NHTSA upgrades probe into Tesla Full Self-Driving over low-visibility crashes
Preliminary Why: Publisher not yet named · subject to change
Developing: a major or severe case captured in the last 72 hours. Later changes are logged on the corrections page.
Status: action reported, no fix
No source states: loss or records, agent tool, could do, deployer.
Severity severe: Safety-of-life test met: the expanded scope includes one fatality and one injury
NHTSA has upgraded its investigation into Tesla’s Full Self-Driving system to an Engineering Analysis covering an estimated 3,203,754 vehicles. The agency found that the system’s degradation detection fails to warn drivers when cameras are blinded by conditions such as sun glare and fog. The preliminary evaluation began in October 2024 after four crashes in reduced visibility, and the scope has since expanded to nine incidents with one fatality and one injury. NHTSA also believes Tesla’s data limitations could have led to under-reporting of crashes. Tesla began developing an update to the degradation detection system in June 2024, but NHTSA does not know when that update was deployed.
