On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles.? The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X, XXX reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and alleges that some customers possibly had an inadequate understanding of the CMBS and its limitations. ?However, many consumer complaints allege that Honda dealerships were unable to reproduce the condition or state that they were informed that this is considered normal CMBS operation. To date, ODI has received a total of 1,081 consumer complaints of inadvertent activation of CMBS in the subject vehicles.? A total of 24 complaints alleged a crash and 42 alleged an injury.? The Total column in the Failure Report Summary removes duplicate reports and shows the total number of reports with unique VINs from all Manufacturer, ODI, and EWR data sources.? In some cases, there were multiple reports associated with a particular vehicle in which recurring failures were alleged.? In total, there were X, XXX reports, 84 injury incidents and 40 crashes involving vehicles with unique VINs that may relate to the alleged defect. PE22003 has been upgraded to an Engineering Analysis (EA24002) to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations.? Further the scope has been expanded to include assessment of model year 2020-2022 Honda CR-V and Accord vehicles.
