LATE ON JULY 30, I HAD A SINGLE VEHICLE ACCIDENT. I WAS DRIVING DOWN THE INTERSTATE / TOLL ROAD ON THE WAY BACK FROM THE AIRPORT. I HAD CRUISE CONTROL SET TO 75MPH. WITH NO WARNING, MY REAR WHEELS LOCKED UP. MY TRUCK SKIDDED INTO A BRIDGE. STATE FARM RECOMMENDED MY VEHICLE BE TAKEN TO PURIFOY CHEVROLET FOR REPAIRS. WHEN I WAS NOTIFIED BY PURIFOY AND STATE FARM THAT MY VEHICLE WAS REPAIRED, I ASKED THE PURIFOY SHOP MANAGER, MY STATE FARM AGENT, AND MY STATE FARM CLAIMS REPRESENTATIVE IF THE VEHICLE HAD BEEN INSPECTED FOR THE CAUSE OF THE LOCKED-AXLE CONDITION WHICH CAUSED THE CRASH AND INJURED ME. ALL STATED THE VEHICLE HAD BEEN INSPECTED, REPAIRED, AND CERTIFIED SAFE TO DRIVE. I PAID MY DEDUCTIBLE AND DROVE HOME THE VEHICLE AND PARKED IT IN MY GARAGE. WITHIN DAYS, I USED THE VEHICLE AND THE AXLE LOCKED UP AGAIN - BADLY WORSENING MY PHYSICAL INJURIES FROM THE FIRST CRASH AND CAUSING ME TO BE PUT INTO SEVERAL MORE WEEKS OF PHYSICAL THERAPY. I AM STILL UNDER A DOCTOR'S CARE. AND, I AM STILL IN PHYSICAL THERAPY RECOVERING FROM THE INJURIES. MY PHYSICAL THERAPIST HAS NOTED INTO MY MEDICAL RECORDS THAT THE SECOND OCCURRENCE GREATLY PROLONGED MY HEALING BY ADDING ADDITIONAL INJURY TO THAT WHICH PREVIOUSLY OCCURRED FROM THE FIRST CRASH. AFTER THIS SECOND OCCURRENCE, I TOOK MY VEHICLE TO A LOCAL SHOP. THE SHOP MANGER LOCALLY STATED THIS WAS A WELL-KNOWN CONDITION OF CHEVROLET TRUCKS: THE REAR AXLE VENT TUBE WAS MANUFACTURED TOO SMALL; THE TUBE PLUGS; THIS FORCES AXLE GREASE INTO THE EMERGENCY BRAKE HUB; THE EMERGENCY BRAKE BECOMES SATURATED AND SWELLS TO CLOSE PROXIMITY TO THE HUB; WHEN THE BRAKE HEATS UP, IT AUTOMATICALLY APPLIES AND CANNOT BE RELEASED UNTIL THE WHEEL ROLLS SLIGHTLY BACKWARD. THE LOCAL SHOP MANAGER REPLACED BOTH AXLE SEALS, CLEANED AND RESIZED THE VENT, AND INSTALLED NEW EMERGENCY BRAKES. THIS CORRECTED THE LOCKED WHEEL/AXLE CONDITION. *TR

COMPLETE LOSS OF FRONT BRAKE SYSTEM WHILE DRIVING. I NOTED A SOFT PEDAL WHILE SITTING AT A TRAFFIC LIGHT AND ON THE NEXT BRAKE APPLY THERE WAS LITTLE OR NO DECELERATION UNTIL THE PEDAL WAS NEAR THE FLOOR. THE REAR WHEELS LOCKED UP MOMENTARILY WHILE SLOWING THE VEHICLE AT THE EXTENT OF PEDAL TRAVEL. AFTER STOPPING THE VEHICLE, I NOTED A STEADY STREAM OF BRAKE FLUID COMING FROM THE LINE WHEN THE BRAKE WAS APPLIED. THE BRAKE LINE RUNNING TO THE ABS UNIT UNDER THE DRIVER SIDE DOOR HAD A LARGE LEAK IN AN AREA OF HEAVY CORROSION. UPON FURTHER INSPECTION I FOUND THAT MOST OF THE BRAKE LINES HAD HEAVY CORROSION ON THE VEHICLE ALTHOUGH NO OTHER LEAKS WERE NOTED. *KB

WHILE PULLING OUT OF PARKING LOT OF INSPECTION STATION ON TO SIDE STREET, ON SLIGHT HILL, I DEPRESSED MY BRAKE PEDAL AND IT WENT ALL THE WAY TO THE FLOOR. THE TRUCK SLOWLY STOPPED EVEN THOUGH I WAS ONLY DOING APPROXIMATLY 5 MPH. WHEN I GOT OUT AND LOOKED UNDER THE TRUCK I SAW BRAKE FLUID COMING FROM UNDER THE DRIVER SIDE OF THE TRUCK. THE INSPECTOR HAD TOLD ME THAT THE LINES LOOKED TO BE CORRODED AND I WOULD NEED TO GET THEM REPLACED IN A FEW YEARS. ONCE THE BRAKE FAILURE OCCURED HE CAME AND LOOKED AGAIN AND WAS SHOCKED THAT IT WAS AN INSTANT BRAKING. *TR

ALL BRAKE HYDRAULIC LINES ARE RUSTED, ALL FUEL SUPPLY LINES ARE RUSTED, EXCESSIVE RUST ON FRAME AND OTHER UNDERCARRIAGE COMPONENTS, BRAKE ROTORS, CALIPERS ALL COVERED WITH EXCESSIVE. RUST. THESE DEFECTS HAVE SERIOUS SAFETY IMPLICATIONS, WHICH COULD RESULT IN INJURY OR DEATH TO THE VEHICLE OCCUPANTS OR OTHERS. GM SHOULD BE REQUIRED TO ISSUE A RECALL ON THESE VEHICLES AND REPLACE ALL MAJOR CORRODED BRAKE COMPONENTS WITH NON CORROSIVE METALS, BRAKE FLUID LINES, FUEL LINES, RUSTED FRAMES AND ANY OTHER COMPONENTS. MANY ACCIDENTS WILL BE OCCURRING BECAUSE OF BRAKING FAILURES AND FRAME FAILURE. THIS RECALL SHOULD BE ISSUED IMMEDIATELY BEFORE ANY OTHER FAILURES OCCUR. THESE GM TRUCKS ALSO HAVE DEFECTIVE STEERING BOXES THAT FEEL LOOSE WHEN ROUNDING CORNERS. I HAVE HAD A 1995, 2001, 2002 CHEVY AND GMC WITH SAME PROBLEM THEY NEVER STOOD BEHIND THIS PROBLEM OTHER THAN TO PUT SOME GREASE IN WHICH WAS A TEMPORARY FIX. *TR

I WAS MOVING MY 2002 CHEVY SILVERADO 2500 HD FROM ITS NORMAL PARKING SPOT TO HOOK UP TO OUT TOWABLE RV. WHILE ALIGNING TO THE RV SUDDENLY THE BRAKE PEDAL HIT THE FLOOR. I NOTICED 2 MORE BRAKE LINES HAVE RUPTURED. YES 2 MORE, I HAVE ALREADY REPLACED 2 BRAKE LINES. AS OF AUGUST 14 2011 I HAVE WRITTEN AN EMAIL TO CHEVROLET AS MY VEHICLE SITS IN THE DRIVEWAY WITH RUPTURED, RUSTED BRAKE LINES. I DO NOT EVEN WANT TO IMAGINE THE CONSEQUENCES OF A RUPTURED BRAKE LINE WHILE EMPTY OR TOWING OUR RV AT NORMAL DRIVING SPEEDS. I TRULY FEEL MY FAMILY'S LIFE IS AT RISK IN THIS VEHICLE. FURTHERMORE I CAN SPECULATE THAT THE RESALE VALUE HAS BEEN EFFECTED. MORALLY I COULD NOT SELL THIS VEHICLE KNOWING THERE IS A MAJOR SAFETY ISSUE LOOMING. *TR
