2003 CHEVROLET SUBURBAN Complaints

WHILE SLOWING FROM 55MPH TO MAKE A TURN OFF OF STATE HIGHWAY, BRAKE SYSTEM FAILED AT APPROXIMATELY 35MPH DUE TO RUPTURED STEEL LINE. PEDAL WENT FULLY TO FLOOR, BRAKES RELEASED AND TURN OFF WAS MISSED. THANKFUL NOBODY WAS IN THE WAY! SHOCKED THAT THIS IS APPARENTLY A COMMON ISSUE WITH THIS VEHICLE AT JUST 13YRS AND 150K MILES!!

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.

VEHICLE SUDDENLY STARTED GOING INTO REDUCED POWER MODE AND PROVIDING AN ERROR CODE INDICATING A PROBLEM WITH THE THROTTLE CONTROL SENSOR. FROM THE HUNDREDS OF ONLINE POSTS (SOME BY GM MECHANICS) THIS IS AN ONGOING PROBLEM WITH MANY 2003-2008 TRUCKS AND SUVS MADE BY GM. WHEN I BEGAN TRYING TO REPAIR THIS PROBLEM MYSELF, I FOUND OUT FROM MY LOCAL CHEVY PARTS DEPARTMENT THAT "THEY CAN NOT KEEP THESE THROTTLE CONTROL ASSEMBLIES IN STOCK BECAUSE WE ARE REPLACING SO MANY OF THEM..." THERE SEEMS TO BE A KNOW PROBLEM THAT GM IS NOT ADEQUATELY BEING PROACTIVE ABOUT. THIS HAPPENS WHILE DRIVING HIGHWAY, LOCAL STREETS AND AT STARTUP. THIS BECOMES A SERIOUS SAFETY ISSUE WHEN THE VEHICLE GOES INTO REDUCED POWER MODE WHILE THE VEHICLE IS IN TRAFFIC.

THE RED BRAKE LIGHT IS ON. THE ABS MODULE IS NOT ALLOWING THE TWO REAR BRAKES TO WORK. THE A/C CONTROL BOX IN THE DASH BLOWS HOT AIR THROUGH THE DRIVER SIDE ONLY. IN FL THAT IS DANGEROUS BECAUSE OF THE HEAT ALREADY.

IT'S MAKE A WEIRD SOUND WHEN TURNING THE ABS INDICATOR LIGHT IS ON THER DASH STATIONARY I CAME OUTSIDE TO START UP THE VEHICLE IS NOTICED A LIQUID LEAKING FROM UNDERNEATH

WHILE DRIVING WITH MY TWO DAUGHTERS AND HUSBAND, WE ATTEMPTED TO COME TO A STOP AND BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR, TRUCK WOULD NOT STOP. LUCKILY WE WERE NOT GOING THAT FAST JUST 20 MPH. HUSBAND DIAGNOSED THE PROBLEM, NO BRAKE FLUID. DROVE VERY SLOWLY TO LOCAL AUTO STORE, FILLED UP BRAKE FLUID. NO CHANGE IN BRAKES. WAS ABLE TO DRIVE SLOWLY HOME WITH HAZARDS ON. TOOK TO LOCAL MECHANIC, UPON INSPECTION, BRAKES LINES COMPLETELY RUSTED OUT! ENTIRE BRAKE LINE TO BE REPLACED, OVER 2000.00 JOB!

I WILL BE DRIVING DOWN THE ROAD BOTH HWY AND CITY. THE SUBURBAN WILL GO INTO REDUCED ENGIN AND LOSE ALL ITS POWER AND SPEED. I HAVE TO PULL OVER AND CUT THE CAR OFF AND RESTART IT AND IT'S FINE TO GO FOR MAYBE A MILE AND IT DOES IT AGAIN. THEY CAN NOT PIN POINT WHAT THE PROBLEM IS . IT'S VERY DANGEROUS.

WHILE APPLYING MY BRAKES ON HIGHWAY ROUT 87, NEAR ALBANY NY, THE PEDAL WENT TO THE FLOOR AND WE CRASHED INTO THE CAR IN FRONT OF US. AFTER BEING TOWED TO A AAA REPAIR FACILITY THEY TOLD US THAT THE BRAKES WERE FINE BUT THE STEEL BRAKE LINE HAD BLOWN OUT AND THE FLUID HAD LEAKED CAUSING LOSS OF STOPING POWER WITHOUT ANY WARNING... WE SPENT $890.00 PLUS A HOTEL ROOM FOR ONE NIGHT AS WE WAITED FOR THEM TO MAKE A REPAIR TO ONE BRAKE LINE. I RECENTLY FOUND OUT ALL THE BRAKE LINES ARE ROTTED OUT AND NEED TO BE REPLACED. THIS MAKES NO SENSE.....THERE IS A CLEAR SAFETY ISSUE HERE. PLEASE REOPEN THE CASE AND ADVISE A RECALL BEFORE A BIG SUV LIKE OURS HURTS SOMEONE IN A SMALL CAR BECAUSE THERE BRAKE LINES FAILED. THEY WON'T KNOW UNTIL ITS TO LATE!!!

THE REAR DRIVERS SIDE BRAKE LINE BROKE. WHILE AT THE REPAIR SHOP, THEY INFORMED ME THE OTHER SIDE BRAKE LINE WAS BAD AND NEEDED REPLACED. TWO MONTHS LATER TWO MORE LINES BROKE. THE MAIN REAR LINE AND FRONT SUPPLY LINE FROM THE MASTER.

TL* THE CONTACT OWNS A 2003 CHEVROLET SUBURBAN 2500. WHILE DRIVING 35 MPH, THE CONTACT DEPRESSED THE BRAKE PEDAL AND IT TRAVELED ALL THE WAY TO THE FLOORBOARD. THE CONTACT WAS ABLE TO STOP THE VEHICLE. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE THEY PERFORMED AN INTERIM REPAIR. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT ALL THE BRAKE LINES WERE RUSTED AND NEEDED TO BE REPLACED. THE CONTACT WAS ALSO INFORMED BY THE INDEPENDENT MECHANIC THAT THE VEHICLE MAY NEED THE FUEL PUMP LINE REPLACED AS WELL. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 72,000.
