EV vs ICE Maintenance

The cluster debates the maintenance costs, reliability, and mechanical complexity of electric vehicles (EVs) compared to internal combustion engine (ICE) vehicles, with most comments arguing that EVs have fewer moving parts and lower long-term maintenance needs.

But you don’t really. You get a weak drive train as many moving parts as an ICE plus a non-trivial size battery that is expensive to replace. Your maintenance costs potential are as a bad as an ICE plus an EV. EVs are way more elegant solutions, simpler, better performance. Also, EVs are improving rapidly, charging speed and range keep getting better.

Is this true over the lifecycle of an ICE vs EV?

If anything EV seems easier than ICE

You are talking out of your posterior. EVs are far more reliable and have less maintenance than ICE vehicles.

On all those areas, an EV is better. Modern ICE vehicles are hugely complex because its they only way they can meet emissions targets. EV power trains are much simpler in comparison, and electronics are much more reliable. Batteries are not the issue that the naysayers say they are - lasting much longer than an ICE engine (which usually die around the 250k mile mark) , and at similar replacement cost at that point. And in the meantime you've saved hugely on servicing and maintenance costs -

Yep, fully EV for 99.99% of trips but functions exactly as an ICE car for edge cases is a no-brainer purchase. I don't really care about servicing the batteries more often because there's fewer of them and the ICE engine is likely to get 1/10th the miles of the car overall so it probably won't be the source of problems.

The simplicity of EVs is one of their big strengths! Compare all the cooling, transmission, lubrication and fuel systems of an ICE car to the simple Electric Motor of an EV. Vastly simpler. As an end user, I see it to, my EV has no scheduled maintenance, whereas the ICE wants me to take it to the dealer every 20k miles.

Ye ... my experience with old cars is that the ICE is not the main time or money sink.Thinks like drive axis, suspension parts, wheel bearings, brakes etc is common with EVs - and those fall apart.The timing and generator belt headache is replaced by two selfdriven motors/pumps on EVs for the oil or water cooling system and servo. Hardly less mentainance and more expensive parts.The main thing is that most EVs are new so most have not had their exposed systems beaten out of spec an

Modern ICE have been refined for over 100 years and have improved enormously. But there is just a lot more involved in making them move than electric engines.That's not to say EVs aren't complex or hard to build. There are a lot of parts inside the battery pack. But they aren't moving parts and they don't need the same kind of regular maintenance. Electric cars don't have oil to change and they almost never need brakes replaced because of regen. They don't have O

There are just as many moving parts in most evs as ice cars.
