Can a Car Be Exposed to Direct Sunlight?

It is not advisable to expose a car to direct sunlight for prolonged periods. While the car itself may not be damaged by the sun, prolonged exposure can lead to numerous adverse effects, including aging of the car's interior, fading and deterioration of the paint, hardening of the rubber seals, and even the risk of tire blowouts. Developing the habit of protecting your car from the sun not only preserves its appearance but also ensures driving safety. Adverse effects of prolonged sun exposure on a car include: Aging of the interior—high temperatures can cause plastic dashboards and leather seats to release harmful gases like formaldehyde, resulting in an unpleasant odor inside the car; fading and deterioration of the paint—although car paint is highly heat-resistant, intense UV radiation can still cause it to age, with white paint often turning yellow over time; hardening of rubber seals—prolonged exposure can cause rubber seals to harden and lose elasticity, potentially leading to cracks and reduced sealing effectiveness, which affects waterproofing and sound insulation; tire blowouts—tires, being made of rubber, are susceptible to damage when exposed to high temperatures for extended periods, as road surfaces can become much hotter than the surrounding air, leading to cracking, bulging, and a significantly shortened lifespan; increased risk—if items like lighters or perfumes are left inside the car, they may explode when exposed to sunlight, posing a threat to personal safety and property.
When using your car daily, try to avoid prolonged exposure to direct sunlight. I’ve experienced it multiple times—after leaving the car under the sun for a day, the interior feels like toasted bread. The leather seats crack, and the dashboard fades and warps. The air conditioning starts buzzing with poor cooling performance. High temperatures also accelerate the aging of plastic components inside the car, and electronic devices like the audio system and navigation may overheat or short-circuit. The battery is another issue—it drains faster under the sun and sometimes won’t even start. Whenever I park, I make it a habit to find a shaded spot under a tree or in a garage corner, or simply use a reflective sunshade—it’s easy and cost-effective. Regularly waxing the car or using a car cover can protect the paint and internal parts, extending its lifespan and avoiding costly repairs.
From experience, prolonged exposure to direct sunlight is indeed harmful to cars. High temperatures can cause the interior to soar to 60-70°C, damaging materials like leather seats and plastic panels which become brittle and prone to cracking. Electronic components such as the onboard computer or sensors see increased failure rates when overheated, while the air conditioning compressor works harder. Tires are also at risk of deformation or even blowouts due to accelerated rubber aging under intense heat. For daily parking, opt for shaded areas or invest in a sunshade with thermal insulation to cool and protect. If outdoor parking is unavoidable, regularly inspect the paint and seals for cracks and maintain them promptly to prevent leaks.
