How to Troubleshoot Tesla Charging Problems?

Seeing a Tesla charging error code can be alarming, but many common charging problems are caused by a loose connection, faulty outlet, overheating, or incorrect wiring—not the Tesla itself.

Before calling an electrician or visiting a Tesla service center, here are some common Tesla charging errors and simple troubleshooting steps.

Tesla CC_A011, CC_A012 & CC_A013: Overheating

Tesla error codes CC_A011, CC_A012, and CC_A013 indicate an overheating issue with the charging equipment or electrical connection.

EVs draw significant power continuously, which can expose problems with an old, loose, damaged, or incorrectly wired outlet. Excessive resistance at the connection can generate heat.

AC WORKS® G2 EV adapters feature built-in temperature sensors that monitor heat and can reduce the charging rate or stop charging when excessive temperature is detected.

If an outlet is overheating, damaged, or showing signs of melting or discoloration, stop using it and have it professionally inspected.

Tesla CC_A010, CC_A014 & CC_A020: Outlet or Wall Connector Problems

CC_A010, CC_A014, and CC_A020 can indicate a problem with the wall connector or electrical outlet.

These issues can be especially noticeable at RV campgrounds, where outlets may be worn from years of use. An outlet that works for an RV may still have problems under the continuous load of EV charging.

If the error repeatedly occurs at one outlet, have the outlet inspected by a qualified electrician.

Tesla CC_A015–CC_A019: Connection Problems

Tesla error codes CC_A015 through CC_A019 are commonly associated with vehicle connection issues.

Try these steps:

1. Disconnect and reconnect the adapter to the Tesla Mobile Connector.

2. Make sure the charging handle is fully inserted into the vehicle.

3. Check the connections for dirt or debris.

4. Inspect the adapter and plug for damage.

5. Make sure the plug prongs are straight.

A connection that is not fully seated can cause charging problems even when everything appears to be plugged in.

Tesla Charging Error FAQ

What Does Tesla CC_A009 Mean?

Tesla CC_A009 can indicate incorrectly wired electrical lines or improper grounding.

If CC_A009 appears after installing a new charging outlet, stop using the outlet and contact a qualified electrician immediately. Incorrect wiring or grounding can create a dangerous electrical condition.

Can Bent Plug Prongs Cause Tesla Charging Errors?

Yes. Bent or misaligned prongs can prevent a proper connection with the outlet. This can increase electrical resistance and generate additional heat.

Always inspect your adapter before charging and do not use equipment with damaged electrical components.

Why does my Tesla stop charging because of overheating?

A Tesla may reduce charging speed or stop charging when excessive heat is detected. A loose, worn, damaged, or improperly wired outlet can create heat during continuous EV charging.

Can a bad outlet cause Tesla charging errors?

Yes. A faulty or poorly maintained outlet can cause charging errors, especially when an EV is drawing power continuously for an extended period.

What should I check if my Tesla won't charge?

Check the error code, charging connections, outlet, adapter, plug prongs, and charging handle. Make sure everything is fully connected and free of dirt or damage.

Should I replace my Tesla adapter if I get an error code?

Not necessarily. A charging error does not automatically mean the adapter is defective. The problem may be the outlet, wiring, or connection.

When should I call an electrician?

Contact a qualified electrician if you notice overheating, burning, melting, damaged outlets, incorrect wiring, grounding problems, or repeated errors from the same outlet.
