That is the standard boilerplate for all range estimate questions -- probably a newer employee just going down the list of faxables (and possibly ignoring what you wrote, sadly; we've all been there, and sadly not only with Tesla).
It usually takes quite some persistence to have them go beyond_ that -- but they did offer a service centre appointment (where at least you have the opportunity to be more specific).
We have found that in cases where the battery is consistently charged to a lower state of charge, between 60-80% capacities, estimation becomes less accurate and tends to underestimate the true capacity of the battery. The result is an incorrect reduction in the displayed range estimate.
What in the world is this supposed to mean? Is there any other tricky explanation they have not pulled on us? Enough.
We have a saying in Scotland that describes this, exactly.What in the world is this supposed to mean? Is there any other tricky explanation they have not pulled on us? Enough.

Alas, I live in fear of the Moderators.
Yes, I visited one last Week in San Jose. 2012 S 70 lost 10% range overnight.Question. It has often been mentioned on here, including by myself, that heavy Supercharging is not the trigger, citing examples of people that have Supercharged to excess, and topped up to 100% frequently (such as taxi drivers) who have not been affected. Are we 100% confident that there are such examples from owners of pre facelift, 350V (85, 70, 60) battery cars?
As a side note - and this is more out of curiosity - how is this actually affecting people's daily lives? I'm seeing range drops reported like 10-15% (for example, David Ramussen: 247->217mi). Were you guys actually charging to 100% daily before the drop?
Am I missing something? Is this just about trips?
- If so, then your batteries should be degraded even if there were nothing wrong with the pack, and it'd be your own fault. Everyone knows (or at least should know) that you're not supposed to charge to 100% daily unless you have absolutely no other choice (wherein even "slow" degradation will eventually ruin things for you).
- If not - if you were being responsible and charging only to 80-90% daily - then just change your daily charge to 95-100% and you've got your daily range back, and your level of stressing your batteries is exactly the same as it was before the update, because you're charging to the exact same voltage. Only long trips are affected.
Excellent!Yes, I visited one last Week in San Jose. 2012 S 70 lost 10% range overnight.
How about this one:What in the world is this supposed to mean? Is there any other tricky explanation they have not pulled on us? Enough.
I thought initially, it would be pretty easy to accommodate the capping, by charging up a bit more to recoup the lost range.As a side note - and this is more out of curiosity - how is this actually affecting people's daily lives?
Was it actually a 60 kWh pack?. There was no 'S 70' in 2012 (the 70 kWh pack wasn't introduced until 2015.)Yes, I visited one last Week in San Jose. 2012 S 70 lost 10% range overnight.
I would normally charge to 89% and only charge to 100% if needed to get from a supercharger at point A to a supercharger at point B. I have been directly affected by this problem.
My car consistently charged to 227 miles at 89% (about 256 miles at 100%). I know this is accurate because I had to make a 250 mile trip between chargers, charged to 100% and made the trip with a few miles (about 5) to spare.
On June 19, my battery had a 74kWh capacity. On June 20, the firmware in the car was updated and the capacity immediately dropped to 70kWh and continued to dropped to 68kWh in less than 2 weeks from June 20. I asked the Florida service center to check the battery. They responded the battery is fine and the capacity loss and range loss is normal degradation, even though it occurred suddenly. They also said my battery is better than batteries in other cars of my age (2013 P85 with 60k miles). This is obviously false as my range is lower than other cars. My car’s range has dropped to 199 miles at 89% charge, a 28 mile drop. 100% charge is now 219 miles because the car now only charges to 98% maximum. Since my car’s actual battery consumption is more than 300 wpm (it’s lifetime average is 345 wpm) going further than 150 miles on a full charge is questionable.
I drove from Florida to Boston and nearly got stranded. With 28 miles to go to the next supercharger, the car said I had 14 miles range left. I had to drive at 45mph, with the last few miles being driven at 25mph to reach the charging site. Btw, I normally add 50% when charging to add a safety factor. That is, if the distance between two chargers is 100 miles, I charge to an indicated battery range of 150 miles. I stopped at a service center in Maryland and had them check the battery again. They replied, without testing the battery or checking logs, that Tesla intentionally reduced the range to reduce the possibility of car fires. Of course they would not put that statement in writing.
I continued on the drive to Boston, which took longer than normal because of the need to (1) make more frequent charging stops and (2) wait longer for the car to charge (it now takes about 1 hr to go from about 40 miles to about 85% and over 2 hrs to charger to 95% ( the last few percentage takes so long I haven’t sat at a supercharger to see how long it would be).
In Boston, the car “died”, giving several error messages including that the battery voltage is too low (it’s words, not mine), while the indicated battery range was 150 miles. Tesla sent a tow truck for the car. When the tow truck arrived the car worked. I still had them tow the car to check it out.
Several days later I got the car back and was told they couldn’t reproduce the problem, even though they saw the error messages in their system. I made it back to Florida (taking a day longer than usual due to the longer charging time and more frequent charging stops) and have a third appointment next week for Tesla to check the battery. In the meantime, the Florida service center has escalated the battery issue.
I have the P85 and a model 3. Other family members have Tesla cars. I also own stock in the company. I was thinking of upgrading to a newer S for the increased range. After experiencing Tesla removing battery capacity without telling me and getting my approval, I have given up on the idea.
Btw, I was contacted by the attorney that filed the class action lawsuit to become a member in the lawsuit. I have not spoken to him yet.
Where there is smoke there is fire.Oh wow. The Service Center verbally told you that the reduced range is to “reduce the possibility of car fires”.
Wow. That’s exactly as Jason believes. Me too.
