Yeah, it must be burned out as I've never seen it come on. When I plug in, the first 3 quadrants each flash but not the fourth. When I purchased the car in October, I purchased a full bumper 2 bumper Ford factory warranty, so I'm hopeful I can get the ring replaced under warranty. I was hesitant to buy the warranty, then last night I had several error codes flash on the display, "Hill start assist unavailable, Traction control not avail; service Advance Trac." Now I'm relieved I got it. I guess the beast needs to go in for service.
I'm pretty sure my charge is listed as 100% even though it's only for 10 miles. The display shows each time I park/start what percentage of charge remains. If it charges to 10 and I use 5, it says 50% of charge remains. I'm embarrassed to admit that I've never gone online and registered with My Ford Mobile. The dealer mentioned it but didn't explain any benefits of, so I just never got around to it. I'm a procrastinator.
