NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA24-004.

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.

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.
