I've had my 4xe for about a year with no charging issues to date. Out of the blue, the factory charging cable is not working. I get the green light on the charger brick, but the Wrangler shows the red indicator of a charging issue. I know the power is fine. Any ideas? If the charger was bad, I assume I wouldn't get the green LED light, right? Any ideas out there? Cheapest replacement cable is $200, so that's the last resort.
