2003 CHEVROLET SUBURBAN 1500 Complaints

AFTER AN INITIAL FAILURE OF THE HYDRAULIC BRAKE (LINE RUPTURED ABOUT TWO FEET BEHIND THE ABS VALVE) WHILE THE CAR WAS MOVING, AND AFTER THIS LINE WAS REPLACED, I INSPECTED THE REAR WHEEL BRAKE LINES AND NOTICED EXTREME CORROSION ON BOTH LINES THAT RUN FROM A JUNCTION CONNECTION ABOVE THE DIFFERENTIAL TO THE HOSES ON EACH CALIPER. WHILE CHECKING THE FITTINGS AND INSPECTING THE LEFT LINE IT LITERALLY CRUMBLED, BROKE AND STARTED LEAKING. I REPLACED BOTH LINES AND BLEED THE SYSTEM. THE CAR HAD BEEN INTO THE DEALER WITHIN LAST YEAR (APPROX.) FOR BRAKE LINE INSPECTION AFTER OBSERVING A LOT OF RUST. THE DEALER CLAIMED THAT LINES WERE OK AND THAT A LOT OF RUST WAS NORMAL AND OK. I HAD TO PAY FOR THIS INSPECTION. *TR

WAS HIT ON THE PASSENGER SIDE AND THE SIDE IMPACT AIRBAGS DID NOT DEPLOY. TRUCK THEN FLIPPED AND NO AIRBAGS DEPLOYED. *TR

FOR THE PAST 4 YEARS I HAVE OWNED A 2003 SUBURBAN 1500 Z71.3 OF THOSE YEARS I'VE HAD A/C PROBLEMS. WE HAVE REPLACED EVERYTHING AND ANYTHING THAT HAS TO DO WITH A/C. THOUSANDS OF DOLLARS AND NOW SOMETHING ELSE HAS COME UP. DRIVER SIDE HOT AIR BLOWS OUT AND PASSENGER SIDE COLD AIR COMES OUT. WE DON'T KNOW WHAT TO DO WITH THIS SUBURBAN ANYMORE. I HAVE FRIENDS WITH SUBURBANS AND HAVE THE EXACT SAME PROBLEMS WITH IT,WHAT CAN WE DO? *TR

2003 SUBURBAN SPEEDOMETER NOT WORKING. STARTED MALFUNCTIONING IN DECEMBER 2007, THE NEEDLE WOULD JUMP ALL OVER THE PLACE AND THEN STOPPED WORKING IN JULY. *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

WHEN APPLYING BRAKES TO AVOID HITTING A DEER, THE PEDAL WENT COMPLETELY TO THE FLOOR. NO ABS, NO PARTIAL PEDAL, STRAIGHT TO THE FLOOR. VEHICLE WAS TOWED TO CHEVROLET DEALER WHERE IT WAS DETERMINED THAT BOTH FRONT AND REAR BRAKE LINES NEEDED TO BE REPLACED DUE TO BRAKE LINE CORROSION. DEALER PROVIDED ROUGH ESTIMATE OF $1500 PLUS TAX TO REPAIR. *TR

TL* THE CONTACT OWNS A 2003 CHEVROLET SUBURBAN 1500. WHEN APPROACHING A STOP SIGN AND DEPRESSING THE BRAKES, THE ANTI-LOCK BRAKING SYSTEM WOULD ENGAGE UNNECESSARILY AND THE BRAKE PEDAL WOULD FALL TO THE FLOORBOARD. WHENEVER THE FAILURE WOULD OCCUR, THE BRAKES WOULD NOT ENGAGE AND THE VEHICLE WOULD FAIL TO STOP. THE DEALER WAS NOTIFIED AND WOULD OFFER NO ASSISTANCE. THE CONTACT HAS EXPERIENCED THE FAILURE FOR APPROXIMATELY TWO YEARS. THE FAILURE MILEAGE WAS 40,000 AND THE CURRENT MILEAGE WAS 59,000.

TL*THE CONTACT OWNS A 2003 CHEVROLET SUBURBAN 1500. HE STATED THAT ON NOVEMBER OF 2009 WHILE DRIVING APPROXIMATELY 25 MPH, HE NOTICED THE SPEEDOMETER WAS FAILING. THE SPEEDOMETER BEGAN TO INCREASE AND DECREASE IN SPEED UNTIL IT STOPPED WORKING. HE TOOK THE VEHICLE TO THE DEALER. THE DIAGNOSIS LOCATED THE FAILURE AS THE CLUSTER PROGRAM. THE DEALER REPLACED THE CLUSTER PROGRAM. THE COST FOR REPAIR WAS $500.00. THE MANUFACTURER TOOK A REPORT AND STATED THAT THEY WILL NOT ASSIST WITH THE REPAIR. THE FAILURE MILEAGE WAS 94,000 THE CURRENT MILEAGE WAS 106,000.

ABS WOULD INCORRECTLY ENGAGE WHEN STOPPING AT LOW SPEEDS (< 5 MPH). INCREASES STOPPING DISTANCE SINCE ABS STARTS PUMPING INSTEAD OF JUST APPLYING BRAKES. THIS HAPPENS ON IDEAL ROAD CONDITIONS AND AT LOW SPEED/NON SKIDDING STOPS. *TR MECHANIC REPLACED WHEEL HUB ASSEMBLY ON BOTH FRONT LEFT AND FRONT RIGHT WHEELS (WHEEL HUB INCLUDED NEW ABS SPEED SENSOR). PROBLEM WAS FIXED. THIS IS OBVIOUSLY A SAFETY ISSUE. GM HAS ALREADY RECALLED 99 - 2002 (MINE IS A 2003) SUBURBANS FOR THIS. MECHANIC INDICATED THAT ABS SENSORS WERE BADLY CORRODED (PRESUMABLY) FROM SALT GETTING INTO CONTACT WITH THE SENSOR. MECHANIC ALSO INDICATED THAT HE HAS FIXED THIS IN *MANY* SUBURBANS AND IN MANY CASES THAT CAME AFTER OWNERS HAD UNSUCCESSFULLY TRIED TO GET DEALERS TO FIX THE ISSUE. MECHANIC SAID DEALERS WERE REPLACING THE ABS COMPUTER, AT A COST OF THOUSANDS OF DOLLARS, AND PROBLEM STILL WASN'T FIXED. IMPORTANT NOTE: IT APPEARS THAT REGARDLESS OF WHETHER A RECALL IS DONE, DEALERS SHOULD AT LEAST BE AWARE OF THIS COMMON SAFETY PROBLEM WITH SUBURBANS FROM THIS TIME PERIOD. *TR

THE HIGH CENTER (3RD) BRAKE LIGHT ON MY 20003 CHEVY SUBURBAN HAS GONE OUT FOR THE THIRD TIME. I SEE MANY MANY SIMILAR VEHICLES WITH THEIR HIGH-CENTER (3RD) BRAKE LIGHTS OUT. THERE HAS TO BE SOME ELECTRICAL SYSTEM GLITCH TO CAUSE THE FAILURE. GM RECENTLY ANNOUNCED A RECALL TO REPLACE THE ENTIRE DASH BOARD BECAUSE OF ELECTRICAL PROBLEMS. THE PROBLEMS MAY BE RELATED THIS IS A SAFETY ISSUE AS THE HIGH-CENTER BRAKE LIGHT SERVES AN IMPORTANT FUNCTION AND AT $120 PLUS LABOR TO REPLACE IS CAN GET EXPENSIVE. *TR
