Buick Verano knocking sound with engine light on and unusual pulling behavior on Buick Verano

Some Buick Verano owners report experiencing a knocking sound in the engine, which may be caused by factors such as low-quality fuel, incorrect air-fuel mixture ratios, faulty spark plugs, or worn engine components. This knocking sound is often noticeable during idling, high speeds, or under load conditions. Additionally, some owners have reported that the engine light turning on can indicate various issues, including low oil levels, ignition system problems, or a faulty knock sensor that fails to detect engine knocking. Furthermore, unusual pulling behavior has been linked to potential problems with the engine or drivetrain components, such as worn ball joints or issues with the crankshaft.

Prompt attention to these symptoms is crucial to avoid further damage and ensure the safety and performance of the Buick Verano.
