Will a Car Spontaneously Combust When Exposed to Sunlight in Summer?

[Brady]

No, a car will not spontaneously combust when exposed to sunlight in summer. However, prolonged exposure to sunlight can cause the following damages: 1. Paint: Many car paints are thin, and prolonged exposure to sunlight can accelerate paint aging and fading, causing the car body to lose its luster, affecting its appearance, and even leading to paint cracking, bulging, or peeling, thereby shortening the paint's lifespan. 2. Tires: Tires are made of rubber. Extended exposure to sunlight can cause tires to deform or crack, reducing their service life. Additionally, tire pressure can fluctuate with temperature changes. Prolonged high-speed driving or sudden braking can cause localized overheating, which may lead to tire blowouts. 3. Interior: Many car interiors are made of plastic materials, which can soften and deform under prolonged sunlight exposure. Car seats, usually made of leather, can harden and age under high temperatures, resulting in a poorer tactile feel. 4. Human Health: Since most car interiors are made of plastic materials and components are glued together, prolonged exposure to high temperatures can release harmful gases such as formaldehyde, which can be hazardous to human health.
