GM, THE MANUFACTURER CAME AND INSPECTED THE TRUCK. GM WOULD NOT ALLOW THE TRUCK TO BE FIXED BY THE DEALERSHIP UNTIL THEY INSPECTED IT. THE DEALERSHIPS REPORT STATED THAT THEY REPLACED THE RIGHT FRONT HUB BEARING AFTER TESTING AND THE FOUND BEARING CAUSED UNWANTED ABS OPERATION DURING SLOW SPEEDS.

VIBRATION OF ENTIRE VEHICLE AT HIGHWAY SPEEDS FROM DAY ONE. *AK

TO THOSE THAT COULD HELP ME GET GMC OR RANDY REED GMC PONTIAC IN KANSAS CITY, MO TO FIX THIS VIBRATION.I HAVE HAD THIS VIBRATION IN THE TRUCK SINCE I DROVE IT OFF THE LOT WHEN IT WAS BRAND NEW AT 6 MILES WITH A DELIVER MILES OF 23. I HAVE TAKEN IT BACK TO THE DEALER 13 TIMES IN THE LAST 14 MONTHS AND 8 OUT OF THOSE 13 TIMES IT WAS FOR THE VIBRATION. THE DEALER HAD PUT ALL NEW TIRES ON THE TRUCK AFTER ABOUT 3,000 MILES BUT STILL COULD NOT GET THE VIBRATION ALL THE WAY OUT. IT WAS TO A POINT WHERE I COULD STAND IT BUT I WAS NOT HAPPY WITH IT. THE VIBRATION COMES ON BETWEEN 65 TO 70 MPH WHICH INDICATES THE TIRES. THE TIRES ARE GOODYEAR WRANGLER ST P235/75R16 OWL WHICH IS THE ORIGINAL OEM TIRE FOR THAT TRUCK ON THAT YEAR. DURING THE TESTING AROUND THE TIME OF EXCHANGING OF ALL THE GOODYEAR WRANGLER ST FOR EXACT SAME THING WE PUT A SET OF FIRESTONE WRANGLER HT I BELIEVE ON IT AND IT RODE PERFECTLY SMOOTH. ON 08/15/2000 I TOOK MY TRUCK IN FOR A BULLETIN THE SERVICE MANAGER WANTED TO DO TO IT TO STRENGTHEN THE FRONT END ON IT AND I GOT IT BACK TWO DAYS LATER AND IT RIDES ROUGHER THAN BEFORE. I TOOK IT BACK ON 08/29/2000 AND THE NEW SERVICE MANAGER GOT INVOLVED AND SAID HE COULDNT FEEL ANYTHING ON VIBRATION SO I TOOK HIM FOR A RIDE AND WHEN YOU GO UP OR DOWN A HILL WITH THE CRUISE CONTROL ON AT 65 OR 67 MPH YOU FEEL THE VIBRATION IN THE FLOOR SEAT AND STEERING WHEEL ALSO THE MIRRORS VIBRATE SOMETIMES WHERE YOU CAN NOT MAKE OUT THE VEHICLE LIGHTS BEHIND YOU. THEN THE SERVICE MANAGER SAID IT STILL RIDES SMOOTHER THAN MY NEW DEMO WITH LESS THAN 600 MILES ON IT. I BELIEVE HE HAS THOSE FIRESTONE WRANGLER SOMETHING ON THE DEMO. I ALSO TALKED TO GMC A FEW TIMES AND THEY ARE TO THE POINT THERE IS NOTHING THEY WILL DO.I LIKE THE TRUCK BUT HATE THE VIBRATION AND IT IS VERY FRUSTRATING ON TRIPS.THE TRANSMISSION ALSO DOWNSHIFTS WHEN YOU GO OVER A HILL WITH IT SET ON 60MPH AND AIR CONDITIONING RUNNING.THEY WOULDN'T EVEN LIST THIS COMPLAINT WHEN I TOLD THEM ABOUT IT.

AFTER SERVICE DEPARTMENT REPLACED SEVERAL COMPONENTS IN THE FRONT END OF MY 1999 GMC SIERRA SLE XCAB 2WD SHORT BOX IT NOW PULLS TO THE LEFT ON FLAT HIGHWAY WHERE AS IT PULLED TO THE RIGHT BEFORE THE PARTS WHERE INSTALLED. IF THERE IS RUTS FROM WEAR IN THE HIGHWAY THEN IT WILL MAINTAIN OR TRACK THEM. I EXPLAINED TO THE SERVICE MANAGER THAT A 300 POUND PERSON WILL PULL THE FRONT END ALIGNMENT APPROXIMATELY 1 DEGREE SO IT HAS TO BE RIGHT ON AND HE SAID IT WAS. WELL IT STILL PULLS TO THE LEFT AFTER THEY REPLACED ALL THE PARTS IN THE FRONT END ON THERE BULLENTIN FOR THE VIBRATION PROBLEM. THE SERVICE MANAGER TELLS ME THERE IS NOTHING MORE THEY CAN DO FOR ME.( DOT NUMBER: M63D TIRE SIZE: P235/75R16 )

MAJOR VIBRATION AT SPEEDS OVER 60, ALSO ANTILOCK BRAKE FAILURE OR JUMPING --DEALER WAS VERY RECEPTIVE AND STILL IS BUT GM SEEMS TO BE IGNORING THIS PROBLEM. *AK

I HAVE EXPERIENCED EXCESSIVE WEARING OF THE FRONT BRAKES, WHICH HAS RESULTED IN THE ROTORS BEING REPLACED FIRST, THEN THE PADS REPLACED 2 WEEKS LATER, AND UPON REPLACING THE PADS THE NEW ROTORS REQUIRED RESURFACING. SINCE THEN AFTER DRIVING APPROX 5K MILES, I WAS TOLD THAT THE NEW PADS ARE APPOX 40% WORN. I REQUIRED THE RIGHT FRONT BALLJOINT TO BE REPLACED WHEN THE ROTORS WERE DONE. WHEN APPLYING THE BRAKES & HITTING A BUMP IN THE ROAD, THE BRAKE PEDAL GOES DOWN TO THE FLOOR AND HAS A COMPLETE LOSE OF BRAKING. IT FAILED THE ANNUAL INSPECTION, DUE TO A LEAKING DONNUT GASKET. THE TAILGATE SQUEAKS & RATTLES, AND APPEARS OUT OF ALIGNMENT. THE FRONT DRIVER'S DOOR CREAKS REQUIRING REPEATED GREASING. THERE APPEARS TO BE EXCESSIVE WEARING IN THE FRONT END AND BRAKING SYSTEM, AS WELL AS EXCESSIVE CREAKING & NOISE FROM THE REAR AREA OF THE TRUCK, TAILGATE, AND DRIVER'S DOOR. I HAVE BEEN MET WITH CONTINUED RESISTANCE AND LACK OF ANSWERS FROM BOTH THE MFG AND DEALER. ANY HELP OR INFORMATION WOULD BE APPRECIATED.*AK

THERE IS A RATTLE UNDERNEATH THE REAR OF THE VEHICLE, THE DEALER HAS TRIED TO REMEDY THE PROBLEM BY THE FOLLOWING: CHANGED THE POWER STEERING AND TRANSFER CASE FLUID, REPLACED THE SHOCK ABSORBERS, THE SPARE TIRE JACK HOIST, AND HOSES, HOWEVER THE PROBLEM STILL EXISTS. *SLC

ABS BRAKES FAIL WHEN YOU APPLY BRAKES WHEN THERE IS A BUMP IN THE ROAD. I HAVE HAD 14 FAILURES IN 2095 MILES. THE BRAKE PEDAL DROPS DOWN SLIGHTLY AND BECOMES SOLID, YOU CAN NOT PUSH DOWN ANYMORE AND THE VEHICLE GLIDES TO A SLOW STOP. IT WILL NOT STOP IN AN EMERGENCY IN THIS CASE. THE PROBLEM SEEMS TO BE IN THE SUSPENSION AND THE ABS BRAKES. THE VEHICLE VIBRATES AND DOES NOT RECOVER FAST WHEN YOU GO OVER A SLIGHT BUMP IN THE ROAD. AT HIGHWAY SPEED THE WHOLE VEHICLE AND STEERING WHEEL VIBRATES. THE PLASTIC HUB NUTS ALWAYS COME LOOSE WHEN DRIVING.*AK

ENTIRE VEHICLE VIBRATES/SHAKES EXCESSIVELLY AT HIGHWAY SPEEDS (60-75 MPH), ON CERTAIN STRECHES OF ROAD.

ON MULTIPLE OCCASIONS THE TRUCK AFTER TRAVELING 6 TO 10 MILES AT 70+ MILES PER HOUR WOULD START TO VIOLENTLY SHAKE AND IT WOULD NOT STOP UNTIL YOU CAME TO A COMPLETE STOP. IT STARTED OUT DOING IT ONCE A WEEK BUT GOT PROGRESSIVELY WORSE UNTIL IT WAS DOING IT EVERY DAY. IT HAS BEEN TO THE DEALER ON 8/5/99, THEN AGAIN THE WEEK OF 8/23 THROUGH 8/27/99, AND RETURNED AGAIN 9/14/99, THEY CALLED ME BACK THEY COULD NOT GET IT TO DUPLICATE THE PROBLEM.

THE TRUCK IS STILL AT THE DEALERSHIP AS OF 10/27/99 AND I THINK IT NEEDS TO BE FILED AS A LEMON UNDER THE NC GENERAL STATUTE 20-351, SO THAT NO ONE ELSE ENDS UP WITH IT OR GETS HURT OR KILLED IN AN ACCIDENT.
