US Closes Tesla Autopilot Braking Probe, Citing Low Risk and Declining Incidents
The U.S. National Highway Traffic Safety Administration (NHTSA) has concluded its preliminary assessment initiated in early 2022 concerning unintended braking issues in approximately 695,000 Tesla vehicles. The agency cited a low actual risk to drivers and a significant decrease in the incident rate as reasons for closing the investigation. The probe specifically focused on Tesla Model 3 and Model Y vehicles. According to the NHTSA, Tesla implemented a software update in early 2022 to address the unintended deceleration problem. The number of reported incidents has dramatically fallen since the investigation began. Reports dropped from 300 at the investigation's start to 45 in 2024, 19 in 2025, and only 3 since the beginning of 2026. The NHTSA noted that the described situations did not alter the vehicles' lateral position within their lanes or significantly reduce the distance to following vehicles, thereby mitigating collision risks.
The NHTSA's decision to close the investigation into Tesla's unintended braking incidents highlights the evolving nature of automotive safety oversight in the era of advanced driver-assistance systems. While the agency's assessment of low actual risk and declining incident rates suggests a resolution, it also underscores the challenge of monitoring software-driven vehicle behaviors. The significant reduction in reported issues following a manufacturer-issued software update points to the potential effectiveness of over-the-air fixes. However, the initial high volume of complaints warrants continued vigilance regarding the systemic safety implications of complex software integrations and the efficacy of regulatory frameworks in keeping pace with rapid technological advancements.
