NHTSA Investigation PE13021

Occupant Classification System Failure

Suzuki Motor of America is conducting a safety recall to remedy the occupant classification system's (OCS) sensor mats in approximately 193,936 model year 2006-2011 Suzuki Grand Vitara and 2007-2011 Suzuki SX4 vehicles (see NHTSA recall 13V-405 for more details).The sensor mat installed in the front passenger seat can develop an electrical circuit disconnection as a result of repeated flexing of the seat from use of the seat.According to Suzuki, when the failure occurs, the OCS system, by design, will not suppress the frontal passenger air bag for a seated child or small-stature adult.A deploying passenger air bag can cause serious injury to such an occupant.The recall population excludes those vehicles that previously had proper remedies under the special coverage campaign for this issue (~11,600) that began in July 2012.The recall remedy will be to install a new front passenger seat cushion assembly that includes an improved OCS sensor mat and an OCS control module with updated algorithms designed to properly identify the type/size of the seated occupant.Consequently, this recall action will address various OCS related problems, including a programming error (associated with diagnostic trouble code B1318) related to detecting a change or shifting in load on the front passenger seat in the model year 2009 Grand Vitara and SX4 vehicles.This Preliminary Evaluation is closed.The ODI reports cited above can be reviewed online at http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers: 10178750, 10185778, 10200217, 10200123, 10206368, 10217021, 10250561, 10254251, 10263756, 10283309, 10285166, 10294320, 10316125, 10323718, 10324530, 10326910, 10332645, 10347204, 10348957, 10349038, 10350237, 10353604, 10354901, 10355400, 10364190, 10367631, 10369777, 10371056, 10373558, 10375165, 10375789, 10376071, 10376621, 10378154, 10380794, 10382860, 10392447, 10392434, 10392599, 10393975, 10395430, 10395602, 10395821, 10395983, 10398172, 10400092, 10400035, 10401106, 10401424, 10404772, 10405359, 10406459, 10407500, 10409412, 10409993, 10413235, 10418162, 10419237, 10419578, 10425035, 10425212, 10426703, 10434905, 10435090, 10435091, 10437600, 10437892, 10437994, 10438100, 10438501, 10438613, 10439357, 10439979, 10440088, 10442968, 10442759, 10442883, 10443173, 10443592, 10443594, 10444434, 10445034, 10445447, 10446215, 10446580, 10447689, 10448161, 10448446, 10448499, 10448554, 10449238, 10450746, 10451260, 10452961, 10453168, 10453403, 10453376, 10454445, 10454978, 10455231, 10455529, 10456043, 10456367, 10456407, 10459063, 10460417, 10460510, 10462016, 10463337, 10464941, 10464693, 10467988, 10468641, 10479583, 10479929, 10481120, 10484053, 10484863, 10486369, 10486729, 10487379, 10491755, 10499622, 10506034, 10508282, 10511057, 10511439, 10512962, 10521656, 10521779, 10523512, 10523931, 10524266, 10526435, 10533196, 10535513, 10537314, 10537619, 10543672, 10544287.
