Sometimes the CPSC did. Sometimes people had to resort to class actions.
It might be over a longer timeline (or at least, it took longer for Apple to acknowledge), but plenty of Apple products have sent people to the hospital, caused multiple fires and evacuations on airliners, and burnt down at least one house (even the Note hasn't done that). In the US alone:
US Recalls:
(That last recall involved as many batteries in the US, as Samsung Note 7 phones sold there.)
- 2001 - Apple recalls 570,000 adapters with fire hazard sold 1998-2000.
- 2004 - Apple recalls 28,000 laptop batteries with internal short.
- 2005 - Apple recalls 128,000 laptop batteries with internal short.
- 2006 - Apple recalls 1.1 million (1.8M worldwide) battery packs with fire hazard, injuries, property damage.
US Class Action Settlements:
Some people say, oh well these things happened over a longer time. That's almost worse. Remind me to steal ten bucks from you every week over ten years, because you don't think that counts the same as robbing you of the same amount over a month.
- 2008 - 2.3 million adapters w/fire hazard sold since 2001, took two years to settle.
- 2011 - 10 million power connectors, fire hazard since 2006, took two years to settle.
Samsung had a problem they couldn't figure out and stopped sales within weeks. Apple has had KNOWN problems for a decade at a time, and yet continued to sell the faulty products because it was cheaper to just pay for damages / replacements when victims came in, and let their PR team handle the fallout.
It doesn't matter how long it takes; the net effect on customers is the same in the end.
"Samsung had a problem they couldn't figure out and stopped sales within a week".
Seems to me a battery defect would be easy to determine, which makes me think it's not battery related but circuitry and/or battery defect. Needless to say, the fact that the airports have banned this device will do far more PR damage than settling in a class action lawsuit.
