2023 Lightning Pro
My 23 Pro has been in the shop for 12 days now after a second tow when the 12v died and truck gave me the stop now warning. The tech knows there is a 12v drain and high voltage failure, and has been trying to replicate the failure but can't yet trace where the fault originates so he's contacted the Ford technical escalation team. Meanwhile the truck is getting a daily workout, accruing a lot of miles and charging to 100%. As I said in a recent post, and while I'm not a software or hardware engineer, this could well be a software problem. Anyone remember scratching their head over an old Fortran If Then Else End error? 🤔

This is painful to read, and I can only imagine how frustrating it was to watch your Flash get winched onto a flatbed. That is absolutely not the experience you signed up for, especially after getting another Lightning.

The "orange ring" combined with a total 12V failure is something we need to look at closely.

I want to get this in front of our team to investigate and ensure the dealer has the technical support they need to diagnose why that module failed.

Please send me a DM with your VIN and the name of the dealer you are working with. I'll escalate this on my end and keep an eye on the case.
Once again, Thank You Brian, for scanning these threads. I haven't needed your help YET, but I hope your here when I do.

Well, I don't drive my Lightning a lot, (occasionally, once a month I do a 45mi round trip). I charge to 90%, and let it get to 60 - 70% before charging on a level 2 Ford Stock Charger. I have notice after a while of charge cycles, the GOM slowly drops a mile or two at a charge. Once every couple of months I charge to 100% and it raises the GOM ceiling, then after doing 90%ers, it starts to drop again. I think this is SOP

Curious, what is the consensus on how often you should charge to 100%? I think I've only done this twice thus far.
If you have an OBD reader, just keep an eye on the voltage variation metrics. If you see variation start to creep up then it's time to top balance (charge to 100% overnight). That's how I'm treating mine anyways. I charge to 100% about once a quarter for road trips and that seems to be enough for my battery to stay balanced.

Get yourself a cheap 12-volt monitor that you plug into your cigarette lighter. It's around 10 bucks and that way you can see if your battery is starting to get weak, so you can throw it on a charger before you have these problems. And when I mean charger, I don't mean the high voltage charger cuz you got to be driving for that to work. If you're only driving short periods, you're probably going to need to invest in a small trickle charger or a 12-volt charger.

Sorry to hear your Pro has been stuck in the shop for nearly two weeks.

Your dealer is taking the right steps by escalating to our technical team, I double-checked from my side to ensure that the team has been in contact with them and I can confirm that they have been working to assist your dealer with the diagnosis and repair of your Lightning.

Don't have to be driving, just turned on sitting in your driveway will charge the lvb.
