I too am victim of Ford's poor design. My wife was stranded at the grocery store with the dash going crazy, radio, air and locks unresponsive, unpredictable, and uncontrollable. After I arrived at the scene, I went right to the battery, pulled back the protective cover and found 1/2" copper sulfate caked on the positive terminal. The terminal clamp was completely dissolved. Now I've seen corrosion but this was obscene! We've had the car less than 1 year and a battery cable needs replacing! Wow, I though Ford was on top of their game again. Based upon all of these similar circumstances, I guess it's time to switch (again). And I thought SYNC2 and Navigation was the worst it would get..

After 15 minutes of careful cleaning I finally got down to where I could see the terminal. The cable lifts right off since nothing is left of the terminal clamp.

Last weekend I also was stuck with this same problem not quite as bad as the pic from cyberide but bad, The metal that connects everything was corroded and basically gone. had to get towed to a dealership in Denver on a Friday night as I was visiting there. could not be fixed until Monday afternoon.
luckily I had enough connection to run the radio all night as that is where I slept until 9 am when the shop opened. I am out of warranty and the part was 340.00 and labor brought the price to 996.00. hope it never happens again.

I just had the same problem. Discovered more corrosion then I've ever seen on a battery. I've tried to find the plastic/ rubber pieces which keeps the positive clamp tight but no luck. My next step was to buy and replace the entire plastic piece but just saw how ridiculously priced it is. Anyone how another solution because I can't fully tighten the clamp and it has failed to start several times

Thats crazy! I would have had the dealer clean the terminals. Mine will at no extra cost during an il change if I ask.

I had the same problem on June 20, 2017. My husband could not believe the amount of corrosion and while trying to clean it, ended up with piece after piece after piece coming off. Had to have the car towed to the dealership. Received a call from the service department today telling me that the battery shorted out and caused considerable electrical damage and I am looking at about $1300. I was also told that the battery is only covered under the original warranty and my $1000 extended contract does not cover the battery or electrical. This was the first time I ever purchased an extended plan and now I know why they push them on you........they make money on your purchase, and the plan won't cover anything! I have driven a LOT of Fords in my life, but this is definitely my last one. And Ford Motor Customer Service is absolutely useless!!!

Yesterday afternoon I decided to go run a couple of errands. My 2015 Taurus wouldn't start. I opened the hood, pulled the red cover off the battery to discover a ton of corrosion. I didn't expect to see this on a very well maintained two year old car. I was livid. I took it in this morning for a new battery. The positive post on the original battery was loose which explains the leak. It ruined the cable connection. The bottom half was completely corroded away. Seems to me Ford has a huge problem with bad batteries. I purchased an extended warranty on this vehicle and I have yet to use it. I used the original warranty once for a light bulb replacement. I will take it in to the dealership tomorrow morning. Let's see if they replace the cable.

So are people not properly maintaining their terminals? Dont want to sound negative but how much does a can of terminal protectant cost at Auto Zone?...lol. Or the time to just check every once in a while. My dealer will clean mine when asked during an oil change for no extra charge. Might be something folks experiencing this problem should ask their dealer to just keep them clean.

Just went through this also, I assumed the "stealership" was checking these during regular service...at least they told me they were. So this weekend, my wife, like many others, was stranded, fortunately at a relatives house. I guess I'll try to get the connector today, and have the battery evaluated, as it was recently replaced by Ford, with a motorcraft battery. Anyone have any luck getting Ford Cust Svc to chime in on this issue on their behalf? Or any word of a TSB or other action to remediate by Ford?

Welcome, how long ago was the battery replaced? If there is a fault with the battery it should still have a warranty?

Same issue this last weekend. I thought I would clean it off and reinstall the post, and realized the clamp portion was corroded all the way through and would no longer hold contact with the battery. After calling around and being told that I would have to get the part from a dealership (not open on Sunday), I settled for a generic battery terminal post that had a screw stud facing upwards. After removing the metal portion from the plastic housing so I could keep the electrical connectors and fuses where they are supposed to be, I was able to rig the fuse assembly to connect all cables and connectors, then connect to the battery terminal. I do not think this should be a permanent fix, as the plastic housing is supposed to protect the terminal, but then again, it seems to do a crappy job to begin with, so I will order a new part and see how long my rigging lasts and make sure to provide updates.

I removed the cover to my positive battery terminal recently and discovered quite a bit of corrosion. The easiest way to thoroughly remove it all was to disconnect the leads going to the terminal "housing"
and get it out in the open.
After cleaning I noticed that some of the clamp portion of the terminal was corroded away. Also the"wedge design" retention blocks had been fused together making it difficult to re-tighten properly.
Since all of the connections either plug in or are lug terminal attached to this terminal/housing, I called Ford for a replacement. Guess what? you cannot purchase simply a positive battery terminal or the plastic housing it is mounted in. You have to buy the entire positive cable/harness assembly for over $300.
I am livid! I would pay a reasonable price for the terminal and housing, but I refuse to spend that kind of money especially when the cables all disconnect from the assembly and are in good shape.
Anyone else have a similar issue? Any suggestions would be appreciated!
Hi. Last nightly sister called me with a no start issue. Three weeks ago it was the remote start programming went back to default. So I go check it out for her and lift the plastic cover to the positive lead on the battery. Yep you guessed it, so much corrosion you couldn't even see the positive post! So not just being one to have my Sis shell out her hard earned cash for replacement parts on a 2 yr old car she bought new from a dealer and has always taken it to that dealership for service and oil changes I looked into what could be causing the issue. And to my surprise I ran into your post first thing. Exact same issue! What does that tell me? This is NOT random. So I did some research. Eg I went to look at her car and battery specifically. The corrosion is caused by gasses which leak from the battery. So when I disconnected the positive lead it fell apart in my hand. Corrosion had eaten through the lead! So I took it off completely The first thing I noticed was that the plastic case that is supposed to protect the positive lead was broken around where the positive post goes through the bottom. This was NOT manufactured in this manner. The break was obvious. So I'm being logical. What caused the break. Knowing from experience that those cables are tight. So tight that it is hard to remove the cable from the post under normal circumstances. I got to thinking that when the battery was installed at the manufacturer whomever was on the assembly line may have damaged the plastic cover and on doing so ALSO may have damaged the battery. So. . . I inspected the battery. Guess what. The battery IS damaged right next to the positive post. It has an indent. No visible crack to the naked eye but obviously damaged. My train of thought here is this. At build this damage was caused. The line worker could not see the damage to the battery because it was hidden by the protective case. The gases thst were emitted from the battery were trapped in the plastic case, because it is sealed fairly well on top is it not? This caused a buildup of the gas aroubd the positive lead which initiated the corrosion to the exposed copper lead and caused to to eat all the way through. Hense creating the issue you and my sister are experiencing.
This (should)be covered under the manufacturers warranty because it is a manufacturer defect is it not? My sister certainly did not cause this defect, you did not cause the defect, it was done at build. (assuming my theory is correct) now this is not the fault of the manufacturer of the battery. So there should be no passing of the buck on this okay. This, assuming yours is the same issue, check the plastic cover which encases the positive lead, is it visibly damaged? Then check the top of the battery around the positive post. Is there damage? An indent? You'll have to remove the plastic case and clean off the corrosion to see it. Look close. It's not very big. If so, we may have discovered the root cause. In which case, it needs to be reported to Ford. So they can address this appropriately. This (should) be covered by the manufacturer warranty. The solution is. . . Replace the harness to the positive lead AND the battery. If the battery is not replaced you will still have the same issue recurrance. Can you feel me? I do not post this because I do not like Ford, or that I am not informed or experienced. I am an automotive mechanic. And further I am a service tech at a Ford dealership. That's right, this is why my sister called ME first. I've seen this before. Only now closer inspection did I put two and two together. I've seen the exact same break in the plastic case. And the exact same indent in the battery. If you PM me I will send pictures of the damaged case and battery to reference. I'm not saying the issue is exactly the same in every case but the similarity is much to close to be coincidental.

I am addressing this issue with my supervisor who is the service manager at the Ford dealership I work at, when I go to work this morning. I'll update this post once I get more information. I can only hope I don't get terminated for addressing this in a forum. But I have to think Ford is above that. They seem to treat their customers well and fairly. It's about a $500 fix to the consumer if they won't cover it under warranty. That's just an estimate though.

Hi! Well if you read my previous posts pertaining to this issue you may be enlightened. Let me start off by saying I am a service tech at a Ford dealership. No, that does not mean I am on here to defend Ford. I am here to shed a little light, I hope on this issue. Here is the scenario. My sister who owns a 2016 Taurus called me last night with a no start issue. Not the first electrical issue she's had. It started with the remote start programming goinf back to default etc. What I found out was happening was the copper leads on the positive battery connections were corroding away. This is not readily visible because the plastic case that covers the lead Shields it from the casual inspection. I have to defend Ford on this one.
Here is my theory and you may agree on this or agree to disagree.

The cables to the positive post are tight, there are at least three cables and they go to different locations. The positive lead is protected by a plastic case. So at build (speculation ) the person on this line forced the positive lead down on the battery damaging the case AND the battery. The protective case on my sisters vehicle had obvious damage. Which was not readily visible until I removed it and only then did I note visible damage to the battery as well. An indent near the positive post. This was only noticeable because I was searching for damage to see what caused the issue, can you feel me on this? The corrosion was caused by leaking gases from the damaged battery which were trapped inside the plastic case which is supposed to protect the positive lead on the battery. Which caused the corossion to eat through the exposed copper leads and break the connection to the fuse box, starter, etc. (this is my theory) judging by the description of issues on this thread and the physical evidence at my end.

I would suggest that if you have this issue or similar you perform the same inspection I did. Check the plastic case for damage on the bottom. It was obvious on my sisters vehicle, if so you should check the battery anyway to see if it is damaged. I can post pictures of you PM me and you can compare them.

The resolution is going to be to replace that section of the harness AND the battery. If you do not replace the battery this issue will recur. You must mitigate the root cause.

Hope this helps.
