That’s really only because most of our electricity is still produced through fossil fuels. As we move to renewables, that equation will shift rapidly toward net positive much before 5 years. And that’s not accounting for any technological advances (like sodium ion batteries) that happen in that time.
The 5 year figure is from a German study and is based on the German energy mix (which is indeed quite dirty). So yeah, that number will hopefully decrease. But even with that, the “up-front” emissions in EV production are a major issue that is tough to solve and rarely made transparent by EV manufacturers.
The main source is battery production and related to the mining and refinement of their raw materials (source, source). The exact emissions are hard to quantify. That being said, the lifetime emissions of battery EVs are still significantly lower, so it’s still a net benefit. For a bigger picture, you can check the references here and here.

What’s the upfront emission of EV production that makes it that much of a detriment compared to ICE production?

US energy is 40% renewable already. Solar is the fastest growing energy segment.
In my county, our electricity is 2/3 sourced from hydropower, so an EV has significant impact on emissions relative to an ICE car.
