How long do you usually have once you get the 12v battery has aged or degraded message before the car will have a problem? Got appt booked but ok to keep driving for how long?
6 months later I’m also now at 286mi range at full charge or 258 for the usual 90% charge.
For those that arrived here many months before me where has you ranged settled to now?
just to add another data point:
2019 3P+ with 3,900mi in Phoenix
Was getting 306mi range at full charge before sw 2019.40.50.1.
Now getting 301mi range at full charge.
I have a 3P. Car was in condo garage while I was away for 6 days. I left Sentry Mode on and lost just under 1mph as expected. I checked it in on it once a day and graphed it
Had the same issue when I upgraded my iPhone. I went into iPhone Bluetooth setting found the Tesla entry and told it to forget device so that it could re-pair as new.
