New recall: water intrusion into BCM and connectors (25C43/25V546)

[Joe_Stang]

I’ve been on here ranting away about how I am not able to pick up my brand new 2025 Mustang GT (financed btw) due to a diode recall and maybe being able to have the issue addressed in Q4 of this year.

Well it got worse, since yesterday they issued a recall for the following:

FORD RECALL ID: FORD 25C43 INSPECTION FOR WATER INTRUSION INTO THE BODY CONTROL MODULE BCM AND CONNECTORS

With that remedy anticipated for Q1 of 2026 lmaooo like you can’t make this up. Now let’s say I decide to allow ford to get me into a similar vehicle well it gets worse

Oh did I mention it actually gets worse?? Well Just searching for new cars close to the specs I want…well all of those are part of the new recall lmao. So dealerships are unable to deliver/sell those vehicles. It is Like the ford gods don’t want me to own a mustang.

I even got pictures of my car from the dealership lot too lmao

Beautiful car man! Damn shame about whats happening

Oof. I remember my S197 having an issue with water getting in the electronics and even into the cabin after a while. Too bad they haven’t resolved water issues yet. Until then, my car is going to get wet. It mostly lives outside and gets washed every few weeks.

Yup just got it. Interesting as my previous thread was about a Check Engine Light as soon as I went to the car wash…

Well for right now the key phrase is : "Inspection for water intrusion"

 

[AZ_Ryan]

Don't get the car wet is the most stupid advice ever. How the hell can a car owner prevent the car from not getting wet?

This advice is only possible for people who buy cars and store them in a garage, not for people who bought this car to drive it.

This is a car ladies and gentleman, not a TV.

Cars drive outside on public roads. Cars get parked outside at the grocerie store, work parking place or other places where there are no garages. And there is also something called weather we can't control. And sometimes car owners also wash their car.

How in the hell can somebody say "don't get your car wet"

Pretty sure he was joking.

as someone said above this has been a problem for 20 years

An awful lot of Mustangs are going to be sitting on dealer lots not being able to be sold, both new and used.

So which BCM is it, the one by the battery, the one under glove box or the one in the trunk??
I’ll just seal it or add dielectric grease or something myself if it’s really an issue.
Ford ain’t touching my car.

You could always try spraying the box down with Corrosion X…a very effective water sealant used for RC electronics in sea planes.

 

[ChitownStang]

Exactly, a silcon spray.. which box??

For over 20 years, the box at the passenger footwell was the issue. This video is just one example of it’s location and cause in the S197. It looks like not much has changed in general.

All the s197's it was the one in the kick panel passenger side. The filter is in the engine cowl and drain holes would plug up with crap. Also the plastic cowl has attacment clips fitting into plastic receptors that would leak.
If I was concerned I would pull the kick panel and inspect for water intrusion. I would think if you had water coming in you would already have an issue. I am surprised for the recall. Maybe this being a safety issue or a bigger water leak for the recall.

S197s could have water intrusion through the firewall into ECMs if the owners were dumba$$es and allowed their engine firewall drains (2) to get full of dirt. Another water issue (not owners fault but common to many convertibles) is water getting into rear quarter panel compartments. A fix for most was to use a sharpened piece of dowel to poke two holes through the caulking bead at the bottom of the compartment joint or to open drain holes in some convertibles. As for our 650s I don't see how this random issue would prevent delivery of the vehicles.

Seriously remove this crap. No need for all this shit. Can buss is a joke and my fringing headlights, radio, windows, or whatever don't need to communicate with anything. Simple switch window goes up window goes down if you need remote up/down just put in a basic radio module tuned to the key fob.. My radio doesn't need to know what piston 8 is doing nor do my windows.

Why do you think this will effect sale and delivery?

 

[roket]

here is the information on affected vehicles and the reason

i've managed to avoid a few recalls, but this one got me. however, i can say that even in some pretty intense rain plus a fair few trips through a car wash, i've had no issues with lighting or the BCM. it's very important to remember that just because a recall like this comes out doesn't mean everyone will have it happen, or that it will now suddenly start happening

 

[hoodscoops]

The passenger side water leak fouling the BCM has been around for over 20 years going back to S197 at the least. Many videos of people pulling corroded modules out the car. Also many on the S197 forum had these complaints.

You’d think Ford would have noodled this issue through by now.

Best preventative measure is making sure there is no debris clogging the drains, but it can still happen. Even better is don’t get the car wet.

Its also known on some of their F150 and escapes.. Wtf ford
