FSD v14.3.1 (2026.2.9.7): Tesla owners report some regressions, rollout status, and Release Notes

Tesla has begun rolling out FSD v14.3.1 (firmware 2026.2.9.7) to more users in the US and Canada as a minor update to the earlier v14.3 release. Some Tesla owners are reporting regressions, meaning the update may introduce new issues or performance declines compared to the previous version. For owners and enthusiasts, this signals that while the rollout is expanding, the update is not without bugs, and they should monitor feedback before installing.
