Tesla Faces Escalated Safety Probe Over ‘Full-Self Driving’

US auto safety regulators escalated an investigation of Tesla Inc.’s partially automated driving system marketed as “Full-Self Driving,” citing additional crashes pointing to potential flaws in the technology’s ability to handle driving conditions with reduced visibility.

A review of the incidents raised concern that the system fails to detect and warn drivers appropriately when the visibility of the vehicle’s cameras is degraded, the National Highway Traffic Safety Administration said in a memo posted to its website. The agency this week upgraded its probe, started in 2024, to what it calls an engineering analysis.
