My '14 Volt was bought new and now has 48K. It's been charging nightly on a Blink Level 2 home charger for the past 3 years. I've also charged it at public charging stations often. It's been very reliable so far.
So this week, when I plugged in the car to the Blink charger, I expected the car to initiate a charge for 20 seconds, then stop, with the car's charging indicator to flash slowly to indicate "delayed charging."
What I got instead was the car trying to initiate a charge, stop, start again, stop--it never would get to the "delayed charging" phase. Each time it starts and stops, the car honks once. On the dash, I saw a message "Problem Detected with Charging Station," No CEL displayed, and Onstar couldn't detect any error or fault codes.
So thinking that maybe I had a problem with the Blink Charger, I tried using 2 other Level 2 chargers:
a Panasonic portable EVSE (from a '11 Leaf) that was upgraded by EVSEUpgrade to a Level 2, and,
the Clipper Creek portable EVSE (from a '16 Volt) with a 240v adapter.
Both of these chargers also exhibited the same issue--the stop, start, stop... error.
But my '14 Volt charges fine on the supplied Level 1 charger (either on 8 amp or 12 amp). No errors or problems.
And interestingly, all 3 Level 2 chargers work perfectly fine on my 2016 Volt--no errors or problems.
Any ideas why my '14 couldn't charge on Level 2? I'm going to try a public charging station next, so that way I can rule out that possibly something is wrong with my house wiring or utility.
