What Causes Engine Start-Stop Malfunction?
2 Answers
Engine auto start-stop system malfunction may be caused by insufficient battery power. After prolonged use, the battery capacity decreases, which can prevent the vehicle's engine start-stop system from functioning properly. Here is relevant information: 1. Many cars are equipped with an engine auto start-stop system to reduce exhaust emissions and fuel consumption. The engine auto start-stop system can shut off the engine at traffic lights and restart it when the light turns green. 2. If the auto start-stop still doesn't work even after the battery is fully recharged, it indicates that the battery can no longer meet the ultra-high current demand for auto start-stop, and the only solution is to replace it with a new battery. When your car experiences auto start-stop malfunction, it is recommended to seek a mechanic's inspection as soon as possible to identify the cause and avoid other unnecessary losses.
I've been driving a car with auto start-stop function for several years and found that malfunctions often occur. Common reasons include battery depletion or aging, where insufficient power prevents the system from starting; faulty sensors such as temperature or brake sensors, leading to inaccurate detection and system shutdown; extreme weather conditions, especially temperatures above 35 degrees in summer or below zero in winter, which can automatically disable the system; software configuration errors or failed updates, where restarting the key may not resolve the issue; and circuit problems like blown fuses or loose connections, which require thorough inspection. I've noticed that failing to address these issues promptly may cause the car to stall and fail to start on the road, increasing the risk of accidents. It's advisable to regularly check the battery voltage and avoid frequent short trips with the air conditioning on, which can strain the system. I recommend finding a reliable repair shop for a comprehensive inspection.
