While driving the car it would pop up a message saying “ENGINE POWER REDUCED”. Today while driving it home it popped up with a message saying “STARTING DISABLED, SERVICE THROTTLE” and then the car wouldn’t drive and I had to pull over on the side of the road. For months now when I drive and accelerate at times the car would almost grind. I believe it has to do with the traction control or the transmission.

My car has started slowing down abruptly and displaying Engine Power has been Reduced at random times, but has become more frequent. I have had an independent service center tell me it was the throttle body, so they replaced it. That didn't fix it, so they replaced the accelerator pedal/sensor. It still is happening and when on the interstate, it is so dangerous to slow down with no warning because you can get rear ended quite easily. This first started August 2021 when my wife and I started on a vacation and had to turn around and go home and is still happening, only more frequent. This past Saturday 7/16, I was traveling on Interstate 77 and the engine power kept cutting down about every 10 minutes, so I had to pull over and cut the engine off for a while until it reset. I can't trust it to go anywhere.

TO WHOM IT MAY CONCERN: I HAVE A 2009 CHEVY IMPALA WITH 100,000 MILES ON IT. THE 1ST TIME THIS ISSUE HAPPENED, I WAS DRIVING SLOWLY, ON A SIDE STREET, IN JULY 2019. OUT OF THE BLUE, THE FOLLOWING WARNINGS APPEARED: ENGINE POWER IS REDUCED, SERVICE STABILITRAK, SERVICE TRACTION CONTROL. IMMEDIATELY MY CAR STARTED RUNNING HORRIBLY (IT DIDN'T WANT TO GO, WAS CHUGGING, AND ALMOST FELT LIKE THE TRANSMISSION WAS SLIPPING). I PARKED IT. LATER I STARTED IT AND ALL WARNINGS WERE GONE, BUT THE ENGINE LIGHT WAS ON. . THE NEXT DAY I STARTED IT AND JUST THE ENGINE LIGHT WAS ON. 3RD DAY I STARTED IT, ENGINE LIGHT STILL ON. DROVE IT TO A SHOP,.RIGHT BEFORE I PULLED IN, THE LIGHT TURNED OFF! THEY SCANNED IT ANYWAY & SAID THAT NOTHING CAME UP. THE CAR HAS DRIVEN JUST FINE, NO WARNINGS OR LIGHTS UNTIL 11/25/2020. I WAS DRIVING ABOUT 20MPH, TURNED RIGHT ON A SIDE STREET AND ALL OF A SUDDEN ALL OF THE EXACT MESSAGES AS BEFORE CAME ON. VEHICLE IMMEDIATELY STARTED RUNNING SLOW AND "CHUGGING"AGAIN. I PARKED IT. WHEN I STARTED IT AGAIN LATER, ALL THE SAME MESSAGES WERE STILL THERE. IT'S DEFINITELY SCARY WHEN THIS HAPPENS & SINCE THE 1ST TIME IT HAPPENED, I WAS NERVOUS TO DRIVE IT FAR BECAUSE I WASN'T SURE WHEN IT MAY HAPPEN AGAIN. I WENT ON A CHEVROLET FORUM & READ THERE WAS A RECALL FOR THIS ISSUE. I WAS VERY PLEASED ABOUT THAT. I PUT IN MY VIN & IT STATED THAT THERE ARE NO RECALLS. SO I CALLED GM THIS MORNING. THE REP SAID THEY'RE AWARE OF THIS ISSUE, BUT THERE IS NOT A RECALL FOR IT. SHE THEN SAID THAT IT WOULD'VE COVERED BY SPECIAL WARRANTY BUT UNFORTUNATELY THAT WAS UNAVAILABLE AS OF APRIL 2019! HER ADVICE WAS TO TAKE IT TO A CERTIFIED DEALERSHIP AND HAVE IT CHECKED AND FIXED SOON FOR MY SAFETY! I ASKED WHY THERE ISN'T A RECALL, IF IT'S A KNOWN ISSUE AND SHE SAID I COULD TALK TO A CUSTOMER EXPERIENCE MANAGER AT THE DEALERSHIP AND MAYBE THEY COULD DO SOMETHING FOR ME. PLEASE HELP!

THIS IS NOT THE FIRST TIME THIS HAS HAPPENED. ON THE HWY GOING 60MPH, ALL OF A SUDDEN MY ENGINE POWER IS REDUCED AND AIRBAG LIGHT CAME ON. THE NEXT DAY THE AIR BAG LIGHT AND ENGINE LIGHT ARE BOTH ON. WENT TO MY MECHANIC FOR AN INSPECTION (WHICH I FAILED DUE TO THE AIRBAG) AND HE INFORMED ME TO CONTACT THE DEALERSHIP FOR RECALL. I DID, ONLY TO FIND OUT THE RECALL IS CLOSED AND I CAN'T GET THIS FIXED UNLESS I COME UP WITH A LOT OF MONEY. I EXPLAINED I NEVER GOT ANYTHING FROM THE MANUFACTURER ABOUT THE RECALL. HOW CAN I GET MY CAR FIXED ON A CLOSED RECALL?

WHILE DRIVING ON ROADS AND INTERSTATES, I FREQUENTLY RECEIVE A DASH NOTIFICATION "ENGINE POWER REDUCED" AND MY SERVICE TRACTION CONTROL AND CHECK ENGINE LIGHT COMES ON.

THE NOTIFICATION LIGHTS AND SYMPTOMS OCCASIONALLY GO AWAY AFTER TURNING THE ENGINE OFF AND ON, ONLY TO COME BACK LATER. I CANNOT FIND AND ANSWER TO THIS PROBLEM.

LATELY, I HAVE BEEN HAVING ISSUES WITH THE ACCELERATION OF MY VEHICLE. EVERY SO OFTEN, MY ENGINE LIGHT COMES ON AND I GET A "ENGINE REDUCED" NOTIFICATION, AND MY VEHICLE SLOWS DOWN. WHENEVER I REACH 40MPH, MY HP METER DROPS AND MY CAR STARTS SHAKING. THERE HAS EVEN BEEN A TIME WHEN MY CAR WOULD COMPLETELY SHUT OFF AND DISPLAY "IGNITION DISABLED". EACH TIME THIS HAS HAPPENED, THE VEHICLE WAS MOVING ON A HIGHWAY. I WENT TO A SHOP TO GET THE ERROR CODES AND I WILL UPLOAD THEM.

ISSUES WITH THE AIRBAG AND LIGHT THE BLINKERS SHORTED OUT, THE CAR KEPT DYING AND THE KEY GOT STUCK IN THE IGNITION IN A PARKING LOT. THE GEAR SHIFTER WAS GETTING STUCK IN DIFFERENT GEARS BEEN UNDRIVABLE SINCE THE BEGINNING OF AUGUST 2018 DIDN'T KNOW ABOUT THE RECALLS TILL AUGUST BUT THE RECALLS ARE IN 2016 AND 2014

I STARTED MY CAR AND THE CHECK ENGINE LIGHT AND SERVICE TRACTION CONTROL LIGHTS BOTH CAME ON. I GOT ON THE HIGHWAY AND TRIED TO ACCELERATE TO MERGE INTO THE LANE AND MY CAR WOULD NOT ACCELERATE AND THE STEERING WHEEL LOCKED. LUCKILY I WAS ABLE TO GET INTO THE EMERGENCY LANE BEFORE MY CAR SHUT OFF, BUT I WAS VERY CLOSE TO BEING BLASTED BY AN ONCOMING SEMI TRUCK. THIS COULD'VE BEEN FATAL TO ME IF I HAD NOT GOTTEN OVER IN TIME.

I WAS ON THE INTERSTATE, GOING THE SPEED LIMIT. I HAD THE CRUISE CONTROL ON WHEN THE CAR ALERTED ME THAT THE ENGINE POWER REDUCED AND SERVICE TRACTION CONTROL. I CONTINUED TO DRIVE AS THESE MESSAGES HAVE APPEARED ON MY CAR BEFORE. I TRAVELED ANOTHER 40 MILES ALONG THE INTERSTATE AND WAS ABOUT A MILE FROM MY EXIT. I WAS PASSING AN OVER-SIZED TRACTOR TRAILER GOING UP HILL WHEN THE CAR DISPLAYED STARTING DISABLED THROTTLE SERVICE AND THE CAR SHUT OFF. I WAS IN THE LEFT LANE AND HAD TO INITIATE MY EMERGENCY LIGHTS AND WAIT FOR THE TRACTOR TRAILER TO PASS ME SO I COULD MOVE THE CAR OVER TO THE RIGHT SHOULDER. AS THE CAR WAS COMPLETELY SHUTOFF AND WAS JUST COASTING, I HAD TO FIGHT THE STEERING WHEEL TO CONTROL THE CAR. I FEEL LIKE HAD MY SITUATION WAS JUST A LITTLE DIFFERENT, THE CAR COULD HAVE CAME TO A COMPLETE STOP IN THE MIDDLE OF THE INTERSTATE WITH CARS TRAVELING 70+ MPH AND POSSIBLY CAUSED A CRASH. I'VE ALREADY REPLACED THE THROTTLE POSITION SENSOR AND THAT REMEDIED THE SITUATION FOR A COUPLE MONTHS. THIS A HIGHLY DANGEROUS OCCURRENCE THAT I KNOW IS COMMON WITH THE IMPALA'S AS I'VE HEARD IT HAPPENING TO SEVERAL OTHER PEOPLE OWNING IMPALA'S.

I WAS DRIVING ON THE HIGHWAY WHEN THE SERVICE TRACTION CONTROL CAME UP ON THE DASH ALONG WITH THE TRACTION CONTROL LIGHT, WITH IN SECONDS OF THIS HAPPENING THE CAR READ REDUCED ENGINE POWER. THE CAR IMMEDIATELY LOST POWER AND SLOWED DOWN TO A MAXIMUM OF 25 MPH. THIS SUDDEN LOSS OF POWER CAUSED THE CARS BEHIND ME TO NEARLY MISS REAR-ENDING ME. I HAD TO DRIVE IN THIS CRIPPLED MODE 10 MILES TO REACH THE CLOSEST EXIT. IT IS DUE TO A FAULTY THROTTLE POSITION SENSOR. THIS SEEMS TO BE A VERY COMMON PROBLEM WITH THESE VEHICLES AND CAN CAUSE A SUDDEN LOSS OF POWER.

TOOK CAR TO OUR MECHANIC, THERE WAS A SERVICE BULLETIN, TO REPLACE THROTTLE BODY ASSEMBLY. SINCE THEN, 2 LETTERS FROM GM ABOUT COVERING COST OF THROTTLE SENSOR, BUT NOT ASSEMBLY. GM IS NOT TAKING CARE OF THE REAL PROBLEM, THE WHOLE ASSEMBLY NEEDS TO BE REPLACED, NOT JUST THE SENSOR! I'VE KEPT THE PART AND INVOICE AND LETTERS FROM GM, THEY SHOULD JUST RECALL BEFORE IT TURNS INTO A CLASS ACTION LAWSUIT!

MY CAR WAS TAKEN INTO THE DEALER TO CHECK ON THE "SERVICE ENGINE SOON" WARNING AND I WAS INFORMED THAT THE COMPUTER SHOWED IT AS AN APPS ISSUE. THEY CHECKED THE APPS AND I WAS INFORMED THAT THEY COULDN'T FIND ANYTHING WRONG AND THAT IT HAD BEEN RESET WITHIN THE COMPUTER SYSTEM AND I WAS GOOD TO GO. TWO MONTHS LATER WHILE TRAVELING AT A SPEED OF 55 MPH ON A HIGHWAY, THE SERVICE ENGINE LIGHT CAME ON, SERVICE STABILITRAK APPEARED ON THE INSTRUMENT PANEL, TRACTION CONTROL OFF LIGHT UP ON THE INSTRUMENT PANEL AND THEN THE RING TONE AND THE "ENGINE POWER IS REDUCED" CAME ON THE INSTRUMENT PANEL. THE NEXT THING I KNEW WAS THAT I HAD ABSOLUTELY NO ACCELERATION AT ALL! I WAS EXTREMELY FORTUNATE THAT THE VEHICLES BEHIND ME WERE FAR ENOUGH BEHIND ME AND I WAS ABLE TO GET OFF OF THE ROAD AND ON TO THE SHOULDER. HAD THAT NOT BEEN THE CASE THERE COULD HAVE BEEN A SERIOUS ACCIDENT CAUSING NUMEROUS INDIVIDUALS TO BE INJURED OR KILLED. I HAD THE VEHICLE TOWED AND CHECKED AND IT WAS DEFINITELY THE APPS (ACCELERATOR PEDAL PERFORMANCE SENSOR) THAT WAS DEFECTIVE. NOW NEARLY 2 YEARS LATER, IT HAS HAPPENED AGAIN. THE EXACT SAME WARNINGS CAME ON AGAIN, ONLY THIS TIME I WAS TRAVELING IN INCLEMENT WEATHER AND DURING RUSH HOUR TRAFFIC. THERE ARE NUMEROUS COMPLAINTS REGARDING THE EXACT SAME ISSUE AND CHEVROLET/GM NEEDS TO ISSUE A RECALL AS THE APPS IS DEFECTIVE. IF NO RECALL IS ISSUED IT IS A MATTER OF TIME BEFORE INNOCENT PEOPLE ARE KILLED.

MY NAME IS [XXX] AND I PURCHASED A 2009 CHEVY IMPALA, WITH 123,000 MILES ON IT, IN AUGUST 2015 FROM MAC CHURCHILL AUTO MALL IN BEDFORD, TEXAS. I HAVE HAD NO PROBLEMS WITH THIS CAR SINCE ITS PURCHASE UNTIL NOVEMBER 29TH. WHILE EN ROUTE TO EMORY, TEXAS, MY CAR STARTED DISPLAYING "ENGINE POWER IS REDUCED" AND "SERVICE TRACTION CONTROL" MESSAGES. ABOUT 99% OF THE WAY THERE, I SUDDENLY GOT A LURCH AND MY CAR SLOWED DOWN, WITH STEERING AND BRAKING NOT WORKING. I WAS ABLE TO GET MY CAR OFF THE HIGHWAY SAFELY BUT HAD TO USE MY EMERGENCY BRAKE TO STOP MY VEHICLE AND GET IT TURNED OFF. I TRIED REPEATEDLY FOR SEVERAL MINUTES TO GET IT GOING AGAIN, BUT IT WOULD NOT START. AFTER ABOUT FIVE MINUTES, THE CAR RESTARTED NORMALLY AND HAS PERFORMED FLAWLESSLY SINCE. HOWEVER, I AM CONCERNED. I'VE HAD A GARAGE PULL AND DIAGNOSE THE PROBLEM. THE ERROR CODES THAT WERE PULLED ARE P2122 AND P2138 ,REGARDING THE ACCELERATOR PEDAL POSITION SENSOR. I'VE RESEARCHED THIS AND THIS APPEARS TO BE A COMMON PROBLEM FROM WHAT I'VE BEEN ABLE TO ASCERTAIN FROM MY RESEARCH. BUT I'M CONFUSED AS TO WHETHER THIS IS A RECALL ITEM BASED UPON THIS: HTTP://WWW.NAIOA.COM/V2/MODULES.PHP?NAME=FORUMS&FILE=VIEWTOPIC&T=49934 . I'M NOW TRYING TO UNDERSTAND WHETHER I CAN GET THIS FIXED BECAUSE I'M NOT SURE THIS IS COVERED UNDER MY USED CAR WARRANTY AND I DO NOT FEEL COMPELLED TO PAY FOR A REPAIR THAT GM HAS BEEN AWARE OF BUT FAILED TO NOTIFY MY DEALERSHIP OR ME AS A OWNER, UNTIL I GOT A LETTER ON 12/9/15 INDICATING THAT THERE MAY BE A PROBLEM...WELL AFTER I STARTED HAVING PROBLEMS. I WANT GM TO FIX THIS AT THEIR EXPENSE. IT IS A SAFETY HAZARD HERE IN THE DFW AREA BECAUSE THIS COULD REOCCUR WHILE I'M IN HEAVY TRAFFIC AND HAVE NO WAY TO STOP BEFORE SOMEONE HITS ME OR I HIT SOMEONE.

FOR A FEW YEARS I'VE HAD PROBLEMS WITH THE ACCELERATOR PEDAL. THE FIRST TIME WAS ROUGHLY TWO YEARS AGO WHEN THE CAR COMPLETELY LOCKED UP AND SHUT DOWN ON THE HIGHWAY JUST BEFORE RUSH HOUR. I RECEIVED AN ERROR CODE TO CHECK TRACTION CONTROL AND THAT THE ENGINE POWER IS BEING REDUCED. THE CAR THEN LOOSES SPEED DROPPING DRASTICALLY. THE FIRST TIME I WAS IN THE FAST LANE ON THE HIGHWAY AND THE VEHICLES COMPUTER SYSTEM SHUT DOWN. THE STEERING WHEEL LOCKED MAKING IT VERY DIFFICULT TO VEER OFF TO THE SIDE OF THE HIGH WAY. LUCKILY NO OTHER VEHICLES WERE DIRECTLY BEHIND ME, AND I WAS ABLE TO GET THE CAR TO THE SIDE OF THE HIGHWAY ACCIDENT FREE. I'VE NEVER BEEN SO AFRAID AND TERRIFIED IN MY LIFE. I FEAR THIS ISSUE WILL CAUSE FATALITIES THAT CAN BE PREVENTED. I HAD THE CAR SERVICED AT A CHEVROLET DEALERSHIP IN ANN ARBOR MI WHICH WAS AN EXPENSIVE FIX! SINCE I'VE HAD THE ACCELERATOR PEDAL REPLACED, THE VEHICLE HAS SHUT OFF TWO OTHER TIMES FOLLOWED BY THE SAME WARNING MESSAGE TO SERVICE TRACTION CONTROL AND ENGINE POWER BEING REDUCED. I'VE WRITTEN IN TO GM AND THEY CONTINUE TO REQUEST THAT I PAY A DIAGNOSTIC FEE AT A DEALERSHIP FOR THEM TO ADDRESS THE CAUSE. I CANT CONTINUE TO PAY $200-$300 FOR THIS FIX WHEN IT IS A MANUFACTURERS ISSUE. THIS RECALL HAS BEEN DONE ON OTHER CHEVROLET MODELS AND I AM PRAYING FOR A RECALL ON THE 2009 IMPALA. THIS IS A MAJOR SAFETY ISSUE TO MY FAMILY AND THE DRIVERS WHO ARE AROUND ME. THE ISSUE IS STILL PRESENT AND IS A MAJOR CONCERN. THE VEHICLE SPEED CANT EXCEED 40MPH AT TIMES, OR WILL INSTANTLY DROP AT UNEXPECTED MOMENTS. PLEASE INVESTIGATE THIS ISSUE.

I HAD THE ENTIRE FAMILY IN THE CAR AND WAS THANKFUL THAT THIS DIDN'T CAUSE AN ACCIDENT. I AM LOOKING FOR ANSWERS AND PLAN ON TAKING IT TO THE CHEVY DEALERSHIP I PURCHASED THE CAR FROM TODAY OR TOMORROW.

MY WIFE AND I WERE DRIVING DOWN THE INTERSTATE AT APPROXIMATELY 65 MPH. A LIGHT ON THE DASH CAME ON SAYING ENGINE POWER REDUCED. AT THAT POINT MY VEHICLE SLOWED DOWN TO NEARLY 20 MPH WHILE I WAS STILL ON THE INTERSTATE IN MODERATE TRAFFIC. I PULLED OFF TO THE SIDE OF THE ROAD AND TURNED MY VEHICLE OFF TO TRY TO INVESTIGATE THE PROBLEM. AT THAT POINT MY VEHICLE WOULD NOT START FOR ABOUT 10 MINUTES. AFTER GETTING MY VEHICLE TO START I IMMEDIATELY DROVE IT HOME. THIS ISSUE COULD HAVE CAUSED A VERY SERIOUS ACCIDENT THAT WOULD HAVE INJURED MY WIFE AND I, BUT MORE IMPORTANTLY OUR 7 YEAR OLD DAUGHTER RIDING IN THE BACK SEAT ALONG WITH ANY ONE ELSE INVOLVED. I HAVE BEEN ON MANY DIFFERENT FORUMS TRYING TO FIGURE OUT THE CAUSE OF THE PROBLEM, AND IT SEEMS THERE ARE MANY PEOPLE WITH THIS EXACT PROBLEM ON THEIR CHEVROLET IMPALAS.

MY 2009 CHEVY IMPALA HAD EXPERIENCE INTERMITTENT MESSAGE "SERVICE TRACTION CONTROL" ALONG WITH "REDUCED ENGINE SPEED" SINCE AUGUST OF 2012. IT HAPPENED MAYBE 1-2 TIMES PER YEAR FOR THE LAST FEW YEARS. THE MESSAGE WOULD CLEAR ITSELF AFTER THE CAR WAS TURNED OFF AND SAT FOR A FEW MINUTES. ON JULY 24TH, MY CAR EXPERIENCE THESE SAME MESSAGES ONCE AGAIN. HOWEVER, THE MESSAGE CAME AND WENT MULTIPLE TIMES AND ALL SPEEDS IN TOWN AND ON THE HIGHWAY. THE MESSAGE FINALLY STAYED AND DID NOT GO AWAY ON JULY 25TH. I SCHEDULED SERVICE AT THE LOCAL DEALER ON THURSDAY, JULY 30. THEY CHANGED THE ACCELERATOR PEDAL AND THOUGHT IT WAS AN ISSUE THAT GM ISSUED A SPECIAL CONDITION ON IN APRIL 2015. ON THE WAY HOME FROM THE SHOP, THE MESSAGE APPEARED AGAIN. THUS, THE CAR WAS AGAIN SERVICED AT THE LOCAL DEALERSHIP ON FRIDAY, JULY 31. BY AUGUST 1, THE "SERVICE TRACTION CONTROL" LIGHT BLINKED ON AND THEN WENT OFF QUICKLY. IT DID THE SAME THING ONE TIME ON AUGUST 2ND. TODAY, AUGUST 3RD, THE LIGHT WENT OFF THREE TIMES IN A SHORT DRIVE AND IS ONCE AGAIN STUCK ON. I'M VERY WORRIED THAT THE REDUCED ENGINE SPEED WILL RETURN WHEN I AM ON A HIGHWAY. THIS IS A KNOWN ISSUE BY GM OR THEY WOULDN'T HAVE ISSUED A SPECIAL CONDITION. THEY ONLY WILL FIX THIS UP TO 120,000 MILES. IF MY ENGINE TURNS OFF WHILE MOVING AT 70MPH ON HIGHWAY, THIS WILL BE HUGE SAFETY CONCERN. I'M WAITING ON THE DEALER TO CALL ME BACK TO ONCE AGAIN RETURN MY CAR FOR REPAIR.

MECHANIC HAD TO REMOVE CODES TO PERMIT TO DUPLICATE PROBLEM, COULD NOT DUPLICATE AND TOLD ME TO WAIT UNTIL RECURRED. WHILE LOOKING FOR REPAIR SHOP WAS SCARED IT WOULD HAPPEN AGAIN RECEIVED LETTER FROM GM STATING IF THE ABOVE CONDITION HAD OCCURRED THEY WOULD FIX. CALLED GM DEALER MENTIONED LETTER THEY REFUSED TO REPAIR UNLESS THE MESSAGES WERE PRESENT ON PANEL, REFUSED TO LOOK AT THE VEHICLE. CALLED GM CUSTOMER SERVICE REFERENCING LETTER, EXPLAINED GM DEALER REFUSED TO REPAIR. WAS TOLD BY ANGELA ISSUE WAS SAFETY RELATED PROBLEM BUT GM WOULD NOT ADMIT TO SAFETY ISSUE. GM AGREED TO PAY FOR ONE HOUR OF DIAGNOSTIC TIME TO DETERMINE IF VEHICLE QUALIFIED FOR REPAIR, DEALER WAS UNABLE TO DUPLICATE PROBLEM, REFUSED TO REPAIR. CALLED GM AND WAS TOLD NO REPAIR WOULD BE MADE EVEN THOUGH THE PROBLEM HAD OCCURRED AS STATED IN THE LETTER AND TO WAIT UNTIL SITUATION OCCURRED AGAIN THEN NOT TO START ENGINE AND TOW TO GM DEALER. WAS TOLD GM WOULD NOT PAY FOR TOW OR INCONVENIENCE AND IF THEY COULD SEE CODES THEY MIGHT REPAIR PROBLEM. THIS IS DEFINITELY A SAFETY ISSUE SINCE WHEN THIS OCCURS THE VEHICLE LOSES ALL POWER AND BASICALLY SHUTS DOWN AND WILL NOT ACCELERATE BEYOND 5 MPH IF AT ALL.

Mileage: 100,000

I WAS DRIVING ON THE HIGHWAY AND ALL OF THE SUDDEN CHECK ENGINE LIGHT AND TRACTION CONTROL LIGHT COME ON. WARNINGS SERVICE TRACTION CONTROL AND REDUCED ENGINE POWER ARE DISPLAYED AND ALL BUT SHUTS MY CAR OFF IN THE MIDDLE OF THE HIGHWAY CAUSING CARS TO SLAM ON THEIR BRAKES AND SWERVE BARELY MISSING ME. I GET OVER TO THE SIDE OF THE ROAD AND TURN THE CAR OFF. THEN TURN THE CAR BACK ON SAME MESSAGES AND WON'T GO NO WHERE. DO THE SAME THING AGAIN ONLY WAITING LONGER AND NO MESSAGES BUT CHECK ENGINE LIGHT STILL ON. I DRIVE HOME. NEXT DAY NO WARNINGS OR LIGHTS. COUPLE WEEKS GO BY DOES THE WHOLE WARNINGS AND LIGHTS AND SLOWS CAR DOWN AGAIN BUT DOESN'T COMPLETELY SHUT IT DOWN. I WAS IN REGULAR STREET TRAFFIC THIS TIME ABOUT 35MPH. AND NOW IT'S MORE FREQUENT SOMETIMES A COUPLE TIMES A DAY TO ONCE EVERY DAY OR TWO. THIS NEEDS TO BE LOOKED AT. I'M READING ABOUT THIS PROBLEM ON A LOT OF IMPALAS CAUSING MAJOR PROBLEMS AND WRECKS. *TR

I HAD THE LEFT SPEED SENSOR REPLACED AND THE ACCELERATOR SENSOR REPLACE ON AUGUST 8TH AFTER THE DEALERSHIP HAD FIXED THIS PROBLEM IN APRIL AND AGAIN IN JUNE. I WAS TOLD THEY CHANGED SENSORS THEN ALSO, BUT I AM NOT SURE OF WHICH ONES AT THAT TIME. I AM NOW HAVING THE SAME PROBLEM FOR THE FORTH TIME. REPLACING THE SENSORS EVERY FEW MONTHS IS GETTING EXPENSIVE. ALSO NOT VERY SAFE. I CONTACTED GM AND THE WOMAN TOLD ME TO TAKE IT BACK TO THE DEALERSHIP TO BE FIXED AGAIN.

WHILE ON MY WAY HOME FROM WORK ON A MAJOR HIGHWAY, MESSAGE LIT UP SAYING ENGINE POWER IS REDUCED, SERVICE TRACTION CONTROL, THEN SAID STARTING DISABLED AND THE ENGINE SHUT OFF MID HIGHWAY WITH NO TIME TO REACT. I WAS ALMOST HIT BY SEVERAL CARS, TRACTOR TRAILER, AND BUSES. I HAD NO POWER STEERING, NOTHING. I HAVE 5 CHILDREN WHO ARE OFTEN IN THE CAR WITH ME AND THIS CREATED A MESS OF TRAFFIC AND COULD HAVE KILLED PEOPLE. AFTER BEING SCARED OUT OF MY MIND AND STUCK HALF IN A HIGHWAY LANE FOR 5 MIN WITH TRAFFIC SWERVING, THE CAR STARTED BACK UP WITH NO ISSUES AND I CONTINUED HOME. NO SIGN OF ANYTHING TODAY, HOWEVER I AM READING THOUSANDS OF COMPLAINTS ONLINE FROM OTHER CHEVY IMPALA OWNERS WHO STATE THEY ARE EXPERIENCING THE SAME ISSUES AND IT COMES AND GOES AND HAVE TRIED EVERYTHING TO FIX IT AND IT STILL HAPPENS EVERY SO OFTEN SOMETIMES MORE THAN OTHERS.

ONCE I STARTED THE VEHICLE BACK UP AND THE IGNITION SWITCH SEEMED TO BE STUCK AND THE AIR BAG LIGHT DISPLAYED ON THE DASHBOARD. WHEN I TURN OFF THE VEHICLE AND TRY TO REMOVE THE KEY THE KEY WILL NOT COME OUT SO I HAVE TO PUT IT INTO NEUTRAL AND BACK INTO PARK A FEW TIMES BEFORE IT WILL RELEASE THE KEY.

WHILE DRIVING ON THE HIGHWAY AT APPROXIMATELY 70 MPH THE CAR BEGAN TO LOSE ACCELERATION AND DROPPED ALL THE WAY DOWN TO 40 MPH. THE CHECK ENGINE LIGHT, SERVICE TRACTION CONTROL, SERVICE STABILITRAK, AND REDUCED ENGINE POWER MESSAGE DISPLAYED AS WELL. THE CAR BEGAN SHAKING AND WOULD NOT ACCELERATE. I HAD TO PULL OFF TO THE SIDE OF THE HIGHWAY AND TURN THE CAR OFF TO TRY AND GET THE ISSUE TO SUBSIDE. ONCE BACK ON THE ROAD, NOT MORE THAN 3 MILES LATER THE ISSUE SURFACED AGAIN. I ENDED UP HAVING TO GET OFF THE HIGHWAY AND DRIVE (VERY SLOWLY) BACK TO MY HOUSE. NOT SURE IF IT WILL BE SAFE TO DRIVE BACK TO THE DEALERSHIP TO BE ADDRESSED. I HAVE REPLACED THE WHEEL HUBS AND THROTTLE PEDAL SENSOR IN THE PAST FEW YEARS IN AN ATTEMPT TO CORRECT. THIS WAS AN INTERMITTENT ISSUE UNTIL RECENTLY AND EVEN AFTER HAVING IT FIXED BY A CERTIFIED CHEVROLET DEALERSHIP, THE ISSUE OCCURRED AGAIN. THIS MOST RECENT INCIDENT COULD HAVE ENDED IN SERIOUS INJURY HAD I NOT BEEN LUCKY ENOUGH TO NOT HAVE ANY CARS IMMEDIATELY AROUND ME.

ON MY DISPLAY I HAVE SEEN DAILY (SERVICE TRACTION ACTION) AND (ENGINE POWER REDUCED) ALONG WITH (SERVICE AIRBAG) FOR MORE THAN A YEAR, DID NOT SERVICE DUE TO COST AND IT IS NOT MY FAULT! MY CAR USUALLY SLOWS DOWN ONCE THE ENGINE POWER REDUCED DISPLAYS CAUSING THE CAR TO JERK DUE TO ME TRYING TO GIVE IT MORE GAS SO AS NOT TO BE HIT FROM THE BACK. AS MY GRANDCHILDREN AND I WERE HEADED HOME ON THE FREEWAY MY CAR DECIDED TO JUST SHUT OFF. ON THE DISPLAY IT READ FIRST.. SERVICE TRACTION ACTION AND THEN STARTING DISABLED SERVICE THROTTLE. MY CAR IMMEDIATELY LOST POWER AND I BEGAN TO PRAY HOPING I WOULD NOT GET HIT FROM THE BACK WITH MY GRANDCHILDREN SITTING IN THE BACK. ONCE I PULLED OVER MY CAR WOULD NOT START I SAT FOR ABOUT A MINUTE AND TRIED TO START AGAIN AND IT STARTED. JUST TODAY 01/12/2015, WITH MY GRANDCHILDREN IN THE BACK OF MY CAR AGAIN MY CAR DECIDED TO LOOSE POWER AGAIN BUT THIS TIME IT DID SOMETHING VERY DIFFERENT, IT WOULD NOT ALLOW ME TO FIRST REVERSE AND THEN IT ALLOWED ME TO BUT SOON AFTER I COULD NOT GO FORWARD. THE GAS PEDDLE ACTED AS THOUGH THE CAR WAS COMPLETELY TURNED OFF BUT THE CAR WAS RUNNING. WHEN I ATTEMPTED TO PRESS THE GAS PEDDLE I PRESSED IT ALL THE WAY DOWN TO THE FLOOR, NOTHING HAPPENED. I ENDED UP CALLING A TOWING SERVICE AND AFTER TELLING THEM WHAT HAPPENED I WAS TOLD MY ISSUES STEMMED FROM A ELECTRICAL SYSTEM ISSUE THAT CHEVY HAD RECALLED. THIS DOES NOT MAKE ANY SENSE FOR SO MANY OF US TO GO THROUGH THE SAME ISSUES BUT NOTHING BE DONE ABOUT THESE ISSUES. SOMETHING NEEDS TO BE DONE QUICKLY!! *TR

WHEN IM DRIVING ON THE FREEWAY OR DRIVING 35 MPH THE CAR GETS ON A LIMP MODE AND SHOWS A "POWER ENGINE REDUCE: AND TRACTION CONTROL AND SOMETIMES TURNS OFF ON ME WHILE DRIVING I ALREADY REPLACE THE (TPS) AND THE THROTTLE BODY BECAUSE THAT'S WHAT THE CAR COMPUTER WAS TELLING ME AND I ALREADY TOOK THE CAR TO A DIFFERENT MECHANICS AND THEY TELL ME NOTHING IS WRING WITH IT.

I WAS ON HIGHWAY ONE EVENING AND MY CRUISE CONTROL WAS ENGAGED. MY POWER WENT OUT COMPLETELY ON THE CAR. I IMMEDIATELY NOTICED THAT THE CAR SHUT DOWN AND I WAS ABLE TO COAST TO THE SIDE OF THE HIGHWAY. AFTER GATHERING MY BEARINGS, I WAS ABLE TO TURN THE CAR BACK ON AND DRIVE OFF THE FREEWAY. IT WAS DETERMINED THAT MY OIL WAS LOW (NO WARNING LIGHT). PRIOR TO THIS INCIDENT, I WAS GOING DOWN HILL ON A LOCAL STREET WHEN MY WARNING SYSTEM CAME ON AND INDICATED THAT I HAD REDUCED ENGINE POWER AND TRACTION STABILITY CONTROL ISSUES. AFTER GOING TO THE DEALER, IT WAS DETERMINED THAT MY OIL WAS EXTREMELY LOW, HOWEVER NO LEAKS OR CAUSE WAS EVER FOUND. PRIOR TO THIS, I HAD TO GET MY ACCELERATOR SENSOR REPLACED BECAUSE THE REDUCED ENGINE POWER WARNING CAME ON. IT WAS NOT COVERED UNDER WARRANTY AND I HAD TO PAY SEVERAL HUNDRED DOLLARS TO 'FIX' THE ISSUE. AS RECENTLY AS YESTERDAY, JUNE 16, 2014, I TURNED MY CAR ON AND THE REDUCED ENGINE POWER AND TRACTION CONTROL WARNING CAME ON. I IMMEDIATELY TURNED THE CAR OFF AND CHECKED THE OIL. IT WAS LOW BUT NO WARNING LIGHT TO INDICATE THIS ISSUE CAME ON (SAME AS IN THE PAST). I FAITHFULLY GET MY OIL CHANGED EVERY 3,000 MILES OR 3 MONTHS, WHICHEVER IS FIRST. MY OIL LIFE WAS AT 54% YESTERDAY AND I DID TAKE IT IN FOR AN OIL CHANGE THIS MORNING. IT IS OBVIOUS BASED ON OTHERS EXPERIENCES, THAT THIS IS A KNOWN ISSUE AMONGST 2009 IMPALA OWNERS. THE FACT THAT I DID NOT RECEIVE A WARNING WHEN I WAS ON A MAJOR HIGHWAY AND MY CAR SHUT OFF WHILE STILL IN MOTION, IS EXTREMELY SCARY AND IT TRAUMATIZED MY SON TREMENDOUSLY. I AM HOPING THAT SOME TYPE OF INVESTIGATION WILL BE INITIATED BECAUSE IT COULD RESULT IN SERIOUS INJURIES OR EVEN DEATH. *TR

CLIMBING UP ALPOWA GRADE ON HIGHWAY 12 IN WASHINGTON STATE, THE CHECK ENGINE LIGHT CAME ON, "ENGINE POWER IS REDUCED" CAME ON IN THE ODOMETER WINDOW. APPROXIMATELY 35 MILES LATER, BEYOND DODGE JUNCTION AND BEFORE STARBUCK TURNOFF, THERE WAS ANOTHER MESSAGE FLASHED IN THE ODOMETER WINDOW, "IGNITION SWITCH DISABLED. SERVICE ENGINE" THE ENGINE SHUT DOWN, AND THE POWER STEERING BECAME SUPER SLUGGISH. THE CAR SLOWED DOWN, AND WE WERE ABLE TO GET STOPPED ON THE SIDE OF THE ROAD. AT THIS POINT WHEN WE GOT THE CAR RUNNING AGAIN, THE CRUISE CONTROL WOULD NOT WORK. WHEN WE REACHED WALLA WALLA, WASHINGTON, WE STOPPED AT O'REILYS AUTO PARTS, HAD ONE OF THE PARTS SPECIALISTS COME OUT AND CHECK WHAT THE CODE WAS ON THE COMPUTER, AND FOUND OUT IT WAS THE ELECTRONIC THROTTLE SENSOR THAT IS DEFECTIVE. THIS IS A PILOT CAR ESCORT VEHICLE, MAKING THE HAZARD EVEN MORE DANGEROUS, BECAUSE HAD I BEEN TRAVELING WITH AN OVERSIZED LOAD, I COULD HAVE BEEN HIT BY THE SEMI PULLING THE LOAD, OR I COULD HAVE IMPACTED THE REAR OF THE LOAD, DEPENDING IF I WERE FOLLOWING OR LEADING. ALSO, HAD THAT HAPPENED WHILE ON A JOB, THE LOAD WOULD HAVE HAD TO STOP UNTIL ANOTHER PILOT CAR ESCORT VEHICLE COULD ARRIVE TO CONTINUE WITH THE LOAD. THIS IS A DANGEROUS THING TO HAVE SHUT OFF WHEN DRIVING IN AREAS THAT ARE NOT STRAIGHT. UNABLE TO CONTROL STEERING, BRAKES LESS THAN RESPONSIVE, AND POSSIBLE HAZARDS OF VEHICLES ONCOMING OR FOLLOWING US COULD BECOME IMPACT HAZARDS.

LAST NIGHT, I STARTED UP MY CAR AND IMMEDIATELY THE CAR STARTED TO SHUDDER PRETTY HARD. MY CAR STARTED CHIMING AND A SERVICE TRACTION CONTROL SHOWED UP ON MY DASH, FOLLOWED BY AN ENGINE POWER REDUCED. THE LIGHT INDICATOR FOR MY TC WAS LIT. I IMMEDIATELY TURNED THE CAR OFF AND TRIED TO RESTART IT. THE SAME THING HAPPENED AGAIN. I TURNED IT OFF AND WAITED 2 MINUTES BEFORE RESTARTING. IT STARTED FINE, WITH NO BAD INDICATIONS. THE CAR ALSO DROVE NORMALLY. A FEW HOURS LATER AS I WAS STARTING HOME, IT HAPPENED AGAIN. MY CAR WAS STILL PARKED AS BEFORE WHEN THE INDICATIONS SHOWED UP. SHUT OFF AND RESTARTED AND IT CLEARED OUT. NO PROBLEM ONCE I STARTED DRIVING. THIS MORNING WAS NO DIFFERENT. SO FAR, THIS ONLY HAS HAPPENED WHEN I WAS STARTING MY CAR UP. I HAVE BEEN FORTUNATE THAT THIS HASN'T HAPPENED TO ME WHILE THE CAR WAS IN MOTION- YET. OTHER PEOPLE WITH THIS PROBLEM HAVEN'T BEEN SO FORTUNATE. THERE HAS BEEN NO BAD WEATHER AT ALL. DRY AS A BONE. I BOUGHT THIS CAR IN 2010 KNOWING IT USED TO BE A RENTAL. I HAVE HAD NO PROBLEMS WITH IT UNTIL NOW. I TOOK MY CAR INTO MY CHEVY DEALERSHIP, WHO THOUGHT IT MIGHT BE THE THROTTLE BODY SENSOR. THEY ARE ORDERING THE PART IN, BUT I'M STILL SKEPTICAL IF THAT IS REALLY WHAT IS CAUSING IT. I HAVE HEARD THE SENSOR ON THE HUB ASSEMBLY COULD CAUSE THIS, AS WELL AS THE ACCELERATOR PEDAL SENSOR. FROM READING MULTIPLE FORUMS, MANY OWNERS HAVE HAD SCARY EXPERIENCES WITH THE CAR DECELERATING ON FREEWAYS OR OTHER DANGEROUS PLACES THAT COULD RESULT IN WRECKS AND PERSONAL HARM. THEY HAD TAKEN THEIR CARS IN MULTIPLE TIMES AND SHELLED OUT THOUSANDS TRYING TO FIX THIS PHANTOM GHOST PROBLEM. FRANKLY I AM AMAZED THERE HAS BEEN NO RECALL FOR THIS. I AM MOVING TO CA, AND I'M DRIVING THERE BY MYSELF IN LESS THAN TWO WEEKS. I CAN'T HAVE MY CAR TRY TO DO ME IN RIGHT NOW, NOR DO I HAVE ENDLESS AMOUNTS OF CASH TO FIX A MECH'S GUESS.

IT'S REALLY VERY SIMPLE MY ENGINE LIGHT IS ON ALONG WITH THE STABILITRAK LIGHT AS WELL AS THE CAR LOSING ALL POWER.

ALONG WITH GM BEING AT FAULT THE DEALERSHIPS ARE [XXX] THERE CUSTOMERS WHILE THEY GO THRU A LAUNDRY LIST OF ITEMS THEY THINK MIGHT BE THE PROBLEM FOR THESE CODES. I FOR ONE CANNOT AFFORD THE DEALERSHIP PRICES NOR WILL I PAY THESE SO CALLED EXPERTS GOOD MONEY AFTER BAD TO TRY AND FIX PROBLEMS THAT THEY REALLY HAVE NO IDEA AS TO WHAT'S CAUSING THEM. I ORIGINALLY BOUGHT THIS CHEVY B/C I WANTED AN AMERICAN CAR FOR A CHANGE, MAN WAS I WRONG. AS SOON AS I FIX THIS HEAP I WILL SELL IT BEFORE ANYMORE LIGHTS GO ON AND GO RIGHT BACK TO HONDA WHERE AT LEAST I KNOW THEY STAND BY THERE CARS AND IT RUNS WAY INTO THE SIX FIGURES BEFORE ANY REAL PROBLEMS OCCUR. I'M ONE OF THE LITTLE GUYS THAT BAILED OUT GM AND BY THE WAY WERE STILL PAYING TAXES FOR THAT BAILOUT. HOW ABOUT IT GM, DON'T YOU CARE ABOUT US AT ALL? *TR PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

WHAT HAPPENED IS THE VEHICLE TRACTION CONTROL TRIGGERED AND REDUCED THE CARS FUNCTIONALITY AND SPEED. IT CLEARED ITSELF, BUT WHAT CONCERNS ME IS THIS PROBLEM IS PREVALENT IN GM CHEVROLET VEHICLES RANGING FROM 2005 TO 2011. IT IS LISTED MANY TIMES HERE IN YOUR DATA BASE TO YOUR ORGANIZATION. OUR LIVES AND SAFETY ARE INVOLVED HERE. FOCUSING ON CHARGING A FEE TO DO AN INVESTIGATION IS DEPLORABLE. LIVES ARE AT STAKE HERE. THIS SHOULD NOT BE ANOTHER AMERICAN AFTER THE FACT OCCURRENCE OR EVENT. WHAT HAPPENED TO PROACTIVE RESPONSIBILITY. THESE AMERICAN CAR MAKERS PRODUCE JUNK CARS AND THE CONSUMER CONSTANTLY GET STIFFED WITH LEMONS. STATES LEMON LAWS? NOTHING BUT AMERICAN LEMONS ARE ROLLING OFF OF THE PRODUCTION LINES. YOU THINK, THIS MAY BE WHY OTHER COUNTRIES WILL NOT BUY OUR PRODUCTS. THERE IS NO RELIABILITY IN WHAT IS PRODUCED OR MANUFACTURED AND THE CUSTOMER SERVICE IS LIP SERVICE. NON - EXISTENT WITH THESE CAR DEALERS AND PURE SALES RHETORIC. YOUR SITE READS: THE INFORMATION YOU PROVIDE WILL BE USED TO IDENTIFY POTENTIAL SAFETY-RELATED DEFECTS OR DETERMINE THE ADEQUACY OF EXISTING SAFETY RECALLS. I CAN'T AFFORD THE REPAIRS, PAY FOR AN INVESTIGATION AS WELL. I AM NOT PLEASED WITH HOW THE BALL KEEPS GETTING PASSED OR DROPPED. NHTSA THESE POORLY PRODUCED WEAPONS WEIGH TONS. ROLLING DOWN THE POORLY MAINTAINED HIGHWAYS AND STREETS OF THIS COUNTRY ENDANGERING US ALL LIFE AND LIMB. MY VEHICLE HAS THE SAME PROBLEM WITH THE TRACTION CONTROL THAT FORCES MY CAR TO BRAKE , PULL TO THE RIGHT AND SLOW ENOUGH TO ENDANGER MY WELL BEING. I'M TRULY SCARED AND CONCERNED HERE AND THE REPAIRS AND CODE LIGHTS AREN'T RELIABLE. ONLY THE REPAIR SHOPS ARE WINNING. THE PROBLEM KEEPS REPEATING AFTER THOUSANDS ARE SPENT TO KEEP THE CAR RUNNING. I NEED THIS CAR FOR WORK. IF IT CANT GET ME THERE THEN THEY WILL COME AND TAKE THE JUNK BACK I AM TRYING TO MAINTAIN. THANK YOU *TR

BY THE TIME I GOT THERE AND STARTED THE ENGINE IT WAS RUNNING NORMALLY EXCEPT FOR THE "SERVICE ENGINE SOON" LIGHT WAS LIT. I TOOK IT TO THE NEAREST CHEVROLET DEALERSHIP WHO IMMEDIATELY STATED IT WAS A FAULTY ELECTRONIC THROTTLE CONTROL AND WOULD COST $580 TO REPLACE. I SEARCHED ON-LINE AND FOUND DOZENS OF COMPLAINTS EXACTLY LIKE THIS ONE FOR 2008-2012 MODEL IMPALAS'.

THE CAR THEN STOPPED ACCELERATING AND DROPPED TO 45 MPH IMMEDIATELY. I WAS NEARLY REAR ENDED WITH MY SON IN THE CAR.

WHEN I PRESSED DOWN ON MY ACCELERATOR PEDAL (SPEED LIMIT WAS INCREASING FROM 50MPH TO 65MPH), A MESSAGE OF "STARTING DISABLED. SERVICE THROTTLE" CAME UP ON THE DASH. THE ACCELERATOR PEDAL AND STEERING WHEEL COMPLETELY LOCKED UP AND THE CAR STARTED TO DECELERATE. I WAS ABLE TO FORCE THE STEERING WHEEL IN ORDER TO TURN ONTO A SIDE STREET (NARROWLY AVOIDING A CAR STOPPED IN THE LEFT LANE TO TURN) AND PARK THE VEHICLE IN A LOCATION OUT OF THE MAIN LANE OF TRAFFIC. HAD THIS SIDE STREET NOT BEEN THERE AT THAT EXACT MOMENT, THE POSSIBILITY OF A CRASH WOULD BE VERY LIKELY AS STEERING WAS UNRESPONSIVE AND I MAY HAVE BEEN REAR-ENDED DUE TO THE SUDDEN LOSS OF ENGINE POWER. *TR

I WAS DRIVING DOWN THE HIGHWAY, AND THE TRACTION CONTROL LIGHT CAME ON AND THE REDUCED ENGINE POWER LIGHT CAME ON. I DROVE A FEW MILES FURTHER GOING ABOUT 65 MILES AND HOUR, AND THE ENGINE DIED IN THE MIDDLE OF THE HIGHWAY. I HAD TO PULL THE CAR OFF THE ROAD WITH NO POWER STEERING (I WAS STILL ROLLING THANKS TO MOMENTUM) SO I WOULDN'T GET HIT BY ANOTHER CAR. AFTER I SAT ON THE SIDE OF THE ROAD FOR A FEW MINUTES, I WAS ABLE TO START IT AGAIN AND DRIVE IT ABOUT 10 MILES BACK HOME. OUR REPAIRMAN SAID THE THROTTLE MOTOR SIGNAL CAME UP WHEN HE PLUGGED IT IN TO THE COMPUTER, SO WE SPENT THE $280 TO REPLACE IT. IT WORKED FINE FOR ABOUT 4 DAYS, AND THEN THE TRACTION LIGHT AND AND REDUCED ENGINE POWER LIGHT CAME ON AGAIN A FEW DAYS AGO.

I WAS DRIVING THROUGH A HILLY/ CURVY AREA OF ROAD WHEN MY REDUCED ENGINE POWER, TRACTION CONTROL, AND THROTTLE BODY DISABLED MESSAGE POPPED UP. JUST THEN I HAVE NO POWER, NO BRAKES AND NO STEERING,AT ALL! I ALMOST CRASHED WITH MY TWO KIDS IN THE CAR! UPON LOOKING UP THIS ISSUE I FIND THAT IT IS A VERY COMMON ISSUE IN IMPALAS. SOME PEOPLE HAVE HAD THIS ISSUE WHILE PASSING CARS, OR THE FREEWAYS AND MORE. TO ME THIS IS QUITE A SAFETY CONCERN SINCE YOU HAVE NO POWER TO DO ANYTHING...NOTHING AT ALL.

THIS THE SECOND TIME THIS HAS HAPPENED. WIFE WAS DRIVING DOWN THE FREEWAY WHEN TRACTION CONTROL AND CHECK ENGINE LIGHTS CAME ON. CAR WENT INTO REDUCED POWER MODE AND FINALLY DIED WHILE STILL MOVING. LOST POWER STEERING AND FINALLY BROUGHT CAR TO A STOP ON LEFT INSIDE OF EXPRESSWAY. AFTER A SHORT TIME SHE WAS ABLE TO RESTART THE CAR AND LIMP HOME. NOTE THAT THE CRUISE CONTROL WAS ON, BUT I DO NOT KNOW IF IT WAS SET. HAD THE CODES READ THAT INDICATED A THROTTLE POSITION SENSOR CAUSED THE FAULT. THERE ARE TWO SENSORS WHICH HAVE TO AGREE AND IF THEY DON'T CAR WILL GO INTO REDUCED POWER MODE. WHEN SHE GOT HOME I FOUND ONLY THE CHECK ENGINE LIGHT ON. I HAVE IN THE PAST MOVED THE WIRES ON THE BRAKE FLUID SENSOR TO GET THE CHECK ENGINE LIGHT TO GO OFF. NOT KNOWING EXACTLY HOW ALL OF THESE DIFFERENT SYSTEMS ARE TIED TOGETHER, I TEND TO THINK THAT THE CARS COMPUTER IS THE PROBLEM WHICH SETS OFF ALL THE DIFFERENT WARNING LIGHTS ON THE DASH. I WENT TO THE CHEVY DEALERSHIP AND THE SERVICE ADVISOR ASKED IF THIS WAS A RECALL ISSUE. I THOUGHT THIS WAS SOME WHAT STRANGE. AFTER READING COMPLAINTS ON THE NET I CAN SEE WHY SHE MIGHT HAVE THOUGHT IT WAS A RECALL ISSUE. THE THROTTLE BODY PART IS $300 DOLLARS PLUS LABOR RATE OF $105/HR. AS OF NOW I CANNOT FIND ANY RECALLS FOR THIS ISSUE. NHTSA NEEDS TO LOOK AT THIS PROBLEM BECAUSE THE LOSS OF STEERING WITH ALL SYSTEMS DUE TO MOTOR STALLING WHILE IN MOTION IS A HAZARD TO EVERYONE. *TR

I AM HAVING PROBLEMS WITH MY 2009 CHEVY IMPALA, IT STARTED AT 43K, THE ACCELERATION PEDAL WAS CHANGED WHEN THE REDUCED ENGINE POWER/SERVICE TRACTION CONTROL CAME ON. THEN AGAIN AT 100K SAME PROBLEM, THIS TIME THE DEALERSHIP TOLD ME IT WAS A BAD THROTTLE POSITION SENSOR, THE THROTTLE BODY NEEDED TO BE CHANGED. I CHANGED IT, BUT IT CAME BACK AGAIN LESS THEN 3K MILES. I REPLACED THE THROTTLE BODY AGAIN. 3K LATER SAME THING. THE PROBLEM IS WHEN IT IS RAINING THE THROTTLE SENSORS GO NUTS. I TOOK THE CAR TO ADVANCE AUTO AND READ THE CODES, SAME AS BEFORE, P0121, P2176, THROTTLE POSITION SENSOR. ONCE IN A WHILE YOU CAN REMOVE THE BATTER LINES AND UNPLUG THE THROTTLE BODY AND MASS AIR FLOW SENSOR TO GET IT TO RESTART. OTHER TIMES YOU HAVE TO GO TO ADVANCE OR AUTOZONE TO CLEAR THE CODES IN ORDER TO GET IT TO RUN LONG ENOUGH FOR A SUNNY DAY. I HAD ONE OCCURRENCE WERE THE CAR WOULD NOT START AND IT SAID SERVICE THROTTLE POSITION. THE THROTTLE SENSOR NEEDS TO BE RECALLED BEFORE SOMEONE GET KILLED. I HAVE RENAMED MY CAR TO THE FORD IMPALA. FOUND ON THE ROAD DEAD IMPALA. *TR

WHILE MERGING ONTO A TWO LANE HIGHWAY MY IMPALA SUDDENLY LOST POWER AND I RECEIVED A "LOW ENGINE POWER" WARNING AND THEN " SERVICE TRACTION CONTROL" THE CHECK ENGINE LIGHT COMES ON AND THE CAR RUNS ROUGHLY AT REDUCED POWER - YOU NEED TO PULL OVER AND SHUT THE CAR OFF UNTIL YOU CAN START IT AGAIN. THIS IS A VERY DANGEROUS ISSUE THAT GM REFUSES TO ACKNOWLEDGE. IN THIS INSTANCE I HAD MY DAUGHTER IN THE CAR - I ALSO LOST THE POWER BRAKES. I HAVE BEEN TO TWO CHEVROLET DEALERS AND A BUICK DEALER BECAUSE THIS HAS HAPPENED SEVERAL TIMES OVER THE PAST YEAR AND A HALF. THEY REPLACED MY THROTTLE BODY, OIL SENSOR, BATTERY AND SOMETHING ELSE AND CHARGED ME OVER $2000 FOR THE THREE VISITS AND I AM STILL EXPERIENCING THE ISSUE. I HAVE ALSO BEEN TO A LOCAL REPAIR SHOP AND HAD THE WIRING HARNESS CHANGED AND HAD SEVERAL DIAGNOSTICS DONE. AFTER ALL THIS THE PROBLEM STILL EXISTS. I NORMALLY DON'T WRITE LETTERS BUT, THIS IS A VERY DANGEROUS SITUATION AND MANY OTHERS ARE EXPERIENCING THE SAME THING BASED ON THE MESSAGE BOARDS I HAVE READ. MY CONCERN IS THAT GM REFUSED TO HELP OR ISSUE A RECALL. MY FEAR IS THAT SOMEONE GETS SERIOUSLY HURT OR KILLED BEFORE GM ANSWERS FOR THIS. THIS IS NOT GOOD FOR GM. MY HOPE IS THAT SOMEONE FINALLY ADDRESSES THIS ISSUE BEFORE SOMEONE IS KILLED. IN MY LAST COMMUNICATION WITH GM - I WAS TOLD TO TAKE MY CAR TO A DEALER FOR A DIAGNOSTIC AT MY OWN EXPENSE.

A COUPLE OF PEOPLE SAID THEIR CARS ACTUALLY CUT OFF ON THEM WHILE GOING DOWN THE HIGHWAY AT A HIGH RATE OF SPEED. ONE WAS INVOLVED IN AN ACCIDENT.

EVEN THOUGH I WAS ABLE TO PULL OFF THE SIDE, IT WAS NOT IN A SAFE PLACE AND TRAFFIC WAS GOING BY AT THE SPEED OF 55-60 MPH AND I WAS BARELY OVER THE WHITE LINE. I CALLED A TOW TRUCK, AND HAD IT TOWED TO MY MECHANIC. THIS HAPPENED AT 4:15 ON A FRIDAY AFTERNOON. MY MECHANIC DIDN'T LOOK AT IT UNTIL MONDAY AND COULD NOT FIND ANYTHING WRONG WITH IT. HE DROVE IT ALL OVER AND HE CHECKED EVERYTHING HE COULD THINK OF. I TRUST THIS MECHANIC. HE DID SAY THAT HE WAS AFRAID HE WOULD HAVE TO SEND ME TO THE DEALER TO HAVE IT LOOKED AT. I CAME HOME, GOOGLED THE PROBLEMS AND ENDED UP AT EDMUNDS.COM IN A FORUM FOR CHEVY OWNERS WITH THIS ISSUE. WHILE NO ONE WAS HURT THIS TIME, THAT IS JUST A BLESSING.

HOW MUCH MONEY AND TIME WILL I SPEND TAKING THIS TO A DEALER WHO DOESN'T KNOW ABOUT THE PROBLEM AND WON'T DIAGNOSE IT CORRECTLY THE FIRST TIME? AMERICA WANTS AMERICANS TO BUY AMERICAN MADE PRODUCTS.
