Charging error (All 5 segments turn RED) HVB Module failure

Are you getting the service done at Madden Ford?

Yes I am. Where I bought it 11/22

That has a cell failure written all over it..

Looking forward to a follow-up and quick successful repair.

AAA towed it to the dealer this morning. Getting into tow mode neutral was fine. Arrived at dealer and The driver starts unloading and the emergency brake is engaged. I tried to disengage and the truck seemed to lose its mind with every effort to dis-engage. Eventually the the truck stopped responding completely and the dash went black and would not wake up. The driver had seen this before and manully opened the frunk and attached his jump box to the 12 volt battery. Voila - truck wakes up and allows us to put it in neutral and release the E-Brake. As I write this I am home waiting for the word on the ($399 unless its the battery system covered by warranty) diagnostic results.

Happy to stay on this thread or start one fresh.

You can continue documenting your experience here, it's not a long complex thread yet.

I debated with myself moving your post here

Powertrain Malfunction/ Reduced Power but figured we can leave it here until you have better information about the root cause.

Ford will not sell you an extended warranty on a Lightning battery. I called and asked. It seems that after the 8 year/100,000 mile warranty ends you are on your own if a battery module needs replacement. While 8 years/100,000 miles seems long, I think most ICE F-150s have life expectancies much longer than Ford’s Lightning battery warranty.

I believe I'll trade in just prior to my 8 year warranty.

The BMS continuously balances the cells. They also absolutely would have been balanced when manufactured.

There's obviously a quality control problem with these modular failures.
When assembling battery modules the cells must match as closely as possible else excessive cell degregation will occur. It's possible that's what is happening here. Whatever, It is definitely a QC issue. Driving and charging had nothing to do with my 3 modules failing. Mostly 55 mph & city driving and max charging done with Ford 0 amp charger and 30 amp charger. No DC charging.

Sadly, I have come to the same conclusion.

I'm 75, I was hoping this would be my last vehicle. Now it looks like that won't be the case. I only have 5 yrs left on my warranty. Mileage isn't a problem because in the past 3 yrs I've only driven a little over 23k miles.

Yes, for the battery the 8 years/100k miles and 70% capacity loss is the industry standard, and my Leaf had the same if I recall.

I've had my Leaf since Dec 2011, light use and still has 80-85% capacity.
Just a short hop vehicle - nice when gas prices spiked and driving my Ranger was costly.

If after 8 years the Lightning battery fails to have 70% capacity I'd be surprised.
But if it has 84% that would not be a surprise since 2% loss per year is typical from just age.

I do wonder about folks that fast charge all the time, will they fall below 70% after 8 years?
Time will tell when 2030 rolls around.

We do read about other things besides the battery failing here on the threads, that would be covered only by the 3year b-to-b warranty.

Where there is a manufacturing defect that doesn't appear until AFTER the warranty expires, there are sometimes other remedies, lemon laws, product liability laws, and other legal avenues depending on the facts.

It cost me $3200 but I extended my B to B to 8 yrs/ 100,000 miles

For $640/year (about $1.75/day) not a lot for peace of mind.

We all hope we never have to use mechanical breakdown insurance, but entropy rules the universe and human error is ubiquitous on planet earth.
