Tesla FSD NHTSA Investigation 2026: Five-Week Extension Granted for Massive Data Request

Tesla just bought five more weeks to explain why its cars are ignoring red lights. The National Highway Traffic Safety Administration (NHTSA) granted the EV giant an extension on a massive data request following more than 60 complaints regarding its Full Self-Driving (FSD) software.

Deep Dive into the Tesla FSD NHTSA Investigation

This isn't just a routine check. The agency's Office of Defects Investigation (ODI) is demanding an exhaustive list of every Tesla produced, sold, or leased in the U.S. According to reports, the request includes specific FSD versions, cumulative usage data, and a full catalog of customer lawsuits and incident reports related to traffic law violations.

For every crash, Tesla must provide a detailed summary including 'causal and contributing factors.' The regulators aren't just looking at the hardware; they're questioning the very logic of the software. Tesla must explain its 'theory of operation' for how the system perceives traffic lights and stop signs.

What Tesla Must Prove by the New Deadline

The five-week extension gives Tesla more time to compile internal simulations and hardware modification logs. The goal is to determine if the FSD system has a fundamental defect that leads to ignoring critical traffic signals, a scenario that has already caused dozens of reported near-misses and collisions.
