Tesla 12V battery low or dead

Likely causes

• Low-voltage battery worn out with age
• Main battery left near empty for a long time
• Car parked for weeks without charging
• Extreme heat or cold

Try this first

• Check the app or screen for a low-voltage battery alert
• If the car still responds, plug it in and keep it charging
• If you're inside and the doors won't open, use the manual release shown in your owner's manual
• Don't pry at the front trunk or force the doors

When to call us

• The screen is black and the doors won't open
• The car won't wake from the app, the phone key or the key card
• You need the car awake so it can go in for service
