I had basically the same thing happen on October 23rd. Car went fully haywire (started popping insane error messages in rapid fire) and died on my wife. Had to jump it to get it home. Then it died again. Took me 8 days to get an appointment with the dealership - November 1st. Car was completely dead, so they had to send a flatbed out to tow it. It wouldn't stay running without the cables attached, and the driver literally tried leaving my car sitting in an alley. Almost had to fight him to get it on the flatbed.

Now it's been at the dealership over 2 weeks, and there's no clear end in sight. Nobody seems to know what they're talking about. Ford is kind enough to reimburse a rental car up to $35/day for 10 of these days, even though I haven't had a functional vehicle for almost 4 weeks, and you can barely rent a scooter for $35/day. So as of now, I have a $1000/month paperweight taking up space in the dealer service dept. I'll post if I ever get a straight answer, or at least the car back.

Glad you got an appointment. All the dealerships in my area are quoting the middle to end of December before they can even look at it. I have received an email from FORD from a customer relationship rep on the BEV team. Told him the issue and haven't heard back since Friday. My car seems to run fine just don't know if it's going to start. I'm keeping a jump pack with me and leaving my window down. Sucks I have to do that with a $65K car that's only a year old this month. My problem is nobody seems to care at the dealerships or corporate Ford.

This might’ve have been answered but I haven’t read every single comment: does the LVB trickle charged whilst the car is in use - Similar to how it’s done on ICE vehicles - or is it only topped off while the HVB is plugged in and charging?

Yes, there's basically 3 conditions that it will charge the LVB. It charges while being driven, while being charged or during a top off triggered by the vehicle when voltage is low while unplugged/stationary as long as the SOC is above 12%

Excellent. Thank you.

I woke up to a dead 12v, jumped it, drove about 40 miles to work, so hopefully it’ll be good again. I’m a little nervous though. I tried getting the battery tested at autozone but their tester kept giving errors. I’m not sure if it warrants trying to get into Ford or just watchful waiting.

I would recommend getting it to the dealership. The car shouldn't let the battery get low. Did you get a battery drain alert in Fordpass?

Anytime the battery is pulled under 10.5 volts it's life is pretty much cut in half. I'd monitor the voltage closely for a few days. You can also leave 'the car 'running'. Just get out and lock the car with it still running. It'll shut off after 30 min. If the AC/heat isn't running you'll spend less than 1kw or so. That 30 min will bump the battery about 15% soc. It doesn't slam charge the battery like the FFE does. Sadly it's about 1% or so every 5 min.

This weekend mine sat outside in near freezing for the first time I've owned it. I was a little worried about the LVB because my phone and fob were triggering the lights on the car constantly. I moved my fob to the other end of the cabin and closed the FP app. It looked like it stopped triggering them but I have no idea. When I went to open the hatch the normal "ding ding ding" was very quiet. I thought, oh brother. It fired up and drove 200 miles back home fine.

Nope. The last notification I got was one last night saying it finished charging. I didn’t realize it was dead dead until this morning.
I recently had the dealer replace the HVBJB. I wonder if that has anything to do with it…

Side question, now that I’m thinking about it. What does “drive mode unavailable” mean? It happened a bunch before the HVBJB failed and now it’s happening again.

Ok then yeah, I would get it to a dealership. It sounds like you have something going on with the charger for the LVB. It should maintain the LVB, which it sounds like it might not be doing. If it was a bad battery, I would think it would still attempt to charge it, which it's not.

This issue shouldn't have anything to do with the HVBJB replacement unless they screwed something up in the process.

Drive mode unavailable is a different software bug and unrelated.

My son's Mazda3 had the battery completely drained a couple of times due to an overactive dash cam. The newish battery then died after 6 months.

Lead acid batteries usually lose a cell each time it's dropped under 10.5 volts (which includes cranking. So that attempted start on a ICE can cost you the rest of the battery). These AGM's seem to run at higher voltages so it's possible 10.5 could be closer to 11. Not sure what the resting voltage is for these at say 70% SOC. I see mine usually around 60% when it's sat for a day or two.

I guess I’ll give Ford a call. Fun Times…

if your 12v battery EVER dropped below 12.0, something is wrong... and the 12v battery itself will have a shortened lifespan even after the root cause is found and corrected.

if your MME is within 'bluetooth range' of your phone during the day or night, your MME may not be 'sleeping well' since it will ping and wake up for 10 minutes at a time, which hits the little LVB pretty hard as the background computer stuff pulls close to 200watts when it is waking up.

If you park within 100' of where your phone is.... I'd suggest turning off either Bluetooth, or force-stop Fordpass, to let your Pony sleep.

Does that apply when not using PAAK? I never set that up.

well, if FordPass is not running, you are ok, unless you store your fob somewhere close to the car?

I would however suggest setting up PAAK... even if you don't use PAAK, you may want to have the 'backup code' set up in case you lose your Fob.
