NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE20-020.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
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.

Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Preliminary Evaluation PE20-020. 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.
