Hyundai Santa Fe excessive engine revving and clanking sound during acceleration, motor replacement needed on Hyundai Santa Fe

Some Hyundai Santa Fe owners report experiencing excessive engine revving and clanking sounds during acceleration, which may indicate various underlying issues that do not necessarily require a motor replacement. Many owners have noted a loud whining noise during acceleration, particularly over 2,000 RPMs, potentially linked to a failing alternator, worn-out bearings, air leaks in hoses, or power steering pump problems. Additionally, loose motor mounts can cause rattling noises and unusual vibrations that might be misinterpreted as engine issues. A common complaint involves a loose heat shield, which is often noticeable when revving the engine in neutral. Furthermore, some 2017 Hyundai Santa Fe models have reported engine problems such as stalling, knocking, excessive oil consumption, and misfires, frequently attributed to faulty sensors, fuel system failures, or component wear. Owners have also mentioned that a 'rattle' noise during acceleration could stem from mechanical issues within the engine or spark knock due to poor fuel quality. To accurately diagnose the symptoms, it is advised to inspect the engine compartment for loose components and test the vehicle, rather than immediately considering motor replacement.
