What’s That Burning Smell Coming From My Car?

One day, while driving your car, you notice a strange burning smell. It might be accompanied by heat or even smoke coming from under the hood. A burning odor can signal various issues, some minor and others more serious.

Burning Rubber

If the smell is coming from under the hood, it could be due to a loose hose or belt that has come into contact with a hot part of the engine. If you spot this, try to secure the hose or replace the belt as soon as possible. Another possibility is that the smell is coming from your wheels—this could mean a brake pad is dragging or, if you drive a manual, your clutch might be overheating. If you haven’t been braking hard or climbing hills often, check if the parking brake is still engaged or if the caliper piston is faulty. In some cases, the rubber-like smell may actually be coolant leaking into your heating or air conditioning system, so inspect the radiator for any cracks or leaks.

Burning Oil

A burning oil smell usually means your engine is low on oil or overheating. Check the dipstick and make sure the temperature gauge is working properly. If everything looks okay, there could be an oil leak from the engine block or exhaust system. If exhaust fumes are entering the cabin, you may be breathing in dangerous carbon monoxide—get it checked immediately. Another possibility is a transmission fluid leak, especially if the vacuum modulator is drawing in fluid and sending it into the engine.

Sweet Smell

A sweet, syrupy odor is often a sign that your engine is overheating. Your temperature gauge should alert you, but if it’s not working, the problem might be more serious. Don’t ignore this—it could lead to major engine damage if left unchecked.

Rotten Eggs

This strong, unpleasant smell is usually linked to a faulty catalytic converter. It can also indicate a deeper issue with your engine, such as incorrect fuel mixture or misfiring cylinders. Either way, it's important to get it inspected quickly.

Burnt Toast

If you smell something like burnt toast, it could be an electrical problem—like a short circuit or burning insulation around a wire. This is a serious issue that can worsen while driving, so consider calling for roadside assistance instead of continuing to drive.

Burning Plastic

A plastic-like smell can mean different things. It might be wires, fuses, or connectors in the engine burning. But it could also be something simple like a plastic bag stuck in the engine compartment. Additionally, check your heater system for dust buildup, clogged vents, or antifreeze leaks. If parts of the heater have melted, that’s a sign of a bigger issue.

Smelling Gasoline

If you’re noticing a strong gasoline smell and having trouble starting your car, it could be a flooded engine. The smell might also come from a leak in the fuel injection system, carburetor, or fuel pump. No matter what the cause is, don’t try to fix it yourself without first getting a professional diagnosis.
