What is the reason for the starter noise when starting the car?

The reasons for the starter noise when starting the car are: 1. Engine belt issue: Check the tightness of the engine belt. If there is a problem, it is recommended to replace it. It could also be that the belt is too dirty, and cleaning it with water or lubricating it with a lubricant can eliminate the noise; 2. Noise in the engine compartment: Open the front cover and carefully check for any foreign objects. Blockage by foreign objects can cause a buzzing noise, so it is important to develop the habit of regularly inspecting the engine compartment; 3. Slow return of the starter motor's flywheel: After the engine starts, the flywheel drives the starter motor's flywheel to operate, causing noise. If the noise is only slight, it can be ignored. If it is severe, the motor may need to be repaired or replaced.
When starting the car, the starter motor makes noise, a problem I've encountered several times in over a decade of driving. The most common issue is insufficient battery power, causing the starter to turn weakly and produce a grinding sound, as if the engine is about to give up. As the battery ages, its voltage becomes unstable, making the starter prone to problems. Another possibility is severe wear of the gears inside the starter motor, leading to poor engagement with the engine's flywheel and causing a clicking sound when slipping. Poor electrical connections, such as loose battery terminals, can also result in abnormal noises when the starter operates due to insufficient current flow. Additionally, if the starter relay is short-circuited or aged, it may produce a buzzing noise. Ignoring these minor issues can lead to the car failing to start or even breaking down midway. That's why I always check the battery voltage as soon as I hear any unusual noise to ensure a safe drive.
