Tesla FSD v14.3.7 fails to stop at active railroad crossing
Dashcam footage shows the latest Full Self-Driving build nearly driving into a passing train, marking at least the third such incident this year.
A Tesla running Full Self-Driving v14.3.7—Tesla's newest release—failed to stop at an active railroad crossing this week and nearly drove into a passing train, according to dashcam footage reviewed by Electrek. The driver was present during the incident and documented the near-collision.
The failure is particularly noteworthy because v14.3.7 is the current build available to users. According to Electrek's reporting, this marks at least the third documented case in 2026 where FSD has attempted to drive a Tesla through an active railroad crossing, suggesting a persistent gap in the system's ability to recognize and respond to train traffic warnings.
The incident underscores ongoing safety concerns with FSD's handling of infrastructure beyond standard road environments. Railroad crossings present a distinct challenge: they require the system to recognize visual and auditory warnings and come to a complete stop, even when no vehicle traffic is present. The repeated nature of these failures indicates the issue has not been resolved in successive software updates.
"A Tesla running the latest version of “Full Self-Driving” failed to stop at an active railroad crossing this week and nearly drove straight into a passing train, according to the driver and as evidenced in dashcam footage. The kicker: it was running FSD v14.3.7, the newest build Tesla has released — and it’s at least the third time this year that Electrek has documented FSD trying to drive a Tesla"— X · @leixing77 · via Electrek (Tesla)
