What causes a sudden burning smell inside the car?

If there is a plastic burning smell in the cabin, it is usually caused by overheated wires or a short circuit in electrical components; if it is a rubber burning smell, it is usually due to a malfunction in rubber parts such as tires or belts. The reasons for a sudden burning smell inside the car are as follows: 1. Overheated wires or a short circuit in electrical components: If you smell a burning plastic odor, it is caused by overheated electrical wiring. Burning wires are usually accompanied by localized heating or smoke. If wires are overheating, you must stop immediately to identify the cause. Although the smell of burning wires may not be strong, the risk is very high. Failure to detect it promptly can easily lead to circuit damage, engine seizure, or even vehicle self-ignition. 2. Malfunction in rubber parts such as tires or belts: The smell of burning rubber is the easiest to identify. Pay attention to the following areas: (1) Check whether the belts in the engine compartment are loose or slipping. If the belts slip during high-speed operation, it may cause cooling issues. In such cases, immediate inspection is required. If the belts are loose and emitting a burning smell, they should be sent for repair immediately. (2) Check whether the brake pads and tires are overheating. When driving on continuous mountain roads, heavy braking during turns or slopes can easily overload the braking system and tires. If the brakes or tires emit this smell, it is best to pull over immediately and wait for the brake pads to cool down naturally before driving again. Do not pour cold water on the brake pads. Additionally, overheated rubber hoses can also emit a rubber smell.
