2004 Chevrolet Suburban

FUEL PUMP SEIZES WHEN IN HOT CLIMATES OR WHEN TOWING A TRAILER. GM REPLACED THE FUEL PUMP LAST YEAR AND IT APPEARED TO SOLVE THE PROBLEM. BUT, THE PROBLEM OCCURRED AGAIN WHILE PULLING A TRAILER UP AND DOWN A STEEP MOUNTAIN PASS RESULTING IN A LOSS OF BRAKES AND STEERING WHEN THE ENGINE STALLED. THIS OCCURS WHEN THE FUEL TANK IS AT 1/4 FULL OR LESS. THE TRAILERING FUEL ADVANCE DELIVERS FUEL TO THE ENGINE AND IF NOT NEEDED THEN IT IS RETURNED TO THE TANK AND RECIRCULATION. THE FUEL IS WARM WHEN RETURNED TO THE TANK. THE LONGER THE ENGINE RUNS THE HOTTER THE FUEL BECOMES AND WHEN THE FUEL IN THE TANK BECOMES HOT ENOUGH THE FUEL PUMP, WHICH IS LOCATED IN THE FUEL TANK THEN SEIZES AND THE ENGINE STALLS. THIS IS A MAJOR SAFETY HAZARD, PARTICULARLY WHEN TRAILERING IN THE MOUNTAINS AND THE LOSS OF BRAKES AND STEERING OCCURS. THE ONLY SOLUTION WHEN THIS OCCURS IS TO PULL TO THE SIDE OF THE ROAD IF POSSIBLE, RAISE THE HOOD AND LET THE VEHICLE COOL FOR 15-20 MINUTES AND THEN START AGAIN. OR, FIND THE NEAREST GAS STATION AND FILL THE TANK WITH COOL GASOLINE SO THE FUEL PUMP NO LONGER SEIZES. IN THE CASE OF BREAKING DOWN ON THE SIDE OF THE ROAD, THIS IS ANOTHER MAJOR SAFETY HAZARD SINCE THIS PROBLEM OCCURS BOTH GOING UP OR DOWN HILLS AND THERE IS A LOSS OF STEERING AND BRAKES. THIS MEANS THE VEHICLE IS OFTEN IN TRAFFIC AND MAY RESULT IN AN ACCIDENT.*JB

DT*: THE CONTACT STATED WHILE DRIVING AT SPEEDS BETWEEN 5 AND 45 MPH THE VEHICLE STALLED ON 6 OCCASIONS. THE VEHICLE WOULD NOT RESTART AND HAD TO BE TOWED TO THE DEALER EACH TIME. THIS PROBLEM STARTED IN AUGUST 2005. ON 5 OCCASIONS THE DEALER COULD NOT DUPLICATE THE PROBLEM HOWEVER; ADJUSTMENTS WERE MADE TO THE VEHICLE. ON THE SIXTH OCCASION THE DEALER REPLACED THE PCM MODULE.

DT*: THE CONTACT STATED THE VEHICLE SPEEDOMETER DISPLAYED AN INCORRECT READING ON THE DASH PANEL GAUGE. THE INCORRECT DISPLAY WAS CONSTANT AND FAVORED NO PARTICULAR SPEED. HOWEVER THE MOST COMMON EVIDENCE OF THIS PROBLEM WAS WHILE DRIVING AT A LOW SPEED THE GAUGE DISPLAYED AN OUTRAGEOUSLY HIGH SPEED. THE DEALER AND MANUFACTURER HAVE BEEN CONTACTED. *AK

HAD STARTING PROBLEMS WITH MY SUV. TOWED TO DEALER, WHERE I WAS TOLD THAT THE FUEL PUMP WENT BAD DUE TO A CLOGGED FUEL FILTER. CALLED TO COMPLAIN TO GM THAT THE REQUIREMENT TO REPLACE THE FUEL FILTER WAS NOT LISTED ON THEIR SCHEDULED MAINTENANCE CHART IN THE OWNER'S MANUAL, I WAS THEN TOLD THAT THE PUMP SHORTED OUT WHICH CAUSED THE FAILURE. THIS IS AN INTERNAL FUEL PUMP MOUNTED WITHIN THE TANK ITSELF. *JB

2004 CHEVY SUBURBAN EXHAUST SYSTEM PRODUCES NOISE AT IDLE ;DRIVING;AND AFTER SHUT DOWN. GM CLAIMS NOISE (POPPING) IS FROM MUFFLER HEAT SHIELD EXPANSION AND CONTRACTION. TSB TO CORRECT NOISE (MODIFYING HEAT SHIELD) IS INEFFECTIVE. IN 2004 MOTOR MAGAZINE REPORTED GM ACKNOWLEDGED THE NOISE CAME FROM TRAPPED WATER INSIDE THE MUFFLER. THE WATER TURNS TO SUPER HEATED STEAM AND PRODUCES A POP OR BANG INSIDE THE MUFFLER. GM WILL NOT REPLACE THE MUFFLER AS THE PROBLEM GOES BACK TO 2000 MODEL YEAR. MOREOVER PEOPLE ASK WHAT THAT STRANGE NOISE IS FROM MY SUBURBAN, I TELL THEM A DEFECTIVE MUFFLER. *JB
