THE ABS WHEEL SPEED SENSOR WIRE HARNESS HAS A FAILURE ISSUE. THIS LEADS TO THE ABS SYSTEM ACTIVATING WITHOUT A WARNING LIGHT TURNING ON AND CAN INCREASE THE STOPPING DISTANCE WHEN NOT NECESSARY. THE TRANSMISSION MAY SEEM TO CLUNK WHEN ACCELERATING FROM A STOP AS THE COMPUTER DOESN'T READ THE CORRECT SPEED SENT FROM THE HUB ASSEMBLY TO THE COMPUTER. PREVIOUSLY, I HAD A HUB ASSEMBLY REPLACED AND THE PROBLEMS STILL EXISTED. AFTER REPLACING THE WIRES THE PROBLEMS HAVE NOT RESURFACED.

TRAC LIGHT WOULD COME ON AND OFF A FEW TIMES. EVENTUALLY THE TRAC OFF, AND ABS LIGHT STAY ON. IT OCCURS AT RANDOM MOMENTS WHILE STATIONARY AND IN MOTION. DISABLING THE TRACTION CONTROL. THIS IS HAZARDOUS WHEN IT IS ON AND IN MOTION WITH NOT FAVORABLE WEATHER IE RAIN OR SNOW. I HAVE HAD THIS HAPPEN TO ME, DRIVING IN THE RAIN WITH THE ABS DISABLED, I HAD TO APPLY MY BRAKES HARD TO AVOID REAR ENDING THE CAR IN FRONT OF ME WHO HAD HIT THEIR BRAKES TO AVOID AN ACCIDENT AS WELL. I HAVE REPLACED HUB ASSEMBLY, ROTORS BRAKES, BRAKE CALIPERS, BRAKE HOSES THE WHOLE NINE YARDS. WAS TOLD BY ONE MECHANIC THAT WHEN THE TRACTION SYSTEM LIGHTS ARE ON AND ABS IS DISENGAGED THIS CAUSES HIGHER WEAR AND TEAR ON THE ROTORS AND BRAKE PADS. WAS ALSO TOLD THAT THE ABS WIRING HARNESS IS TOO SHORT, SO IT GETS PULLED WHEN MAKING TURNS. THIS ISSUE WILL ALSO HAPPEN IF I GO OVER BUMPS, LIKE RAILROAD TRACKS, THE SMALL STREET DITCH FOR RAIN AT THE END OF A DRIVEWAY. SOMETIMES I JUST START THE CAR UP AND IT WILL IMMEDIATELY COME ON. I ALSO HAD THE SIDE SEAR FRONT PASSENGER AIRBAG DEPLOY WHEN A FRIEND CLOSED THE SEATBELT IN THE DOOR. THE CAR WAS IN DRIVE, HOWEVER IT WAS NOT IN MOTION. THE BUCKLE GOT STUCK ON THE FRAME AT THE LOCK LATCH. THE DOOR FLEW BACK OPEN, AIR BAG DEPLOYED, AND ALL INTERIOR LIGHTS ON THE CAR AS WELL AS THE DASH LIT UP.

THREE DAYS LATER THE CAR OVERHEATED AND I GOT IT COMPLETELY CHECKED BY A DIFFERENT MECHANIC TO SEE WHY MY CAR IS RUNNING HOT AND HE GAVE ME A LIST OF PROBLEMS EVERY HEAD GASKET IS BLOWN OUT AND THE MOTOR IS GONE. HE SAID THAT THERE WAS A RECALL A FEW YEARS BACK ON THESE TYPES OF BUICK CARS FOR THE COOLANT AND THE WRONG COOLANT WAS PLACED IN THE CAR AND IT MESSED UP ALL HEAD GASKETS I IMMEDIATELY CALLED THE DEALERSHIP BUT AGAIN NO RESPONSE I CALLED THE BANK BECAUSE I STILL HAVE A 30 DAY TAG AND ONLY HAD THE CAR FOR TWO WEEKS BUT AGAIN NO RESPONSE I CALLED BUICK AND SPOKE WITH SOMEONE TO ASK ABOUT THE COOLANT RECALL AND HE SAID HE WOULD CALL ME BACK IN A HOUR AND AGAIN NO RESPONSE. I ASKED FOR A CARFAX REPORT AND THE DEALERSHIP SAID THEY DIDN'T HAVE ONE BUT GAVE THE COUPLE BEHIND ME A CARFAX FOR THEIR CAR THE BRAKES AND ROTORS ARE COMPLETELY GONE I CANNOT STOP WITH MY BRAKES I JUST HAVE TO COAST SO I WANT HIT ANYONE THIS CAR WILL STALL OUT ON ME WITHOUT ANY WARNING. THERE HAS BEEN NO ACTION TAKEN FROM THE BANK OR THE DEALERSHIP ON HOW WE CAN FIX THIS PROBLEM THEY HAVE ALL BEEN IGNORING AND NOT RESPONDING TO MY CALLS TEXTS OR ANYTHING.

MULTIPLE TIMES THE VEHICLE HAS STALLED RANDOMLY WHILE BEING DRIVEN. THIS HAS HAPPENED SO MANY TIMES I'VE LOST COUNT (AT LEAST 20). THIS HAPPENS AT VARIOUS SPEEDS (FROM 0 MPH TO 70 MPH). THE ENTIRE ELECTRICAL SYSTEM SHUTS DOWN WHEN THE VEHICLE STALLS CAUSING THE STEERING AND BRAKES TO BE LESS EFFECTIVE. THIS COULD EASILY RESULT IN AN ACCIDENT. THE VEHICLE HAS BEEN TAKEN TO 2 DIFFERENT BUICK DEALERS FOR DIAGNOSTIC AND REPAIR. THE DEALERSHIPS HAVE NOT BEEN ABLE TO FIX THE PROBLEM. THE IGNITION SWITCH AND THE IGNITION RELAY HAVE BOTH BEEN REPLACED AND ALL THE ELECTRICAL CONTACTS HAVE BEEN CLEANED AND CHECKED. THESE REPAIRS HAVE NOT FIXED THE VEHICLE. I'VE CALLED BUICK CUSTOMER SERVICE AND THEY REFUSE TO DO ANYTHING FURTHER WITHOUT ADDITIONAL CHARGE TO THE OWNER. THE OWNER WILL NOT BE MAKING FURTHER REPAIRS. *TR

THIS IS THE THIRD TIME THAT THIS VERY SCARY AND LIFE THREATENING EVENT HAS OCCURRED. THE FIRST TIME THIS OCCURRED IN 2009 IN MINNESOTA. I PARKED IN A PARKING LOT. THE KEY WAS STUCK IN THE IGNITION. THIS WAS REPLACED AT A BUICK DEALERSHIP IN ROCHESTER, MN VIKING BUICK. THE SECOND TIME, IN JULY 2013 ON A MAJOR HIGHWAY IN CHICAGO GOING AT APPROXIMATELY 10 MPH GOING IN SLOW MOVING TRAFFIC. THE SAME EVENT OCCURRED FOR THE THIRD TIME ON JULY 19 ,2014. THE CAR STOPPED RUNNING WHILE DRIVING IN 2013 AND 2014. THE ENGINE TURNED OFF. THE STEERING WHEEL DID NOT MOVE. I ATTEMPTED TO RESTART THE CAR SEVERAL TIMES. THE KEY DID NOT MOVE NOR COULD IT BE RETRIEVED. THE BATTERY LIGHT THEN TURNED ON. AFTER SEVERAL MINUTES, I WAS ABLE TO RESTART THE CAR BY TURNING THE IGNITION KEY. I WAS NOT AWARE THAT THERE WERE RECALLS ON BUICK RENDEZVOUS 2004. I LEARNED ABOUT THESE FROM LISTENING TO THE NEWS. I HAVE CALLED BUICK IN JUNE 2014. I WAS TOLD THAT BASED ON MY VIN, THE CAR DOES NOT QUALIFY FOR A RECALL AND THEY REFUSED TO HELP ME WITH EVALUATING THE CAR. I HAVE TOLD THEM THAT THE IGNITION SYSTEM HAS BEEN REPLACED IN 2009. BUICK TELLS ME THAT THEY DO NOT SEE THIS ON THEIR SYSTEM. I HAVE THE RECEIPTS, PAYMENTS AND INFORMATION FROM THE BUICK DEALERSHIP THAT COMPLETED THIS AS WELL AS FROM THE TOWING COMPANY THAT TOWED THE CAR THERE.THIS EVENT OCCURRED AGAIN ON JULY 19, 2014 WHILE I WAS IN A SHOPPING MALL PARKING. AN ADDITIONAL EVENT THAT I NOTICED THIS THIRD TIME WAS THAT I COULD NOT EVEN GET OUT OF THE CAR AS IT REMAINED UNLOCKED. I HAVE REVIEWED ON YOUR WEBSITE THAT THERE HAVE BEEN SEVERAL RECALLS RELATED TO THESE EVENTS AND OTHERS FOR WHICH I HAVE NOT BEEN NOTIFIED BY GM OR BUICK. I HAVE HAD THE CAR GO THROUGH DIAGNOSTICS SEVERAL TIMES THROUGHOUT THE YEARS, BUT WHAT HAS HAPPENED IS NOT IDENTIFIED AT THE CHECK UPS. *TR

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.
