Tesla FSD Fails Again at Railroad Crossing, Nearly Causes Train Collision

Recently, a vehicle equipped with Tesla's Full Self-Driving (FSD) software version v14.3.7 failed to stop in time at a railroad crossing, narrowly avoiding a collision with an oncoming train. Owner LeiXing shared dashcam footage on social media showing the car approaching the crossing at approximately 15 km/h. Despite clearly visible flashing warning lights and audible train horns, the system only briefly slowed down before attempting to cross the tracks. The driver ultimately had to intervene manually to brake and prevent an accident. FSD v14.3.7 is the latest version Tesla has rolled out to vehicles with AI4 hardware, touted as improving recognition of rare and unusual objects. However, in this incident, the system failed to detect both the railroad crossing gate and the approaching train. According to public reports, in March 2024, a Tesla in California crashed through a railroad crossing barrier; in May, another Tesla in Texas struck and broke through a crossing gate just seconds before a train arrived; and in a separate incident in Pennsylvania in 2025, a Tesla drove onto the tracks and was struck by a train. NBC News reports that over 40 cases of Tesla vehicles failing at railroad crossings have been documented to date. The U.S. National Highway Traffic Safety Administration (NHTSA) has already launched an investigation into the FSD system, focusing on issues such as running red lights and driving into oncoming traffic lanes. The probe covers approximately 2.9 million Tesla vehicles. Senators Ed Markey and Richard Blumenthal have sent a letter to NHTSA urging a dedicated investigation into FSD’s failures specifically at railroad crossings.
