Energi High Voltage Battery Degradation

[rhsrds@gmail.com]

Hi All.

 

I have a 2017 C-MAX Energi with 95,000 miles on it.  When I first bought this car (new) it wasn't unusual to travel 20 miles on pure battery with a full charge, and I could expect around 5.5 kWH at fully charged.

 

Now, with 95,000 miles, I average around 12 miles of travel on pure battery with a full charge, and I get about 3.6 kWH at fully charged.

 

My Ford dealer has done a significant amount of testing at the direction of Ford, and the dealer has been told by Ford that my vehicle is still performing within specifications by providing from 0 - 20 miles of travel on battery only.  (seems like a stupid spec to me by saying 0 miles is still within spec.)

 

While I did expect some level of degradation of the high voltage battery over time, it seems that 30% is excessive over 5 years and 95,000 miles.

 

Is anyone else experiencing a similar level of degradation?  My dealer tells me my best recourse is to start with Ford Customer Service.  Not very hopeful about that.

 

Thanks for any feedback.

It’s probably just that winter blend electricity.
