As of late, the fuel gauge has been acting very erratically. The low fuel light is lit even when the fuel tank is full. As I'm driving, the amount of fuel on the fuel gauge fluctuates from empty to 3/4 or from full down to empty. Seeing that there are several complaints about the same thing, Hyundai should issue a recall - obviously this is a defect with the fuel sensor. Overall, this vehicle has been a really good vehicle, but this fuel gauge thing is starting to drive my crazy. I'm afraid one day I'll run out of gas in the middle of nowhere because the fuel gauge is giving me a false reading!.
Fuel sensor is bad and causing the fuel needle to fluctuate and give incorrect warnings about low fuel and amount of fuel left in the fuel tank.
