2016 Chevy Cruze owners have reported a ticking noise coming from the engine, potentially due to issues like loose spark plugs, a stretched timing chain tensioner, or valvetrain problems. Valvetrain malfunction tends to be a common culprit in most vehicles, causing a ticking sound as the valves move in relation to other engine parts. Maintaining proper oil levels is essential to prevent valvetrain noise and avoid engine damage. Additionally, a faulty purge valve solenoid in the Cruze can specifically lead to a consistent ticking noise that requires replacement.
The primary reason for a ticking or knocking sound in the 2016 Chevy Cruze is often a problem with the fuel injectors.
