NHTSA investigation PE20020 is a Preliminary Evaluation opened on 2020-11-22 and currently closed. The subject of record is TESLA MODEL S, which places this file inside the Office of Defects Investigation queue for TESLA. Latest activity on this investigation was logged on 2024-08-12 — 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 PE20020 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) opened this Preliminary Evaluation based on forty-three complaints alleging failure of the left or right front suspension fore links in Tesla model year (MY) 2015 through 2017 Mo..." 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) opened this Preliminary Evaluation based on forty-three complaints alleging failure of the left or right front suspension fore links in Tesla model year (MY) 2015 through 2017 Model S and MY 2016 through 2017 Model X vehicles. The investigation has identified 426 instances of failure on part number 1041570-00-A or 1041575-00-A fore links. None of the instances resulted in any loss of vehicle control. One minor crash with no injuries is associated with the 426 instances fore link failures. A majority of the failures occurred between one to fifteen mph while parking in driveways or parking lots. In the eight instances where the vehicle was traveling more than 40 mph and the fore link failed, the vehicle remained controllable with no associated crash or injuries as a result. Tesla issued a consumer satisfaction bulletin (SB-17-31-001) on 10 February 2017, to replace the subject component on a sub-population of vehicles originally equipped with the subject fore links and built between 19 January 2016 and 25 May 2016. This sub population does not cover 75% instances of failures identified in this investigation. Additional damage to other vehicle components will occur if the vehicle is driven with this failed fore link. However no instance has shown that a failure of the fore link in this manner prevented the controllability of the vehicle in testing and reported failures. Based on this analysis, ODI is closing the investigation. ODI recommends that Tesla expand the terms of Bulletin SB-17-31-001 to cover all vehicles equipped with 1041570-00-A or 1041575-00-A fore links. This does not constitute a finding by the Agency that a safety-related defect is not present; the Agency will take further action if warranted by additional information received.

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.
