Do new cars still need a break-in period?

[OJoy]

After purchasing a new car, a break-in period is necessary. Before leaving the factory, manufacturers conduct a cold break-in for the engine without any load, but other components are not broken in, so further break-in is required for new cars. Additional information: Below are precautions during the car break-in period: 1. Shift gears promptly: If driving a manual transmission model, ensure timely gear shifting during driving to allow even break-in for each gear. 2. Avoid overloading the new car: Overloading can damage mechanical parts. Therefore, within the first 1000 kilometers, domestic cars should not exceed 75% to 80% of the rated load, while imported cars should not exceed 90% of the rated load.
