’t have my car and I am still paying for it, please let me know what I can do Thank you!

POWER TRAIN, ELECTRICAL SYSTEM, ENGINE
I was driving on the interstate at interstate speeds and the car started to lose power. I was able to steer the car to a safe location and call roadside assistance. It appears that the engine control system had a failure in one of the control modules. The problem was reproduced at the time that I dropped the car off with the service center. The history of the issues for the vehicle are available. My safety was put at risk because the car lost power at high speed and I was only able to limp to a safe location. No warning lights happened until the issue was already taking place. After being notified by my Hyundai app, I was able to discover that the vehicle had a history of having this code (I have only owned the car for 32 days)

ELECTRICAL SYSTEM
2023 Hyundai Sonata Limited, 1.6 T. Battery discharged within 10 days while parked. This problem is well known to dealership. The dealership has to jump start cars and start them frequently on the dealership lot. It is impossible to park this model car at an airport or parking lot for more than a couple of days and maintain a battery charge. No warning or alerts. The problem is that the RESERVE amp hours of the standard stock battery is not adequate to supply the electronic drain of computers while parked.

ENGINE, STEERING, FUEL/PROPULSION SYSTEM
On two separate occasions, one at @9500 miles and the next at @19,000 miles the car engine started shaking and lost all power while driving. Unable to steer car. Both times towed to dealer and they say it needs new spark plugs and need to clean cylinders. They do not know root cause of problem and have not done any testing of the engine, no leak/compression testing. Dealer refuses to cover cost of repairs saying out of warranty but cannot give any assurances this won’t happen again. I’ve requested they contact Hyundai engineers to find out what’s causing this and, to date, they’ve done nothing. Vehicle is unsafe to drive and is still at dealership with no reason to underlying issue.

It almost came to a complete stop but i was able to accelerate again. it was not acting as a safety features because there was not a car close to my front.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
The car would not accelerate, nor switch gear while I'm driving middle of the highway. The car engine started to shake after my car wouldn't switch gear. The car engine would not start after turning the car off and caused a engine misfire. The transmission gear has a hard time switching gear from 0-40mph. This same incident occurred twice since purchasing the car in late November 2022.

ENGINE, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
I have had three occasions where the dashboard lights would flash and the car would lose all power. The first occasion occurred on December 29th at around 12:20 pm at a crowded intersection. The dashboard lights lit up and all of a sudden the car had no power at all. I managed to get it through the intersection and pull it off to the side of the road. To start it up I have to TURN OFF THE CAR by putting it in park and start it up again. This is stressful and terrifying to think about if this had happened on the freeway. Additionally, I took the car to get serviced and was charged a $1,800 bill to fix it in January. This repair took two weeks to complete. The car has since turned off two additional times on February 15th going down a hill at 40 mph and March 26th on a mountain road going 60 mph. I am very concerned this will happen on the highway and I will get into a serious accident or worse. To make matters more difficult, I have taken the car back to the Hyundai dealer again to have it looked at in April and will most likely be without the car for at least another week. I bought the car brand new and the check engine light has gone off four times since then.

SERVICE BRAKES, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The Hyundai Sonata was brought to a stop in a parking lot. When the driver went to put it in park, the vehicle accelerated across the parking lot and smashed into a solid wall. The driver broke her right ankle from standing on the brake pedal. The brakes were ineffective at stopping the vehicle. The collision avoidance system failed to activate or warn of the impending collision. The driver and passenger were severely injured and the car is considered a total loss. There were numerous other injuries sustained. No one outside of the vehicle was injured.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
This is the 3rd time it happened to me. I was driving on the highway at speed 60-70 and a flash came across my dash that said emergency brake warning and my car started slowing down. I panicked and pulled over the road. The warning came on so fast and not even a min it stood on. It went off within 5 seconds. This is a safety hazard and can cause death when this happens. Please issue a recall for this to be fixed because this is dangerous to me and other drivers. I want my money back because this is the manufacturer defect or issue. They need to correct this before fatalities happen.

FUEL/PROPULSION SYSTEM
Had been traveling for approximately 2.5 hours in a winter storm, pushed on brake to slow down and park and the car started to chug. Turned car off and then back on again. Car would not start and had to be towed to nearest Hyundai dealership. There were no warning signs at all, car just suddenly quit. We were later informed that it was the fuel injectors. We were very fortunate that this did not occur in a place with no cell service on a very frigid, stormy night.

EXTERIOR LIGHTING, ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL
Instrument cluster lighting is too bright even on lowest setting. Combined with poor side visibility from headlamps it is easy to hit object or pedestrians when turning on unlit areas. Have run over a curb three times and damaged two wheels because they can't be seen from the overly bright instrument lighting at night.

VISIBILITY/WIPER, VISIBILITY:SUN/MOON ROOF ASSEMBLY
Sunroof burst while driving on freeway at a low speed due to heavy traffic. There were no overpasses or bridges above the vehicle when explosion was heard. No point of impact on sunroof from possible rocks and glass is shattered but in one piece and it appears to have burst outwards as it’s bowing upwards. Sunroof had rarely ever been used prior to this and vehicle is only 1 year old. Only some tiny pieces of glass came off initially, but headliner collected them instead of landing on driver/passenger while driving.

FUEL/PROPULSION SYSTEM
I was traveling on the freeway when I began experiencing erratic acceleration, around which time the check engine light came on. I took the next exit, and continued to experience the same symptoms, as well as rough idling, and a bit of smoke. The car was towed to the nearest Hyundai dealership where the fuel injector was replaced under warranty.
