2011 CHEVROLET IMPALA Engine Problems

Service stabilitrak warning, followed by reduced engine power, then car starts jerking.

i own a 2011 chevy impala 4 door that has a very serious engine issue. I was on my way home and suddenly the service stability trac, and check engine light came on, then the message center displayed reduced engine power and low oil pressure then the engine shut off. I tried to restart the vehicle and it would not restart. I got it towed to a parking lot where it sat over night then it would restart but only for a few minutes. Once I got a scanner hooked up it had a p0642 code lost 5 volt reference circuit 1 and a cam sensor code I worked on this vehicle for two days and still have not found the issue. this vehicle needs a recall since this is a recurring issue with a few different model years of this vehicle and its always the same issue word for word, check engine light comes on, service stability trac, reduced engine power and low oil pressure lights come on the same p0642 lost 5 volt reference circuit 1. This is a very dangerous situation when going down the road and you lose engine power, steering and braking power. GM needs to correct this issue too many people have had this same issue.

This problem has happened for many many years. Made appointments @ Fuccillo Chevy dealer, by then it’s gone off & they don’t know! Well, just occurred again when getting new tires @Dunn pulling in. 2011 impala Stabilitrak, engine power loss, then check engine light! Thank goodness the mechanic printed me the codes & what they mean!! SO- P2138 Throttle/pedal pod sensor voltage correlation DTC P0523 Engine oil pressure sensor/switch high input Same complaint of loss of power as I’ve now seen others write about!! Voltage referring to throttle ‘s ability to open/close properly. An electrical malfunction in manufacturing! RECALL!!! Obviously I actually have another impala- 2007 that the rear defrost wire’s actually burnt @ control junction, been replaced now. Could’ve caused a fire !! High beam lights come on intermittently when using the turn signals!! Stand by your product !!!! I have 2 Impala’s, 2007, 2011. My mother has Impala, 2015. My sister has an Impala, 2017. Impala family I guess- kinda funny, all are black Impalas!!! I’ve seen numerous complaints of this same issue! Defect! R u waiting 4 an accident or a death? GO !!!! Has happened numerous times b4 This report, Chevy dealer has previously stated can’t anything because the code disappears on its own. What’s with that? Resets itself?? It does!! Sure have had it happen, 20 x’s?? I make an appointment & by that time- gone! Seriously!!! Finally caught it 2 code it !!

Service stabilitrak warning light goes off and on intermittently when this happens the traction control light comes on when hooked up it shows no codes everything I’ve read on line is that it’s a electrical issue to replace wheel bearings or gas pedal or other list of sensors shouldn’t this be something that you should investigate to let owners know what to fix it seems to be a issue on several different models of Chevy autos if forums are correct next step is it will go into limp mode or shut off completely that one would think would be a serious safety issue as you loose power steering as you have to fight to get to shoulder of the highway

Today, 6-12-2022, driving on US Highway 80 at 65 mph headed toward Phenix City, AL from Columbus, GA, the the engine shuddered, then the "Stabilitrack Service Light" came on, along with the check engine light, and a message for "reduced engine power." Then, the engine suddenly cut out as I was going uphill between the Riverchase Exit and the Summerville Exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under ZERO power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the Summerville Exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this Model, the Chevy Impala. I'm sure Chevrolet knows about this...the company should be forced to recall this car model and fix it before folks start getting killed due to total engine failure...especially at a high speed like I was driving.

The car was purchased 06/23/2021. Approx 2 weeks or less later the car had to be taken to the shop where it was purchased at due to the engine going in the car. There have been 3 loaner cars given while car is being fixed however after now 4 months the car is still just sitting at the shop where it was purchased at without the engine being replaced or repaired. There is a loan on this vehicle and it is very unfair that the loan has to continue to be paid for when the car is not in possession of the owner. I do not want the car back at this point because it is now out of warranty and has been sitting for a long time without being fixed. I have called many times and have been getting the run around. Now the owner of the shop or workers will not answer my phone calls. My name is [XXX] my contact information is [XXX]. I am helping my son out because he is and have been getting the runaround since he purchased this vehicle from Ecars.

- SERVICE STABILITRAK. A REDUCED POWER LIGHT USUALLY INDICATES A FAIRLY SERIOUS PROBLEM WITH THE THROTTLE SYSTEM. WHEN THIS LIGHT ILLUMINATES THE VEHICLE WILL OFTEN GO INTO A 'SAFE MODE', WHICH WILL SEVERELY LIMIT THE SPEED OF THE CAR AND IN SOME CASES WILL RENDER THE VEHICLE UN-DRIVABLE.

JANUARY 2019 WAS DRIVING ON A VERY CONGESTED INTERSTATE 95 AT THE POSTED SPEED LIMIT OF 65. A WARNING POPPED UP ON MY DASH BOARD.SERVICE STABIL TRAK ENGINE IN REDUCED POWER. IT WAS LIKE I LONGER CONTROLLED MY CAR. THE SPEED SUDDENLY DROPPED. I WENT FROM 65MPH TO MAYBE 30MPH. IT FELT LIKE MY BRAKES WERE BEING APPLIED . I BECAME SCARED AND ALMOST STARTED TO PANIC. BUT BECAUSE I WAS IN THE FAR RIGHT LANE I WAS ABLE TO PULL OFF THE INTERSTATE. I SAT THERE ON THE SIDE OF THE INTERSTATE WITH MY HEART RACING AND MY HANDS LOCKED ON THE STEERING WHEEL SO HARD THEY CRAMPED UP. I TURNED OFF MY CAR AND REMOVED THE KEYS FROM THE IGNITION. I THANKED GOD I WAS ALONE IN THAT CAR. I THANKED GOD THE CAR BEHIND ME WAS NOT TAILGATING ME. I WAITED FOR ABOUT 5 MINUTES AND THEN PUT THE KEY BACK IN THE IGNITION AND STARTED THE CAR UP. THE WARNING WAS GONE BUT THE SERVICE ENGINE LIGHT REMAINED ON. I WAS SCARED TO DEATH TO MERGE BACK ONTO THE INTERSTATE SO I PUT ON MY FLASHERS AND DROVE ON THE SHOULDER AT 20-30MPH UNTIL I GOT TO THE FIRST EXIT. I MADE IT HOME. I CALLED A CAR REPAIR COMPANY. THEY TOLD ME THE SENSOR MORE THAN LIKELY NEED TO BE RESET. THEY SUGGESTED I TAKE IT TO A CHEVY DEALERSHIP SERVICE CENTER. THE NEXT DAY I STARTED MY CAR UP AND ALL WARNING WERE GONE SO I DID NOT TAKE IT TO THE SERVICE CENTER. THE CAR RAN FINE UNTIL TODAY 52/20/2019. I JUST FILLED MY TANK UP WITH GAS. TURNED IT ON PUT IT IN GEAR AND DROVE 20FEET WHEN THE SAME ERROR CAME ON . I HAD LOOKED UP THIS ERROR ON THE INTERNET. SEEMS LOTS OF AMERICANS HAVE ALMOST BEEN KILLED BECAUSE A CAR MAKER HAS A MECHANISM BUILT IN TO IT VEHICLE THAT TAKES CONTROL OF THE SPEED TO WHICH THE VEHICLE IS TRAVELING. PEOPLE ARE SPENDING A LOT MONEY TO FIX AN ISSUE THAT SEEMS TO NOT HAVE A FIX. CHEVROLET IS PUTTING THE LIVES AND THE LIVES OF OTHERS ON THE ROADS IN JEOPARDY WITH THEIR STABIL TRAK COMPUTER SENSORS.YOUR FAILING AMERICANS

YOU REALLY WANT TO KNOW WHAT I THINK? OK...HERE'S WHAT I THINK. I THINK THAT IS BEYOND COMPREHENSION AND PERSONALLY I THINK IT'S ILLEGAL THAT GM CAN GET AWAY WITH NOT HAVING TO PUT OUT A RECALL FOR THE "ENGINE POWER IS REDUCED" ISSUE THAT JUST ABOUT EVERY MAKE AND MODEL OF GM VEHICLES HAVE. IT'S NOT ONLY TIME CONSUMING TO TRY AND FIGURE OUT WHAT THE FIX WOULD BE BECAUSE IT'S NOT ALWAYS THE SAME THING WRONG ON EACH VEHICLE (AND WHEN YOU DO HAVE IT FIXED IT DOESN'T LAST VERY LONG UNTIL THE "ENGINE POWER IS REDUCED" WARNING COMES BACK), IT'S ALSO VERY EXPENSIVE BUT THE BIGGEST PROBLEM IS THAT IT'S EXTREMELY DANGEROUS. THE POWER IS REDUCED AND ACTUALLY TURNS THE CAR ENGINE OFF NO MATTER IF YOU'RE DRIVING OR NOT. IT SHUT MY 2011 CHEVROLET IMPALA ENGINE OFF AS I WAS DRIVING DOWN THE INTERSTATE. THANK GOD THERE WAS VERY LITTLE TRAFFIC OR IT COULD HAVE BEEN CATASTROPHIC. I DIDN'T REALIZE HOW BIG OF A PROBLEM THIS WAS UNTIL I STARTED RESEARCHING THE PROBLEM. IT'S ABSOLUTELY CRIMINAL THAT YOU PAY YOUR HARD EARNED MONEY FOR A VEHICLE AND IT NOT ONLY ISN'T WHAT YOU THOUGHT YOU WERE PAYING FOR BUT IT CAN ACTUALLY TAKE YOUR LIFE AND RUIN YOUR FAMILY BECAUSE GM'S BOTTOM LINE IS MORE IMPORTANT THAN THEIR CUSTOMERS LIVES. I'VE FILLED A COMPLAINT ON THIS PROBLEM ALREADY AND IF SOMETHING ISN'T DONE AND IT'S THE CAUSE OF GRIEF FOR MY FAMILY I WILL MAKE IT MY MISSION TO MAKE SURE GM NOT ONLY FIXES THEIR CRAPPY WORKMANSHIP BUT THAT THEY ALSO DIG INTO THEIR BOTTOM LINE AND COMPENSATE THEIR CUSTOMERS FOR THE HEARTACHE AND GRIEF THEY HAVE CAUSED. IT'S A PRETTY SIMPLE FIX FOR THEM AND THAT WOULD BE TO ACKNOWLEDGE THE PROBLEM AND JUST FIX IT, BUT I JUST DON'T THINK THEY CARE ENOUGH TO DO THAT. I'VE ALWAYS BEEN A CHEVY GUY, BUT AFTER THIS IMPALA I WILL NEVER OWN OR DRIVE ANOTHER GM PRODUCT FOR AS LONG AS I AM AROUND. THAT'S WHAT I THINK. SIGNED, CHEVY GUY FORCED TO NOT BE A CHEVY GUY

I WAS DRIVING ON I-695 (IN BALTIMORE) WITH MY 3 DAUGHTERS I RECEIVED "SERVICE STABILITRAK, TRACTION CONTROL, ENGINE POWER REDUCED" MESSAGE WHILE DRIVING AROUND 65 MPH. THE ENGINE AND TRACKING LIGHT CAME ON AND THE MESSAGES WOULD NOT GO AWAY. I WAS FRIGHTEN AND HOPEFUL THAT WE WOULD NOT ONLY MAKE IT TO OUR DESTINATION BUT THEN BACK HOME AGAIN. FORTUNATELY WE DID BUT THE VERY NEXT DAY I HAVE RESEARCHED THIS ISSUE. IT SEEMS TO BE A ONGOING ISSUES AND MAYBE COST ME HUNDREDS OF DOLLARS TO REPAIR. THAT MAKES ME NERVOUS BECAUSE I AM A SINGLE MOTHER WITH ONLY ONE SOURCE OF INCOME.

WHY IS THERE NOT A RECALL ON STABILITY TRACTION CONTROL? I SEE THOUSANDS OF COMPLAINTS ON THE INTERNET FOR GM VEHICLES. IT SEEMS TO ME THAT GM JUST DOESN'T CARE ENOUGH AFTER THE SALE. I JUST BOUGHT 2011 IMPALA AND NOW THE STABALITRACK SERVICE LIGHT KEEPS COMING ON WHILE GOING DOWN THE ROAD. IT WILL DO THIS FOR NO APPARENT REASON BUT HAPPENS MOSTLY WHEN ACCELERATING. USING THE CRUISE CONTROL ON LEVEL ROAD AND DASH WARNING LIGHT COMES ON AND THROWS CAR OUT OF CRUISE, DECELERATING WHILE GAGES FLIP AROUND ALL OVER THE PLACE. POWER LOSS AND LACK OF ACCELERATION ARE DEFINITELY SAFETY ISSUES. PULLING OUT OF MY DRIVEWAY ONTO MICHIGAN HIGHWAY AND I GET HALFWAY ACROSS HIGHWAY AND CAR STOPS. THIS HIGHWAY IS 55 MPG AND WHILE I WOULD HAVE HAD PLENTY OF TIME TO CROSS THE LANE, CAR LOOSES ALL POWER. LOOKING ON THE INTERNET GIVES NO HELP FOR A FIX. I TURNED THE STABILITY TRACTION CONTROL OFF, BUT THE PROBLEM DOES NOT GO AWAY. I SEE ON THE INTERNET THAT MANY PEOPLE HAVE TAKEN THERE VEHICLE TO THE DEALER GARAGE ONLY TO GET CHARGED EXORBITANT PRICES FOR "POSSIBLE" THAT DO NOT SEEM TO HELP. GM SHOULD GET THIS FIGURED OUT AND NOT LET EVERY DEALER GARAGE DO THEIR OWN GUESSING ON WHAT WILL FIX THIS VERY DANGEROUS PROBLEM THAT IS NOT LIMITED TO SINGLE MODEL OR YEAR BUT SPANS MANY YEARS WITH MANY MODELS. MY FIRST VEHICLE WAS A GM BUT THIS MAY BE MY LAST GM. I WOULD LIKE TO GIVE A DATE BELOW BUT THIS HAS BEEN HAPPENING SINCE I BOUGHT THE VEHICLE ABOUT A MONTH AGO AND GETTING STEADILY WORSE. I HAVE HAD IT CHECKED OUT BUT NOBODY CAN GIVE ME ANY USEFUL ANSWERS

ON TWO DIFFERENT OCCASIONS, ONCE ABOUT A YEAR AGO AND AGAIN TODAY, MY 2011 CHEV IMPALA LTZ DISPLAYED A SERIES OF ROTATING ALERT MESSAGES -- 1. SERVICE TRACTION CONTROL 2. SERVICE STABILITRAK 3. ENGINE POWER IS REDUCED. I WAS DRIVING ABOUT 45 MILES PER HOUR ON AN OPEN ROAD WHEN ALL OF A SUDDEN THE ENGINE STARTED RUNNING VERY ROUGHLY AND SLOWED DOWN AND THE ABOVE 3 MESSAGES REPEATEDLY DISPLAYED ONE AFTER THE OTHER. ALSO 2 YELLOW LIGHTS WERE FLASHING AND THEN REMAINED ON -- THE CHECK ENGINE LIGHT AND THE TRACTION CONTROL LIGHT (I THINK). WHEN I REPORTED THIS PROBLEM TO THE CHEV DEALERSHIP A YEAR AGO, I WAS TOLD THAT BECAUSE THE WARNING LIGHTS AND MESSAGES COULD NOT BE REPRODUCED IN THE SERVICE DEPARTMENT, THERE WAS NOTHING THAT THEY COULD DO. (AND I UNDERSTAND THAT IF IT ISN'T BROKEN WHEN I TAKE IT IN, THE SERVICE DEPT WOULD MOST CHALLENGED TO FIX IT.) TODAY, WHEN THIS HAPPENED I WAS ABLE TO GET THE CAR TO A SAFE PLACE TO PARK. I TURNED OFF THE IGNITION, WAITED A MOMENT AND THEN RESTARTED THE CAR. THE SAME 3 MESSAGES WERE DISPLAYED WITH THE TWO YELLOW LIGHTS STAYING ON. WHEN I RESTARTED THE CAR 3 OR 4 HOURS LATER, ONLY THE CHECK ENGINE LIGHT IS DISPLAYED. THE 3 REFERENCED ALERTS WERE NOT DISPLAYED. I AM GETTING READY TO TAKE THE CAR TO THE DEALERSHIP AGAIN WITH THIS PROBLEM. DO YOU HAVE ANY ADVICE AS TO HOW TO PROCEED?

THEN MY VEHICLE STARTED TO JERKILY MOVE & THEN IT ALERTED "STARTER DISABLED SERVICE THROTTLE" AND MY CAR SHUT DOWN (STEERING ALTERED & CAR SHUT OFF). I WAS ABLE TO MANEUVER TO THE SIDE OF THE ROAD & TRIED TO RESTART MY CAR (UNSUCCESSFULLY FOR APPROXIMATELY 10 MINUTES). DID I MENTION I HAD MY 2 CHILDREN IN THE CAR WITH ME WHEN THIS HAPPENED? THIS WAS TERRIFYING AS MY CAR JUST STOPPED-I HAD MINIMAL WARNING & WHEN TRAVELING ON THE INTERSTATE IT COULD'VE BEEN A LOT WORSE.

I COULDN'T STOP AT THE LIGHT AT THE END OF THE EXIT, LUCKILY NO OTHER CARS WERE AROUND. IF I HAD BEEN ON A MAIN STREET AT 45MPR AND HAD TO STOP FOR A RED LIGHT I WOULD HAVE NEVER STOPPED ON TIME. I'M VERY LUCKY NO CARS WERE AT THE LIGHT WAITING OR COMING IN A DIFFERENT DIRECTION WITH THE GREEN LIGHT. I SEE THIS PROBLEM ALL OVER EDMUNDS AND ON YOU TUBE AND AS FAR AS I CAN TELL IT'S 100% CHEVROLET. HOW CAN THIS NOT BE A RECALL. THERE ARE DOZENS AND DOZENS OF THE SAME COMPLAINT ON EDMUNDS AND YOU TUBE. IT SEEMS LIKE EVERY YOU TUBE VIDEO HAS A DIFFERENT FIX FOR THE PROBLEM....FROM PULLING OUT THE FUSE TO THE STABILITRACK TO OVER A THOUSAND DOLLARS IN REPAIRS. DOES THERE HAVE TO BE A DEATH TO GET THE ATTENTION OF CHEVROLET. THE LIGHT HAD COME ON A FEW TIMES BEFORE BUT THIS WAS THE FIRST TIME IT HAPPENED WHILE I WAS DRIVING. USUALLY IT CAME ON AND I WOULD TURN THE CAR OFF FOR A FEW MINUTES AND IT WOULD BE FINE......SO HOW COULD THIS BE ANYTHING BUT A MALFUNCTION IF IT GOES OFF AND ON AT ANY WHIM. THEY MUST KNOW ABOUT THIS PROBLEM AS IT SEEMS TO BE VERY PREVALENT AND AGAIN FROM WHAT I HAVE READ IT'S ALWAYS A CHEVROLET.

MY CAR JUST REACHED 79,000 MILES AND I WAS DRIVING WHEN MY CAR CUT OFF IN THE MIDDLE OF TRAFFIC! THIS HAPPENED TWICE IN THE SAME DRIVE. IT IMMEDIATELY STARTED BACK UP BUT THEN THE CHECK ENGINE LIGHT CAME ON ALONG WITH A STABILITRAK ERROR MESSAGE. THEN A MESSAGE SAYING ENGINE POWER IS REDUCED. NOW THE CAR'S ENGINE IS MAKING A TERRIBLE NOISE AND IS HAVING PROBLEMS ACCELERATING WITHOUT MAKING A LOUD SOUND LIKE AIR TRYING TO BLOW THROUGH A PINHOLE. THE CHEVY SERVICE DEPARTMENT I TOOK IT TO WANTS ALMOST $700 JUST TO TAKE IT APART TO SEE WHAT IT WRONG WITH IT, WHICH DOESN'T INCLUDE THE POSSIBLE AMOUNT FOR REPAIR. AND THEY DID NOT LOOK AT ANY OF THE TECHNICAL SERVICE BULLETINS LIKE REQUESTED! NOW THEY ARE SAYING MY CAR IS NOT ABLE TO BE DRIVEN AT ALL. I WENT ONLINE AND STARTED TO RESEARCH THESE ISSUES AND FOUND THAT THERE HAS BEEN A LOT OF COMPLAINTS ABOUT THESE EXACT ISSUES MOST EVEN THE SAME YEAR. THERE IS NO REASON THAT A CAR WITH 79000 MILES SHOULD HAVE ENGINE PROBLEMS. I OWNED A 2003 IMPALA PRIOR TO THIS ONE AND HAD ALMOST 125000 MILES BEFORE I PURCHASED THIS 2011. THERE ARE WAY TOO MANY COMPLAINTS GOING ON WITH THIS CAR FOR IT NOT TO BE RECALLED.

Mileage: 79,500

WHILE DRIVING DOWN THE HIGHWAY, MY CAR SHUT DOWN. THIS WAS VERY DANGEROUS. I PULLED OVER ON THE SHOULDER AND EVERY LIGHT WAS ON STATING ENGINE POWER REDUCING. I HAVE HAD THIS SAME PART REPLACED TWICE IN 1.5 YEARS AND THERE IS SOMETHING SERIOUS WRONG WITH THE IMPALA.

Mileage: 109,000

G.M. REPLACED MY INGINTION SWITCH ON A NATIONAL RECALL. I WAS HIT IN LEFT REAR QTR. PANEL. I LOST ALL POWER AND COULD NOT STOP OR STEER THE CAR. I CAREENED ACROSS HIGHWAY AND RAN INTO A HOUSE. NO AIR BAGS DEPLOYED EITHER. G.M. SENT A TEAM TO RECOVER COMPUTER INFO AND HAS NOW TOLD ME THERE IS NO PROBLEM.

GOT A MESSAGE ON MY DASH A FEW MONTHS AGO ABOUT "SERVICE TRACTION CONTROL" WHILE DRIVING. TRACTION CONTROL LIGHT LIT UP ALSO. PARKED CAR AND TURNED CAR OFF THEN ON...MESSAGE GONE. TOOK IT INTO SERVICE...SHOWED NO ERROR CODES. TODAY (5/2/16), IT DID IT AGAIN WITH THE TRACTION CONTROL LIGHT AND THE CHECK ENGINE LIGHT SIMULTANEOUSLY LIGHTING UP. "SERVICE STABILITRAK", SERVICE TRACTION CONTROL", AND "ENGINE POWER IS RECUDED" ARE THE MESSAGES I GOT TODAY ALONG WITH THE CHECK ENGINE LIGHT AND THE TRACTION CONTROL LIGHT BEING ON. I HAD JUST GOTTEN OFF THE HIGHWAY SO I WASN'T GOING FAST WHEN THIS HAPPENED. I WAS CLOSE TO WORK SO I PARKED IT AT WORK. TURNED THE CAR OFF THEN ON AGAIN AND THE MESSAGES WERE GONE AND TRACTION CONTROL LIGHT WAS OFF BUT CHECK ENGINE LIGHT STAYED ON. TURNED CAR ON AGAIN AT LUNCH 1.5 HOURS LATER AND THE CHECK ENGINE LIGHT IS OFF NOW SO I DOUBT ANYONE WILL BE ABLE TO DIAGNOSE OR FIX ANYTHING TODAY. TAKING IT TO SERVICE TO SEE IF IT THREW ANY ERROR CODES A LITTLE LATER TODAY. I'VE RESEARCHED THIS ISSUE AND FOUND THAT THIS HAS HAPPENED TO A LOT OF PEOPLE WHILE ON THE HIGHWAY. IF IT HAPPENS TO ME AND I'M IN AN ACCIDENT BECAUSE OF THIS, I WILL SUE THE S**T OUT OF GM. I HAVE TWO SMALL CHILDREN AND IF ANY OF US GETS HURT OR KILLED, THERE WILL BE H**L TO PAY. THIS ISSUE SHOULD ABSOLUTELY BE RECALLED. IT IS NOT DUE TO MY KEY/IGNITION ISSUE. ALREADY HANDLED THAT RECALL. LOSING POWER IN THE MIDDLE OF THE HIGHWAY RANDOMLY IS ABSOLUTELY DANGEROUS AND I'M NOW VERY AFRAID TO DRIVE THIS VEHICLE. WILL NEVER BUY ANOTHER IMPALA AGAIN.

WHILE DRIVING THE TRACTION CONTROL,STABILIZER,ENGINE POWER WARNING ALL COME ON AND THE CHECK ENGINE LIGHT COMES ON AND SOMETIMES THE ENGINE TURNS OFF. PULL OFF ROAD, WILL NOT START THEN MINUTES LATER IT STARTS. CHECK ENGINE LIGHT STAYS ON. AFTER MULTIPLE STARTS THE CHECK ENGINE LIGHT GOES OUT . I HAVE READ MULTIPLE COMPLAINTS ABOUT THIS ,YET THE NOTHING IS BEING DONE. TO REPAIR THIS PROBLEM. THE EFFECTS OF THIS IS THE SAME AS THE IGNITION TURNING OFF. PENDING ON TRAFFIC.

I BEGIN NOTICING ISSUES WHEN TAKING OFF FROM A COMPLETE STOP WHERE THE VEHICLE WOULD LUNGE FORWARD LIKE IT COULDN'T SHIFT INTO FIRST GEAR. I HAD THAT CHECKED AND NOTHING SHOWED AS AN ISSUE, SO THE MECHANIC SAID IT HAD TO BE ELECTRICAL. THIS WEEKEND I AM DRIVING IT AND AFTER 25 MINUTES IN THE CAR THE CHECK ENGINE LIGHT COMES ON, AS DOES THE NOTICE THAT MY ENGINE POWER HAS BEEN REDUCED, AND TO SERVICE THE STABILITY TRACTION CONTROL SYSTEM. I WAS COMING TO A STOP LIGHT WHEN IT CAME ON AND I PULLED OFF TO TURN OFF THE CAR AND RESTART IT AS THAT WOULD WORK WHEN IT FAILED BEFORE TO RESET THE SYSTEM. IT DIDN'T RESET AND I HAD TO DRIVE IT WITH REDUCED POWER THE REST OF THE WAY TO MY DESTINATION. I HAD THIS FIXED A COUPLE YEARS AGO. I DID GET A NOTICE FROM GM ABOUT THE ISSUE AND THE ABILITY TO BE REIMBURSED OR GETTING IT FIXED IF THERE WAS A CURRENT ISSUE AND I WAS ABLE TO GET REIMBURSED FOR IT. NOW IT IS HAPPENING AGAIN, BUT MY MILEAGE IS TOO HIGH TO GET IT FIXED UNDER THIS REPAIR NOTICE BECAUSE THE LETTER SAYS THAT THE MILEAGE COVERAGE IS ONLY UP TO 120,000. IF THIS IS A KNOWN ISSUE AND I HAVE ALREADY DEALT WITH IT BEFORE, WHY SHOULD I HAVE TO PAY FOR IT TO CONTINUALLY FAIL WHEN IT HAS NOTHING TO DO WITH NORMAL WEAR AND TEAR, WHICH I WOULD HAVE NO ISSUE FIXING AS A PART OF MAINTAINING THE VEHICLE?! THIS SHOULD BE SOMETHING THAT GM WOULD FIX EVERY TIME IT GOES OUT BECAUSE IT IS CLEAR THE ISSUE IS A MALFUNCTION OF THE OVERALL SYSTEM AND NOT LINKED TO ANYTHING THAT THE DRIVER DOES OR DOESN'T DO TO MAINTAIN THE VEHICLE PROPERLY. IN ADDITION WHAT IF IT HAS TO BE REPLACED MULTIPLE TIMES AS IS THE CASE WITH MINE. I HAVE ALWAYS BEEN A DEVOTED GM CUSTOMER, BUT HONESTLY I AM NOT SURE I WILL EVER BUY ANOTHER GM AFTER THIS ISSUE. IT IS UNSAFE AND PROVIDES ANXIETY WHEN DRIVING, BECAUSE IT MIGHT FAIL AT THE WORST TIME AND COULD NEED FIXED AGAIN EVEN IF I FIX IT THIS TIME.

Mileage: 138,000

SERVICE TRACTION CONTROL AND CHECK ENGINE LIGHTS CAME ON THIS MORNING. THEN A MESSAGE SAYING MY ENGINE POWER IS REDUCING. I JUST BOUGHT THIS CAR 3 WEEKS AGO.

I HAVE PROBLEM WITH THE STABILITRAK/TRACTION CONTROL ON A 2011 IMPALA WITH 120,000 MILES. I HAVE FOUND OTHER PEOPLE FROM ALL OVER THE COUNTRY WITH THE SAME PROBLEM. I HAVE TAKEN IT TO 3 DIFFERENT MECHANICS AND THEY ARE ALL UNSURE AS TO WHAT IT IS. I HAVE PUT A NEW THROTTLE BODY IN, NEW SPARK PLUGS, CHANGE MY OIL FAITHFULLY EVERY 3,000 MILES. IT CONTINUES TO FLASH THE MESSAGE TO ME, DOES NOT HAVE THE SAME ACCELERATION, IS VERY UNPREDICTABLE AS FAR AS REDUCING MY ENGINE POWER AT ANY GIVEN TIME. THIS HAPPENS WHEN I'M DRIVING DOWN THE ROAD AND EVEN WHEN I JUST START MY CAR. I HAVE TO TURN CAR OFF, LET IT SIT FOR A FEW MINUTES AND THEN IT SEEMS TO RESET BUT THE ENGINE LIGHT STAYS ON FOR A FEW DAYS. THIS NEEDS TO BE ADDRESSED WITH AS MANY COMPLAINTS I AM READING ABOUT!

WE OWN BOTH A 2011 AND A 2013 CHEVY IMPALA. BOTH VEHICLES GRIND AND HESITATE. THEY BOTH ACT THIS WAY WHILE TAKING OFF FROM A LIGHT, BACKING OUT OF THE DRIVEWAY AND THEN PUTTING IT IN DRIVE AND ANY OTHER TIME IT FEELS NECESSARY TO DO SO. EXCEPT WHILE BEING CHECKED BY THE MECHANIC. WE OWNED A 2007 IMPALA THAT DID THE SAME THING. OUR REMEDY, PUSH THE TRACTION CONTROL BUTTON TO THE "OFF" POSITION. STOPPED MAKING THE NOISE AND NO LONGER HESITATES AFTER PUTTING IT IN DRIVE. OF COURSE, WE HAVE TO DO THIS EACH AND EVERY TIME WE GET IN THE CAR. NO MORE BUYING CHEVY'S FOR US.

WHEN THE ACCELERATOR PEDAL IS RELEASED, THE CAR DOES NOT SLOW DOWN. DEALER SAYS CAR IS OK. THIS HAPPENS AT ANY SPEED AND MAKES IT DIFFICULT TO SLOW DOWN OR STOP.

WHILE DRIVING ON THE HIGHWAY THE "SERVICE TRACTION CONTROL" MESSAGE COMES ON, THEN, THE MESSAGES "SERVICE STABILITY TRAK" THEN "ENGINE POWER IS REDUCED". AND THEN THE CAR SHUTS DOWN I HAD TO QUICKLY PULL OVER ON THE SIDE OF THE ROAD. AFTER A FEW MINUTES THE CAR STARTS UP AND EVERYTHING IS FINE. THIS HAPPENED TWICE SINCE THEN. EVERY COUPLE MONTHS THE SENSOR LIGHTS WOULD COME ON WITH THE ABOVE MESSAGE-WITHOUT CAR SHUTTING DOWN. THE LIGHTS COME ON A LOT MORE OFTEN NOW-ALTHOUGH THE CAR DOES NOT SHUT DOWN, IT'S THE FEAR OF THE POSSIBILITY. WHEN GOOGLING THIS PROBLEM WITH THE CAR IT SOUNDS LIKE THIS IS A COMMON PROBLEM. I'M NOT SURE WHY THERE HASN'T BEEN A RECALL. I'M BRINGING IN MY CAR TOMORROW TO GET FIXED. HOWEVER, ITS UPSETTING THAT THERE SEEMS TO BE A PROBLEM WITH THE THROTTLE POSITION SENSOR, AND THERE WAS A RECALL ON A GMC TRUCK IN 2008 FOR THIS PROBLEM. THIS SEEMS TO BE A PROBLEM REGARDLESS OF YEAR OF MILES OF THE IMPALA. *TR

I WAS DRIVING ON A HIGHWAY GOING APPROXIMATELY 55 MPH, THE ENGINE LIGHT, STABILITY CONTROL LIGHT, AND REDUCED ENGINE POWER LIGHT CAME ON AT THE SAME TIME. WITHIN TWO (2) MINUTES OF THE DASH WARNING LIGHTS COMING ON, THE CAR COMPLETELY SHUT IT SELF OFF WHILE I WAS DRIVING IN THE LEFT LANE GOING 55 MPH. I LOST STEERING, HAD NO POWER, OR BRAKING. I THREW THE CAR IN NEUTRAL, IN AN ATTEMPT TO GET IT STARTED IT WHILE I WAS IN MOTION WITH NO POWER. THE IMPALA DIDN'T EVEN TRY TO TURN OVER. THE CAR WASN'T RESPONDING BECAUSE THE POWER STEERING / BRAKING WAS NOT RESPONDING. THE IMPALA WENT INTO "LIMP MODE" WITHOUT WARNING. I LET THE CAR COST FOR A WHILE UNTIL I COULD FIND A SAFE SPOT TO APPLY THE EMERGENCY BRAKE. I REALLY HAD TO MUSCLE THE STEERING WHEEL WITH SOME SIGNIFICANT FORCE TO GET IT TO TURN. I HAVE NEVER HAD ANY PROBLEMS WITH THIS VEHICLE BEFORE THIS ISSUE. IT TURNS OUT THAT THE "PEDALASSEMBLY" GAS PEDAL SENSOR WENT BAD, CAUSING THE 2011 IMPALA TO GO INTO "LIMP MODE" WHILE I WAS DRIVING. *TR

I HAVE HAD THIS CAR 6 MONTHS AND IT ONLY HAS 42426 MILES ON IT AND NOW I'VE HAD TO SPEND OVER $300 ON A REPAIR. IT IS RIDICULOUS THAT THIS SENSOR FAILED ALREADY. AFTER DOING SOME RESEARCH, I FOUND THAT THIS IS A COMMON PROBLEM WITH MANY PEOPLE EXPERIENCING THE SAME THING. GM SHOULD BE FORCED TO FIX THIS ISSUE AND REIMBURSE ALL OF US WHO HAVE HAD TO PAY TO FIX THEIR MISTAKE. THEY ARE OBVIOUSLY USING INFERIOR PARTS AND THEIR CONSUMERS ARE PAYING THE PRICE. IT'S NO WONDER THE AMERICAN CAR MARKET NEEDED A BAILOUT WHEN THEIR PARTS DON'T LAST 40,000 MILES. *JS

IN MAY OF 2013 I RECEIVED A MESSAGE ON MY DASH BOARD ABOUT STABILI TRACK, TRACTION CONTROL AND REDUCED ENGINE SPEED. I TOOK MY CAR TO THE CHEVY DEALER SO I COULD GET A DIAGNOSTIC, AND THEY REPLACED A SENSOR BEHIND MY PEDAL. JUST THIS WEEKEND, SUNDAY APRIL 13, 2014. THE MESSAGE DISPLAYED ACROSS THE DASHBOARD AGAIN. I'M GOING TO CALL THE CHEVY DEALER THAT FIXED IT THE FIRST TIME. THEN I'M GOING TO CALL GM. THIS IS A VERY DANGEROUS MALFUNCTION IN THESE CARS. FROM VIEWING AND READING OTHER STORIES, THIS IS SOMETHING GM SHOULD HAVE KNOWN ABOUT AND ADDRESSED. *JS

I WAS DRIVING DOWN THE HIGHWAY ON THE HOMESTRETCH OF A ROADTRIP FROM PA TO FL WHEN THE "SERVICE STABILITRAK" , FOLLOWED BY "ENGINE POWER REDUCED" MESSAGE STARTED FLASHING. THE TWO LIGHTS ON THE DASHBOARD ALSO WENT OFF. SINCE I WAS IN THE MIDDLE OF THE HIGHWAY, I WAS UNABLE TO FIND A GOOD PLACE TO ADDRESS THE ISSUE, AND I FIGURED LIKE MOST TIMES THE "CHECK ENGINE" LIGHT GOES ON, THAT IT WAS SOMETHING THAT I COULD WAIT TO DEAL WITH WHEN I GOT HOME. I CONTINUED DRIVING FOR ABOUT 15 MINUTES AND THEN THE MESSAGE CHANGED AND SAID "DISABLING THROTTLE" OR SOMETHING TO THAT EFFECT, AND I FELT THE ENGINE LOSING POWER. I WAS IN THE MIDDLE LANE, DOING AROUND 55 MILES PER HOUR WITH CARS ALL AROUND ME. I IMMEDIATELY PUT ON MY FOUR-WAY FLASHERS AND FORTUNATELY PEOPLE IN THE RIGHT LANE SLOWED DOWN AND LET ME COAST TO THE SHOULDER BUT IT COULD HAVE BEEN DISASTROUS. I SAT THERE FOR A FEW MINUTES TRYING TO FIGURE OUT WHAT TO DO. FINALLY AFTER A FEW MINUTES I DECIDED TO TRY STARTING THE CAR AGAIN AND IT STARTED, WITH JUST THE CHECK ENGINE LIGHT ON AND I WAS ABLE TO CONTINUE ON MY WAY. SINCE THEN IT HAS CONTINUED TO OCCUR INTERMITTENTLY. I TOOK IT TO THE DEALER, BUT THEY TOLD ME IT WAS A SENSOR IN THE GAS PEDAL BUT THAT IT WAS NOT UNDER WARRANTY. *TR

JULY 2013 HAD HUB BEARINGS REPLACED IN ORDER FOR CAR TO PASS INSPECTION. ISSUE WITH "SERVICE TRACTION CONTROL" HAD NEVER OCCURRED THE PRIOR WINTERS -- CAR SLOWS DOWN, ENGINE SLOWS DOWN -- THIS JUST STARTED HAPPENING AFTER THE HUB BEARINGS WERE REPLACED. ON MARCH 23, 2014, AFTER PAYING TOLLS ON THE TURNPIKE, THE "SERVICE TRACTION CONTROL" WARNING AGAIN APPEARED (NO SNOW, NOTHING TO TRIGGER THE WARNING) AND THEN MY CAR STOPPED, NO POWER...THE STEERING LOCKED...FORTUNATELY I WAS GOING SLOW ENOUGH AND SOMEHOW MADE IT TO THE BREAKDOWN LANE. CAR HAD ABSOLUTELY NO POWER...COMPLETELY DEAD. WAITED ABOUT 1/2 HOUR AND WAS ABLE TO RESTART. CALLED GM 3/25 WHO CONTACTED THE DEALER FOR AN APPOINTMENT FOR ME. DEALER NEVER CALLED ME (NOW 4/7/14). I HAVE PLACED ANOTHER CALL TO GM. THE VEHICLE SHOULD NOT COMPLETELY SHUT DOWN. ASKED GM IF THERE WAS A RECALL AND WAS TOLD NO. I HOPE OTHERS WHO EXPERIENCE THIS WILL FILE COMPLAINTS SO THAT THEY WILL RECALL. HAD I BEEN IN A DIFFERENT LANE, I MAY HAVE HAD SOMEONE CRASH INTO ME AT 65 MPH AND I PROBABLY WOULD NOT BE ALIVE. THIS NEEDS TO BE RECALLED. TOO DANGEROUS. *TR

I WAS DRIVING ON HWY 41 N IN SOUTH GEORGIA AND MY ENGINE LIGHT COMES ON AND 3 MESSAGES COME UP: 1) SERVICE STABILTRAC, 2) SERVICE TRACTION CONTROL, 3( ENGINE POWER REDUCING (AND IT DID). THEN THE CAR SEEMS TO WANT TO STOP OR HESITATE LIKE ITS RUNNING OUT OF GAS (STILL HAVE HALF TANK). I BECOME AFRAID I PULL OVER AND PUT CAR IN PARK AND IT'S LIKE THE CAR WANTS TO SHUT OFF BUT IT DOESN'T UNTIL I SHUT THE ENGINE DOWN (WHEN I SLOWED DOWN THE CAR STARTED SHAKING). I BOUGHT THIS CAR LESS THAN SIX MONTHS BACK AND IT HAD ONLY 46,000 MILES ON IT. NOW I HERE SOME RATTLING COMING FROM SOME WHERE AROUND THE WHEEL. I HAVE READ MANY OTHER COMPLAINTS ALMOST IDENTICAL TO MINE. TODAY 4/2/2014 THE ENGINE LIGHT IS ON BUT I DON'T SEE ANY OF THE WARNINGS AND THE CAR HAS NOT HESITATED AS BADLY AS IT DID YESTERDAY. BUT FROM WHAT I HAVE RESEARCHED ON THIS MATTER GM NEEDS TO ISSUE A RECALL AND ADDRESS THIS MATTER AS IT COULD CAUSE BE THE MAKING OF SOME SERIOUS LAW SUITS. *TR

I HAVE BEEN HAVING MAJOR ISSUES OUT OF THIS CAR FIRST IT WAS THE RIGHT HUB (EATING TIRES), THEN THE LEFT HUB (EATING MORE TIRES), THEN THE TRANSMISSION AND GEAR SHIFT COMPLETELY GONE (REPLACED EVERYTHING) NOW THIS PLUS THE FRONT TIRES ARE STILL GETTING ATE UP. THIS IS AN ONGOING PROBLEM WITH THIS CHEVY IMPALA. I AM SO READY TO GET A HONDA. AS I SEE THERE ARE OTHER OWNERS THAT ARE HAVING SIMILAR PROBLEMS. WHY ISN'T IT A RECALL ON THESE PROBLEMS?

I WAS DRIVING ON I70 GOING 70 MPH AND OUT OF NOWHERE MY ENGINE LIGHT COMES ON AND 3 MESSAGES START APPEARING ON THE DASH. 1) SERVICE STABILTRAC, 2) SERVICE TRACTION CONTROL, 3( ENGINE POWER REDUCING. MY CAR A 2011 CHEVY IMPALA SLOWS DOWN TO ABOUT 50. I GET IT GOING BACK TO 60 BUT NOT VERY EASILY. I KEEP GOING AND MERGE ONTO 465 (INDIANAPOLIS INDIANA AREA). I COME INTO SLOWER TRAFFIC WHERE I NEED TO STOP. I APPLY MY BREAKS AND THE PEDAL WILL NOT ENGAGE. ALMOST HIT A CAR. ALSO WHEN I SLOWED DOWN THE CAR STARTED SHAKING BAD. I CONTINUE A LITTLE FARTHER IN SLOW TRAFFIC AND HAD TO STOP AGAIN, SAME THING WITH THE BREAKS. SO I PULLED OVER AND SHUT OFF MY CAR ON THE SIDE OF I465. MY DAUGHTER HAD LOOKED UP THE ERROR MESSAGES ON THE INTERNET AND THERE SEEM TO BE A LOT ON THERE WITH THE SAME PROBLEM. THEY ALL SAID THE SAME THING, AFTER SHUTTING THE CAR OFF AND RESTARTING IT IT WAS FINE. I MADE IT HOME AND EVERYTHING SEEMED FINE FOR A COUPLE OF WEEKS AND IT HAPPENED A FEW MORE TIMES SO FAR. ONCE AT A STOP SIGN AND THE SAME DAY AS I WAS BACKING OUT OF PARKING SPACE AT WORK. ONCE AGAIN THAT SAME WEEK I WAS DRIVING IN TOWN AND TOOK OFF FROM A RED LIGHT AND IT HAPPENED AGAIN. FROM A COMPLETE STOP THE CAR STARTED SHAKING AND THE ERROR MESSAGES AND ENGINE LIGHT COME ON AND IT WOULD NOT ACCELERATE. I WOULD HAVE THOUGHT NOTHING ABOUT IT EXCEPT TO GET IT FIXED, BUT AFTER READING SO MUCH ON THE INTERNET ABOUT THE SAME PROBLEM THERE HAS TO BE AN ISSUE AND NEEDS TO BE RECALLED.

THE CAR HAD AN EXTREMELY ROUGH IDLE AND THEN WOULD NOT ACCELERATE TO MORE THAN 25 MPH. I RETURNED HOME AND MADE AN APPOINTMENT AT THE DEALERSHIP. LATER, I WAS READY TO TAKE THE CAR INTO THE DEALER AND IT STARTED FINE WITH NO ERROR MESSAGES OR CHECK ENGINE LIGHT. I CALLED THE DEALER AND THEY SAID IT MUST HAVE BEEN A COMPUTER ERROR THAT FIXED ITSELF. WELL, IT'S A WEEK LATER NOW AND I AM HAVING THE ISSUES AGAIN EXCEPT RESTARTING THE ENGINE DOES NOT FIX IT ANYMORE.

TODAY, ON 11/24/13, WE WERE DRIVING 15 MPH IN A PARKING LOT AND RECEIVED THE SAME MESSAGE RESULTING IN THE SAME PROBLEM. THIS IS A SAFETY ISSUE DUE TO THE FACT THAT THE VEHICLE ESSENTIALLY STALLS OUT WITH LITTLE TO NO POWER AND NEARLY CAUSED A COLLISION AT AN INTERSECTION.

I CALLED GM'S CORPORATE OFFICE (REFERENCE#: [XXX]) AND WAS TOLD THAT MY POWERTRAIN WARRANTY IS STILL GOOD BUT MY BUMPERTOBUMPER WARRANTY HAS EXPIRED DUE TO THE MILEAGE. I ADVISED THE REPRESENTATIVE ([XXX]) THAT I HAD GOOGLED THIS INFORMATION TO FIND OUT WHAT WAS GOING ON AND THIS APPEARS TO BE A KNOWN ISSUE WITH CHEVY IMPLALA'S, AND I ASKED WHY HASN'T GM PUT OUT A RECALL ON THIS ISSUE. SHE THEN TELLS ME THAT I NEED TO PAY AND GET A DIAGNOSTIC CHECK TO DETERMINE THE ACTUAL ISSUE. MY QUESTION TO HER IS "WHY SHOULD I OR ANY CUSTOMER HAVE TO PAY FOR SOMETHING THAT IS A REPORTED KNOWN ISSUE?"

I WAS DRIVING ON THE HIGHWAY AT 60 MPH WHEN MY CAR BEGAN TO SLOW DOWN UNTIL IT CAME TO A STOP. I COULD DO NOTHING BUT SIT THERE I DID NOT HAVE ENOUGH TIME TO MAKE IT TO THE EMERGENCY LANE. I COULD HAVE BEEN KILLED! THE CAR GAVE NO WARNING. I RECEIVED SEVERAL MESSAGES ON THE DASH THAT STATED DISABLED STARTER, SERVICE THROTTLE, AND THE CHECK OIL LIGHT WAS ON. OVER THE TWO YEARS THAT I HAVE HAD THIS VEHICLE I HAVE HAD TO HAVE THE TRANSMISSION REPLACED AND ONE YEAR LATER ANOTHER POTENTIAL COSTLY REPAIR.

WAS ABLE TO PULL OVER AND TAKE A LOOK... TRANSMISSION FLUID WAS FINE... NOTHING POPPED UP ON THE DASHBOARD. NOTHING! THE INDICATORS FOR TIRES, OIL, ETC WERE SHOWING INFO, BUT NOTHING TO INDICATE IT HAD DIED OR IF THERE WERE ANY ENGINE ISSUES. HAD BROUGHT IT TO THE DEALERSHIP WHERE I HAD BOUGHT THE CAR 11 MONTHS AGO. THE MECHANICS WERE SAYING THAT THEY HAVE NEVER SEEN SUCH AN HUGE TRANSMISSION FAILURE BEFORE.

USUALLY I CAN SHUT THE CAR OFF AND WAIT 5 MINUTES, AND THE MESSAGES WILL CLEAR, BUT THE CHECK ENGINE LIGHT WILL REMAIN ILLUMINATED FOR THE NEXT COUPLE OF DAYS, EVENTUALLY CLEARING.
