Rumor: Tesla FSD v14 Lite for Model S and X Could Land Soon

An unconfirmed tip circulating on September 7, 2026, points to Tesla FSD Supervised v14 Lite for Hardware 3 Model S and Model X owners arriving soon, after IGN senior executive editor Ryan McCaffrey said Tesla AI lead Ashok Elluswamy told him at the Cybercab launch that the build was supposed to go out last week.

“For my @Tesla friends – and specifically Model S & X owners with HW3 who are waiting on FSD v14 Lite – I spoke to @aelluswamy at the Cybercab launch, & when I asked for an ETA on v14 Lite for S/X owners, he said, ‘Oh, I thought it was supposed to go out last week,’” McCaffrey wrote under his DMC_Ryan account. “So: soon!” The quote is McCaffrey’s recollection of a hallway-style conversation, not a Tesla blog post, software-release note, or official X statement from Tesla or Elluswamy’s own account.

Hardware 3 Model 3 and Model Y cars have already been on FSD Supervised v14.1 Lite in recent software lines, while Hardware 4 owners have been further ahead on the v14.x supervised stack. S and X owners still on HW3 have been the holdouts waiting for that Lite path, which is why Elluswamy’s reported “last week” comment landed as a near-term signal even though it is secondhand and unverified.

Tesla has not confirmed a ship date for S/X v14 Lite in a release, so treat the tip as rumor until cars actually pull the update or Tesla posts it. If the build does land in the next wave, it would close a long Hardware 3 gap on the older flagships and sit alongside other September FSD notes on the site, including Slovenia’s supervised approval as a sixth EU market.
