◦ If charging speed is still reduced, the issue may be with the Mobile Connector or the
electrical grid.
• If using a Wall Connector, try charging your vehicle with dierent charging equipment like a
Mobile Connector powered by a separate wall outlet.
◦ If charging speed is no longer reduced, the issue was likely with the Wall Connector.
Contact an electrician to inspect the building wiring connection to the Wall Connector.
They should make sure that all wires are properly connected and torqued according to
the installation guide for the Wall Connector.
As this alert may be present due to external charging equipment and power sources, it is
recommended that you:
•
Try charging with dierent wall outlets.
•
Try charging with multiple, dierent types of charging equipment at dierent locations.
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 on page 152 for more details. Additional third-party charging stations may
also be available in your area to help you to pinpoint the issue.
If this alert persists when attempting to charge at multiple locations and with dierent charging
equipment, it is recommended that you schedule service.
For more information on troubleshooting Mobile Connector or Wall Connector status lights,
refer to the product's Owner's Manual at Charging & Adapter Product Guides. If using other
external charging equipment, refer to the manufacturer's provided documentation for
troubleshooting tips.

Poor electric grid power quality detected
Try dierent charging station or location
Charging speed has been reduced or charging has been interrupted due to a condition that
aects your vehicle’s ability to charge with AC power. DC fast charging / Supercharging should
still function as expected.
The onboard charger in your vehicle has detected power supply disturbances in the electrical
power grid. These disturbances interfere with your vehicle's charging process.
Typical causes of these power supply disturbances include:
• Issues with the building wiring and/or the wall outlet.
•
Issues with the external charging equipment.
• Other large electric devices, such as washing machines or air conditioning units, that
temporarily draw a lot of power or otherwise disturb the electrical power grid.
• External conditions aecting the electrical power grid.
As this alert is usually specific to external charging equipment and power sources, and it does
not typically indicate an issue with your vehicle that can be resolved by scheduling service, it is
recommended that you:
•
Try charging with dierent wall outlets.
