The US National Highway Traffic Safety Administration has closed its investigation into Tesla's Smart Summon feature after documenting 159 incidents across approximately 2.6 million vehicles. Despite 97 crashes, the regulator found zero injuries and zero fatalities, concluding that Tesla's over-the-air software updates adequately addressed the issues.

Investigation Timeline

The probe, designated PE24033, launched in January 2025 and covered 2016–2025 Model S and X, 2017–2025 Model 3, and 2020–2025 Model Y vehicles equipped with Full Self-Driving capability. NHTSA noted that the 159 incidents represented "a fraction of 1%" of millions of Smart Summon sessions.

What Went Wrong

The investigation identified several failure modes. Camera blockages from snow and condensation caused collisions with parked vehicles. The system failed to detect obstructed forward-facing cameras in winter conditions. Smart Summon also struggled with yielding for parking garage gate arms and other low-profile obstacles.

Tesla's OTA Fixes

Tesla deployed six over-the-air software updates during 2025 to address the identified issues:

Date Update Fix
January 15 578998, 579185 Camera blockage detection
January 20 SW-578752 Snow/condensation handling
January 30 SW-580322 Additional weather scenarios
February 6 SW-578839 Gate perception systems
November 20 SW-580514 Object detection enhancements

European Implications

Smart Summon has not been widely available in Europe due to stricter regulations around remote vehicle movement in public spaces. The NHTSA closure may strengthen Tesla's case with European regulators as FSD approval approaches, though EU and national authorities apply their own safety standards independently.

Not a Clean Bill of Health

NHTSA explicitly reserved the right to reopen the investigation based on future developments. The closure reflects "low incident occurrence and low incident severity" rather than a finding that Smart Summon is free of issues. Almost all crashes involved minor property damage, and no vulnerable road users were affected.
