I'VE HAD SEVERAL PROBLEMS WITH THE TRUCK SINCE I BOUGHT IT 3 MONTHS AGO. I'VE FIXED ALMOST ALL OF THEM-ABS WAS ACTIVATING WHICH WAS PUSHING ME INTO TRAFFIC NEARLY CAUSING A WRECK SO I CHANGED THE ABS SPEED SENSOR AND HUB ASSEMBLY. FRONT SUSPENSION WAS GONE SO I REPLACED THAT; AS WELL AS STEERING PARTS, BRAKES, THE PARKING BRAKE DOESN'T WORK, FIXING IT NEXT. OIL SENDING UNIT, A/C BELT AND REFRIGERANT REPLACED. THE PROBLEMS LEFT ARE EVAP EMISSION VENT VALVE SOLENOID, THROTTLE PEDAL POSITION SENSOR, AND RANDOM/ MULTIPLE CYLINDER MISFIRE SOMETIMES AND CYLINDER 4 MISFIRE OTHER TIMES. IN 4X4 WHEN IT GETS UNDER A LOAD SOMETHING SOUNDS LIKE IT'S BINDING UP AND IT POPS BUT IT STILL WORKS. WHEN I SHIFT INTO DRIVE OR REVERSE OR ACCELERATE FROM A STOP IT HAS A SHIFT FEELING IN THE REAR WITH A THUMP SOUND. SOMETIMES I CAN PUSH THE GAS AND IT WON'T DOWNSHIFT TO SPEED UP WHEN I'M ON THE HWY BUT THAT'S PROBABLY THE TPPS. I JUST WANT MY 4X4 WORKING AND MY SHIFT THUMP FROM A STOP TO GO AWAY. HELP. IN 4X4 THE NOISE HAPPENS IN FWD REVERSE AND WHEN TURNING AND WORSE IN 4LO BUT HAPPENS IN 4HI AND AUTO BUT NOT IN 2HI. *TR

I PURCHASED THIS TRUCK USED AND WAS ABLE TO USE FOR A BOUT A MONTH BEFORE BOTH REAR SPRING PERCHES BROKE ALLOWING THE SPRINGS TO REST UNDER THE PICKUP BODY, AFTER REPLACING THEM THE BRAKE LINES RUPTURED BECAUSE OF RUST ANOTHER POOR QUALITY PRODUCT FROM GM !

I OWN A 2000 GMC SIERRA 2500 4WD. I BOUGHT THIS TRUCK NEW IN JUNE OF 2000. IN THE PAST YEAR, THE CORROSION ISSUES ARE BECOMING OVERWHELMING. YESTERDAY, A BRAKE LINE BLEW OUT WHILE DRIVING. THE BRAKE PEDAL WENT TO THE FLOOR AS I APPROACHED A STOP SIGN AT AN INTERSECTION WITH A STATE HIGHWAY. LUCKILY, I GOT STOPPED AS I WAS ONLY GOING 25 MPH. I BABIED IT TO A LOCAL GARAGE 1/4 MILE AWAY, AND FOUND BRAKE FLUID DRIPPING OUT BELOW THE FUEL TANK AREA. AFTER LOOKING UNDERNEATH, THE MECHANIC NOTICED THAT MOST OF THE BRAKE LINES WILL NEED REPLACED BECAUSE OF RUST. GOES ALONG WITH THE CORROSION ISSUE UNDER THE WHOLE TRUCK. I'VE ALREADY REPLACED THE REAR SPRING SHACKLES ON BOTH SIDES, AS ONE HAD RUSTED AND BROKE IN HALF WHILE DRIVING. THIS CAUSED THE LEAF SPRING TO SLAM UP AGAINST UNDERSIDE OF THE BED, WHICH DENTED AND CRACKED THE PAINT IN THE BED. I RESTORE VEHICLES FOR A LIVING, AND I'VE SEEN CARS FROM THE 1940'S THAT DON'T HAVE THIS MUCH RUST ON THE UNDERSIDE. COME ON GM!! IT'S GREAT THAT THE BODY LOOKS LIKE NEW AND THE ENGINE RUNS GREAT, BUT IT DOESN'T DO ANY GOOD WHEN THE FRAME ROTS OUT FROM UNDERNEATH!! AND NOW THE BRAKE LINES---GLAD I WASN'T GOING 60 MPH WITH A LOADED TRAILER WHEN IT BLEW!! *JB

THE FRAME ON THE TRUCK IS CRACKED SEVERAL INCHES IN A COUPLE OF PLACES AND ROTTED. IT IS VERY THIN AND I WAS TOLD THERE WAS NOTHING SOLID TO WELD TO AND REPAIR IT. THEY SAID I WOULD HAVE TO HAVE THE FRAME REPLACED. THE TRUCK HAS JUST TURNED 100000 MILES. I HAVE HAD IT FOR SIX YEARS AND TAKE EXCELLENT CARE OF IT. IT RUNS GREAT. THE BODY IS IN EXCELLENT SHAPE, THERE IS ONE SMALL HOLE IN THE DRIVER SIDE ROCKER PANEL I WAS GOING TO REPAIR IN THE NEAR FUTURE ( I DO NOT KNOW IF I WILL NOW BOTHER). OTHER THAN THAT THE BODY IS NEAR PERFECT. THERE IS NO ROT IN THE FLOORS OR TRUCK BED. THE REPAIR SHOP COULD NOT BELIEVE HOW BAD THE FRAME IS WHEN THE TRUCK LOOKS SO GREAT. I HAVE FOUND A NUMBER OF COMPLAINTS ON THE INTERNET SIMILAR TO THIS, MAYBE IF ENOUGH PEOPLE SPEAK UP SOMETHING WILL GET DONE. ALSO, THE ANTI LOCK BRAKES HAVE NOT WORKED FOR SOME TIME NOW. I WAS TOLD THEY GET RUST IN THE ASSEMBLY AND DO NOT WORK RIGHT. I HAVE ALSO HAD SEVERAL BRAKE LINES BREAK AND NEED TO BE REPLACED. I REALIZE THAT BRAKE LINES DO RUST OVER TIME AND DO NEED TO BE REPLACED (THEY SHOULD BE MADE FROM STAINLESS STEEL FROM THE FACTORY) BUT THE ANTI LOCKS SHOULD WORK AND A FRAME SHOULD NOT ROT AND CRACK AS IT HAS. *TR

I EXPERIENCED SUDDEN BRAKE FAILURE IN MY DRIVEWAY. THERE WAS NO WARNING LIGHT,JUST THE BRAKE PEDAL GOING TO THE FLOOR. MY MECHANIC LOOKED AT THE FAILED LINE AND SAID ALL MY LINES AND ABS UNIT WERE CORRODED AND NEEDED TO BE REPLACED. HE ALSO FOUND MY RIGHT REAR SPRING HANGER WAS RUSTED OFF AND THE SPRING WAS JUST RESTING ON THE BODY. THE REAR WHEEL BRAKE BACKERS PLATES ARE RUSTED OFF ALSO, AND THE ENTIRE FRAME IS VERY CORRODED. THIS IS A HUGE REPAIR BILL THAT MAY EXCEED THE VALUE OF THE TRUCK. THIS IS NOT NORMAL CORROSION. I HAVE LIVED IN NH 55 YRS AND HAVE NEVER HAD A VEHICLE ROT LIKE THIS. I HAVE A 2000 VOLVO V70 WITH 147,000 MILES ON IT WITH NO ISSUES. OBVIOUSLY GM CHEAPENED THIS TRUCK UP OR BOUGHT DEFECTIVE PARTS. I HAVE FOUND HUNDREDS OF ACCOUNTS ON THE INTERNET IDENTICAL TO MINE. THIS VEHICLE NEEDS TO BE RECALLED BEFORE PEOPLE ARE KILLED. I AM THANKFUL I WAS IN MY DRIVEWAY AND NOT HIGHWAY OR CITY DRIVING AT THE TIME OF THE FAILURE. DO THE RIGHT THING AND HOLD GM RESPONSIBLE. THERE WOULD BE NO GM WITHOUT OUR TAX DOLLARS AND THEY NEED TO MAKE THIS RIGHT. THANK YOU *TR

WHILE TRYING TO SELL MY VEHICLE, AN AUTO SERVICE FACILITY DISCOVERED SERIOUS FRAME CORROSION WHICH COULD PROVE TO BE A SAFETY ISSUE. THE CORROSION SEEMS EXCESSIVE AND SUGGESTS DESIGN AND/OR MATERIAL DEFICIENCIES. I HAVE HAD TO REPLACE ALL BRAKE LINES AND HAVE HAD TRANSMISSION SHIFT LINKAGE FAILURE, ALL DUE TO RUST. ALSO, EXCESSIVE BODY RUST IN THE LOWER ROCKER PANELS HAS OCCURRED, MORE OF A COSMETIC PROBLEM, BUT INDICATIVE OF THE PERVASIVE RUST PROBLEM THAT EXISTS. *TR

RUST- HAD TO REPLACE ALL THE BRAKE LINES,ROCKER PANELS AND CAB CORNERS,GAS TANK STRAPS RUSTED OUT AND BROKE OFF .BOTH SPRING SHACKLES BROKE FROM RUST AND HAD TO BE REPLACED,THE FRAME HAD TO BE FIXED(CRACKED) AND NOW THE SHOCK MOUNTS HAVE RUSTED OFF AND HAVE TO BE FIXED AND ITS ONLY GOT 115,000 MILES. *TR

TL*THE CONTACT OWNS A 2000 GMC SIERRA 1500. THE CONTACT RECEIVED A RECALL NOTICE FOR THE SERVICE BRAKES WHEEL SPEED SENSOR. ON SEPTEMBER 19, 2007, THE DEALER REPAIRED THE RECALL; HOWEVER, THE ABS AND BRAKE WARNING LIGHTS HAVE BEEN ILLUMINATED SINCE THE RECALL REPAIR WAS PERFORMED. WHILE DRIVING BETWEEN 15 AND 50 MPH, THE VEHICLE MADE A LOUD NOISE. THE DEALER STATED THAT THE WHEEL SPEED SENSOR AND WHEEL BEARINGS WERE ONE UNIT. THE DEALER ALSO STATED THAT THEY CLEANED ONE SIDE AND THE OTHER SIDE DID NOT NEED TO BE CLEANED. THE SERVICE MANAGER CONFIRMED THAT THEY USED FORCE TO REMOVE PARTS FROM THE VEHICLE AND STATED THAT THE VEHICLE WAS ABLE TO WITHSTAND MUCH MORE DAMAGE THAN WHAT OCCURRED. DURING THE RECALL REPAIR, THE DEALER DAMAGED THE FRONT BALL JOINT AND DENTED THE ROTORS. THE DRIVER SIDE BALL JOINTS WERE REPLACED; HOWEVER, THE FAILURE IS WORSE THAN IT WAS PRIOR TO HAVING THE RECALL REPAIR PERFORMED. THE DEALER WAS UNABLE TO PROVIDE THE CONTACT WITH AN INVOICE. WHEN THE ABS LIGHT IS ILLUMINATED, THE BRAKES FAIL TO OPERATE NORMALLY. THE CONTACT HAS TO SHUT OFF THE ENGINE TO ALLOW THE ABS TO RESET ITSELF. A SECOND DIAGNOSIS BY A DIFFERENT DEALER REVEALED THAT THE DRIVER AND FRONT PASSENGER SIDE WHEEL BEARINGS WERE DAMAGED, INCLUDING THE PASSENGER SIDE THAT WAS REPAIRED FOR THE RECALL. THE SECOND DEALER FURTHER STATED THAT THE NOISE WAS DUE TO THE WHEEL BEARINGS FAILING TO MOVE FREELY. THE MANUFACTURER WAS INFORMED BY THE DEALER THAT THERE WAS NO NOISE PRESENT. THE MANUFACTURER PROVIDED THE CONTACT WITH CLAIM NUMBER 71558918083. THE APPROXIMATE FAILURE MILEAGE WAS 106,500 AND CURRENT MILEAGE WAS 108,500. UPDATED 03/05/08. *LJ THE CONSUMER STATED INFORMED DEALER MANY TIMES FOR THE TICKING HEARD IN THE VEHICLE SINCE THE VEHICLE AT THE TIME PURCHASE. UPDATED 03/04/08 *TR

DT: THE CONTACT HAD RECALL 05V37900 REPAIR WORK DONE ON THE ANTI LOCK BRAKES. APPROXIMATELY ONE MONTH LATER, WHILE APPLYING THE BRAKES, HE HEARD A LOUD GRINDING NOISE. THE CONSUMER WAS ONLY GOING 8-10 MPH AND THE CONSUMER TRAVELED 200-300 FEET BEFORE HE WAS ABLE TO COME TO A STOP. HE TOOK THE VEHICLE TO THE DEALERSHIP, AND THEY STATED THE WHEEL BEARINGS NEEDED TO BE REPLACED. *AK UPDATED 01/11/06. *JB

I PURCHASED MY VEHICLE USED. THE USED CAR LOT SAID ALL THE CLUNKING IN THE REAR AND VIBRATION IN THE FRONT WAS DUE TO AN ALUMINUM DRIVE SHAFT. I HAVE BEEN TO NUMEROUS NEW AUTO DEALERS AND NO ONE CAN FIND THE SOURCE. I HAVE PHONED GM AND THEY SAY IT IS THE FIRST TIME THEY EVER HEARD OF CLUNKING NOISE FROM THE REAR. YET THIS PROBLEM IS POSTED ALL OVER THE INTERNET. IT MAY NOT CAUSE A CRASH BUT IT SURE IS IRRITATING TO HEAR OVER EVERY LITTLE BUMP IN THE ROAD. *JB

I HAD THE DEALER DO A SCHEDULE TIRE ROTATION, AND ON THEY WAY HOME I REACHED THE SPEED OF 40 MPH THE TRUCK STARTED TO SHAKE LIKE I WAS GOING OVER SPEED BUMPERS. THIS STOPPED BUT THE FRONT END STILL BOUNCES WHEN EVER YOU GO OVER A SERIES OF SMALL BUMPS THE WHOLE FRONT JUST SHAKES YOU HAVE TO USE TWO HANDS TO KEEP THE VEHICLE IN CONTROL, DON'T USE THE BRAKE THE PEDAL GOES SOFT UNTIL YOU ARE OUT THE ROUGH ROAD. I HAVE HAD THE TIRES REPLACED AND BUT NEW RIMS ON THE VEHICLE. THE BOUNCE IS STILL NOTICEABLE AT SPEEDS OVER 40, THE ROAD DOES NOT CHANGE THE EFFECT. THE CROWNING OF THE ROAD IS NOT THE PROBLEM. THE DEALER SAYS THE FRONT IS TIGHT AND CAN NOT DUPLICATE MY PROBLEM SO THEY CAN NOT FIX IT. THE SERVICE MANGER SAYS I'VE LOWERED MY FRONT END THIS GMC SIERRA IS TOTALLY OEM EXC FOR TIRE, AND AFTERMARKET DRESS.I HAD THE TRUCK ALIGNED AND THE THRUST ANGLE WAS OFF SO MY SON-INLAW AND I DID A THRUST ALIGNMENT FIRST AND THE FRONT END ALIGNMENT. ALSO ONE OF THE UPPER CONTROL ARM BOLTS WAS SLIGHTLY LOOSE, YOU COULD SEE THE BROWN RUSTY POWDER AROUND THE BUSHING SO THIS WAS LOOSE FOR SOME TIME. I AM A DIESEL MECHANIC SO I KNOW THERE IS SOMETHING WRONG LOOSE, OR WORN OUT THAT NEEDS TO BE DONE TO CORRECT THE PROBLEM, THINGS DO WEAR OUT AND I DO NOT MIND PAYING FOR THINGS TO BE DONE CORRECTLY

REAR OF VEHICLE CLUNKS WHEN STOPPING AND UPON MOVING FORWARD FROM A STOP. THIRD DOOR USED TO ACCESS REAR OF VEHICLE DOES NOT LATCH DURING COLD WEATHER OF 20 DEGRESS OR LOWER. *AK

CONSUMER STATES WHILE BACKING OUT OF DRIVEWAY BRAKE PEDAL BECAME HARD. CONSUMER COULD NOT SLOW DOWN AND RESULTED IN AN ACCIDENT. MRTHE LEFT FRONT WHEEL BEARING WAS FOUND TO BE DEFECTIVE. THIS CONTAINED THE BRAKE MOTION SENSOR WHICH WAS ALL ONE UNIT, CAUSING THE BRAKE FAILURE. *JG

TL* THE CONTACT OWNS A 2000 GMC SIERRA 2500. WHILE DRIVING APPROXIMATELY 35 MPH, THE REAR OF THE VEHICLE SLIGHTLY LOWERED TOWARDS THE GROUND. THE VEHICLE WAS DRIVEN WITH CAUTION TO THE CONTACT'S RESIDENCE. THE CONTACT INSPECTED THE VEHICLE AND NOTICED THAT THAT THE DRIVER SIDE MAIN FRAME RAIL WAS FRACTURED IN THE CENTER. ADDITIONALLY, THE PASSENGER SIDE MAIN RAIL WAS PARTIALLY FRACTURED. THE FAILURE WAS BEYOND REPAIR. THE CONTACT MENTIONED THAT THE BRAKE LINE AND REAR CROSS MEMBER NEAR THE FUEL TANK WERE COMPLETELY CORRODED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 92,000.

BRAKES MALFUCTION; WHEN APPLYING BRAKES THEY DO NOT STOP VEHICLE PROPERLY, CAUSING EXTENDED STOPPING DISTANCE. ALSO, FRONT BEARINGS/ UNIVERSAL JOINT, AND REAR LEAF SPRING ASSEMBLY HAD TO BE REPLACED. DEALER / MANUFACTURER NOTIFIED . FEEL FREE TO PROVIDE ANY FURTHER DETAILS ON THIS MATTER. *AK

TRUCK IS 2000 EXT CAB LB 1/2 TON. ON CONCRETE FWYS, AT CERTAIN SPEEDS, THE TRUCK "BOUNCES" (NOT VIBRATES). THE FWY I HAPPEN TO DRIVE TO WORK ALWAYS CAUSES BOUNCING. I'VE CHANGED SHOCKS WITH NO IMPROVEMENT. ALL NEW GM LONGBED (2500, CHEVYS, ETC) ALL HAVE THE SAME PROBLEM. YOU CAN SEE US ALL DRIVE AT SPECIFIC SPEEDS TO AVOID "BOUNCING". THE DEALER SAYS I GOTTA LIVE WITH THIS. I SAY "WHY".*AK

WHILE PULLING A LOAD VEHICLE WILL VIBRATE AT 5 TO 20 MPH. WILL VIBRATE FOR A COUPLE OF SECONDS WHEN IT HAS THE RIGHT LOAD ON IT. NO SOLUTION HAS BEEN FOUND YET. *AK *ML

CONSUMER COULD FEEL A VERY BAD VIBRATION COMING FROM FRONT OF CAR. CONSUMER STATED IT GOT WORSE WHEN SLOWING DOWN. *AK

TRUCK VIBRATES ON ACCELERATION FROM STOP TO 20MPH. *AK
