2004 CHEVROLET SUBURBAN Complaints

2004 CHEVY SUBURBAN SPEEDOMETER GOES CRAZY,SOMETIMES SET AT 120 MPH WHILE SETTING STILL. WHILE DRIVING I NEVER KNOW THE SPEED I'M GOING. ONE DAY MY WIFE WAS DRIVING THE SPEEDOMETER JUST KEPT CLIMBING TO 120 MPH , THAT IS WHEN IT STARTED. SOMETIMES THE SPEEDOMETER GOES DOWN TO 0 MPH THEN WHILE DRIVING SAY 30 MPH I GUESS IT MAY TAKE YOU TO 60 MPH, 80 MPH WHILE AT THE SAME RPM. NOTHING HAS BEEN DONE ,IT HAS 44000 MILES THEREFORE MY WARRANTY IS OUT I HAVE TO SEE IF THE EXT WARRANTY I GOT COVERS THIS, ALSO I HAVE BEEN CHECKING THE INTERNET IF ANYONE HAD SIMILAR PROBLEMS AND I HAVE FOUND NUMEROUS PEOPLE ON TOPIX.NET . THANK YOU FOR YOU'RE TIME. *NM

2004 CHEVROLET SUBURBAN - SPEEDOMETER NOT WORKING PROPERLY. DOES NOT GIVE THE RIGHT SPEED. MAY BE GOING 30 BUT SAYS 70 AND VICE VERSA. *NM

SPEEDOMETER DOES NOT WORK PROPERLY ON 2004 CHEVY Z71 TAHOE. IT IS EITHER PEGGED AT 120 MPH, READS TOO HIGH , OR READS TOO LOW. *JB

LAST NIGHT THE SPEEDOMETER STARTED TICKING LOUDLY AND MOVING WITH SUDDEN JERKING MOVEMENTS. IT THEN SHOWED I WAS GOING 85 MPH WHEN I WAS ACTUALLY GOING LESS THAN 45. THIS GOT PROGRESSIVELY WORSE AS I CONTINUED, TO THE POINT IT SHOWED I WAS GOING OVER 120 MPH WHEN STOPPED. NOW IT IS ALL THE WAY TO FAR RIGHT SIDE AND IS STUCK. IT WILL NOT RESET WHEN THE VEHICLE IS TURNED OFF. *NM

DT*: THE CONTACT STATED WHILE TRAVELING 5 MPH, THE POWER STEERING FAILED, THEN BOTH FEET WERE USED TO STOP THE VEHICLE. IT WAS TAKEN TO AN INDEPENDENT REPAIR SHOP WHO DETERMINED THE POWER STEERING AND BRAKE BOOSTER SYSTEM FAILED AND BOTH COMPONENTS WERE REPLACED.

ON MY 2004 CHEVY SUBURBAN THE HOUSING UNIT FOR THE SPARE TIRE WILL NOT RELEASE THE SPARE TIRE TO COME DOWN, SO YOU CAN FIX A FLAT. I BELIEVE THIS IS A SAFETY ISSUE BECAUSE IF YOU CAN'T GET THE SPARE TIRE DOWN, YOU CAN'T CHANGE THE FLAT--& YOU WILL BE STUCK ON THE HIGHWAY WITH CHILDREN--WE HAD NEVER USED THE SPARE TIRE BEFORE--BUT WHEN WE NEEDED IT, IT WAS INOPERABLE. *NM

6-2006, 98 DEGREES, CENTENNIAL, COLORADO 2004 CHEVY 8.1 LITER SUBURBAN, DRIVING 55-60 MPH FOR APPROX. 1 HOUR(NO TRAILER) VEHICLE SUDDENLY LOSS POWER, I HAD TO PULL OVER AND HAVE VEHICLE TOWED TO CHEVY DEALER. (DEALER STATED CODES INDICATED MISFIRING) FURTHER TESTING, SERVICE WAS ABLE TO DUPLICATE ISSUE AND LOCATE A BULLETIN OUTLINING THE PROBLEM. PER DEALER, FAULTY FUEL PUMP, GM ADVISED TO SWITCH FUEL PUMP TO A HIGH ALTITUDE PUMP, TO REMEDY THE ISSUE. WHICH WAS DONE, AND IT FIXED THE ISSUE. AS THE 8.1 LITER SUBURBAN IS A VEH. PRIMARILY USED FOR TOWING, THIS NEEDS TO BE A RECALL OR CAMPAIGN TO WARN PEOPLE. THIS SUDDEN LOSS OF POWER AND CONTROL COULD BE CATASTROPHIC IN NATURE. *NM

DT*: THE CONTACT STATED WHILE TRAVELING AT VARIOUS SPEEDS, THE REDUCED ENGINE POWER ALARM RINGS AND THE ENGINE IMMEDIATELY LOSES POWER. THE POWER RETURNS AFTER THE VEHICLE IS TURNED OFF AND BACK ON. THE DEALERSHIP REWIRED THE VEHICLE, REPLACED THE MODULATOR, SENSOR AND RELAY. THESE ATTEMPTS HAVE NOT REPAIRED THE PROBLEM.

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
