VEHICLE EXHIBITED HARD STARTING FOR A FEW DAYS, AND THEN WAS FOUND WITH A LARGE PUDDLE OF FUEL UNDER IT IN THE MORNING, AND WAS CONTINUING TO LEAK. UPON INSPECTION, ALL STEEL FUEL LINES, AT EVERY POINT OF CONNECTION, AND AT EVERY BRACE, HAVE THICK, SCALY, FLAKING RUST. THE CORROSION IS SEVERE. IN MOST LOCATIONS, NEARING THE POINT OF FAILURE, AND IN AT LEAST ONE SPOT, RESULTED IN A PIN HOLE LEAK, WITH A SIGNIFICANT QUANTITY OF FUEL LEAKING ONTO THE VEHICLE AND THE GROUND. THE STEEL BRAKE LINES WERE ALSO FOUND TO HAVE A SIMILAR DEGREE OF CORROSION, AND WILL PROBABLY FAIL IN THE NEAR TERM. *TR

THE CONTACT STATED THAT WHILE DRIVING 35 MPH AND TOWING A WAVE RUNNER, THE BRAKES WERE APPLIED BUT THE VEHICLE DID NOT STOP UNTIL CRASHING INTO THE REAR OF ANOTHER VEHICLE. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO A PRIVATE MECHANIC, WHO INSPECTED THE VEHICLE AND INFORMED THE CONTACT THAT THE BRAKE LINES FAILED DUE TO CORROSION ON THE DRIVER'S SIDE OF THE FRAME. THE PRIVATE MECHANIC REMOVED AND REPLACED THE BRAKE LINES, UNIONS, AND BRAKE FLUID. THE MANUFACTURER WAS AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 129,779 AND THE CURRENT MILEAGE WAS 129,979. UPDATED 09/14/11*LJ UPDATED 2/22/12 *CN

EXCESSIVE BRAKE LINE RUST AND FAILURE WITH LOSS OF SERVICE BRAKES ON GM LIGHT TRUCKS. I RECENTLY HAD AN EXPERIENCE WHERE THE METAL BRAKE LINES BROKE UNEXPECTEDLY ON MY 2002 CHEVROLET SILVERADO 2500HD LIGHT TRUCK. THE BRAKE PEDAL WENT TO THE FLOOR WHILE ATTEMPTING TO STOP AT A NEIGHBORHOOD STOP SIGN. THE VEHICLE HAD TO BE STOPPED FROM APPROXIMATELY 10MPH USING THE PARKING BRAKE AND DOWNSHIFTING. NO ACCIDENT OCCURRED. A LOCAL SERVICE STATION FOUND THAT MOST ALL OF THE VEHICLE'S BRAKE LINES WERE EXCESSIVELY RUSTED. ALL BRAKE LINES WERE REPLACED AT A COST OF $650. *TR

I HAVE A 2002 CHEVY SILVERADO 2500HD NEARLY CAUGHT FIRE YESTERDAY. A LEAK DEVELOPED IN THE POWER BRAKE BOOSTER/HYDRO-BOOST SYSTEM AND POWER STEERING FLUID WAS LEAKING ONTO MY HOT EXHAUST MANIFOLD. SMOKE WAS POURING FROM UNDER MY HOOD. I SUSPECT A SMALL FIRE BECAUSE OF THE AMOUNT OF SMOKE. BY THE TIME I PULLED OFF THE ROAD AND OPENED THE HOOD ALL I SAW WAS SMOKE FROM SOMETHING LEAKING ON THE MANIFOLD. I GOT ONLINE AND FOUND THIS RECALL INFORMATION FOR 2004-2005 CHEVY TRUCKS BUT NOT 2002. I WANTED TO INFORM YOU THAT THERE MAY BE A NEED TO RECALL 2002 SILVERADO TRUCKS AS WELL. RESEARCHING DIESELPLACE.COM AND DIESELPAGE.COM THIS PROBLEM IS COMMON AND WIDESPREAD. ---------------------------------------------------------------------------------- MARCH 2005 DEAR CHEVROLET CUSTOMER: THIS NOTICE IS SENT TO YOU IN ACCORDANCE WITH THE REQUIREMENTS OF THE NATIONAL TRAFFIC AND MOTOR VEHICLE SAFETY ACT. REASON FOR THIS RECALL: GENERAL MOTORS HAS DECIDED THAT A DEFECT, WHICH RELATES TO MOTOR VEHICLE SAFETY, EXISTS IN CERTAIN 2004 MODEL YEAR CHEVROLET KODIAK AND CERTAIN 2004 AND 2005 MODEL YEAR CHEVROLET AVALANCHE, EXPRESS, SILVERADO, AND SUBURBAN VEHICLES. ON SOME OF THESE VEHICLES, THE HYDRAULIC BRAKE BOOSTER'S PRESSURE ACCUMULATOR MAY CRACK AND/OR SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL VEHICLE OPERATING CONDITIONS. IF A SEPARATION WERE TO OCCUR AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA. IN ADDITION, THE PRESENCE OF THIS CRACK OR FRACTURED SURFACE COULD ALLOW THE HYDRAULIC FLUID TO LEAK FROM THE ACCUMULATOR CIRCUIT OF THE BOOSTER ASSEMBLY. THE LOSS OF FLUID WOULD CAUSE INCREASED STEERING AND BRAKING EFFORT. WHAT WILL BE DONE: YOUR CHEVROLET DEALER WILL INSPECT THE HYDRAULIC BRAKE BOOSTER, AND REPLACE IT IF NECESSARY. THIS SERVICE WILL BE PERFORMED FOR YOU AT NO CHARGE. *TR

COMPLAINT REPORTS ALLEGE POOR WELD QUALITY AND/OR BENDING OF THE SUBJECT VEHICLE ORIGINAL EQUIPMENT TRAILER HITCH RECEIVER.THE AGENCY'S INVESTIGATION INCLUDED ANALYSIS OF MANUFACTURER AND AGENCY INCIDENT REPORTS, REVIEW OF POLICE REPORTS, ANALYSIS OF THE AGENCY'S FATAL ANALYSIS REPORTING SYSTEM, A VEHICLE OWNER SURVEY, INSPECTION OF TOW VEHICLES/HITCHES AND ANALYSIS OF FAILED PARTS.INCIDENTS OF WELD FAILURE WERE RARE AND ASSOCIATED WITH VERY LOW-SPEED DRIVING (TURNING, BACKING AND SUDDEN STOPPING).INCIDENTS OF BENDING WERE ASSOCIATED WITH IMPROPER TRAILER HITCH ADJUSTMENT OR OVERLOADING. A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL MONITOR THIS ISSUE AND RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.SEE DOCUMENT SEARCH FILE FOR ADDITION INFORMATION.
