Burning Oil Smell from Engine Bay in Tesla Model Y
A burning oil smell from the engine bay of a Tesla Model Y is unusual because electric vehicles have no engine oil. The smell may originate from leaking drive unit oil, brake fluid, or external contaminants like oil from road debris or a nearby vehicle. It could also be from a failing cabin heater or battery thermal management system.
