Fixing a cigarette burn in your car's interior is absolutely doable, and the best method depends on the severity of the burn and the material (fabric or leather). For small burns on fabric seats, a patch repair kit is the most effective and permanent solution. For leather, a leather repair compound can fill and color-match the damage. If the burn is severe and has damaged the cushion underneath, professional repair or seat replacement might be necessary.
The first step is always to assess the damage. Gently clean the area around the burn with a mild upholstery cleaner to remove any ash or debris. For a small, superficial burn on cloth upholstery where the foam cushion isn't damaged, a patch kit is your best bet. These kits involve carefully trimming away the burned fibers, cutting a patch from a spare piece of material (often from under the seat or in a trunk), and bonding it in place with strong fabric adhesive. The key is to feather the edges of the existing material for a seamless look.
For leather or vinyl seats, the process involves filling the burn. After cleaning, you’ll use a leather repair compound to fill the depression. This material needs to be smoothed and leveled with the surrounding surface. Once it cures, you use included color-matched dyes to blend the repair into the rest of the seat. This requires a bit of artistry to match the grain and color perfectly.
If the burn has charred and melted a large area or you're not comfortable with a DIY approach, seeking a professional auto upholstery shop is the wisest choice. They have the tools, materials, and expertise to make the repair virtually invisible.

If it's a tiny burn on the cloth part of your seat, you can sometimes get away with a simple fix. First, use fine-grit sandpaper to gently sand away the burned, crunchy fibers. Then, take a sharp razor blade and carefully "fluff" the surrounding good fibers over the sanded spot. It won't be perfect, but from a distance, it'll blend in much better than a black hole. This is a quick trick, not a permanent repair.

I've sold used cars for years, and fixing minor interior flaws is part of the job. For cigarette burns, your cheapest and easiest solution is a high-quality seat cover. You can get a set that fits your specific car model for under a hundred bucks. It completely covers the damage and protects the seat from future wear. It's not a repair, but it's the most cost-effective way to make the interior look presentable again, especially if you're to sell the car soon.

My dad taught me this one for our old truck's vinyl bench seat. For a small burn, melt a matching color wax crayon into the hole. Let it cool, then shave it flush with a razor blade. It sounds crazy, but it works for a temporary, low-cost fix. It won't hold up to heavy use or heat, but it'll make the burn less noticeable until you can get a proper repair done. Just make sure the wax color is a very close match.

Dealing with a burn on a leather seat requires a different approach. The goal is to fill the void and match the color. You'll need a leather repair kit. Clean the area thoroughly, then apply the flexible filler compound into the burn, slightly overfilling it. Use the included graining paper to stamp a pattern that mimics the original leather grain after it sets. Once it's fully cured, you carefully apply the color dye with a small brush, blending it outward. It takes patience, but a good color match can make the repair nearly invisible.
