I'd like to see more data...

For example, if you get 10 tesla cars of the same model, do the ranges differ?

If you get 1 car and 10 different drivers, do some drivers get the advertised range while others don't?

If you disassemble the battery packs, do you find some bad/degraded cells in cars with reduced range, or is this a design fault?

Do drivers that have trouble have inefficient mods, like roof racks, big wheels, etc?

I don't think you need more data. Tesla had a team of people "managing" this issue to relieve demand on their service centres. What more data do you think would be useful to clarify Tesla's actions?

That statement alone sounds good to me... If there is no repair action that can fix the range issue on these cars, then it is a waste of everyone's time to go to a service center only to have a service tech poke the battery and realise it's fine. What are you expecting them to do when you arrive? They certainly won't be taking out battery cells and putting them under an electron microscope... And measuring battery voltages and currents is already done automatically by the computer.

There is very little you will diagnose on a modern car that the onboard computer isn't already aware of.

Therefore... the idea of a team of remote diagnosis people to fix most issues without a service appointment makes perfect sense.

As does the idea of having the analysis done automatically beforehand so the human doesn't have to wait.

Except they did not fix anything. The battery readout was lying as so ordered by Musk. This caused people to complain, wanting it fixed. Instead of fixing it (in a service centre or remotely) they lied some more. What's so hard to parse here?

I think the 'fix' was mostly checking that the car was working as designed, then calling people like this hn commenter[1], and educating them that slow gentle driving is how to get the estimated range, not aggressively braking and driving 90 mph with the AC on max, windows down, and the trunk loaded with 2000 lbs of junk.

The point is that "as designed" was really "designed to mislead" aka "lying", and they got caught red-handed.

They got caught red-handed using EPA-rated range in the interface? The number that your Government declares to be the correct one? Oh no.
