EVSE showing open ground

I bought a 2017 Volt Premier two weeks ago and am having some problems with my EVSE. We own two homes and have had the EVSE refuse to charge at both locations due to open ground. We solved the issue at our main home by replacing the outlet.

At our second home, we have a detached garage that is two years old. The EVSE shows open ground in any outlet we try to use in there. A plug-in tester indicates the outlets are grounded properly. We replaced an outlet in the new garage, since that helped at the other house, but it still does not work. I can run a heavy extension cord to the main house and the EVSE works fine.

Thoughts? Is it possible my EVSE is too sensitive?

UPDATE: I was able to borrow an EVSE from a Ford Fusion Energi and it works just fine in my garage, where I have been having trouble with my Volt's EVSE. Do I have a case at the dealer to get a replacement EVSE?
The Volt's EVSE is covered under the Voltec warranty. If the dealership won't help, you could try contacting Chevy directly.
