Hello,
My 2017 Lincoln MKC has had FOUR batteries installed due to cells going bad. The dealer can't find anything that is causing this. Any one out there with a similar problem? Or a fix I can pass on to the dealer. This vehicle was new last August (2017) and currently has 7,000 miles on it.


ANY HELP WILL BE VERY MUCH APPRECIATED.

Thank You:(

I presume you purchased your MKC in August 2016. Your problem sounds like excessive battery drain, since you do not have many miles in 10 months, so your car sits a lot. The dealer should have measured the drain by connecting an ammeter between the ground strap and the battery ground terminal (after separation of course). If all the anciliary equipment is turned off there will be a draw of 500 to 800 milleamps depending on equipment. After an hour or so the systems start to shut down and go to sleep thus reducing the draw. In all probability the draw on your battery is higher and the battery is discharging quickly. This is a common problem leading to sulfated battery plates that will not charge properly and the problem gets worse until battery failure.

If the above is your case then the fix is to pull fuses until the excess draw is found and the circuit repaired. Your dealer may already have tried this with no success however.

Good luck.

Check this out. They fixed his issue after couple of visits. Maybe it is across multiple MKCs?

I have same issue on 2018. 3 separate times. Car parked in garage, locked, 3 weeks each time. First 2 times able to re-charge battery thru jump after 30+ minutes. This 3rd time, nothing will turn on after 2 hours of jump connected. Calling dealer.

I have the same problem and Lincoln refuses to acknowledge or stand behind their product. My 2017 MKC has been in the shop six times. Each time they think they have fixed it. They have replaced the instrument cluster, the battery, the hatch door patch, etc. This last trip to the shop it even died right in the shop after they charged it overnight. It has been in the shop 6 days so far this trip trying to diagnose it. Now they say it is a failed gateway module. Maybe it is, but each time I have brought it in, they say they found something. I requested Lincoln Corporate to make a good faith buy back - they refused. It doesn't qualify under my state's lemon law. So much for the "good faith" of Lincoln. Well after the owner of six Lincolns, this will be my last. Too bad, I really like the car, but it is 100% unreliable since you never know when it will be dead. Perhaps I should park it in the lot next door with a big lemon on it.

My battery has to be replaced an average of every 6 months. 2016 MKC Reserve.

I believe my 2017 mkc has this same issue. Is yours still fixed? How long and how many miles have you put on it since the fix? Lastly, where exactly can the main computer module be found? Was t clear where it is in your video (found at 11:40 in video)

That is not my video. It belongs to a Youtuber. His issue was resolved atleast for the time being.

Have the same issue on my 2017 MKC. Battery randomly goes dead while sitting in the garage.

Have been to the dealer four times. Replaced battery, replaced ACM, updated liftgate module, updated something else. Running out of things to replace and patience.

Hello,
I had a similar situation with my 2016 Lincoln MKC. In my case the problem turned out to be a lose ground wire (next to the battery bolted to the car chassis). Apparently when the Auto Zone tech changed the battery a few months ago, he didn't tighten the cable well. Accidently i happened to touch the cable and it as very hot, moreover when I wiggled the cable a bit, it sparked. Anyways, I tightened the cable, and the warning lights went away...Good luck with your issue!!

Ericdkollar, it would be nice if you explained a little bit more of what you found. You say "it's the instrument cluster" and show that the car, in its current gutted state, has what appears to be a negligible current draw ... but the car is gutted. What was your current draw when the car was assembled? How did you narrow down the instrument cluster. Are you saying that simply disconnecting the instrument cluster would have gotten to your 0.01 (mA? A?) draw?

I suppose the good news is that you're practically half way towards making a race car out of the MKC! ;-)

I was at 1.12 amp draw for the entire duration of this teardown. Even after everything I unplugged. Once I unplugged the instrument cluster I went to 0.01 amp draw. I ordered a new instrument cluster and stayed at a 0.01 amp draw after I put everything back together. I have a lot of time invested into this issue and I hope ford finds a fix because my customer will not be happy when there 1000 dollar cluster causes a draw again 2 years down the road

Also when I pulled the cluster out it was piping hottest the touch. So advice to anyone else searching the same issue would be to temp it before you pull it out

Thanks. Both your replies help a lot. Just knowing that the faulty cluster is abnormally hot should help others avoid the complete teardown you went through.
