I took delivery of my Plaid 2 charges ago, and both nights it charged to 97 & 98%, and it's set to 90.
I've had model S since 2014, and have 2 HPWC's, and I've seen this before on our other cars, but usually it's a 1 off thing.
Today I did a reboot.
Anyone else experiencing this with plaid?
Tonight I will set the limit to 80 and I hate having the battery sit at high SOC for long periods.

No big deal. 98% is just 4 quick 1/4 mile runs to get it back down to 90%. Should take you about 38 - 39 seconds. :)

...so this morning it charged from 25% to 88% after being set to charge to 80%. So it's going 8% over, Since I took delivery. I will just leave it at 80 and chalk it up to a future software update.

@omarsultan I vaguely remember you mentioning that the battery estimations are off. In my case I have 19's and the estimator is coming in at 355 when I plot out.
Was that resolved as well? The car is on 2021.12.4.9

Yeah, its seems like the BMS needs some time to calibrate--its settled down after a couple of weeks. The overcharging showed up with FW .3 -- in my case, I was setting to 90% and car was charging to 92%. The car has since settled down again (currently running .4), so maybe a FW thing or some BMS housekeeping along there way. 🤷‍♂️
