Spot on.
These vehicles may have fewer parts, but their systems are more complex. My experience with EVs has highlighted issues primarily in two areas: infotainment and battery packs. Inside these battery packs, a complex network of modules communicates with both the primary ECU and each other, using both hard-wired and wireless connections. If any internal module that monitors voltage, heat, etc., fails to communicate, it can create a fault that may deny propulsion. This fault doesn't necessarily indicate a problem with the actual battery, but because it is responsible for thermal and HV safety, propulsion is denied if it can't communicate.
Infotainment systems, adaptive cruise control, collision avoidance, assisted parking, lane departure, 360-degree cameras, etc., are complex systems that communicate across multiple buses. Any glitch can create issues.
Many of these concerns can often be corrected with software updates. However, software itself is complex. New vehicles, both EVs and ICE, have firewalls that make programming a challenge. Often, a new module may fail during programming and require replacement. I could elaborate endlessly on this topic(but won't)
As with any new technology, there will be growing pains in the foreseeable future. In my opinion, both EVs and ICE vehicles have their place. It should be a personal choice, and the market should drive the technology, not immediate government policies.
My observations of late is that at the dealership level, EV inventory is higher than expected.
