NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA25-002.

On March 7, 2024, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24008) to assess reports of inadvertent activation of the Automatic Emergency Braking (AEB) system in model year 2019-2022 Honda Insight and 2019-2022 Honda Passport vehicles. The complainants allege activation of the AEB system with no apparent obstruction in the vehicle's path, resulting in rapid vehicle deceleration. Honda indicated that it is aware of a total of 412 reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and stated that some customers possibly had an inadequate understanding of the AEB system and its limitations. However, many consumer complaints received by ODI allege that Honda dealerships were unable to reproduce the condition or state that Honda dealerships informed the consumer that this is considered normal AEB operation. To date, ODI has received a total of 106 consumer complaints of inadvertent activation of AEB in the subject vehicles.

In total, ODI reviewed 475 reports involving vehicles with unique VINs that may relate to the alleged defect. Of the reports reviewed by ODI, three (3) allege a crash caused by the inadvertent activation of AEB and two (2) allege injury. This Engineering Analysis is being opened to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. Further, the scope of the investigation is being expanded to include assessment of model year 2023 Honda Passport 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.
