NHTSA investigation PE22002 is a Preliminary Evaluation opened on 2022-02-16 and currently open. The subject of record is TESLA MODEL 3, which places this file inside the Office of Defects Investigation queue for TESLA. Latest activity on this investigation was logged on 2022-02-16 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.

A Preliminary Evaluation like PE22002 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.

Investigators summarized the matter as follows: "The Office of Defects Investigation (ODI) has received 354 complaints alleging unexpected brake activation in 2021-2022 Tesla Model 3 and Model Y vehicles. Received over the past nine months, the reports have often been..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related TESLA files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

The Office of Defects Investigation (ODI) has received 354 complaints alleging unexpected brake activation in 2021-2022 Tesla Model 3 and Model Y vehicles. Received over the past nine months, the reports have often been characterized as “phantom braking” by consumers. Tesla describes the subject vehicles as equipped with a suite of advanced driver assistance system (ADAS) features referred to as Autopilot which Tesla states will allow the vehicle to brake and steer automatically within its lanes. The complaints allege that while utilizing the ADAS features including adaptive cruise control, the vehicle unexpectedly applies its brakes while driving at highway speeds. Complainants report that the rapid deceleration can occur without warning, at random, and often repeatedly in a single drive cycle. ODI is opening this Preliminary Evaluation (PE) to determine the scope and severity of the potential problem and to fully assess the potential safety-related issues. The ODI reports cited above are available to review online at NHTSA.gov under ODI identification numbers listed in the attachment to this resume.

About This Investigation Type

A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
