NHTSA Complaint #11695686 — 2023 HYUNDAI SONATA

The fuel injectors failed on my Hyundai Sonata in two instances. Once on 5/23/24 and once on 9/7/25. During the first instance, I was driving on a local road when the accelerator stopped working and the engine started sputtering. We were fortunately able to stop at a nearby parking lot before the engine completely stopped working. During the second instance, I was also driving through a local road when the accelerator stopped and the engine started sputtering again. This time, we weren't able to reach a safe stopping point and the engine died on the road. My family was with me at the time, so we had to push the car in neutral to the closest safe space. In both cases, our safety and the safety was others was put at risk as the car become unable to accelerate, and the car stops moving. We had to get out on the road and push the car with oncoming traffic. The problem was confirmed by the dealer in both cases, and they replaced the fuel injectors in both cases. So far, they've replaced 3 out of the 4 fuel injectors so I still drive in fear of another fuel injector causing a breakdown while I'm driving. There were no warnings or symptoms prior to the failure so there was no way to know to stop driving and to stop in a safe spot. We were fortunate to be able to move the car to a safe place for both instances, but if this had happened on the highway or secluded location, our lives could've been at risk. I've requested Hyundai to replace the last fuel injector but they're refusing to do so. I only feel safe driving in local roads or short highway trips as I fear for the reliability of my car, my safety, and the safety of others.
