It is not normal for the screws on a new car's bumper to have been tightened. Generally, the body parts of a vehicle are adjusted and installed at the factory and do not require later adjustments. Composition of the bumper: The front and rear bumpers of a car are made of plastic. Typically, a car's plastic bumper consists of three parts: the outer panel, the cushioning material, and the crossbeam. The outer panel and cushioning material are made of plastic, while the crossbeam is formed by stamping cold-rolled thin sheets into U-shaped channels. The outer panel and cushioning material are attached to the crossbeam. Function of the bumper: The car bumper is a safety device designed to absorb and mitigate external impacts, protecting the front and rear parts of the vehicle. In addition to maintaining its original protective function, it also aims for harmony and unity with the car's body design and pursues lightweight construction.
It's actually quite common for the screws on a new car's bumper to show signs of being tightened. When I first bought my new car, I also noticed slight tool marks on the front bumper screws and felt a bit uneasy. I asked the technicians at the 4S dealership, and they explained that it's a normal part of the assembly process—workers might leave marks when securing the screws with tools, or adjustments might have been made during pre-delivery inspections. However, they also warned me to be cautious if the screws are loose or the bumper isn't aligned properly, as it could indicate damage during transport or even signs of accident repairs. They advised owners to inspect the paint for uniformity and scratches; if everything looks normal, there’s no need to worry. But if issues arise, like unusual noises at high speeds, it’s crucial to get it checked by professionals immediately—don’t delay. Bumpers are safety-critical, so negligence isn’t an option. During routine maintenance, it’s also a good idea to have mechanics check the screws to ensure they’re properly tightened.
