Charging speed reduced
High temperature
detected by Mobile
Connector
High temperature detected by Mobile
Connector alerts indicate the outlet used to
charge is becoming too warm, so charging
has been slowed to protect the outlet.
This is not typically an issue with your vehicle
or your Mobile Connector, but rather an issue
with the outlet. A warm outlet may be caused
by a plug that is not fully inserted, a loose
building wiring connection to the outlet, or an
outlet that is beginning to wear out.
To regain normal charge speed, make sure
your adapter is fully plugged into the outlet. If
charging speed does not return to normal,
contact an electrician to inspect the outlet
and building wiring connections to the outlet
and complete any repairs needed.
If the outlet is worn, it should be replaced
with a high-quality outlet. Consider upgrading
to a Tesla Wall Connector for greater
convenience and highest charging speed.

12V battery must be
replaced soon
Software updates will not
complete until serviced
The 12V battery has aged or degraded and
needs to be replaced. Until the battery is
replaced, vehicle software updates will not
complete.
It is recommended to replace the battery at
your earliest convenience. In the meantime,
continue normal use of the vehicle.
The vehicle is still OK to drive with this alert
present, for a period of time. However, if you
continually delay the 12V battery
replacement, the vehicle may eventually not
have enough power to start or restart.
If the 12V battery is too low to turn on the
vehicle or open the doors, follow the
instructions in Jump Starting the 12V Battery
on page 237.
