If the start-stop system fails, it is recommended to go to a 4S shop for repair. The following are the specific reasons for the failure of the automatic start-stop system: 1. The system may be turned off due to mistakenly pressing the automatic start-stop button on the car. Check whether the system is turned off. For manual transmission cars, the automatic start-stop system will only start when the system recognizes that the gear is in neutral, the handbrake is pulled, and the clutch is released when parking. 2. The start-stop system may fail to work due to the engine not reaching normal operating temperature, the automatic air conditioner not reaching the preset temperature, insufficient battery storage, turning the steering wheel after parking, emergency braking of the vehicle, or reversing.

I've encountered the start-stop system malfunction a few times, and there's a proper procedure to handle it. Generally, system failures may stem from an aging battery with insufficient charge or dirty sensors causing misjudgment. I usually start by trying to turn off the system button, wait a few seconds, and then turn it back on to see if it returns to normal. If that doesn't work, I check the fuse box, as many cars have a dedicated fuse that's prone to blowing. If the system fails at a traffic light, manually turning off and restarting the engine might be a temporary fix, but a long-term solution requires a visit to the repair shop to identify the root cause. Never ignore it, as a non-functioning system in congested areas can lead to the engine running continuously, wasting fuel and increasing wear. Preventive maintenance is crucial; regularly checking battery health and cleaning sensors can significantly reduce the likelihood of failures. Always pay attention to changes in the system's status while driving, and addressing issues early is the most hassle-free approach.

When the start-stop system acts up, my experience is to check several key points. System failures are often caused by low battery voltage or malfunctioning electronic control units. Priority should be given to using diagnostic tools such as the OBD interface to read fault codes and determine the specific issue. If no tools are available, observe whether the system indicator light is flashing or not lit, as that's a clear signal. I would check the battery status, as an aging battery can easily cause the system to be disabled; try replacing it with a new one or restarting the vehicle after charging. Also, pay attention to sensor contamination or loose wiring, as these minor issues might be resolved by cleaning or tightening. Regarding safety, it's best to temporarily disable the system after a failure to avoid the risk of delayed starts at intersections. Developing a habit of regularly checking system settings can prevent most problems.

Start-stop system failure should not be delayed, the solution needs to be simple and direct. My approach is to first manually turn off the system button and check if it responds. If that doesn't work, restarting the vehicle sometimes helps; if it still doesn't work, immediately check the fuse box and replace any blown fuses. The fault may stem from battery issues or environmental factors like extremely cold weather. System failure will increase fuel consumption and emissions, don't let it worsen. The safest approach is to promptly visit a professional shop for diagnosis to ensure driving safety and reliability.
