108 days later:
One module was replaced under the recall program. I also had a wiring harness replaced because it had a hole in it (? presumably they mean the casing), a bus replaced, and debris was cleaned out of the tub. The cause of this was prior work done by a different shop under the...
I'm not sure how @AntJohn73 has fared, but for me the saga continues.
I got a call end of day yesterday that my truck was ready. A battery module was replaced, the BECM module was replaced, and the truck successfully charged to 100%. Great! (@GoodSam I clarified the replaced module was not in...
I need to clarify with the dealer whether the bad module is the new one. Looking at my charge history, I suspected is was bad out of the box because it 'falsely' charged to 100% the first time the dealer charged it.
Try charging a bit higher, say 90%, but pay attention as it charges to see if it jumps up to 100% at some point around 85%, or if it just happens at any set charge level.
Another update: in the process of balancing they found that one of the replacement modules was bad.
So it seems that in fact even a bad module might not throw a yellow wrench! It still seems like a good thing that the truck remains driveable, but you'd think there should at least be an...
My dealer has confirmed a full balancing is needed. The service rep told me the original instructions from Ford were to balance the new module to match the battery. Now Ford tells them a more involved balancing is needed where each module, new and old, will be balanced and the voltage set to...
I have one interesting observation from yesterday. I plugged into an 80A tesla wall charger at work. My truck charged normally to 59% displayed, then it dropped to ~1.1kwh and appeared to be working on balancing for the next four hours before I hade to unplug to go home. SOC variation did drop...
@AntJohn73 I also have a code "P0B24(21) Hybrid battery A - voltage instable". I'm curious if you have it as well.
@Grumpy2 Yes, the same recall repair. I was planning to write a follow up over there when its finally done.
