## NHTSA's summary

"12187C \- CUSTOMER SATISFACTION PROGRAM \(REVISED EXPIRATION DATE\). CERTAIN VEHICLES THAT WERE SERVICED WITH AN INCORRECT CALIBRATION, MAY HAVE A CONDITION IN WHICH THE AUTOMATIC CRASH RESPONSE SYSTEM MAY NOT WORK AS INTENDED BECAUSE OF A SOFTWARE PROBLEM. THE AUTOMATIC CRASH RESPONSE SYSTEM IS INTENDED TO ENABLE THESE VEHICLES TO NOTIFY ONSTAR® IF THEY ARE INVOLVED IN CERTAIN TYPES OF CRASHES. THE SOFTWARE PROBLEM WE FOUND AFFECTS THE VEHICLE’S ABILITY TO NOTIFY ONSTAR® IN CRASHES THAT MEET THE SEVERITY PARAMETERS FOR AUTOMATIC CRASH NOTIFICATION BUT DO NOT TRIGGER AIRBAG DEPLOYMENT, SUCH AS CERTAIN REAR END CRASHES. IN CRASHES WITH AN AIRBAG DEPLOYMENT, THE AUTOMATIC CRASH RESPONSE SYSTEM WORKS AS DESIGNED. THIS CONDITION DOES NOT AFFECT THE DEPLOYMENT OF THE AIRBAGS OR THE SAFETY BELT PRETENSIONERS, WHICH REDUCE SLACK IN THE SAFETY BELT IMMEDIATELY AFTER IMPACT. THE AIRBAGS AND SAFETY BELT PRETENSIONERS WILL DEPLOY AS DESIGNED. A VEHICLE OCCUPANT WILL BE ABLE TO CONTACT AN ONSTAR® EMERGENCY ADVISOR BY PUSHING THE ONSTAR® EMERGENCY BUTTON. DEALERS ARE TO REPROGRAM THE SENSING AND DIAGNOSTIC MODULE \(SDM\)."
