The main 400volt battery pack. The 12volt battery is for auto style stuff and is kept topped off with a DC-DC converter that is part of the car.What is the "Traction Pack"?

If you need to do this, then the charging system in your ICE is busted, plain and simple. A properly functioning car, driven frequently, should not need its battery topped off.I normally put my ICE cars on a trickle charger once a month or so to get them topped up (which is good for AGM and Lead Acid batteries
Yep, right up until you fry the diodes in the alternator. Don't do that! :wink:The one nice benefit to ICE cars is that once they are started, generally speaking you can even unplug the 12V battery and the car will keep running
I'm glad someone else said it... I was biting my tongue and just couldn't bring myself to do it! :biggrin:My guess is there was a 'One Direction' song playing and the car just couldn't take it. LOL
Supposedly Sears Diehard Advanced Gold AGM (not the "standard" gold, which is Flooded LA) is a re-badged Deka AGM made by East Penn, while the Diehard Platinum is a re-badged Odyssey. Both are excellent choices. I run the Advanced Gold in my Mini and my 911 race car (the Platinum is not available in those sizes), and Deka AGM's in my boats.I have replaced all our cars batteries with Odyssey Batteries - haven't done it in the Tesla yet because it is so new..

Why won't Tesla take some of their cells and MAKE a 12-volt battery out of them? It's been done:

Again, as others have noted, it doesn't look like the 12V battery is the problem on my car. It is most likely the contractors which are under active recall right now. I am not sure why I would have faulty contractors on a car that was delivered just a few days ago. But then again I am not sure why I don't have the seats that I ordered and why random people got heated steering wheels and I didn't.
Tesla is a mess. I think our "black-hole" P85Ds were cobbled together with any available parts and duct tape. They are all Frankenstein cars sold at full price. I really should have listened to my brain and cancelled both cars. I think people who will get March builds will be very happy. Expensive mistake.
I am sure our Frankenstein cars will eventually be fixed under warranty but it will not be fun getting tow truck rides every few weeks to the SC.
Tesla needs to learn how to under promise and over deliver. Today, they are squarely in the over promise and under deliver camp.
Too bad.
I find it amazing how many people are jumping to conclusions about what is wrong. While it's true that there was a clunk you can't determine that the traction pack or the contactors had a failure based on that. Any situation that causes them to open suddenly is going to cause a clunk. Just a few months back someone on this forum had a bad 12V battery on a car with around 100 miles.
Also the presumption that the cars are poorly made and that people will be going into the shop every few weeks is premature. Maybe you're right maybe you're not. But what I have seen so far is one front drive unit failure and an unknown problem (possibly 12V battery, possibly DC-to-DC converter, possibly HV contactors) on P85Ds. No matter how reliable the parts are there are going to be parts that fail, this is the nature of the way things go.
What precautions should I take???
It seems likely the -12 C weather you had at the time was a factor for both the 12V battery and the main battery pack. The dotted limit line in the regen region of the speedometer suggests that the main pack was quite cold.
He was instrumental in guiding the tow truck driver and I to get the car into neutral. It wasn't trivial to figure it out.
Osama, saw this on COPA this morning.
How did you know to remove the nose cone to access the 12V battiery?

Holy crap Osama. Glad you and son are OK and the wife was not driving. Stuck in an intersection is dangerous to boot. This now has me even more leaning towards cancelling my potential Frankenstein cobbled together vehicle that is lounging in the Fremont back lot.
The music is Slacker "Today's hits". I guess my wife picked when she last drove the car.
