I HAVE A 2002 CHEVROLET 2500HD PICKUP WITH THE DURAMAX DIESEL ENGINE WITH JUST OVER 100,000 MILES ON IT. RECENTLY, WHILE SITTING AT A STOP SIGN, DARIK SMOKE WOULD COME FROM THE EXHAUST.

I HAVE A 2002 CHEVROLET 2500HD PICKUP WITH THE DURAMAX DIESEL ENGINE WITH JUST OVER 100,000 MILES ON IT. RECENTLY, WHILE SITTING AT A STOP SIGN, DARIK SMOKE WOULD COME FROM THE EXHAUST. IT NEVER DID THIS BEFORE SO I TOOK IT TO THE LOCAL DEALER TO FIND OUT WHAT THE PROBLEM MIGHT BE. THE DEALER TOLD ME THAT THE INJECTORS NEEDED TO BE REPLACED AT A COST OF ABOUT $4500. I CONTACTED GMC, THEY SET UP A CASE FILE AND GOT BACK TO ME IN ABOUT A WEEK TO TELL ME THAT I WAS BEYOND THE 7 YEAR EXTENDED WARRANTY AND SO THEY WOULD NOT COVER THE REPAIR. THE FACT THAT IT ONLY HAD ABOUT 1/2 OF THE 200,000 MILES COVERED IN THE EXTENDED WARRANTY DIDN'T SEEM TO COUNT FOR ANYTHING. ONE OF THE SELLING POINTS WHEN I PURCHASED THE VEHICLE WAS THAT IT SHOULD LAST FOR 200K TO 300K MILES WITHOUT NEEDING REPAIR. THE VEHICLE HAS BEEN USED PRIMARILY FOR PERSONAL TRANSPORTATION, NOT ABUSED, WITH ONLY OCCASIONAL TOWING OF A RELATIVELY LIGHT TRAILER. *TR

THE CAR WAS OPERATING NORMALLY AS I WAS LEAVING THE PARKING LOT AFTER SHOPPING. THE ENGINE WAS AT NORMAL OPERATING TEMPERATURE. THE ENGINE STALLED, LOST POWER BRAKES AND STEERING. THIS OCCURRED FIVE TIMES IN A PERIOD OF APPROXIMATELY ONE WEEK. THE ENGINE WOULD RESTART AFTER ONE MINUTE OR MORE. THERE WERE NO SES OR MIL INDICATIONS OR DTC CODES. I GOOGLED THE FAILURE AND FOUND SEVERAL PEOPLE WITH SAME PROBLEM. I ALSO FOUND A NHTSA RECALL 06083 FOR A 2001 YEAR MY VEHICLE IS A 2002. I TOOK THE VEHICLE TO THE CHEVROLET DEALER AND HAD THE CRANKCASE POSITION SENSOR REPLACED AND THAT SOLVED THE PROBLEM. TO ELABORATE ON THE PROBLEM IT DID OCCUR WHILE I WAS DRIVING DOWN THE HIGHWAY AT 65 MILES PER HOUR. THAT IS VERY SCARY AND AS THIS IS A TRUCK I COULD HAVE BEEN TOWING MY BOAT. I DO HAVE THE DEFECTIVE PART. IT SEEMS TO ME THAT ALL THE DEFECTIVE PARTS WERE NOT REMOVED FROM INVENTORY OR THE SOLUTION TO THE PROBLEM WAS INADEQUATE. *TR

BRAKE LINES DEVELOPED A LEAK DUE TO EXCESSIVE CORROSION. ALL LINES FROM THE BRAKE MASTER CYLINDER TO EACH WHEEL AND TO THE ABS UNIT HAD TO BE REPLACED, INCLUDING THE FLEXIBLE LINES. THE PROBLEM WAS FOUND AFTER NOTICING BRAKE FLUID DRIPPING FROM UNDER THE VEHICLE AND THE LOSS OF FLUID IN THE BRAKE FLUID RESERVOIR. *TR

THE CONTACT LOCATED A RECALL FOR THE FAILURE HOWEVER, THE DEALER ADVISED THE RECALL WAS LIMITED TO SPECIFIC STATES ONLY. THE CONTACTS VIN WAS NOT INCLUDED IN THE RECALL. A DIAGNOSTIC WAS PERFORMED WHICH DETERMINED THE FAILURE TO BE CAUSED BY THE RIGHT ABS SENSOR. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 80,000 AND THE CURRENT MILEAGE WAS 84,000.

2002 CHEVROLET SILVERADO 2500 HD WITHOUT WARNING, EXHIBITS VERY SOFT BRAKE PEDAL ACCOMPANIED BY SENSATION THAT BRAKE PEDAL "GOES TO THE FLOOR," APPARENT ACTIVATION OF ABS, AND DIFFICULTY STOPPING SAFELY. ORIGINAL EQUIPMENT FRONT BRAKE PADS AND ROTORS ARE INSPECTED BY SERVICE FACILITY AND DEEMED ACCEPTABLE FOR CONTINUED USE AT THIS TIME. REAR DISK BRAKE PAD AND ROTOR INSPECTED AND DEEMED UNSERVICEABLE DUE TO PREMATURE FAILURE APPARENTLY CAUSED BY EXTENSIVE, PROGRESSIVE UNDERCARRIAGE CORROSION THAT WAS OBSERVABLE FROM DELIVERY DATE OF VEHICLE WHEN PURCHASED NEW. REAR BRAKE PAD INABILITY TO "FLOAT" DUE TO EXTENSIVE CORROSION CAUSED PREMATURE REAR PAD AND REAR ROTOR FAILURE. BRAKE LINES ARE ALSO OBSERVED TO BE CORRODING IN AN EXCESSIVE, PREMATURE MANNER AS ARE VEHICLE FRAME AND TRAILER HITCH STRUCTURAL COMPONENTS. OBSERVATION OF SIMILARLY SITUATED PICK-UP TRUCKS MANUFACTURED BY OTHERS DO NOT DEMONSTRATE CORROSION OF THIS EXCESSIVE MAGNITUDE. *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.
