WHY DOES GMC NOT DO A TOTAL RECALL ON THE VEHICLE THEY SALE AND THEY PICK THE STATES WHERE THEY WANT THE RECALL TO TAKE PLACE. IN UTAH WE USE SALT ON THE ROADS AND YES WE DO GET SNOW REMEMBER THE WINTER OLYMPICS OF 2002 THIS IS NOT RIGHT FOR THEM TO PICK AND CHOOSE STATES.

MY 2000 CHEVROLET SILVERADO K2500 , VIN [XXX], PURCHASED IN DECEMBER 1999, HAD A HYDRAULIC POWER, LOSS RESULTING IN IMMEDIATE LOSS OF POWER STEERING AND BRAKES. I WAS ABLE TO SECURE THE VECHICLE AND CALL A TOW TRUCK AND TOWED TO DELERSHIP. NHTSA HAS A RECALL 05V-005000 FOR THIS MODEL AND YEAR, HOWEVER IT DOES NOT COVER MY VIN. CONTACTED GM TO SEE IF THEY WOULD REPAIR THIS UNDER THE RECALL AND THEY REFUSED. IT APPEARS THERE ARE MORE VECHICLES WITH FAULTY POWER STEERING PUMPS THAN THE RECALL COVERS. REQUEST YOU REVIEW THIS RECALL. THE PUMP WILL BE REPLACED AND I WILL REQUEST THE REMOVED PARTS BE SAVED FOR ME. *AK *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I HAVE A 2000 CHEVROLET, SILVERADO 2500 PICKUP TRUCK I BOUGHT NEW. WITH ABOUT 125,000 MILES . 2 MONTHS AGO I STARTED HAVING A PROBLEM. WHEN COMING TO A COMPLETE STOP THE BRAKES GO TO THE FLOOR, MAKE A HORRIBLE NOISE AND THEN THE TRUCK THRUSTS FORWARD. THE PAST TWO MONTHS THIS PROBLEM HAS BEEN VERY SPORATIC. AS FEW AS 3 TIMES A WEEK AS MUCH AS 10 TIMES A WEEK. ONE TIME I WAS STOPPING AT A SIDE ROAD WAITING TO ENTER A HIGWAY AND THE TRUCK STOPPED THEN THRUST FORWARD INTO THE TRAFFIC. FORTUNATELY I DID NOT GET HIT BUT CAME CLOSE TO A ACCIDENT. THE WAY TO STOP IT IS BY THROWING IT INTO PARK. YESTERDAY I STOPPED IN FRONT OF A CUSTOMERS GARAGE AND WENT THROUGH THE GARAGE DOOR AS THE TRUCK THRUST FORWARD. I CONTACTED THE CHEVY DEALER AND HAD THE MASTER CYLINDER REPLACED. NO GOOD. THEN WAS TOLD IT WAS THE POWER BOOSTER. NOT THAT. .TODAY THEY SAY IT IS THE SENSOR IN ONE OF THE WHEELS. WILL REPLACE TOMORROW.I DO NOT UNDERSTAND HOW THAT WILL STOP IT FROM THRUSTING FORWARD. I HAVE SPEND MUCH MONEY SENSOR ALONE COSTING 600.00 AND THE GARAGE DOOR 760.00 MY BIGGEST WORRY IS FEAR OF THRUSTING FORWARD WHEN AT A CROSS ROAD. THE CAR DEALERS AND GENERAL MOTORS HOT LINE SAID THEIR IS NO PRIOR REPORT . I HOPE ITS THE SENSORBECAUSE EVERYTIME THIS HAPPENS YOU PANIC . IT IS VERY COSTLY AND COULD COST ME MY LIFE. I ALSO THINK THAT MORE CONCERN FROM THE MANUFACTURER COULD BE TAKEN . I DO NOT KNOW WHAT TO DO IF THIS SENSOR DOES NOT WORK AS THEY SAY THIS IS THE ONLY CODE THAT CAME UP WHEN PUT ON A MACHINE. THEY PUT IT ON THE MACHINE BECAUSE SOMETIMES THE ABS LIGHT COMES ON AND I HAD TO GET IT TO THE DEALER WHEN IT WAS ON AS THEY COULD NOT CHECK IT UNLESS IT WAS ON. THIS WAS DIFFICULT AS THE DEALER IS 30 MINUTES AWAY. IF YOU HAVE EVERY HEARD OF THIS PROBLEM BEFORE I HAVE TO SPEND MORE UNNECESSARY MONIES OR BEFORE I GET HURT. I WOULD APPRECIATE ANY INFORMATION YOU COULD GIVE ME. THANKS RICH . *AK

MY SON REAR ENDED A SEMI-TRACTOR TRAILER TRUCK IN A SNOW STORM LAST WEEK. HE WAS WEARING HIS SEAT BELT. AIR TEMPS PREVIOUS WEEK WERE IN THE -20 TO -40 RANGE. TEMPERATURE AT TIME OF ACCIDENT WAS -15. I RAISE THIS AS INDICATED BELOW. *AK MY CONCERNS ARE: 1. THE AIR BAG DID NOT DEPLOY. THERE WAS $6000 DAMAGE TO OUR 2004 CHEVY K2500 CREW CAB PICK-UP TO INCLUDE GRILL, RADIATOR, BOTH QUARTER PANELS, HOOD, BUMPER AND FORWARD ENGINE COMPONENTS. THE IMPACT SPEED WAS ESTIMATED AT 25 MPH. THAT SHOULD HAVE DEPLOYED THE BAG. I REALIZE THAT THERE WERE NO INJURIES AND MY INSURANCE WOULD HAVE COVERED THE BAG, BUT I THINK (AS DID EVERYONE ELSE WHO HAVE SEEN THE DAMAGE) THAT THE BAG SHOULD HAVE DEPLOYED. 2. ABS SYSTEM FAILED. TRUCK REAR END SLID TO RIGHT TOWARD TRAFFIC. MY SON WAS ABLE TO REGAIN CONTROL. CHOICE OF IMPACT WAS EITHER INTO ON COMING TRAFFIC, OFF ROAD DOWN DEEP HILL INTO FOREST OR REAR END TRUCK. NOTE: OTHER OWNERS IN AREA OF THE 1999-2000 PICK-UP SERIES HAVE ALSO HAD ABS SYSTEM FAILED. LOCAL DEALERS ARE AWARE OF FAILURE AROUND 100,000 MILE MARK BUT SAY THAT IT IS NORMAL. ABS LIGHT IS NOW ON. SIDE NOTE - WE HAVE HAD REPEATED PROBLEMS WITH THIS VEHICLE AND HAVE TAKEN IT TO DIFFERENT DEALERS. PROBLEMS INCLUDE ONGOING SHORT IN ELECTRICAL SYSTEM IN COLD WEATHER, 4 WHEEL DRIVE FAILS TO DISENGAGE ALTHOUGH LIGHT ON DASH SAYS IT HAS (DISCOVERED AT LOCAL REPAIR SHOP), COMPUTER FAILURE ON DEALER INSTALLED EQUIPMENT (NOT COVERED UNDER WARRANTY BECAUSE IT WAS AN OPTION).
2000 K2500 PICKUP. HAVE HAD THE BRAKES AND ROTORS REPLACED TWICE AND NOW NEEDS A 3RD TIME. TRUCK ONLY HAS 40,000 MILES AND CAN NOT KEEP BRAKES AND ROTORS ON IT. THE SECOND TIME THE DEALER FINALLY TOLD ME GM HAD A PROBLEM WITH THESE BRAKE ISSUES AND NOW ARE GIVING ME THE RUN AROUND TO GET THE BRAKES DONE THE 3RD TIME. *JB
WHEN THE DRIVER ATTEMPTED TO STOP THE VEHICLE THE BRAKES FAILED AND THE DRIVER HAD TO USE THE EMERGENCY BRAKE TO SLOW THE VEHICLE. WHEN THE DRIVER TURNED IN A DRIVEWAY HE SAW SMOKE EMITTING FROM HE ENGINE COMPARTMENT. THE FIRE DEPARTMENT ARRIVED AND EXTINGUISHED THE FIRE. THE VEHICLE WAS A TOTAL LOSS. *PH *NLM
WHILE IN MOTION, CONSUMER WAS MAKING A A LEFT TURN WHEN THE A POPPING SOUND WAS HEARD AND IMMEDIATELY THE STEERING WENT OUT. CONSUMER TRIED TO APPLY THE BRAKES BUT NOTHING HAPPENED. VEHICLE WAS TAKEN TO THE CHEVY GARAGE AND THE VACUUM PUMP HAD TO BE REPLACED. *JG *DT
