Electric cars are not that much simpler than ICE cars.
The drivetrain is simpler, but most parts of the car are similar and share the same potential weaknesses.
The body may rust, the doors have hinges and seals that may leak water, the windscreen may crack or its seams may leak, the brake discs will wear out (even if more slowly due to energy regeneration feature), the brake fluid pipes may corrode and leak, the suspension system wears out with every bump on the road and the springs may break or the shock absorbers become ineffective; the steering has ball joints and tie rod ends that will become loose and need to be replaced, there are heaters and A/C which have pumps and pipes and sensors and controlling electronics, the lights have to work and they have alignment motors, the windscreen has wipers and their controls, there are mirrors and their adjustment systems...
All these parts need to work, and getting the design right requires immense competence and experience from the manufacturer. All of these are required in an electric car just like in an ICE car.
I've been frugal about cars and over the past 10 years have bought cheap ones (here it means French cars, because their quality reputation is worse than their actual quality, and therefore they are cheap to run).
None of the cars have needed replacing or major repairs in the drivetrain or fuel system (apart from one Suzuki 20 years ago that had rust in the gas tank). I've always given them up because the things that wear out are in the other mechanical parts, mostly steering, suspension and brakes. None of the cars I've had have been beyond repair, but the cost of new parts and work to make them roadworthy exceed the price of the car (I don't want to do too much of that work myself.)
