U.S. Safety Agency Intensifies Scrutiny of Tesla’s Driver‑Assistance System After Nine Crashes, One Fatal

The U.S. safety agency has stepped up its examination of Tesla’s driver‑assistance feature after nine crashes—one fatal—linked to the system.

  • Scope of Review
    The review covers about 3.2 million Teslas sold in America, representing almost all of the company’s cars on U.S. roads.

  • Potential Consequences
    If a defect is found, regulators could order a recall or other action.

  • Focus of Investigation
    The focus is on the “degradation detection” tool that should spot when road visibility drops and alert drivers.

  • Reported Issues
    Reports show the system sometimes missed glare or other obstacles, both before and after software updates.

  • Tesla’s Response
    Tesla’s own analysis suggests that a recent update might have caused three of the nine incidents, according to the regulator.

  • Safety Concerns
    In several crashes, the system failed to warn drivers until it was too late. The agency also found other accidents in similar conditions where the warning came too late or not at all.

  • Broader Implications
    These findings raise questions about Tesla’s plans for fully autonomous cars and robotaxis, which rely on this technology.
