NHTSA Investigation PE15012

Passenger Front Air Bag Suppression

The Office of Defects Investigation opened this investigation on April 10, 2015 based on 26 Vehicle Owner Questionnaire reports involving the passenger frontal air bag in MY 2012 Subaru Impreza vehicles.These vehicles use a capacitive type Occupant Detection System (ODS), which is intended to classify the occupant of the passenger seat as either full sized, small stature, a child seat, or other object.The reports alleged that the ODS failed to operate properly and incorrectly suppressed (turned off) the front passenger air bag when the seat was occupied.In a frontal crash sufficient to warranty deployment, a suppressed air bag may increase the risk of injury to the occupant of the seat.On June 25, 2015, Subaru of America, Inc. submitted a Defect Information Report (DIR) advising NHTSA that it would conduct a safety recall to remedy the ODS in 32,400 MY 2012 Subaru Impreza vehicles equipped with a capacitance type ODS for the front passenger's seat.The DIR notes that the WRX/STI models are excluded from this recall as they are equipped with a different type (weight-recognition based) ODS for the front passenger's seat. ODI is closing this investigation based on Subaru's recall action.The ODI reports cited above can be viewed at http://www-odi.nhtsa.dot.gov/owners/SearchSafetyIssues under the following ID numbers:10668512, 10668243, 10662987, 10641835, 10640574, 10626384, 10622234, 10621456, 10619273, 10605789, 10604506, 10575908, 10559081, 10557856, 10556661, 10545059, 10538562, 10532118, 10481308, 10478660, 10473662, 10472608, 10470865, 10468157, 10463432, 10672345, 10712288, 10713178, 10731645.
