Wiki Sudden Loss Of Range With 2019.16.x Software

I guess I should have been clear rather than let folks interpret my request from the graph.
Mv differences showing weak strings will be almost non existent when fully charged. The lower the soc, the larger the spread will be. Normal at 30% is about 5v.

I just found this thread. I've been having this battery capping issue for months now, and I started noticing it right after the summer break because the route for my son's school was always the same every morning. He started going back to school, and my charging frequency started going up and my range down. Less range and it felt like less power too. My route was always the same for the past 2 years, and I knew something was off.
I never imagined Tesla would cap the battery though. I'm on a P85+, I just had a 90% charge, and I drove conservatively @60mph freeway with slow acceleration, to test if it was my driving was causing the problem. I got 162.8 miles with 8% left with an average of 307 Wh/mi.
Man, this is pretty frustrating to hear that Tesla was the root cause. I've added a NHTSA complaint, and hopefully Tesla will make it right.

So Tesla just texted me and asked me to update my "very old" firmware first.
I have a sneaking suspicion that if I were to do that the battery message would disappear and the current condition would be treated as normal but with reduced range, power, and charging.

That does not look right at all. Were it not for my string 58, my mv difference at 38% would only be about 4 mv.
They just sent me another text saying they won't diagnose my car unless I update the firmware first.
They are on to you! That's is total BS! F- you Tesla im done with your sh*t. Djras can you make them bleed for us!!!
Edit: some word check
Honestly now, could there be a direct connection between your statements on this thread / TMC, and Tesla's 'demand' that you update the FM?
Refusing to update may be used as an argument against honoring the warranty on your battery, but contractually they cannot force you, can they?

They CANNOT legally require software updates for warranty coverage.
Don’t the newer warranties have that exact clause though? I think my Model 3 warranty says that. Guess Tesla has “learned” from these older cars, since the old warranties don’t say that.

When I mentioned the significant increase in Vampire drain, they told me they 'couldn't' pull the logs unless the car was on the latest version of software. Really!?!
Apparently when they pulled the logs the last time, on the same version, it was something of a miracle.

The Warranty was updated to include that owners had to update else it would invalidate the Warranty. However the Warranty that was extant at the time we (batterygate affected owners) all bought our cars did not say that.
