Notes
NHTSA
One-line summary: The US National Highway Traffic Safety Administration — the federal regulator with recall authority over vehicle safety, and the primary escalation risk to tesla-fsd.
What it is
NHTSA investigates defects, issues recalls, and sets federal motor vehicle safety standards. In the autonomous-driving space it has become the most active federal actor on ADAS and "self-driving" systems, running multiple concurrent investigations into tesla-fsd.
Why it matters to autonomous-driving
NHTSA's Engineering Analyses historically conclude in 18 months and often precede either closure or a mandatory recall. Outcomes here materially shape which autonomous systems ship and in what form.
Key facts
- Active Tesla FSD investigations (as of April 2026): three concurrent 2026-04-20-autoresearch-tesla-fsd.
- EA26002 (Engineering Analysis): Escalated in March 2026 from preliminary evaluation PE24031 (opened October 2024). Scope: ~3.2 million vehicles; nine crashes in reduced-visibility conditions with one fatality and one injury; six additional incidents under examination 2026-04-20-autoresearch-tesla-fsd.
- Core technical concern (EA26002): FSD "did not detect common roadway conditions that impaired camera visibility and/or provide alerts … until immediately before the crash occurred" 2026-04-20-autoresearch-tesla-fsd.
- PE25012 (separate probe): Traffic-violation incidents (running red lights, crossing into opposing lanes) — 58 initially, up to ~80 by December 2025. Tesla requested multiple extensions, citing 8,313 records requiring manual review at ~300/day 2026-04-20-autoresearch-tesla-fsd.
- Reporting standard: NHTSA uses a 30-second crash-attribution window; Tesla uses 5 seconds in its public safety report 2026-04-20-autoresearch-tesla-fsd.
