A burning smell sometimes comes from oil leaks on the hot part of the vehicle’s engine or in the exhaust. It also could be brake pads that don’t retract when the brake is being released or either because of an aggressive brake.

For a manual transmission vehicle, the clutch could be overheated from the clutch pedal.


If there is a sweet and syrupy odor inside the car means there is a leak in the cooling system.

The source is sometimes difficult to find. The leak comes in the form of steam which produces a smell and may be the cause of fogging windows. Address this problem immediately because it is not good to breathe the antifreeze.


If the musty smell comes from the vents, then the air-conditioning system has molds or mildew. The moisture in the vehicle is collected from the dashboard to the vent. It may harbor mold and dirt. Try running your car’s AC on a fan or high speed so it may clear the mildew and dry the evaporator.

However, there is no guarantee that this won’t happen again, especially if the smell is from the clogged tube which allows the water to get rid of the car. The musty smell is also caused by wet carpets from the water leaks.
