Is It a Problem to Leave a Car in the Sun?

Leaving a car in the sun can easily damage the car's paint. It is recommended to park the car in a shaded area. Below is a detailed introduction about car paint: Overview: The primary function of car paint is to protect the car body from corrosion. Additionally, car paint enhances the vehicle's aesthetic appeal. Car paint is also a type of coating. The purpose of a spray booth is to provide a clean, safe, and well-lit environment for car painting, ensuring that the spraying process is free from dust interference and maintaining the quality of the paint. Composition: Car paint mainly consists of resin, pigment, additives, fillers, curing agents, solvents, etc. Metallic car paint usually includes reflective metal flakes (aluminum powder), while pearl paint typically contains mica particles.
My car often gets exposed to intense sunlight in summer, and over time, I've noticed quite a few issues. The paint becomes noticeably brittle, especially on dark-colored cars, feeling extremely hot to the touch, and the glossiness diminishes. Plastic interior parts warp more obviously—I've seen several cars with dashboard edges curled up from sun exposure. Tire pressure also fluctuates significantly after prolonged exposure, so it's essential to check it frequently in summer. The most annoying part is the cabin turning into a sauna after being baked in the sun, with a wave of heat hitting you when opening the door. It takes forever for the AC to cool it down, wasting fuel and making the ride uncomfortable. I recommend using a windshield sunshade to mitigate some of these effects, and parking in an underground garage is the best solution.
