Oh, how I wish my pack could look like this! Mine is down to 80kWh total pack energy, even after the SC pushed a new firmware to my BMS, as well as reset it.

Please take the "Like" I gave that post in the spirit it was meant... That being that I am totally disgusted by Tesla's response to this.
I'm a Tesla fanboi, to be sure, but I'm also not hesitant to call them out on their problems, and right now Tesla has a huge quality control and customer service problem. They need to be called on the carpet for it, and they need to fix it.
You've been more than patient with them, and have given them ample opportunity to "do the right thing." It's now time to spread the information out there far and wide. If it were me, I'd call up every consumer advocate you can get to listen to you, and have them tell your story to as many people as possible.
C'mon, Tesla. It shouldn't take so much work to get you to do the right thing. This kind of crap is the ammo the FUDsters are looking for, twofold: 1. The quality control issue; this pack never should have made it in a car in the first place. 2. Tesla is NOT doing the right thing in how they are dealing with it.
Wow... I need to go have some coffee before I start snapping keys off my keyboard.
Really appreciate you keeping us up to date on this, and doing so in such a level headed manner... it would appear that I have the anger part of it handled for you.
The imbalance is 80 millivolts, which is much better than the 390 millivolts at low soc.
The Full pack is only 80.8 KW, which is almost 20% less then normal.
My guess is there are a one or more faulty modules, which hold less charge than normal, causing the pack to not fully charge, because they hit the high cutoff voltage of 4.2 volts earlier than the other modules.
If the faulty modules were still in good condition, the BMS should be able to correct the imbalance after a few discharges/recharges.

Or he can talk to Tesla and ask for new battery or car since none of theirs work arounds didn’t fix the issue. I don’t understand the mentality of going around wasting energy and time with spreading unfortunate experience.

Mine just gets worse per discharge, sadly.
I'm hopeful I have (the process started on) one of these happening this week, but... that's just hope - likely far from reality!

Whoops. Is this only on Plaid models? I tried the DynoTest and all I got now is.... "Service Required". That was fun...
Going to try a Hard Reset when I get back to the car.

Just run dynotest again and it should go away. Otherwise just leaving the car and coming back fixes it.
Datapoint: new Sept build plaid showing 97.4 full pack energy

Very nice. I think the highest I've seen on TMC is 98.5kWh, and the lowest "working" Plaid to be around 94kWh. The defective batteries have shown to be around ~70-80kWh (like mine).

Are they still not repairing or replacing these packs? What is their excuse? Software update coming soon?
Yeah, I really think I won't bother going through with my LR order. A few downgrades from my P100D and their QC seems to be even worse than my car.
All three people report that Tesla is replacing their packs.
Yes, as one of the three, I can confirm, all 3 of us have new packs coming.

I wouldn’t delay your order over a few of us with these issues. As I’m aware it’s actually four of us now out of many thousands of LR/Plaids.
It's not just the posts here about battery issues, there's been plenty of issues on Reddit, including people with shutdowns and having to be towed to service. Lots of other quality issues with paint and handles. Just seems like waiting an extra 6 months makes sense.

Oh there’s zero question these cars are rough around the edges. But life is short… and that’s what warranties are for.
Update. I've left the old software for a while and watched the data in dynomode and the full pack reading has ranged from 97.9 to 95.9. No discernable pattern.
Wanting the better turn signals and sound system so abandoning the old firmware with informative dynomode.
