This investigation was opened on Jun. 16, 2009.
It was closed on Dec. 8, 2009.
Note: this investigation has resulted in
a vehicle safety recall. During preliminary evaluation pe09-030, isuzu motors America, inc (isuzu) noted two primary differences once the rear suspension lower link separation occurs between the alleged defect (separation of the lower link from the frame) of this investigation and a safety defect involving lower link separation from the rear axle addressed by isuzu in safety recall 00v-058. In the case of the defect condition identified in recall 00v-058, isuzu stated that the attachment bolt could detach fully, causing separation of the lower link from the rear axle possibly creating a loss of vehicle control. Isuzu also stated that this condition occurs early in the service life of the vehicle. In this investigation isuzu noted lower link separation from the frame is a progressive corrosion issue with prior warning to consumers. Isuzu also stated that in the event of a lower link separation from the frame, the vehicle is still controllable and can be safely stopped. The office of defect investigation (odi) analyzed complaint data provided by isuzu and America Honda motor company, inc (Honda), as well as vehicle owner questionnaires submitted to odi from consumers. In total, there were 60 unique reports of lower link separations from the frame including 1 alleged crash and 7 loss of vehicle control incidents that may be related to the alleged defect. Most of these complaints indicated that there was no warning prior to the link separation. This preliminary evaluation has been upgraded to an engineering analysis (ea09-018) to further assess the scope, frequency and risk to motor vehicle safety of the alleged defect in the subject vehicles. |
