As you say, it is not a hybrid (which has most of the parts of both ICE and EV and is *more* complex). Of course there are advantages to a hybrid that address many of peoples concerns re EV's.
The big things that disappear from EV's: exhaust system (these are constantly deteriorating for me here in the salt belt and a regular pita), conventional oil lubrication and cooling systems (though depending on the design, some EV's have some sort of cooling systems, and whatever they need for HVAC), including oil pumps, water pumps, radiators - all common repair items. No fuel systems or tanks. Some EV's do not even need transmissions. Obviously there still are suspension components and they will still be the same amount of work to repair.
There was a company making pancake wheel motors a few years back. What was kind of cool there was that they were basically able to also eliminate the conventional hydraulic braking system. That's another significant maintenance component of cars (eg brake line leaks plague c900 floors!). Obviously the reliability and safety of the integrated braking would need to be properly evaluated, but the simplicity is intriguing.
Added complexities of EV's are high power delivery systems (eg inverters, etc), charging setup etc.
All cars are loaded with electronics already, whether for dash, entertainment, computer control of braking, throttle, engine management... and the kinds of things that are additional in an EV are no more complex or fundamentally that different even, aside from the high power parts. Generally electric motors are very reliable components. Obviously this can be implementation dependent, however.
From what I've heard from owners, maintenance costs are definitely lower. I've also heard few if any complaints re batteries from Prius owners, though they are less reliant on battery capability where they are hybrids. Prii have been on the roads now for quite some time and there are many of them, so we would probably hear if they were not working out. I have heard that taxi drivers really like the early version prius because it is quite overbuilt and very reliable. I'm not interested in them because they are slow and boring, but they seem to work well for their purpose!
