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.)
- delecti 7y agoThe problems I've had to repair on the cars I've owned have mostly been things that don't exist on an electric car. If you weight repairs by cost, then it skews even further. And probably most of the ones that would still apply to an electric are maintenance tasks (replacing bulbs, brakes, tires). All of the non-drive bits of the car are still there, but in my experience those just don't fail as often, and they can generally be tolerated a bit before fixing it. Drive bits breaking in an ICE car tend to make the car undrivable.
- ptaipale 7y agoInteresting. From what I have heard, Toyota Prius, which as a traditional hybrid has both an internal combustion engine with its drivetrain and electrical drivetrain and batteries, does not suffer from much more drivetrain defects than pure electric (or pure ICE) cars. Toyota is generally known for quality build and good aftermarket care. Prius gets more rejects in the annual inspection in my country (Finland) than e.g. Avensis or Corolla which are powered by gasoline or diesel ICE, but the primary defect sources are - brakes - suspension faults - front wheel assembly defects (typically ball joints and tie rod ends) - tyres (which are too worn) Why are suspension faults are more common in Prius than in other Toyotas? I would guess it is because of the weight of the drivetrains, engines and batteries.
