Yes, exactly! It's hesitating, and the fuel consumption seems a bit worse than usual. What was the issue with your Sonata? Was it the torque converter itself?

Yes, it turned out to be the torque converter. Given your symptoms and the error code, it does sound like you're facing the same issue. I advise you to take it to a workshop as soon as possible for a professional check.

Thanks for the info. My local mechanic confirmed it's a defective torque converter lock-up clutch. The repair is going to cost around 2120€. Not ideal, but at least I know what it is now.

Sounds familiar. Is it struggling to shift smoothly, almost like it's hesitating? Any difference in fuel consumption? It could be a converter fault.
