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.
A melted fuel tank can leak, increasing the risk of a fire.
Dealers will inspect and replace the check valve. The fuel tank assembly will be inspected for damage and replaced if necessary. Additionally, dealers will inspect and update the engine control unit software. All repairs will be performed as necessary, free of charge.

Purchased a new Hyundai 2023 Sonata from McGovern Hyundai Rt 2 May 22, 2023. After two weeks of driving the vehicle, I noticed it hesitates when I push down on the gas pedal. I had planned to have the dealership take a look but have a very busy schedule, the issue continued each time I drove the car to the point it was hesitating, basically pausing as I cross intersections. On the 26th of July I was driving on the highway, as I started to experience issues when stepping on the gas. Entering a tunnel in Boston, I pushed down on the gas pedal and noticed the car was decelerating, I was losing speed, in a panic in the center lane of the tunnel, I was able to get the car over to the far right. The car was shaking aggressively then finally just gave out and I called 911. They towed the vehicle to the police headquarters, I called Hyundai for assistance. Had some hiccups but two days later they were able to service the vehicle, supposedly found a faulty fuel injector. They changed out the 1 faulty injector test drive and said the problem was fixed. I picked up my car on July 28th 2023. There is something still wrong with the car, it still has some hesitation and now misfires. Have not heard from Hyundai, I was assigned a case manager and told someone would follow up, no one has reached out. So lucky my children were not in the car and that i'm safe. I could have been killed, others could have been hurt/killed. This should not happen to brand new cars.

When I approach an intersection to stop my car auto shut off engages. When trying to hit the gas to release my car from auto shut off the emergency auto shut off engages and I must put my car in park. Turn the ignition to off and then crank my car back all the way on. Release the park and drive. This happens intermittently for several weeks and I’ve almost been rear ended several times. I have taken the car to a Hyundai dealership for the issue and they tell me nothing is wrong.

The contact owns a 2023 Hyundai Sonata. The contact stated that while her daughter was driving at an undisclosed speed, the vehicle lost motive power. An unknown warning light was illuminated. The vehicle was towed to the dealer; however, no error code was retrieved. The failure recurred while the contact was driving at 60 MPH. The vehicle was then taken to Serra Hyundai (1503 Gadsden Hwy, Trussville, AL 35235); however, no error code was retrieved, and the vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80.

I was driving on the freeway, at the speed limit, cruising along. Then all of a sudden, my vehicle starts to decelerate from 65 MPH and I push the gas, thinking I must have let up too much on the pedal. However, that only causes the RPM to drastically rise with NO change in my speed. I thankfully managed to maneuver from the far left lane to the freeway shoulder on the far right. The whole time, my speed was around 40 MPH and dropping drastically. Trying to safely navigate a slowing vehicle on a 65+ Texas freeway is an adrenaline-rush that I wouldn’t wish on anybody. I was severely panicking. I was almost hit by several vehicles in my maneuvering. I could have died last night. Once on the shoulder, I tried to start my car. I thought it may be a battery issue, but it turned on. It didn't start, though. The lights came on, as did all of the typical system/dash lights that usually indicate when a car’s engine hasn’t “turned over.” I used Bluelink to call for roadside assistance (since I’m only a little over 2 months into ownership) and waited. I was escorted off of the freeway to safety — thanks to a 3-car police escort AND free city tow trucks — and eventually picked up by Hyundai-serviced AAA. The latter then towed my vehicle to the dealership where I bought my Sonata. My car is currently being checked/inspected by my dealer (North Freeway Hyundai) and I only have gotten the following notice from Bluelink: "A possible condition with your Engine Control System has been detected with your 2023 SONATA on 02/22/2023 at 07:23 am CST. A full system check is recommended to be done soon." I checked and there are no open recalls (currently). Even more concerning, my car recently underwent complimentary maintenance, including an oil change, through my dealer (on February 13, 2023 - I have the receipt), was good on gas, and had no warning lights displaying. Until it stopped running — the time I tried to start it on the side of the road, the dash showed an “engine” light.
