We all expect our Teslas to be these perfect creations from heaven that never break or have any faults. Of course, this only happens with Elon’s Tesla, and we peasants have to deal with the daily Tesla problems that do pop up from time to time.
One unfortunate problem is with the charging system and that it often stops for some reason. Like with most phones, the charger can cause issues because of regular use and ware and tare.
In this article, I’ve compiled the 8 most common reasons why your Tesla might stop charging. Some reasons might be out of your control and some might be some minor oversight that you made. In any case, I hope you find this article helpful.
- 1. High Temperatures Outside May Be To Blame

- 3. A Ground Fault Could Be Interrupting the Charge
- 4. A Relay or Contactor Error

1. High Temperatures Outside May Be To Blame
If you were lucky enough to get your hands on a Tesla, you’re probably wondering why your expensive car suddenly stopped charging. Though the company has been touting its cars as resilient machines that can operate in extreme weather conditions, it turns out that high temperatures may cause a charging problem.
The problem seems to be affecting a small number of Tesla owners, and most of them have taken to social media and online forums to complain about the issue. One user on Youtube said that her car stopped charging when the temperature outside reached 95°F (35°C). Here is a link to her video:
How To Fix
The solution is to charge in a cooler area or wait until the temperature drops before attempting to charge again. Tesla has not yet released a statement about the problem, but it is likely working on a fix. In the meantime, owners should keep an eye on the temperature when charging their cars.
|High temperature.||Wait for the temperature to drop/ charge inside.|
|Faulty adapter.||Contact Tesla customer service.|
|Grounding issue.||Call an electrician.|
|Relay/contactor error.||Call Tesla customer service.|
|Over/under voltage.||Wait it out or find plan B.|
|Adapter fault.||Call Tesla.|
|Incorrect pilot level.||Adjust it.|
|Software update.||Call Tesla/wait it out.|
2. A Faulty Adapter Could Also Be the Culprit
It’s also possible that a faulty adapter is to blame for the charging issue. I have experienced this problem firsthand with my Tesla Model S. It was flashing the green light at five intervals, which indicates a problem with the adapter.
I contacted Tesla customer service, and they sent me a new adapter. Once I received it, I plugged it in, and the car started charging again without issues.
How To Fix
If you’re experiencing this problem, I recommend checking your adapter to see if it is damaged or faulty. You can also try using a different adapter to see if that solves the problem.
I also found that a loose connection between the adapter and the car can cause this charging problem. Make sure that the adapter is securely plugged into the vehicle and wall before attempting to charge.
3. A Ground Fault Could Be Interrupting the Charge
A ground fault may be why your Tesla stops charging. This can happen when there is a break in the circuit between the car and the ground.
One way to test for a ground fault is to plug the charger into another outlet. If the problem persists, you are likely looking at a grounding issue. You can also try charging your car from a different location, such as a public charging station.
How To Fix
When a grounding issue occurs, the charger goes off completely, and the vehicle will not start charging again until the ground fault is fixed. The best way to fix a ground fault is to have an electrician come out and repair the problem.
This is one of the least common reasons your Tesla may stop charging, but it is still a possibility. If you have ruled out all of the other potential causes, this may be it.
4. A Relay or Contactor Error
This is another uncommon problem. A relay is an electric switch used to control the flow of electricity, and the contactor is the switch that controls the flow of power to the car.
If either of these components is not working correctly, it can cause charging issues with your Tesla. This problem is most likely to occur if you have recently changed the charger or the adapter.
How To Fix
Unfortunately, a relay or contactor error isn’t something you can fix without expert help. If you think this may be the problem, I recommend contacting Tesla customer service. They will be able to diagnose the problem and send you a new charger or adapter if necessary.
5. The Over or Under Voltage Protection System Is Activated
Your Tesla has an overvoltage protection system that is designed to protect the battery from damage. This system can also prevent your car from charging if the voltage is too high.
How To Fix
The overvoltage system is usually activated when the voltage exceeds a certain threshold, which can happen if the charger is not working correctly or if there is a problem with the power supply.
If you think that this may be the problem, your best bet is to wait out the storm or try charging your car from a different location. Once the power supply is back to normal, your Tesla should start charging again without issues.
6. Adapter Fault
This is another problem that can occur if you have recently changed the charger or the adapter. If either of these components is not working correctly, it can cause charging issues for your Tesla.
How To Fix
Common problems with Tesla adapters include:
- The adapter is not plugged in correctly.
- Damaged or faulty adapter.
- The adapter is not compatible with your Tesla.
If you think the adapter may be the problem, I recommend checking it to see if it is damaged, plugged incorrectly, or faulty. You can also try using a different adapter to see if that solves the problem.

7. Incorrect Pilot Level
The pilot level is a setting on your Tesla that tells the charger how much power to use. If this setting is incorrect, it can cause your Tesla to stop charging.
How To Fix
To fix this problem, you’ll need to adjust the pilot level. Chances are you’ve set the pilot level such that the charger is delivering more power than your car can handle, prompting your Tesla to stop charging as a means of protecting the charging system and other internal components.
Adjusting the pilot level can be done from the touchscreen in your car. Once you have changed it, try charging your vehicle again.
8. Software Update
Sometimes, a software update can cause charging issues on your Tesla. This is most likely to occur if you have recently received an update on your car.
How To Fix
If you think that this may be the problem, I recommend trying to charge your vehicle from a different location. If the problem persists, wait at least 8 hours and try charging your vehicle again.
If that does not work, contact Tesla customer service. They may be able to help you troubleshoot the problem or provide you with a software update.
Tesla Charging FAQs
Having explored some of the potential reasons why your Tesla stops charging, let’s round-up today’s discussion with some FAQs related to today’s topic.
Do Teslas Stop Charging When Full?
Teslas automatically stop charging once the battery is fully charged. However, the car will resume charging if any subsequent activity causes the battery charge to drop.
Can a Tesla Charge Slowly at a Supercharger?
A Tesla can charge at a slower rate than normal at a supercharger when the battery is almost fully charged. Supercharging rates typically drop as the battery approaches full charge.
