Join the club. Full charge here is 97% with average brick voltage of 4.17. no more 100% charging for us.

Look for the brick voltages with scan my Tesla. You will see that they never reach 4.2vI have a obdlink MX+ and the cable to hook up to my car. If anyone could tell me what to look for in scan my tesla I could check my battery balance / voltage ect... but Im not sure what to look for.
Thanks for taking the time to put 400 posts into a condensed explanation. Kinda shitty that this happened to our cars. I understand the decision behind it (save battery longevity, reduce fire risk etc...) but it's hardly an adequate solution when you think about modifying the cars we purchased with certain expectations in mind. Its like buying a F150 with a 30 gallon tank and Ford snuck into your driveway and replaced it with a 25 gallon tank, without your permission. Feels real shitty.It' not balancing. It is a thing that started to happen to a lot of cars. It is part of the software being extra careful about having the car being at near 100%. Not going to repeat the whole thing layd out in 400 pages in that other discussion. What's basically happening is that Tesla noticed having the battery at 100% is more harmful than initially thought and especially to older batteries. There are many measures Tesla implemented that reduces the battery charge level and rate and so on depending on how old a battery is and how much use it has seen. The car stopping to charge before it reaches 100% is one of those tings. I have seen this issue on my car as well. For some reason it is only happening on AC chargers. At superchargers it will always charge to 100%.
Tesla is telling everyone that comes to service that 'balancing' was the issue and recommend this nonsense routine where you have to discharge to low SoC and then charge to 90% or higher again for weeks or months. First of all, it is not balancing. I have monitored my pack via CAN bus for more than 3 years. Balancing has not changed ever. Regardless of my driving or charging pattern. It is as good as it was 3 years ago. It is very good in fact. Yet Tesla told me to do this rebalancing routine for 3-6 months. It's just their way to say, go away.
I find it pretty telling that Tesla is refusing to show any owner the results of their remote diagnostics. What car repair shop refuses to show a client their findings? When I questioned Tesla about it they instantly waived the fee for the diagnostics on my car.

I would really love to just have a definitive answer on some things. One of the major reasons I purchased my Model S was because superchargers went up a mile from my house. My research showed, at the time, that frequent supercharging had little detrimental effect on the batter (degredation / health). So I made my purchase with the mindset that 90% of my charging would be done at the superchargers around the corner from my home. I know this doesnt sound very convenient to most, but I'm a numbers guy, and my financial planning (reasoning) came down to savings on gas AND electricity (although cheaper than gas). Now, supercharging is crippled and it could be killing my battery? I just don't know how to handle this battery anymore for the sake of longevity.It is a messed up situation. What it comes down to is that Tesla has put themselves in a cul-de-sac. They pushed the battery packs to the limit well knowing what they did. It was a calculated decision. They knew a few would push the car every day and those batteries would fail and be replaced. The vast majority would drive like a normal person and not stress the battery too much making it passed the 8 year warranty. Having the best range, quickest acceleration and fastest charge rate would give them a significant advantage over the competition. Quietly they reduced the charge rate of the car little by little over the years hoping people wouldn't notice. I think Tesla got caught off guard when the fires happened and upon further investigation they realized the batteries are aging faster than expected and they released all these software limitations on the fleet. Some just to specific cars, others affecting every car.
We laugh at the other EV makers and how conservative their range, performance and charge rates are. No one is pushing it that far because they all have extensive experience in warranty claims when millions of cars are sold. Especially with a large, expensive battery, the potential cost could get the company is serious trouble.
The frustrating part is Tesla's lack of communication, all along. I wish they would have warned us of the effects of Supercharging and 100% charge clearly. But they didn't want to. In fact they never talked about anything that would even remotely hint that you should be easy on the battery. That would have cast a shadow on Tesla's superiority in the EV world and hurt sales.
I have the same issue. It’s Tesla causing it. On some older cars, Tesla capped the charging rates. Theirs a class action suit on this. If I’m correct, you’re rated mile we’re reduced as well and Tesla’s response is to say it’s normal degradation.I’ve tried to max charge my car three times every single time it stops at 98% and says charge complete. When I try to get it going again it won’t. Has anyone else had this problem?

Trust me. I’m NOT just a Tesla fanboy (girl) that thinks they can do no wrong. They can. They have. They will. But I also don’t think that these packs fail in a super high percentage.
Havent tried yet, doing a few more deep cycles. But I got battery preheat and regen back with that update. So hoping my battery is also fixed (or bms)So after 2020.4.1 I was able to get to 100% this morning. Anyone else?
home charging or SuperchargingSo after 2020.4.1 I was able to get to 100% this morning. Anyone else?
Deep charge/discharge a couple times. Like 20-90% or so. Fixed.My 2018 Model 3 Performance is having the same issue. The app slider doesn’t let me select more than 98% charge. Any idea how to solve that? The car has 16k miles and the battery usually is set at max 50% charge since March.
