Kona Fuel Level Sensor Fault

I had a similar problem with my Kona. Not sure about the year, but the symptoms sound almost identical. Check engine light, stalling... it was a nightmare. At first, I thought it was bad fuel, but the problem kept happening even after changing gas stations. I ended up replacing the fuel level sensor, but before that, did you check the wiring harness and connections to the sensor? Maybe there is a bad connection or a broken wire.

Thanks. You mentioned checking the wiring harness. Were there any specific wear points or common failure locations you saw when you checked, or anything that helped you find the error?

Honestly, I didn't find anything obvious with the wiring at first, but fiddling with the connector seemed to temporarily fix it, which made me think it was a connection problem. But the problem came back soon after. I just gave up and took it to a workshop. They replaced the sensor, and that fixed it. You might save time and just go straight to a mechanic.

I appreciate the advice. Based on your experience, I had the sensor replaced by a workshop. The repair, including the sensor and labor, cost 52€. The issue is resolved. Thank you for your help!
