What the hazard is
If the frontal airbags and seatbelt pretensioners do not deploy when required, there is an increased risk of injury to occupants in a crash.
What to do
Owners should present their vehicle to an authorised dealer or contact Performax International to arrange for repair procedure, which will reprogram the SDM with new software that eliminates this defect. In vehicles with any previous deployment events recorded in the SDM, the dealers will replace the existing SDM with a new SDM containing the latest software.
Defect
The sensing and diagnostic module (SDM) in these vehicles, which controls airbag and pretensioner deployment, contains a software defect which may prevent the deployment of frontal airbags and pretensioners in certain circumstances.
