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.
