After ~20-30 years, rubber gaskets and seals and cable insulation start failing. Plastic becomes brittle, especially if exposed to the sun. How do they solve this problem?
I would think an electric vehicle would have quite a lot fewer things like gaskets and other seals since gas isn't involved. Other than the normal wear and tear items like brakes, shocks, rotors, etc, battery repair would be the major thing I'd expect to need work. I imagine many mechanics aren't trained to handle these, so they end up just replacing the whole unit. Obviously this is wasteful though but could be easily solved via training.
Pretty much this, diagnosing and fixing an electric motor is about as difficult as an alternator. Check signal, if good remove unit and swap (core gets remanufactured). With drive by wire and steer by wire and all that most things are equally modular. Gas pedal/throttle unit is pretty much a rheostat with a spring-loaded pedal, steering rack actuators, etc
Then you got ICE which becomes a ship of theseus. If you put enough hours on a combustion engine you go from the simple stuff like hoses and timing belts to having to replace piston rings, bearings, or even the cylinder heads if they get so worn out that they leak and fail compression tests
Spoken like someone that doesn’t work on cars.
Cars used to be much more modular. Newer models of car - much like newer models of cell phone - are deliberately engineered to be difficult to disassemble and fix, in order to compel people to replace the whole vehicle on a tighter time frame.
Yep. Like Tesla with its large castings. Makes the cars unrepairable. EV’s are the worst at this too.
It was a big reason for the surge in popularity of Japanese cars, during the 80s/90s. Honda Civics were famously very easy to mod, leading to the trend of "Rice Rocket" cheap urban street racing cars. That's fallen off substantially in the last ten years, thanks to Japanese companies becoming infested with Wall Street / McKinley Consultant profit-chasers. Toyota and Hyundai might as well be run by the CEO of GM, the way they build their vehicles.
But a lot of the new Indian and Chinese vehicles are adhering to more traditional modular manufacturing style. They're also having a really hard time getting their vehicles into Western dominated car-markets, for some curious reason.
Agreed 100 percent. I’ve never touched anything Chinese so I’m clueless there, but from what I’ve seen they are quite far ahead in the EV front. It’s a shame we don’t get the good stuff that Toyota still makes in Australia
