The autonomous driving system Full Self-Driving (FSD) the Tesla has been under investigation by the US National Highway Traffic Safety Administration (NHTSA) since last year.
Now the regulator has decided to broaden the ongoing investigation to include more complex assessments of its performance in low visibility conditions, an analysis conducted by the Office of Defects Investigation (ODI).
Second Reutersthe main objective is to check whether the system responsible for identifying the limits of the vehicle’s cameras is working correctly in alerting the driver to regain control.
Recent documents from the agency point to possible malfunctions in a feature called “degradation detection,” particularly in scenarios with glare or the presence of particles in the air that reduce visibility.
This tool was developed to monitor the performance of cameras and report when autonomous driving is no longer reliable. However, in some cases analyzed, the system may not have recognized these adverse conditions or correctly warned the driver before the accidents.
After a fatal accident involving the FSD in 2024, Tesla has started developing a system update. However, according to the NHTSA, it is unclear which vehicles have received these improvements.
The most recent investigation, launched in October 2025, continues an investigation that began in 2024. Large-scale recalls have been recorded, involving virtually the entire vehicle fleet Tesla in the United States.
While Tesla continues to promote the development of more advanced driving systems, the NHTSA investigation could hinder the company’s plans by introducing new rules and regulations related to autonomous driving modes.
