Causes and Solutions of a Burning Smell in a Vehicle
You would not expect to come across the smell of burning rubber inside the car compartment. But there are many cases in which it happens. Following are some instances in which you might encounter a burning smell in your car.
Slipped Belts under the Hood
It is essential to check the belts under the hood because they could be a reason for the burning smell inside the car.
Belts such as serpentine belts, drive belts, timing belts, and accessory belts usually rotate at high speed and have rubber surfaces, making them prone to wear and tear.

Moreover, when these belts get loose and slip over the pulley, heat is created, which in turn causes a burning rubber smell inside your car. This issue can be resolved by tightening the belt or changing the belt if it is required so [1].
Melting or Loose Hose
A loose hose can be a real nuisance. It can cause a burning rubber smell inside the car and make driving difficult [2]. In most cases, a flexible hose is caused by a loose clamp. When the loose rubber hoses get exposed to high temperatures, they may emit a burning rubber smell. It is because the material used in these hoses is sensitive to heat and can cause an unpleasant odor when it reaches a specific temperature.
The first thing you should do is check if there’s a leak in the hose. If you find any, you must replace the entire hose [3]. However, if there isn’t any, you can tighten the loose hose and protect it from exposure to high-temperature engine components such as the exhaust manifold.

Neglecting the smell caused by the loose, burning hose may result in severe engine damage.
Electrical Short-Circuits
A short circuit is an electrical problem that occurs when the flow of electricity is interrupted, causing a current to pass across an unintended path. For example, it can happen when a wire or other electrical conductor becomes damaged and separates from the point at which it is intended to connect. In the event of short-circuit, a spark erupts, which results in the burning of wire, insulation, and other components. Due to the said burning, you may notice a burning smell in your car.
If you experience this issue, it is best to contact an electrician to ensure your car’s wiring is safe and secure.

Negligence in the severe case of an electrical short circuit may even result in an unwanted situation like burning a vehicle.
Leaking Engine Oil
Oil leaks may be caused by worn seals or gaskets, loose bolts, or a leak in the engine or its oil filter. Leaking oil sometimes drips on the components, such as the exhaust pipe and manifold. These components are typically boiling while the engine is on. When the oil drips on these hot parts of the car, it gets burnt. The burning of this oil causes a burning rubber smell in the car.
Oil leaks can be fixed relatively easily; however, it all depends upon the nature and cause of the leak.
Worn out Clutch
This is a common problem that many car owners have experienced. The car clutch system engages and disengages the engine from the transmission, allowing you to change gears. When this system wears out, it can cause a burning rubber smell inside your car. In addition, a worn-out clutch may not fully disengage at the end of a shift, which can cause a buildup of heat and friction between the engine and transmission.
If you are experiencing this problem with your car, you should schedule an appointment with a mechanic as soon as possible to get it fixed before it becomes too expensive or causes other issues with your engine.
Faulty Brakes
Some people think brakes themselves may cause a burning rubber smell, but this is not true. Instead, brake pads and shoes cause the odor. When these parts wear out and need to be replaced, they will produce a burning rubber smell when you apply pressure on them with your foot while driving.
