Can a Car Be Exposed to the Sun for a Long Time?

Cars should not be exposed to the sun for extended periods. Here are some key points about prolonged sun exposure for vehicles: Hazards: The most common hazard is accelerated aging of the vehicle. While the visible effects appear on the surface, smaller plastic components and wiring inside the vehicle also experience faster deterioration under continuous high temperatures. Some might think "a car isn't that fragile - it has a metal body that protects its components," but prolonged exposure still takes its toll. Lifespan: When purchasing a vehicle, sales personnel typically inform consumers about the vehicle's expected lifespan and product warranty information. These estimates assume the vehicle won't be constantly exposed to harsh sunlight. That's why many car owners who value their vehicles regularly take them to auto detailing shops for paint maintenance and protection.
Leaving your car parked under the scorching sun for extended periods is not advisable. From my experience in auto repair, I've seen numerous cases where the interior suffers severe damage, especially the seats and dashboard, which tend to harden and crack under high temperatures. Leather materials fade and age particularly quickly. The paint is also an issue, as UV rays can cause it to lose its shine, bubble, or peel, affecting the car's appearance. And let's not forget the tires—exposure to intense heat can harden and deform the rubber, increasing the risk of a blowout. The car's electronic components are another concern; overheating of the central control screen or wiring can lead to short circuits and costly repairs. The most alarming issue is the summer heat, which can raise the interior temperature above 60 degrees Celsius, causing plastic parts to release harmful gases that are bad for your health if inhaled over time. So, I strongly recommend avoiding open-air parking whenever possible. Using a sunshade or car cover can effectively protect your vehicle and extend its lifespan.
Let me tell you, once I left my car parked in the sun for two weeks during a business trip. When I returned, the seats had cracked with a big gap, the dashboard became as brittle as a biscuit, and the paint turned dull and deformed. The repairs cost me thousands, which was heartbreaking. Since then, I've been extra careful, always trying to park in shaded areas or underground garages. Prolonged exposure to sunlight doesn't just damage the exterior—it also increases the burden on the air conditioning, slows down cooling at startup, and puts extra strain on the engine, leading to higher fuel consumption. Regular protective measures like applying heat-insulating film or using sunshades work well and can save a lot of trouble and expenses. In short, this is a lesson learned from personal experience—never underestimate the destructive power of sunlight.
