THE SPEEDOMETER STOPS WORKING CORRECTLY. WHILE TRAVELING AT HIGHWAY SPEEDS THE SPEEDOMETER WILL READ ANYWHERE BETWEEN BELOW 0 MPH AND 30 MPH. IT HAPPENS REGARDLESS OF THE WEATHER. THERE HAVE BEEN MULTIPLE OCCURRENCES THAT THE SPEEDOMETER IS WORKING CORRECTLY, (CONFIRMED BY CALCULATIONS USING TIME, MILE MARKERS & ODOMETER READINGS,) AND AT ANY POINT DURING TRAVEL IT WILL STOP AND THE NEEDLE IS OBSERVED TO GRADUALLY DROP BELOW THE 0 MPH MARK. SOMETIMES RESTARTING, WHETHER BY TURNING OFF THE IGNITION OR USING THE AUTOSTART TO REMOVE THE KEY WHILE LEAVING THE VEHICLE RUNNING, WILL TEMPORARILY CORRECT THE PROBLEM. THE PROBLEM WAS NOTED BY AN INDEPENDENT MECHANIC AT THE END OF SEPTEMBER WHILE ADDRESSING POTENTIAL TRANSMISSION ISSUES. (WHICH ALSO HAS NOT BEEN RESOLVED. THE MECHANIC WAS UNABLE TO FIND A CAUSE TO "HARD SHIFT" PROBLEM THAT BEGAN SEVERAL MONTHS AGO.) THE CURRENTLY MILEAGE ON THE VEHICLE IS APPROXIMATELY 81,200 MILES. IT IS BEING TAKEN TO A MECHANIC THIS WEEK TO ADDRESS THE ISSUE. *TR

I HAD A TRANSMISSION REPAIR AT AN AMMCO TRANSMISSION OUTLET. AS A RESULT OF THE REPAIR MY INSTRUMENT CLUSTER WAS NOT WORKING THE FIRST DAY THE CAR WAS DECLARED REPAIRED. I LEFT THE CAR WITH THE REPAIRER WHO TOLD ME A SECOND TRANSMISSION WOULD BE INSTALLED. I WAS TOLD APPROXIMATELY TEN DAYS LATER MY CAR WAS REPAIRED. WHEN THE CAR WAS PICKED UP A SECOND THE TIME THE PROBLEM WAS NOT RESOLVED. I WAS TOLD IT NEEDED TO TIME FOR THE COMPUTER TO RESET ITSELF. THAT NEVER HAPPENED SINCE I FOUND OUT LATER THAT THE COMPUTER WAS IN DEFAULT MODE AND WAS NOT COMMUNICATING WITH THE TRANSMISSION. AAMCO PRETENDED TO TELL ME MY CAR WAS SAFE TO DRIVE THROUGHOUT THIS ORDEAL. THE SAME NIGHT I RECEIVED THE CAR BACK MY EXTERIOR LIGHTS WENT WHEN MY CAR GLITCHED AGAIN. I ALMOST HIT THE SIDE OF THE MOUNTAIN BECAUSE THERE WAS TOTAL DARKNESS. MY COMPLAINT IS THAT THERE IS NO OVERSIGHT OF SECONDARY REPAIR SHOPS. I HAVE TRIED HARD. NO ONE SHOULD GO THROUGH WHAT I HAVE BEEN THROUGH. THIS MECHANICS USED MANY EXCUSES BUT IN THE END IT WAS A PINCHED (BEST WORD I CAN UTILIZED) WIRE THAT CAUSED THE PROBLEM. AFTER BEING TURNED DOWN BY FOUR LOCAL MECHANICS THE PROBLEM WAS FIXED BY THE DEALER. NO ONE WAS WANTS TO STEP FORWARD TO EXPLAIN MY PROBLEM. HOWEVER I HAVE DOCUMENTS TO SHOW THAT MY ELECTRICAL SYSTEM WAS WORKING FINE PRIOR TO THIS REPAIR. THE ATTORNEY GENERALS OFFICE IN PA HAS LIMITED AUTHORITY ON THIS ISSUE AND CANNOT HELP ME. THESE PEOPLE NEED OVERSIGHT SOMEONE WILL BE KILLED OR ALREADY HAS. *TR

2004 BUICK RENDEZVOUS AWD LIGHT CAME ON AND HAS NEVER GONE OFF. IT CAME ON WHEN WE HAD LESS THAN 30K MILES ON THE CAR. WE HAVE HAD OUR CAR TO MANY, MANY MECHANICS. NONE ARE ABLE TO FIX THIS PROBLEM. ONE TOLD US WE NEEDED ALL NEW TIRES, WE BOUGHT NEW TIRES, ONE SAID IT WAS THE ALIGNMENT WE HAD IT ALIGNED. ONE MECHANIC WENT THROUGH THE CAR AND CHARGED US 3 HOURS OF LABOR TO TELL US THAT HE DID NOT KNOW WHAT WAS WRONG AND NOTHING APPEARED TO BE WRONG. ANOTHER SUGGESTED WE CONTACT THE DEALER MUST BE A CENTRAL COMPUTER SYSTEM DEFECT. CALLED THE DEALER AND HE STATED THERE WERE NO WARNINGS ON THIS DEFECT. AWD IS SOMETHING WE WANTED WHEN WE PURCHASED THE VEHICLE. I HAVE DONE A LOT OF RESEARCH ONLINE AND MANY OTHER OWNERS OF THIS VEHICLE HAVE HAD THE SAME PROBLEM MANY, MANY MECHANICS AND NO FIX TO THE PROBLEM. THE OWNER'S MANUAL STATES THAT WITHOUT THIS WORKING IT POSES A SAFETY HAZARD TO THE DRIVER AND OCCUPANTS.

ON NOVEMBER 10, 2004, THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED A PRELIMINARY EVALUATION TO INVESTIGATE THE FAILURE, MALFUNCTION, OR OTHER UNSATISFACTORY PERFORMANCE OF THE ENGINE CONTROL SYSTEM WHICH MAY RESULT IN ENGINE STALLING IN CERTAIN MODEL YEAR (MY) 2004 BUICK RENDEZVOUS (GMT250) AND PONTIAC AZTEK (GMT250) VEHICLES ALLEGEDLY CAUSED BY IGNITION RELAY FAILURE.ODI IS AWARE OF 68 NON-DUPLICATIVE COMPLAINTS AND 1092 WARRANTY CLAIMS RELATED TO THE SUBJECT ISSUE.THERE ARE NO KNOWN CRASHES RELATED TO IGNITION RELAY FAILURE ON THE SUBJECT VEHICLES.BY LETTER DATED APRIL 19, 2005, GENERAL MOTORS CORP. (GM) HAS NOTIFIED ODI THAT IT WILL CONDUCT A SAFETY RECALL (NTHSA RECALL NO. 05V-157) TO REPLACE DEFECTIVE IGNITION RELAY MODULES IN APPROXIMATELY 34,996 SUBJECT VEHICLES BUILT BETWEEN OCTOBER 13, 2003 AND MARCH 8, 2004.THIS PERIOD OF VEHICLE PRODUCTION IS ASSOCIATED WITH ESCALATED WARRANTY CLAIMS RATES AND COMPLAINTS THAT ALLEGE ENGINE STALL DUE TO IGNITION RELAY FAILURE.GM HAS IDENTIFIED PARTS SUPPLIERS WHO USED MATERIALS CONTAINING SILICONE IN THE MANUFACTURE OF SPECIFIC COMPONENTS FOR THE IGNITION RELAY MODULE.SILICONE CONTAMINATION CAN RESULT IN SILICA DEPOSITS FORMING ON THE CONTACTS AS THE RELAY SWITCHES AND THE HEAT GENERATED BY THE RESULTANT ARC CONVERTS THE SILICONE TO SILICA.SILICA BUILD-UP ON THE CONTACTS IS PROGRESSIVE AND MAY PRODUCE A VOLTAGE DROP ACROSS THE RELAY SUFFICIENT TO CAUSE AN INTERMITTENT NO-START OR ENGINE STALL CONDITION.WARRANTY ANALYSIS INDICATES THE INCIDENCE OF NO/HARD START VERSUS ENGINE STALL TO BE EQUAL.ANALYSIS OF TOWING CLAIMS AND DETAILED SERVICE RECORDS INDICATES THAT VEHICLES MAY EXPERIENCE RESTART DIFFICULTIES AFTER A STALLING INCIDENT APPROXIMATELY 20-30 PERCENT OF THE TIME.THE USE OF SILICONE MATERIALS IN THE MANUFACTURE OF THE SUBJECT IGNITION RELAY HAS BEEN DISCONTINUED.THE ACTION TAKEN BY GM IS SUFFICIENT TO RESOLVE THE ISSUES RAISED BY THIS INVESTIGATION.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.
