NHTSA Closes Tesla Smart Summon Probe After Software Updates Address Concerns

NHTSA closed its preliminary investigation into Tesla's Actually Smart Summon remote-parking feature on April 6, citing six over-the-air software updates that materially reduced the risk of low-speed crashes that triggered federal scrutiny in early 2025.

The investigation, designated PE24033, covered approximately 2.59 million Tesla vehicles spanning 2016-2025 Model S and X, 2017-2025 Model 3, and 2020-2025 Model Y models equipped with the Full Self-Driving package. NHTSA's Office of Defects Investigation documented 159 total incidents during the review, 97 of which involved crashes. Every one resulted only in minor property damage; the agency found zero injuries and zero fatalities across the entire incident population.

The pattern that drew regulators' attention was consistent: vehicles struck obstacles such as parked cars, garage doors, or gates, typically during the early moments of a Summon session when the system's camera-based perception had limited situational awareness. Actually Smart Summon, released as an over-the-air update in September 2024, relies exclusively on cameras, a departure from the earlier Smart Summon version that also used ultrasonic sensors no longer fitted to newer Tesla vehicles. That hardware change made the software's ability to detect and respond to nearby obstacles especially consequential.

Tesla responded by deploying six software updates over the course of the investigation, targeting obstacle detection, camera blockage identification, and the system's handling of dynamic objects such as automated gates. The fixes also addressed errors caused by environmental interference, including snow and condensation on camera lenses. NHTSA found the cumulative effect of those changes sufficient to close the probe without issuing a recall.

Critically, the closure carries a specific legal meaning that falls well short of a clean bill of health. NHTSA stated that shutting the investigation does not constitute a finding that a safety-related defect does not exist, and the agency reserved the right to reopen it. For owners using the feature in crowded parking lots or narrow driveways, that distinction matters: Actually Smart Summon remains a tool requiring continuous operator supervision through the Tesla smartphone app, and the agency's sign-off applies only to the specific failure behaviors addressed by those six updates.

The decision represents a partial reprieve for Tesla at a moment of sustained regulatory pressure. Separately, NHTSA last month upgraded its investigation into Tesla's broader Full Self-Driving package to an engineering analysis, a more advanced review stage that typically precedes a potential recall, expanding that scrutiny to approximately 3.2 million vehicles. Closing the Summon probe reduces Tesla's near-term recall exposure on that specific feature while leaving the larger FSD questions unresolved.

For the wider auto industry, the case establishes a working precedent on how regulators evaluate over-the-air remediation: rapid, targeted software fixes addressing documented failure modes can satisfy federal standards and avert formal recall action. The bar, as this probe illustrated, is demonstrating measurable behavioral change in the specific scenarios that generated the complaint data. With low-speed automated maneuvering features spreading across manufacturers, that regulatory framework will almost certainly face further tests.
