Yesterday morning we found the right light on our SPX charger was flashing red. My wife says she plugged in the Volt like normal last night and got the normal horn sequence saying everything was fine. We unplugged and re-plugged the charger into the Volt and got the red light again. We turned on the Volt and it had no additional charge so the failure must have happened earlier into the 8 hour charging cycle. We power cycled the Volt and then plugged in again and got a normal charge. We hoped it was just a fluke.
This morning the blinking red light returned. We called OnStar to check error codes and none were reported. We have a dealer appointment for Tuesday. In the meantime, anyone have suggestions on what may be wrong?
