Tesla Model S Charger Will Not Start a Session
You plugged in your Model S and nothing is happening. No green light on the charge port, no animation on the 17-inch touchscreen, just silence. Whether you are at a Supercharger, a third-party CCS2 station, or a home wallbox, there are a handful of common reasons the session will not begin.
Quick Diagnosis
Is the charger screen on and showing a ready state?
Check if the charger display is lit and showing "Available" or a similar ready message.
Symptoms
- Charge port LED stays white or flashes red after plugging in the connector
- 17-inch touchscreen shows no charging animation or displays an error message
- Supercharger stall makes a click but does not begin delivering power
- CCS2 connector at a third-party station locks in but charging never starts
- Tesla app shows 'Not Charging' even though the cable is connected
Why This Happens
Charge port latch not fully engaged
The Model S charge port is on the left rear. If the CCS2 connector is not pushed in firmly until you hear a click, the latch will not engage and the car will not start a session. Rain, ice, or debris in the port can also prevent a clean connection.
Charge port frozen or stuck
In cold weather, the charge port door or the latch mechanism can freeze. The Model S has a charge port heater, but it only activates during preconditioning. If you did not precondition, the latch may not release or engage properly.
Supercharger stall is faulted
Individual Supercharger stalls can go offline while the rest of the station works fine. The stall may appear available but have a hardware issue. Tesla does not always mark faulted stalls in the nav.
Third-party charger authorization failed
At non-Tesla CCS2 chargers, you need to authorize the session through the charger operator's app, RFID card, or contactless payment. Plug & Charge may not be supported at every station. If the charger is waiting for authorization, plugging in alone will not start charging.
Scheduled charging is active
The Model S has a scheduled charging feature that delays charging until a set time (often for off-peak electricity rates). If scheduled charging is on, the car will connect but not draw power until the scheduled time. Check this on the touchscreen under Controls, then Charging.
What to Do
- 1
Check the charge port LED color
Walk to the left rear of the car and look at the charge port light. White means ready but not connected. Blue means communicating. Green means charging. Red or amber means there is a fault. If it is white with the cable plugged in, remove and reseat the connector firmly.
- 2
Unplug and replug the connector
Remove the connector completely, wait five seconds, then reinsert it until you hear the latch click. On CCS2 connectors, make sure both the top (AC pins) and bottom (DC pins) sections are seated properly.

Check for scheduled charging on the touchscreen
On the 17-inch touchscreen, go to Controls, then Charging. If scheduled charging is active, you will see the planned start time. Tap to disable it or select 'Charge Now' to override the schedule.

Authorize the session at non-Tesla chargers
At third-party CCS2 stations, check whether the charger requires you to start the session through an app, RFID card, or contactless payment. Plug & Charge works at supported stations, but many still require manual authorization.
- 5
Try a different stall or charger
If you are at a Supercharger, move to a different stall. If you are at a third-party station, try the other connector. A faulted charger looks identical to a working one from the outside.

Restart the touchscreen
Hold both scroll wheels on the steering wheel for about 10 seconds until the 17-inch touchscreen goes black and reboots. This resets the charging controller and fixes some communication glitches. The car stays on during the reboot.
Prevention Tips
- Precondition the car before charging in cold weather by using Tesla nav to route to the charger at least 20 minutes before arrival
- Keep the charge port clean and free of debris, especially in winter when salt and grime can build up
- At Superchargers, check the Tesla app for real-time stall availability before pulling in
- Carry at least two payment methods for third-party chargers: an RFID card and a bank card for contactless
- Disable scheduled charging when you need to charge immediately at public stations
