Toyota weighs the cost of running individual wires (as a part of the harness) when building the Yaris. The margins are that hard at the low end. Adding any small tiny feature is hard due to the cost they are trying to hit.

Can't speak of the Yaris. My 2008 Prius with more than 100kmi runs flawless though. Surely (even accounting for survivor's bias) there would have been ways to cut costs. Methinks there are other motivations in play then just maximizing short term profit. I believe Toyota is in there for the long run. I'm not so sure that Tesla is.

I have had Prii since 2001 (back when it was a sedan). Had good experience with them until recently: 2011 prius with 110K miles had to have it's engine replaced. Decided to do that instead of getting another car because anecdata tells me this was an aberration.

Did you have the EGR valve and cooler cleaned? It's the most notable issue with the 2009-2015 that leads to head gasket issues. Although, some say it's fine until ~140k ish, it could happen earlier if oil changes weren't full synthetic, yearly, or less than 10k miles.

I drive Yaris with similar age, partly off-road. So far it is OK.

Toyota also sells 10 million vehicles a year, 10x what Tesla does. So yeah, any small change to their model lineup is under scrutiny because it gets multiplied 10 million times over.

Just like every other manufacturer. Small costs add up.

I guess. The luxury manufacturers, like Tesla, will just increase the price or add a subscription if they think they can market a feature. There's no money for that on the Yaris, the customers can't afford whatever it is.
