The fact is that Volvo's reputation and prioritization of quality builds and stringent safety measures (I owe my life to a rental Volvo S90) are not shared by its Chinese parent company. When that philosophy trickles top-down, Volvo is affected.

In Apple's case, even as a iOS hater (yet a user), I would still say that Apple prioritizes product quality standards at a very high level. That culture trickles down as imposed requirements from Apple to its suppliers.
