Is it a problem for a car to be exposed to sun and rain?

[Mallory]

Exposing a car to sun and rain can cause damage. First Maintenance: Some manufacturers determine the first maintenance based on time or mileage. The exact timing should be referred to the vehicle's user manual or warranty manual. The first maintenance is very important and is usually free, so it's essential to remember to do it to avoid missing it and affecting the car's third maintenance. Maintenance Items: Main car maintenance items include changing engine oil, oil filters, transmission oil, spark plugs, air conditioning filters, air filters, brake fluid, etc. However, not all items need to be replaced in every maintenance session; it depends on their service life. Additionally, maintenance involves inspecting and servicing dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.
