I've read different stories about dead 12V batteries dying. It is nice to hear there is actually a warning about decaying.My warning message that the battery must be replaced soon. How long before it actually dies? My appointment to replace it is in 6 days.... Thanks
Thanks. Mine is 2014 with 73000 miles.There isn't always a warning.
When mine died, it was sudden. Worked fine in the morning, dead as a doornail at lunch. This seems to have been fairly common in the early 2018 builds, probably due to a bad batch of batteries. For normal battery wear-out failures, the battery dies much more slowly which is why Tesla can warn you in advance.
Failures can be random, so be prepared, because having to stop somewhere inconvenient at a bad time is you know, no fun.My warning message that the battery must be replaced soon. How long before it actually dies? My appointment to replace it is in 6 days.... Thanks
Mind if I ask your vin ? I have a 2018 also...There isn't always a warning.

If this was a question that could actually be answered, the warning would be "you have xx days, xx hours, xx minutes until your battery dies," rather than the current wording. And if Tesla can't put any more of an accurate number to it, I don't think us forum jockeys will be able to do much better. I'm not trying to sound like a jerk here, it's just the way it is.How long before it actually dies?
Sept 2018 build, and 12v died today with no warning, other than rotten egg smell. Ironically a mobile tech had literally just swapped in a new charge port about 2 hours earlier.There isn't always a warning.
