The Chevy Cruze may experience a ticking noise, known as "piston slap," caused by the pistons in the lower part of the engine. This is a significant problem that necessitates a complete engine rebuild to fix. The noise is created by the piston skirts hitting the cylinder walls as they move, causing the pistons to rock within the cylinders and leading to premature combustion.
The familiar ticking you hear from piston slap is a noise that comes from the lower area of the engine, where the pistons are moving inside the cylinders. If you're experiencing piston slap, you might have to consider replacing the entire lower section of the engine to eliminate the sound.
