How UV Exposure Can Harm Your Car

sun shining inside carWhile ultraviolet (UV) light doesn’t always cause immediate harm like a sunburn, it can slowly damage your car over time. Even if you don’t notice the effects right away, prolonged exposure to sunlight and high temperatures can gradually degrade both the interior and exterior of your vehicle.

When parked in direct sunlight, the temperature inside your car can soar between 145 to 195 degrees Fahrenheit. Over time, this heat and UV exposure can lead to visible issues such as cracks, fading, and wear on various parts of your car.

Dashboard

The dashboard is one of the first areas affected by UV rays. Located just below the windshield, it’s constantly exposed to the sun, leading to discoloration, cracking, and even structural weakening. These changes not only affect the look of your car but can also impact its functionality over time.

Upholstery

The type of material used for your car's seats determines how much damage UV rays will cause. Leather seats, for example, can become dry, stiff, and cracked when left in the sun regularly. This loss of natural oils makes them uncomfortable and less durable. It’s important to keep leather conditioned and protected with seat covers if you often park in sunny areas.

Fabric seats are also vulnerable. Though they may not crack as easily, they can fade over time due to constant exposure to UV light. Regular cleaning and protection can help maintain their appearance and longevity.

Paint

UV exposure can significantly affect your car’s paint job, especially if it's dark-colored. The color may fade, and the finish may lose its shine due to oxidation. Plastic components like bumpers, headlights, and mirror covers can also suffer—fading in color and developing cracks over time.

This kind of damage can make your car look older than it is, even if you keep it clean and well-maintained.

Interior Components

Excessive heat and UV exposure can also impact the performance and safety of your vehicle:

  • Belts and hoses may become brittle and eventually break, leading to potential mechanical failure.
  • Fluids such as engine oil, transmission fluid, and antifreeze can evaporate or thicken, affecting their effectiveness and potentially causing overheating or premature wear.
  • Heat can also affect tire pressure, increasing the risk of a blowout if tires are overinflated.

Reducing UV Exposure

To protect your car from UV damage, try to park in shaded areas whenever possible. If you have a garage, use it. Otherwise, consider using a portable car cover or a sunshade for your windshield.

In addition to parking strategies, regular maintenance can go a long way:

  • Wash your car frequently to remove dirt, bird droppings, and road grime that can etch into the paint.
  • Dry your car with a microfiber cloth to prevent water spots and mineral buildup.
  • Apply wax to protect the paint and reduce fading, chipping, and rust.
  • If you can't park in the shade, use a windshield sunshade and slightly open the windows to let heat escape.
  • Use seat covers for leather upholstery to shield it from harmful UV rays.
