WIFE WAS DRIVING HOME AND THE ENGINE POWER WAS REDUCED AND SERVICE TRACTION CONTROL CAME UP ON THE DASH DISPLAY. POWER WAS CUT, LEFT HER DRIVING AT AROUND 40MPH I DROVE IT TODAY, JULY 1,2014, IT DID FINE FOR ABOUT THE FIRST MILE THEN SERVICE TRACTION CONTROL, REDUCED ENGINE POWER DISPLAY CAME ON AGAIN. I DROVE IT 4 TIMES TODAY, SEEMS THAT IF THE CAR SIT FOR A FEW HOURS, IT RAN FINE, FULL POWER, NO ISSUES FOR ABOUT THE FIRST MILE TO MILE AND A HALF THEN IT WOULD COME UP WITH THE SERVICE TCS AND REDUCED ENGINE POWER WHICH LEAVES YOU AT VERY REDUCED SPEEDS. LUCKILY I LIVE IN THE COUNTRY SO TRAFFIC WASN'T A HUGE ISSUE. I RESEARCHED ONLINE AND THIS SEEMS TO BE A COMMON OCCURANCE WITH MANY YR MODEL IMPALAS SO I WANTED TO REPORT MINE SO IT WOULD BE ON RECORD AS WELL. 2007...

WAS ABLE TO GET TO THE SIDE OF THE ROAD. HAD TO PUSH THE CAR INTO A PARKING LOT AS THE ENGINE WILL NO LONGER START BUT CRANKS OVER FINE. HAD TO BUY A SCANNER TO READ THE CODE BECAUSE THE CAR WAS NOT ABLE TO DRIVE TO A AUTO REPAIR SHOP OR AUTO PARTS STORE TO READ THE CODES. THE PO641 CODE WAS SET. CHECKED AND TESTED THE SENSOR WIRES FOR THE 5VOLTS EVERY ONE THAT I TESTED SHOWED OK. REPLACED THE GAS PEDAL ASSEMBLE BECAUSE OF THE CODE THAT COULD BE A SOURCE OF THE PROBLEM NO DIFFERENCE. CLEANED THE THROTTLE BODY UNIT NO CHANGE CAR WILL NOT START.CHECKED AND GAVE ALL THE WIRES A GOOD PULL AND...

ONCE AGAIN THE SERVICE TRACTION CONTROL AND ENGINE POWER REDUCED LIGHTS ARE ON. WE HAVE TAKEN THE CAR TO DON BROWN CHEVY DEALERSHIP MULTIPLE TIMES WITH NO FIX IN SIGHT. BEEN TOLD IT'S A CLIP THAT CAME LOOSE AND WAS FIXED MULTIPLE TIMES. IT WOULD BE HELPFUL TO FIND SOME PLACE THAT CAN ACTUALLY FIX THE PROBLEM OR FOR GM TO COME UP WITH A FIX. THIS IS NOT A RECALL ITEM AND SHOULD BE ON THE LIST DUE TO THE MULTIPLE INCIDENTS. THIS PROBLEM HAS BEEN OCCURRING INTERMITTENTLY ON THE CAR SINCE 2009. *TR

WHILE DRIVING MY 07' CHEVY IMPALA THE TEMPERATURE GAUGE ARM OFTEN WILL DROP TO 'C' AS IF THE ENGINE TEMPERATURE IS COLD, THEN THE DRIVERS INFORMATION DISPLAY PANEL WILL DISPLAY A MESSAGE "ENGINE HOT TURN OFF A/C". I'VE HAD THE THERMOSTAT REPLACED, RADIATOR COOLANT DRAINED AND REPLACED, HOPING TO FIX THIS PROBLEM, BUT I'M STILL DEALING WITH IT. AFTER DOING SOME RESEARCH I'M FINDING THAT THERE HAS BEEN OTHER CHEVY VEHICLE OWNERS DEALING WITH THIS SAME ISSUE, WHICH IS MOST LIKELY A BAD 'ENGINE COOLANT TEMPERATURE SENSOR (ECT). *TR

THE CHECK ENGINE LIGHT REMAINS ON IN THE VEHICLE. I HAD THE VEHICLE DIAGNOSED AND WAS TOLD THE THROTTLE SENSOR NEED TO BE REPLACED. THIS IS A DANGEROUS ISSUE THAT GM NEED TO ADDRESS.

MY WIFE'S DAILY DRIVER IS A 2007 IMPALA . SHE WAS DRIVING HOME WITH OUR THREE KIDS WHEN THE CAR STARTED SHAKING AND THE REDUCED ENGINE POWER DISPLAY CAME ON. AFTER THAT SHE COULD ONLY GO ABOUT 25MPH. THIS SCARED HER AND COULD HAVE CAUSED AN ACCIDENT. I LOOKED ONLINE AND FOUND FORUMS ABOUT A LOT OF PEOPLE HAVING THE SAME PROBLEM AND IT PISSES ME OFF THAT GM HASN'T RECALLED THESE VEHICLES . DOES SOMEONE HAVE TO DIE BEFORE THIS SITUATION IS TAKEN CARE OF? *TR

FIRST, WHEN I SLOW DOWN TO TURN A CORNER, I TAKE MY FOOT OFF THE GAS. AFTER THE TURN, WHEN I PRESS THE GAS I HAVE NO POWER. IT DOESN'T DIE, IT JUST WON'T GO ANYWHERE FOR ABOUT 15-20 SECONDS, NO POWER. THAT DOESN'T SOUND LIKE A LONG TIME UNLESS YOU ARE SITTING IN THE MIDDLE OF A BUSY INTERSECTION. I HAVE TO COME TO A COMPLETE STOP FOR ABOUT 20-30 SECONDS, THEN TAKE OFF. SOMETIMES IT GOES, BUT FEELS LIKE IT JERKS INTO GEAR. THAT'S OK AT STOP SIGNS BUT STOP LIGHTS THAT TURN GREEN AS I APPROACH CAN BE DANGEROUS. ALSO, IF I TURN A CORNER ONTO ANOTHER STREET, IT HESITATES. AND SOMETIMES I HAVE ALMOST BEEN HIT FROM BEHIND. PEOPLE EXPECT YOU TO TURN AND PROCEED. WHEN YOU JUST STOP, THEY MAY NOT. I ALSO NOTICED ONE DAY, WHEN I JUST COAST ON A LEVEL ROAD, MY...

ON 2/14/2013, I HAD THE THROTTLE POSITIONING SENSOR REPLACED AND AT THE SAME TIME HAD THE REAR DEFROST WIRING REPAIRED BECAUSE THAT HAD NOT BEEN WORKING FOR OVER A YEAR. ON 3/4/2013 THE CAR WOULD NOT START BY THE FACTORY REMOTE START, SO WENT OUT AND STARTED THE CAR WITH THE KEY, WHEN I RETURNED TO THE CAR THE VEHICLE WOULD NOT START AT ALL THE CHIME WOULD SOUND THE LIGHTS ON THE DASH FLASHED BUT NO START. I WAITED A FEW MINUTES THEN TRIED AGAIN, THE CAR STARTED BRIEFLY (50 SECONDS) "REDUCED...

AS I WAS DRIVING THE ENGINE LIGHT CAME ON AND THE DISPLAY READ REDUCED ENGINE POWER. THE CAR SLOWED DOWN AND RESISTED AS I ACCELERATED. I CAN ONLY DRIVE ABOUT 20 MILES PER HOUR. THERE IS NO WARNING AND THERE IS A DECREASE IN ACCELERATION. THERE WAS NO WARNING AND I HAVE MY CHILD IN THE CAR. THIS IS VERY DANGEROUS. *TR

MY AIR BAG LIGHT CONTINUES TO COME ON FOR NO REASON, MY TIRE SENSOR LIGHT COMES ON AS WELL EVEN WHEN THERE'S NOTHING WRONG WITH MY TIRES, MY SERVICE ENGINE LIGHT IS ON I GOT IT SERVICED AND ITS STILL ON , MY SEAT BELTS DO NOT WORK PROPERLY , MY HEAT AND AIR DOESN'T WORK PROPERLY AS WELL THERE'S SO MUCH WRONG WITH MY CAR AND I HAVE SPENT SO MUCH MONEY FIXING IT AND THE SAME PROBLEMS STILL OCCUR. *TR

RETURNING HOME FROM WORK ON INTERSTATE NOTICED IT TOOK HIGHER RPMS TO GET UP TO THE 65MPH SPEED LIMIT. AFTER DRIVING FOR A FEW MINUTES I STOPPED AT A RED LIGHT. THE VEHICLE COULD THEN ONLY GET UP TO 40MPH AND LOST POWER DOWN TO 10MPH WHEN I PULLED OVER AND CALLED IT A DAY. CURRENTLY AT THE SHOP WITH 10 DIFFERENT CODES SHOWING. UNFORTUNATELY I HAVE HAD IT JSUT OVER 5 YEARS AND NOT IN WARRANTY ANY MORE. *TR

SINCE I HAVE HAD MY IMPALA I HAVE HAD SEVERAL PROBLEMS WITH THE CA. THE FIRST PROBLEM THAT I NOTICED WAS THAT MY WINDSHIELD WIPER FLUID STOP COMING OUT AFTER ON HAVING THE CAR A FEW MONTHS, I LATER FOUND OUT THAT THE MOTOR HAD GONE OUT. ANOTHER PROBLEM THAT IM HAVING IS THAT THE CHECK TIRE SERVICE LIGHT CONTINUES TO COME ON EVEN AFTER, TIRES HAVE BEEN FILLED AND REPLACED, I HAVE ALSO NOTICED THAT ON OCCASIONS MANY OF THE OTHER SERVICE LIGHTS COME ON LIKE CHECK AIRBAGS, AND BRAKES EVEN AFTER CAR HAS BEEN SERVICED. MY BIGGEST ISSUE IS THAT MY TRANSMISSION FLUID HAS BEGUN TO LEAK OUT MY CAR AND NO ONE NOT EVEN THE DEALERSHIP CAN FIGURE OUT WHERE OR WHY ITS LEAKING. THIS CAUSES THE CAR TO HESITATE AND JERK UPON ACCELERATION. READING A LOT OF THE FORUMS OUT I'M NOT THE ONLY PERSON HAVING...
