You're right, that would be very newsworthy! Of course, it's not true, which I think rather supports my point about the headline.
(If you read the article, the number of repairs needed is actually only ~1k, because only 2% of the 53k cars actually has a faulty gear that needs replacement. The recall is for 53k cars because they don't know which 2% has the issue, so the headline is technically true, but there's a big difference between "Tesla shipped 53k defective cars" and "Tesla shipped 1k defective cars". The former is much more newsworthy! But also false.)
I'm pretty used to the Tesla/Elon sycophants on HN (and Reddit and Twitter for that matter) but fabricating a headline to knock down is pretty brazen.
Parent's "quote" was just a paraphrase. Calling it a fabrication is a bit much, don't you think?
Anyway, it deserves a knock down, IMO, because the first instinct when reading it is that there is an issue with the breaks that people most commonly use. Using the parking break isn't nearly as common or frequent as the regular breaks. Simply adding "parking" into the headline would have made it far less sensational and far more accurate.
Core issue: "A small gear may be defective in some cars; you should come into the service center and get it checked. If it breaks, you may be unable to disengage the parking brake."
Headline: "Massive recall over brake issue!"
It's not technically wrong. But it misleads more than it informs.
