Can Cars Be Damaged by Sun Exposure?
2 Answers
Exposing a car to prolonged sunlight will not cause it to be damaged. However, there are several negative effects: 1. Paint: Many car paints are relatively thin, and prolonged exposure to sunlight can accelerate paint aging and fading, causing the car body to lose its luster and affecting its appearance. In severe cases, it may lead to paint cracking, bulging, or peeling, shortening the paint's lifespan. 2. Tires: Tires are made of rubber. Extended exposure to sunlight can cause deformation, cracking, and reduced lifespan. Additionally, tire pressure can fluctuate with temperature changes. During prolonged high-speed driving or sudden braking, localized overheating may lead to tire blowouts.
Parking a car outdoors in summer can indeed be damaging, especially under continuous exposure to the sun. The windshield of my old Accord once developed cracks from sun exposure, and the repair technician explained that high temperatures cause uneven expansion of the glass, making it prone to cracking. Paint fading is even more common, especially with dark-colored cars, which can turn pale within two or three years. The interior also ages quickly—leather seats become stiff and crack after prolonged sun exposure, and plastic dashboard components may warp and creak. The most dangerous risks are items like lighters or perfume left inside the car, as high temperatures can cause them to explode or ignite. I make a habit of parking under shade or using a car cover whenever possible. If neither is an option, I at least install a sunshade to lower the temperature slightly and protect the interior.
