Will a Sedan Spontaneously Combust When Parked Under the Hot Sun?

[Rogers]

A sedan will not spontaneously combust when parked under the hot sun. Below are specific hazards caused by prolonged exposure to sunlight: 1. Tires: High summer temperatures can affect tires under direct sunlight. Due to thermal expansion, tire pressure increases, leading to deformation and accelerated aging, which makes them more prone to blowouts and also increases fuel consumption. 2. Paint: While car paint is quite resistant to heat from the sun, the ultraviolet (UV) rays emitted by the sun can cause damage. UV exposure accelerates the aging of the paint, leading to cracks, water marks, and corrosion marks over time if the car is consistently exposed to sunlight.
