ON 10/29/2011 THE ENGINE WAS BLOWING GRAYISH WHITE SMOKE. THE ENGINE STARTED LOSING OIL PRESSURE. CHECKED THE OIL, FOUND DIESEL IN THE OIL. THE OIL LEVEL WAS 6" HIGHER ON DIPSTICK. IT IS THE FUEL INJECTION SYSTEM ON THE 2002 DURAMAX DIESEL. THE FUEL INJECTORS HAVE FAILED. I UNDERSTOOD THAT CHEVROLET HAS PUT A RECALL ON AL…

ON 10/29/2011 THE ENGINE WAS BLOWING GRAYISH WHITE SMOKE. THE ENGINE STARTED LOSING OIL PRESSURE. CHECKED THE OIL, FOUND DIESEL IN THE OIL. THE OIL LEVEL WAS 6" HIGHER ON DIPSTICK. IT IS THE FUEL INJECTION SYSTEM ON THE 2002 DURAMAX DIESEL. THE FUEL INJECTORS HAVE FAILED. I UNDERSTOOD THAT CHEVROLET HAS PUT A RECALL ON ALL 2002 AND EARLY 2003 MODELS. TOOK IT TO DEREK SCOTT AUTO PARK WHICH IS THE CLOSEST CHEVROLET DEALER/SERVICE DEPARTMENT. AFTER RUNNING DIAGNOSTICS THEY TOLD US THAT THE REPLACEMENT OF THE FUEL INJECTORS WOULD BE COVERED 100% BY GM. LATER CALLED BACK AND SAID WE WOULD HAVE TO PAY HALF IN THE AMOUNT OF $2,251.88. THEY WILL NOT ALLOW US TO TALK TO THE GM REP. WE NEED TO KNOW IF THIS IS VALID OR NOT. WE THOUGHT RECALLS WERE PAID FOR BY THE COMPANY I.E. GM IN THIS CASE. THANK YOU FOR YOUR HELP IN THIS MATTER. *TR

I WAS DRIVING SOUTH ON MD-235 IN LEXINGTON PARK, MD WHEN THE LIGHT AT THE INTERSECTION OF MD-235 & FDR BLVD. TURNED YELLOW. I HAD LITTLE ROOM TO STOP AND APPLIED THE BRAKES FORCEFULLY, SLOWING TO APPROXIMATELY 25 MPH WHEN THE PEDAL WENT TO THE FLOOR AND I RAN THROUGH THE INTERSECTION AS THE LIGHT TURNED RED. NO CARS WERE IN FRONT OF ME; AN ACCIDENT DID NOT OCCUR. I USED THE EMERGENCY BRAKE TO STOP AND OPENED THE HOOD, THINKING I HAD A BRAKE MASTER CYLINDER FAILURE. I NOTED FLUID DRIPPING FROM UNDERNEATH THE CHASSIS BY THE DRIVER'S DOOR, & ON FURTHER INSPECTION, FOUND A RUPTURE IN A CORRODED BRAKE LINE. I DROVE HOME USING THE EMERGENCY BRAKE (RURAL AREA; APPROXIMATELY 12 MILES), LIGHTLY PRESSING THE BRAKE PEDAL WHEN STOPPING WITH THE EMERGENCY BRAKE TO TURN THE BRAKE LIGHTS ON. ONCE HOME, I FOUND VIRTUALLY EVERY STEEL BRAKE LINE THROUGHOUT THE VEHICLE BADLY CORRODED. AN INTERNET SEARCH PROVIDED INFORMATION THAT THIS IS A PREVAILING PROBLEM WITH 1999-2004 CHEVROLET TRUCKS OF ALL MODELS. A PROBLEM THIS PREVALENT WITH THIS HIGH OF A SAFETY CONCERN NEEDS A MANUFACTURER'S RECALL ISSUED FOR THESE VEHICLES. I AM THE SECOND OWNER OF THIS VEHICLE. *TR

WAS DRIVING ON ROAD WHEN DRIVER PULLED IN FRONT OF ME, I HAD TO A QUICKLY APPLIED BRAKES TO SLOW DOWN. WHEN PUSHED DOWN THE BRAKE PEDAL JUST WENT SOFT AND MUSHED DOWN. NO BRAKING ABILITY WAS POSSIBLE. HAD TO SWERVE INTO ON COMING TRAFFIC TO AVOID MAJOR COLLISION. OTHER CARS SWERVED OUT OF MY WAY. ~300 YARD DOWN THE ROAD THE TRUCK FINALLY CAME TO ROLLING STOP USING LOWER GEAR AUTO TRANSMISSION TO SLOW TRUCK DOWN. AFTER STOPPING SAW BRAKE FLUID POUR OUT OF FRONT ENGINE COMPARTMENT. UPON RETURN HOME SAW NO SIGN OF LEAKS IN DRIVEWAY. ALSO THERE WAS NOT VISIBLE LOSS OF BRAKE FLUIDS LEVEL NOR SOFTENING OF BRAKE PEDAL PRIOR TO THIS SUDDEN AND COMPLETE LOSS BAKES. FLUIDS ARE CHECKED ATLEAST MONTHLY. SO BRAKE LINE OR LINES RUPTURED SUDDENLY WITHOUT WARNING. THE POTENTIAL FOR DISASTER IS HUGE. THE HYDRAULIC BRAKE LINES APPEAR TO HAVE TO THINNED OUT FROM EXCESSIVE CORROSION AND THEN BURST (NOT LEAK) WHEN HEAVY BRAKE PRESSURE IS APPLIED WHICH IS THE WORST TIME FOR BRAKES TO FAIL. THIS IS PERSONAL USE VEHICLE NOT USED FOR COMMERCIAL WORK. HOWEVER IT IS DRIVEN AND USED IN THE SNOW BELT IN THE WINTER. IF YOU OWN ONE OF THESE TRUCKS AND LIVE IN THE SNOW BELT COMPLETELY INSPECT REPLACE YOUR LINES BEFORE SOMEONE DIES. FAILURE POINT WAS IN FRONT AREA UNDER HOOD NEAR LEFT WHEEL RIGHT ON BRACKET WHERE 4 LINES BEND. THESE ARE LARGE VEHICLES AND THE FAILURE GAVE NO OBVIOUS WARNING SIGNS PRIOR TO FAILURE. *TR

INTERNAL COMPONENTS WEAR A SMALL HOLE IN THE REAR OF THE CASE HOUSING ALLOWING THE FLUID TO LEAK OUT WITHOUT YOU KNOWING IT. ONCE THE FLUID IS GONE THE GEARS GRIND DOWN TO THE POINT WHERE THE TRANSMISSION LOCKS UP AND YOU SKID TO A STOP. I'VE BEEN TOLD THIS IS STILL AN ON GOING PROBLEM ALL THE WAY UP TO THE 2010 MODEL YEAR. *KB
