Understanding the Reasons Behind the Unusual Noises Made by Your Tesla Even When It’s Turned Off

If you’re a proud Tesla owner, you might have noticed some unusual noises coming out of your car even when it’s turned off. While this may seem strange, it’s actually quite common. In fact, many electric cars, including Tesla, make noises when they’re switched off. So, why does this happen? In this article, we’ll be discussing the reasons behind these noises and what you can do to address them.

Noisy Cooling System:

One of the most common reasons why your Tesla might be making noise even when it’s turned off is due to its cooling system. Tesla cars are equipped with a powerful cooling system to regulate the temperature of the battery and keep it within safe limits. This cooling system is responsible for continuously circulating the coolant fluid through the battery and other components like the motor and the inverter. Even when the car is turned off, the cooling system keeps running for a few minutes to dissipate any excess heat. During this cooling-down period, you might hear some gurgling or whining noises coming out of your car.

Electronic Components:

Apart from the cooling system, another reason why your Tesla might be making noise is due to the electronic components. Tesla cars are notoriously complex and rely heavily on their electronic system for their operation. These electronic components include sensors, actuators, and controllers that constantly monitor and regulate the car’s various functions. Even when the car is turned off, some of these electronic components might still be active, producing some faint buzzing or clicking sounds.

Battery Management System:

Another reason why your Tesla may be making noise when turned off is due to the Battery Management System (BMS). The BMS is responsible for monitoring the state of the battery pack, including its temperature, voltage, and current. It’s also responsible for balancing the charge across the individual cells of the battery pack to extend its lifespan. Even when the car is turned off, the BMS might still be active, producing some faint noises.

What Can You Do About It?

While these noises might be concerning, they’re completely normal and nothing to worry about. However, if you find the noise disturbing, there are a few things you can do about it. Firstly, you can park your car away from your bedroom or any other quiet area to minimize the noise level. Alternatively, you can try turning off the “Always Connected” feature in your car’s settings. This feature allows your car to stay connected to Tesla servers even when it’s turned off, which can cause some of the electronic components to stay active. By turning off this feature, you can effectively reduce the noise level.


In conclusion, the noises produced by Tesla cars even when they’re turned off are completely normal and not indicative of any underlying problems. These noises are a result of the complex electronic and mechanical systems that Tesla cars are equipped with. While they might be a bit annoying, they’re nothing to worry about and can be easily minimized. If you have any further concerns, it’s always a good idea to consult your Tesla service center for further advice.
