I'm no expert on the subject, but unless something else happened at Tesla yesterday, this was indeed what caused the dip. About a year ago a youtube video popped up of a Tesla caught fire after it hit a metal object which pierced the battery pack. The stocks immediately plummeted, even though car fires are a common thing. Like the article states, it is likely the negative news story was fabricated to drive prices down, to gain profit for those selling short on tesla stocks.
