How UV Exposure Can Harm Your Car

sun shining inside carWhile ultraviolet light doesn’t always cause immediate damage like a sunburn, it can slowly harm your car over time. Prolonged exposure to the sun’s rays 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 to between 145 and 195 degrees Fahrenheit. Over time, this intense heat can lead to visible signs of wear, such as cracks, fading, and discoloration on your dashboard, upholstery, paint, and other hidden parts of your vehicle.

Dashboard

The dashboard is one of the first areas affected by UV exposure. Located directly under the windshield, it's constantly exposed to harsh sunlight. Fading and cracking are common issues, not only affecting the appearance but also potentially weakening the structure of the material over time.

Upholstery

The type of material used in your car’s seats plays a big role in how much UV damage they suffer. Leather seats, for example, can become dry, stiff, and uncomfortable if left in the sun without protection. The natural oils in leather can be stripped away, leading to long-term discomfort and reduced lifespan.

If you have fabric seats, they too can fade over time due to constant exposure. While they may not crack as easily as leather, the color will eventually dull, making your interior look older than it really is. Regular conditioning and protective measures are essential for maintaining the quality of your seats.

Paint

UV exposure can take a toll on your car’s paint job, especially if you drive a dark-colored vehicle. The paint may lose its shine and develop a faded look due to oxidation. In addition to fading, plastic parts like bumpers, headlights, and mirror covers can also become brittle and develop cracks over time.

This kind of damage can make your car appear older, even if you keep it clean and well-maintained. Protecting your car from the sun is an important step in preserving its value and appearance.

Interior Components

Extreme heat and UV exposure can impact more than just the visual aspects of your car. They can affect the performance and safety of critical components:

  • Belts and hoses may start to crack or fray, which can lead to mechanical failures.
  • Fluids like engine oil, transmission fluid, and antifreeze can evaporate or thicken, reducing their effectiveness and potentially causing overheating or component failure.
  • Heat can also affect tire pressure, increasing the risk of blowouts if tires are overinflated.

Reducing UV Exposure

To protect your car from UV damage, try to park in a garage whenever possible. If that's not an option, use a portable shade or a sunshade to block direct sunlight. Keeping your car out of the sun can help maintain its condition and make it feel cooler when you get in.

In addition to parking strategies, consider these maintenance tips:

  • Regularly wash your car to remove dirt, bird droppings, and road grime that can stick to the surface and cause damage over time.
  • Dry your car with a microfiber cloth after washing to prevent water spots and mineral buildup on the paint.
  • Apply wax regularly to protect the finish and reduce fading, chipping, and rust.
  • If you can't find shade, use a windshield sunshade and slightly open the windows to let heat escape.
  • Use seat covers to protect leather or fabric seats from UV damage, especially if you often park in sunny areas.
