The latest development with the late 2019-2022 Bolts that were built with the US-built battery but before the recall production-stop, is that rather than replacing the batteries in all of them, they were going to install software to limit charge to 80% while it watched for certain telltale signs that the battery needed replacement, and only replace it if that software indicated a fault, and this was to be active for 10,000 km at which point it would revert to being able to charge to 100%. But then it was discovered that this fault-detection software was false-tripping, and there was another software revision to fix that (still leaving the 80% charge limit in place for 10,000 km).
Vehicles built after (I think) early calendar year 2022 (includes mine) were built post-recall and aren't affected by all this. Very few 2022s (only a very small number built very early), and no 2023s, will be affected.
So, step 1, check VIN with dealer. Step 1A have the dealer confirm that it has the correct software in place for what battery is in the car, and whether that is affected by the 80% charging limit.
Step 2, turn car on, on center screen press the green leaf down near the bottom, select the "Charging" tab, "Options", "Charging limit" brings up a bar graph (there's two different ones, "Home" and "Away", check both). The white line on the scale is what the charging limit is set to. If it isn't already at 100%, drag it to 100% and see whether it accepts it or not.
The really early ones don't let you set any charging limit that you want, it either charges to 100% by default or there's a "Hilltop Reserve" that limits it to (I think) 88%, but this was changed after the first couple of years. But those should have all had the battery replaced as opposed to the software shenanigans. If you find an early one that hasn't had the battery changed (only for owners who were living under a rock, or didn't care), it remains eligible, and the dealer should be able to get it changed for free.
