What are the effects of slamming car doors?

[KayleeLynn]

Slamming car doors can affect the window regulator, hinges, door stopper, sound insulation layer, door lock, and sensors. Over time, it will reduce the lifespan of the door, damage the window regulator (which may shift or deform), and cause the window to get stuck halfway when rolling up or down, rendering it unusable. The sound insulation layer can also be damaged. More details are as follows: Door damage: While driving, sound insulation effectiveness will decrease, leading to a significant increase in noise; the door may age prematurely, causing hinges and stoppers to loosen, resulting in localized wear, paint peeling, and rust. It can also damage the connections of various plastic components inside the car, causing loose fasteners to rattle. The correct way to close a car door: After exiting the vehicle, push the door to a position 10-15 cm away from the B-pillar, then gently push it closed. This method minimizes noise and reduces wear and tear on the car.
