Tesla's 'Full Self-Driving' Under Increased NHTSA Scrutiny for Low-Visibility Issues

• Investigation involves 3.2 million Tesla vehicles including Model S, X, 3, Y, and Cybertruck equipped with FSD systems
• NHTSA found that Tesla's camera-based system may fail to detect or warn drivers about degraded visibility conditions until immediately before crashes occur
• Probe was elevated after reviewing crashes where FSD was in use within 30 seconds of impact, including one fatal pedestrian incident

SUMMARY: Tesla Faces Escalated NHTSA Investigation Over Full Self-Driving Safety Concerns

The National Highway Traffic Safety Administration (NHTSA) has escalated its investigation into Tesla's Full Self-Driving (FSD) (Supervised) system, upgrading the probe to an "engineering analysis" phase. The investigation centers on potential safety defects affecting FSD performance in reduced visibility conditions, including fog, glaring sun, and other environmental obscurants.

Key Details:

• Scope: The probe covers 3.2 million Tesla vehicles, including Model S, X, 3, Y, and Cybertruck models equipped with FSD capability
• Core Issue: Tesla's FSD system allegedly fails to detect and adequately warn drivers under degraded visibility conditions where camera performance deteriorates
• Investigation Findings: NHTSA reviewed multiple crashes where FSD was active within 30 seconds of collision, noting the system failed to detect "common roadway conditions that impaired camera visibility" until immediately before impact
• Fatal Incident: The probe includes at least one fatality where a Tesla driver using FSD struck and killed a pedestrian

Market Implications:

The escalation from initial investigation to engineering analysis represents a more serious regulatory concern that could result in mandatory recalls or design modifications. This development adds to Tesla's regulatory challenges and could impact investor confidence, particularly as the company has marketed FSD as a premium feature and future revenue driver. The investigation's broad scope covering 3.2 million vehicles suggests potential financial and reputational risks.

Tesla has not provided immediate comment on the escalated investigation. The engineering analysis phase typically precedes potential recall decisions or enforcement actions.
