NHTSA Complaint #10170723 — 2002 BUICK RENDEZVOUS

THREE SAFETY RELATED ISSUES WITH MY 2002 BUICK RENDEZVOUS CXL. THE ABS SENSORS FAILED WHICH WAS A DIFFICULT PROBLEM TO DIAGNOSE AS THE PROBLEM WAS ACTUALLY CAUSED BY WATER IN THE INSULATION TO THE SENSOR WIRING HARNESSES. I'M NOW BEING NOTIFIED OF A FRONT WHEEL BEARING PROBLEM THAT HAS NOT YET REACHED A FORMAL RECALL. SECOND ISSUE INVOLVES THE AWD REAR AXLE ASSEMBLY (DIFFERENTIAL). MOANING NOISES START IN THE REAR END, IN LOW SPEED TURNS SUCH AS PARKING LOT MANEUVERS. OCCURRENCE INCREASES IN SEVERITY AND FREQUENCY FAIRLY QUICKLY. THE REAR AXLE IS TO BE REPLACED BY THE DEALER UNDER MY EXTENDED WARRANTY. BUT I NOTICE THAT THIS IS NOT A RANDOM OR UNUSUAL PROBLEM WITH THIS YEAR/MODEL BUICK. I WOULD THINK THAT BOTH OF THESE ISSUES DUE TO THEIR RATE OF OCCURRENCE WOULD TRIGGER A FORMAL RECALL. WHY DOES THE REAR DRIVE AXLE CONTINUE TO FAIL? IF IT SHOULD FAIL CATASTROPHICALLY, WILL IT POSE A SAFETY ISSUE, ESPECIALLY IF HIGHWAY SPEEDS ARE INVOLVED AND THE VEHICLE BECOMES UNSTABLE? *NM
