2004 CHEVROLET IMPALA Complaints

THE SPEEDOMETER DOESN'T WORK SOMETIMES. WHEN IT MOVES IT DOESN'T MOVE SMOOTHLY, BUT IT JERKS UP AND DOWN, OFTEN INDICATING AN INCORRECT SPEED. THE CAR HAS LOW MILES ON IT AND THE TCC SOLENOID AND ANOTHER SOLENOID REGULATING LINE PRESSURE IN THE TRANSMISSION HAS FAILED, REQUIRING REPLACEMENT. *TR

FAILURE: LOWER INTAKE GASKET FAILED DUE TO DEXCOOL ANTIFREEZE. DEXCOOL INSTALLED AT FACTORY. VEHICLE HAD SUDDEN SERIOUS COOLANT LEAK . VEHICLE OVERHEATED ON HIGHWAY AND STRANDED OWNER. VEHICLE WAS TAKEN TO DEALER FOR SERVICE. DEALER TOLD OWNER TO REPLACE GASKET AND COOLANT. SERVICE TECHNICIAN REPLACED DEXCOOL WITH ANOTHER LONG LIFE BRAND OF ANTIFREEZE. THE ORIGINAL DEXCOOL ALSO CLOGGED THE RADIATOR WHICH REQUIRED EXTRA FLUSHING WITH ADDITIONAL CHEMICALS. *TR

THE SPEEDOMETER IN MY 2004 IMPALA DOES NOT FUNCTION PROPERLY. IT IS UNPREDICTABLE IN WHAT SPEED IT MEASURES. SOMETIMES IT STAYS ON "0" SOMETIMES IT'S AT "110" WHEN I'M DOING APPROX. 20MPH. IT'S JUST BROKEN. *TR

THE INSTRUMENT CLUSTER ON MY 2004 CHEVY IMPALA LS HAS STOPPED WORKING. ALSO, THE FUEL & OIL GAUGES DO NOT WORK. THE GAUGES STOPPED WORKING ABOUT 2 YEARS AGO AFTER WORKING WITHOUT PROBLEMS. FROM MY ONLINE SEARCHES, I'VE SEEN MANY OTHER IMPALA OWNERS WITH THE SAME PROBLEM. I HAVE NOT HAD THE CLUSTER REPLACED, BUT INSTEAD USE A HANDHELD GPS FOR SPEED. I DO FEEL CHEVY/GM KNOWINGLY MANUFACTURED A BAD COMPONENT AND SHOULD BE HELD LIABLE FOR REPAIRS OF THE STEP MOTORS THAT HAVE FAILED IN THESE CARS. *TR

SPEEDOMETER CONSISTENTLY READS INCORRECTLY AND/OR FREEZES IN PLACE. OCCURS DAILY, RARELY GIVES CORRECT READING. DEALER WANTS $69.95 TO EVALUATE AND REPAIR WILL BE $400-$500 IF IT IS WHAT THEY THINK IT IS. CAR HAS NOT BEEN IN ANY ACCIDENTS. COOLANT TEMPERATURE GAUGE HAS PERIODICALLY MALFUNCTIONED AS WELL: SHOWS HIGH TEMPS WHEN ENGINE IS NOT OVERHEATING. COOLANT LEVELS ARE NORMAL. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET IMPALA. WHILE DRIVING IN REVERSE OR ACCELERATING AT VARIOUS SPEEDS, THE CONTACT HEARD A LOUD NOISE. HE TOOK THE VEHICLE TO THE DEALER AND THEY FOUND THAT THE MOTOR MOUNT BOLT LOCKS WERE OPENED, WHICH MAY HAVE CAUSED THE ENGINE TO FAIL. THE DEALER TIGHTENED THE BOLTS. THE CONTACT WAS AWARE OF THE SAFETY RISK INVOLVED. THE CURRENT AND FAILURE MILEAGES WERE 77,000.

TL*THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT STATED THAT THE SPEEDOMETER WORKS INTERMITTENTLY AND DISPLAYS INACCURATE READINGS. HE TOOK THE VEHICLE TO THE DEALER AND THEY STATED THAT THE SPEEDOMETER MODULE NEEDED TO BE REPLACED AT A COST EXCEEDING $600. THE VEHICLE HAS NOT BEEN REPAIRED. THE MANUFACTURER DID NOT ASSIST BECAUSE THE VEHICLE EXCEEDED ITS WARRANTY BY THIRTY DAYS. THE VIN WAS UNKNOWN. THE FAILURE AND CURRENT MILEAGES WERE 31,000.

THE SPEEDOMETER IN MY CAR DOES NOT WORK CORRECTLY. THE CAR ONLY HAS 32000 MILES ON IT & GM WILL NOT FIX THE PROBLEM. I FEEL IT IS A SAFETY ISSUE BECAUSE YOU CAN NOT TELL HOW FAST YOU ARE GOING. THE SPEEDOMETER WILL BE STUCK AT 30MPH AND I CAN BE DOING 40 OR 50 MPH. *TR

THIS AM DURING MORNING TRAFFIC AND MY VEHICLE CUT OFF. THIS HAPPENED SEVERAL TIMES LEADING TO ME HAVING TO GET MY CAR TOWED TO A CHEVY DEALER. COME TO FIND OUT MY PASSLOCK SENSOR FAILED. *TR

THE SPEEDOMETER ON THE INSTRUMENT CLUSTER GOES HAYWIRE. IT STICKS WHEN DRIVING HIGHWAY SPEEDS, AND THEN REMAINS SHOWING A HIGH SPEED WHEN SLOWING DOWN. WHEN YOU THEN SPEED BACK UP, IT SHOWS SPEEDS UPWARDS OF 100 MPH EVEN WHEN DRIVING SLOWER THAN EXISTING TRAFFIC. IT WILL ONLY GET BACK TO 0 IF I TURN THE IGNITION OFF AND ON MANY TIMES. IT IS EXCEPTIONALLY DANGEROUS TO TRAVEL WITHOUT KNOWING THE CORRECT SPEED THAT YOU ARE TRAVELING. *TR
