My 2014 Tesla model S P85+ had 64,000 miles on it in this summer (2023) and the battery died. I thought they were supposed to last at least 100,000 miles. I saw a comment by Elon Musk saying they would last between 300,000 to 500,000 miles. Having to replace a battery after 64,000 miles at a cost of $15,000 seems insane. Has anyone else experienced extremely short, battery life? Any reasons why a battery on a car that is lovingly driven would die? Have not done, extreme overcharging, left it outside in extremely hot or cold weather, or anything else I can think of that should’ve heard it. Technicians just said, “oh, sometimes this happens. They don’t have a guaranteed mileage life “. No help..,

Dead battery after 64,000 miles!

Can you explain "dead"? What was the % degredation before this happened? A 2022 MSLR has a drive train and battery warranty for 8 years or 150,000 miles, whichever comes first. Even if the car had zero miles, the battery still has a limited shelf life due to calendar aging. What's the warranty for your 2014 car say?

I'm sorry for your loss. But this is the danger/downside of being an early adopter. I think Tesla learns from their mistakes and batteries on newer cars have much longer lives. If a failure mode takes 7 or 8 years to show up, it's hard to know about it before then.
I know it doesn't help you at all but I'm amazed by how much they were able to get right without decades of trial and error.

Unfortunately, the earlier model has a flaw where moisture can get it and leading to premature death. It's not related to the mileage of the battery.

Vendor - Preventative Maintenance regarding Battery Failures in early Model S vehicles (2012-2014)
There are some definite trends with early battery packs failing in earlier Model S vehicles... from day 1 builds up to about Q4'2014 and some even Q1'2015... and any cars that have had Tesla-refurbished packs installed. The issues are all pretty much the same thing in one form or another...

The technology isn't perfect but high demand, high price.
There's alternative repair shops but I haven't heard of anything better than the Tesla 4 yr warranty.

My 2013 died a month before warranty ran out. Several bad modules caused not to charge. I got remanufactured pack. If, if your warranty is up? You can get a replacement easy under 10k from several shops. They told me a few months ago a replacement was 12k with 4 years warranty. I had a 2012 , A pack, it has a B now.

No issues with degradation before as it took and kept a charge well. Kept charge to anout 70-80%. Seemed to get just as good performance as our 2021 model 3. Warranty had run out 6 months earlier. I was the original owner. Literally, worked perfectly then wouldn't turn on.

No alert. Simply parked and next day it wouldnt turn back on. Message said something like charge too low to turn on system.Which alert(s) did you get?
the Tesla repair shop innAustin didn't mention any moisture. They just said battery sometimes failed even with low mileage and that there was no guarantee how many miles it would last.Unfortunately, the earlier model has a flaw where moisture can get it and leading to premature death. It's not related to the mileage of the battery.

But, seriously, 64,000 miles over 8.5 years running kids to school and getting groceries shouldnt kill it.
Here's FAQs on BMS_u029 and BMS_u018 Specific
yes, battery had just passed the 8 year mark. Tesla repair shop said the batteries can just go out without warning for no reason. That sounded pretty lame to me.

That is an alert. It should be in your notification history. It would be nice to take a picture of it and post it here.

Are you’re sure the HV battery is the problem? If the 12v shorted you’d also have a dead car. Or if your 12v charging system broke.
I second the request for a screen shot of the alert \ error. I assume your car is plugged in.

While it will not help you with the issue, it is probably another issue than the battery cells being worn out.
The cells them self might be in good shape, but the could be an hardware issue with other things inside the pack, or very likely the 12V battery.

It seems like you already take it to SC or somewhere else ? Do they give you the details or error codes? The first gen system is not as robust as the later ones. There is a similar thread and more like what you described, whatever Elon says, take it with a grain of salt...
Tesla Model S 2014 HV Battery issue
Hi, I have a Model S 2014 P85+ Last Monday I was driving it near from my house in Guatemala, but the car suddenly stoped with the warning: “Unable to drive, supply voltage too low”… I thought that would be a 12V battery failure, so, on my own, I replaced it for a new one. Yesterday, after...

My 2021 model 3 battery just died with 36k miles driven. They are putting in a refurbished battery. Not happy at all.
