Burning Oil Smell from Engine Bay - Tesla Model 3 2020
A burning oil smell from the engine bay of a Tesla Model 3 is unusual since it is an electric vehicle. This could indicate an oil leak from a component such as the drive unit, a coolant leak (which can smell similar), or debris burning on hot components. Immediate inspection is recommended to prevent damage or fire risk.
Diagnosis Details
Possible Causes
Drive unit oil leak - The drive unit uses oil for lubrication; a seal failure can cause oil to drip onto hot parts.
Coolant leak - Coolant can produce a sweet, burning smell if it leaks onto hot surfaces.
Debris or plastic on hot components - Road debris or plastic bags melting on the inverter or motor can create a burning odor.
Brake fluid leak - Brake fluid has a distinct smell and can burn if it contacts hot parts.
