2003 CHEVROLET SUBURBAN Complaints

NO EVENT LEADING TO FAILURE. HEARD CLUNK - TRANMISSION WENT OUT 48,000 MILES. VEHICLE HAS NEVER TOWED ANYTHING. REPLACED TRANSMISSION - SHOP NOW SAYS REAR DIFFERNTIAL ALSO BAD.

THE FACTORY TRAILER HITCH ON MY 2003 CHEVY SUBURBAN BROKE WHILE I WAS TOWING A TRAVEL TRAILER. THE WELDS WERE IMPROPERLY DONE. THE "U" BRACKET THAT HOLDS THE SQUARE RECEIVER TORE AS IF WEAK METAL. *JB

2003 CHEVROLET SUBURBAN. SPEEDOMETER ACTS VERY ERRATICALLY, OFTEN INDICATING INCORRECT SPEED. THE PROBLEM CAUSING THE SPEEDOMETER TO FAIL ALSO SEEMS TO AFFECT THE OIL PRESSURE GAUGE. 2004 GMC K1500 Z71- SPEEDOMETER IS ERRATIC ALSO. *NM

2003 SUBURBAN INSTRUMENT CLUSTER STOPPED WORKING, SPEEDOMETER IS ERRATIC, SOMETIMES IT GETS STUCK OTHER TIMES IT READS EXTREMELY HIGH ALSO BATTERY GAUGE IS DEAD. I HAVE FOUND NUMEROUS WEB FORUMS WITH COUNTLESS THREADS DEDICATED TO COMPLAINTS ON 2003 GM INSTRUMENT CLUSTERS. WHOLE CLUSTER MUST BE REPLACED, AS IT IS VERY DANGEROUS TO NOT KNOW YOUR SPEED. *JB

I HAVE A 2003 CHEVROLET SUBURBAN AND THE SPEEDOMETER STAYS AT 30 MPH WHEN THE VEHICLE IS STOPPED. WHEN TRAVELING DOWN THE ROAD I HAVE NO IDEA HOW FAST I AM GOING BUT AM SURE THAT 110 MPH IS NOT CORRECT. *JB

I HAVE A 2003 CHEVY SUBURBAN WITH 46,000 MILES AND THE SPEEDOMETER NOT WORKING. I CALLED THE DEALER AND HE SAID IT IS A COMMON PROBLEM BUT I AM STILL GOING TO HAVE TO PAY TO FIX IT. THE SPEEDOMETER WAS READING 120 MILES PER HOUR AND I WAS GOING LESS THAN 50 MILES PER HOUR. I RESEARCHED THIS PROBLEM ON THE INTERNET AND I FOUND HUNDREDS OF OTHER PEOPLE WITH THE SAME PROBLEM IN TAHOES AND SILVERADOS. *NM

2003 CHEVY SUBURBAN, WHILE DRIVING STEADY @ AT APPROXIMATELY 65 MPH, SPEEDOMETER BECAME ERRATIC, INDICATING 0 MPH; SLOWED TO 55 AND EXITED HIGHWAY. SHUT ENGINE OFF AND SPEEDOMETER WENT TO 55 MPH AND REMAINED. STARED ENGINE AND INDICATOR WENT TO 30 MPH. ALL OTHER INDICATIONS AND GAUGES SEEMED TO INDICATE NORMAL. *JB

I WAS RECENTLY PULLED OVER FOR SPEEDING . THE PATROLMAN CLOCKED MY @68 MPH IN A 45 MPH SPEED ZONE. MY SPEEDOMETER SHOWED 52 MPH. NOW 2 WEEKS LATER IT READS 75 MPH PARKED IN MY DRIVE. I CAN BE DRIVING 30 MPH AND MY SPEEDOMETER WILL READ 105-100 MPH OR DRIVING SOMEWHERE AROUND 50-60 MPH AND IT WILL BE PEGGED OUT ABOVE 120 MPH. I AM READING ON THE INTERNET AND I'M NOT THE ONLY ONE HAVING THIS PROBLEM. *JB

THE SPEEDOMETER QUIT WORKING (GETS STUCK AND REPORTS IN ACCURATE SPEEDS OR STICKS BELOW 0 MPH) ON MY 2003 SUBURBAN WITH ONLY 59000 MILES. I AM TOLD THIS IS A COMMON PROBLEM WITH THE INSTRUMENT CLUSTER AND THAT GM ISSUED A TSB BUT NO RECALL EVEN WITH THE MANY REPORTS AND COMPLAINTS OF SAFETY CONCERNS. I AM TOLD THE REPAIR COST WILL BE $500-$700. I ALSO HAD TO REPLACE A BAD A/C COMPRESSION COSTING $1K AND INTAKE GASKETS $320 IN THE LAST 3 MONTHS. THIS IS RIDICULOUS FOR THIS NEW OF A VEHICLE. I THOUGHT GM BUILT BETTER QUALITY PRODUCTS THAN THIS. IT'S A SAFETY ISSUE NOT KNOWING HOW FAST YOU ARE GOING OR IF THE OTHER GAUGES ARE WORKING CORRECTLY. I AM NERVOUS PUTTING MY WIFE AND 4 KIDS IN THIS VEHICLE DUE TO THESE SAFETY CONCERNS. I WILL NOT RISK MY FAMILY'S SAFETY DUE TO THIS LOW QUALITY OF PRODUCT. *JB

VEHICLE STALLS AT HIGHWAY SPEEDS, SPECIFICALLY, UNDER LOAD (UP HILLS, ACCELERATING, ETC...) WHEN GAS IS GIVEN, THE CAR STALLS. THE TACH STILL READS A NUMBER, AND ALL CABIN ELECTRONICS REMAIN ACTIVE, WITHOUT SHOWING ANY HINT OF A PROBLEM (NO SPIKE, DIMMING OF LIGHTS, ETC...) ENGINE JUST DIES. (AGAIN, THIS TYPICALLY HAPPENS AT HIGHWAY SPEEDS [40-80 MPH.]) NO CHECK ENGINE LIGHT COMES ON, AND THERE IS NO INDICATION OF THE POSSIBILITY OF A FAILURE ELECTRONICALLY [IE, NO "MESSAGES."] THE ONLY DISCERNIBLE SYMPTOM IS SLUGGISHNESS ON THE PART OF THE ACCELERATOR, AS IF SLAMMING THE ACCELERATOR TO THE FLOOR WOULD CUT OUT THE ENGINE, BUT SLOWLY PUSHING THE ACCELERATOR TO THE FLOOR WOULD PERMIT (SOMEWHAT) THE ACCELERATION. (MIND YOU, THAT I ALMOST NEVER PUSH MY ACCELERATOR ALL THE WAY TO THE FLOOR.) FURTHER, ANY ACCELERATION (HOWEVER SLIGHT,) CAN CAUSE THE ENGINE TO STALL WHEN THE CAR IS IN THE MOOD TO WANT TO STALL. (THE PROBLEM IS SOMEWHAT INTERMEDIATE - IT HAS HAPPENED ABOUT 10-15 TIMES IN THE PAST 6 MONTHS, ONCE ON THE THROGSNECK BRIDGE IN NY.) THE PROBLEM HAS HAPPENED ON NUMEROUS OCCASIONS, (THE FIRST TIME AROUND THE BEGINNING OF JULY '06, [ABOUT 2 OCCASIONS ON ONE DAY, 4 MORE ANOTHER DAY THAT WEEK,) AND THEN AGAIN AROUND OCTOBER 10TH, ON WHICH THERE WERE ANOTHER 5 OR SO INCIDENTS. ON OCT 11TH, I BROUGHT THE CAR BACK TO THE DEALERSHIP, AND THEY SAW NO ERROR CODES, SO COULDN'T DO ANYTHING TO DIAGNOSE THE PROBLEM. ONSTAR WAS SIMILARLY UNABLE TO DIAGNOSE ANY ERRORS WITH THE VEHICLE. *JB
