How to Deal with the Flashing Yellow Start-Stop Light Malfunction?

Excessive carbon deposits in the engine is a major cause, primarily due to the use of inappropriate fuel. As an internal control unit in the vehicle, the oxygen sensor primarily monitors the air-fuel ratio of the engine. During vehicle operation, the oil filter, air filter, and fuel filter must be replaced regularly.

I've also seen many cases where the auto start-stop yellow light flashes, which is mostly due to battery issues, such as aging causing insufficient voltage to support the system's operation. It's recommended to first check if the battery terminals are loose or dirty—clean them and try again. If the light continues to flash, don’t delay—use an OBD scanner to check for trouble codes (some free mobile apps can help) to see if it's a sensor failure or software bug. Regular maintenance is crucial: get a professional battery test at least once a year to avoid worse issues in cold winters. Ignoring it could lead to a complete system shutdown, affecting driving comfort. Remember, early fixes save costly repairs, protect overall performance, and ensure smoother starts.
