Hyundai Santa Fe knocking noise when accelerating and won't start after dying on Hyundai Santa Fe

Some Hyundai Santa Fe owners report experiencing a knocking noise during acceleration, which may indicate serious engine problems such as ignition or timing issues, or worn lower engine parts. Others describe a rattling sound that could stem from mechanical issues inside the engine or spark knock due to bad fuel or a malfunctioning Knock Sensor. Additionally, some owners find that uneven acceleration might be linked to poor fuel quality, suggesting that trying a different fuel grade could help. Low oil levels or insufficient oil pressure have also been reported as causes of harsh knocking sounds, indicating potential oil starvation. Furthermore, some owners experience difficulties starting the vehicle after it has died, which could point to issues with the fuel system, ignition system, or battery. It is advised that affected owners seek a qualified mechanic to diagnose and resolve these issues promptly to avoid further damage to their Hyundai Santa Fe.
