@Rocky_H. As it happens, Teslas currently in production have three 16A AC to DC converters. When my M3 gets plugged into my (Gen 2) Wall Connector, you can see the current going up to 16A; a pause, a slight drop in current, then it ramps up to 32A; a pause, a drop in current, then it ramps all the way up to 48A.
There are SR (Standard Range) Teslas with smaller batteries and AC to DC converters sized to match; Those go up to 32A, max, and only have two of those 16A modules.
In your case, with a Model Y, it kind of looks like the third module isn't kicking in. There have been multiple reports on the Tesla forums about failure of some hardware that causes one or two of those modules to not kick in, or kick off-line. Warranty work will fix the issue, if that's the issue. But, before calling Tesla on the app for repair, it's sane to check if the current isn't limited on the charging screen, in which case the problem would be user error
.
So, check for user error, and if that's clean, put up a charging problem on the app. If that's the case, Tesla will make it good.
