Should You Open the Windows When Parking a Car Under the Sun?

Whether to open the sunroof when the vehicle is exposed to intense sunlight doesn't make much difference. If the purpose is to remove odors, prolonged exposure to sunlight should be avoided, and opening the windows can help slightly reduce the temperature. It is advisable to open the windows for ventilation after the car has been exposed to the sun, as the evaporated formaldehyde can be harmful to health. Consequences of prolonged sun exposure on vehicles: 1. Color fading: Extended exposure to sunlight can cause the car's paint color to fade. 2. Component aging: Prolonged sunlight exposure accelerates the aging of plastic components such as tires, windshield wipers, and the dashboard. 3. Heatstroke: Excessive heat inside the car due to sun exposure can lead to heatstroke for anyone inside, posing risks to life and health.

When parking in the sun, I try to leave a small window gap for ventilation. Under direct sunlight, the car interior temperature can soar to 60-70°C, which not only makes it feel like a steamer when entering but also accelerates the aging of dashboard and seat materials. I've seen many cars develop cracks or fading due to prolonged sun exposure. A small gap helps ventilate and reduce heat buildup inside. Of course, don't open it too wide to prevent sudden rain or dust entry - it's best combined with a sunshade on the windshield. Choosing parking spots wisely matters too; prioritize shaded areas under trees if available. Overall, this simple practice protects the car and makes returning to driving more comfortable and safer. I recommend making it a habit to save on future repair costs.

If the car is parked in the sun, I always leave a window slightly open to prevent heat buildup. Experience has taught me that high temperatures cause interior plastic components to release harmful gases, which can lead to dizziness, discomfort, and health risks when entering the car. I often use a reflective car cover over the windows to block most of the heat, while keeping a window cracked to allow air circulation and cooling. This helps protect leather seats from drying and cracking, extending their lifespan. At the same time, I’m careful not to leave the window too wide for security reasons—using window rain guards or ventilators can provide safer ventilation. Parking in the shade is the best option, such as near buildings to avoid direct sunlight. These small measures can prevent bigger problems and even save fuel.

I would choose to open the windows slightly to maintain ventilation because temperatures soar under intense sunlight. Opening the windows promotes air circulation, reducing the impact of high temperatures on in-car electronics, such as overheating and damaging the navigation system. Simply adding a sunshade or window screen on the glass would be even better. Parking in the shade is the priority.
