I setup a service visit to have a look at my Battery because I've lost 31 miles of range after 15 months or 14K miles of ownership. I have a 2020 performance 3, received a message from Tesla support saying that's normal and that they'll cancel my appointment. Is 31 miles range lost normal? I'm only getting 268 @100 percent.

Nope. Not normal.

That being said, have you run any diagnostics to see if the capacity of your pack is truly reduced?

Or do you just have a heavy foot?

Do you charge to 90% so the batteries have a chance to balance? Do you occasionally fully charge and run low so the BMS has a chance to know the top end and the bottom end of the battery? I have lost 11 miles of range over the last 65,000 miles.

30 miles after almosy 2y and 20k miles is normal. Slightly below average.

Tesla will say its normal until you hit 30% degradation unfortunately

No that's why I'm trying to setup an appointment to see what's going on.

Yes charge to 90 normally, 100 only while traveling.

Then I agree something seems wrong.

It's not the battery, it's the BMS giving you those readings that look like a loss. There are tons of videos about this and what to do to get the range back.

and unfortunately they are all false/wrong.

Tried the drain then charge to full trick and loss 5 miles. I've read the Tesla owners manual and there's nothing there about battery reset. But there's a female YouTuber the stated after she loss mileage tried to do the reset and nothing happened that (Tesla) reset it for her and it's been dead on every since.

Sucks that Tesla won't help you, but I would highly recommend this post. Follow the steps to give the BMS a chance to "see" the voltage at lower and higher states of charge and you may see a different range estimate once it's done that. Hopefully you get some back, as the original poster here did.

what's the issue? 30% is the threshold. nothing else is specified in their warranty.
