Cars acceleration causes me to be unable to pick up speed it decelerates up hills small or latg ramps cats constantly fly pass to avoid a multi car pile up it’s very dangerous!
Wiring harness has got hot and cause a short not getting fuel and more
TRANMISSON, EVAP, EVAPORRATIVE EMISSION CONTROL SYSTEM LEAKING
WHEN BACKING OUT OF THE DRIVE WAY AND GO TO ACCELERATE THE ABS/TRACTION CONTROL ENGAGES AND CAUSES THE CAR TO STOP. IT ALSO HAPPENS ON THE ROAD ONCE U COME TO A STOP AND OR STOP AND TURN ONTO A STREET OR HIGHWAY. ALMOST GOT REAR ENDED A FEW TIMES. I READ ONLINE AT ITS HAPPENING ALOT TO PEOPLE ALL OVER. THIS PROBLEM IS CONSTANT EVER SINCE I BOUGHT THE CAR. PREVIOUS OWER ADVISED ME OF THE PROBLEM AS WELL.
TURNED ON MY CAR STARTED PUSHING ON THE GAS MY CAR MADE A WEIRD VIBRATION TYPE SOUND. CAME UP ON MESSAGE BOARD TRACTION CONTROL AFTER A COUPLE TIMES OF IT DOING THAT, THE ABS AND TAX LIGHT COME ON AND ON THE MESSAGE WINDOW IT SAYS SYSTEM TRACTION SERVICE. IT KINDA FREAKED ME OUT CAUSE I WAS STOPPED AT A RED LIGHT WENT TO GO HIT THE GAS AND IT SAID TRACTION CONTROL AND I MOVED A LITTLE THAN I HAD TO LET GO OF GAS THEN TRY AGAIN. ALSO HAVE HAD A COUPLE INCIDENTS WHERE I GO TO BREAK AND IT MAKES A VIBRATION FEELING ON THE BRAKE AND BRINGS UP TRACTION CONTROL AGAIN. REALLY WOULD LIKE THIS CHECKED OUT VERY CONCERNED. DON'T WANT TO GET IN AN ACCIDENT CAUSE MY CAR FAILS TO TAKE OFF.
UNSURE IF MY 04 IMPALA IS AFFECTED IN THE TAKATA RECALL BECAUSE I HAVEN'T RECEIVED NOTICE.HAVE RECENTLY HAD EXTENSIVE REPAIRS COMPLETED BY A CERTIFIED MECHANIC. AND THE ABS, TRAC, CHECK AND BRAKE LIGHTS WON'T GO OFF. THE SECURITY LIGHT CONTINUES TO COME ON AND DISABLES THE CAR NOT ALLOWING IT TO START. CAUSING ME THE BE STRANDED UNANNOUNCED AND AT ANY RANDOM TIME. STEERING WHEEL TIGHTENS AND LOOSENS AT RANDOM TIMES. AFTER RESEARCHING PAST RECALLS BEFORE MY OWNERSHIP I AM UNSURE IF MY CAR HAS HAD THE RECALL ISSUES ADDRESSED. MY CAR HAS SOME TYPE OF MANUFACTURER COMPUTER GLITCH BUT GMC DOESN'T WANT TO OWN UP TO IT. AND I'VE KEPT ALL RECEIPTS ON REPAIRS I'VE COVERED. THESE ISSUES HAVE BEEN ON GOING SINCE THE ESTIMATED DATE ENTERED BELOW.
TAKATA RECALL KEY FALLS OUT WHILE I AM DRIVING SPEEDOMETER GAS GAUGE AND COMTROL PANEL NOT WORKING CAR JUMPS IN REVERSE
THE INSTRUMENT PANEL GAGES WILL NOT FUNCTION, ALL INDICATORS ARE FACING DOWNWARD AND DO NOT MOVE. THIS HAPPENS WHEN MOVING OR STANDING STILL.
FREQUENTLY, THE ABS ACTIVATES THE BRAKES WHILE IN MOTION AND NO PRESSURE IS PLACED ON THE BRAKE PEDAL. USUALLY THE ABS LIGHT AND TRACTION CONTROL TURN ON AFTERWARDS AND INDICATE THEY ARE NOW DISABLED. SOMETIMES THE LIGHTS TURN ON WHEN THE ENGINE IS STARTED. THE DEALER SAID THE SPEED SENSOR WAS DEFECTIVE, SO THEY WERE REPLACED TWICE, BUT THIS DID NOT FIX THE PROBLEM. THIS PORTABLE HAD BEEN ONGOING FOR OVER 6 MONTHS.
FAULTY/WORN IGNITION SWITCH IN THIS VEHICLE WILL GENERATE THE FOLLOWING ISSUES: (DETERMINED THROUGH TRIAL AND ERROR DUE TO CHRONIC ELECTRICAL ISSUES:) 1). ENGAGEMENT AND DISABLEMENT OF ABS SYSTEM BECAUSE OF LACK OF GOOD POWER TO THE SYSTEM FROM THE IGNITION SWITCH CIRCUIT. 2). ENTIRE LOSS OF DIRECTIONAL SYSTEM(TURN SIGNALS) AGAIN BECAUSE OF LACK OF GOOD POWER TO THE SYSTEM FROM THE IGNITION SWITCH CIRCUIT. THESE TWO SITUATIONS LEAD TO VEHICLE THAT IS UNSAFE TO DRIVE AT THE TIME OF THE FAILURE WHICH MAY HAPPEN STATIONARY OR WHILE IN MOTION. THESE ISSUES WERE INTERMITTENT AND WOULD HAPPEN AT ANY TIME. IGNITION SWITCH IN A VEHICLE SHOULD NOT GENERATE ISSUES SUCH AS THIS.
SECURITY LIGHT COMES ON RANDOMLY, HAVE TO WAIT TEN MINS TO START VEHICLE. SECURITY LIGHT COMES ON WHILE DRIVING, MY GAS FUEL GAUGE STOPPED WORKING SO I TRACK THE GAS MY MILES .. FIRST 20 MILES STRUGGLES TO GO, FIRST THOUGHT IT WAS FUEL PRESSURE REGULATOR TO THE FUEL PUMP TO TRANNY TO ALTERNATOR NOW IT WONT SHIFT INTO GEAR AND I DON'T KNOW WHAT TO DO ONE RECALL FOR THE IGNITION IS RIDICULOUS
I TURNED THE KEY TO START THE CAR AND WAS DRIVING AND MY GAS HAND,SPEEDOMETER AND OIL INDICATORS JUST FELL TO THE BOTTOM OF THE CIRCLE. INSTEAD OF SHOWING ME THE AMOUNT OF GAS I HAVE THE RED NEEDLE FALLS BEHIND THE "E". THE SAME IS TRUE FOR THE SPEEDOMETER,THE NEEDLE JUST FALLS TO THE BOTTOM,AND THE COLD/HOT INDICATOR IS AT THE BOTTOM OF THE PANEL. ISN'T THIS AN ELECTRICAL PROBLEM? *TR
TL* THE CONTACT OWNS A 2004 CHEVROLET IMPALA. WHILE DRIVING AT APPROXIMATELY 55 MPH, THE FUEL GAUGE FAILED TO PROVIDE THE ACCURATE READING LEVEL AND THE SPEEDOMETER DID NOT DISPLAY THE CORRECT SPEED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE FUEL GAUGE AND THE SPEEDOMETER NEEDED TO BE REPAIRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 60,000.
COME ON NOW, I SEE THE COMPLAINTS ON A BUNCH OF THINGS THAT IS WRONG WITH MY 2004 IMPALA. AN THERE IS MORE THAN ONE PERSON SAYING IT. THERE SEEMS LIKE THERE IS A SERIOUS PROBLEM HERE THAT YOU GUYS SEEM TO BE IGNORING AN REFUSING TO FIX. I THINK ITS ABOUT TIME FOR SOME PEOPLE TO GET TOGETHER AND FILE SOME KIND OF LAWSUIT AGAINST YOU GUYS IF YOU DON'T ADDRESS THESE ISSUES. NOW FOR THE SAME COMPLAINTS FOR MY IMPALA, NUMBER 1 IT DOES NOT LIKE TO START SOMETIMES AND THEN I HAVE TO WAIT 20 MINS TO AN HOUR JUST FOR IT TO FINALLY START. NUMBER 2 THE SECURITY LIGHT STAYS ON. NUMBER 3 THE GAGES TO MY SPEEDOMETER AND GAS MOVE ALL OVER THE PLACE AND DOESN'T GIVE ME THE ACCURATE READING. OTHER EXPERIENCES I'VE HAD NOTICED IS THAT MY BRIGHTS DON'T ALWAYS LIKE TO SHUT OFF THE FIRST TIME, THE CAR PULLS MAINLY TO THE RIGHT, BUT ALSO BACK AND FORTH. AND ALL THE BUTTONS AND LIGHT TO MY RADIO WORKS BUT NO SOUND COMES THREW. I HAVEN'T EXPERIENCED ANY OF THE OTHER THINGS IN THE COMPLAINTS YET BUT THESE ONES I HAVE AN THEY NEED TO BE ADDRESSED LIKE I SAID BEFORE SOMETHING IS DONE ABOUT IT BY THE PEOPLE. THANK YOU
TODAY MY CAR LOCKED UP AND MY STEERING LOCKED UP WHEELS AND SPEED JUST MY BRAKES WAS THE ONLY THING THAT WORKED . THE CAR JUST SHUT OFF, NOT START BACK UP. I WAS AFRAID BECAUSE I HAD MY CHILDREN IN THE CAR. *TR
HELLO, I JUST PURCHASED THIS VEHICLE FROM A USED CAR DEALER AND DROVE IT TO WORK TWO DAYS LATER. I WORK AN HOUR AWAY AND TAKE THE TURNPIKE....I NOTICED WHILE I WAS DRIVING THAT THE SPEEDOMETER WAS NEAR 90, AND WHEN I PULLED INTO MY JOBS PARKING LOT I WAS NEAR 40 MPH...THE PARKING LOT'S SPEED LIMIT IS 10 MILES PER HOUR WITH SPEEDBUMPS SO I KNEW SOMETHING WAS WRONG. WHEN I GOT OFF OF WORK MY GAS TANK READ PAST THE FULL MARK....I HAVE BEEN FILLING THE TANK EVERY OTHER DAY TO PREVENT BEING STRANDED. I IMMEDIATELY CALLED THE DEALER AND HE TOOK A LOOK AT IT. I PURCHASED THE CAR ON 01/17/15 AND TODAY'S DATE IS 02/01/15 AND I AM STILL WAITING TO GET THE PROBLEM RESOLVED. I'VE RESEARCHED ONLINE AND SEEN A LOT CHEVY IMPALAS HAVE THIS PROBLEM. MOST NOTABLY 2001-2005 I WOULD BE ETERNALLY GRATEFUL IF THE MATTER CAN BE RESOLVED. THANKS, [XXX] P.S. THERE WEREN'T SPECIFIC OPTIONS FOR THE PROBLEMS. THEY ARE:THE GAS GAUGE, SPEEDOMETER, THE WHOLE PANEL....I FOUND OUT THIS IS CALLED A CLUSTER? OR CLUSTER PANEL?
