Do *not* perform any OTA installs with a battery warning. During the install process the DC-DC converter will not keep your 12v battery maintains and it will be working hard on its own. Trust me on this. Get your battery replaced ASAP.So I got the warning that the 12v batter needs replaced. Does this limit supercharging. I’m at my usual supercharger and I’m on charging at 57mi/hr. Also it will not auto park anymore sine the warning came up.
Autopark might be affected.
Supercharging is probably slow because the pack is cool, should speed up as it warms
I don't know if they have changed the algorithm in the last few years but I tried this in about early 2018 and it would always fail the update. I called tech support (when they actually answered the phone in those days) and they stated the car would not update when a warning was posted.Do *not* perform any OTA installs with a battery warning
It’s 55 degrees and the car has been driven for 1.5 hrs? I wouldn’t expect the pack to still be cold?
Good point. Actually I recall that message now and they probably added it for clarity/safety. In the past couple of weeks I had a battery that was *close* to going bad and getting a message. My OTA failed. I jumped the car and was able to complete the OTA. Tesla support said my 12v was OK and not giving messages that they could see from their end. However, the next day while supercharging we received the message. ie.I don't know if they have changed the algorithm in the last few years but I tried this in about early 2018 and it would always fail the update.

Sometimes a particular supercharger cabinet has issues. Try moving to another one and plugging in there period that often solves the problem.
One advantage of my old 85 is that it charges so slow now it really doesn't matter if a cabinet is itself slow!

It was a bad cabinet. I wish Tesla would have a message that alerts you that you're charging on a bad cabinet with reduced speed. I went to a different location just now and supercharging worked just fine.
I just got the same 12v battery warning this morning too for my MX 100D 2017.
The service was scheduled, but was delayed for 3 weeks because of back order on parts.
Is it safe to drive with such warning? I guess not, then 3-4 weeks wait is not really acceptable.

The part (12V battery) is on back order so no luck.I just got mine replaced today with mobile service. 3-4 weeks is not acceptable. Did you try calling the sc?
