Hyundai Santa Fe fuel gauge and sensor malfunction, potential ball joint issue noted on Hyundai Santa Fe

Some Hyundai Santa Fe owners report experiencing fuel gauge issues related to the fuel level sensor inside the fuel tank, which can trigger a check engine light for code P0463 and lead to erratic fuel gauge readings. These problems may stem from debris, build-up, or wear on the sensor, resulting in inaccurate fuel level readings. To resolve this issue, owners typically need to replace the sending unit, which can cost around $440. Additionally, while there is no specific information regarding ball joint problems, owners are advised to have their vehicle inspected by a qualified mechanic if they suspect any ball joint issues.
