The only other thing Iād check thatās 12v related is to make sure the connections to the 12v battery are tight. Even slightly loose and that also causes issues.
Wow 2nd Lightning that went brick on you? It does sound like a weak 12v battery issue. Got any aftermarket accessories using 12v power? Or doing short infrequent drives? Those two things can result in drained 12v battery.
Iām a little confused by all the Donut hype because apparently China is already rolling cars out with solid state batteries as prototypes? https://electrek.co/2026/02/11/solid-state-ev-battery-standard-china-2026/
Nice to see itās fixed. I would also recommend putting in a quality memory card (like Samsung or similar) and ditch the one it came with if you havenāt done that already.

Also just got this this morning. I was trying to use a public level 2 charger in town and the truck would keep refusing to handshake with the EVSE and stop the session. I got frustrated and started driving away and then I see the āupdate successfulā message on the screen while driving. I then...
Curious if thereās a definitive part list out there of whatās considered āEV powertrainā for this reason. I agree that anything that has to cool or warm the HV battery is to me āPowertrainā but weād need to know what the Ford lords say.
Is the PTC heater in a hard to reach location or basically under the frunk tub somewhere? Just wondering for years down the road (hopefully years) when I may have to DIY replace it. Does it also require a coolant flush when being replaced?
Do you have phone as a key (PAAK)? And if so, is there another phone paired to the truck (spouse) that is at home? The phone passing near the truck (50ft or less) will also trigger the lights to come on.
I just hope Ford is wise enough to plan and design the next Lightning so that it can be either fully electric OR with an onboard engine generator, using the same assembly line.
No one knows how the political and technological tides will shift over the next 3-5 years. They have to be ready for...
