2004 Chevrolet Impala

SPEEDOMETER FREQUENTLY INDICATES THE WRONG SPEED. THE SPEEDOMETER NEEDLE GOT STUCK AT ZERO MPH WHEN OUTSIDE TEMPERATE WAS ABOUT 20 DEGREES FAHRENHEIT. EVER SINCE THAT TIME (FOR 3 MONTHS NOW) THE SPEEDOMETER NEEDLE WILL FREQUENTLY STICK OR JITTER AS VEHICLE SPEED CHANGES. WHEN SPEEDOMETER NEEDLE IS STUCK IT FAILS TO RESET ALL THE WAY TO ZERO WHEN CAR IS STARTED. IT ONLY MOVES COUNTER-CLOCKWISE A LITTLE BIT WHEN STARTING THE CAR; IT DOES NOT MOVE BACK TO ITS RESET POSITION. THE RESET PROBLEM COULD BE COMPOUNDED BY A PROGRAMMING PROBLEM WITH THE SIGNALS SENT TO THE STEPPER MOTOR. THE FUEL GAUGE NEEDLE CAN BE HEARD AND SEEN DURING STARTING OF THE CAR TO SWING THE FULL RANGE OF THE FUEL DIAL TO RESET ITSELF. THE SPEEDOMETER ONLY MOVES A LITTLE BIT COUNTER-CLOCKWISE DURING STARTUP; NOT NEARLY ENOUGH TO RESET TO ZERO WHEN IT GETS STUCK. *TR

PROBLEM IS SPEEDOMETER. DRIVING ON HIGHWAY AT 60 MPH, AS SUN WAS SETTING, SPEEDOMETER SLOWLY WENT 60 TO ZERO OR A LOW NUMBER (OVER 5-10 MINUTES) WITH NO ACTUAL CHANGE IN SPEED. THIS HAPPENED ON SEVERAL CONSECUTIVE DAYS. CURRENTLY, FOR MANY MONTHS, SPEEDOMETER IS NOT ACCURATE. E.G. GOING ABOUT 40 MPH, READS 20 MPH. E.G. GOING ABOUT 35 MPH, READS 120 MPH, REPEAT 120 MPH. E.G. CAR AT STANDSTILL, SPEEDOMETER READS 120 MPH. E.G. GOING 40 MPH, READS ZERO. OFTEN SHOWS CORRECT SPEED THEN SLOWLY GOES DOWN WITH NO CHANGE IN ACTUAL SPEED. VERY DANGEROUS ON HIGHWAY AT NIGHT NOT KNOWING HOW FAST YOU ARE GOING. SEARCHED INTERNET, MANY SIMILAR COMPLAINTS. PROBLEM - POSSIBLY STEPPER MOTORS. NEED RECALL. *TR

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 30 MPH, THE HEADLIGHTS SUDDENLY FAILED. THE CONTACT HAD TO UTILIZE THE HIGH BEAM HEADLIGHTS IN ORDER TO ILLUMINATE THE ROADWAY. THE VEHICLE WAS INSPECTED BY A DEALER AND THEY ADVISED HIM THAT THE BRIGHT AND DIM SWITCH WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 85,000. UPDATED 5/24/11 *CN THE CONSUMER STATED THE MANUAL SWITCH DID NOT WORK. THE CONSUMER STATED HE HAD TO USE THE HIGHBEAM LIGHTS. UPDATED 096/03/11

EVENT: USE THE BRAKES. FAILURE: FRONT END SHAKES. REPAIR: REPLACE ROTORS. EVENT: DRIVE AT ANY SPEED. FAILURE: SPEEDOMETER GONE HAYWIRE, SAYS YOUR GOING 20 WHEN YOU ARE GOING 70? REPAIR: REBUILT INSTRUMENT CLUSTER. EVENT: ANY TIME ENGINE RUNNING. FAILURE: TEMP GAUGE HAYWIRE. YOU PULL OVER THINKING YOUR CAR IS OVERHEATING; IT'S NOT. REPAIR: REBUILT INSTRUMENT CLUSTER. EVENT: ANY TIME ENGINE RUNNING. FAILURE: FUEL GAUGE HAYWIRE. DON'T KNOW HOW MUCH FUEL YOU HAVE, COULD RUN OUT OF GAS (DID NOT HAPPEN TO ME). REPAIR: REBUILT INSTRUMENT CLUSTER. EVENT: USING BLINKERS. FAILURE: BLINKERS EITHER DON'T WORK WHEN ACTIVATED, OR FLASH RANDOMLY. REPAIR: REPLACE BLINKER/HAZARD MODULE. EVENT: TURNING IGNITION KEY FAILURE: NO CRANK, NO START - SECURITY LIGHT ON. WAIT A WHILE, CAR STARTS LIKE NOTHING HAPPENED. REPAIR: BYPASSED AND DISABLED SECURITY 'PASSLOCK' SWITCH. EVENT: USING WIPERS/RAIN.

EVENT: STOP AT INTERSECTION WITH ENGINE RUNNING FAILURE: ENGINE SURGING AND STALLING. YOU MUST KEEP YOUR FOOT PLANTED ON THE BRAKE SO THAT YOU DON'T RUN INTO THE CAR IN FRONT OF YOU. IT STALLED OUT OF STATE IN AN INTERSECTION. REPAIR: REPLACE MASS AIR FLOW SENSOR (MAF). THIS MOST RECENT MAF PROBLEM WAS THE LAST STRAW. THIS CAR HAS OTHER NON-SAFETY RELATED ELECTRICAL PROBLEMS, AS WELL AS THE NORMAL WEAR ITEMS THAT YOU WOULD REPLACE ON A 'REAL CAR'. THIS CAR IS A ROLLING ELECTRICAL DISASTER. THIS CAR IS A MONEY PIT, JUST LIKE ITS MANUFACTURER. GOOD LUCK WITH THAT CHEVY VOLT. *TR

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE CONTACT STATED THAT WHEN APPLYING THE BRAKES, THERE WAS AN ABNORMAL NOISE COMING FROM UNDER THE HOOD OF THE VEHICLE. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR SHOP WHO DIAGNOSED THAT THE ABS SYSTEM WAS DEFECTIVE AND WOULD NEED TO BE REPLACED. THE MANUFACTURER WAS NOT CONTACTED AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 120,000.

WHILE DRIVING ON A HIGHWAY AT 65 MPH, I NOTICED THE SPEEDOMETER NEEDLE DROPPING SLOWLY WHICH IT CONTINUED TO DO UNTIL IT RESTED AT ZERO. I CONTINUED DRIVING AT THE SPEED OF TRAFFIC (65 MPH) AND ALL THE WHILE THE SPEEDOMETER CONTINUED TO REGISTER "0." I PANICKED AND IF I HAD NOT BEEN USING A GPS NAVIGATOR THAT TOLD ME WHAT RATE OF SPEED I WAS TRAVELLING AT, GOD KNOWS WHAT WOULD HAVE HAPPENED. I HAVE BEEN ON SEVERAL BLOGS AND SEE THAT THIS PROBLEM IS VERY COMMON IN THE 2004 CHEVROLET IMPALA. CHEVROLET SHOULD INSTITUTE A RECALL AS THIS IS EXTREMELY DANGEROUS, AND IS ALSO COSTLY TO REPAIR. IT SEEMS TO AFFLICT ALL THE MODELS AT AROUND 40,000 MILES. AFTER I STOPPED TO GET GASOLINE, AND FILLED UP THE TANK, THE PROBLEM SEEMED TO CORRECT ITSELF, BUT ACCORDING TO THE BLOGS WITH OTHER OWNER COMMENTS, I HAVE NO CONFIDENCE THAT THIS WON'T HAPPEN AGAIN WITHOUT NOTICE. PLEASE SEE THAT CHEVROLET RECALLS THIS MODEL AND MAKES THE REPAIR AT NO CHARGE. THANK YOU.

HEADLIGHTS WENT OUT COMPLETELY AFTER DARK AT 55 MPH .THE PROBLEM IS IN THE QUALITY OF THE HIGH /LOW BEAM SELECTOR I WAS TOLD .I AM REPLACING THE THIRD SWITCH THIS WEEK 3/16/11 SINCE 09/20/09 . THIS TO ME SEEMS TO BE A GM SAFETY PROBLEM WHICH I THINK SHOULD BE A MFG RECALL . HAVE OWNED MANY OF VEHICLES AND NEVER TOTALLY LOST HEADLIGHTS . THE COST IS ALSO UNHEARD OF CAN BE $500 OR MORE

I OWN A 2004 CHEVROLET IMPALA SEDAN WHICH HAS 123,551 MILES ON IT. I BOUGHT IT WITH 108,000. I DISCOVERED AFTER I BOUGHT IT THAT MY SPEEDOMETER CLUSTER WAS ACTING UP. I COULD RESET IT BY TURN THE KEY ON AND OFF TIL IT REACHED 0 AND BOTH THE WATER TEMP GAUGE AND SPEEDOMETER WOULD WORK FOR A DAY OR SO. NOW, ONLY THE SPEEDOMETER WORKS BY RESETTING AND THE WATER GAUGE NEVER WORKS. I HAVE SEEN MAY OTHER IMPALA COMPLAINTS FOR THE SAME REASON. THEY DID A RECALL ON THE TRUCKS BUT NOT ON IMPALAS. I FEEL THIS SHOULD BE A RECALL. 2ND PROBLEM. TRANSMISSION SHOP DIAGNOSED AND REPLACE VALVE BODY. STILL DID SAME JUMPING IN AND OUT OF GEAR SO REPLACE AGAIN. STILL DOES IT. WAS TOLD BY ANOTHER TRANSMISSION SHOP WHO DROVE MY CAR THAT IT MAY BE CONTROL MODULE. IT NEVER DOES IT WHEN I TAKE TO A TRANSMISSION SHOP BUT MY MECHANIC GOT IT TO DO IT ON FRI. AND SAID HE THOUGHT IT COULD EITHER BE SPEEDOMETER CLUSTER RELATED OR MAY A CONTROL MODULE. IT IS AN INTERMINENT PROBLEM AND HAVE HAD SINCE I BOUGHT CAR IN DEC. 09. ANOTHER FRIEND SAID HE BOUGHT A NEW 08 AND IT DID SAME THING. NO ONE EVER FOUND OUT WHY. *TR

TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. THE HEADLIGHTS WERE ILLUMINATED AND AS THE LOW BEAMS WERE SWITCHED TO HIGH BEAMS, THE INTERIOR AND EXTERIOR LIGHTS FAILED. AS THE LOW BEAMS WERE ENGAGED, THE INTERIOR AND EXTERIOR LIGHTS CAME BACK ON THE FAILURE RECURRED WHENEVER THE EXTERIOR LIGHTING WAS SWITCHED FROM LOW BEAMS TO HIGH BEAMS. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 82,000. UPDATED 05/04/11 *BF UPDATED 05/11/11

SPEEDOMETER STOPS TRACKING SPEED. IT WILL STOP AT A RANDOM SPEED AND NOT RETURN TO ZERO UPON STOPPING THE CAR. WHEN I START DRIVING AGAIN IT WILL START TRACKING THE SPEED FROM THE INCORRECT POINT THAT IT STOPPED AT PREVIOUSLY AND THEN REPEAT THE FAULT STOPPING AT A TOTALLY DIFFERENT MPH POINT. ALSO IT WILL JUST FREEZE AT RANDOM SPEEDS. AT TIMES IT WILL GO ALL THE WAY TO THE HIGHEST POINT ON THE SPEEDOMETER AND FREEZE. I WOULD THINK THIS IS A VERY HIGH PRIORITY ON THE LIST OF SAFETY ITEMS. THERE SHOULD BE A RECALL.
