Should New Cars Be Exposed to Sunlight?

Generally speaking, there's no real need to expose a new car to intense sunlight. Simply ventilating it by opening the windows while parked in the sun is sufficient. Below are the hazards of sun exposure and maintenance tips for new cars:

Hazards of sun exposure for new cars:

Items containing compressed gas or lithium batteries are prone to explosion or combustion under high temperatures. If occupants remain in the vehicle during such incidents, unpredictable harm may occur. Such items include lighters commonly used by gentlemen, hydrating sprays frequently carried by ladies, cooling sprays often used in summer, as well as power banks. These items are best stored in the glove compartment or other areas avoiding direct sunlight – though ideally not kept in the car at all.

New car maintenance:

Whenever possible, park your vehicle in a garage. Avoid parking in strong sunlight to minimise exposure, and reduce rain contact. When parking elsewhere, refrain from haphazard parking that obstructs others, as this may lead to malicious scratches on your car's paintwork.

Exposing new cars to sunlight is generally safe in moderation, but prolonged exposure can cause damage over time. UV rays degrade paint, fade interiors, and weaken rubber seals. Modern cars have UV-resistant coatings, but consistent sun exposure accelerates wear.

To protect your car:

1. Park in shaded areas or use a car cover when possible.
2. Apply a high-quality wax or ceramic coating to protect the paint.
3. Use sunshades for the windscreen to reduce interior heat and UV damage.
4. Condition leather and plastic surfaces regularly to prevent cracking.

While occasional sunlight won’t harm your car, long-term exposure without protection can lead to costly repairs. Models with darker paint, like a BMW iX or Tesla Model 3, may show fading more quickly.

From a detailing perspective, sunlight is a car’s enemy. UV rays break down paint polymers, causing oxidation and fading. Darker colours, such as deep blues or blacks, are especially vulnerable. Even modern clear coats degrade over time. For optimal preservation, park in garages or use UV-protectant products. A ceramic coating adds an extra layer of defence.
