FUEL SYSTEM, GASOLINE

Hyundai Motor America (Hyundai) is recalling certain 2020-2023 Sonata vehicles. A damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, melting the tank.

Car was parked, full stop, doors shut, seatbelt on. Foot on brake. Car then seemed to lurch forward by itself forward hitting parking cement block.

I'm a person who drives speeed limits, and ulta careful when i drive, and parked at this place/spot for years. This has never happened not sure why it did. No injuries or other people involved thank god, but scared the heck out of me. Wracking my brain, my recalls and software and service appts are up ro date.Nothing out of ordinary that day. I'm confused and shaken, why the first lurch forward and why did going in reverse move it forward? ugh. It drove home fine. Commute to work daily for years, no issues.

My Hyundai Sonata 2023 is experiencing two recall codes. The first one was 9b1 which was resolved, but the other one is indefinite which is 286. I dropped my car off on December 4 of 2025 and a month later Hyundai’s corporate team reached out to discuss the state of my car. They asked me for things such as the payoff balance of what I owe through CarMax who I’m financing the car from, they asked me the mileage on the car, the registration and the lien. They then told me they would provide me with an update by certain dates it’s been over two months and I haven’t received any updates. The car shop called me to come pick up my car because one of the issues was resolved, but after reviewing the recall code 286 and seeing that there is very much so a safety risk when driving the car, I ultimately chose to leave the car with Hyundai. Hyundai has been unsuccessful with providing me with the solution. I’ve waited two months almost 3 months and I believe that this vehicle is a lemon

1. All safety features related to the back up camera, EPS, Traction Control, Lane Assist, Active Cruise Control, Automatic High Beam, Forward Collision Avoidance and more. 2. Loss of all safety features and then sudden restoration of EPS would cause swerve into oncoming lanes or into neighboring lanes and/or ditches. 3. Yes the problem has been reproduced, repeatedly in cold weather and while the dealership has had it in for repairs. 4. No, but the dealership has contacted the manufacturer for repair advice. 5. Yes, every time. I have photos of my dash with the indicating lights on. 10/2/23.

At least 8 times when driving the car the transmission switches from the drive “d” position to the park “p” position and I have to cut off the car and then restart. It is very dangerous as I can be rear ended which can result in personal injury as well as an insurance claim. I’ll put the last date it occurred but started experiencing soon after I bought car.

On January 6, 2026, during my morning commute in heavy traffic, my 2023 Hyundai Sonata engine unexpectedly turned off, causing a sudden loss of power. This created an extremely dangerous situation, and I came very close to being involved in a major collision. While I was fortunate to avoid a crash, the incident posed a direct threat to my safety and life because of the dense surrounding traffic.

Hello Sir/Madam, While driving on Interstate I-75 at approximately 70 mph, the yellow check engine warning light suddenly illuminated. Immediately afterward, the vehicle began to shake violently, lose engine power, and run extremely rough. The vehicle experienced a sudden loss of power, and pressing the accelerator pedal did not result in normal response or acceleration. The throttle input was significantly reduced, making it difficult to maintain speed and safely control the vehicle. At highway speed and in heavy highway traffic, if we had not been able to safely exit the roadway, this loss of control could have put not only the occupants of this vehicle but also other drivers at serious risk. Fortunately, we were already in the exit lane, and a McDonald’s parking lot was located immediately off the exit. This allowed us to leave the highway quickly. Otherwise, this situation could have been extremely dangerous in active, heavy highway traffic. As the vehicle continued to shake

My car was having an issue where it was losing all the coolant, causing my engine to overheat twice while driving down the highway. Unfortunately I couldn't find a leak anywhere and there was no fluid leaking in my garage. I lost an entire reservoir of coolant overnight. After taking my car to the dealership to get repaired, I was told that it was leaking my coolant into the exhaust system and burning it up. I was also told "it was a know issue, they had a bulletin from Hyundai on how to fix the problem, and Hyundai completely redesigned the part to stop the leak and it had to be special ordered." I was without my car for a week and left with a $1300 bill as apparently it was not covered by my warranty. I have no idea how a known issue is happening so frequently that requires a nationwide bulletin and a part redesign, yet somehow is recalled. Especially considering it left me stranded on the side on the side of the highway in Indiana during a snow storm but someone seriously needs to i

I am reporting a serious coolant system defect on my 2023 Hyundai Sonata Hybrid with about 13,500 miles. The vehicle develops an internal coolant leak while driving. Coolant burns off and white steam/smoke comes out of the exhaust, especially during acceleration. When this happens, the coolant level drops quickly, the interior heater stops working, and the car soon displays an engine overheating warning, forcing me to stop driving. This has happened multiple times and makes the vehicle unsafe. When I checked under the hood, coolant was at a low/empty level after overheating events. The car becomes undriveable once the alarm appears. I took the vehicle to a Hyundai dealer, and even though the vehicle is only 2 years old, they told me it was “out of warranty.” I had to pay about $1,500 for repairs, and since the dealer refused a loaner, I paid $250 for a rental car. I called Hyundai USA on 9/13/2025 and opened Case Number XXX. Hyundai acknowledged they are aware of coolant issues o

Fuel injectors cause car to lose power while driving in traffic, on the highway which can cause accidents. This event happened twice one while entering the highway and one while going past a light. Neither caused an accident at the time. The car both times were taken to the dealership and the fuel injectors had to be replaced both times. The first time was in December 2024 at 12k miles

The contact owns a 2023 Hyundai Sonata. The contact stated that while driving at 35 MPH, the fuel mileage abnormally increased from 320 to approximately 431. An unknown message was displayed, and the contact received a notification on the Mobile App about a diagnostic trouble code for the EVAP sensor. The vehicle was taken to the dealer, where it was diagnosed, and determined that the EVAP system valve was stuck open. The dealer replaced the EVAP system, and the dealer then determined that the fuel tank was swollen due to the failure. The contact stated that the rear seat sensor was malfunctioning and was causing a warning light to illuminate erroneously, which the dealer related to the fuel tank swelling and lifting the metal underneath the seat. The dealer also replaced the fuel tank. The vehicle was repaired. The manufacturer was notified of the failure and covered the repairs. The failure mileage was approximately 73,245.

Mileage: 73,245
