Have been a MS 90D owner for 18 months now and have loved every minute of owning the car. Recently I have noticed what I mentally thought and in reality experienced was battery degradation. Every Friday and Sunday I have a 125 mile out and back road trip I need to take and previously had no problem completing on a full charge (normally only charge to 85% except for right before these trips) but the last month or so I see my estimated arrival to be 48% and return of -7%. While I am normally able to recover some I definitely have needed to supercharge just a but to make it home with 10-20% (for health of the battery).
Now for today.... I wanted to attempt to recalibrate the battery so I drove the battery down to 8% and started the charge at 11:#0pm last night to it would be ready for my trip. I checked this morning as everything was good until I checked closer to 90% charge and it was trickling at 2Kw and 7/40amp... it then stopped at 92% with charging complete. I lowered the charge % and then raised again and it tried for a minute or so at 2 kW and 10/40amp until it slowed down again, raised again, lowered and on and on for a few cycles and reach 92% with charging complete.
I called Tesla and they say they don't see any warning on their end. They suggested I "Power Off" via the settings screen and try again but other than that they don't see anyhting wrong. I did do and drove for a few miles and attempted to recharge and the same exact scenario occurred.
Do I have a major issue? Could one of the packs by down? When going from 8->92% it added 68kWh which would equate to approx 81kWh battery which is unfortunately close to inline with what a 90D should have.
Thoughts? Suggestions?
As always, thank you to the TMC crew for the help and advice!!!!
