Will the car sunroof break if it is never opened?

[StRonan]

Car sunroof will not break if it is never opened, but it needs proper maintenance to prevent water leakage caused by aging rubber seals. The sunroof's pulleys should be used frequently to maintain their lubrication and flexibility. The sunroof system includes many rubber and plastic parts, which can be corroded by contact with oil or sticky substances. Simply wipe the rubber parts with a regular cloth. The car sunroof changes the traditional ventilation method, allowing wind to create an airflow that draws out the stale air inside the car. When the car is driving at high speed, air flows quickly around the car. When the sunroof is opened, a low-pressure area is formed outside the car. Due to the difference in air pressure inside and outside the car, the stale air inside the car is drawn out, achieving the purpose of ventilation.
