1. Oil leak
An engine oil leak can cause burning smell in Subaru Impreza, particularly when oil drips onto the exhaust system. The surface temperature of exhaust pipe or manifold can cross 800 degrees Fahrenheit (426 °C) under normal driving behavior.
2. Coolant or other fluid leak
Subaru Impreza needs multiple type of fluids like coolant and brake fluid that are vital for the normal operation of the vehicle. Any leaking fluid that drips onto the exhaust system or hot parts of the engine will burn off and produce burning smell.
3. Bad blower motor or resistor
If the burning smell comes from the air vents when you turn on the AC in your Subaru Impreza, it could be due to overheating blower motor or its resistor. In rare cases, if the blower motor heats up too much, it can even melt the housing and produce burning plastic odor. You may also see white smoke coming out of the AC vents.
4. Burning electrical components
A malfunctioning electrical component or a short in a wire can cause burning smell in Subaru Impreza. Start by inspecting the fuse box in the engine compartment and in the dashboard. Even if the fuses look normal, there could be damage from overheating hidden under the fuses. Hold your nose close to the fuse box and give a good whiff.
5. Exhaust leak
If the burning smell in Impreza resemble exhaust fumes, it could be due to a leaking exhaust manifold. The most prominent sign of a leaking exhaust manifold is loud engine noise from under the hood. You may also smell exhaust when standing over your engine compartment if the leak is large enough.
