Fixing older cars with electronic problems is a nightmare everywhere. It is pretty much depending on getting the original spares which manufacturers might just stop providing at some time (and sometimes they get caught by some chip no longer being available).
On the other side, considering how many videos I see on youTube about people using batteries and electric motors from salvaged Teslas to build their own electric cars/conversions to electric, the technology seems to be quite hackable. In the end, an electric motor is easy to control and a battery is just a battery. So even a homegrown controller should be quite feasible, compared to managing ignition on a modern combustion engine.
I think the electric cars are rather going to trigger a wave of new small car companies emerging, as most of the required technology is quite commonplace. Which also should make maintenance and repair easier.
