It may be a co-incidence, but ever since upgrading the 3G modem to a 4G modem, the estimated time for charging has been garbage, and I cannot use Value Charge.
The modem was replaced back in the first week of March 2020. Prior to that, when the car was in Charge Now mode, when it was shut off the time indicated in the dash was a reasonable estimate of when it would really be finished. If it was in Value Charge mode, where I had it only charge between 11 pm and 6 am, the dash would estimate starting at 11 pm and finishing at a reasonable time later. By reasonable, I mean something around 5.5 hours for a full charge, pro-rated to the percentage needed (e.g. if the charge level was at 60%, then the estimate was about 40% of 5.5 hours). The old app would reflect this as well.
When I got the car back after the modem upgrade, in Charge Now mode, it would say that full charge would take 0.1 hours, regardless of how much charge the car had. If it was in Value Charge mode, it would indicate the start time was 11 pm, with a finish time 0.1 hours later, BUT it would start charging immediately as if it were in Charge Now mode. For the first while while charging, the new app would always indicate the car would be finished charging at some fixed point in the past, something like 7:32 pm on the day the modem was changed. It continued to say this for a couple of months.
When I contacted Ford back in the spring, they indicated that the problem would be fixed with a software upgrade coming in the summer. At one point, the charge time did change from 0.1 hours to 0.6 hours, but still did not have any regard for the charge level. The app's estimated finish charging time did change, but continued to be some weird time, sometimes in the past, and sometimes several DAYS in the future.
While stopping to get a fast charge, the Charge Settings screen often warns (in red text) that there is insufficient time to charge before the next Go Time comes up. I would get this when fast charging on a Saturday when the next Go Time was Monday morning at 7:15 am.
I recently had the vehicle into the dealers for a general service and mentioned this issue. They tried doing some sort of system reboot, but the problem remains. It actually reverted back to the 0.1 hour estimate after being at 0.6 hours for the last couple of months.
Has anyone else had this problem, and was there some procedure to clear it?
I should add that my Level 2 charger at home has a delay feature, so I can have it wait until off-peak times to charge the car. Of course, the app sends me a notification that "Vehicle did not start charging at scheduled charge time" every time I do this - more to be annoyed about!
