NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Recall Query RQ24-009.
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 deployment of a multipart remedy aimed at improving system and engagement controls and reducing mode confusion. EA22002 (upgraded from PE21020) was opened to investigate whether Tesla’s Autopilot contained a defect that created an unreasonable risk to motor vehicle safety and involved extensive crash analysis, human factors analysis, vehicle evaluations, and assessment of vehicle control authority and driver engagement technologies. The work conducted in these investigations aligns with Tesla’s conclusion in its 23V838 recall filing. During EA22002, ODI identified at least 13 crashes involving one or more fatalities and many more involving serious injuries in which foreseeable driver misuse of the system played an apparent role. Tesla filed Recall 23V838 to address concerns regarding the Autopilot system investigated in EA22002. Following deployment of the remedy in Recall 23V838, ODI identified concerns due to post-remedy crash events and results from preliminary NHTSA tests of remedied vehicles. Also, Tesla has stated that a portion of the remedy both requires the owner to opt in and allows a driver to readily reverse it. Tesla has also deployed non-remedy updates to address issues that appear related to ODI’s concerns under EA22002. This investigation will consider why these updates were not a part of the recall or otherwise determined to remedy a defect that poses an unreasonable safety risk. ODI is therefore opening this Recall Query investigation to further evaluate the adequacy of the remedy for recall 23V838.
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Recall Query RQ24-009. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
