Outsourced parts are almost always the fault of the supplier - and I have experience with being a tier 2 or 3 supplier.
I sure there will be a design refresh before the Bolt comes back. Yeah, 55kw charging is not all that fast anymore. But to keep costs down to entry level affordability, like less than $35,000US, corners will need to be cut and cheap tailing edge tech will probably need to be used. Otherwise, all you've done is price the largest body of buyers, (lower middle class these days), right out of the market again.
And the EV market needs those low priced cars to achieve common market penetration. If they don't design and build to that affordability price points, then EVs will simply remain toys for the wealthy.
Pfffttt, Microsoft has been there, done this, and got a whole closet full of tee shirts for stuff like this many times over the years. In the end the users don't care and can't stop it. And they are, by in large, too lazy to change to something else to completely avoid it.
It hasn't ever affected the bottom line enough to matter to them. They will just pull this
bugfeature and wait for a better day. Or perhaps they will figure out a way to introduce it piecemeal to disguise it better.
