Is it okay if the car door bounces back when opened to the maximum?

It's fine as long as the door stopper isn't damaged, the door can still open and close normally, and the gap hasn't increased. Here's some related information: 1. Door stopper: A safety device designed to protect both the machine and its users, commonly found in cars and cranes. 2. Car door: Provides access for drivers and passengers while isolating external disturbances, offering some protection against side impacts and safeguarding occupants. The aesthetics of a car are also influenced by the design of its doors. The quality of a car door is primarily reflected in its anti-collision performance, sealing performance, ease of opening and closing, and other functional indicators. Anti-collision performance is particularly important because during a side impact, the buffer distance is very short, making it easy for passengers inside the car to get injured.
I've been driving for almost ten years and often see this situation. When the car door is opened to its maximum, it bounces back mainly because the door limiter is at work. This design is originally intended to prevent the door from opening too far and hitting a wall or another car, so when you push the door hard to its limit, the internal spring mechanism naturally rebounds to cushion the impact. There's no need to panic if it happens occasionally, but if it happens every time with such force, over time it may loosen the hinge screws or deform the limiter spring. My experience is that pushing the door to about 70% of its range is enough for getting in and out, which both protects the door and avoids awkward situations. Developing the habit of using the door gently can make the door operation smoother and more durable.
My child used to love pushing the car door really hard, making it bounce back with a loud bang that startled everyone. The door stopper has a spring latch inside – when pushed too forcefully, the spring compresses to its limit and rebounds, similar to pressing the spring of a ballpoint pen. While this might not cause immediate major issues, I've seen some older cars at repair shops develop problems like doors not closing properly or making strange noises while driving due to long-term rough handling. So, I made a family rule: when opening the door, just push it until it stops at the catch position – no need to force it to the absolute limit. Honestly, even the impact-resistant rubber seals along the door edges can't withstand daily battering. Treating it gently helps the car last longer and saves on repair costs.
The door bouncing back when opened to its maximum is a normal protective mechanism of the door stopper. When you push the door to its limit with force, the internal spring automatically rebounds to prevent overload damage. This situation is like punching a wall—the wall remains unharmed, but your hand hurts. Occasional occurrences are fine, but if you slam it hard every day, it may cause the door hinges to deform or the stopper to fail. It is recommended to slow down the force when pushing the door near its maximum angle. Personally, I make it a habit to hold onto the door frame when getting out of the car, ensuring the door stops at a safe opening angle. The hydraulic struts of the door are also sensitive to violent vibrations, so gentle use can extend the vehicle's lifespan.
