Only the connector port is at the front exterior, while the actual BMS modules is inside

But potentially the multiple openings there, sealed by gaskets, provide an entry point for corrosive salty liquid to get into the front of the HVB battery pack "casket" and act on BMS components inside. @Nomoregas has implied that salt and water corrosion is the problem:

as I was thinking if water and salt could destroy this in just 3.5 years

But he hasn't said where it might be coming from: winter road salting, driving on the beach, boat launching, or plowing through swampy salt marshes. The Lightning should be designed to withstand road salt. A defect there is a warranty defect, IMHO, of material, design, or manufacturing, whereas I don't think off-roading that deliberately exposes the vehicle to salt could be considered a warranty issue by any stretch of the imagination (although some might consider beach boat launching a normal use for a truck).

I can say we had a brutal winter in Toronto Canada and it snowed 4-5 times a week so there was salt dumped on the roads constantly which will turn to a liquid mixture at the right temps. I have to assume the BMS at 1100 and 950 labour is not that little component off the 12 volt or the service manager has used the wrong terms but he said the words battery management system but he is new there at 1 month so who knows, when I get the bill I can see the exact wording.

I was hoping to be able to seal that up better than ford did if possible.

I wouldn't do that, as it would mess with the vehicle's design and give Ford an excuse to void any future Ford warranty claims. Ask Ford and your dealer for a repair that can stand up to Canadian winters for the service life of the vehicle.

FWIW, here's an MS Copilot analysis of why it should be considered a Ford manufacturing/design issue covered under the 8-year/100,000-mile EV drivetrain warranty:
https://copilot.microsoft.com/shares/eABtvDPXx9W6cFXsFwuJu

And here's why, according to the same AI, failure of any connector gaskets on the front of the HVB battery pack, leading to leakage into the front interior of the pack where the HVB BMS is located, is not equivalent to a Nissan Stanza head gasket failure I had in the 1980s that was not covered under an extended warranty. The head gasket was considered an item subject to normal wear and excluded in the fine print of the warranty, whereas a connector gasket seal is not a wear item - it's expected to last the service lifetime of the vehicle.

Maybe @Ford Motor Company can say something about how Ford Lightnings are designed to stand up to winter road salt in the U.S. and Canada and whether there is a potential EV design/warranty issue here that needs to be addressed, both to save the owner a $2050 repair cost and avoid other Lightning owners in salty winter road environments from experiencing the same as time goes by.

I have 135,000 KM on the truck I think the normal warranty is 60,000 and the battery is 160,000

The 160,000 KM on the battery would be the drivetrain warranty (battery to electric motors), and it seems that if you're "only" at 135K KM, you're still within that warranty period. I haven't read the fine print on the drivetrain warranty, but, for $2050, it's worth looking into, IMHO.

Just to spread the AI wisdom around, the following link below is Gemini's take on the warranty applicability. It mentions that Ford has a specific road salt exclusion warranty clause, but it is generally understood to apply only to cosmetic corrosion of frame surfaces or body panels. It is agreed that the failure of a battery pack seal within 3.5 years might well be considered a defect in material or workmanship. One thought is whether you were routinely plowing through hubcap deep snow that might have had some icy debris that was periodically whacking your undercarriage. That might show up as impact damage on the affected components. Without evidence to support such a failure mode, a warranty claim of a defect in material or workmanship should be favored by default, IMHO.

Ok so my service advisory got it wrong what was replaced on my truck for anyone else that may experience this was the VDM. The plug corroded resulting in the module failing. I asked if he knew where it was but he did not as I was wondering what allowed this to hapen so soon in life of truck.

The other truck that was in shop and they had no idea what was wrong and did over 9000 work before figuring this out also was failed vdm but they had already replaced several other components that did not solve the issue. Now interesting my truck has 128,000km on it and the other with same issue had 110,000km on it so it seems it is a time bomb to me in salty winter climates.

Anyways truck all fixed and MAN was it nice parking the F350 Lariat and driving this truck again!!!

Do you see any part numbers related to that service task on the work order ?

those prices are are far more palatable!

 

[Nomoregas]

not sure I understand what this part is, here is from grok


The part NL3Z-18B008-B is the OEM Ford "Control - Front, Center (BEV)" module.

ford.com
It is specifically for the On Board Scale system (payload/weighing management) on the Ford F-150 Lightning (BEV/Battery Electric Vehicle models).

ford.com +1
Location: Front, center of the vehicle (as listed in Ford's official parts catalog and diagrams for the BEV-specific front-center control section).

ford.com
This is typically mounted in the front-center area of the chassis/suspension controls (related to standard suspension and heavy-duty dual shock absorbers in the onboard scale setup). Exact mounting is shown in Ford service/parts exploded diagrams for the front suspension or onboard scale system—usually on a bracket or frame crossmember in the front-center section (not in the cab, frunk, or battery area).Note: Some third-party sites incorrectly label similar modules as "air suspension control," but this specific NL3Z-18B008-B part is for the onboard scale system (F-150 Lightning does not have factory air suspension). It replaces the earlier NL3Z-18B008-A version.

rivercityfordparts.ca
If you need the exact mounting spot, check Ford's parts website (search the part number for the diagram) or take it to a dealer—they can pull the vehicle-specific exploded view. No public service manual excerpts or replacement videos specifically detail this module's spot, as it's not a high-failure item. Let me know if you have more context (e.g., a photo of the part or symptoms)!

Possibly the control modules has multiple applications based on coding and related devices it is attached to??

Another issue has been discussed regarding the can-bus networks on our trucks, sometimes a seemingly unrelated part failure has downstream impact on systems within the network, ie. creating false negatives
