It is not good to leave a car exposed to the sun, as it can lead to various problems. Here are the hazards of prolonged sun exposure for cars: Engine prone to overheating: In high-temperature environments, the cooling system of a car's engine has a smaller heat dissipation temperature difference and reduced cooling capacity, making the engine prone to overheating. Battery damage: When the battery temperature is high, the electrodes may oxidize due to insulation layer aging, especially the negative electrode, which can produce white oxide deposits on the terminals, leading to unstable battery voltage. Paint aging: Car paint exposed to intense sunlight is prone to fading or reduced gloss, and may develop cracks. Interior aging: Under high-temperature exposure, the interior temperature becomes extremely high, causing the interior materials to age more quickly.

Leaving a car in the sun for too long doesn't seem good to me. I drive frequently, and in summer, parking under the sun makes the interior as hot as a steamer. Sitting inside feels like burning your buttocks, and the air conditioning takes forever to cool down, wasting fuel and money. The interior materials age easily—plastic parts become brittle, leather seats crack, and the dashboard fades, which is heartbreaking to see. The paint also fades and turns yellow, making a new car look old in just a few years. The battery is prone to losing charge in high temperatures, and if it fails to start, it's a hassle. However, occasional sun exposure has benefits, like killing bacteria inside the car and reducing odors. It's best to park in the shade or use sunshades or car covers for protection, which helps the car last longer.

As a car enthusiast, I've noticed that prolonged exposure to sunlight can cause significant damage to vehicles. The ultraviolet rays in sunlight can oxidize the car's paint, causing it to lose its shine and potentially develop cracks. Interior materials such as seats and dashboards may release harmful gases under high temperatures, affecting health. The soaring temperature inside the car can lead to malfunctions in electronic components like audio systems or navigation. Tire pressure fluctuates greatly, increasing wear and tear. However, some sun exposure can help dry out moisture and prevent mold. I recommend regular waxing to protect the paint, parking in shaded areas or garages, and using sunshades to reduce heat. Regularly check the tires and battery to ensure safety.

From a young person's perspective, I find it inconvenient to leave my car under the sun. The high temperature makes the interior unbearable, and cranking up the AC increases fuel consumption, adding to expenses. The fading exterior looks uncool and affects photos for social media. The interior ages faster, and replacement parts are costly. However, occasional sun exposure can help dehumidify and eliminate odors. I try to park in the shade and use sunshades—they're affordable and effective.

From a health perspective, prolonged exposure of cars to sunlight is not ideal. High temperatures can cause the interior materials to release chemicals, potentially leading to dizziness when entering the vehicle. Poor air quality inside the car can also promote bacterial growth. However, sunlight does have the benefit of killing germs and reducing mold. It's recommended to minimize sun exposure, use sunshades when parked, and maintain proper ventilation.
