What could be the reason for the malfunctioning fuel gauge on my 2015 Chevrolet Cruze?

There are a few reasons why the gas gauge might stop working in a 2015 Chevy Cruze. The primary cause is often due to the sending unit failing. This component is constantly moving while the car is in motion, and over time, wear on the contacts can lead to an open circuit. This can result in the gas gauge misinterpreting feedback and display inaccurate tank levels, showing it as always full or empty. Another frequent culprit is circuit issues, usually due to loose connections or corrosion. In most instances, the fuel pump module will need to be replaced. Sometimes, the gas gauge may have failed on its own, possibly due to internal circuit shorts causing it to remain stuck at empty. The least common reason for the malfunction could be a failure in the instrument cluster. If the entire cluster is at fault, it will require replacement.
