Why is there a buzzing sound in the front of a Tesla after turning it off?

This is a normal phenomenon designed to prevent the engine from "seizing up" due to rapid cooling after shutdown. Relevant explanations are as follows: 1. Engine Seizure: After driving for a period, various engine components reach high temperatures. If the car is parked immediately, parts like the cylinder and piston rings or the crankshaft and connecting rods may "stick" together due to the high heat. Upon the next startup, this can lead to a condition commonly referred to as "engine seizure or bearing failure." Therefore, after prolonged driving, it is recommended to let the car idle for a few minutes before shutting it off to allow the engine temperature to decrease naturally. 2. Automatic Cooling Function: The vehicle is equipped with an automatic cooling function. If the engine temperature remains high after parking, the system will automatically activate the fan to continue cooling the engine until the temperature drops to a reasonable level, at which point the fan will stop. This is a normal occurrence.
