Key parties include NHTSA as the regulator, Tesla as the company that developed and updated ASS via over-the-air software fixes improving obstacle detection, camera blockages, and responses to dynamic objects or environmental factors like snow.[2][4][5][6][7] ASS, a vision-based upgrade to original Smart Summon rolled out in September 2024, lets owners remotely summon their car in parking lots or private property via the Tesla app while requiring continuous supervision.[1][3][5]
The investigation opened in January 2025 following crash reports, including a December 2024 Maryland incident highlighting safety concerns with the app-based self-parking feature.[1][3][4][5][7] Tesla's software updates addressed issues, leading NHTSA to close the probe without finding a systemic defect, though it reserves rights for future action.[2][4][6]
Newsworthy amid ongoing NHTSA scrutiny of Tesla's autonomy tech, including a recent upgrade to engineering analysis of Full Self-Driving (covering 3.2 million vehicles) and rejection of an unintended acceleration recall petition, this closure signals a regulatory win for ASS while broader driver-assistance systems face heightened review.[2][6][7]
