Does the Engine Start-Stop Need Repair If It's Broken?
2 Answers
Engine start-stop needs repair if it's broken. It is recommended to have it inspected and confirmed at a professional repair shop or 4S store. Origin of Engine Start-Stop: Engine automatic start-stop technology was developed in response to urban traffic congestion. In city driving, frequent stops and starts are inevitable. When the vehicle idles, the engine runs without load, which not only consumes fuel but also produces exhaust harmful to the urban environment. With engine automatic start-stop technology, when the driver presses the brake pedal to stop the vehicle, the automatic start-stop system controls the engine to shut off automatically. Upon releasing the brake pedal and pressing the accelerator, the engine automatically restarts. Benefits of Engine Start-Stop: The advantage of this function is that, without changing the driver's habits, it saves fuel consumption and reduces vehicle exhaust emissions through engine automatic start-stop.
I've been driving for ten years and recently encountered a problem with the start-stop system. When stopping at a traffic light, the engine wouldn't automatically shut off. At first, I thought it didn't matter since the car could still run. But after a while, fuel consumption noticeably increased, averaging an extra liter per 100 kilometers. After taking it to the repair shop, the mechanic said it might be a sensor malfunction. If left unrepaired, it could lead to excessive battery discharge, increased strain on the starter, and even potentially burn out the control module, resulting in higher repair costs later. I suggest you get it fixed as soon as possible, as the system is designed to save fuel and extend component lifespan. Ignoring small issues can lead to bigger problems. Also, paying attention to battery health during regular maintenance can help prevent similar faults from occurring.
