2003 CHEVROLET SILVERADO 2500 Engine Problems

THE EXHAUST MANIFOLD BOLTS ARE BREAKING ON THE 6.0 ENGINE. I THINK GM SHOULD DO THIS REPAIR SINCE I HAVE TALKED TO SEVERAL PEOPLE AND THIS IS VERY COMMON. IT IS A DESIGN DEFECT AS FAR AS I AM CONCERNED. I HAVE PUT UP WITH THIS AS IT STARTED AS A SMALL LEAK BUT IS GETTING WORSE.

5 OUT OF 8 EXHAUST MANIFOLD BOLTS ARE BROKEN ON THE PASSENGER SIDE OF VEHICLE AND 2 ON DRIVERS SIDE. I HAVE 120K MILES ON VEHICLE.

THE EXHAUST MANIFOLD BOLTS ARE BREAKING CREATING A FIRE HAZARD FROM THE HOT EXHAUST REACHING THE WIRING HARNESS, IT IS ALSO CREATING FUMES IN MY CAB. FIRST NOTED A NOISE A WEEK AGO, FOUND IT TO BE A EXHAUST LEAK AND THE LEAK HAS GRADUALLY GOTTEN WORSE. I AM UNABLE TO NOT DRIVE TO THE TRUCK DUE TO WORK.

TRAVELING ON HIGHWAY WHEN SMOKE STARTED COMING FROM THE DASHBOARD. PULLED OVER AND WITHIN SEVERAL MINUTES THE WHOLE TRUCK WAS ON FIRE.

TL* THE CONTACT OWNED A 2003 CHEVROLET SILVERADO 2500. WHILE DRIVING 25 MPH, THE CONTACT MADE A LEFT TURN AND THE REDUCED ENGINE POWER LIGHT ILLUMINATED. THE STEERING FAILED AND THE VEHICLE CRASHED INTO A TREE. THE AIR BAGS DID NOT DEPLOY. THE VEHICLE WAS DESTROYED. THE CONTACT SUFFERED NERVE PAIN IN THE BACK AND LEGS FROM THE IMPACT OF THE CRASH. MEDICAL ATTENTION WAS NOT RECEIVED. A POLICE REPORT WAS FILED AND THE VEHICLE WAS TOWED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 196,000.

TL* THE CONTACT OWNS A 2003 CHEVROLET SILVERADO 2500. WHILE DRIVING 40 MPH, THE REDUCED ENGINE POWER LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE STALLED IN THE MIDDLE OF THE HIGHWAY, BUT THE CONTACT WAS ABLE TO PULL OVER TO THE SIDE OF THE ROAD. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED, BUT NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 195,000.

AT FREEWAY SPEEDS I NOTICED THE OIL PRESSURE HAD DROPPED TO ALMOST 2 OUT OF 10 ON THE PRESSURE GAUGE. I STOPPED AS SOON AS POSSIBLE AND LET THE ENGINE COOL FOR 20 MINUTES. I CHECKED THE OIL LEVEL AND COLOR. IT WAS OK IN BOTH RESPECTS. AFTER ANOTHER 30 MINUTES I RESTARTED THE ENGINE AND CONTINUED HOME. I WATCHED THE PRESSURE GAGE FOR ANOTHER HOUR AND SAW THE PRESSURE READING CONTINUE TO FALL TO A DANGEROUS LEVEL BUT THERE WAS NOTHING I COULD DO. THE NEXT DAY I TOOK THE TRUCK TO THE CHEVY DEALER IN EL CENTRO, CA 92243 FOR THEIR ANALYSIS. THEY SAID IT WAS ONLY POOR OIL AND NEEDED CHANGING. I LET THEM SERVICE THE TRUCK AS THEY WISHED. THEY ALSO SCANNED (SWEPT) THE GAUGES AND CHANGED THE OIL AND SENT ME ON MY WAY. THE NEXT DAY IT DID THE SAME THING. I DID NOT...

MY 2003 CHEVY 2500 HD HAS AN EXHAUST MANIFOLD LEAK AND THIS IS AN ONGOING AND CHRONIC PROBLEM WITH THESE VEHICLES. I CAN SEE EVIDENCE OF HOT EXHAUST GASES LEAKING INTO THE ENGINE COMPARTMENT. *TR

TL* THE CONTACT OWNS A 2003 CHEVROLET SILVERADO 2500 HD. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 55 MPH, HE NOTICED A TICKING SOUND FROM THE VEHICLE. THE NOISE BECAME LOUDER AND THE CONTACT LATER DISCOVERED THAT THE BEARING AND TIMING CHAIN WERE DAMAGED. ADDITIONALLY, THE TRANSFER CASE DID NOT CONTAIN ANY FLUID. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR FURTHER INSPECTION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 195,000.

WHILE DRIVING, THE CHECK ENGINE LIGHT COMES ON AND "REDUCED ENGINE POWER" IS ILLUMINATED ON THE DASH. STEPPING ON THE GAS DOES NOTHING. THE VEHICLE JUST COASTS ALONG AND RUNS ROUGH. I HAVE TO PULL OVER AND SHUT IT OFF FOR A FEW SECONDS. SOMETIMES IT DOESN'T CLEAR THE PROBLEM RIGHT AWAY AND NEEDS TO BE RESTARTED SEVERAL TIMES. THERE IS NO RHYME OR REASON AS TO WHEN THIS HAPPENS. IT HAPPENS ALMOST EVERY DAY, ON BUSY EXPRESSWAYS OR ON MAIN ROADS AND SIDE ROADS. THE GAS PEDAL LOSES COMMUNICATION WITH THE THROTTLE BODY. THIS IS NERVE WRACKING WHEN DRIVING 65 MPH ON THE EXPRESSWAY AND ALL OF A SUDDEN THE VEHICLE WONT RESPOND TO STEPPING ON THE GAS PEDAL. TRYING TO GET OVER SEVERAL LANES TO THE SIDE OF THE ROAD IS DANGEROUS WHEN THERE IS NO ACCELERATION. IT IS ALSO BAD WHEN ON A BUSY, MAIN ROAD, THE...

WE WERE TRAVELING EAST ON I-90 IN MASS. TRAFFIC CAME TO A SUDDEN STOP. WHEN THE BRAKES WERE APPLIED THE TRUCK BEGAN TO SLOW AND THEN THE BRAKE PEDAL WENT TO THE FLOOR. UPON INVESTIGATION AFTER THE CRASH WE FOUND AT LEAST TWO BADLY CORRODED BRAKE LINES THAT HAD BURST.*JB

THIS IS THE 3RD TIME FOR INJECTORS IN OUR 2003 INJECTORS, NOT ONE INJECTOR...ALL 8. LUCKY THIS TIME JUST 4 HRS. FROM HOME AND SOMEBODY TO COME WITH TRAILER TO PICK US UP. SEEMS INJECTORS ONLY LAST 20 TP 30,000 MILES AND THEY ARE GONE CRACKED. GM WONT BACK THEM KNOWING THEY ARE A PROBLEM, AND $5,000.00 EACH TIME THEY ARE REPLACED. GM INJECTORS ARE JUNK OUT THE DOOR AND LEAVING HUNDREDS OF OWNERS STRANDED ON HIGHWAY AND SUFFERING TOW BILL AND REPAIRS, BUT THIS TIME WE ALMOST GOT REAR ENDED BY A SEMI TRUCK WHICH SLAMMED ON HIS BREAKS BLOWING A TIRE TO MISS US AND OUR HORSE TRAILER WITH 3 HORSES IN IT. THE ABF TRUCKER THAT ALMOST HIT US IN THE REAR PULLED OVER AS WE DID, AND TOLD HIM THE TRUCK JUST STALLED, WE PULLED THE HOOD AND DIESEL FUEL WAS ALL OVER THE PLACE AND...

FUEL INJECTORS REPLACED ALL 8 INJECTORS AT 34901 MILES, AGAIN AT 85039, AND AGAIN AT 141,000 AND NOW AGAIN AT 185,000. *TR

I NOTICE A TICKING FROM THE ENGINE COMPARTMENT OVER THE LAST COUPLE OF DAYS. I ASSUMED IT MAY BE AN EXHAUST LEAK AND I WAS CORRECT. THIS VEHICLE HAS A STAINLESS STEEL EXHAUST SYSTEM THAT SHOULD LAST A LIFETIME YET THERE SEEMS TO BE A REAL PROBLEM WITH EXHAUST MANIFOLD BOLTS BREAKING OFF, CAUSING EXHAUST LEAKS WHICH POLLUTE THE AIR AND RUIN OTHER VEHICLE COMPONENTS SUCH AS THE CATALYTIC CONVERTER. I AM ALSO THINKING THAT THE MANIFOLDS ARE WARPING CAUSING THE BOLTS TO BREAK. THESE REPAIRS ARE VERY EXPENSIVE AND/OR TIME CONSUMING. STAINLESS STEEL BOLTS WOULD HAVE POSSIBLY PREVENTED THIS PROBLEM. I UNDERSTAND THAT THIS PROBLEM AFFECTS 1999 TO 2007 VEHICLES AND I HEREBY REQUEST THAT A RECALL BE FORCED UPON THE MANUFACTURER. THE MANUFACTURER HAS BEEN BUILDING CARS LONG ENOUGH TO KNOW BETTER. THERE IS ALSO A VIDEO ON YOU - TUBE THAT EXPLAINS THIS CONDITION. *TR
