2004 CHEVROLET IMPALA Complaints

SPEEDOMETER WILL GIVE ERRADIC READINGS. I FIRST NOTICED IT ON DECEMBER 22 WHILE DRIVING DOWN THE HIGHWAY; SPEEDOMETER SUDDENLY BEGAN TO READ 110 MPH. AT A STANDSTILL, SPEEDOMETER WAS READING 50 MPH. IT HAS DONE THIS ON TWO MORE OCCASIONS, WITH THE LAST DATE BEING JANUARY 4, 2008. I HAVE BEEN ABLE TO GET THE SPEEDOMETER BACK TO ZERO WHILE BEING PARKED, BUT I WOULD HAVE TO TURN THE VEHICLE OFF AND THEN TURN THE IGNITION TO "ACC". EACH TIME I DID THIS, THE SPEEDOMETER WOULD GO DOWN APPROX. 5 MPH SO I CONTINUED TO DO THIS UNTIL THE SPEEDOMETER READ ZERO AGAIN. I HAVE BEEN TOLD IT IS PROBABLY A SENSOR ISSUE AND WHEN I DID RESEARCH, I FOUND 40 ADDTIONAL COMPLAINTS OVER THE SAME THING AND WAS READING ABOUT A POTENTIAL CLASS-ACTION LAWSUIT IN SEATTLE DUE TO SPEEDOMETER FAILURES. *CN

2004 CHEVROLET IMPALA. HEADLIGHTS SUDDENLY STOPPED WORKING COMPLETELY WHILE BACKING OUT OF MY DRIVEWAY ONTO MY ROAD. WHILE I WAS ABLE TO PULL BACK INTO MY DRIVEWAY QUICKLY, IT WOULD HAVE BEEN ANOTHER STORY A MINUTE LATER WHEN I WOULD HAVE BEEN AT A BUSY INTERSECTION. BECAUSE THERE WAS NO ACCIDENT OR INJURIES, DOES NOT MAKE THIS ANY LESS OF A SERIOUS SAFETY RELATED FAILURE OF THIS VEHICLE. IF THE POLICE CAN TICKET YOU FOR NOT FIXING ONE HEADLIGHT WHEN IT FAILS, WHY WOULD THIS NOT BE A MORE SERIOUS SAFETY PROBLEM? I HAD THE VEHICLE IN TO THE GM DEALERSHIP WHERE THEY DETERMINED THAT THE MULTIFUNCTION SWITCH (ON THE STEERING COLUMN) HAD FAILED. IT WAS REPLACED AND IT COST ME $786.00 CANADIAN. MY WIFE TOLD ME THAT THE LIGHTS HAD GONE OUT A FEW WEEKS PRIOR TO THIS WHILE DRIVING HOME ONE NIGHT. THEY SUDDENLY WENT OUT FOR A FEW SECONDS AND THEN CAME BACK ON BY THEMSELVES. I AM ASSUMING THIS WAS CAUSED BY THE SAME MALFUNCTION.*CN

INSTRUMENT CLUSTER FAILURE CAUSING SPEEDOMETER TO SHOW INACCURATE READINGS AND/OR BECOME COMPLETELY INOPERATIVE. OTHER GAUGES ALSO REGISTER INACCURATE READING.*CN

MY WIFE AND I OWN A 2004 CHEVY IMPALA WHICH WE BOUGHT NEW FROM GM. THE CAR HAS 43756 MILES ON IT, AND THE SPEEDOMETER HAS COMPLETELY QUIT WORKING. IT CURRENTLY READS 107 MPH EVEN WHEN THE CAR IS TURNED OFF. THE OTHER GAUGES STARTED ACTING STRANGE, BUT WHEN THE KEY IS CYCLED, THEY GO BACK. HOWEVER, THE SPEEDOMETER DOES NOT BUDGE. THIS STARTED THE DAY BEFORE CHRISTMAS, AND HAS CONTINUED EVER SINCE.*CN

2004 IMPALA LS, SPEEDODMETER ERRATIC THEN JUST FAILED. IN PARK I AM GOING APPROX 160 MPH. CONTACTED GM TO TRY AND GET IT COVERED, THE SAID NO. IN TIME CAR HAS NOW GONE OVER 70K MILES. WILL HAVE TO FIX ON MY DIME ( APPROX $700). MANY OTHER 2004 GM TYPES ALL HAVING THE SAME ISSUE. SERVICE DEPT AGREES AND HAD 2 OTHER 2004 IMPALA'S IN SHOP FOR THE SAME FAILURE. *TR

NORMAL DRIVING, SPEEDOMETER GOES TO 120MPH AND STAYS THERE. I STOPPED THE CAR AND SHUT IT OFF. TURNED IT BACK ON. STILL AT 120 MPH. CALLED THE LOCAL CHEVY DEALER AND THEY SAID THEY NEVER HEARD OF SUCH A THING. I CHECKED THE WEB AND FIND ITS A COMMON PROBLEM EVEN THOUGH CHEVY WILL NOT ACKNOWLEDGE THE ISSUE. DANGEROUS DRIVING WITHOUT A WORKING SPEEDOMETER! *TR

WHILE TRAVELING ON THE OHIO TURNPIKE SPEEDOMETER SUDDENLY STARTED CLIMBING HIGHER AND EVENTUALLY PEGGED ITS SELF. I STOPPED VEHICLE AT THE NEXT PLAZA AND TURNED ENGINE OFF. SPEEDOMETER REMAINED PEGGED WITH ENGINE OFF. I GOT HOME AND PARKED CAR. THE FOLLOWING MORNING SPEEDOMETER WAS STILL PEGGED. BY TURNING IGNITION SWITCH ON AND OFF I WAS ABLE TO BACK UP NEEDLE TO 0 POSITION. SPEEDOMETER WORKED ALRIGHT AT LOWER CITY SPEEDS UNTIL ON 12-25-07 I AGAIN GOT ON THE OHIO TURNPIKE TO GO TO MICHIGAN. AGAIN THE SPEEDOMETER STARTED CLIMBING AND WAS WELL PAST 120 MPH MARK WHEN I REACHED MY DESTINATION . AGAIN I WAS ABLE TO RESET SPEEDOMETER BY TURNING KEY OFF AND ON. RETURNING TO OHIO ON I75 AGAIN THE SPEEDOMETER STARTED CLIMBING AND WHEN I GOT HOME SPEEDOMETER WAS AT 120. AT THIS POINT I TOOK SEVERAL DIGITAL L PHOTOGRAPHS OF NEEDLE POSITION AND WILL LEAVE IT THERE UNTIL I TAKE VEHICLE TO LOCAL CHEVROLET CAR DEALERSHIP TO SEE WHAT THE OUTCOME WILL BE. VEHICLE NOW ONLY HAS 23,900 MILES ON IT. *TR

2004 CHEVROLET IMPALA LS WITH APPROX 82,000 MILES. NOTICED TWO WEEKS AGO THAT THE SPEEDOMETER GAUGE IS NOT WORKING PROPERLY. IT WILL GO FROM 20 TO 120 WITH THE ACTUAL SPEED NOT CHANGING. VERY DANGEROUS ON THE HIGHWAY AND WITH OUR ICE AND SNOW. I HAVE NO IDEA HOW FAST I AM ACTUALLY GOING. I HAVE READ ABOUT SEVERAL OTHER INDIVIDUALS HAVING THIS EXACT SAME PROBLEM WITH THE 2004 IMPALA'S. THERE IS NO RECALL TO FIX THE PROBLEM, AND THE GM DEALERS WANT APPROXIMATELY $400 DOLLARS TO FIX THIS. THIS IS A VERY SERIOUS PROBLEM, AND I BELIEVE THAT AN INVESTIGATION SHOULD BE DONE ON THE 2004 IMPALA TO SHOW THIS IS A COMMON PROBLEM THAT GM SHOULD TAKE RESPONSIBILITY FOR. *TR

2004 CHEVROLET IMPALA SPEEDOMETER CLUSTER DOES NOT REGISTER THE CORRECT SPEED. IT MAY INDICATE OVER 100 + WHEN OTHER CARS ARE PASSING. SPEED MAY INDICATE OVER 100 WHEN CAR IS PARKED AND KEY IS REMOVED FROM IGNITION. *TR

WAS DRIVING NORMALLY AND THE SPEEDOMETER NEEDLE DROPPED FROM THE 12 O'CLOCK POSITION TO THE 6 O'CLOCK POSITION. IT NOW OPERATES SPORADICALLY AND IS USUALLY 10-15 MILES OFF. WORKING ON GETTING THE PROBLEM REPAIRED. *TR
