This just started with me last week.

I unplug, close the charging door, and start to drive off and within a second or two I get the "Charge Door Open" message on the dash.

Thinking I didn't close it all the way I stop, get out, and look. Nope, it's closed.
Push on it to make sure it's closed all the way. It is, but message persists.

Open the charge door and slap it shut. Error message goes away.

So, anyone know which sensor or switch I need to tackle to make this stop?

Circuit/System Verification
Vehicle in Service Mode, observe the scan tool Charge Port Door parameter while opening and closing the charge port door, the value should change between Open and Closed.

Circuit/System Testing
1. Vehicle OFF, disconnect the harness connector at the B197 charge port door position switch.
2. Test for less than 10 Ω between the ground circuit terminal C and ground. If greater than the specified range, test the ground circuit for an open/high resistance.
3. Vehicle in Service Mode, test for 4.75-5.25 V between the signal circuit terminal A and ground. If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K114B hybrid powertrain control module 2. If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K114B hybrid powertrain control module 2.
4. If all circuits test normal, test or replace the B197 charge port door position switch.

Component Testing
1. Vehicle OFF, disconnect the harness connector at the B197 charge port door position switch.
2. Test for 180 Ω--190 Ω between the signal terminal A and the ground terminal C with the switch in the open position. If not within the specified range, replace the B197 charge port door position switch.
3. Test for 2040 Ω--2065 Ω between the signal terminal A and the ground terminal C with the switch in the closed position. If not within the specified range, replace the B197 charge port door position switch.

I've had this happen a few times in my 2013. You can make it go away by pressing the clear button on the dash on the driver side underneath the driver air vent.

The switch may be the same, but I don't think there's a door actuator (3) in the 2013 model. The above diagram is from the 2012 Volt/Ampera service manual.

Yes, I used to slam mine shut, but I learned that a firm slow close while pushing where the latch engages works 99% of the time.

Follow up

I finally re-did the silicone treatment to keep the door from sticking shut, and at the same time went over all the surfaces with q-tips and compressed air. The issue has not re-occurred since I did that.

Grrrrr... it was good for a while, but here we go again with the "charge door open".
I'm going to try the cleanout and blowout with compressed air again, if that doesn't work I guess I make a service appointment.

What a stupid thing to have to spend money on.

It would seem to be the switch. Is there no way to access it to adjust?

The service manual procedures don't mention any adjustment. I did wonder if dielectric grease might help, but how would one apply it to the switch contacts? Either way you're pulling the switch.

This assumes that the switch is the problem. Somms' post has other culprits listed.

I have been getting this issue more and more lately. Are there any DIY solution to this issue? I'm selling my car in two weeks and want to have this be fixed before the person buying it takes delivery!
