Chrysler Pacifica 4.0L engine knocking sound with oil light warning on Chrysler Pacifica

Some Chrysler Pacifica owners report experiencing knocking sounds in their 4.0L engine, often accompanied by an oil light warning. These issues may arise from low oil levels, which can starve the engine of oil and lead to harsh knocking. Additionally, the illumination of the oil pressure warning light indicates low engine oil pressure, a serious concern that requires immediate attention to avoid engine damage. Some owners have also noted that the check engine light can signal a range of problems, from minor issues like a loose gas cap to more significant engine or emissions system concerns. The knocking noise may be related to lifter issues, and in some cases, engine cradle rust and corrosion have been reported to cause similar sounds. Furthermore, loud banging noises while decreasing speed could suggest motor mount problems. It is essential for owners to address the low oil pressure warning promptly and seek assistance from a qualified mechanic to diagnose and resolve these issues to prevent further engine damage.
