CAR CONTINUOUSLY GETS A REDUCED POWER MESSAGE AND GOES DOWN TO 25 MPH. IN MID JANUARY DID THE SAME THING, BUT STALLED ON I90 OHIO TURNPIKE. ALMOST HIT BY A SEMI TRUCK. HAVE HAD THE CAR IN THE SHOP NO LESS THAN 5 TIMES FOR THE SAME PROBLEM. AT GM AND NON GM REPAIR SHOPS. WE HAVE HAD THIS SAME REDUCED POWER ON CITY ROADS, AND THE HIGHWAY, IT SEEMS ALWAYS WHEN IT IS WET, RAINY OR SLUSHY. IT REALLY APPEARS TO BE A WATER CAUSES THE PROBLEM. WE HAVE PAID FOR TWO SETS OF THROTTLE BODY, SPEED CONTROL SENSOR AND HARNESSES. THE PROBLEM CONTINUES TO PERSIST AND APPEARS TO BE DANGEROUS.

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...

I CRASHED HEADING DOWN A HILL .I CRASHED INTO A TELEPHONE POLE AFTER MY CAR SUDDENLY REVVED UP,GAINED SPEED AS I HEADED TOWARDS A TELEPHONE POLE ,WITH LOSS OF POWER STEERING ,BRAKES BECAUSE MY CAR QUIT AFTER GAINING SPEED DUE TO THE RPMS AMPING UP ON THEIR OWN AND GOING DOWN A HILL. WHEN I HIT THE POLE,THE TELEPHONE LINES SNAPPED AND I WAS TRAPPED IN THE CAR BECAUSE THEY LANDED ON MY DRIVER WINDOW AND WERE SHOOTING OUT SPARKS AS IF THEY WERE ROMAN CANDLES AND A FIRE STARTED ON THE RIGHT SIDE OF MY CAR IN SOME PINE STRAW. WHEN THE FIREMEN WAS ABLE TO GET ME OUT OF THE CAR HE CAME TO THE PASSENGER SIDE AND BY THEN I HAD TAKEN MY SEAT BELT OFF AND THE FIREMAN ADVISED ME TO GET OUT OF THE PASSENGER SIDE IF I WAS ABLE AND I TOLD HIM THAT...

THIS HAS BEEN HAPPENING FOR SEVERAL YEARS, AND HAPPENED AGAIN YESTERDAY..... PULLED OUT ONTO 4 LANE DIVIDED HIGHWAY AND TRACTION CONTROL LIGHT CAME ON, DASH SAID "ENGINE POWER REDUCED", BUT DID NOT SEEM TO BE SIGNIFICANTLY LOW ON POWER. DROVE ABOUT 5 MILES DOWN THE ROAD, THEN CAR SUDDENLY DIED. WAS ABLE TO PULL OVER TO SIDE OF THE ROAD (WITH THREE SMALL CHILDREN IN THE VEHICLE), TRIED TO RESTART THE CAR BUT DISPLAY SAID "STARTING DISABLED, SERVICE THROTTLE". WAITED ABOUT 5 MINUTES AND CAR RESTARTED. WAS ABLE TO DRIVE HOME, NO REDUCED POWER BUT CHECK ENGINE LIGHT REMAINED ON. I HAVE SEEN MANY COMMENTS ONLINE FROM OTHERS WHO OWN SIMILAR GM VEHICLES THAT HAVE HAD SIMILAR ISSUES. WE HAVE ALSO HAD SIMILAR ISSUES WITH OUR 2011 SUBURBAN, ALTHOUGH NO STALLING. THERE SHOULD BE AN IMMEDIATE RECALL FOR ALL 2008 - 2011 GM VEHICLES TO REPAIR THIS ISSUE, MOST LIKELY...

POWER REDUCES IN HEAVY TRAFFIC. IF I SLOW BECAUSE OF TRAFFIC IT JERKS LIKE BRAKES ARE STILL ENGAGED. ACTS LIKE TRANSMISSION GOING OUT. THIS CAN CAUSE SOMEONE TO GET RUN INTO FROM BEHIND. THERE WAS A RECALL EARLIER THIS YEAR. THE MILEAGE WAS NOT ENOUGH TO COVER MY VECHILE. THERE SHOULD BE NO MILEAGE LIMIT. *TR

JUST KEEPS SHOWING WARNING SIGNALS A TRACTION CONTROL. THE FRONT LEFT STRUT COVER IS CORRODED WHICH WAS TOLD TO ME EVENTUALLY THE STRUT WILL COME THROUGH THERE. SHOWING NO SIGNS OF THE FAN WORKING TO COOL THE CAR DOWN WHICH THEN READS ENGINE TOO HOT TURN OFF AC. *TR

WHILE DRIVING, THE CAR IN MOTION IT COMPLETELY LOSES POWER. HAVE EXPERIENCED THIS WHILE ON HIGHWAY, INTERSTATE, AND IN TOWN ROADS. SO PROBLEM OCCURS AT ANY SPEED, AND RESULTS IN VEHICLE COASTING TO A STOP AS THE STEERING AND BRAKES STOP WORKING TOO. HAS HAPPENED TO ME HUNDREDS OF TIMES AS WE CAN NOT PIN POINT PROBLEM, AND HAS REPLACED NUMEROUS DIFFERENT PARTS TRYING TO SOLVE IT. WHEN POWER LOSS OCCURS THERE IS VERY LITTLE TO NO TIME AT ALL FOR DRIVER TO COAST & STEER VEHICLE & OCCUPANTS TO SAFETY AREA ON SIDE OF ROAD. THE DASHBOARD INFORMATION CENTER WILL STATE "STARTING DISABLED, SERVICE THROTTLE" ALSO ENGINE POWER REDUCED" AND "SERVICE STABLITRAK." A NEW THROTTLE HAS BEEN PUT IN VEHICLE AND STILL DOES SAME THING. OVER THE YEAR IVE BEEN DEALING WITH THIS ISSUE IVE NOTICED IT DOES IT MORE IN WARM WEATHER. AFTER VEHICLE COAST TO A STOP...

WHILE DRIVING OIL PRESSURE LOW STOP ENGINE COMES ON IN MY DIC EVEN THOUGH MY OIL IS PERFECTLY FINE MY REAR TURNING SIGNAL IS NOT FLASHING BUT IS LIT AND WORKING FOR EVERYTHING ELSE MY TEMPERATURE GAUGE SHORTS OUT AT TIMES EVEN AFTER I REPLACED THE SENSOR PASSENGER AIR BAG OFF EVEN WITH PASSENGER INSIDE NHTSA RECALL NUMBER 16V507 NHTSA RECALL NUMBER 14V355 I BELIEVE THE TRUE PROBLEM IS THE BCM THE DOOR ACTUATORS ARE FAULTY

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. THE CONTACT STATED THAT SEVERAL WARNING INDICATORS ILLUMINATED, INCLUDING THE ABS, AIR BAG, SERVICE TRACTION CONTROL, AND STABILITY CONTROL. THE CONTACT ALSO HEARD BANGING NOISES COMING ROM THE REAR OF THE VEHICLE, RESULTING IN ROUGH DRIVING. THE MANUFACTURER WAS NOTIFIED AND ADVISED THE CONTACT TO TAKE THE VEHICLE TO A DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS UNKNOWN.

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. WHEN THIS HAPPENS, MY VEHICLE LOSES SPEED AND CANNOT ACCELERATE ABOVE 40MPH - DANGEROUS, ESPECIALLY ON AN INTERSTATE. 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.

THE RADIATOR FAN STOP WORKING DO TO ELECTRICAL PROBLEM I CHANGE SENSORS AND RELAYS N STILL WON'T WORK I HAD AUTO SHOP TEST THE FAN AND THE FANS WORKS. IT STOP WORKING ON ITS ON

THE VEHICLE SHUT DOWN AND I CANNOT START IT BECAUSE OF THE IGNITION SWITCH CAUSING THE ENTIRE VEHICLE TO BECOME INOPERABLE. I WAS PULLING UP IN MY DRIVEWAYWHEN THE VEHICLE SHUT DOWN.

EARLIER THIS YEAR MY CAR STARTED FLASHING A "REDUCE ENGINE POWER" AND "SERVICE TRACTION CONTROL" TOGETHER. MY CAR SOUNDED LIKE IT WAS WORKING HARDER TOO BUT I WAS CITY DRIVING LESS THAN 30MPH SO I DIDN'T OTHERWISE NOTICE PROBLEMS. THIS HAPPENED RARELY. A FEW MONTHS LATER I WAS ON THE FREEWAY JUST GETTING ON (FLAT ROAD) AND THE WARNINGS CAME ON SUDDENLY. THEN AS I GOT OVER 40MPH, MY CAR ENGINE SHUT DOWN AND MY STEERING WHEEL LOCKED. LUCKILY I WAS ABLE TO MAKE A SLIGHT TURN OFF MY WHEELS ENOUGH TO GET TO THE SIDE OF THE ROAD. MY CAR FLASHES THESE RANDOMLY AFTER RANDOM LENGTHS OF TIME OF THE CAR BEING ON AND DRIVEN AND IT'S ALMOST A DAILY OCCURRENCE. I'VE SEEN ONLINE NO ONE HAS BEEN ABLE TO SOLVE THE ISSUE.

THE IMPALA DISPLAYS SERVICE TRACTION CONTROL FOLLOWED BY ENGINE POWER REDUCED. THROWS A CODE FOR THROTTLE BODY SENSOR, BUT THAT DOES NOT FIX THE ISSUE. ACCELERATOR PEDAL POSITION SENSOR IS ANOTHER REASON THEY SAY, WHICH ALSO DOES NOT FIX THE ISSUE. MY CAR HAS SHUT OFF ON ME GOING DOWN THE INTERSTATE, ON A HIGHWAY, AND AND OVER A HILL. IT SHUTS DOWN AND SAYS 'STARTING DISABLED, SERVICE THROTTLE' WITH NO WARNING AT ALL. SEVERAL PEOPLE HAVE HAD THE SAME EXACT PROBLEM AND NO ONE SEEMS TO KNOW HOW TO FIX IT. THEY SAY WIRING BUT IT NEVER FIXED ANYTHING.

CAR DRIVES FOR 15 MINUTES THEN DISPLAY AN "ENGINE POWER REDUCED" AND "SERVICE TRACTION CONTROL" LIGHT. CAR HESITATES TO ACCELERATE THE EVENTUALLY CUTS OFF AFTER A "SERVICE THROTTLE BODY LIGHT" COMES ON. CAR CUT OFF ON THE HIGHWAY AT 70MPH. WHENEVER THERE IS A PROBLEM WITH THE CAR THESE LIGHTS COME ON. IT DOESN'T SPECIFY WHAT THE ACTUAL PROBLEM IS.

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. WHILE DRIVING 70 MPH, THE TRACTION CONTROL INDICATOR ILLUMINATED AND THE MESSAGE "LOSING ENGINE POWER" APPEARED. AFTERWARDS, THE STEERING WHEEL SEIZED AND THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE CONTACT APPLIED THE EMERGENCY BRAKE AND THE VEHICLE STOPPED. THE CONTACT STATED THAT THE VEHICLE WAS ALSO INCLUDED IN NHTSA CAMPAIGN NUMBER: 16V507000 (AIR BAGS). THE VEHICLE WAS TAKEN TO YEMM CHEVROLET BUICK GMC CHRYSLER DODGE JEEP RAM (2195 N HENDERSON ST, GALESBURG, IL 61401, (309) 271-0106), BUT NO ASSISTANCE WAS PROVIDED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURES. THE FAILURE MILEAGE WAS 131,000.

THE ENGINE WILL SHUT OFF. THEN THE STEREO WILL TURN OFF FOR A SECOND THEN COME BACK ON AND DISPLAY SERVICE STABILITRAK. THE VEHICLE WAS STATIONARY AT A STOPLIGHT. THE ENGINE HAS ALWAYS COME BACK ON WHEN TRYING TO RESTART IT WITH THE KEY.

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.

BAD SOLENOID IN TRANSMISSION CAUSES CAR TO JERK UPON ACCELERATION. TRANSMISSION SLIPS. USUALLY HAPPENS TAKING OFF FROM A STOP WITH A SLOW ACCELERATION. FEELS LIKE BEING REAR ENDED AND CAN CAUSE SLUGGISH ACCELERATION. PROBLEM NEEDS TO BE ADDRESSED WITH A RECALL AS MANY OTHER IMPALA DRIVERS HAVE EXPERIENCED THIS SAME ISSUE. ISSUE HAS HAPPENED AT LEAST 9 TIMES WITHIN A 6 WEEK PERIOD.

I WAS DRIVING ALONE ON THE HIGHWAY AND NOTICED THAT THE RMP GAUGES WAS GOING UP AND DOWN, THEN SUDDENLY A MESSAGE ON THE DASH READ, SERVICE TRACTION CONTROL, THEN A FEW SECONDS LATER ANOTHER MESSAGE READ, ENGINE POWER REDUCED AND THE CAR WOULD NOT PICK UP ANY SPEED. THIS WAS VERY SCARY AND CONFUSING BECAUSE THE NEXT DAY I HAD NO ISSES BUT HAS NOW IT DID THE SAME THING TODAY. PLEASE HELP.

"LOW OIL PRESSURE LIGHT, SHUT OFF ENGINE" KEEPS COMING ON. OIL IS FULL. SO FAR I HAVE AIR BAG LIGHT, TRACTION CONTROL LIGHT, ENGINE LIGHT, ENGINE SPEED REDUCED LIGHT ALL ON! HOW ARE THESE AUTO'S NOT BEING RECALLED! I WILL NEVER OWN A CHEVY AGAIN! UNSAFE PIECE'S OF JUNK!

WHILE DRIVING ON THE INTERSTATE AT 70MPH, AIR BAG LIGHT, ENGINE LIGHT AS WELL AS TRACTION CONTROL LIGHT CAME ON. FELT AS IF BRAKES WERE ON. DASH READ "SERVICE TRACTION CONTROL" & "ENGINE SPEED REDUCED". 140,000 MILES

ENGINE SUDDENLY DIED WHILE I WAS DRIVING. I PULLED OVER TO THE SIDE OF THE ROAD AND IT ALMOST CAUSED AN ACCIDENT BECAUSE POWER STEERING WENT OUT. I WAS ABLE TO START THE ENGINE BACK UP NO PROBLEM. I HAD A CHECK ENGINE LIGHT ON BECAUSE OF THE OIL PRESSURE SENSOR. I HAD JUST REPLACED IT THE DAY BEFORE. I SUSPECT IT HAD SOMETHING TO DO WITH THAT, BUT IM NOT SURE. IF I WAS ON THE HIGHWAY IM PRETTY SURE I WOULD HAVE GOTTEN IN AN ACCIDENT. THIS ISNT THE FIRST TIME THIS CAR HAS ALMOST CAUSED AN ACCIDENT BECAUSE OF FAULTY CAR PARTS, THIS CAR IS DANGEROUS.

WHAT HAS TO HAPPEN BEFORE SOMETHING IS DONE ABOUT THIS PROBLEM ? TRACTION CONTROL LIGHT AND REDUCE ENGINE POWER LIGHT COMES ON GOING DOWN THE INTERSTATE AND THE CAR SHUTS DOWN AND YOU HAVE TO TRY AND GET CAR PULLED OVER TO THE SIDE OF THE ROAD WITHOUT HITTING SOMEONE OR GETTING HIT . THIS IS A VERY COMMON PROBLEM WITH THIS VEHICLE AND NOTHING IS BEING DONE ABOUT IT . I WOULD REALLY LIKE A RESPONSE ON THIS PROBLEM . THIS HAPPENS A LOT SO YOUR DATE YOU WANT INCIDENT HAPPENING IS REALLY NOT RIGHT .

WHILE THE VEHICLE WAS IN MOTION ON DRY PAVEMENT, THE TRACTION CONTROL LIGHT CAME ON, FOLLOWED BY THE CHECK ENGINE LIGHT THEN THE CAR STALLED AND HAD TO BE BE EASED OFF THE HIGHWAY. TRIED TO RESTART THE VEHICLE SEVERAL TIMES. AFTER IT SAT FOR A COUPLE OF MINUTES TRIED ONE MORE TIME AND THE CAR RESTARTED AND DROVE HOME PERFECTLY. RESEARCHED THE ISSUE ONLINE, AND THERE ARE ENTIRE FORUMS IN EDMUNDS DEDICATED TO THIS VERY PROBLEM. DEFINITELY A SAFETY ISSUE WITH THIS VEHICLE.

FOR THE LAST TWO DAYS, I HAVE DRIVEN MY VEHICLE. EVERY TIME I WOULD DRIVE OVER 40 MPH, THE ENGINE WOULD LOCK UP. THE VEHICLE WOULD JERK AND SHAKE BACK AND FORTH. THE CAR WOULD DO THIS EVERY TIME I WENT OVER 40 MPH, NO MATTER IF I WAS DRIVING ON A HIGHWAY OR ROAD OR COMING TO A STOP AT A RED TRAFFIC LIGHT. WHENEVER THIS HAPPENED, THE CHECK ENGINE LIGHT AND THE TRACTION CONTROL LIGHT WOULD STAY ON. THIS PROBLEM STARTED WEEKS AFTER I HAD AN AUTO ACCIDENT. *TR

THE CAR WOULD DO THIS EVERY TIME I WOULD TRY AND DRIVE OVER 40 MPH, NO MATTER THE ROADWAY OR STOP AT AN INTERSECTION. WHENEVER THIS HAPPENED, THE CHECK ENGINE LIGHT WOULD STAY ON. A MONTH BEFORE THIS PROBLEM STARTED, MY FATHER HAD BEEN DRIVING THE CAR AND HAD AN AUTO ACCIDENT. *TR

MY CAR'S ENGINE POWER WAS SEVERELY REDUCED SUDDENLY WHEN I WAS DRIVING ON INTERSTATE HIGHWAY 275 NORTH IN TAMPA, FL. A MESSAGE SHOWED ON THE DASH: " REDUCED ENGINE POWER, SERVICE TRACTION CONTROL" AND THE CHECK ENGINE LIGHT WAS ON. THIS HAPPENED TODAY AROUND 7 PM ON OCT 30, 2016. MY CAR IS A CHEVY IMPALA 2009. I SEARCHED ONLINE AND FOUND THOUSANDS OF MESSAGES ABOUT THE SAME ERROR MESSAGE OF REDUCED ENGINE POWER ON MANY MODELS OF GM CARS INCLUDING IMPALA, MALIBU, TRAILBLAZER, SILVERADO. THIS WORRIES ME VERY MUCH AS SO MANY SAME ERROR MESSAGES AND ENGINE PROBLEMS HAPPENED ON SO MANY GM CARS. MY RESEARCH SHOWS THAT GM HAS DONE NOTHING TO RESOLVE THIS PROBLEM YET. SO THIS IRRESPONSIBILITY OF GM ON THIS SPECIFIC ISSUE PUT THE LIVES OF HUNDREDS OF THOUSANDS OF DRIVERS IN DANGER. I HOPE NHTSA LOOKS INTO THIS PROBLEM AND PRESSURE GM TO ISSUE...

WHILE DRIVING THE CHECK ENGINE LIGHT AND TRACTION CONTROL LIGHT COMES ON AND REDUCE ENGINE POWER READS ACROSS THE SCREEN. CAR SLOWS TO 45 MILES AN HOUR AND TURNS OFF. I HAVE HAD THE THROTTLE REPLACED AND THE THROTTLE BODY REPLACED. THE PROBLEM STILL ON GOING....?

I WAS DRIVING AND SUDDENLY A SYMBOL FOR TRACTION STABILITY CAME ON AND THEN A WARNING SAYING LOW ENGINE POWER.

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE STALLED AND THE TRACTION CONTROL WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL.

TL* TAKATA RECALL. THE CONTACT OWNS A 2009 CHEVROLET IMPALA. THE CONTACT HAD NOT EXPERIENCED A FAILURE WITH THE VEHICLE UNTIL IT WAS REPAIRED PER NHTSA CAMPAIGN NUMBER: 14V355000 (ELECTRICAL SYSTEM). SHORTLY AFTER THE DEALER'S REPAIR, THE CHECK ENGINE WARNING LIGHT RANDOMLY ILLUMINATED AND THE VENT CONTROLS FAILED TO PROPERLY WORK. IN ADDITION, THE KEY FOB FAILED TO LOCK AND UNLOCK AT DIFFERENT POINTS IN TIME. THE CONTACT NOTIFIED THE DEALER AND THEY WERE UNABLE TO PROVIDE A SOLUTION FOR THE VARIOUS ELECTRICAL FAILURES. IN ADDITION, THE BRAKES WERE SLOW TO RESPOND AND THE DEALER REPLACED THE ROTORS, WHICH DID NOT PREVENT THE FAILURE. THE CONTACT WAS INFORMED THAT THE BRAKE ACTUATOR NEEDED TO BE REPLACED. THE REPAIRS FOR THE BRAKE SYSTEM DID NOT PREVENT THE FAILURE. THE CONTACT LATER RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 16V507000 (AIR BAGS, ELECTRICAL SYSTEM). THE PARTS WERE NOT AVAILABLE.

REDUCED ENGINE POWER APPEARED FOLLOWED BY CHECK TRACTION CONTROL. THEN SYMBOL FOR CHECK TRACTION CONTROL AND ENGINE COMPLETELY IN PASSING LANE ON INTERSTATE 80. CHECK ENGINE SYMBOL ALSO LIT, CAR COMPLETELY DIED AND WOULD NOT RESTART. APPROX 15 MIN LATER, IT DID START WITH CHECK ENGINE SYMBOL LIGHTED.

CAR IS CURRENTLY AT 134K MILES AND JUST GAVE ME A "REDUCED POWER ENGINE", "CHECK TRACTION CONTROL", AND A CHECK ENGINE LIGHT. I GOOGLED AROUND AND CAME ACROSS A LOT OF CHEVY IMPALAS AROUND THE SAME YEAR (07-10) ARE HAVING THE SAME PROBLEM. IT SEEMS TO BE SOMETHING WITH THE "ACCELERATOR PEDAL POSITIONER PEDAL SENSOR. ALSO READING INTO IT, IT CLAIMS THAT THIS PROBLEM CAN CAUSE THE CAR TO SUDDENLY STOP FROM 60MPH ALL THE WAY DOWN TO 20 OR ZERO. THIS IS EXTREMELY DANGEROUS AND NEEDS TO BE LOOKED INTO BEFORE SOMEONE IS HURT OR KILLED.

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...

THIS PROBLEM STARTED 2 YEARS AGO. MY CAR WOULD GIVE ME A WARNING "SERVICE TRACTION CONTROL. ENGINE POWER REDUCED." THEN THE CAR WOULD SHUT OFF. I TOOK THE CAR TO A LOCAL MECHANIC WHERE THE FIXED A SENSOR. THAT WAS AROUND A YEAR AGO. I TRAVEL A LOT FOR MY JOB AND TODAY I ARRIVED IN PORTLAND OREGON HAD PULLED OFF THE INTERSTATE TO GET FUEL, AND ONCE I PULLED OUT TO THE EXTREMELY BUSY INTERSECTION MY CAR DID THIS AGAIN! I WAS STOPPED AT A STOP LIGHT AND ONCE IT TURNED GREEN BOOM CAR DIED DUE TO TRACTION CONTROL. SO NOW I'M IN THE MIDDLE OF A VERY BUSY ROAD WITH TRAFFIC GOING AROUND 45 MPH ALMOST REAR ENDING ME. I TOOK THE KEY OUT OF THE IGNITION FOR ABOUT 45 SECONDS AND TRED STARTING IT WHICH WORKED. FOOLISHLY I THOUGHT I COULD AT LEAST MAKE IT TO THIS...
