The abnormal sound of Buick Hideo's driving door may be due to the aging and hardening of the door sealant. Due to long-term use, the sealing strip will harden and lose its soft elasticity, so when the door is opened and closed, it will rub and squeeze each other, resulting in abnormal sound, and the car will make a noise if it shakes slightly. At this point, it may be necessary to replace the sealing strip.
