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 and I need a solution. Hyundai took back the loaner, I have nothing now and they keep telling me they’re going to follow up, but have not followed up with anything I need help. I don’t want to risk my life, driving the car and being paranoid that it could catch on fire and harm me or other people driving in it please help.

2023 Sonata N-Line, complete loss of power while driving on seven (7) occasions over the past year. In all cases above 60mph creating a dangerous condition to myself and fellow drivers while attempting to pull to the side of the road while rapidly losing speed. In all seven (7) cases, the DTC code is P065312. I have asked the dealership to note the recurring issue in my service records and I have reached out to Hyundai, mostly so that if I am involved in a serious accident because of this issue, there is a paper trail for legal purposes. The dealership folks are nice but basically unless the car rolls into the dealership with smoke pouring out of the engine, they want to charge a diagnostics fee and keep the car for multiple days which isn't helpful because like most, I need the car and the issue is extremely sporadic. It is disappointing and I hope Hyundai takes note and provides remedy for the issue sooner rather than later as this is my sixth (6th) Hyundai vehicle and really do like the car otherwise. All incidents below: 01/23/2025 - 9531 miles 01/20/205 - 9128 miles 12/15/2024 - 5500 miles 12/13/2024 - 5374 miles 11/22/2024 - 2409 miles 01/12/2024 - 568 miles 01/08/2024 - 554 miles

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.
