What this alert means:
Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot monitor the wall plug adapter temperature, charge current is automatically reduced to 8A.
What to do:
- Unplug your Mobile Connector, including the wall plug adapter, completely from the wall outlet.
- Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.
- Disconnect the wall plug adapter completely from the main body of your Mobile Connector.
- Fully reinsert the wall plug adapter into the main body of your Mobile Connector by pushing it into the socket until it snaps into place.
- Try charging again by plugging the Mobile Connector, including wall plug adapter, fully into the wall outlet.
- If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully connected to your Mobile Connector).
- If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
- If the alert persists, the issue is likely with your Mobile Connector.
If needed, obtain another wall plug adapter or Mobile Connector.
In the meantime, you can continue to charge with the same equipment. The charge rate will be reduced, as charge current will be limited to 8A while this condition persists.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can be located through the map on your vehicle's touchscreen display. See Maps and Navigation for more details.

What this alert means:
Charge current has been temporarily reduced because the Mobile Connector has detected increased temperature inside its control box housing.
What to do:
Make sure the Mobile Connector is not covered by anything, and that there is no heat source nearby. If the problem persists in normal ambient temperatures (under 100°F or 38°C), service is required.

What this alert means:
High temperature detected by Mobile Connector alerts indicate the outlet used to charge is becoming too warm, so charging has been slowed to protect the outlet.
This is not typically an issue with your vehicle or your Mobile Connector, but rather an issue with the outlet. A warm outlet may be caused by a plug that is not fully inserted, a loose building wiring connection to the outlet, or an outlet that is beginning to wear out.
What to do:
Make sure your adapter is fully plugged into the outlet. If charging speed does not return to normal, contact an electrician to inspect the outlet and building wiring connections to the outlet and complete any repairs needed.
If the outlet is worn, it should be replaced with a high-quality outlet. Consider upgrading to a Tesla Wall Connector for greater convenience and highest charging speed.
What this alert means:
Charge current has been temporarily reduced because the Mobile Connector has detected increased temperature in the charge handle that connects to your vehicle's charge port.
What to do:
Make sure the Mobile Connector is fully inserted into your vehicle's charge port inlet.
Inspect the charge port inlet and the Mobile Connector handle for any obstructions or moisture. Make sure any obstruction in the charge port or Mobile Connector handle has been removed and any moisture has been allowed to dry, then try re-inserting the Mobile Connector handle into the charge port.
Also make sure the charge handle of the Mobile Connector is not covered by anything, and that there is no heat source nearby.
If the alert persists in normal ambient temperatures (under 100°F or 38°C), and occurs during multiple charging attempts, this may indicate a condition affecting the Mobile Connector or your vehicle. It is recommended that you schedule service at your convenience.

What this alert means:
Charge current has been reduced because the Mobile Connector has detected a high temperature at the connection between the wall plug adapter and the control box.
What to do:
Make sure the wall plug adapter is fully connected to the Mobile Connector control box.
After unplugging from the power source (wall outlet), inspect the wall plug adapter connection and the Mobile Connector control box connection for any obstructions or moisture.
It is recommended that any debris / foreign objects be removed. Make sure any obstruction has been removed and any moisture has been allowed to dry, then try re-inserting the wall plug adapter into the Mobile Connector and then connecting to the power source (wall outlet).
Also make sure the wall plug adapter is not covered by anything, and that there is no heat source nearby.

What this alert means:
The Mobile Connector has detected an insufficient ground connection of the used electrical outlet. This does not indicate an issue with your Mobile Connector or vehicle but rather likely points to an issue with the electrical installation the Mobile Connector is connected to.
What to do:
Your electrician should ensure there is proper grounding at your circuit breaker or power distribution box and also ensure that appropriate connections are made to the outlet used to connect the Mobile Connector.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can be located through the map on your vehicle's touchscreen display. See Getting Maximum Range for more details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.

What this alert means:
The electrical system cannot maintain the voltage required to support all vehicle features.
If this alert is present while you are driving, it is possible your vehicle will shut down unexpectedly.
If this alert is present when your vehicle is in Park or when it first wakes, it is possible your vehicle may not have adequate electrical power to start driving. A separate vehicle alert may be present to indicate that condition.
What to do:
It is recommended that you eliminate or reduce your use of any non-essential features. This can help your vehicle maintain adequate electrical power for essential functions.
If this alert remains active, schedule service immediately. Without service, your vehicle may shut down unexpectedly or may not restart.
What this alert means:
The low voltage battery is showing degraded performance and needs to be replaced. Until the low voltage battery is replaced, vehicle software updates will not complete.
What to do:
It is recommended that you have the low voltage battery replaced at your earliest convenient opportunity.
You can schedule service via your Tesla Mobile App, or with an independent service provider that offers low voltage battery replacement for your vehicle. Please note that independent service provider options may vary, based on your vehicle configuration and your location.
If the low voltage battery does not have enough electrical power to turn on your vehicle or open the doors, follow the instructions in If Vehicle Has No Power.
For more information on the battery system, see High Voltage Battery Information.
