Tesla Cabin Overheat Protection Not Working (11 Easy Fixes)

Cabin Overheat Protection, one of the excellent climate control features offered to you by Tesla, guarantees interior comfort while you park your vehicle.

But what happens when Tesla cabin overheat protection fails? In this article, I will examine the potential causes and solutions for your Tesla cabin overheat protection to stop working.

Let’s Get Started…!!!

How To Fix Tesla Cabin Overheat Protection Not Working

If your Tesla Cabin Overheat Protection is not working you should first check whether it is enabled in the settings or not. Check your car’s battery level, keep an eye out for software upgrades that can affect the overheating protection, and make sure your car is parked properly to enable the feature. 

Persist further to get more information… 

1. Low Battery Level

Tesla vehicle cabin overheat protection is ineffective when your battery level goes below 20%. 

The mode is not activated even though the interior of the car reaches 105°F due to the battery’s limited internal power.

You must have a constant power flow for the optimal performance and consistent efficiency of this feature. 


To resolve this issue you simply have to recharge your Tesla power battery. You can charge it by using a home charger or a Supercharger near your area. 

when Your Tesla battery starts to recharge and increase its power level from 20%. After that, it can maintain its efficiency and provide you cabin overheating protection with a constant electricity supply. 

2. Sentry Mode

The temperature of your vehicle can be raised by the sentry mode because it could drain more battery. That will result in the malfunction of your Tesla cabin overheat protection system.


To address the problem you have to disable the Sentry mode. You can use your Tesla display screen to turn off the Sentry mode. 

You have to select Controls > Safety or Safety & Security. At the top of this section, you will find the Sentry Mode option. Click on the Off option. 

3. Software Error

If your Tesla Cabin Overheat Protection is not working then there may be a problem with the system’s firmware. In this situation, if a software update is available, you should install it.


To update the software in your Tesla vehicle follow the below-stated steps:

  • First, you have to use the two steering-wheel scroll buttons for about 10 seconds, then wait for the screen to return.
  • Then click on Controls > Software to update the software. 
  • Give time to the update so that it finishes downloading.
  • After that, to install the recent updates, you have to open your Tesla mobile app, and select Software Update > Install/Yes

Sometimes your Tesla cabin overheat protection feature is less compatible with the most recent software of your Tesla vehicle. 

It does not automatically operate or work in these situations, which causes the cabin to overheat. 

That’s why before starting the update you have to make sure that your Tesla model cabin overheat protection is compatible with the recent updates.

4. Feature Inactivated

When you are using any other feature of your Tesla vehicle it may turn off the overheat protection. For instance, if you turn on both Sentry mode and cabin overheat protection an alert will be triggered and you might notice sound and movements. The system will automatically turn off the feature to stop the fan and compressor from sounding the alarm.


To fix the issue you should avoid using other features in combination with the overheating protection. Disable the Sentry mode.

5. Cabin Temperature

You may think that the overheat protection mechanism activates when your car is heated. But actually, it’s not a true impression. 

This is because, although 86°F could seem hot to you, this feature is not activated at that temperature. 

When the cabin exceeds 105°F, the overheat protection activates. 


To resolve the problem you must adjust the temperature in your cabin.

6. External Temperature

The other reason that causes your cabin overheat protection feature to become disabled is the outside temperature which is either too high or too low. 

According to your Tesla Company, the ideal operating range for overheating protection is between 50°F and 105°F. 

When your outside temperature is out of this range cabin overheat protection might not be able to adequately cool or heat the cabin.


Refrain from using the cabin overheat protection feature during non-ideal external temperatures.

7. Sun Contact

The cabin overheat protection in your Tesla vehicle may stop working properly when you leave your car in the sun for an extended duration. 

Sunlight can intensify the heat inside your automobile, making it more difficult for the overheat protection feature to reduce the temperature. 


To escape from such a situation you should try to park your vehicle in a shady place, or use a sunshade to block some of the sunshine.

8. Error in the HVAC System

HVAC (heat ventilation and air conditioning system) is a fan that controls the amount of chilly air in the interior of your Tesla vehicle. 

It is a ductless system that is highly effective and efficient. The filters in your Tesla HVAC system can clean the air and improve its flow. If you have a filthy filter it may result in a damaged fan in your car’s HVAC system.

At this level the overheat protection control becomes inactive and it does not perform. The fan may become defective due to debris blockage in it, and the climate control functionality will not work. 


To clarify the problem you have to clean the clogged fan having dirt and debris. For the best operation of the cabin overheat protection feature of your Tesla vehicle I recommend you to replace the air filter. 

But first, you have to fix any electrical issues with your car’s power circuit. In such cases, it is imperative to replace the non-insulated and damaged wires, which enhances the power flow to your Tesla Model.

To replace the air filters follow the below-stated direction:

  • Switch off the cabin overheat protection system.
  • Take the front passenger floor mat and fully recline the front passenger seat.
  • With the help of a clip-pay tool, you have to release the push clips holding the front passenger. Unplugged the two electrical connectors. Moved the footwell cover to the side.
  • You have to gently pry the right-side panel away from the center console while going from top to bottom.
  • Remove the screws holding the HVAC module. By doing so you can move the cabin filter cover to the side.
  • Fold the tabs of the upper and lower cabin filters inward, respectively.
  • Grab the tab on the upper cabin filter and gently remove the upper filter from the HVAC module.
  • Similarly, you have to pull the lower filter out of the HVAC module by maintaining your grasp on the lower cabin filter.
  • Know you have to insert the lower cabin filter and the upper cabin filter into the HVAC module.
  • To attach the cabin filter cover, fold the tabs inward.
  • You have to install the cabin filter and fasten the T20 screw.
  • Reattach the two electrical connectors to the components. Then cover with a push clip.
  • Firmly secure all the clips.
  • Reinstall the front passenger floor mat and move the front passenger seat back into its old position.

9. User Profile

If you are having an issue with your cabin overheat protection feature it might be due to your user profile.


You should try to delete some or all of their user profiles. To delete the user profile you have to use your Tesla app or the touchscreen of your vehicle.

10. Driving Mode

The cabin overheat protection occasionally does not function when you activate it while in driving mode. With a few limitations, it is a standard setting in your car. 

It works best while you park your vehicle due to its characteristics and performance standards. When you lower the car’s acceleration to activate the feature, it is ineffective.


It is not a mechanical or electrical defect, though, and you may solve it by leaving the car idle for a while. 

When the inside temperature reaches 105°F or greater, the climate control feature may be automatically activated. 

You should avoid activating this feature in your driving mode since it may affect how well the heat control feature works.

11. Tesla Customer Service Center

If nothing works, you can consult your nearby Tesla customer service center and arrange a meeting with them. They will provide you with possible causes and also troubleshoot your problem.
