DT*: THE CONTACT STATED WHILE IDLING AT AN INTERSECTION, THE CHECK ENGINE LIGHT ILLUMINATED AND ON STAR WAS CALLED. THERE WAS AN ADVISORY TO DRIVE THE VEHICLE SLOWLY TO THE NEAREST DEALER. DIAGNOSTIC TESTING WAS PERFORMED AND THEY DETERMINED A CYLINDER WAS LEAKING AND THE HEAD AND VALVE NEEDED TO BE REPLACED. 12,000 MILES AFTER THE FIRST REPAIR, THE IDENTICAL SCENARIO RECURRED. WHEN THE VEHICLE WAS TAKEN TO THE DEALER, THEY DETERMINED THE DIAGNOSTIC CODE WAS THE SAME AS THE PREVIOUS VISIT. ANOTHER CYLINDER WAS LEAKING AND IT NEEDED A HEAD AND VALVE JOB AGAIN. THE SERVICE MANAGER EXPRESSED THE REASON FOR THE RECURRENCE WAS DUE TO THE DESIGN OF THE HEAD WHICH WAS INSTALLED WHEN THE VEHICLE WAS MANUFACTURED AND DURING THE REPLACEMENT. THE MANUFACTURER WAS CONTACTED, AND DETERMINED THAT THERE WAS NOW A NEW PART FOR REPLACEMENT. THE CONTACT WAS CONCERNED THAT THE ORIGINAL PART AND THE NEW PART HAD THE SAME PART NUMBER. *NM

GM IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 HUMMER H3 VEHICLES.

06V417000 · Air Bags:frontal

Oct 31, 2006

CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.

Consequence & remedy

Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.

Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.
