Charging stopped - Power lost while charging
Check power source and charging equipment
Power has been lost during charging. This could result from the charging equipment losing power from the source
(for example, a wall outlet) or from an issue with the charging equipment.
This alert is often accompanied by other alerts that can help you identify and troubleshoot the issue. Start by
investigating any other displayed alerts that relate to charging issues.
Alternatively, you can check Mobile Connector or Wall Connector status lights to confirm power to the device, and
also refer to the product owner
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:
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:
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.
(UMC_a017)
Charge rate reduced - Wall plug temperature high
Wall outlet and wiring inspection recommended
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.

Electrical system power reduced
Vehicle may shut down unexpectedly
The electrical system cannot maintain the voltage required to support all vehicle features.
If this alert is present while you are driving, it is possible your vehicle will shut down unexpectedly.
It is also possible that your vehicle will not restart after the current drive.
It is recommended that you eliminate or reduce your use of any non-essential features. This can help your vehicle maintain adequate electrical power for essential functions. It may also prevent your vehicle from shutting down
before you reach your immediate destination, although this is not guaranteed.
If this alert remains active, schedule service immediately. Without service, your vehicle may shut down unexpectedly
or may not restart.

12V battery must be replaced - Schedule service
Software will not update until battery is replaced
The 12V battery is showing degraded performance and needs to be replaced. Until the 12V battery is replaced,
vehicle software updates will not complete.
It is recommended that you have the 12V battery replaced at your earliest convenient opportunity.
You can schedule service via the Tesla Mobile App, or with an independent service provider that offers 12V battery
replacement for your vehicle. Please note that independent service provider options may vary, based on your vehicle
configuration and your location.
Your vehicle is OK to drive with this alert present. However, if you delay the 12V battery replacement, your vehicle
may eventually not have enough power to start or to restart after a recent drive.
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 199.
For more information on the battery system, see Battery Information on page 158.
