I experience different things while the card is parked over several days. Because this car is new I would like to know if this is normal. The car is parked over several days and when I pass the car is see: 1 -Noise coming from the front of the car, charging port light solid green, and dash says car of fully charged. 2 - No noise, dash says car is fully charged, charging port light is off. 3 - No noise for car, charging port solid green, dash says fully charged. 4 - No noise, charging port light off, dash off (this is what I would expect to see most often but it is NOT). Is this normal as I rarely see condition 4.
