I briefly owned a Chevy Volt with the worst infotainment UX imaginable. I found a quote from a Chevy spokesperson describing it as an "Apple-like experience," presumably because the graphic designer on Fiverr found the Gradient tool in their pirated copy of Illustrator CS6.
True, but even that's just at the surface level. When you dig into the architecture / planning / business strategy that happens in Detroit, it's even worse than what the UI suggests.
"Creative destruction" is coming for them real soon.
That is a 10-year old UI based on their even older designs from their ICE vehicles. The newer UI for the Ultium is much more modern. Not as severely styled as some other companies not not as overdone as that old UI.
