What to Do When the Auto Start-Stop System Fails?
2 Answers
Auto start-stop system failure should be diagnosed for the cause and repaired promptly at a 4S shop. Specific details are as follows: 1. Accidentally pressing the auto start-stop button on the car, causing the system to shut down. 2. There may be issues with the car's wiring, or other reasons causing the start-stop system to malfunction. It's best to go to a 4S shop for repair in such cases. 3. Faulty components related to the start-stop function may prevent it from working. It is recommended to check at a regular repair shop whether the battery is functioning properly or if there are issues with related components. 4. The presence of high-power electrical appliances in the car or insufficient battery power may cause the system to detect that the battery does not have enough power to restart the engine, thus automatically shutting down the start-stop function.
I remember my car's start-stop system malfunctioned before, it was winter and the system wouldn't work when it was too cold. First, I checked the battery and tried charging it if the power was insufficient. If the battery was fine, it might be dirty sensors, so I asked the car wash technician to clean them during a wash. Restarting the car sometimes helps—turn off the ignition, wait a few minutes, and start again. If the system keeps failing, pop the hood to check if any fuses are blown and replace them if necessary. Although this issue is annoying, it doesn't affect driving safety. I usually recommend avoiding frequent short trips with start-stop to prevent battery drain. Regular maintenance is key, ensuring the vehicle's systems are updated to the latest version.
