Unable to Set Charge Limit

[Tralfaz]

Hello,

I had the issue with my 2024 Flash built in December 2023. Dealer couldn’t figure it out either. Found a similar thread listing CSP 24B48 August 22, 2024 with build dates December 15, 2023 - April 4, 2024 which reported the problem and the SW fix. I took a hard copy of the CSP I found with a google search and requested the described updates at the dealer. They updated the PCM. It allowed me to set charge location and limits. Covered under warranty.
The need for this CSP did not show up in my FordPass app.

I would assume the previous owner may not have used the function and lived with it. I hope this solves your issue. My Flash is the best vehicle I have ever owned.

Now I recall this issue with certain model year Lightnings!
I hope the @Sbpatel82 has success with the delete & rebuild of the charging scheme after the 12v reset, but if the problem persists this CSP might be the true solution.

I just wanted to give everyone an update and see if anyone else is having the same issue as well.

I let the target charge problem persist and was going to address it the next time I took the car to the dealership. I came up on my 10K mile service, aka tire rotation, and I called the original dealer I took the truck to on my last visit. They again suggested that the resolution was simply for me to wait for an OTA update. I was not satisfied with their answer. They were combative and not sympathetic to the issue, the service desk basically told me that the truck is still driveable and so it isn't a big deal.

I ended up talking to and taking the vehicle to a different dealership, they performed two recalls, and several warranty issues along with the 10k service. They replaced the 12v battery as the truck would persistently go into battery saver mode. They also replaced a headrest and a weather strip.

As far as the target charge was concerned they tried several things, including performing a master reset. They replaced the TCU (telematics control unit) as well. That also didn't resolve the issue. I suggested the CSP @TaxmanHog posted about and was told that the campaign had ended and the current module update was beyond what the CSP was calling for anyways. The dealership had the truck for over 2 weeks.

They escalated it to Ford engineers and in the meantime they gave me the truck back. The dealership recently asked for the truck back and I dropped it off last Thursday. I was told they were trying to perform a rollback on the last update since the target charge was working prior to the update. They were supposed to have the vehicle for one day, they called back and asked to keep it through Monday. It is now Wednesday and I haven't heard anything back yet. I know another master reset was done to it as I received a notification email. The last communication that I had with the dealership was that they are working with Ford engineers and that the engineers had never seen this issue before so they are trying to break it down and they are trying a number of different things to fix it. They had used software to try and roll back the update, but they couldn't get it to install or umm uninstall I guess, lol.

I have to say that this dealership is actually willing to try and deal with the issue whereas the original dealership had just thrown in the towel and simply stated to wait for an OTA. I had been waiting since Nov 2025 for the OTA and this is a semi necessary feature of an EV. Ford themselves doesn't recommend charging the battery over 90% on a daily basis and without being able to set a target charge I have no control over that other than to be constantly monitoring it and stopping it manually whenever I thought it was close to 80% or 90%

I hope to have a resolution soon as this is getting to be a burden. There is no loaner vehicle and luckily I have an extra vehicle at the moment, but there is no ETA and I am not sure how long I will have the extra car.

Does anybody have any other suggestions or have others experienced this issue?
