THE TRANSMISSION WILL FREQUENTLY FAIL TO ENGAGE WHEN STARTING FROM A FULL OR PARTIAL STOP. TURNING LEFT ACROSS TRAFFIC IS EXTREMELY DANGEROUS, AS YOU NEVER KNOW WHEN THE TRANSMISSION WILL FAIL TO ENGAGE. THIS HAS BEEN A ONGOING PROBLEM WITH THIS VEHICLE SINCE THE CAR HAD 38000 MILES ON IT. THIS IS OUR THIRD IMPALA THAT HAS HAD THIS PROBLEM. THE FIRST IMPALA THAT HAD THIS PROBLEM, THE CHEVROLET DEALER COULD NOT DIAGNOSE. THE TRANSMISSION PRESSURE SOLENOID WAS REPLACED BY A LOCAL TRANSMISSION SHOP. THIS FIXED THE PROBLEM FOR THAT CAR. WE ALSO HAVE A 2008 IMPALA THAT HAS THE SAME PROBLEM. THREE IMPALAS, THE SAME TRANSMISSION PROBLEM IN ALL THREE. THE PART NEEDS TO BE RECALLED. WE HAVE DELAYED HAVING THE PART REPAIRED BECAUSE IT IS QUITE COSTLY AND WE HAD HOPED THAT CHEVROLET WOULD DO THE RIGHT THING AND RECALL THE PART ON THEIR OWN.

CHECK DRIVER SIDE AIR BAG LIGHT. DEALER INSPECTION RESULTED IN "BAD SENSOR". WANTED $400. TO REPLACE. CURRENT ISSUE: AWAY FROM HOME. CAR STARTED BUT ENGINE VERY ROUGH. CHECK ENGINE LIGHT, MESSAGE "LOSS OF POWER", CHECK STABIL-TRACK". CAR WOULD SHIFT INTO DRIVE AFTER REVVING UP TO 3K RPM. MAX SPEED ATTAINABLE 55 MPH. MADE IT HOME. NOW UNABLE TO START CAR. (NEW BATTERY) OTHERS WITH SIMILAR PROBLEMS HAD TO REPLACE/CLEAN THROTTLE CONTROL SENSOR?? SOME WERE AT HIGHER SPEED WHEN THE LOSS OF POWER OCCURRED. NO START IS ANOTHER ISSUE?

AFTER STARTING THE MY CHEVY IMPALA THE ENGINE STARTED SHAKING RAPIDLY. IT SHOWED SERVICE STABILTRAK, LOW ENGINE POWER & THE CHECK ENGINE LIGHT CAME ON. I SHUT THE CAR OFF & STARTED IT AGAIN. IT DID THE SAME THING. I CUT IT OFF BUT IT DID THE SAME THING. I CUT IT OFF 1 MORE TIME BECAUSE I DID NOT FEEL SAFE DRIVING IT & WAITED A MINUTE BEFORE TRYING TO START IT AGAIN. SURPRISINGLY THE ENGINE WAS RUNNING ROUGH. I TOOK IT TO AN AUTO STORE WHERE THE CODES SHOWED THROTTLE ISSUES. I TOOK IT TO A MECHANIC. HE DID SOME ADDITIONAL TESTS & INFORMED ME THAT I HAD A BAD THROTTLE BODY. I HAD TO HAVE THIS REPLACED WHICH I WAS INFORMED THAT GM HAS HAD ISSUES WITH THROTTLE BODY & COMPONENTS. VERY DISAPPOINTED THAT THIS WOULD HAPPEN. IM CONCERNED THAT THIS MIGHT HAPPEN AGAIN OR HAPPEN DURING DRIVING.

MY DAUGHTER WAS DRIVING THIS VEHICLE HOME FROM A TRIP AND STOPPED AT A STORE. WHEN SHE RETURNED TO THE VEHICLE IT WOULD NOT MOVE. WE HAD TO HAVE THE VEHICLE TOWED AND HAD TO REPLACE THE TRANSMISSION AND REPLACE THE STEERING GEAR ON THIS VEHICLE. THE VEHICLE ONLY HAS 55,500 MILES ON IT. I DON'T FEEL THIS IS A REPAIR THAT SHOULD HAVE BEEN NECESSARY WITH THIS FEW MILES. WE ARE THE ORIGINAL OWNERS ON THE VEHICLE AND TOOK POSSESSION FROM THE DEALERSHIP ON 2/2/11. I DO HAVE THE REPAIR BILLS. WORK WAS PERFORMED ON 6/9/17.

WHILE DRIVING ON THE EXPRESSWAY AT ABOUT 65MPH MY CAR SUDDENLY ALERTED "SERVICE STABILTRAK, SERVICE TRACTION CONTROL, ENGINE POWER REDUCED" AND I WAS NOT ABLE TO UTILIZE CRUISE CONTROL ANYMORE AND IT STARTED TO SLOW DOWN TO APPROXIMATELY 40MPH. 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. AFTER READING HOW FREQUENTLY THIS HAPPENS, WHY HASN'T IT BEEN RECALLED?

NHTSA ODI 10993052

I WAS IN MOTION WHEN MY CAR NOTIFIED ME OF ENGINE REDUCE POWER AND MY CHECK ENGINE LIGHT CAME ON ALONG WITH MY TRACTION LIGHT. I RECEIVED A LETTER IN NOVEMBER OF 2015 ABOUT THIS AND TO NOTIFY THE DEALERSHIP OF THIS WHEN IT HAPPENS. I NOTIFIED THE DEALERSHIP ABOUT THIS AND THEY KEPT MY CAR FOR 2 DAYS TO FIND AN EXCUSE NOT TO TAKE CARE OF THE PROBLEM DESCRIBED IN THE LETTER. I WAS TOLD THAT THEY WOULD LOOSE $1200 IF THEY FIXED THE ISSUE DESCRIBED IN THE LETTER. I GUESS MY SAFETY AND LOYALTY AS A CUSTOMER MEANS NOTHING. THIS HAPPENED ON OR AROUND 4/04/2017

I HEAR A HORRIBLE GRIND WHEN MAKING A LEFT HAND TURN AFTER A STOP, CAR ALSO FELT LIKE IT DID NOT WANT TO GO FORWARD CAUSING HESITATION IN LEFT HAND TURN - VERY DANGEROUS WITH ONCOMING TRAFFIC. HAVE HAD IT TO MECHANIC MANY TIMES, EITHER THEY COULDNT FIND THE PROBLEM OR WOULD FIX THIS OR THAT AND THEN PROBLEMS RIGHT BACK WITHIN DAYS IF NOT HOURS. OCCASIONALLY GET SERVICE STABILITRAC AND/OR ABS LIGHTS, USUALLY LIGHTS WOULD CLEAR BY NEXT DAY WHEN I TOOK TO MECHANIC AND AGAIN THEY'D EITHER FIND NO PROBLEM OR TRY A FIX -STILL A PROBLEM. I BELIEVE THEY'RE GOING TO TRY TO REPLACE WHEEL BEARING NEXT BUT FROM ALL FORUMS I'VE READ THIS DOESN'T SEEM TO HELP PEOPLE EITHER, PROBLEM COMES RIGHT BACK, RECENTLY RACK AND PINION HAD TO BE REPLACED COSTING $700 TO FIX, WITHIN 2 DAYS I HEARD THE GRIND, HAD HESITATION ON A LEFT HAND TURN, NOTICED FLUID UNDER MY VEHICLE UPON RETURN HOME, HOPED IT WAS A/C CONDENSATION, WITHIN DAYS THE POWER STEERING IS GOING OUT AGAIN - TURNS OUT NEW RACK AND PINION IS LEAKING AND CAR IS COMPLETELY OUT IF POWER STEERING FLUID AGAIN AFTER 2 WEEKS. I CAN'T HELP BUT WONDER IF THE SOUND AND GRIND ISN'T WHAT'S CAUSING MY RACK AND PINION ISSUES AS WELL? HAVE OWNED 2 YEARS NOW WITH THIS PROBLEM CONTINUOUSLY THROUGHOUT OWNERSHIP OF THE VEHICLE. APPROX. 68K MILES ON IT WHEN PURCHASED NOW ALMOST 90K HAVE TO BE VERY CAUTIOUS MAKING LEFT HAND TURNS THAT THERE IS NO ONCOMING TRAFFIC AS HESITATION MAY CAUSE YOU TO GET HIT IF VEHICLE CAN'T TURN IN TIME. HAVE TO COMPLETELY LET OFF GAS AND TRY AGAIN SOMETIMES STILL GRINDS IF SO REPEAT IS ALL YOU CAN DO. BECOMING VERY SCARY AND COSTLY WITH NO FIX FOUND SO FAR!!! PLEASE INVESTIGATE! MULTIPLE POSTS REGARDING SAME ISSUE SOME ON NEWER MODELS, VERY MUCH A SAFETY ISSUE I CAN'T EVEN TEACH MY CHILD TO DRIVE IN THE CAR AS I AM AFRAID FOR THEIR SAFETY IN IT, AS WELL AS MY OWN SAFETY EVER TIME I TRY TO MAKE A LEFT HAND TURN.

WHEN DRIVING MY CAR ON THE FREEWAY, STABIL TRAC COMES ON, AND IT SAYS ENGINE POWER REDUCED. THIS CAUSING ME TO DRIVE IN THE SLOW LANE. THE LAST TIME THIS HAPPENED THE CAR SHUT OFF ON ME WHILE ON THE FREEWAY. MY FAMILY AND I WERE ALMOST STRUCK FROM BEHIND. WE'VE HAD THIS ISSUE BEFORE, AND WE GOT IT FIXED. I TOOK IT TO THE DEALERSHIP LAST WEEK, AND THEY WERE UNABLE TO GET ANY CODES. BASICALLY WHEN THIS HAPPENS THE CHECK ENGINE LIGHT WILL COME ON, AND IT'LL BE GONE THE NEXT DAY. THIS IS A SCARY SITUATION FOR ME BECAUSE I HAVE TO TRAVEL EVERY OTHER WEEKEND, AND I DON'T NEED THIS HAPPENING TO MY FAMILY AGAIN. I DON'T THINK WE SHOULD HAVE TO KEEP PAYING FOR THE SAME PROBLEM OVER AND OVER.

NHTSA ODI 10990686

I CONTINUE TO HAVE PROBLEMS WITH MY FRONT LEFT HUB AFTER REPLACING. I HAVE REPLACED THE WIRING HARNESS AS WELL. WONDERED IF THERE ARE SERVICE BULLETINS WITH THIS SAME ISSUE. WHILE DRIVING THE CAR IT MAKES A HORRIBLE GRINDING NOISE DESCRIBED TO ME AS THE HUB ADJUSTING THE SPEED OF ONE TIRE TO MATCH THE OTHER. IT ALSO FLASHES BRAKE ASSIST AND STABILITRACK ISSUES AS WELL AS ANTI LOCK ALERT. THIS HAPPENS MOSTLY TURNING LEFT BUT MOST RECENTLY EVEN WHILE DRIVING STRAIGHT DOWN THE ROAD.

2011 IMPALA 3.5L V6 SFI (LZE)OCTOBER, 2016 (60,104 MI) WHILE TRAVELING 60 MPH, THE VEHICLE LOST POWER. DROPPED DOWN TO 20 MPH WHILE ENGINE SURGED. DISPLAY READ, " SERVICE TRACTION CONTROL," SERVICE STABILITRACK," "ENGINE POWER REDUCED." BY FEATHERING THE GAS PEDAL, I WAS ABLE TO GET THE SPEED UP TO 40-45MPH AND DROVE 1 MILE TO GM DEALERSHIP. AT TRAFFIC LIGHT THE VEHICLE SURGED WHILE STOPPED AND NEEDED VERY FIRM BRAKING TO KEEP IT FROM SURGING AHEAD. THE DEALERSHIP STAFF "GUESSED" THAT IT WOULD BE THE THROTTLE POSITION SENSOR WITHOUT DOING DIAGNOSTIC CHECK - I ASSUMED THIS WAS A COMMON PROBLEM. I TOOK MY VEHICLE TO LDA AUTO WHERE THE OWNER/EXPERT ON VEHICLE ELECTRICAL SYSTEMS INSTALLED AN AFTERMARKET THROTTLE BODY ASSEMBLY (PART = $254); THE THROTTLE POSITION SENSOR IS AN INTEGRAL PART OF THE THROTTLE BODY ASSEMBLY SO THE ENTIRE PIECE HAD TO BE REPLACED. A "RELEARN PROCEDURE" WAS PERFORMED. ANY NEEDED ADJUSTMENTS MADE. CODE SYSTEM RESET AND TESTED. VEHICLE WAS TEST-DRIVEN. (LABOR = $80). I DROPPED MY VEHICLE OFF AT 7:00AM, GOT A RIDE TO WORK FROM SHOP STAFF, AND RECEIVED MESSAGE THAT MY VEHICLE WAS COMPLETED SAME DAY. OWNER EVEN DEDUCTED THE $20 "SHOP SUPPLIES" FEE FROM MY BILL BECAUSE HE STATED HE DID NOT USE ANY SUPPLIES. KUDOS FOR HIS HONESTY!!! TOTAL BILL CAME TO A LITTLE LESS THAN $350. OWNER SHOWED ME EXACTLY WHAT HE DID, OFFERED TO GIVE ME THE OLD PART, LET ME CHOOSE WHICH MFG TO ORDER FROM ONLINE. CAN'T SAY ENOUGH GREAT THINGS ABOUT THIS EXPERIENCE! TODAY IS 2/23/2017 AND MY IMPALA HAS NOT HAD ANY OTHER PROBLEMS SINCE THIS REPAIR; IN FACT, IT SEEMS TO BE A BIT MORE RESPONSIVE.

MY SERVICE STABILITRACK, REDUCE ENGINE POWER LIGHT CAME ON WHILE I WAS EXITING THE FREEWAY. WHEN THIS HAPPENED I HAD ALMOST NO BRAKE PEDAL. 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.

VEHICLE WILL NOT DRIVE ANY FASTER THAN 30 MILES PER HOUR. THE DASH LIGHT WARNING READS SERVICE STABILITRAK. VEHICLE SHUTTERS AND JERKS WHEN ATTEMPTING TO DRIVE IT.

IN THE MIDDLE OF TRAFFIC MY 2011 IMPALA STOP ACCELERATING. THE ENGINE WAS STILL RUNNING AND RPM WAS REACTING BUT NO ACCELERATION. I COULDN'T EVEN PULL TO THE SIDE OF THE INTERSTATE BECAUSE OF NO ACCELERATION. I'VE SEEN ONLINE THOUSANDS OF PEOPLE HAVE HAD THIS EXACT PROBLEM WITH THEIR IMPALA. I WAS NEARLY REAR ENDED AND THIS IS A VERY DANGEROUS SAFETY ISSUE.

NHTSA ODI 10947556

I HAD DRIVEN APPROX. 8 MILES ON AN EXPRESSWAY....WHEN I EXITED THE EXPRESSWAY THE CAR SLOWED DOWN AND WOULD NOT EXCEED 10 MPH. THANKFULLY, I WAS ABLE TO COAST INTO A PARKING LOT. IT WOULD NOT GO FORWARD OR IN REVERSE FROM THEN ON. WHEN I CHECKED THE TRANSMISSION FLUID IT WAS DARK AND HAD SEDAMENTS IN IT. MY VEHICLE HAS ONLY 86000 MILES. I ALWAYS HAVE THE OIL CHANGED AT THE DEALER WHERE I BOUGHT THE CAR. EVIDENTLY, THEY DIDN'T CHECK ALL THE FLUIDS LIKE THEY PROMISED.

NHTSA ODI 10945572

"TAKATA RECALL?' CHECK AIRBAG LIGHT IS ON CONTINUOUSLY. DEALER STATES IT IS NOT A SAFETY ISSUE AND WILL COST OVER $400. TO CORRECT. NOT CLEAR IF THIS LIGHT COULD BE AN ACTUAL WARNING OF MALFUNCTION CAUSING RECALL.

NHTSA ODI 10945205

THE ENGINE SPUTTERS AND BOGS DOWN. I HAVE SPENT OVER $300 TRYING TO FIGURE IT OUT, AND NO ONE CAN BECAUSE THERE IS NO DASHBOARD LIGHT THAT COMES ON. IT HAPPENS MAINLY AT A SLOW RATE OF SPEED.
