Volkswagen preliminary evaluation PE23017
Inadvertent Automatic Emergency Braking. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the automatic emergency braking on 6 model years (2018–2023). Opened Sep 28, 2023, closed Dec 18, 2024 after 15 months without a recall. closed
What NHTSA says
Source: Office of Defects Investigation, as filedOn September 28, 2023, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE23017) to assess reports of inadvertent activation of the Front Assist automatic emergency braking (AEB) system in model year (MY) 2018-2019 Volkswagen Atlas vehicles. The reports alleged that activation of the AEB system occurred while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Volkswagen indicated that it is aware of a total of 292 reports that may relate to the alleged defect in MY 2018-2019 Volkswagen Atlas vehicles. Volkswagen stated that some customers possibly had an inadequate understanding of Front Assist and its limitations. However, many consumer complaints alleged that Volkswagen dealerships were unable to reproduce the condition or Volkswagen dealerships informed the consumers that this braking is considered normal Front Assist operation. ODI's analysis shows that MY 2019 Volkswagen Atlas vehicles have the highest rate of unique incident reports alleging AEB inadvertent activation when compared to their Volkswagen peers. The rate of unique incident reports alleging AEB inadvertent activation in MY 2018 Volkswagen Atlas vehicles was comparable to their Volkswagen peers. To date, ODI has received a total of 69 consumer complaints of inadvertent activation of Front Assist in MY 2018-2019 Volkswagen Atlas vehicles. In total, ODI reviewed 264 unique (i.e., non-duplicative Vehicle Identification Numbers) reports that may relate to the alleged defect, which include eight reports of incidents involving an alleged injury and two reports involving a crash. PE23017 has been upgraded to an Engineering Analysis (EA24004) to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations in MY 2019 Volkswagen Atlas vehicles.

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 openedWhen NHTSA opened this on Sep 28, 2023, owners had filed 1,404 complaints with the agency about the model years above, of which 178 named the forward collision avoidance NHTSA went on to investigate. 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 nextAn 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.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE23017 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 PE23017 still open?
No. It closed on Dec 18, 2024 without a recall.
Which vehicles does PE23017 cover?
NHTSA opened it on 6 model years: 2023 Volkswagen Atlas, 2022 Volkswagen Atlas, 2021 Volkswagen Atlas, 2020 Volkswagen Atlas, 2019 Volkswagen Atlas, 2018 Volkswagen Atlas. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
