Tesla preliminary evaluation PE16007

Automatic vehicle control systems. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the adaptive cruise control on 4 model years (2014–2016). Opened Jun 28, 2016, closed Jan 19, 2017 after 7 months without a recall. closed

What NHTSA says

Source: Office of Defects Investigation, as filed

On May 7, 2016, a 2015 Tesla Model S collided with a tractor trailer crossing an uncontrolled intersection on a highway west of Williston, Florida, resulting in fatal injuries to the Tesla driver. Data obtained from the Model S indicated that:1) the Tesla was being operated in Autopilot mode at the time of the collision; 2) the Automatic Emergency Braking (AEB) system did not provide any warning or automated braking for the collision event; and 3) the driver took no braking, steering or other actions to avoid the collision. On June 28, 2016, NHTSA opened PE16-007 to ?examine the design and performance of any automated driving systems in use at the time of the crash.?The Office of Defects Investigation (ODI) analyzed the following subjects as part of NHTSA?s examination of the design and performance of Tesla?s Autopilot system:1) Automatic Emergency Braking (AEB) system design and performance in the subject Tesla and peer vehicles; 2) human-machine interface issues related to Autopilot operating mode; 3) data from crash incidents related to Tesla?s Autopilot and AEB systems; and 4) changes Tesla has implemented in the Autopilot and AEB systems. NHTSA?s examination did not identify any defects in the design or performance of the AEB or Autopilotsystems of the subject vehicles nor any incidents in which the systems did not perform as designed. AEB systems used in the automotive industry through MY 2016 are rear-end collision avoidance technologies that are not designed to reliably perform in all crash modes, including crossing path collisions. The Autopilot system is an Advanced Driver Assistance System (ADAS) that requires the continual and full attention of the driver to monitor the traffic environment and be prepared to take action to avoid crashes. Tesla's design included a hands-on the steering wheel system for monitoring driver engagement. That system has been updated to further reinforce the need for driver engagement through a strike out strategy. Drivers that do not respond to visual cues in the driver monitoring system alerts may strike out and lose Autopilot function for the remainder of the drive cycle. A safety-related defect trend has not been identified at this time and further examination of this issue does not appear to be warranted. Accordingly, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists. The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances. For more information about the analysis, see the attached report.

A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the resumes carrying the full reasoning are linked below.

These are NHTSA’s own files, served from the agency’s site — the resumes are what ODI wrote when it opened and closed the action, and the rest is the correspondence behind them, including what the manufacturer sent when the agency asked. They are linked, not copied: where a document names the people who wrote in, that redaction is the agency’s to make and its copy is the one you should read.

What owners had already reported

Source: complaints on file the day it opened

When NHTSA opened this on Jun 28, 2016, owners had filed 22 complaints with the agency about the model years above. Owner complaints are the agency’s main early signal: ODI screens them, and a Preliminary Evaluation is usually where a pattern in them ends up.

This is what the complaint file held on that date, not a claim about which reports prompted the investigation — NHTSA’s complaint records carry no investigation number, so nobody can make that link from the data alone. The opening resume linked above names the reports ODI itself cited. Complaint records on this site begin with 2016.

What this means for an owner

Source: and what happens next

An investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.

This one closed without a recall. That means NHTSA found no defect trend it chose to act on at the time, or the manufacturer addressed the condition another way (a service campaign or a bulletin, which have their own pages). A closed file can be reopened if new reports arrive.

Model years it names

Also named on model years this site has no page for: 2014 Tesla Model S; 2015 Tesla Model S.

A vehicle page’s investigation list carries the same action; a name here is the scope NHTSA opened, not a list of affected VINs.

Common questions

Source: NHTSA Office of Defects Investigation

Is PE16007 a recall?

No. A preliminary evaluation is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one closed without one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.

Is PE16007 still open?

No. It closed on Jan 19, 2017 without a recall.

Which vehicles does PE16007 cover?

NHTSA opened it on 4 model years: 2016 Tesla Model S, 2016 Tesla Model X, 2014 Tesla Model S, 2015 Tesla Model S. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
