2003 Chevrolet Silverado 1500 Hd

WHILE STOPPED AT AN INTERSECTION AT A RED LIGHT, THE VEHICLE STARTED TO CREEP FORWARD TOWARD PEOPLE IN THE CROSSWALK. DEPRESSING THE BRAKE PEDAL FURTHER RESULTED IN IT FADING, ENDING IN A FULLY DEPRESSED POSITION WITH NO MORE PEDAL TRAVEL AVAILABLE. THE VEHICLE CONTINUED TO ROLL FORWARD INTO THE CROSSWALK. PLACING THE TRANSMISSION IN NEUTRAL STOPPED VEHICLE MOVEMENT. AFTER STOPPING AND INSPECTING UNDER THE HOOD AND UNDER THE FRONT END OF VEHICLE SHOWED LEAKING BRAKE FLUID FROM ONE OF THE METALLIC BRAKE LINES SERVING THE RIGHT FRONT BRAKE. AFTER TAKING THE VEHICLE TO MY LOCAL GM DEALER AND PLACING IT ON THE SERVICE RACK, INSPECTION SHOWED THAT ALL THE METALLIC BRAKE LINES ARE SEVERELY RUSTED OVER THE MAJORITY OF THE LINE SURFACE. THE RIGHT FRONT LINE DISINTEGRATED TO THE POINT WHERE THE LINE SEPARATED WHILE CHECKING THE CONDITION OF THE LINE. THE OTHER BRAKES LINES ARE RUSTED TO THE POINT WHERE FAILURE IS IMMINENT. ALL THE METALLIC BRAKE LINES FROM THE MASTER CYLINDER, DOWN TO THE ABS CONTROL MODULE AND THEN OUT TO EACH BRAKE CALIPER MUST BE REPLACED. THE FAILURE OF THE BRAKING SYSTEM CREATED A SERIOUS SITUATION THAT COULD HAVE RESULTED IN BODILY INJURY TO THE PEDESTRIANS IN THE CROSSWALK. WITHOUT PLACING THE TRANSMISSION IN NEUTRAL IT WOULD HAVE EVENTUALLY STRUCK A PEDESTRIAN. IN ADDITION TO THE BRAKE LINES, THE FUEL LINES SHOW EXCESSIVE RUST AS WELL. THE DEALER DOES NOT RECOMMEND REPLACEMENT OF THE FUEL LINES AT THIS TIME, BUT REPLACEMENT WILL BE REQUIRED IN THE NEAR FUTURE. *TR

TL*THE CONTACT OWNS A 2003 CHEVROLET SILVERADO 1500 HD. THE CONTACT STATED THE FUEL GAUGE INTERMITTENTLY DISPLAYED IMPROPER READINGS OF EMPTY AND FULL. THE CONTACT ALSO STATED THE SPEEDOMETER INTERMITTENTLY DISPLAYED IMPROPER SPEED READINGS. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THE CONTACT WAS TOLD THE INSTRUMENT CLUSTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 75,000 AND THE CURRENT MILEAGE WAS 141,000.

WHILE DRIVING AT ANY SPEED, I HEAR A CHIME FROM THE INSTRUMENT PANEL, THEN NOTICE THAT THE VEHICLE CAN NO LONGER ACCELERATE. I ALSO NOTICE THAT THE ENGINE LIGHT IS ON, AND THERE IS A MESSAGE DISPLAYED STATING THE VEHICLE IS IN "LOW ENGINE POWER MODE". AT THIS POINT, THE VEHICLE CAN STILL BE DRIVEN BUT AT VERY LOW SPEED ONLY. ANY POWER FOR MANEUVERABILITY UNDER HEAVY TRAFFIC OR HIGHWAY CONDITIONS IS GONE. AFTER PULLING OVER TO THE SIDE OF THE ROAD AND SHUTTING OFF THE ENGINE, THE ENGINE LIGHT STAYS ON BUT THE ENGINE POWER MAY HAVE RETURNED TO NORMAL (FOR A WHILE). THE FOLLOWING DAY OR SO - THE ENGINE LIGHT MAY EVEN STAY OFF, AND EVERYTHING APPEARS NORMAL. WHEN THE PROBLEM IS FIRST NOTICED, IT SEEMS TO RECUR EVERY FEW DAYS. AS TIME GOES ON HOWEVER (MAYBE 2 WEEKS) THE PROBLEM HAPPENS MORE FREQUENTLY AND IS LESS APT TO "RESET" JUST BY TURNING OFF THE ENGINE. THE FIRST TIME I TOOK THE VEHICLE INTO THE DEALER, THEY REPLACED THE THROTTLE CONTROL SENSOR CONNECTOR, FOR A TOTAL BILL OF ABOUT $350. NOW, AFTER ONLY 10 MONTH, THE PROBLEM HAS RECURRED. I TOOK IT BACK TO THE DEALER YESTERDAY, AFTER ONLY TWO OF THESE "EVENTS" WITHIN ONE WEEK, AND WAS CHARGED ANOTHER $535 TO HAVE THE THROTTLE BODY REPLACED ("FAULTY SENSORS WITHIN THE BODY"). LAST NIGHT THE PROBLEM CAME BACK AGAIN (YES - SAME DAY!). TODAY THE DEALER ADDED A "REDUNDANT" GROUND TO THE THROTTLE BODY (NO CHARGE THIS TIME). I WAS TOLD BY THE MECHANIC THAT THIS PROBLEM HAS SHOWN UP ON MANY VEHICLES LIKE MINE, AND THAT GM SEEMS TO BE AT A LOSS AS TO WHAT IS CAUSING THE PROBLEM. THIS IS AN ELECTRONIC THROTTLE CONTROL (NO DIRECT LINKAGE BETWEEN GAS PEDAL AND CARBURETOR). I AM THANKFUL THAT GM DESIGNED THIS TO FAIL WITH POWER LOSS RATHER THAN FULL POWER (TOYOTA), BUT I BELIEVE THIS IS A SAFETY CONCERN NONE THE LESS. GM IS OBVIOUSLY AWARE OF THE PROBLEM BUT IS DOING NOTHING TO REPAIR AN OBVIOUS DESIGN FLAW IN THEIR PRODUCT. *TR
