2009 Chevrolet Impala

THIS IS THE 3RD TIME: WHILE DRIVING, SPEED REDUCES DRAMATICALLY, SERVICE ENGINE INDICATOR COMES ON FOLLOWED BY WARNINGS: "ENGINE POWER REDUCED" AND "SERVICE TRACTION CONTROL". MY RESEARCH ON THE ISSUE TO FIND OUT HOW TO FIX, SHOWS MANY PEOPLE HAVING THE EXACT SAME PROBLEM THAT ISN'T GETTING RESOLVED BY GM. ENGINE POWER REDUCTION TO SUCH A DRAMATIC SPEED CAN BE EXTREMELY DANGEROUS FOR NOT ONLY THE OPERATOR OF THE AFFECTED VEHICLE, BUT ALSO ANYONE ELSE ON THE ROAD NEAR THE DRIVER. *TR

DRIVING TO WORK AND THE SERVICE TRACTION CONTROL LIGHT WENT ON THEN ENGINE POWER REDUCED AND THROTTLE ERROR AND THE CAR WOULD NOT ACCELERATE AND POWERED DOWN. I WAS AT RED LIGHT SO I TURNED THE CAR OFF AND TURNED IT BACK ON THE CAR WOULD NOT ACCELERATE SO I TURNED IT OFF AGAIN AND WAITING PUT MY FLASHERS ON, WAITED A FEW MORE MINUTES AND THE CAR FINALLY STARTED TO MOVE. I TOOK TO THE DEALERSHIP BECAUSE IT'S A POWERTRAIN ISSUE AND I HAVE 100K POWERTRAIN WARRANTY AND THE DEALERSHIP SAID IT'S NOT POWERTRAIN AND WANTED $778 TO REPAIR, I CALLED CHEVY AFTER SEEING THE FORUMS ONLY THIS IS A KNOWN ISSUE THOUSANDS OF PEOPLE WITH THE SAME COMPLAINT AND CHEVY SAID THEY ARE GOING TO WORK WITH THE DEALERSHIP. I HAVE TO BE BACK AT WORK MONDAY AND DRIVE THROUGH A VERY ROUGH NEIGHBORHOOD I DO NOT WANT TO BREAKDOWN IN THAT NEIGHBORHOOD. *TR

THIS INCIDENT HAS HAPPENED SEVERAL TIMES LEADING UP TO THE CHECK ENGINE LIGHT REMAINING ON. AS I WOULD BE DRIVING DOWN THE ROAD AT APPROXIMATELY 45 MPH. THE VEHICLE WOULD SUDDENLY START TO JERK TO ACCELERATE AND DECELERATE WITHOUT ME WANTING TO CHANGE SPEEDS. SEVERAL OF THESE INCIDENTS HAVE BEEN WHILE I WAS DRIVING IN TRAFFIC. THEN THE MESSAGE "REDUCED ENGINE POWER" AND "SERVICE TRACTION CONTROL" WOULD APPEAR ON THE DASH AND THE TRACTION CONTROL LIGHT AND CHECK ENGINE LIGHT WOULD COME ON AND STAY ON. THIS WOULD ALSO CAUSE THE CAR TO REDUCE ITS SPEED AND CAUSE SIGNIFICANT ACCELERATION PROBLEMS. I REPLACED THE ACCELERATOR POSITION SENSOR AS INDICATED BY A CODE LOOK UP AND HAVEN'T HAD ANYMORE PROBLEMS WITH THE CAR AS OF OCTOBER 25, 2014. *TR

THE VEHICLE STARTED TO BEEP AND GAUGES DIDN'T WORK THEN WORK. THE GAUGES WENT BACK AND FORTH. THE LOCKS LOCKED AND UNLOCKED. I STARTED TO DRIVE AND DIDN'T KNOW HOW FAST I WAS GOING BECAUSE THE SPEEDOMETER DIDN'T WORK. THE ENGINE SEEMED TO WORK HARDER TO REACH HIGHWAY SPEED. WHEN I TURNED THE CAR OFF, THE STABILITRAK LIGHT CAME OFF BUT CHECK ENGINE LIGHT CAME ON. I TOOK THE CAR TO THE DEALER AND THEY CLEARED THE CODES FOR THE CHECK ENGINE LIGHT BUT COULDN'T FIND WHAT CAUSED THE STABILITRAK LIGHT TO COME ON. THEY TOOK THE ELECTRICAL HARNESS OFF AND PUT ELECTRICAL GREASE ON TO KEEP MOISTURE OUT. THAT DIDN'T SOLVE THE PROBLEM. I STILL HAVE THE STABILITRAK LIGHT TO COME ON AND GAUGES NOT TO WORK. NOW, IT HAPPENS WHEN I AM DRIVING. I FEEL THAT SOMEDAY THIS WILL HAPPEN AND HAVE NO CONTROL OF MY VEHICLE BECAUSE ONE TIME I FELT THE POWER STEERING TO GO BUT COME BACK RIGHT AWAY. *TR

WAS DRIVING WHEN THE TRACTION CONTROL LIGHT CAME ON AND MESSAGE CAME ACROSS SAYING SERVICE TRACTION CONTROL: THEN CHECK ENGINE LIGHT STARTED FLASHING RAPIDLY AT THE SAME TIME. FOLLOW BY A VERY LOUD KNOCKING NOISE FROM THE ENGINE. THEN SPEED WOULD NOT ACCELERATE. TURNED ON FLASHERS AND COASTED INTO PARKING LOT. VEHICLE HAD TROUBLES RESTARTING AND WOULD NOT MOVE. STEERING WHEEL WAS HARD TO TURN. TRIES TO DIE WHILE IDLING AFTER YOU GET IT TO START. DID DIAGNOSTICS AND CODE P0300 RANDOM MISFIRE DETECTION POWER TRAIN UNABLE TO ESTABLISH A LINK TO THE VEHICLE. FUEL SYSTEM 2 IS OL, LIFT AT 0%, SPARK PLUG 13.5, FUEL LEVEL LOW 38.8, ECU 14.417, LOW ACCELERATION. CONTACTED LOCAL CHEVY DEALERSHIP AND WAS TOLD IT WILL COST $35 TO TOW IT TO THEIR SHOP AND ABOUT $85 JUST TO RUN A DIAGNOSTIC ON THEIR MACHINE. IF IT IS A LIFTER THE COST WILL BE OVER $700 TO GET FIXED. I PURCHASED THIS AUTOMOBILE IN AUGUST 2013 AND HAVE JUST HAD IT A YEAR. SO NOW I HAVE A CAR PAYMENT ON A CAR THAT DOESN'T RUN. I BOUGHT IT AT WK MOTORS IN SEDALIA, MO. THIS IS THE SECOND TIME THIS CAR HAS HAD ISSUES AND WITHOUT A WARRANTY THE DEALERSHIP WONT DO ANYTHING!!! *TR

I CRANKED MY 2009 CHEVROLET IMPALA LEAVING A NEARBY GAS STATION AND THE MESSAGE SERVICE TRACTION CONTROL FLASHED, THEN ENGINE POWER REDUCED, AND THE CHECK ENGINE LIGHT CAME ON. MY CAR DROVE SLUGGISH HOME AT A VERY SLOW SPEED. LUCKILY I WAS ONLY ABOUT 5 MINUTES FROM HOME. THE NEXT MORNING NO MESSAGE WAS DISPLAYED AND THE CHECK ENGINE LIGHT WENT OFF. I TOOK IT TO ADVANCE AUTO PARTS AND THE CODE P2127 WAS DISPLAYED TWICE - THROTTLE PEDAL POSITION SENSOR. I SEE MOST OF THESE COMPLAINTS ARE SIMILAR TO MINE I JUST HAPPEN NOT TO BE ON THE HIGHWAY. IS GM INVESTIGATING THIS BECAUSE THIS IS SERIOUS WITH MULTIPLE OCCURRENCES? *TR

TRACTION CONTROL LIGHT COMES ON. POWER IS REDUCED. CAR RUNS AND DRIVES WELL. DRIVING ON INTERSTATE THE LIGHT COMES ON AND CUTS POWER. I HAD TO COAST TO A STOP ON THE SIDE OF THE HIGHWAY. WE WAITED 5 MINUTES AND THE CAR STARTED. THE LIGHT WENT OFF FOR A DAY AND THEN CAME BACK ON. I HEAR OF PEOPLE REPLACING PARTS AND THE PROBLEM NOT BEING FIXED. I CAN'T AFFORD TO DO THAT. *TR

THE FIRST TIME WAS ABOUT THREE MONTHS AGO IN MARCH 2014 BUT THE ENGINE NEVER DIED THEN. IT JUST HAD LESS POWER AND WAS BETTER THE NEXT TIME I STARTED THE CAR. DON'T KNOW WHAT THE MILEAGE WAS THEN, MAYBE ABOUT 52K. IT HAPPENED A COUPLE TIMES THAT SAME WEEK AND I WAS GOING ABOUT 40MPH. I ASKED ABOUT IT IN APRIL WHEN THE CAR WAS INSPECTED AND WAS TOLD THEY DIDN'T SEE ANY PROBLEMS BUT THAT IT MIGHT BE A SENSOR GOING OUT. THEN, ON JULY 4TH IN THE MOUNTAINS IN MISSOURI WAS THE NEXT TIME, GOING ABOUT 70 MPH DOWNHILL AND THIS IS WHEN IT DIED WITH LIKE 3-5 SECOND WARNING. FIRST THE LIGHT COMES ON THAT SAYS SERVICE TRACTION CONTROL THEN IT SAYS ENGINE POWER REDUCED AND DIES. NOTHING WORKS EXCEPT THE BRAKES. THIS HAPPENED AGAIN ON 7/12, GOING ABOUT 70 MPH AGAIN, DIED AGAIN. WAS IN THE MIDDLE LANE ON FREEWAY AND NEARLY GOT HIT AS MY CAR BARELY MOVED AND HAD HARD TIME GETTING TO THE SIDE OF THE ROAD. THE CAR DID NOT DIE, BUT HAD VERY LITTLE POWER, STEERING WAS VERY HARD AND I FELT LIKE I WAS IN EXTREME DANGER BOTH OF THESE TIMES. THIS NEEDS TO BE RECALLED!!! SO MANY OTHER REPORTS OF SAME PROBLEM NOT JUST IN THE 2009 BUT LATER YEARS, WHERE THE MANUFACTURE SHOULD ALREADY KNOW THIS IS AN ISSUE, BUT KEEPS MAKING THE CAR THE SAME WAY. THIS IS A TOTAL OUTRAGE!!! I CANNOT GET ON THE FREEWAY FEELING ANY SECURITY AND DON'T HAVE MONEY TO KEEP MAKING COSTLY REPAIRS ON THIS VEHICLE. MANY OTHER PROBLEMS WITH THIS CAR, BUT NOT SAFETY ISSUES AT THIS POINT. *TR
