About 20-30% of the time that insert a charger into my MS I get a charge error and many times I don't get the error when I'm inserting it but rather late at night when the delayed charging kicks in. . I had my car serviced to a mirror issue and I had the tech check about the charging issue. He said the charging is fine but the plug is not inserted properly. So I figured I would give it another shot and be more careful but too many nights the car is not charging because of the problem and I don't find out until the morning. I have had a Volt for 1 1/2 years and I can't remember a time that I inserted the plug into the car and it didn't charge. Furthermore, I've had the error while plugging into the HWC, at a supercharger and while using the 110 plug. Does anyone else have similar problems?
