Volkswagen engineering analysis EA24004

Inadvertent Automatic Emergency Braking. NHTSA’s Office of Defects Investigation opened this engineering analysis about the automatic emergency braking on 1 model year (2019). Opened Dec 18, 2024 and still open — 21 months so far, against NHTSA’s goal of eighteen months for a engineering analysis. open

On 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 226 reports that may relate to the alleged defect in MY 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 stated that 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. To date, ODI has received a total of 44 consumer complaints of inadvertent activation of Front Assist in MY 2019 Volkswagen Atlas vehicles.In total, ODI reviewed 187 unique (i.e., non-duplicative Vehicle Identification Numbers) reports that may relate to the alleged defect, which include four reports on injury incidents and one report involving a crash. PE23017 has been upgraded to an Engineering Analysis to further assess the scope, frequency, and potential safety-related consequences of inadvertent AEB activations in MY 2019 Volkswagen Atlas vehicles.

A Engineering Analysis is the deeper stage, usually upgraded from a Preliminary Evaluation: NHTSA tests, requests engineering documents and decides whether a safety defect exists. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.

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 is open. Nothing is owed on the vehicle today; if it becomes a recall, owners are written to and the repair is free. The moment to know is the day the campaign number appears — Recall Watch checks each VIN against every new NHTSA campaign and emails you when one lands, or take a free one-line alert by model year.

Common questions

Source: NHTSA Office of Defects Investigation

Is EA24004 a recall?

No. A engineering analysis is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one has not produced one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.

Is EA24004 still open?

Yes, as of NHTSA’s latest file: opened Dec 18, 2024, 21 months ago.

Which vehicles does EA24004 cover?

NHTSA opened it on 1 model year: 2019 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.
