Why does my car smell so bad?
If the scent inside your vehicle is more potent compared to the outside, it is possible that the issue may lie within the heater system. Heaters make use of a petite radiator-like component called the "core" to warm the air in the cabin. If you notice dampness in the carpet or excessive fogging on the windows, there is a possibility of a leak in the heater core.
Is there a possibility that your car's coolant is mixing with the cabin air, causing the syrupy smell?
The function of this component is to take warm air from the coolant or antifreeze and deliver it to the passenger cabin. If there happens to be a crack or hole in the heater core, it can result in a leakage of antifreeze which then mixes with the air circulating inside the car. This can lead to the emission of an unpleasant odor.
