This is exactly why I’m so uninterested in driving en EV. I usually word it as “I don’t want to drive a computer”, but the reality is that I don’t want to be on the wrong end of the power imbalance that comes from this amount of complexity.

PHEV in the title is plug-in hybrid electric vehicle. Different from a pure EV.

Does that make a difference in this regard? If so, how, and is it an unavoidable penalty for PHEVs? I can see PHEVs having a complexity penalty from having an IC engine over and above the EV components, but that does not seem to be the source of the problems here.

I would say so for this particular failure.

The issue in this case has everything to do with the electronics design and close to nothing to do with propulsion.

The issue described is happening because German car makers love to put generic parts inside proprietary modules that cannot be repaired, and require extensive OEM tooling to replace. This kind of dumb shit happens on ICE cars and EVs that follow this design paradigm.

As described int the article the actual failed piece is ~$50 if you can replace just that pyrofuse. BMW doesn’t allow tha though. So you have to replace the entire module
