2004 Chevrolet Silverado 2500

I OWN A 2004 CHEVROLET SILVERADO AND HAVE A PULSATING ACTION IN MY ABS BRAKES WHEN COMING TO STOPS AT SLOW SPEEDS. I HAVE ALREADY REPLACED ALL FOUR BRAKES AND ROTORS AND IT DID NOT CHANGE THE PROBLEM. I ONLY HAVE 50,000 MILES ON MY TRUCK. I LIVE IN PENNSYLVANIA AND SAW ON THE INTERNET THAT THERE IS A RECALL ON SOME VEHICLES A LITTLE OLDER THAN MINE BUT NOT MY YEAR OF VEHICLE. I HAVE THE SAME PROBLEM AS ALL OF THESE OTHER PEOPLE. THIS HAS BEEN HAPPENING FOR QUITE SOME TIME NOW. *TR

THIS IS HOW IT STARTED.. I HAVE A 2004 CHEVY SILVERADO 2500 HD. AS I DROVE DOWN THE ROAD THE DOORS WOULD LOCK AND UNLOCK ON THEIR OWN, AND THE TRUCK WOULD LOSE RPM'S AND WOULD ACT AS IF THE TRUCK SHUT OFF AND RESTARTED ITSELF. ALSO THE CHECK ENGINE LIGHT WOULD BLINK WITH THE LOCKING AND UNLOCKING OF THE DOORS. DID THIS OFF AND ON A FEW TIMES AS WE BABIED IT HOME. GOT IT HOME IN THE DRIVEWAY AND IT THREW 2 CODES CAMSHAFT POSITION SENSOR HIGH VOLTS AND LOW VOLTS. SO WE REPLACED THE CAMSHAFT POSITION SENSOR. TRUCK DROVE FINE FOR 4 DAYS. HOWEVER ON THE 5TH DAY WE ATTEMPTED TO DRIVE THE TRUCK AND AS WE WERE DRIVING DOWN THE ROAD THIS TIME THE ENGINE LIGHT CAME ON AND STAYED ON AND DOORS STARTED LOCKING AND UNLOCKING AGAIN ON THEIR OWN AS WELL AS THE DIC READ SERVICE BRAKE SYSTEM AND THE TRUCK COMPLETELY DIED IN THE MIDDLE OF TRAFFIC, WE WERE ABLE TO PULL OVER INTO A PARKING LOT AND TRUCK RESTARTED LONG ENOUGH TO GET HOME. AT THIS POINT THE GM DEALER WASN'T SURE OF THIS PROBLEM AND WHAT CAUSES IT BUT STATED TO UNPLUG THE BATTERY AND RESET THE COMPUTER(AFTER SPEAKING TO 4 DIFFERENT GM DEALERS MIND YOU). WOW LOW AND BEHOLD FIXED THE PROBLEM FOR ABOUT 45 MINUTES, AS WE AGAIN TRIED TO SEE HOW FAR WE COULD MAKE IT BEFORE IT STARTED ACTING UP AGAIN. ONLY THIS TIME DOORS WOULD LOCK AND UNLOCK AND ALL KINDS OF WEIRD THINGS WERE GOING ON, FOR EXAMPLE DOORS LOCKING AND UNLOCKING, TRUCK STALLING AND RESTARTING, IDOL WAS RUFF AND NOISY, SERVICE ENGINE LIGHT CAME ON AND STAYED ON, AND THE DIC READ THIS TIME REDUCED ENGINE POWER!! AND AT THIS POINT WE WERE ONLY ABLE TO GO 15 MILES AN HOUR AND THANKFULLY WE WERE ON A ROAD WITH NO TRAFFIC AND WERE ABOUT 2 MILES FROM OUR HOME. ALSO IN THE MIST OF ALL OF THIS THE TRUCK WAS CHIMING AND THE TRUCK THOUGHT IT DIDN'T HAVE ANY BRAKES AT THIS POINT THANKFULLY WE WERE ABLE TO GET THE TRUCK TO COME TO A COMPLETE STOP. WE HAVE HAD THIS TRUCK FOR LESS THAN 1 YR AND IT ONLY HAS 82,000 ON IT AND NOONE SEEMS TO BE ABLE TO TELL US WHAT IS WRONG WITH IT. *TR

ABS SYSTEM ACTIVATES ON LEFT FRONT AT SLOW ROLL. NORMAL SLOW STOP NOT SAFE IN TRAFFIC. NOW HAPPENS ALL THE TIME.I AM AN AUTOMOTIVE TECH. AT COLLISION RESTORATION IN FAIRFIELD NJ..THE SENSOR IS REMOVABLE AND ND REPLACEABLE ...IF... GM WOULD SELL IT SEPARATELY,BUT THEY WANT YOU TO SPEND $300 FOR A HUB ASSEMBLY (THAT YOU DON'T NEED)TO GET THE SENSOR. *TR

IN OCT.2008 I BROUGHT MY 2004 CHEVROLET SILVERADO 2500HD TO POUGHKEEPSIE CHEVROLET IN POUGHKEEPSIE, N.Y. FOR AN OIL AND FILTER CHANGE AND N.Y. STATE INSPECTION. WHILE WAITING FOR THE WORK TO BE COMPLETED I WAS ASK TO COME AND LOOK AT THE VEHICLE WHILE IT WAS ON THE LIFT. I WAS SHOWN THE FOUR BRAKE ROTORS (STILL ON THE VEHICLE). THE INSIDES OF THE BRAKE ROTORS WERE EXTREMELY DAMAGED WITH RUST, WOULD NOT PASS INSPECTION AND NEEDED REPLACEMENT. WHEN I EXPRESSED MY DISMAY AND DISGUST (THE VEHICLE ONLY HAD 28.5K MILES ON IT) I WAS TOLD THIS HAD OCCURRED "BECAUSE THE VEHICLE WASN'T DRIVEN ENOUGH AND WE LIVE IN THE RUST BELT". ANYWAY I AUTHORIZED THE WORK TO BE DONE, I NEEDED THE N.Y. STATE INSPECTION AND IT WAS OBVIOUS THE BRAKES WERE UNSAFE. AFTER DWELLING ON THIS, I DECIDED TO DO SOME RESEARCH AND CAME TO FIND THAT THE BRAKE SYSTEMS IN MANY GM LIGHT TRUCKS HAVE BEEN PROBLEMATIC FOR SEVERAL YEARS AND GIVEN SIMILAR RESPONSES VARYING SLIGHTLY TO FIT GM'S NEEDS TO MASK THE ROOT OF THE PROBLEM, THE MAJORITY BEING RUST AND CORROSION. IT IS OBVIOUS GM REMAINS IN DENIAL OF THIS DEFECT AND REFUSES TO CORRECT OR REIMBURSE FOR REPLACEMENT. MY FIRST REGRET IS ALLOWING GM TO DO THE WORK. FROM WHAT I HAVE READ, PREVIOUS VICTIMS THAT REPLACED THEIR ROTORS WITH GM PRODUCTS HAD THE SAME SUBSEQUENT RESULT. I CAN'T BELIEVE THEY HAVE NOT BEEN SUED. I WILL NEVER BUY A NEW GM VEHICLE AGAIN. IT IS NO WONDER THEY ARE GOING BANKRUPT. THEIR PROBLEM IS NOT THE PAY AND BENEFITS THEY GIVE THEIR WORKERS, IT IS WHERE THEY CUT CORNERS IN THEIR PRODUCT (CHEAP MATERIAL & OUTSOURCING) TO LINE THEIR CEO GREEDY POCKETS. THEY COULDN'T CARE LESS ABOUT THE PUBLIC SAFETY. *TR

SPEEDOMETER AND TACHOMETER INDICATE ERRATIC SPEEDS, THEY WILL LOCK UP AT ANYWHERE FROM 40 TO 120MPH AND 4 TO 6000 RPM, HAS BEEN ACTING THIS WAY FOR THE LAST 5 MONTHS, USUALLY AT HIGHWAY SPEEDS. PURCHASED FROM ORIGINAL OWNER SEPT 2008 WITH 84,000 MILES ON IT, DON'T KNOW IF IT WAS AN EXISTING PROBLEM OR NOT, DEALER SAYS IT IS OUT OF WARRANTY AND IS NOT COVERED. SAFETY ISSUE FOR SPEEDOMETER, OR OTHER GAUGES SHOULD THEY FAIL (FUEL, OIL PRESSURE ETC). *TR

BRAKES FAIL OR HAVE REDUCED STOPPING WHEN COMING TO STOP DEALER DIAGNOSTICS AS FLUID LEAKING PAST ACCUMULATOR VALVE. IN ORDER TO REPAIR,WOULD NEED HYDRO BOOST REPLACED. 2004 CHEVROLET SILVERADO,DURAMAX DIESEL WITH ALLISON AUTOMATIC TRANS. WAS TOLD BY DEALER THERE WERE 2 RECALLS ON THIS VEHICLE TYPE FOR BRAKE HYDROBOOST, BUT THAT MY CONCERN WAS NOT INCLUDED BECAUSE NO EXTERNAL LEAK. ALSO, WAS INFORMED NO HELP AT THIS TIME TO REPAIR
