Charge to 100% on L2 charger, but GOM shows 84% on startup

Ford has said it may take up to 22 days after a module has been replaced for these issues to settle down. Search for SSM 52039. I hope this is your issue.

Thanks for this! I'll give it another week and see if this is the case! I went ahead and charged to 100% on Friday instead of my usual 90% and it didn't seem to have the issue. So hopefully it's just as you said.

Definitely check your coolant level after this repair. I noticed my battery temp slightly elevated after a short fast charger session. The truck never had an issue with fast charging. I checked the coolant reservoir and it was bone dry. I added up to max. After a couple of days, I had to add some more. I think I caught it early, but this could have been detrimental.

With such a quick turn around they may have not vacuumed all of of the air out of the cooling system, so you might want to keep a close eye on the coolant reservoir. You can buy a gallon of the proper coolant and keep the reservoir at the middle in the reservoir if you see the level falling.

What brand/type of coolant are we supposed to use? I will need to check mine, wasn't aware this could be an issue after the module replacement. I did notice that the first time I charged after getting it back I was hearing some gurgling sounds from the battery area as coolant was circulating, and am worried there is air in there or not enough coolant. Will check when I get back to the truck.

I do not get why there are four variants for the Cooling System Capacities. Must be for those who have the Max Tow optioni?

On my first long trip (2,000+ miles) since replacing the bad module. The battery pack seems to be charging better than it ever did before. I have a feeling that the module had been going bad for a very long time.

Slightly off topic: does anyone know a hack to setup home charging at 65%? I am not sure why Ford thought it is a good idea to do it right for one time charging but not here.

Nope, we noticed early on that the settings granularity was inconsistent below x value

Well I started experiencing the same today, coincidentally after the Window Update. Charge to 90%, app shows 90% but the instrument cluster shows 89% smh

Close enough for government work, LOL.

I just got 25.12.0 this morning, I'll pay attention to this evenings recharge to 90% and see if it drops to 89% after unplugging.

Just came back from a trip over the weekend and everything was great, holding charges at higher kWh longer and getting on the road sooner.

Edit: this morning back to normal. Odd, but happy. Will continue to monitor.
