What Causes the Start-Stop Function Failure in Buick Excelle?

[VonJason]

There are many reasons why the auto start-stop function in Buick Excelle may not work. For example, when the vehicle's battery charge is very low, the temperature is too high, the pressure in the brake system drops below a certain point, or the outside temperature is too high or too low, the start-stop system will not activate. In such cases, it is necessary to have the system checked with a computer at a 4S shop. Auto start-stop is a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts the engine automatically when it's time to move forward again. Solutions for start-stop malfunction: Engage the starting gear. If neither the starter nor the engine can turn, inspect the starting system for faults, checking the battery's charge status and terminal connections. If the battery is normal, examine the starting wires, fuses, and ignition switch for damage, replacing them if necessary. Press the accelerator to a medium position; if the engine starts, the issue may lie with the idle control valve, its pipelines, or an intake pipe leak, requiring attention at the nearest 4S shop or repair facility.
