Class Action Lawsuit - Home Integration System

[Jim Lewis]

So whats the latest consensus on if people's systems are working now or still out of service?

See related previous posts in the thread on 10.3.0 Powertrain update. According to @tearitupsports, there was also an FCSP firmware update several months ago that required truck/FCSP BT repairing, but things seem to be working better now. 2x in a row, I got manual backup power transfer working with no fiddling.

You and me both. I haven't been able to get anyone to direct me to the law firm. I think it may just be blowing smoke. I'm currently trying to find my own attorney who will take the case.

Consumer attorney is doing mine. Just sent more documents and owe them more Monday

I am definitely interested in a class action. My Job 1 22 XLT ER has never worked properly with the $10k HIS after many hours and many replaced components.

 

[Pitbull2o08]

I had another stint in the dealership again, so I sent that document into the attorney. She said ford is working with her but not sure what that means. Will update if I can. If I get an NDA then obviously you won’t see me again.

 

[RDeFran]

Before you sign an NDA could you give us a lawyer referral so we can open our own suits?

Yeah I will before I sign, IF this gets a good resolution. Because nothing has happened yet. I would encourage you though to find a consumer law in YOUR STATE, because my state isn’t necessarily your state.

I need to make a new thread but I was able to get mine working after 70 plus emails with Ford engineering.

I would say that if your truck hasn't gotten updates you should pursue with Ford BEV hotline getting an appointment at a dealer to fix whatever is preventing that. In my case the gateway module was stuck in a state where updates were off no matter the setting shown on screen.

Confirm the inverter is up to date. There were some fixes in the newest version. I think it was version x.x.36

But most importantly and what fixed it for me was a hardware install issue. At some point they changed the installation and no longer connect the common/ground on the rs485 port. Old installs have orange landed there but this screws the transfer up and causes it to hang and eventually fail. Sunrun tech lifted this orange and it transferred properly immediately after for me.

If your having what looks like good transfer but then no power followed by failure after 1 to 2 minutes check if you have this orange communication line landed, it should not be.
I'll add in a before / wrong picture for reference.

I'll remove the cover tonight. Did they just push the orange pin connector back to isolate it or just cut the wire?

It's communications, they lifted the pin from the green connector. They left as much as they could but cut the exposed copper so it doesn't short with anything. I think they wrapped it up with the other unused conductors in the event it ever needed to be used in the future.

IIRC, yours wouldn't transfer at all before the wiring fix you got. Mine can be started manually through the truck SYNC IBP screen or through the charging port UNLOCK button trick, but backup power transfer won't start automatically. So, I wonder if there are still other software/firmware/hardware problems to be solved beyond the rs485 common/ground wire problem that you had. Is Ford BEV support smart enough to triage this or do you think now it's a better bet to get Sunrun to come out and examine one's wiring in light of lessons learned since the initial install (which was over two years ago for me); I have a 2023 Lightning ER.

Also, can you disclose an e-mail contact (maybe via PM). I have the texting support option but I prefer e-mail as I can use any device for that.

Jim,
After the 10.3 software update, automatic backup seems to be working for me (except if the truck has been off for a long time). If I have already used the door or have the truck on, it seems to start each time without having to re-plug the cable several times. Prior to 10.3 I used to have to unplug and replug the cable almost every time to start the power transfer.

Thanks for the advice, Russell. I got 10.3 on 6/14/25, but apparently, it hasn't had the same effect for me. I do have the inverter firmware ending in .36. What's also strange is that previously there was a period, from about 1/24 through early 4/24, where automatic backup would work and could be revived, if necessary, by a cold reboot of my system. Then things went south, and except for a brief period of Ford tests in October 2024, I don't think my system has worked automatically since then. So, given that my system could work automatically at some point, I don't think I have any hardware/wiring problems but am rather stuck in software/firmware limbo.

My system is functional (though I feel like another test is in order as it's probably a month+ since they fixed it) but automatically transferring 100% of the time isn't quite there yet. I think the issue is the FCSP getting hung up with the Bluetooth connection. The Sunrun guys said the truck goes to sleep after a short time, like 14 minutes, so that could be it too. It's probably a bit of both, sometimes the truck goes to sleep, sometimes the charger needs a reboot. Unfortunately there's no easy way to reboot the charger without full system shutdown. Or taking it apart and pulling the battery connection.

One thing I did thru the update process was repairing the charger for backup power. If your FCSP is still listed as Ford 3000 in the truck you should erase it and re-pair it.

I'll have to do a no prep test and see if after a month plus no reboots it can auto transfer, guessing it won't but then I'll see what I can do before full reboot to get it going. Will report back.

Ford engineering seems like they are working on things it's just the BEV phone support has no clue what the engineering group is doing behind the scenes. I asked that we receive recall like notifications for any critical changes such as the wire issue I had, and to get us HIS owners on a mailing list for future updates and bug fixes but, I don't expect much to come from that.

If either of my guesses is right both could be solved with software updates.
-keep the truck alive while on the FCSP if HIS is configured, even if not charging, prevent sleep and charge the 12v as needed.
-reboot the FCSP 10 minutes after unplug event if idle

If you get the "M Professional" app, available in the App Store or Google Play, you can shut down the Dark Start battery that powers the inverter during an outage before backup transfer kicks in. Although the M Professional app is a third-party app, it's what Sunrun uses to set up the HIS system (I learned about it from the Sunrun techs who set my HIS system up; it's mentioned with instruction on the Sunrun field website:

See Additional Guides on field website page: Field Website - Additional Guides​

​

Instruction for Inverter Setup using M Professional: Troubleshooting_ Issues Commissioning the BDi Inverter.pptx - Google Slides​

​

When you first launch M Professional, it will say something like "No Device Found." But then if you're close to the inverter, if you hit the magnifying glass Search button, it should come up with E4_BDI (or whatever the power of your solar inverter is). Tap on that, and it will ask you for a password. The password is the 4-digit numeric code on your inverter nameplate.​

​

Once in the app, if you go to Menu, Additional Features, DS Battery, you should have the Shutdown option. If successfully shutdown, the green LED light on the FCSP will go out when the FCSP is only being powered by the Dark Start battery.​

​

On the main page of the app, if you scroll all the way to the bottom, you should see a Power Flow button. Tap on that and you'll see an animated diagram of how power is flowing in your system. Tap on Details and it will give you amounts from each source, the grid, solar, or your vehicle, etc.​

Right.
But if you do that during a grid outage the inverter is off and you're done until the grid comes back up. You'd have to open the inverter and try to repower it from the dark start battery and I don't know if that is possible.
You can reboot the FCSP by pulling the ds battery feed though without shutting off the inverter. So during a grid outage this may be the move since it won't mean game over til grid is restored.
