Ford Edge engine knocking issue causing performance problems on Ford Edge

Problem overview

Some Ford Edge owners report experiencing engine knocking issues that lead to performance problems. These issues can stem from various factors, including the use of low octane fuel, which may result in suboptimal performance. Additionally, oiling problems such as low oil levels, low oil pressure, or contamination of oil with water or coolant can contribute to engine knocking. A faulty knock sensor is also commonly associated with the P0325 code, which can exacerbate knocking and performance issues. Many owners find that bad spark plugs, essential for proper combustion, are a frequent cause of engine knocking. Symptoms reported include loss of power, engine misfiring, and a noticeable knocking noise, all of which can significantly impact overall vehicle performance. Prompt diagnosis and maintenance are recommended to resolve these concerns and enhance the Ford Edge's reliability.
