2005 Chevrolet Impala

I HAVE A 2005 CHEVY IMPALA.. FOR PAST TWO WEEKS MY SPEEDOMETER HAS BEEN READING INCORRECTLY. I WAS ON THE INTERSTATE DOING 70 MPH BUT IT FELT MORE LIKE 50. THE PROBLEM STOPPED FOR A COUPLE OF DAYS BUT YESTERDAY.. IT TOOK ANOTHER TURN. I WAS DOING 35MPH BUT THE READING SHOWED 0MPH. IT IS NOW POINTING IN THE UP AND DOWN POSITION AND WILL NOT MOVE. I HAVE CHECKED OTHER FORUMS AND FOUND THAT THERE ARE MANY MANY OTHER IMPALA OWNERS EXPERIENCING THE SAME PROBLEM. THIS SEEMS TO ME TO BE A FACTORY DEFAULT. THERE IS A MAJOR POSSIBILITY FOR SERIOUS ACCIDENTS OCCURRING DUE TO THIS PROBLEM . *TR

I OWN A 2005 CHEVROLET IMPALA WITH APPROX. 86,000 MILES ON IT. MY SPEEDOMETER IS GOING HAYWIRE(NOT CONSISTENT AT ALL) AND I AM UNABLE TO CORRECTLY TELL MY SPEED. I KNOW THERE ARE QUITE A BIT OF OTHER GM VEHICLES WITH THE SAME ISSUE BECAUSE THERE IS A BLOG ON THE INTERNET ABOUT THEM. I AM CONCERNED ABOUT THIS DUE TO THE FACT THAT I HAVE A 3 YEAR OLD SON AND MY WIFE WITH ME A LOT. GM SAID THEY WILL NOT PAY FOR THIS PROBLEM TO BE FIXED AND A LOT OF PEOPLE CAN NOT AFFORD IT($500-$800). I JUST HOPE GM WILL TAKE RESPONSIBILITY AND FIX THIS ISSUE AT FREE OF CHARGE TO THE CONSUMER BEFORE SOMEONE GETS INJURED OR EVEN KILLED. *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET IMPALA. SPORADICALLY, THE SPEEDOMETER ON THE INSTRUMENT CONTROL PANEL BECOMES INOPERATIVE AND DISPLAYS INACCURATE READINGS. AS A CONSEQUENCE, THE CONTACT CANNOT ACCURATELY MEASURE THE SPEED SHE IS DRIVING. THERE IS ALSO A STRONG FUEL ODOR EMANATING FROM THE VEHICLE. SHE TOOK THE VEHICLE TO A REPAIR SHOP, BUT THE FAILURE COULD NOT BE DUPLICATED OR REMEDIED. THE VEHICLE HAS NOT BEEN PROPERLY REPAIRED. THE FAILURE MILEAGE WAS 100,000 AND CURRENT MILEAGE WAS 116,000.

TEMPERATURE GAGE IS WORKING ONLY PART TIME, WILL INCREASE ABRUPTLY AND THEN DEGREE JUST AS FAST. LAST WEEK THE SPEEDOMETER CONTINUED TO INCREASE PAST THE NUMBERS THEN DECREASED SLOWLY THROUGHOUT THE DAY. I FILLED UP WITH GAS AND THE SPEEDOMETER STARTED WORKING AGAIN BUT THE TEMPERATURE GAGE FLOATED BACK AND FORTH. THIS WEEK THE SPEEDOMETER IS ON 90 WHEN THE CAR IS OFF. FILLED UP WITH GAS AGAIN HOPING IT WOULD CORRECT THE SPEEDOMETER AGAIN. INSTEAD THE SPEEDOMETER DROPPED TO THE N POSITION AT THE BOTTOM AND WILL MOVE TO 120 OCCASIONALLY. TOOK THE CAR TO REPAIR SHOP, HAD THE SENSOR CHECKED. SENSOR IS FINE. WAS TOLD MANY HAVE HAD THIS PROBLEM AND IS A DEFECT WITH THE CLUSTER THAT GM WILL NOT RECOGNIZE. THIS PROBLEM NEEDS TO BE ADDRESSED. THIS IS A REAL SAFETY ISSUE. *TR

THE SPEEDOMETER GETS STUCK YOU WILL BE ON THE HIGHWAY DOING 65 AND WHEN YOU GET OFF TO STOP IT WILL SAY THAT YOU ARE GOING 65 WHILE YOU ARE SITTING STILL OR IT WILL NOT MOVE AT ALL IT WILL SAY 0 WHILE DRIVING THIS IS A INSTRUMENT CLUSTER ISSUE AND WILL BE AROUND $500.00 TO FIX BUT I DO NOT HAVE THE MONEY FOR THIS BEFORE THIS STARTED THE GAS GAGE AND TEMP GAGE STARTED TO MESS UP AND BOUNCE AROUND. *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET IMPALA. THE CONTACT STATED THAT THE SPEEDOMETER WAS MALFUNCTIONING AND WOULD NOT REGISTER THE CORRECT SPEED. WHILE DRIVING APPROXIMATELY 30 MPH, THE SPEEDOMETER WOULD REGISTER 70-80 MPH. MOST RECENTLY, WHILE DRIVING AT 45 MPH, THE SPEEDOMETER REGISTERED MORE THAN 120 MPH, WHICH WAS OFF THE METER. THE DEALER ADVISED HER TO BRING IN THE VEHICLE SO THE INSTRUMENT CLUSTER COULD BE REPLACED. THE MANUFACTURER HAS NOT BEEN NOTIFIED. THE CURRENT MILEAGE WAS 75,545 AND FAILURE MILEAGE WAS APPROXIMATELY 74,600.

MY SPEEDOMETER IS READING 100 MPH WHEN I'M ONLY GOING 40 - 50. WHEN I COME TO A COMPLETE STOP, THE SPEEDOMETER MAY MOVE TO 60. IT'S TAKEN UP TO 3 - 4 DAYS TO MOVE BACK DOWN TO THE 0. THEN THE SAME PROCESS WILL START ALL OVER AGAIN. THE CAR ALSO TENDS TO DRIVE SLUGGISH WHEN THIS IS HAPPENING. COULD IT BE THE SPEEDOMETER OR TRANSMISSION??? I'VE BEEN TOLD TO REPLACE THE CLUSTER IN THE DASH BUT WILL THAT PREVENT THE SLUGGISHNESS ALSO? *TR

DIGITAL INSTRUMENT CLUSTER SPEEDOMETER AND FUEL LEVEL GAUGE, SPEEDOMETER GOES PAST 120MPH WHILE DRIVING AND CONTINUES CLIMBING UNTIL THE ENGINE IS SHUT OFF, FUEL GAUGE DOES THE SAME GOES PAST FULL WHEN LESS THAN FULL. THE PROBLEM IS NOT CONSTANT BUT OCCURS MOSTLY IN DAMP OR RAINY WEATHER. I HAVE FOUND THAT BOTH CAN BE RESET SIMPLY BY TURNING THE IGNITION KEY ON AND OFF UNTIL WHICH EVERY INSTRUMENT IS ACTING UP GOES BACK TO ZERO. IT 'S MORE OF A NUISANCE THAN ANY THING. *TR
