2004 Chevrolet Silverado 2500 electrical problems

ELECTRICAL SYSTEM

CHECK ENGINE LIGHT CAME ON AND "LOW ENGINE POWER" FLASHED WHERE THE ODOMETER IS. THIS CAUSED THE RPM'S NOT TO GO OVER 2800. CODE READER CLAIMS O2 SENSORS OR THROTTLE CONTROL MODULE OR CATALYTIC CONVERTOR ISSUES. WE DISCOVERED IT WAS NONE OF THE ABOVE. TO FIX PROBLEM CHANGE 3 RELAYS LOCATED UNDER HOOD IN FUSE BOX. RELAY #8864. THEN CLEAR CODES, SHOULD FIX ISSUE UNLESS CODE PERSISTS. RELAYS WILL CAUSE A FIRE IF NOT CHANGED OUT ASAP.

MANY OF THE VEHICLES IN THIS FAMILY SUFFER FROM RANDOM ELECTRICAL SHORTS AND OR POOR ELECTRICAL GROUNDING RELATING TO THE DRIVE BY WIRE THROTTLE ACTUATOR. THE RESULT IS THAT THE VEHICLE WILL GO INTO 'REDUCED ENGINE POWER' MODE RANDOMLY. IN THIS MODE THE VEHICLE WILL IDLE BUT NOT ACCELERATE OR DRIVE. THIS ISSUE IS WELL DOCUMENTED ON MESSAGE BOARDS WITH NO CONSISTENT FIX. THIS CONDITION EXPOSES AN EXTREME HAZARD AS THE VEHICLE CAN LOOSE POWER AT ANY TIME. THIS IS A SERIOUS SAFETY ISSUE THAT SHOULD BE INVESTIGATED. I HAVE HAD MY VEHICLE LOOSE POWER ON THE INTERSTATE AND ON HIGH SPEED 2 LANE ROADS WITH NO SHOULDER AND HEAVY TRAFFIC ON 4 OCCASIONS. NUMEROUS ATTEMPTS TO REPAIR THE ISSUE HAVE BEEN UNSUCCESSFUL.

DRIVING ON THE INTERSTATE AT 65-70 MPH TRUCK SHUT OFF NO POWER STEERING NO BRAKES SHOWING "REDUCED ENGINE POWER" ALMOST GOT INTO A WRECK WITH MY 2 YEAR OLD SON AND 70 YEAR OLD GRANDMOTHER...I STILL OWE $10,000 ON THIS HUNK OF CRAP...IT WENT AWAY AFTER A BROKEN WIRE WAS FIXED....BUT AS I SIT HERE IN MY TRUCK AT 3 AM BECAUSE I HAD TO MOVE IT I STARTED IT UP AND ONCE AGAIN REDUCED ENGINE POWER...JUST SO FRUSTRATING

AS WITH MANY OTHER POSTS HERE, I TOO HAVE HAD PROBLEMS WITH BOTH THE INSTRUMENT CLUSTER(BAD SPEEDOMETER AND GAUGE READINGS, "ELECTRICAL") AND ALSO THE TRANSFER CASE WITH HOLES WEARING THROUGH THE CASE, "PUMP SLAP". EVERYTHING I HAVE RESEARCHED HAS LED TO ISSUES IN BOTH PROBLEMS. I HAVE SINCE REPLACED BOTH PROBLEMS BUT STILL NOTHING BACK FROM GM. WHAT A SHAME THAT THESE AND ALL OTHER ISSUES CAN'T BE ADDRESSED BY GM. I HAVE NOT YET HAD A PROBLEM WITH THE BRAKES, YET, BUT I TELL YOU, IT WILL BE LOOKED INTO. THESE BOTH HAVE HAPPENED UNDER NORMAL DRIVING CONDITIONS.

ELECTRICAL SYSTEM

I EXPERIENCED A SUDDEN LOSS OF ENGINE POWER WHILE TRAVELLING AT HIGHWAY SPEED. I AM THE ORIGINAL OWNER OF A 2004 CHEVROLET SILVERADO 2500 FOUR WHEEL DRIVE WITH THE DURAMAX DIESEL AND ALLISON TRANSMISSION. ON SUNDAY, OCTOBER 4, 2015, SHORTLY AFTER A FUEL STOP, I WAS TRAVELING ON INTERSTATE 24 NEAR PADUCAH, KY. AT APPROXIMATELY 65 MPH IN THE LEFT LANE WITH THE CRUISE CONTROL SET, I EXPERIENCED A SUDDEN LOSS OF POWER ACCOMPANIED BY A LOUD ENGINE RATTLING, AND THE CHECK ENGINE LIGHT CAME ON. WITH SOME DIFFICULTY IN HEAVY TRAFFIC, I WAS ABLE TO MANEUVER TO THE RIGHT SHOULDER OF THE ROAD. I WAS ABLE TO DRIVE THE VEHICLE AT ABOUT 25 MPH ON THE SHOULDER. SINCE I WAS JUST A FEW MILES FROM THE PADUCAH EXIT, I LIMPED THERE AND INTO A HAMPTON INN PARKING LOT. AAA RESPONDED AND TOWED THE TRUCK TO ROYAL OAKS CHEVROLET IN PADUCAH. SINCE IT WAS A SUNDAY, THE SERVICE DEPARTMENT WAS CLOSED. THE NEXT MORNING, THE DEALERSHIP'S SERVICE DEPARTMENT PULLED UP CODES PO202 AND P2149. THE SERVICE MANAGER REPORTED THAT THERE WAS A SERVICE BULLETIN ON THIS ISSUE AND THAT IT WOULD BE SEVERAL DAYS BEFORE THE REPAIR PARTS WOULD BE AVAILABLE. I LATER LEARNED THAT THE SERVICE BULLETIN IS #05-06-04-047C. THE BULLETIN ADDRESSES "A SEVERE REDUCTION IN ENGINE POWER (LIMP HOME MODE)" I WAS CHARGED $1,076 FOR REPAIRS FOR A KNOWN DEFECT THAT CHEVROLET KNEW ABOUT.

WHEN I GOT INTO THE VEHICLE TO START, THE DRIVER INFORMATION CENTER SAYS "UNKNOWN DRIVER". AS A RESULT OF THIS CONDITION, I CANNOT ADJUST MIRRORS, ROLL UP WINDOWS, OR GET HEADLIGHTS TO WORK. ALSO, THE GAUGES FOR VOLTAGE, OIL PRESSURE, TEMPERATURE, AND FUEL DO NOT WORK. THE RADIO DOES NOT WORK AS WELL. BECAUSE OF OVER ENGINEERING AND FAULTY PARTS I CANNOT USE THIS VEHICLE. I HAVE ALREADY HAD THE INSTRUMENT CLUSTER REPLACED AS PART OF A RECALL. MANY PEOPLE HAVE HAD THIS PROBLEM AS SEARCHED, WITH NO ANSWER. GENERAL MOTORS HAS FAILED TO PUT IN PLACE SAFETY SYSTEMS OR OVERRIDE FUNCTIONS TO ALLOW SAFE OPERATION OF THE VEHICLE. GM IS USING COMPUTER CONTROLS WHICH OFTEN FAIL TO CONTROL IMPORTANT SAFETY FUNCTIONS OF THE VEHICLE. I CURRENTLY HAVE THE VEHICLE AT THE DEALER AND THEY HAVE DISMANTLED THE BULK OF THE TRUCK TO DIAGNOSE THE PROBLEM. AFTER TWO DAYS IN THE SHOP, THEY STILL HAVE NOT FOUND THE PROBLEM. FAULTY ENGINEERING AND POOR PARTS HAVE LEAD TO THIS CONDITION. I HAVE BEEN A LIFELONG GM OWNER, BUT I WILL RECONSIDER THIS MOVING FOWARD. I AM SURE MY NEXT VEHICLES WILL BE OTHER BRANDS.

ONE BY ONE, THE GAUGES ON THE DASH HAVE STOPPED WORKING, STARTING WITH THE ENGINE TEMPERATURE GAUGE. THEN THE FUEL LEVEL GAUGE, SPEEDOMETER, TACHOMETER, OIL PRESSURE, AND FINALLY THE TRANSMISSION TEMPERATURE GAUGE ALL WENT OUT, LEAVING ONLY THE BATTERY VOLTAGE METER WORKING CORRECTLY. I KNOW AT LEAST THREE OTHER PEOPLE LIVING WITHIN 20 MILES OF MY HOUSE THAT HAVE ALSO HAD THIS PROBLEM WITH THEIR 2004 SILVERADOS.

I BOUGHT A 2004 CHEVY SILVERADO FROM MEDVED AND I FEEL IT HAS A PROBLEM AND GM SAYS IT'S WORKING AS DESIGNED. MY PROBLEM IS THE MESSAGE MODULE LED'S ARE SO DIM THEY CAN'T BE READ IN THE DAYLIGHT AND THE INSTRUMENT CLUSTER HAS BEEN REPLACED 3 TIMES BY MEDVED TO TRY AND FIX THE PROBLEM. THE P N R D D3 D2 LED"S ARE JUST FINE. THEY TOLD ME TO TAKE IT TO ANOTHER DEALERSHIP TO SEE IF THEY CAN FIX IT. I TOOK IT TO [XXX] AND A 18 YEAR SERVICE TECH SAID IT DOESN'T GET ANY BETTER AND GM SHOULD HAVE SENT OUT A RECALL BUT DIDN'T. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR THIS COULD BE A SAFETY ISSUE IF YOU CAN'T READ THE WARNINGS AND OTHER MESSAGES THAT APPEAR ON THE MODULE WHILE DRIVING.

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL

THE SPEEDOMETER REGISTERS 120MPH ALL THE TIME WHEN MOVING. WAS FIXED ONCE UNDER WARRANT. THE DEALER WHO FIXED IT IS NO LONGER IN BUSINESS. I PURCHASED A EXTENDED WARRANTY, NEVER USED IT. THE TRUCK HAS 55,000 MILES RIGHT NOW. DIESEL. $43,000 NEW. CHEVY CHANGED OUR ONSTAR TO DIGITAL. NO ONSTAR NOW.

ELECTRICAL SYSTEM

OIL PRESSURE GAUGE QUIT WORKING IN ABOUT 2009. TOOK INTO DEALERSHIP AND WAS TOLD WE WERE 4,000 MILES PAST THE RECALL OF THE CLUSTER. VERY EXPENSIVE REPLACEMENT!! SINCE THAT TIME THE SPEEDOMETER QUIT WORKING, THE TACHOMETER QUIT WORKING. VERY SCARY TO BE HAVING TO RELY ON TEMPERATURE GAUGES THAT I HOPE ARE WORKING CORRECTLY STILL, AND A GAS GAUGE THAT HOPEFULLY IS ALSO WORKING CORRECTLY. I CANNOT BELIEVE THEY DID NOT SUBMIT A FULL RECALL AND REPLACEMENT OF THIS INSTRUMENT CLUSTER WITHOUT AN EXPIRATION ON IT. SEEMS LIKE THIS IS A HUGE SAFETY ISSUE TO ME TO HAVE NON WORKING GAUGES DUE TO A FACTORY DEFECT!!

I RECENTLY PURCHASED IN CHEVY 2500 HD SILVERADO FROM AN INDIVIDUAL AND THE GAUGES ON THE DASH ARE NOT WORKING PROPERLY. LUCKILY, THE PERSON I BOUGHT IT FROM WAS HONEST ENOUGH TO LET ME KNOW THIS BEFORE I TEST DROVE THE TRUCK. HE TOLD HE HAD ALREADY SPOKE TO THE LOCAL CHEVY DEALER AND THEY SAID IT WAS A COMMON PROBLEM AND IT COULD BE REPAIRED UNDER WARRANTY IF THE VEHICLE HAD UNDER 75,000 MILES.THE TRUCK HAD 142,XXX WHEN I GOT IT. I TALKED TO ANOTHER MECHANIC AND HE ALSO VERIFIED THAT THIS IS A COMMON PROBLEM WITH THESE TRUCKS, AS IS A HOLE BEING EATEN UP IN THE TRANSFER CASE OF THE 4X4. THE REPAIR ESTIMATE I GOT IS $350. I THINK A CLASS ACTION LAWSUIT SHOULD BE FILED ON BEHALF OF ALL THE CURRENT OWNERS( OR PERSONS THAT HAD TO PAY FOR THIS REPAIR) AGAINST GM. I AM UNABLE TO MONITOR MY SPEED, TEMP, OIL PRESSURE, VOLTAGE, FUEL OR TRANS TEMP ACCURATELY BECAUSE OF THIS. IF THE MOTOR WERE TO BURN UP DUE TO OVERHEATING, I WOULD HAVE NO WAY OF KNOWING IT UNTIL IT WAS TOO LATE. IF ANYONE KNOWS OF A LAWYER WILLING TO TAKE ON A CASE SUCH AS THIS, I WILL BE MORE THAN WILLING TO SIGN MY NAME DUE TO THE FACT I AM HAVING TO PAY FOR THE REPAIR TO AVOID MORE SERIOUS DAMAGE TO THE VEHICLE OR A POSSIBLE OF LIFE IF THE VEHICLE WERE TO CATCH FIRE FROM OVERHEATING.
