I PURCHASED THIS TRUCK USED APPROX. ON 10/2016. SHORTLY AFTERWARDS I BEGAN TO SMELL GAS. I FOUND THE FUEL LINES RUSTED THROUGH AND HAD TO REPLACE THE FUEL LINES FROM THE TANK TO THE ENGINE. LAST WEEK A BRAKE LINE FAILED DUE TO RUST PULLING UP TO A STOP LIGHT. THE PEDAL WENT RIGHT TO THE FLOOR. A LINE HAD TO BE REPLACED FROM THE ABS PUMP TO THE REAR AXEL. I WAS TOLD AT THAT TIME THE REST OF THE BRAKE LINES WERE IN VERY POOR CONDITION. THE COST TO REPAIR WILL EXCEED THE VALUE OF THE TRUCK.

TOOK TO DEALER SEVERAL TIMES AND TOLD THEY COULDN'T FIND ANYTHING WRONG. I WAS TOLD BY A MECHANIC STUDENT AT SCHOOL THAT THE SENDING UNIT AND WIRING WAS BAD. I RECEIVED A GM NOTICE ABOUT THE FIX BUT DEALER SAID THAT WASN'T THE PROBLEM I HAVE 72,000 MILES ON TRUCK AND IT STILLS JUMPS TO EMPTY FOR NO REASON.

FIRST INCIDENT OF THE FUEL SENSOR FAILING (LOW FUEL LIGHT AND FUEL GAUGE INDICATOR FALSE) WAS AT 68,400 MILES. 2ND TIME FAILED ON 04/16/2011 AT 98,500 MILES WHICH COSTS ME ANOTHER 800.00 BUCKS. THIS IS THE 3RD TIME ITS STARTING TO ACT UP AGAIN AT 118,300 MILES, AND WILL PROBABLY COST ME AGAIN!! I CAN SEE IT HAPPENING ONCE, BUT NOT UNDERSTAND HOW IT CAN HAPPEN 3 TIMES THAT IS RIDICULOUS, NOT TO MENTION THE EXPENSE! CHEVROLET SHOULD HAVE HAD SOME TYPE OF RECALL ON THIS OR LEAST FIGURE OUT WHAT IS CAUSING THE PROBLEM. THERE IS NO DOUBT IN MY MIND THIS IS A DEFECT WITH THE PART AND VERY EXPENSIVE TO REPAIR. I HAVE RESEARCHED THIS PROBLEM AND IT SEEMS A LOT OF PEOPLE HAVE EXPERIENCED THIS ISSUE. THIS ISSUE COULD BE DANGEROUS AND PEOPLE HAVE LITTLE CHOICE FOR SAFETY REASONS BUT TO CORRECT THIS PROBLEM AT GREAT EXPENSE. THIS NEEDS A RECALL ..NOT EVERYONE HAS $800.00 LAYING AROUND AND GM SHOULD FIX THIS FOR FREE ESPECIALLY WHEN IT HAPPENS A 2ND, 3RD TIME! COME ON GM YOUR REP IS ON THE LINE.. *TR

WHILE DRIVING ON A RESIDENTIAL STREET I ATTEMPTED TO APPLY THE BRAKES AND THE BRAKE PEDAL WENT TO THE FLOOR. AFTER ABOUT 20 FEET THE TRUCK DID STOP WITH THE BRAKE PEDAL ALMOST ON THE FLOOR. THE TRUCK HAD TO BE TOWED AND THE FRONT BRAKE LINES WHERE RUSTED AND LEAKING AND REPLACED. THE REAR LINES ARE ALSO RUSTED AND NEED TO BE REPLACED.THE TOTAL COST IS ABOUT $500.00. I HAVE HAD TO REPLACE THE FULE LINE AS IT ALSO RUSTED AND LEAKED, THAT COST WAS $900.00. APPARENTLY GM HAS HAD NUMEROUS PROBLEMS WITH THIS. IN OVER 40 YEARS I HAVE NEVER SEEN LINES RUST THROUGH LIKE THIS.IT IS A SEROIUS PROBLEM AND COULD HAVE RESULTED IN A MAJOR ACCIDENT IF THE AREA HAD BEEN MORE CONGESTED AND SPEED GREATER.GM SHOULD BE PUTTING QUALITY MATERIAL ON SUCH A VITAL SYSTEM. ALSO THE REAR BRAKES WHERE ALMOST NON-EXISTENT DUE TO THE GM ABS DESIGN. THIS GIVES NO BRAKING ABILITY AND SHOULD NOT BE THAT WAY.AS FAR AS SAFETY GOES THIS SHOULD BE A NUMBER ONE ISSUE AS BRAKE FAILURE CAN BE LETAL, GAS LEAKING ISNT VERY SAFE EITHER.

I HAVE TRIED TO STAY WITH A GM PRODUCT BUT THE TRUCK I RECENTLY PURCHASED HAD THE FOLLOWING PROBLEMS,WHILE TRYING ALSO TO AVOID THE MOST COMMON PROBLEM OF THE GM BAD FRAME,BY THE WAY TOYOTA WARRANTIES THERE FRAMES. THE 1ST MONTH OF OWNERSHIP THE REAR SPRING SHACKLES BROKE THERE ARE 30 YEAR OLD TRUCKS THAT STILL DON'T HAVE THIS PROBLEM,I OWN ONE. NEXT ABOUT ANOTHER 30 DAYS GO BY THE ELECTRIC FUEL PUMP DECIDED TO DIE. THAT SO FAR BRINGS REPAIRS UP TO CLOSE TO 650.00 AFTER 60 DAYS. LAST WK. MY BRAKE LINE FAILED @ ABOUT 50 MPH,NO WARNING LIGHT RIGHT TO THE FLOOR.THIS TRUCK HAD BEEN TAKEN CARE OF . SHOULD I CONTINUE ABOUT THE HOLE IN MY WINDSHIELD FRAME EVERY TIME IT RAINS MY ASH TRAY IS FILLED WITH WATER. BY THE WAY I WAS QUOTED ABOUT 1400.00 FOR ALL THE BRAKE LINE REPAIRS. WTF GM WHO HAS THAT KIND OF MONEY FOR REPAIRS,I DONT. THE PUBLIC SHOULD BE COMPENSATED FOR SUBSTANDARD MATERIAL USE. *TR

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
