Actually, a manufacturer that produces a product that contains a defect that the manufacturer either (a) knew, or (b) could have reasonably foreseen, would result in injury or fatality to users is in fact legally liable in the U.S., both criminally and civilly. This is the usual "negligence" standard in U.S. law. And the foregoing doesn't even assume that the manufacturer is liable under the so-called "strict liability" standard, where proof of knowledge or foreseeability are not even required to hold a manufacturer liable, only that the product was defective in some fashion. The strict liability standard applies most often in consumer products situations, where there are such a disparate states of knowledge and resources to correct a problem. I haven't spent the time to research wether the strict liability standard would apply to this issue (it's a question of each state's law), but my hunch is that it does. I note that California, Apple's home, is the most aggressive state in the U.S. in holding manufacturers to a strict liability standard.
An example of strict liability laws in action, analogous to that which may apply to the iPhone, is the typical Nav system consent/warning screen found in cars -- with its disclaimers and instructions that the system shouldn't be used while moving. It's the strict liability laws that make these screens advisable for manufacturers, however "dumb" they may seem.
In this case, it's not even challenging for a reasonably competent plaintiff's lawyer: Apple advertises that the iPhone 5 works with Bluetooth systems, including those in cars, yet it knows, to a certainty, that its phones do not work correctly, and will lead to fumbling around and distraction, by hundreds of thousands, if not millions, of car drivers. Inevitably, some of those car drivers will be involved in crashes, and Apple has done nothing to warn the public. That's a case I'd be tempted to take myself, if I was a litigator. (And yes, I am in fact a lawyer. But just a corporate lawyer. :-)). Heretofore, Apple has been making products -- computers, displays, peripherals, iPods that don't lend themselves to strict liability tort claims. Proof of defect or harm is difficult to prove. But as the iPhone becomes a central feature of how people use their 3,000 lb. hurtling missiles known as cars, that may be about to change . . . . Have you heard of the case of the woman who put a cup of over-heated McDonalds coffee between her legs at the drive-thru? It spilled; she sued and won. It may sound dumb, but there was evidence at trial that McDonald's made its coffee much hotter than the standard and knew about the possibility (hundreds of prior spill incidents reported to the company) and ignored it. A cautionary tale. Apple are you listening?
