2004 CHEVROLET IMPALA Complaints

I HAVE NOTICED THAT FOR THE PAST FEW WEEKS, WHENEVER THE TEMPERATURE IS BELOW 20 DEGREES, THE SPEEDOMETER ACTS FUNNY. THE SPEEDOMETER READS ANYWHERE FROM 25 TO 80 MILES FASTER THAN MY ACTUAL SPEED; TODAY, I WASN'T GOING ANY MORE THAN 30MPH AT THE MOST, AND THE SPEEDOMETER NEEDLE WAS POINTING DIRECTLY DOWN TO THE CAR FLOOR. A FEW PEOPLE ON A COUPLE OF MESSAGE BOARDS SUGGESTED TURNING THE IGNITION KEY TO 'ACCESSORIES' ON AND OFF RAPIDLY SEVERAL TIMES, BUT ALL IT DID WAS BRING THE SPEEDOMETER DOWN FROM 85 TO 70. *TR

2004 CHEVY IMPALA SPEEDOMETER ERRATIC,MAY SHOW 85MPH WHEN TRAVELING 50-55MPH,OR 40MPH WHEN TRAVELING 70MPH. WHEN PROBLEM OCCURS YOU CAN RE-ZERO THE SPEEDOMETER BY TURNING THE IGNITION SWITCH ON AND OFF A NUMBER OF TIMES TO GET THE NEEDLE BACK TO ZERO, BECAUSE WITH POWER OFF THE NEEDLE IS USUALLY FROM 35-40MPH INDICATION TO BELOW ZERO INDICATION. COLD WEATHER SEEMS TO MAKE IT NOT WORK AT ALL UNTIL THE VEHICLE WARMS UP INSIDE THE CAR. I HAVE A CASE FILE WITH CHEVROLET FOR MONETARY HELP,BUT I ALSO BELIEVE THIS IS A SAFETY ISSUE. THANK YOU! *TR

I HAVE A 2004 CHEVY IMPALA THAT HAS A MALFUNCTIONING SPEEDOMETER. IT WILL READ I AM GOING 140 MPH WHEN I AM ONLY GOING 20 MPH. SOMETIMES IT GOES THE OTHER WAY AND IT WILL READ 0 MPH WHEN I AM GOING 55 MPH. I HAVE READ OF SIMILAR COMPLAINTS WITH THE SAME MAKE AND MODEL. I THINK IT IS A DEFECT THAT NEEDS A RECALL. THIS COULD BE A REAL SAFETY ISSUE WITH NOT KNOWING THE CORRECT SPEED IN WHICH YOU ARE TRAVELING. *TR

SPEEDOMETER READS INTERMITTENTLY. SOMETIMES IT COMES BACK ON AND READS FOR AWHILE, OTHER TIMES NO READING AT ALL AND STILL OTHER TIMES READS LOW OR HIGH....CAR IS 4 YEARS OLD HAS 60-70 K MILES. SPEEDING VIOLATION AND DISTRACTION WHILE DRIVING. *TR

SPEEDOMETER AND FUEL GAUGE WENT OUT UNEXPECTEDLY AT AROUND 45000 MILES IN JULY. FUEL GAUGE DOESN'T WORK AT ALL (BELOW E ALL THE TIME) AND SPEEDOMETER READS INCORRECT READINGS OR JUST STAYS BELOW 0. I HAD IT "DIAGNOSED" AT A CHEVY DEALER SO I COULD CALL CHEVY AND COMPLAIN. THEY SAID THEY WOULDN'T FIX IT, AND THE PROJECTED COST WAS $400. THIS IS GM'S FAULT AND I SHOULD NOT HAVE TO PAY OUT-OF-POCKET TO FIX THEIR MISTAKES. *TR

ELECTRICAL SYSTEM: INSTRUMENT PANEL I JUST PURCHASED A 2004 IMPALA WITH 97K ON IT AND WHILE DRIVING HOME AT 65-70 MPH IT STATED I WAS GOING 110-130. IT CREATED A VERY DANGEROUS DRIVING CONDITION BECAUSE THEIR WAS LIGHT TRAFFIC AND IT IS VERY DISTRACTING. I WAS UNABLE TO DETERMINE MY SPEED THE ENTIRE TIME. I BELIEVE THIS COULD BE THE CAUSE OF AN ACCIDENT BECAUSE IF THIS PROBLEM HAPPENS WHEN YOU ARE GOING SLOWER THAT IT STATES WHAT IF IT HAPPENS WHEN YOU ARE GOING FASTER. SERIOUS POTENTIAL TO CAUSE ACCIDENTS BECAUSE IT HAPPENS RANDOMLY AND DOES NOT GO AWAY. *TR

THIS IS AN ON-GOING PROBLEM THAT STARTED IN MID MAY, 2008. MY SECURITY LIGHT COMES ON AND THEN A WHILE LATER, MY CAR WON'T START FOR AN EXTENDED PERIOD OF TIME.... I HAVE HAD THIS TO THE CHEVROLET DEALER 3 TIMES AND HAVE REPLACED THE IGNITION SWITCH AND THE BODY CONTROL MODULE. THEY ARE AT A LOSS OF WHAT TO DO NEXT. I HAVE HEARD SIMILAR COMPLAINTS WITH THE IMPALA - AND NO REMEDIES. *TR

WHEN DRIVING AT NORMAL SPEED ON INTERSTATE HIGHWAY, SPEEDOMETER KEEPS INCREASING WITHOUT INCREASING SPEED, UNTIL NEEDLE GOES ALL THE WAY TO BOTTOM OF DIAL, WHICH WOULD BE ABOUT 150 MPH. IF VEHICLE IS NOT DRIVEN FOR A DAY OR SO, IT WILL RETURN TO NORMAL, BUT GOES CRAZY AGAIN, AND IMPOSSIBLE TO KNOW CORRECT SPEED. DEALER HAD REPLACED MANY SPEEDOMETERS ON PICKUPS AND SUVS, BUT WILL NOT COVER THIS UNDER WARRANTY OR RECALL. THIS HAS HAPPENED TO MANY OWNERS, SEE BLOGS!! *TR

THE SPEEDOMETER ON MY 2004 IMPALA DOES NOT WORK. SHOULD BE CONSIDERED A MAJOR SAFETY HAZARD. DEALER ESTIMATE TO REPAIR 500.00-700.00. GM DOES NOT RESPOND. FROM INTERNET RESEARCH THERE ARE THOUSANDS OF THIS YEAR VEHICLE WITH THIS PROBLEM, WHY NO RECALL?? *TR

THE GAUGE THAT TELLS THE SPEED DOES NOT WORK. EVERYTIME I AM USING THE CAR IT GETS STUCK AND THE ONLY WAY TO CORRECT THE ISSUE IS BY TURNING THE CAR ON AND OFF. I AM SORRY, BUT THIS IS AN EXTREME SAFETY ISSUE. I HAVE NO CLUE HOW FAST I AM GOING OR HOW SLOW I AM GOING WHICH COULD LEAD TO A MAJOR CAR ACCIDENT. *TR
