Why Does the Auto Start-Stop Function Fail in a New Car?

[SpencerLynn]

If the auto start-stop function fails, it could be due to issues with the car's battery, a malfunction in the auto start-stop system, wiring problems, or other reasons causing the system to stop working. It is recommended to have it checked at a repair shop. Accidentally Pressing the Auto Start-Stop Button: Vehicles equipped with the auto start-stop function usually have the system enabled by default. If it suddenly stops working, it might be because the auto start-stop button was accidentally pressed, turning the system off. The owner should check whether the system has been deactivated. The function will not activate under the following conditions: when the engine has not reached normal operating temperature, when the automatic air conditioning has not reached the preset temperature, when the battery charge is insufficient, when the steering wheel is turned after stopping, during emergency braking, or when reversing. Engine Auto Start-Stop Function: The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restarts it when it's time to move again. This system helps reduce unnecessary fuel consumption, lower emissions, and improve fuel economy.
