THE TRAILING ARM DESIGN IN THESE VEHICLES HAS BEEN USED IN THE U-VAN FROM MY 1997 THROUGH THE PRESENT.THE GM ANALYSIS CONCLUDED THAT THE SUBJECT TRAILING ARMS COULD CRACK OR BUCKLE IF THEY WERE DAMAGED DURING ASSEMBLY, PRE-DELIVERY HANDLING, OR SUBJECTED TO CERTAIN SERVICE RELATED ABUSE CONDITIONS SUCH AS IMPROPER TOWING OR JACKING.ANALYSIS OF ODI AND GM DATA HAS IDENTIFIED 19 INCIDENTS OF REAR AXLE TRAILING ARM FAILURES IN THE SUBJECT VEHICLES.THERE HAVE BEEN NO NEW REPORTS TO ODI OR GM IN THE LAST 12 MONTHS AND ONLY ONE NEW COMPLAINT IN THE LAST 21 MONTHS. DUE TO THE LOW COMPLAINT RATE AND THE ABSENCE OF A CONTINUING TREND IN REPORTED FAILURES, A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.

THE INTAKE MANIFOLD GASKET IN OUR 1997 SILHOUETTE WENT BAD. AFTER SPEAKING WITH THE REPAIR FACILITY AND PERFORMING SEVERAL SEARCHES ACROSS THE INTERNET, IT WAS OBVIOUS THAT GM HAD A DEFECTIVE PART. THE ORIGINAL GASKETS WERE MADE OUT OF PLASTICS, WHILE NOW GM IS CONSTRUCTING THEM OF A MORE NORMAL / ACCEPTABLE MATERIAL. WE WERE LUCKY AND CAUGHT THIS EARLY, BUT IF SOMEONE WERE TO HAVE THIS HAPPEN ON A HIGHWAY TRIP, OIL COULD LEAK OUT OR MIX WITH COOLANT CAUSING THE ENGINE TO SEIZE UP AT HIGHWAY SPEEDS. THIS REPAIR AVERAGES AROUND $800 TO $1200 FROM WHAT I COULD FIND. *JB

NO FLOOR HEAT IN 1997 OLDS SILHOUETTE. MECHANIC DID NOT FIND CAUSE OF PROBLEM BUT DID NOTE THAT AN UN ASSOCIATED PROBLEM WAS OCCURING. THE ORIGINAL PLASTIC INTAKE MANIFOLD GASKET WAS FAILING. AFTER INVESTIGATING AND RESEARCHING I HAVE FOUND THAT BOTH THE LACK OF HEAT IN THE FRONT OF THIS VEHICLE AND WORSE YET THE FAILING OF THE GASKET ARE COMMON PROBLEMS WITH THIS VEHICLE. I AM SCHEDULED TO HAVE BOTH PROBLEMS TAKEN CARE OF ON 12/28/2005. THE ESTIMATE (NO TELLSING THE COST TO REPAIR THE HEAT UNTIL THEY GET INTO IT) WILL RUN AT LEAST $700. BASED ON THE PAST INTAKE MANIFOLD GASKET REPAIRS THIS SHOP HAS DONE ON GM VEHICLES THE SHOP ESTIMATES THIS REPAI ALONE WILL COST AT LEAST $500. *NM

FRONT WINDSHIELD HAS BEEN REPLACED TWICE IN 12 MONTHS. BREAK INITIATED IN UPPER DRIVER SIDE CORNER AND TRAVELS INTO FIELD OF VISION. WITH WINDSHIELD OUT, YOU CAN SEE SEVERE RUSTING AT THE CORNER, NO WHERE ELSE. THE RUST IS ALL THE WAY THROUGH THE ROOF PANEL AND IS NOT VISIBLE ONCE THE WINDSHIELD IS REPLACED. I WAS ADVISED NOT TO GO THROUGH ANY CAR WASHES, TO AVOID ANY UNDO PRESSUES ON THE DRIVERSIDE QUARTER OF THE ROOF AND WHEN IT BREAKS AGAIN TO HAVE THE WINDSHIELD REPLACED IN A BODY SHOP WHERE THAT SECTION OF THE ROOF CAN BE REPLACED SO IT WON'T HAPPEN AGAIN. THE WINDSHIELD REPAIR PERSON STATED THAT WHEN HE REPLACES A FRONT WINDSHIELD ON AN OLDS SILHOUETTE OR CHEVY VENTURE THAT IS NOT THE RESULT OF AN ACCIDENT, 99% OF THE TIME THE BREAK INITIATES AT ONE OF THE TOP CORNERS AND WHEN THE WINDSHIELD IS OUT, THERE IS SEVERE RUSTING IN THE SAME SPOTS. GIVEN THE SEVERITY OF THE RUST THROUGH, I EXPECT IT WILL LEAK INTO THE INTERIOR SOON.
