Troubleshooting Alerts
Your vehicle's onboard charger is detecting input voltage at the charge port when no power has been requested
from the external charging equipment, which indicates the external charging equipment is not functioning as
expected.
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, or a condition affecting your vehicle itself.
As this alert is usually specific to external charging equipment, 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.

Owner's Manual at Charging & Adapter Product
manufacturer's provided documentation for troubleshooting tips.

Charging slowed - Some AC phases not powered
Check power source and charging equipment
Charging speed has been reduced due to a condition that affects your vehicle's ability to charge with AC power. DC
fast charging / Supercharging should still function as expected.
Your vehicle's onboard charger has detected that one or more power converters is not receiving the necessary AC
input voltage. For example: during three-phase charging, one phase might be missing from the AC input power
provided by the external source. This could occur due to a 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.
