Of course. The problem is however circular. You trust the article on the Volt because you trust GM. Why do you trust GM?
Logically -- never mind external factors like "everybody knows who GM is -- logically the Volt owner's manual is no different than the Mills Computer Company's manual for its perpetual motion machine.

Mills Computer Company could announce a perpetual motion machine and publish documentation for it. That would be a primary source, yet for an obviously fictitious thing. You would have trouble, however, finding a press article or a SHARE presentation that confirmed our product's existence.
