How to Fix Error Code CC_a044
-
Stop Charging and Inspect the Adapter Connection
Do not touch exposed pins with wet hands. Always handle the charging cable by the grip, never by the cable itself. -
Check the Power Source (Outlet or Charging Station)
Do not attempt to open or service your home electrical panel unless you are a qualified electrician. Electrical panels carry lethal voltage. -
Try a Different Adapter or Cable
Only use adapters and cables certified for use with Tesla vehicles. Using uncertified or damaged third-party equipment can cause permanent damage to your vehicle's charge port. -
Reboot the Tesla Touchscreen
-
Inspect the Charge Port for Damage or Debris
Never insert metal objects into the charge port. Do not attempt to charge if you see moisture inside the port — allow it to dry completely first. -
Check for Tesla Software Updates
-
Schedule a Tesla Service Appointment If the Error Persists

When to Call a Professional
Contact Tesla Service (via the app or 1-877-79-TESLA) if: the charge port has visibly bent or burned pins, the error persists after trying multiple adapters and power sources, your home 240V EV circuit keeps tripping the breaker, or if the car refuses to charge at a Supercharger as well as at home. Charge port assembly repairs and onboard charger replacements must be performed by Tesla-certified technicians. For electrical panel or dedicated EV circuit issues at home, hire a licensed electrician.Frequently Asked Questions
What does Tesla error code CC_a044 mean?
CC_a044 means Tesla's charging system detected a loss of power on the charging adapter and stopped the charging session for safety. It usually indicates a loose connection, a faulty adapter, a power supply problem, or an issue with the charge port itself.
Can I still drive my Tesla after seeing CC_a044?
Yes, in most cases you can still drive your Tesla normally after this error. The error only affects the charging system. However, if your battery is low and you cannot resolve the charging issue, limit driving until you can charge at a different location such as a Tesla Supercharger.
Will Tesla CC_a044 go away on its own?
Sometimes CC_a044 is caused by a temporary power fluctuation and will clear after you unplug and re-plug the adapter. If it reappears consistently, there is likely an underlying hardware or electrical issue that needs to be addressed.
Is CC_a044 covered under Tesla warranty?
If the root cause is a defective charge port, onboard charger, or factory-supplied Mobile Connector, and your vehicle is within the Tesla Basic Vehicle Limited Warranty (typically 4 years or 50,000 miles), the repair may be covered. Contact Tesla Service to have the issue diagnosed and confirm warranty eligibility.
How do I prevent CC_a044 from happening again?
To reduce the likelihood of this error: always insert and remove the charging adapter firmly and straight; store your Mobile Connector properly to avoid cable damage; keep the charge port free of moisture and debris; have a licensed electrician verify your home EV charging circuit meets Tesla's specifications; and keep your vehicle software up to date.
