1996 GMC Sonoma

TL*THE CONTACT OWNS A 1996 GMC SONOMA. WHILE APPLYING THE BRAKES AT 55 MPH, THE BRAKE PEDAL EXTENDED ALL THE WAY TO THE FLOOR. THE EMERGENCY BRAKE WAS APPLIED TO STOP THE VEHICLE. THE CONTACT WAS A MECHANIC AND HE REPLACED THE FRONT BRAKE LINE FOR THE PASSENGER SIDE WHEEL. THE FAILURE WAS CORRECTED TEMPORARILY. HOWEVER, TWENTY MILES LATER, THE FAILURE RECURRED WHILE DRIVING 30 MPH. THE BRAKE LINE FOR THE FRONT DRIVER SIDE WAS REPLACED. THE ROAD CONDITIONS WERE NORMAL DURING BOTH FAILURES. THE MANUFACTURER STATED THAT THE VIN WAS NOT INCLUDED IN NHTSA RECALL NUMBER 97V146001 (SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS). THE CURRENT MILEAGE WAS 105,000 AND FAILURE MILEAGE WAS 104,980.

DT*: THE CONTACT STATED WHILE DRIVING 40 MPH UNDER NORMAL BRAKING ON WET ROADS, THE ABS LIGHTS ILLUMINATED AND THE VEHICLE HAD AN EXTENDED STOPPING DISTANCE. THE DEALER EXAMINED THE VEHICLE AND DETERMINED THE THREE SENSORS HAD TO BE REPLACED, BUT WERE NOT CERTAIN THAT THE REPLACEMENT WOULD CORRECT THE PROBLEM. THE VEHICLE WAS CURRENTLY AT THE DEALER FOR FURTHER REPAIRS. THE CONTACT ENCOUNTERED NHTSA RECALL # 99I006000 REGARDING THE SERVICE BRAKES, HYDRAULIC: ANTILOCK.

IN SNOWEY OR RAINEY WEATHER, ANTILOCK BRAKES PULSATE IRRADICALLY AT VARIOUS SPEEDS (INCLUDING 5 MPH) WHEN BRAKES ARE APPLIED, EVEN WHEN NO SKID OR HARD BREAKING IS OCCURING. BRAKING WHEN THIS OCCURS, WHICH IS INTERMITTENTLY, IS POOR AND UNEVEN. DEALER AND GM CORP. CONTACTED, BUT ALL SAY NO RECALLS HAVE BEEN INITIATED. THIS IS A DANGEROUS CONDITION, AND AN ACCIDENT (LAW SUIT) WAITING TO HAPPEN. *AK

THIS IS AN UPDATE TO A PREVIOUSLY SUBMITTED REPORT FOR ABS FAILURE ON THIS VEHICLE. THE INCIDENT DATE ON THIS REPORT IS APPROXIMATE. THE TWO WIRES TO THE RIGHT FRONT ABS SENSOR WERE SEVERED BY INTERFERENCE WITH THE UPPER CONTROL ARM AND THE DISK BRAKE BACK PLATE/SPLASH SHIELD, TO WHICH THE WIRING IS ATTACHED WITH RIVETED METAL CLIPS. IT APPEARS THAT THE WIRES BECAME TRAPPED BETWEEN THE UPPER CONTROL ARM STAMPING AND THE HUB AND/OR DISK BRAKE BACK PLATE/SPLASH SHIELD, POSSIBLY DURING TURNS THAT CYCLED THE FRONT SUSPENSION. THE WIRING INSULATION IS WORN IN SEVERAL LOCATIONS OTHER THAN THE BREAK POINT, AND THE FIRST METAL CLIP HAS BEEN TORN OFF THE POP RIVET THAT HOLDS IT TO THE BACKPLATE/SPLASH SHIELD. THIS IS THE SECOND TIME THIS WIRING HAS FAILED DUE TO THIS DESIGN OR INSTALLATION DEFECT. THE FIRST FAILURE WAS REPAIRED UNDER WARRANTY. NO REPAIRS HAVE BEEN PERFORMED AT THIS TIME AS WE HAVE BEEN WAITING FOR RECALL INFORMATION FROM GM, WHICH ARRIVED RECENTLY, BUT IT ADDRESSED AN ABS PROGRAMMING PROBLEM THAT AFFECTED BRAKING ON SURFACES THAT TRANSITIONED FROM WET TO DRY AND BACK. *AK

WE HAVE HAD NUMEROUS PROBLEMS WITH THIS VEHICLE SINE ONE MONTH AFTER PURCHASE INCLUDING THE IDLE STICKING/INTERIOR MOULDING CRACKING/TRANSMISSION REBUILT/COMPUTER REPLACED DUE TO FAILURE ENGINE CHECK LIGHT INDICATOR LIGHT DOES NOT TURN OFF, AND RIGHT SIDE BRAKE DOES NOT SEEM TO WEAR PROPERLY.. MY HUSBAND IS ABLE TO RECALL MORE. *AK
