It's been a lot more than that.
First they claimed that Tesla didn't use yellow caution tape, because Elon hated yellow (30 seconds searching on Google Imaged can debunk this), nor beeping forklifts because Elon hates the sound (a couple minutes searching on YouTube can debunk this).
When called out on this, Reveal apologized, issued a formal retraction, and haha I'm just kidding, they went straight into their next hit piece, alleging that Fremont is a safety hazard hellhole and is hiding injuries off the books. This triggered a Cal-OSHA investigation. The only thing the investigation found wrong was a single cord someone might trip over, and was fixed immediately.
Next Reveal came out with two sob stories - a worker legt permanently disabled due to fires started by welding galvanized steel (metal fume fever), and another who got an electric shock so powerful that it sent him flying through the air across the room. Except that metal fume fever is a zinc overdose causing flu-like symptoms and only lasts until your body metabolizes the zinc (a couple days to a week), and shocks launching people flying through the air like Superman only happens in cartoons.
On and on and on. There was a great article last year (Detroit Free Press I think) which noted how, despite their denials, Reveal's hit pieces precisely tracked UAW, down to quouting the same "experts" and focusing complaints on the same targets at Tesla (for example, a particular brand of adhesive) at the exact same time.
