Teslaautonomous driving system Full Self-Driving(FSD) has been under investigation by the National Highway Traffic Safety Administration (NHTSA) since last year.
Now regulators have decided to expand the scope of the existing investigation to include a more complex assessment of performance in low-visibility environments, which is being conducted by the Office of Defect Investigation (ODI).
ReutersAccording to , the main goal is to ensure that the system that identifies the limitations of the vehicle’s cameras works properly and warns the driver to hand over control.
A recently released document raised the possibility of problems with the “degradation detection” function, especially in situations where visibility is limited due to glare or airborne particles.
This feature was developed to monitor camera performance and notify when autonomous driving is no longer reliable. However, in some cases, it was found that there was a possibility that these adverse conditions were not recognized or that appropriate warnings were not provided to the driver before the accident occurred.
After a fatal accident involving FSD in 2024, Teslahas begun developing a system update. However, it is not clear which vehicles received the improvements, according to NHTSA.
The latest survey, which began in October 2025, is an extension of the previous survey that began in 2024. A massive recall has occurred, affecting virtually all Tesla The vehicle was affected.
TeslaEven as the company continues to pursue development of more advanced autonomous driving systems, the NHTSA investigation could impact the company’s plans by introducing new regulations and standards related to autonomous driving modes.
