Well, I was hoping to bring a proper resolution, but one does not exist yet. I thought I'd update with what I have so far.

I sent it to my local dealer. They said it had "100 codes." They cleared them, did software updates to various modules, and thought the truck was fixed. It had the exact problem as soon as I got it back and is now back at the dealership. They have spent more than a day working on the truck and are pretty lost. They have reached out to Ford for information and are waiting to hear back, but the thick plottens....

Apparently it has had this issue in the past, with the original owner, as well as the dealer who I bought it from. The original owner (A corporate/company vehicle, I believe) had this issue in California. The dealership there knew the exact truck as soon as my dealership called. They spent 40+ hours trying to diagnose this without resolution. They contacted corporate for help, but were unsuccessful. Apparently the service department just found it had been taken away one day, so never got full resolution. I suspect it was taken to auction at that point, though I don't know exact timelines.

The dealer I bought it from (small time individual) had the same issue in Georgia. It was in, I think, twice. They replaced a module/computer of some sort (just verbal from my dealer so I'm not sure specifically). They also reached out to corporate for help, because it was a difficult problem. They say their tech notes are very vague so they are unsure if it was actually a verified fix or not. I suggest, at this point, it was not.

Of course I got a Carfax report, but these seemed like fairly innocuous software update issues, which aren't exactly red flags with a new model EV.

So at this point I am without a truck, a timeline, no known cause or correction, and no idea whether it's covered under warranty or not.

Sorry to hear. Good luck. Mine threw about a hundred codes when I had similar errors too. Really sounds like a short in one of the dozens of CAN bus pairs or any of the modules on those CAN buses. No doubt it’ll be hard to trace but mine hasn’t had any residual problems since I figured out what was causing it. Hope you get the same result.

That was roughly my assessment (the semi-mechanical nature of initiating on turns and with movement) as well as their tech's thoughts. A short between wires or to ground. Their tech monitored it while driving and saw repeated momentary cut outs of communication systems of some sort. It fits well, but sure could be hard to trace...

Do you know what the fix looked like in your case? I don't know how accessible the wiring is for these trucks, nor how amenable to repair the harnesses are.

My situation was entirely self inflicted. I had loosely tapped the back of the OBD2 port for power to my comma 3x. While driving the pins I had used came lose and either 12v or ground was making contact with the other pins for the OBD2 port.

My symptoms were exactly the same as yours. However mine triggered when I was fiddling around near the OBD2 port. I went to plug in my aftermarket power running boards and it was driving fine, then all of the sudden stop safely now, no power, blind spot fault, traction control, pedal dead, battery 0 miles, odometer had dashes. I pulled the 12v battery connection for 30 seconds and was able to get about another 2-3 minutes of driving before it happened again. This time I fixed it by clearing codes and pulling the 12v battery but the moment I went to unplug my OBD2 scanner it happened a third time. I removed the power wiring I had done for my Comma 3x and haven't had the issue since. Even took it on a 1000 mile road trip over New Years.

Likely not the exact same issue but this will give you an idea on the harness repairability.

Interesting. That is fairly external/accessible and was tied to a known modification so that definitely helps with diagnosing and fixing. I'll cross my fingers for something reasonably accessible.

Aside from a fire extinguisher mounted under the rear seat the truck appeared entirely unmodified, but there is always some chance there was a camera system or something similar added previously.

If all else fails and you decide to give up on it maybe @Martin Rebuilds would take it off your hands. He has been rebuilding these things since they first came out.

Wiring issues are almost always difficult to track down, and there is an awful lot of wiring in these trucks that could easily be damaged.

You might take a look at the modifiers guide for the 2022 and look for any wiring esp connectors to sensors, that might be affected by turning? I'd think the bad connector or wiring damage would be near your front end, so you might lift the Frunk floor off to get a better look - of course there is HIGH VOLTAGE wiring under there so be careful what you fiddle with!

This is a link to it I saw on the forum in another post:

https://web.archive.org/web/2022070...ces/2022_F-150_BEV_Modifiers_Guide_5-3-22.pdf

Detailed wiring diagrams sometimes are on sale on eBay - didn't see one for the Lightning last time I looked - or sometimes on other web sites.

I see someone was looking for a specific one for the connector guide on Justanswer.com and got one:

https://www.justanswer.com/electric...ring-diagram-2022-ford-lightning-bev-xlt.html

A complete service manual can be expensive - this one is $750:

Whether it helps with this situation or not, that is a very nice document to have. Some of it is basic best practice, but some is explicit and informative.

I really hope it doesn't come to that, but it's good to know it might have some value and utility in the worst case scenario.

You would hope the Ford tech have all the needed information to find the issue, but these days they often go through machine diagnostics and error code look up rather than using common sense and looking for a bad connector or wire.

The general Ford folks might not be much help either.

Did you try the BEV team?

When all else fails, contact the BEV team at FORD: BEV Hotline 1-866-631-3788, or 800-392-3673, 571-831-5352

Any cracks or damage to the tail lights? I’ve seen stuff on youtube mention that water intrusion in the tail lights can short and disrupt the canbus and shut trucks down (seem like the dealer would have checked for this though). Maybe look for DIY repairs that would not have made it to the carfax that the PO could have done. Do you know how many miles it had before it started being brought in for the issue?

I called them. I was hoping for experts, but it seemed pretty much like a AAA style answering service. They wanted to make sure I was safely off the road and were happy to google my nearest dealer.
