2003 CHEVROLET SUBURBAN 1500 Electrical System Problems

MY ENTIRE INSTRUMENT PANEL DOES NOT ALWAYS WORK WHEN I START MY TRUCK. IT WILL OCCASIONALLY COME TO LIFE AFTER DRIVING A BIT OR SOMETIMES IT DOESN'T WORK AT ALL. NO PATTERN AS TO WHEN, WHERE OR DRIVING CONDITIONS. STARTED A FEW MONTHS AGO WHERE IT WOULD ALWAYS WORK SHORTLY AFTER I STARTED THE ENGINE AND HAS PROGRESSIVELY GOTTEN WORSE,

THE BATTERY KEEPS GOING DEAD AND SOMETHING IS NOT SHUTTING THE CAR DOWN CAUSING A PARASITIC BATTERY DRAW KILLING BATTERY I HAVE GONE THROUGH 4 BATTERY AND AFTER ABOUT 3 DAYS OR 4 THE TRUCK DOES NOT START AND 2HEN I TAKE IT TO AUTOZONE THEY SAY ITS DEAD AND GIVE ME A NEW BATTERY AND TRIED LOOKING UP ISSUE AND SEE ALOT OF PEOPLE HAVING ISSUES AND WHEN I TOOK TO CHECK ALTERNATOR OR STARTER NOTHING THEY ARE GOOD

THE ANTI THEFT SYSTEM CAUSED THE ENGINE TO QUIT GOING DOWN THE HI WAY SEVERAL TIMES AND WAS VERY DANGEROUS SOME OF THE TIMES AND LEFT US STRANDED SOMETIMES. GM ACTS LIKE THEY DO NOT KNOW WHAT IS WRONG BUT THERE IS AMPLE INFO ON THE INTERNET AND EVEN A FIX BUT IT DISABLE THE ATS, IT TURNS OFF THE FUEL TO THE INJECTORS KILLING THE ENGINE. THIS HAPPENED MANY TIMES. WE HAD TO BE TOWED TWICE BECAUSE IT WOULD NOT RESTART.

WHEN DRIVING VEHICLE KEPT FALLING DEAD ON HIGHWAY AND CITY STREETS

TL* THE CONTACT OWNS A 2003 CHEVROLET SUBURBAN 1500. WHILE DRIVING 65 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE VEHICLE WAS OPERATING AS DESIGNED. THE FAILURE RECURRED MULTIPLE TIMES. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 99,000.

MY '03 CHEVROLET SUBURBAN HAS DEVELOPED WHAT APPEARS TO BE A VERY COMMON CONDITION WHERE THE ENTIRE INSTRUMENT CLUSTER BECOMES INOPERABLE. FOR EXAMPLE, WHILE TRAVELING AT LOW, IN TOWN SPEEDS, THE SPEEDOMETER WILL HAVE READINGS IN THE 60S, 70S' AND 80S. WHILE IN THE PARK POSITION, THE SPEEDOMETER WILL READ 55MPH. THIS IS ABSOLUTELY A SAFETY ISSUE AND I AM REALLY SHOCKED THAT THE NHTSA HASN'T FORCED A RECALL. THERE ARE LITERALLY THOUSANDS OF REPORTS ONLINE OF THIS EXACT PROBLEM. GENERAL MOTORS IS AWARE THAT THIS IS A WIDE SPREAD PROBLEM, AS THEY EVEN EXTENDED. GENERAL MOTORS EVEN PROVIDED OWNERS WITH A SPECIAL COVERAGE THAT EXTENDS THE WARRANTY ON THE INSTRUMENT PANEL CLUSTER FOR THE CONDITION DESCRIBED ABOVE, AS LONG AS THE VEHICLES AGE AND MILEAGE FALLS WITHIN CERTAIN PARAMETERS. THOSE PARAMETERS ARE THE MAIN REASON FOR MY COMPLAINT. THOSE PARAMETERS ARE 1) 7 YEARS OF THE IN SERVICE DATE,...

I CAN UNLOCK TRUCK WITH KEY OR REMOTE PUT KEY IN START AND DASH LIGHTS COME ON BUT NO START. AFTER BEING TOLD IT WAS THE FUEL PUMP, THE STARTED, AND KEY I KNOW IT HAS SOMETHING TO DO WITH THE ANTI-LOCK. I HAVE REPROGRAMMED IT SEVERAL TIME BUT EACH TIME A DIFFERENT WAY. I HAVE RESEARCH IT ON LINE AND IT IS A ON GOING PROBLEM WITH GM CARS AND TRUCKS. HOWEVER I AM NOT SURE IF IT IS A RECALL. I AM RECENTLY THE SECOND CAR OWNER OF THIS TRUCK AND EXPERIENCING THIS MAJOR PROBLEM. I AM A SINGLE MOTHER WITH CHILDREN AND GRANDCHILDREN AND THIS IS NOT GOOD FOR ME AT NIGHT OR DURING THE DAY IF AT A SHOPPING CENTER. I HAVE HAD TO HAVE IT TOWED TO MY HOME THEN THE NEXT DAY IT STARTED. IF ANY ONE CAN HELP ME PLEASE EMAIL [XXX] INFORMATION...

EVER SINCE WE PURCHASED THIS HUGE PILE OF JUNK, IT HAS BEEN EVERY PROBLEM TO CHANGING FUEL PUMP SEVERAL TIMES, CATALYTIC CONVERTERS,BATTERIES,MAJOR ELECTRICAL PROBLEMS, EVERY GAUGE IN THE VEHICLE IS OFF FROM GAS GAUGE TO SPEEDOMETER TO COOLANT! THERE IS NOT ANYTHING THAT IS NOT WRONG WITH IT. AFTER THOUSANDS OF DOLLARS AND SO MANY TIMES OF BEING STRANDED ON THE SIDE OF THE ROAD WITH 4 LITTLE KIDS IN THE DEAD OF WINTER WITH NO HEAT. I WOULD LIKE A LIFETIME WARRANTY FROM CHEVROLET TO COVER ANY EXPENSE INCURRED WHILE OWNING SUCH A PIECE OF CRAP AND FOR THE HUMILIATION I HAVE INCURRED BY BEING SEEN IN A CHEVY BECAUSE THEY ARE JUNK!!!!!OR WOULD LIKE BOOK VALUE OF VEHICLE SO I CAN GO BUY A FORD BECAUSE THEY RUN FOR 250,000 MILES PLUS!!! NOT 125,000. *TR

TL* THE CONTACT OWNS A 2003 CHEVROLET SUBURBAN 1500. THE CONTACT STATED THAT WHILE IDLING AT A STOP SIGN, THE SPEEDOMETER PROVIDED AN ERRONEOUS READING OF 60 MPH. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THE SPEEDOMETER CLUSTER NEEDED TO BE REPLACED. THE VEHICLE NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 103,000.

I WAS DRIVING MY 2003 CHEVROLET SUBURBAN DOWN THE ROAD AND MY SPEEDOMETER STOPPED WORKING. I LOOKED ONLINE AND I FOUND OVER 40 INCIDENTS ON WWW.SAFECAR.GOV ALONE. WHATS THE PROBLEM WITH GETTING THIS SAFETY PROBLEM FIXED. I CAN GO TO THE DEALER AND GET IT FIXED FOR $500 OR MORE. DO PEOPLE NEED TO GET HURT OR DIE BEFORE THIS PROBLEM IS NOTICED BY CHEVROLET OR GMC? *TR

JUST FINISHED DRIVING VEHICLE FOR 1 HOUR AT HIGHWAY SPEEDS WITHOUT INCIDENT. PARKED CAR FOR 5 MINUTES, UPON TRYING TO RESTART, THE CAR DISPLAYED "REDUCED ENGINE POWER" ON THE DRIVER INFORMATION CONSOLE. APPROXIMATELY 8 RESTARTS AND THE MESSAGE DID NOT DISPLAY. DROVE CAR 5 MINUTES AND PARKED IT FOR 1 HOUR, UPON RESTART DISPLAYED SAME MESSAGE, CAR WAS VIRTUALLY UNDRIVEABLE. 3 RESTARTS LATER MESSAGE NO LONGER DISPLAYED. THIS MESSAGE HAS NOW INTERMITTENTLY OCCURRED EVER SINCE SEEMINGLY WITHOUT ANY PATTERN. THE MESSAGE IS RELATED TO A FAILURE IN THE "DRIVE BY WIRE" SYSTEM THAT ALLOWS FOR THE ELIMINATION OF A PHYSICAL CABLE FROM THE GAS PEDAL. IT CAUSES THE CAR TO BE COMPLETELY UNDRIVEABLE UNTIL SEEMINGLY RANDOMLY FIXING ITSELF. *TR

"REDUCED ENGINE POWER" LIGHT COMES ON AND TRUCK SLOWS TO LESS THAN 10 MPH AND THE POWER STEERING STOP WORKING. THIS HAS HAPPENED SIX TIMES IN THE LAST YEAR. 1ST INCIDENT I TOOK IT TO THE DEALER AND THEY SAID NOTHING WAS WRONG WITH IT. DIAGNOSTICS PERFORMED AND NOTHING CAME BACK WRONG. I THINK THE WIRING TO THE THROTTLE IS POSSIBLY TO BLAME. IF I HIT A BUMP IN THE ROAD OR CROSS RAILROAD TRACKS, THE REDUCED ENGINE POWER CAN COME ON. I HAVE A HUNCH AFTER RESEARCHING ONLINE & FINDING THAT SEVERAL OTHER PEOPLE HAVE THE SAME PROBLEM, THAT LEADS ME TO BELIEVE THAT CHEVY KNOWS ABOUT IT & IS DOING NOTHING ABOUT IT. "TYPICAL"!! I AM VERY DISPLEASED, ESPECIALLY BECAUSE I LOVE MY SUBURBAN. I SUGGEST AN INVESTIGATION & RECALL OF THIS PROBLEM.I ASK THAT CHEVY TAKES RESPONSIBILITY FOR POOR QUALITY & REPAIRS THE PROBLEM PRONTO! OH, AND...

WE ARE HAVING SERIOUS ELECTRICAL ISSUES WITH OUR 2003 CHEVROLET SUBURBAN 1500 Z71. IT STARTED WITH THE SEAT WARMERS ONLY WORKIING OCCASIONALLY, THEN WHEN I WAS TRYING TO START IT ONE DAY THE DS AUTOMATIC POWER SEAT DEPLOYED ME AND SMASHED MY CHEST AND LEGS ALL THE WAY INTO THE STEERING WHEEL AND DASH I WAS PINNED AGAINST THE STEERING WHEEL AND DASHBOARD UNTIL MY HUSBAND HEARD ME SCREAMING AND CAME TO GET ME - IT DID THIS ON ITS OWN, I HADN'T TOUCHED A THING OTHER THAN TURN THE KEY TO START POSITION. THEN THE DS POWER SEAT BUTTONS STARTING WORKING IN REVERSE I.E. PUSHING FORWARD ON THE BUTTON SENDS YOU BACKWARDS AND PUSHING BACK SENDS YOU FORWARD, THEN THE SERVICE 4WD LIGHT CAME ON THE DIC AND STAYED ON FOR AWHILE, THE SEAT WARMERS STARTED TO WORK AGAIN ON OCCASION AND THEN QUIT ALTOGETHER...AGAIN., NOW THE CLUSTER PANEL...

GOT A 2003 CHEVORLET SURBURAN. THE REAR DOOR BE SHOWING OPEN N THE OIL GAUGE,TEMPERATURE GAUGE,RPM, N SPEEDOMETER NOT WORKING. *TR

I WAS DRIVING TO A STORE IN MY CITY WHEN IT FELT LIKE I WAS NOT DOING THE SPEED LIMIT AND GOING SLOWER THAN NORMAL. WHEN II GOT TO THE STORE AND TURNED OFF THE CAR, I SAW THAT THE SPEEDOMETER WAS REGISTERING 20 MPH. I STARTED THE CAR BACK UP AND IT DROPPED THE SPEED READING BY 5 MPH. I DID THIS 3 MORE TIMES TILL IT REGISTERED ZERO MPH. WHEN DRIVING HOME, I NOTICED THAT I WAS STILL DRIVING SLOWER THAN NORMAL AND WHEN I GOT HOME AND TURNED OFF THE CAR THE SPEEDOMETER READING WAS SHOWING 25 MPH. I LOOKED ONLINE AND SAW THAT OTHERS ARE HAVING THE SAME PROBLEM. THIS PROBLEM CONTINUES TO OCCUR EVERY TIME II AM DRIVING MY 2003 CHEVROLET SUBURBAN. I HAVE NOT TAKEN IT TO GET FIXED YET AND HAVE CONTACTED CHEVROLET TO SEE IF THEY WILL FIX THE PROBLEM FOR FREE...

I GOT A 2003 CHEVROLET SURB. THE REAR DOOR KEEP COMING OPEN ON IT OWN,THE SPEEDOMETER DOES NOT WORK,OIL GAUGE,AND THE TEMPERATURE GAUGE NOT WORK. IT HAD START NOW WHEN START TO CRANKED IT THE BRAKE BOOSTER LIGHT COME THE BATTERY LIGHT COME SAYING NOT CHARGING. *TR

2003 CHEVY SUBURBAN I THINK IT IS CALLED THE CLUSTER WHERE THE SPEEODOMETER AND THE FUEL GAGE ARE LOCATED. FUEL GAGE DOES NOT WORK AND SPEEDOMETER IS STUCK . AIR BAG LIGHT HAS GONE ON TWICE TOOK TO VEHICLE TO DEALER THEY CHANGED FRONT SENSOR AND THE LIGHT CAME BACK ON A MONTH LATER 06/20/2010. *TR

SPEEDOMETER FLUCTUATES, INDICATES VARIOUS SPEEDS OTHER THAN ACTUAL SPEED. NEVER A STANDARD OFFSET FROM ACTUAL SPEED. MIGHT INDICATE 20 MPH AT 55 MPH ACTUAL AS MEASURED BY GPS ONE TIME, THEN 10 MPH AT 60 MPH ACTUAL ANOTHER TIME. *TR

THE SPEEDOMETER ON OUR 2003 CHEVROLET SUBURBAN RANDOMLY STOPS WORKING. WE UNDERSTAND THAT IT IS A DEFECT AND THAT IT WILL ONLY BE REPLACED BY CHEVROLET IF THE VEHICLE HAS LESS THAN 70,000 MILES. OUR SUBURBAN HAS 85,000 MILES ON IT. SINCE IT IS A DEFECT IN THE INSTRUMENT CLUSTER, AND NOT BECAUSE OF WEAR AND TEAR, CHEVROLET SHOULD REPLACE IT FREE OF CHARGE. WE CAN'T AFFORD TO PAY THE $550+ TO HAVE IT REPLACED SO WE WILL DRIVE IT WITHOUT THE SPEEDOMETER WORKING, WHICH IS UNSAFE. *TR

SPEEDOMETER HAS FAILED. SHOWS 120 MPH, EVEN WHEN SHUT DOWN. IT SLOWLY BEGAN TO GO FROM ZERO AT STARTUP, TO 35 AT STARTUP, TO 70 AT STARTUP AND NOW TO 120. APPARENTLY, THERE IS A KNOWN DEFECT IN THE INSTRUMENT CLUSTER WHICH CHEVY AND DEALERS ARE AWARE OF. *NM
