Problem overview

Some Kia Soul owners report experiencing intermittent engine knocking, which can manifest as varying sounds in intensity and rhythm. This issue may stem from low oil levels or insufficient oil pressure, leading to potential engine damage if not addressed promptly. In contrast, some Cummins diesel engine owners report similar knocking sounds, often linked to factors such as fuel quality or adjustments in engine timing triggered by a knock sensor. While both vehicles may exhibit knocking symptoms, the underlying causes differ, necessitating specific resolutions like addressing oiling issues for the Kia Soul or adjusting fuel quality and timing for Cummins diesel engines. It is crucial for owners to investigate these issues thoroughly to prevent further complications.
