The National Highway Traffic Safety Administration (NHTSA) escalated its investigation into Tesla’s driver-assistance technology to an engineering analysis.
This advanced probe covers approximately 3.2 million Tesla vehicles sold in the United States. The move marks a critical step that could lead to a mandatory recall or further enforcement actions.
Regulators are evaluating the system’s degradation detection capabilities, specifically its response to poor visibility conditions like glare. The investigation examines whether the technology adequately warns drivers to retake control when performance is limited.
This intensified scrutiny follows a series of crashes, including one fatality, where the system failed to detect objects or environmental obstructions.
