Why does tesla make noise when parked 

Hear your Tesla making an odd noise when parked, are you concerned? Well, you’re not alone, so let’s sort out why your Tesla makes noise when parked!

We simply aren’t used to hearing these noises, because, we’ve mostly been trained toward being wary of any odd sounds in our traditional internal combustion engine vehicles.

Key Takeaways:

While most tires on fossil fuel vehicles last an average of 50k-60k miles (about 4 years), tires on electric vehicles don’t last nearly as long and you may need to change them as soon as 15-20K miles.
As a general rule, you should start shopping for new tires one the tread pattern has about 4/32″ of an inch remaining.
While many tires are warranted between 45k-60k miles, electric vehicles like Teslas wear out much faster, meaning replacement can come as soon as 15k miles.

For the last few years, Tesla Model 3 and Tesla Model Y drivers have all been talking about an odd whirring noise emanating from their vehicles while they are parked.

If you own one of the above Teslas or some other variant and have experienced this very same issue, this blog post should serve to clarify any nagging concerns and put an end to any misunderstandings.

The buzzing noises you may notice are just a typical component of how an automobile works.

Common Culprit For a Mystery Noise When Parked

The primary coolant pump is perhaps the most plausible source of the humming you are hearing since it performs routine regulatory tasks to maintain the life of your battery.

This really is one of the main reasons why we may feel so uncomfortable with our EVs.

What distinguishes EVs most significantly from conventional vehicles is their lithium-ion battery system, which has replaced the engine as the major power source for vehicles.

Similar to engines, EV batteries require precise thermoregulation to avoid overheating and deterioration.

The cooling pump could be working as a result to maintain the ideal air temperatures required for the battery to function correctly the next time you start your automobile.

The ideal temperature for your Tesla is 72 degrees Fahrenheit (22 degrees Celsius).

When idle, you will notice the vehicle vibrating for a while as the car is physically working to cool down your car, although it should not be buzzing continually.

But why is it so noticeable?

You wouldn’t have noticed that your Tesla produced any noise at all when parked if the vehicle wasn’t so very quiet.

Because of this electric vehicle’s incredible efficiency, one can even hear the coolant pump’s buzzing sounds amid all that silence.

This is comparable to listening to your vehicle’s fans operate once you have parked and turned off the ignition.

We are used to the fan noise, and it’s reasonable to suppose that, over time, we will also get used to the humming sound of Tesla cars.

Even after Tesla’s rapid spread, ICE continues to be the predominant form of transportation currently.

The standard gas guzzler’s “engine roar” drowns out every other noise, and if a Tesla’s coolant pump was located underneath the hood with an ICE, you would never hear it buzzing.

Often these individuals consider any “weird” sound coming from a vehicle as a sign of trouble and disregard its significance in the operation of the intended system.

Because of our acquaintance with ICE, where any sound detected well above the roar of the engine should certainly signify a severe malfunction.

When To Be Concerned

If something really simple is wrong or because of a human error, then it usually has something to do with the following issues:

  • The automatic climate control of the car is malfunctioning
  • The cabin is overheating
  • The high heat levels of the battery
  • The car was not turned off completely
  • Bluetooth devices are still connected

Note that you can stop the fan of your Tesla from working by switching off the HVAC, switching off climate control, and opening and closing the car doors to “reset” your vehicle.

When to worry over a Serious Malfunction:

If you want to be certain that there isn’t any serious malfunction, then:

1. Assess Tesla’s Activity:

If you are hearing unfamiliar noises, make sure that the vehicle is performing as it should.

For instance, ask yourself the following:

  • Do you feel regenerative braking operating less effectively?
  • Does it seem weird when you steer?
  • Does the autopilot not activate whenever it ought to?
  • Have you experienced a weak or unresponsive accelerator pedal?

It’s a solid guiding principle to recognize when weird noises are followed by a malfunctioning feature. It’s a wise decision to speak with a Tesla service center just in case.

But, if every function is working, you probably don’t need to fret over such noises.

2. Take note of any changes in sound:

If this is your first EV, aim to become accustomed to both the noises that normally occur as well as those that seem a bit out of sync.

The majority of typical noises in a Tesla are predictable in terms of how loud they are and how often they last.

As a result, another thing that is an obvious red flag, like if you heard a sound that varied in volume and timeframe.

3. Talk in an Online Forum

Visit the Tesla discussion sites and YouTube and search for a similar problem there. These are very helpful as it provides both visual and audio support and gives real user experiences.

Countless Tesla supporters and customers frequently produce information that allays any worries concerning unidentified sounds and problems.

If there is an issue, they will also provide you with assistance in solving it. If everything is fine, then there is nothing to worry about.

4. Still Unsure? Go to a Tesla Service Center.

Ultimately, confer with the Tesla service center if, at the conclusion of the above steps, you believe that you still do not know the explanations for your previous problems.

Perhaps even worse, you have far more queries and worries than you originally had at the start. If there is a genuine issue, then they will be able to describe and resolve it.

They may also reassure you that there’s nothing wrong by explaining why it isn’t.


As we’ve previously mentioned, it makes sense that consumers would be worried over such hums, whines, and beeps that appear to come from EVs like Teslas.

In comparison to the vehicles, we have grown accustomed to, this is a whole new category. 

Having these types of questions is very normal as this tech is still in baby stages (oh they grow so fast!) and thats why we have the EV FAQ Page! Give a look for many common electric vehicle common questions.

Since prior generations were reared on internal combustion engines, it should come as no surprise if we can recognize and decipher ICE automobiles’ sounds and functions because we use them as our default.

The truth is, whenever it comes to a Tesla or some other EV, we must acknowledge that we have never owned a vehicle similar to this before and that there are numerous mysteries that come with it.

Therefore, it is completely normal to occasionally worry about your automobile from time to time.
