Does a repaired new car have any impact after being hit?

After a car is hit, it will have some impact on the vehicle. However, a new car needs to be properly run-in, and during the break-in period, the following points should be noted: 1. The engine speed should not be too high: it is best not to exceed 3000 rpm, and a speed of 60-90 km/h is ideal. 2. During cold starts: there should be a warm-up process, and you should wait for the water temperature to change before driving, usually about 3-5 minutes. 3. Do not rush to accelerate: avoid sudden braking and try to maintain a steady speed. During the break-in period, the maximum speed of the vehicle should not exceed 100 km/h, but long-term low-speed driving should also be avoided. Pay attention to gear changes while driving, and do not stay in one gear for too long.
My new car got hit and was sent for repairs. What are the actual impacts after it's fixed? I've driven several cars that were repaired after accidents, and my practical experience is: it mainly depends on the severity of the accident and the quality of the repairs. If it's just minor scratches that only damaged the paint, a dealership using original factory processes can make it look as good as new, and you won't notice any difference when driving. However, if the frame was damaged or structural components were replaced, even with the best repair work, the body's rigidity and safety performance might be slightly compromised—after all, the original factory uses integrated stamping. Additionally, the used car market is particularly sensitive to this. I deeply felt it when helping my brother sell his car—even just a repainted area could lead to buyers haggling for thousands off, and if major repairs were discovered, the depreciation could easily be 20,000 to 30,000 RMB or more. So, I recommend keeping complete repair records to minimize losses when reselling.
The most annoying thing about repaired cars, in my opinion, is the strange noises! My colleague's new car got rear-ended, and after the 4S store replaced the rear bumper beam, the trunk would creak whenever it went on bumpy roads. It took three inspections to find out that the clips weren't tightened properly. When a new car gets hit, even if the bodywork is perfectly repaired, the metal actually has memory. The areas that suffered impact might develop paint cracks or uneven seams a few years later. Electronic components also require special attention. Last time, after I sent my car for repairs, the reversing camera kept malfunctioning. It turned out to be oxidized wiring connectors—something common in flood-damaged cars but also possible in accident-repaired vehicles. If we're talking about the impact, it's true that it's not as worry-free as when the car was first bought.
