CSP-23B57 for High Voltage Battery Notice

[LUXMAN]

It affects Lightnings built before that date range as well...because everybody needs the BECM update no matter when your build date was. The trucks built during the build date window will need their packs dropped, but everybody gets the software update. At least that's the way I read it.

OK. I am confused here. Where does it say you need to have the pack dropped (modules replaced) if in the build window?

They didn't replace your whole battery, so you have other cells that could go bad. It likely depends on when you had that done. Did they have this SW then or update it since then? I'd think you still want it.

I'm just not understanding how Ford couldn't turn this into an OTA within days and get it out to the vast majority.

Well @GDN some of us don't get OTAs. Some of us are on the Naughty List, as you know

I am wondering the numbers change with a different Soc. I will check tomorrow after charging to 90%.

Good to see someone else's numbers! I'm curious about that as well, it seems your module variation is ever so slightly higher than mine, but I'm pretty sure it's still well within the margin for error. Do you only ever charge to 90%? And do you recharge everyday or wait until a lower SOC to recharge?

@MickeyAO we could really use your expertise here! I'm also curious if you know whether the Lightning pack top balances or bottom balances and what if any effect never charging to 100% has as we also know that is detrimental to cell health.

I encourage everyone who experiences reduced power to file a NHTSA complaint. It's certainly looking like the Lightning has a design defect with the batteries. These module failures have been happening for a year now. Our 80k and up trucks are going to be worthless if Ford doesn't take care of us. There are nine battery modules in the ER and no guarantee that all nine won't have a problem at some point.

I predict a huge lawsuit between Ford and SKS not to mention the inevitable class action.

Some day we there will have to be an operation on your truck to have its brain tweaked just a bit.

4% of 36,611 trucks = 1,464 total needing new modules, I wonder how many have already been addressed?

Where did you see 4%?

 

[LUXMAN]

@ctuan13
Here are the readings from our 2 different trucks.
Both Standard Range batteries at 2 different SOC.

Would be interesting to know what is Module Variation that triggers the Reduced Power and what requires a PULL OVER NOW - YOU ARE GOING TO DIE message.

I need to look at Car Scanner again and see if there is a MaxModV. Obviously there is a Min, Avg and Variation so not needed but funny how the reading on the truck on the right shows a variation of 0.01 but the Min and Avg are the same

Sorry, I have no information about this recall other than I just checked Oasis and my truck is included.
I also do not have ANY information about the BMS as I have not deep dived into the data we collected on our test vehicle.

I will tell you about the danger of mismatched voltages...let's say you have a string that is sitting 0.5 V above the others. As you charge up to 100% (4.2 V using CC/CV) that string is now being overcharged and is more likely to go into thermal runaway. A cell 0.5V below others can be damaged if going down to 0% SOC, but the dramatic effects are not near as great.

When we are charging a module up to 100% SOC without an active BMS for a safety test (all the things manufacturers tell you not to do ), I require an engineer to sit there and constantly monitor all the string voltages.

Now for the big takeaway...am I worried about my pack being included? NOT AT ALL. Do you remember what I've always said to charge to unless you REALLY need to go above it?

 

[GDN]

Where did you see 4%?

It's way down on the next to the last page of the document. The total document is 7 or 8 pages.

"Less than 4% of the affected vehicle population is expected to require one or more high voltage battery modules needing to be replaced."

 

[TaxmanHog]

Post 3 has the document.

 

[LUXMAN]

Don't have it either. I've got the same 7 icons on iOS. I have the CSP listed in my account through a web browser however. Closed and restarted the app, still nothing. So it isn't just Android, as usual, its Ford.

Mine just popped up with the CSP listed. It's currently early Saturday morning and may have been there sometime yesterday but the CSP was completed on Thursday early afternoon. So maybe the notice will leave the app by Tuesday if they update the system

There is a battery health "tool" routine in FDRS that evaluates your battery pack. The reason I said that those in the listed build window would have to have their packs dropped is the inference that Ford thinks vehicles built during that specific timeframe time may have some issue with one or more cells due to some analysis they've done on failure rates they've seen during certain build dates. Trucks that are outside of those build windows will likely only get the powertrain modules updated (the BECM is in that group, but it is scripted to update with all other powertrain modules at the same time) and that's it.

I haven't seen the instructions to the tech yet so I don't know for sure, but if I had to guess I'd say the tech will be instructed to run the battery health analysis, and if it passes then just program the powertrain updates and job's done. If the health analysis turns up one or more bad cells then the pack has to come down for replacement of the bad cell(s), and then the powertrain modules will get updated after that's finished.

 

[VictorM]

I wonder if the CSP tile is dynamic?
For those of you NOT seeinging, are you still listed as affected when you search via the VIN check?

I got my notice. My guess is the truck will be shipped to dealer, dealer does all updates, I take delivery. Let the chips fall where they may.

this is at 90% soc on display, parked overnight.
If the battery is 143.4kwh, I am assuming that it is at 122kwh which would be equivalent to 93% SoC for a 131kwh capacity. Since I do not know how to account for the variance in these numbers, I will conclude that the numbers below cannot be used to confirm anything, so I will not review them. Once the the module fails, I’ll get it replaced and move on with life

 

[Maquis]

I have asked my dealer on a couple different occasions and they keep pushing back and say I need the letter saying parts are available. (Frustrating!!)

I don’t think you’ll get a letter stating parts are available.
Ford used to do this years ago - I got one for the brake light switch recall on my 2000 F150, but no longer. The Mach-E/Lightning headlight switch is a good example.
