I was fighting this issue before my battery had to be replaced. After the 4G modem upgrade, the departure times and value charge doesn’t work. I am not sure what the issue is, but I will list some symptoms.
1. Departure time(mygo time) will sync from FordPass to the vehicle, but the car won’t do anything.
2. Value charge shows start Wednesday 757 and end Sunday 1657.
3. When the vehicle is plugged in, the app always shows: will finish Sunday Jan 16 at 1657.
I spoke with Ford on chat and the phone, and they basically conclude that I need to take it to the dealer.
1. Internal modem clock could be messed up, either from sync3 or the modem itself.
2. Bad part.
3. Dealer installed it wrong.
4. Timing signal from 3g was used for something?
