Usually, manufacture or design defects are hidden to the end customer. The car was built to spec, but the spec was wrong; or the part supplier supplied a non-obvious faulty part. It’s not like an obvious safety-related part is entirely missing.
This is a very different kind of problem than leaving out a brake pad. It’d be like delivering a vehicle without a seat belt or airbag.
At any rate, nobody is saying that other car manufacturers don’t screw up. They just typically screw up in non-obvious ways today instead of patently simple ones.
Finally, “what about this other company/person”
arguments aren’t HN-caliber. They’re not logically sound, and are best left at the door.
