Not sure why, but I've a feeling that tells me in all these years my plugged in Tesla was NOT a happy Tesla
What you are suggesting is along the lines of what happened in 2013 with the titanium shield. Tesla temporarily disabled low suspension mode via software update while it rolled out the shield solution. There was some initial outcry which quickly dissolved because Tesla was extremely forthcoming and Elon Musk communicated with owners.
Unfortunately, here we have a situation where Tesla removed 10% of owners' battery capacity without any communication whatsoever and without any reassurance that Tesla was working to resolve the issue. This is much, much worse than temporarily disabling low mode, compounded with the lack of communication and Musk's/Tesla's complete, utter silence on the issue.
There is only one logical reason for Musk to stay silent and not communicate with owners about #batterygate. It would be a game-ender for the company. That is the only logical reason I can see that would compel Musk's silence. Remember, we are talking about a man who generally cannot be told what to do and whose communication is difficult to restrain.
Musk has recently shown a disdain for government regulators such as the SEC, and openly disregards the rules set down by NHTSA regarding how manufacturers are to represent its safety ratings. Even if NHTSA were to open an investigation, which it has not yet done, I fully expect Musk and Tesla to challenge its findings and do everything it can to avoid compliance if it's an existential issue.
In the past I have given Tesla every benefit of the doubt. I've owned since 2013 and excused almost every misstep Tesla has made over the years. But I've also seen the company (and its CEO) evolve over this time. I've seen the dismantling of communication between owners and service, which was not unintentional. There is a method to Tesla's stifling owners in this way. If you make something difficult enough, you'll have a significant number of people give up and not even try. It all seems very methodical.
There was a time when we could escalate our service and vehicle issues to regional service managers. That has long since disappeared. Tesla service will no longer disclose contact information for anyone above the local level. This is very intentional and I don't think anyone need wonder why. It's now fairly obvious.
I wouldn't put so much faith in the NHTSA. If it decides not to investigate Tesla, which is still very much a possibility, there will be no published findings. There would have been no formal investigation. I'm not sure what information would be available to the public were that to happen, or if inside communications could be revealed through a FOIA request.
Has anyone filed with their State Attorney General on the basis of criminal theft? Tesla reached across state lines to essentially vandalize thousands of owners' vehicles. Doesn't this aspect make Tesla potentially liable for committing a federal crime?

Yes.
- Stealth SW upgrade removes functionality
- There was massive outcry and lawsuits threatened
- Tesla explained (eventually) themselves and their plan
- Most people were willing to give Tesla slack to work things out
- Tesla restored the functionality and fixed the underlying issue
I am thinking of having my attorney bring this up with the MA AG. That office loves cases like this.
I am waiting for all diplomatic channels to fail first. But we are very close to that point.
Another data point...
I am on 16.2 software and have been since it first released in May or early June. I thought I was unaffected by batterygate so far. After stumbling on this thread in June I have been following it daily, and recording data from scanmytesla as much as possible. I subscribed to Teslafi recently to gather even more data more often.
The issue has always been as the title has said, a "sudden" range loss. Well, I think there is also a gradual range loss for those cars that were not initially flagged by the software as "need to act now".
Here is my data...
I have been noticing my range decreasing over the last 2 months, not by much but by 1 or 2 km every week or so. I assumed it was due to temperature dropping outside.
My last full range charge was on August 2nd on AC, not DC charging. I had 390km range, 4.2 volts max, 71.4kwh (which is the same amount of range that I had for a few months, it was 389km in the winter, went up to 391km as peak in the summer).
After months of noticing my range gradually decreasing, I had to range charge yesterday for a long trip. At 100%, again on the same AC charging method, I am now at 385km range, 4.17volts max, 70.6kwh.
So I went from charging to 4.2 volts max and 390km of range to 4.17volts max and 385km range.
Again, not a sudden drop or a large drop yet, but perhaps those of us unaffected are getting gradual capping?

Maybe my reading comprehension is not so good, but I don't understand what you mean by "When I point out that is what they hope to achieve, not why they did it in the first place".
To save me searching back through the hundreds of pages, what exactly are you capped to and which battery do you have? I seem to recall this being a problem with the 90 kWh battery only and the rate was capped at some 80 kW?
I know if I paid this much money for a car and they abruptly capped my charge rate I would be up in arms. Tesla might get away with it on the Supercharger network, but capping your charge rate on Chademo chargers is not Tesla business.
Somewhere along the way things started to change. All the good people are gone, Guillen, McNeill, Straubel, etc. Nowadays, it’s a one-man show, although it mostly comes across as a no-man show. Very sad.
I have posted this 100 pages ago but I'm a model 3 owner and my battery capacity went from 100% at 20something k miles to a 8 or 9% loss from June to August/September around the time of that software update. A lot of other model 3 owners are seeing the same especially AWD owners as we didn't get the bump to 325 miles. My battery has since recovered to 6% degradation.
Anyways I'm guessing they did something to the BMS as it is odd that I got 100% all winter and started seeing degradation in the summer. Tesla says my battery is fine and blames it on the warm weather but I'm in Canada and the weather really wasn't that warm.

My battery capacity the big downtrend started at the beginning of June.
Actually, it has been their business for two years now:
If you fast charge, Tesla will permanently throttle charging
Same boat as you. I've lost 2.34 miles in three months (7/1 -10/1). 3500 miles driven in that time. 2.34 miles lost for 3500 miles driven is extreme. I'm very suspicious. I started logging with tesla fi to get documentation on it. The true range loss is much worse, as I dropped 5RM off the range over night one day and that's what spurned me to start documenting it. ~7 miles lost since January of this year.

Yes, I expect the service people and the customer support people to be able to answer service related questions.
They are the ONLY people we can talk to. They are the face of the company. They have had 5 months now to come up with a credible story.
Teslafi. It records every charge session and calculates charge at Target in miles/km divided by target percentage to get 100% equivalent and graphs that. Since I almost always charge to 90% I think that graph is at a minimum a good indicator of how my 90% charge has decreased over time.

To save you reading through the 6000 plus posts, there are two 'problems' running concurrently.
1. Capping of the battery (batterygate). This is where they have capped the batteries on SOME pre facelift cars with 60, 70 or 85 kWh batteries. But NOT 90 kWh. (This is the problem this thread deals with)
2. Strangling charge rate (chargegate). This applies to a much larger group of cars. (This thread does not deal with this problem, although there are many posts about it, as it is obviously closely linked). I have not heard that Chademos have had their rate capped.
My 70 kWh battery has been capped, from 70 kWh to 58kWh.
When I noticed the capping I asked Tesla why they had done it. They said for the longevity of the battery. That is NOT why they felt they had to cap the battery, that is what they hope capping will achieve. They have steadfastly refused to answer what made them cap my battery in the first place.

Same with mine, I've had a massive loss of charge. Not too sure what to do about it. I know tesla wont cover.
