Tesla MODEL 3 2022 Owner's Manual page 243

When this assist function activates, you may feel the brake pedal pull away from your foot and notice a strong
increase in brake pressure. You may also hear a pumping sound coming from the brake hydraulic unit at the front of
the vehicle. This will usually last for a few seconds, depending on road surface and vehicle speed. This is completely
normal and does not indicate any issue with your vehicle.
Reduced braking performance is usually temporary, and can occur for a number of reasons including high brake
temperatures after heavy brake use, or driving in extremely cold or wet conditions. It can also indicate that your
brake pads or rotors have worn to the point that normal replacement is needed.
If you continue to experience reduced braking performance which does not improve over time, please contact Tesla
service at your convenience for a brake inspection.

Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
Charging has stopped due to a condition that prevents your vehicle from charging with AC power. DC fast charging /
Supercharging should still function as expected.
This condition could occur due to power supply disturbances caused by the external charging equipment or by the
electrical power grid. In some cases, this condition can even result from turning on nearby electric devices that draw
a lot of power.
If these possible causes can be ruled out, then a condition with your vehicle itself may also be affecting AC charging.
This alert may be accompanied by another alert that specifies the condition affecting AC charging. If so, it is
recommended you start by investigating that alert.
Further troubleshooting tips based on equipment type:
• If using a Mobile Connector, try charging your vehicle with a different wall outlet.
◦ If your vehicle starts to charge and continues to charge as expected, the issue was likely with the original wall
outlet. It is recommended that you contact an electrician to inspect the building wiring connection to that
outlet.
◦ If your vehicle still does not start to charge, or does not continue to charge as expected, the issue may be with
the Mobile Connector or the electrical grid.
• If using a Wall Connector, try charging your vehicle with different charging equipment like a Mobile Connector
powered by a separate wall outlet.
◦ If your vehicle starts to charge and continues to charge as expected, 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 different wall outlets.
• 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.
If this alert persists when attempting to charge at multiple locations and with different charging equipment, it is
recommended that you schedule service.
