What this alert means:

Your vehicle has detected a condition internal to the high voltage battery that is limiting the battery’s performance.

You may notice that your vehicle's top speed is reduced and it responds slower than previously to acceleration requests.

Your vehicle's maximum range may be reduced, and your vehicle may take longer to charge than before. Maximum charge rate varies, as always, based on location, power source, and charging equipment.

Service is required to restore full performance.

What to do:

Your vehicle is OK to drive.

It is recommended that you schedule service at your earliest opportunity. Without service, your vehicle may continue to show reduced power, acceleration, range, and charging performance.

While this alert remains present, keep your vehicle charged to 30% capacity or higher to avoid any discrepancy between the estimated range displayed on your vehicle's touchscreen and the actual high voltage battery charge level.

For more information on the high voltage battery, see High Voltage Battery Information.

What this alert means:

A communication error occurred between the Wall Connector and the vehicle.

What to do:

Try charging again by disconnecting the Wall Connector from the vehicle and reconnecting.

  1. If the issue persists, turn OFF the circuit breaker servicing the Wall Connector, wait 10 seconds, turn the circuit breaker ON again, then try reconnecting the Wall Connector to the vehicle.
  2. If the issue persists and other charging equipment is available, plug the vehicle into another Wall Connector or a Mobile Connector to determine if the vehicle is able to communicate with other charging equipment.
  3. If the issue persists, service is required.

For more information, see the installation guide for your Wall Connector.

What this alert means:

The charge port latch cannot unlatch the charge cable, and cold ambient temperature is detected.

What to do:

To remove any strain on the cable, re-insert the charge cable fully into the charge port inlet. Try again to unlatch the charge cable.

If the charge cable still cannot be removed, the charge port latch may be frozen.

To help thaw any ice on the charge port latch, press the Defrost Car button in your Tesla Mobile App to defrost your vehicle for approximately 30 to 45 minutes.

Informational PurposesAn informational icon, calling your attention
Note
Be sure to use Defrost Car in your Mobile App to defrost your vehicle. Adjusting the climate control settings in your vehicle's touchscreen is not as effective.

It may also be possible to thaw any ice affecting the charge port latch by turning on rear defrost via your vehicle touchscreen. Some vehicles are equipped with a charge port inlet heater that turns on when you turn on the rear defrost in cold weather conditions.

For more information on charging in cold weather conditions, see Cold Weather Best Practices.

If the charge cable still cannot be removed, try the charge port manual releasecable in your vehicle’s trunk.

  1. Make sure your vehicle is not actively charging.
    • On your vehicle touchscreen, access the charging screen.
    • If necessary, press Stop Charging.
  2. Open the rear trunk.
  3. Pull the charge port release cable downwards to unlatch the charge cable.
    • Informational PurposesAn informational icon, calling your attention
      Note
      The release cable is located on the left hand side of the rear trunk. It may be recessed within a small opening of the trunk interior trim.
  4. Pull the charge cable from the charge port.
