2017 FFE Battery degradation

If a cell is misbehaving, don't be surprised if it abruptly gets worse.

Spirilis: You mention using an OBD2 scanner that is showing you real-time data.
As a new owner of a 2017 FFE (42k miles on odometer) I would love to know what OBD setup might work on this car.
Can you advise?

Check out FORScan and the OBDLink EX cable. Also FORScan Lite for smartphones and one of their recommended Bluetooth OBD dongles.

Highly recommend having these tools in your arsenal.

Yep- it's not "sudden" but we just started getting a wrench "See Manual" with code P0BBE, "Hybrid/EV Battery Pack Voltage Variation"

The voltage variation sits around 0.31V at rest after driving a few miles. Funny since I wrote back on Sept 22 it was at 0.17V

I will call the dealer soon.

And it's at the dealer... we'll see what comes of it. I'd probably take the buyout if they offer one. Our needs have changed and there is something going on with the frontend still (seems steering related), kinda sick of dealing with it.

Update-

Dealer's playing dumb, sent me an invoice for $24,283.10 for the diagnostics plus battery replacement. The service advisor claimed he looked up & down for warranty info before sending this to me.

He also had the vehicle description wrong, listing my C-Max Energi instead of the Focus. After getting that right, I opened a case with Ford, who suggested the service advisor should talk to his local warranty rep from Ford.


edit: It looks like, in fact, I might be in the wrong; as it has 102K miles, and it's a ZEV not a PZEV, its warranty might have ended at 100K miles. It has 102855 right now. I guess I'll have to see what the dealer warranty rep has to say about it. I was under the impression BEVs were covered for 10yr/150K in CARB states, but that's only for PZEV, not ZEV (i.e. BEVs).

Ouch, that hurts. I'm sorry to hear that your battery is out of warranty. Going to make it tough to get anything out of Ford. Good luck.

Yeah they haven't got back to me but it needs something front-end on top of this, I am not sure where to go from here. Probably ask them to diagnose the steering clunk (related to all this front-end stuff I've been looking at) and if it's not too much, fix that & drive it 'til the battery stops working.

Very sorry to hear of your warranty travails. If there isn't a business that services/rebuilds OEM batteries, there ought to be.

But here's my question following on this topic: does anyone know what is Ford's official definition of acceptable "degradation over time" as this phrase is used in their battery warranty language to limit their liability?

I have a 2017 Focus electric whose battery has lost somewhere around 20% of its capacity (give or take), so somewhere around 3% a year. It's well under the 100k mile limit. Does anyone have any experience with such borderline issues?

So it turns out there is!

$15K for the replacement battery, plus a core charge - but they will only warranty the replacement completely (**) if you use one of "their shops" to do it, where I assume the core is dealt with in the same visit.

My car just isn't worth $15K plus whatever install fees (fwiw, Ford's official invoice to me listed $1058 for their install cost) to have it swapped.

** - I thought the warranty was void entirely if you self-install, but it looks like the warranty still applies just minus installation faults etc. I would never dream of self-installing this anyhow and they won't warranty the battery if it sits around after delivery more than 30 days.
