No one has solid data until @Ford Motor Company publishes the information.

Seems like quite a few failures on these battery modules based on the size of this thread. A lot of 2023 and 2024 models too with low mileage. I've watched the breakdown videos on the batteries and they seem to be made by SK Batteries. Thankfully Ford designed them to be modular as they are being serviced a lot and losing a lot of $$ in the process. Not sure what's going on but these modules should not be failing so frequently @fordmotorcompany.

Our forum population is only a microcosmic of the entire buying public, if you're a statistical scientist, maybe you could draw some inferences.

Yes, the HVB pack has nine modules, which are easily swappable from the pack, the modules themselves are NOT serviceable, they go to destructive reclamation.

According to Ford’sCustomer Service Program (CSP) 23B57 “Less than 4% of the affected vehicle population is expected to require one or more high voltage battery modules needing to be replaced.” At the time this program was announced (September 13, 2023) Ford stated that 36,611 F-150 BEV were affected, and that the program would be in effect until September 13, 2024.

4% of 36,611 = 1,464 vehicles. What the actual number of vehicles that have had battery modules needing replacement are is unknown, although the technician at my dealership told me in January that he had already done 5. If that is at all typical, then the number of vehicles needing module replacement is a whole lot more than 1,464.

Additionally, although Ford said that the program would continue through September 13, 2024, Ford has continued to replace battery modules under the CSP 23B57 after that date. I have not seen any updates from Ford on this CSP and I would certainly like to know if the program will continue at least until the end of the 8 year/100,000 mile warranty of the battery.

One more point, Ford will not sell you an extended warranty for the battery beyond the original 8 year/100,000 mile factory warranty. (I asked and was told no).
