Feds find more complaints of Tesla’s FSD running red lights and crossing lanes

The National Highway Traffic Safety Administration (NHTSA) has identified at least 80 instances where Tesla’s Full Self-Driving (FSD) software allegedly violated traffic rules by running red lights or crossing into incorrect lanes. This marks an increase from around 50 violations reported when the agency opened its investigation in October 2025. The complaints include 62 from Tesla drivers, 14 submitted by Tesla itself, and four from media reports. NHTSA’s Office of Defects Investigation (ODI) is examining whether Tesla’s software can reliably detect and respond to traffic signals, signs, and lane markings, and whether it provides adequate warnings to drivers. Tesla’s responses to these inquiries are due by January 19, 2026. The investigation also seeks detailed data from Tesla, including the number of vehicles equipped with FSD, frequency of software engagement, and any related customer complaints, including those from fleet operators or legal proceedings. This probe follows a previous NHTSA investigation started in October
