Chevrolet Sonic odometer reading intermittently fails despite part replacement on Chevrolet Sonic

Some Chevrolet Sonic owners report experiencing intermittent failures of the odometer reading, even after part replacements. This issue can manifest as the odometer displaying three dashes or dots, which may indicate a deeper problem within the instrument cluster that could necessitate a complete cluster replacement. Additionally, a malfunctioning Powertrain Control Module (PCM) has been identified as a potential contributor to these erratic odometer displays, as the PCM manages the instrumentation. Some owners have also linked issues with the odometer to battery replacements, suggesting that if the PCM is affected during this process, it could lead to display failures. Furthermore, reprogramming the cluster or PCM may be required to ensure proper functionality, and problems within the electrical system, such as faulty connections or wiring issues, could also be at fault. It is advisable for affected owners to consult a qualified mechanic or dealership for thorough diagnostics and appropriate solutions.
