I actually think these are all engineering problems. I mean they literally made light bulbs break when it's easy to make them last decades.

They certainly do fail, many teslas are on their third drive unit now. And batteries do also fail. Not sure why you would say otherwise.

Define "many" and give a citation.
Tesla warranty for the drive unit is 8 years/120,000 miles. I doubt they'd set it that high if the expectation was that these drive units are going to fail all over the place.
Compare that to both ford and toyota which have a 5 years/60,000 miles powertrain warranty
> And batteries do also fail
They can due to manufacturing faults. However, both batteries and engines follow more of a washtub curve.
> Not sure why you would say otherwise.
You are overstating the failures of both.

The citation is right over there, next to the citation for EV's having fewer parts and being more reliable. The correct statement would be that EV's have fewer moving parts which is correct but irrelevant because with EV's there are many thousands of non-moving parts that can also brick the vehicle.
Almost never. EV motors and their gears don't have the problem of injected pollutants in the oil. This is why most are expected to last a million miles or more.
The lack of a transmission also eliminates a major point of failure (gear shifting)
> But batteries have thousands of parts and electrical connections.
Those aren't mechanical parts, that's the big difference. When people talk about EVs having fewer parts, they are referring to the moving parts. The parts that most commonly fail in ICE.
