Why Are Japanese Engines So Reliable? by ibinaboonline: 5:53pm On Oct 12, 2023
True story from a former Toyota employee:

Many years ago I worked at a Toyota factory in the USA. One day we had some visitors from GM taking the factory tour and the visitor’s center was hospitable and had them meet some of the engineers and technical people (I was in IT and honestly had the best personality to deal with visitors so was invited along).

The GM people asked us to see our rework yard. I had no idea where or what that was so I asked my colleagues what it is and where it is. They were as confused as me.

When asked, the GM folks told us it’s the lot where they keep cars that come off the assembly line with defects so that they can be patched up and sold.

So we took them to the small warehouse area where we keep the dozen or so cars that come off the line with a minor issue that we can fix and make it as good as every other car. More often than not it was an issue with the stitching on the seat or a steering wheel or something like that, and we would just replace the part that was imperfect.

GM guy: “Where’s the rest of it?”

Me: “This is it. What do you do?”

GM guy explained they had a large lot for cars that come off the line with faulty body work or engines or transmissions, and they’re patched up so they can be sold. Then he said “what do you do with your defective cars?”

We explained that it rarely happens, and when it does we study it, figure out what went wrong, fix the issue so it won’t happen again, and then either keep the car for further study and training purposes or crush it. Nothing that comes off the line with a serious defect leaves the factory.

And that’s why Japanese engines (and vehicles) are known for reliability. Yes, tolerances are tight and yes, Japanese companies avoid untested technology. But that’s secondary.

The main reason is that anything defective that gets produced is studied, not sold, and then improvements are made so it won’t happen again.

The Japanese do make bad cars sometimes. They just don’t sell them.

Not everyone can say that.

Basic simple engine technology bro
Nothing more nothing less
Other car manufacturer prefer sensors and complex electrical part which of cos fail most time tongue

I remember that Toyota TV ad back in the day; "Good thinking, good product."

And this reliability and build quality matters.

It matters a lot to the average car buyer.

Most people don't need big, hulking, thirsty, performance oriented engines. Or cars that steer as if they are trains on a railtrack. Or unnecessarily complicated technology that adds more costs with few benefits. The Japanese understand this.

Japanese car makers focus more on selling a product and less on selling a brand. The product is what matters.

The world will be a poorer place when the likes of Toyota become slaves to branding, image, prestige and all the other intangibles that German car makers deceive their customers with.
