The Office of Defects Investigation (ODI) is opening this Engineering Analysis to evaluate Tesla’s Full Self Driving Beta and Full Self Driving (Supervised) (collectively, FSD) degradation detection system. The focus of this investigation will be to assess the system’s ability, when encountering reduced roadway visibility conditions, to detect degradation and alert the driver with sufficient time to respond. ODI will evaluate the performance of FSD in degraded roadway conditions and the updates or modifications by Tesla to the degradation detection system, including the timing, purpose, and capabilities of the updates, and Tesla’s assessment of their safety impact. Tesla’s FSD is an advanced

The Office of Defects Investigation (“ODI”) is opening this Preliminary Evaluation (PE) to assess the scope, frequency, and potential safety consequences of FSD executing driving maneuvers that constitute traffic safety violations. This investigation concerns versions of FSD that Tesla has labeled as "FSD (Supervised)" and "FSD (Beta)." Tesla characterizes FSD as an SAE Level 2 partial automation system requiring a fully attentive driver who is engaged in the driving task at all times. Level 2 partial automation systems are designed to support and assist the driver in performing certain aspects of the driving task, requiring a driver to supervise and intervene as necessary.  The driver remains

The Office of Defects Investigation (“ODI”) has identified numerous incident reports submitted by Tesla, Inc. (“Tesla”) in response to Standing General Order 2021-01 (the “SGO”), in which the reported crashes occurred several months or more before the dates of the reports. The majority of these reports involved crashes in which the Standing General Order in place at the time required a report to be submitted within one or five days of Tesla receiving notice of the crash. When the reports were submitted, Tesla submitted them in one of two ways. Many of the reports were submitted as part of a single batch, while others were submitted on a rolling basis. Preliminary engagement between ODI and T

On January 6, 2025, the Office of Defects Investigations (ODI) opened Preliminary Evaluation 24003 (PE24033) to investigate Actually Smart Summon (Summon) sessions resulting in crashes during active sessions. According to Tesla, Summon is a short-distance SAE Level 2 system, controlled by the user from a cell phone within a certain distance and intended for use in parking lots and on private property. ODI analyzed complaint data provided by Tesla as well as complaints submitted to ODI from consumers to identify Summon incidents resulting in crashes. ODI's analysis indicates that almost all Summon reported crashes involved minor property damage claims with no reported incidents involving a vu

The Office of Defects Investigation (ODI) is opening a Recall Query to assess the remedy adequacy of Recall 23V838. On December 12, 2023, Tesla filed a Defect Information Report (Recall 23V838) applicable to all Tesla models produced and equipped with any version of its Autopilot system, which Tesla described as an SAE Level 2 (L2) Advanced Driver Assistance System (ADAS). Autopilot is the simultaneous engagement of Tesla’s Traffic-Aware Cruise Control (TACC) and Autosteer. In describing the safety defect, Tesla’s Defect Information Report (DIR) explained that “the prominence and scope of the system’s controls may be insufficient to prevent driver misuse,” and Tesla committed to the deployme

The Office of Defects Investigation (ODI) received a petition requesting that ODI reevaluate its decision to deny DP20-001 on the basis that intermittent high electrical current demands on the vehicles' 12VDC systems may have caused some or all of the incidents examined by ODI in DP20-001. The petitioner bases this information on a review of open-source research and the DP20-001 denial. The petition and related materials can be reviewed at NHTSA.gov under the following ODI number: 11528471.

On March 21, 2023, the Office of Defects Investigation (ODI) received a petition requesting a “recall of all Tesla cars” produced from 2013 to the date on which the petition was filed due to what Petitioner considers to be the increased likelihood of pedal misapplication. Attached to the Petition is a paper authored by Petitioner. According to Petitioner, the differences in the operator controls between the subject Tesla vehicles and internal combustion engine powered vehicles promote driver pedal misapplication, leading to sudden unintended acceleration (SUA) incidents. To fix this alleged defect, Petitioner argues that the subject vehicles should be equipped with measures that require: (i)

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021. On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject mat

The Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE21-023) on December 21, 2021, to evaluate the driver distraction potential and use frequency / circumstances of in-vehicle game-play functionality referred to as ?Passenger Play? in certain model year (MY) 2017-2022 Tesla Model 3, S, X, and Y vehicles. Distracted driving can result in an increased risk of a crash. PE21-023 was prompted by the receipt of Vehicle Owners Questionnaire (VOQ) 11439598 from the owner of a 2021 Model 3 on November 6, 2021. ODI sent an Information Request (IR) letter to Tesla on January 20, 2022 and received Tesla?s response on March 4, 2022. On December 24, 2020, Tesla introduced Passenger P

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf. Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a subst

On August 13, 2021, NHTSA?s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE21-020) to assess the performance of Tesla?s Autopilot system (a system characterized by Tesla as an SAE Level 2 driving automation system designed to support and assist the driver in performing the driving task) available in Tesla vehicles. The investigation opening was motivated by an accumulation of crashes in which Tesla vehicles, operating with Autopilot engaged, struck stationary in-road or roadside first responder vehicles tending to pre-existing collision scenes. Upon opening the investigation, NHTSA indicated that the PE would also evaluate additional similar circumstance crashes of
