Why are you asking the forum? Maybe the EVSE is back ordered. What did the Chevrolet dealership's Service Manager tell you? The dealer should have provided you with a loaner EVSE until they receive the replacement EVSE for your Volt.My dealer determined that the wall charger that came with my Volt was bad. That was a month ago and it hasn't come in yet.
Why does it take so long?
Why don't they take one from a car on the lot?
