I'd be less likely to do this if you hadn't made repeated posts on this topic. I'm just going to ignore your almost certainly not serious threats of legal action. I respect you enough to not take them seriously.
Given your legal threat I doubt Tesla can do anything for you now. Even saying sorry might be used in court against them as an admission of guilt. I'm sure lawyers will show up to debate this as this sort of issue gets debated endlessly as to if you should or shouldn't say sorry.
Statements of update on the status would probably imply that it's behind schedule and trigger a wave of media attention about how Tesla is falling short. Silence results in a few people like yourself grousing (feel free to object to that word too). But probably results in no real consequences for them.
Extending the warranty probably won't happen unless this becomes a publicity issue for them. Plus it wouldn't do anything to sell more cars because the only benefits of that would basically be customers like yourself that have cars with autopilot that are waiting for the update.
Would you actually seriously accept a refund and disabling of TACC? I have a hard time believing that's what you really want given your complaints before even TACC was available.
I'll point out that Tesla didn't do gestures of good will en masse for customers who complained about missing out on autopilot hardware. They might have done things, but as someone who might have been a beneficiary of said gestures, they have never suggested that the pricing on my trade-in was because of the situation. So I can only guess.
Of course Tesla has not done anything to mislead you. You've decided to anticipate the features well ahead of their availability and that your anticipated date has come and gone now you're frustrated. This of course is a normal human emotion. But it doesn't mean that Tesla wronged you. They never promised you anything on a specific time frame (MVPA says that nothing Tesla employees said to you is binding unless it's in the MVPA, see below quote).
I predict that you get absolutely nothing other than the feature being delivered to you when Tesla is ready to deliver it.
Edit: I'll point out that is exactly what you go for the next gen seats. Which is something you did have a reason to object on the delay. Because they were actually supposed to be on the car at delivery.
I think you definitely need to take a step back and look at what you're saying here.
First, I'll just nitpick one thing: the MVPA. A line item on my MVPA specifically says
"Tech Package with Autopilot." Nothing on my car can do can be defined as autopilot by any stretch of the definition. So if the MVPA is the final word, Tesla is in trouble because it definitely doesn't say anything about this feature not being available until later.
Next, I don't see any legal threat anywhere. Reserving the right to pursue legal action is hardly a threat. If Tesla has done no wrong here they'd have nothing to worry about from me anyway.
As for accepting a refund and disabling TACC, if that were actually an option I may have to take it on the principal of the situation, because TACC alone is not a $2500 line item. I highly doubt they would offer this to anyone, but it would definitely be the right thing to do for them to offer it with the specific condition that the feature can be bought and activated at a later date (at the same $500 penalty offered new buyers).
Gestures of good will for people who missed autopilot hardware? How is this comparable? They got what they paid for. Those who got autopilot hardware early got what they paid for and more. P85D buyers like myself specifically bought in for autopilot and paid for this feature. This is apples to oranges.
As for extending the warranty on the autopilot steering hardware this is most certainly the right thing for them to do. The hardware is impossible to utilize through no fault of ours. What if I had 50,000 miles on my car, got the autopilot update at 51k miles, and the hardware for the feature I paid for at delivery doesn't work at that time even though I've never been able to use it since delivery? That's my fault and I have to pay? Come on now. (In this hypothetical I'd think Tesla would work with you, but at say 25,000 mile activation and 51,000 mile failure... a gamble.)
Statements on the status of autopilot lane keeping should have been happening with or without me "crying" and would have gone a long way to build credibility, be it good or bad news.
Next gen seats is pretty much the same situation as this, also a paid line item on my MVPA. If Tesla had taken this long to deliver my next gen seats I would have an equal gripe with them about it. Fortunately my car was in fact delivered with front next gen seats, surprisingly, and I was updated constantly on the status of the rear seats. You won't find a single post anywhere where I'm "crying" about the rear seats, mainly due to the unsolicited and appreciated periodic status updates on the issue.
All that said, regardless of the definition you posted it is pretty well known that using the term "crying" in reference to an adult is belittling and disrespectful. Grousing is generally for complaining with nothing at stake or very little at stake, if I recall correctly, which this certainly is not. (Just checked the definition to be sure, and I don't think anything about a $135k vehicle could really be considered "petty".)
