What Causes a Sudden Burning Smell Inside the Car?

[KadenLee]

The reasons for a sudden burning smell inside the car are as follows: 1. Overheated wires or electrical short circuits: If it's a plastic-like burning smell, it's mostly caused by overheated electrical wiring. Burnt wires are usually accompanied by localized heating or smoking. With careful inspection, you can locate the source and identify the faulty part. If the wires are overheated, you must stop immediately to find the cause. Although the smell of burnt wires isn't strong, the risk is very high. If not detected promptly, it can easily lead to circuit damage, engine cylinder scuffing, or even the entire vehicle catching fire. 2. Malfunction of rubber components like tires or belts: Check if any belts in the engine compartment are loose or slipping. When the vehicle is running at high speed, belt slippage can cause issues like poor cooling. In such cases, immediate inspection is necessary. If the belt is loose and emits a burning smell, it should be sent for repair right away. Also, check if the brake pads and tires are overheating. Heavy braking during turns or on slopes can easily overload the tires. When there's such a smell from the brakes or tires, it's best to pull over immediately and inspect the brake pads.
