My car was completed 2/15/22. I am assuming I need to recalibrate the BMS, as it says I only have 278 miles of rates range at 90% charge, which extrapolates out to 308 miles as 100%. If this is true, it is worse than my previous battery before failure. Remanufactured Battery part number is 1107679-01-E

HV Battery Failed After 2 Years.. Months at Service Station?
- Thread starter Travelhead
- Start date
What was the estimate at 100% for your failed battery? It is unlikely that a recalibration will change the estimate much on a freshly refurbished pack.
314, the day before failure. Not much, but considering the rated range on it new is 335, it all adds up..

So just got my car back today. 5 days short of 2 months. Last night I checked the app and driver's door and frunk were open. I think they were checking for the Frunk recall issue at the same time since I asked them to do it. Then it was plugged in and was being charged from 7 PM till about 8 AM today. At about 4:30 I got 3 rapid messages on the app that the car was ready to be picked up and I headed right over to get it.
They didn't even bother washing it. It had 2 months of dust and dirt and bird deposits on the car. Drove it to the carwash and will be watching the battery closely. It's great to have the car back after 2 months, but I'm really doubting this whole process. The repair manager said that they're getting lots of HV Battery replacement repairs and they're telling everyone 2 months is normal.
This is not a phone so if the battery dies or gets to this condition, at the worst case scenario, you just cough up another $1000 and get a new phone and sell the old one when repaired. We're talking about $110,000 car with hardly any parts available for repair.
They "detailed" mine, which was just a quick exterior wash and some tire shine. I'm running my battery down and going to charge it back up to calibrate the BMS and see what it shows for range. I log all data via TeslaFi and have for years, so hopefully I at least get the same range as before it failed, hopefully more.

I just had a battery failure at 65xxx miles. On a ‘20 LRX. Battery is being replaced on warranty. They’re saying they already received the battery-
(BATT,100KWH,SX,REMANUFACTURED,RAVEN(1107679-
01-E)
And if they’re right and I get the car next Tuesday; that’s an 8 day turnaround. Pretty impressive.
And they gave me a loaner ‘23 model S. What a car…now considering trading in wife’s 3P for a new LRS; 3 years free supercharging is pretty sweet.

That’s great to hear. I’m so happy that Service’s experiences are sometimes not so bad after all. I also hope that my new range is at least as good… I hardly had any range loss from new. So I’m really hoping for greater than 300 miles of total range. Either way, I’m hoping I never have this issue again and grateful to have it happen while still covered under warranty, and not while away from home on our road trip.
I shared my full experience in the investor forum here.
TLDR; also quick tow (free with tesla insurance roadside). And this all happened after a 4400 mile 6 day cannonball road trip to starbase!

My battery failed again last month, one year and 22k miles later. "New" one has ~20 miles less EPA rated range, and it is obvious they have software locked it. Trying to get it resolved is an exercise that is trying my patience. Someone from Tesla called and tried to tell me how it needs to learn my driving habits, which is total BS as the EPA rated range number is not affected by that. I'll entertain their ideas about charging and such for the next few weeks, and then I will escalate this under the terms of the warranty given to me. The only good part is that they did have another battery in the car in a few days. Currently at just over 85k miles and on battery #3 with a max EPA range of ~297 miles at 100% SOC. 2018 S 100D.
On a side note, they refused to tow the car in without me paying for the tow, even though they knew it was a battery failure from the logs and that it was going to be covered under warranty. I ended up paying for a AAA membership and towing it in a few days later once the AAA system allowed me to. (48 hour wait)

It is well known that Tesla will software lock your replaced battery to your previous useable capacity, they did it on my previous unit.
Why would they do this? Out of spite? Do they just want to make sure it's a poor experience?
do we have actual evidence of that or are you working under the assumption that your refurbished battery was supposed to match the epa range of your original battery?
I am not entitled to full new capacity as new, but at least the same capacity as my previous battery before it failed would be fair.
Per Tesla's warranty in the owners manual:
I am under the impression that they do this to give the battery a larger buffer zone, but in my view it is just to upset customers. Why they would purposely lock the customer out of some of the capacity of the replaced battery is a mystery to me. It not like I purposely break the batteries and want to have a broken down car.
And we know your Wh/mile was the same before and after the repair? Doesn’t the car do this ‘guess-o-meter’ math in real time, along the same lines as the “zomg I recovered range” threads in the model 3 subforum?
