Model S HW3 owner reports restricted speed profiles on FSD v14.3 Lite

📍 Reddit Tesla FSD October 17, 2026 at 04:34 PM

Unconfirmed: an owner of a Model S with HW3 hardware claims on Reddit that, after a week with FSD v14.3 Lite, the speed profiles are heavily restricted compared to v12. According to the post, with v12 they used Standard mode for nearly all their trips, positioned between Mad-Max and Chill, and could raise the speed with the Max-Speed setting by voice command. They describe the version as barely usable and list several problems, although the available text cuts off before detailing the rest. It is one user's experience, not a Tesla statement.

HW3 user claims v14.3 Lite speed profiles are completely restricted.
On v12 they used Standard mode and voice-activated Max-Speed to adjust speed.

🔎 Why it matters: There is no official confirmation from Tesla. The post claims that on v14.3 Lite in a HW3 Model S, the Standard, Mad-Max and Chill profiles offer lower speeds than on v12.

📈 Upside: Not applicable.

📉 Risk: If the restriction is real, HW3 users would lose on highways the configuration that, according to the author, let them relax on v12.
