• Try charging with different wall outlets.
• Try charging again (disconnect and reconnect to retry) when other large electric devices are not drawing power.
• Try charging with multiple, different types of charging equipment at different 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
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.

External charging equipment not providing power
Check power source or try different equipment
Charging cannot begin due to a condition that prevents your vehicle from charging with AC power. DC fast
charging / Supercharging should still function as expected.
Your vehicle has requested AC power from the external charging equipment, but the onboard charger does not
detect any supply voltage coming from the equipment.
This can sometimes be caused by a hardware issue specific to the external charging equipment, which prevents the
charging equipment from switching power to the vehicle on or off when requested. It could also occur due to
another condition affecting the external charging equipment, the power source it is connected to, or your vehicle
itself.
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
multiple, different types of charging equipment.
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
details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.

Charge rate reduced - Unexpected voltage drop
Remove extension cords / Have wiring inspected
Charging speed has been reduced because the onboard charger in your vehicle has detected a large voltage drop
during charging.
Likely causes of this issue include:
• Problems with the building wiring and/or the wall outlet.
• An extension cord or other wiring that cannot support the requested charge current.
This issue can also result from turning on electric devices that draw a lot of power from the same branch circuit
while the vehicle is charging.
If this issue has occurred multiple times at your normal charging location, contact an electrician to inspect the
electrical installation. They should check the following:
• Any installed charging equipment and its connection to the building wiring.
