FSD v14.2 Lite goes wide release: legacy Tesla owner reviews, rollout status

Tesla (TSLA) has pushed FSD v14.2 Lite to a wide range of legacy Tesla cars with Hardware 3 (HW3) computers. The automaker released this update widely after a few days of initial testing and data analysis.

The FSD v14.2 Lite is the third installment of FSD v14 for older HW3 Tesla cars that can’t process the more robust versions of Full Self-Driving built for Teslas with Hardware 4 (HW4) or later-generation inference computers.

Before Tesla started releasing the FSD v14 Lite updates, HW3 car owners were stuck on subversions of FSD v12 for more than a year.

The firmware version of FSD v14.2 Lite is 2026.27.6, which is the same as FSD v14.3.9 for HW4 cars.

Tesla hasn’t added any new information or noted changes in the FSD v14.2 Lite release notes from the previous versions. You can read the complete FSD v14 Lite Official Release Notes with new feature details here.

FSD v14.2 Lite Reviews

What’s more exciting for an owner whose 5-, 7-, or even 8-year-old car is getting better with new over-the-air (OTA) software updates?

With the FSD Lite updates, Tesla has found a way to keep older cars in the loop on new developments and features.

For example, the following video is of a Tesla Model 3 purchased 7 years ago. After getting the FSD v14.2 Lite update, it can now navigate a covered parking space on its own. It even swerves to avoid a car illegally changing lanes from the left.
