MY CHEVY MALIBU CURRENTLY HAS ABOUT 20K MILES ON IT IN ADDITION TO THAT IT IS UP TO DATE ON OIL CHANGES ETC. ABOUT 20 MINS AGO WHILE I WAS DRIVING MY VEHICLE MESSAGES ME SAYING "ENGINE POWER REDUCED" AND ALL OF A SUDDEN MY VEHICLES POWER WAS REDUCED. THANKFULLY I WASNT DRIVING ON A HIGHWAY OR ANYTHING BUT THIS WAS VERY DANGEROUS AND ALARMING TO ME. I RESEARCHED THIS PROBLEM ONLINE AND FOUND NUMEROUS COMPLAINTS ABOUT THIS FOR MY PARTICULAR MODEL AND FIND THAT VERY IRRESPONSIBLE OF GM TO NOT TAKE RESPONSIBILITY ON THIS ISSUE AND FIX IT. I ASK THAT YOU PLEASE LOOK INTO THIS SOMEONE IS GOING TO GET HURT. THANK YOU

I BOUGHT MY 2017 MALIBU IN JULY OF 2019 FROM A CHEVY DEALERSHIP. SINCE I'VE BOUGHT IT MY CAR HAS RAPIDLY SLOWED DOWN WITH NOW WARNING AND MY DASHBOARD READING ENGINE POWER REDUCED. IT'S HAPPENED 5 TIMES SINCE I GOT THE CAR ONE BEING I WAS ON THE HIGHWAY AND ALMOST GOT HIT BY A SEMI ON MY WAY TO WORK IN MORNING TRAFFIC. I LOOKED UP THIS ISSUE TO SEE WHAT COULD BE CAUSING IT AND TURNS OUT OTHER 2016-2018 MALIBU'S HAVE THE SAME ISSUES. I TOOK IT TO AUTOZONE FOR A DIAGNOSIS AND IT'S THE THROTTLE PEDAL POSITION BEING FARTHER APART THAN ALLOWED. THE DEALERSHIP IS CHARGING ME $200 TO FIX THE ISSUE AND I HAVE ONLY HAD THIS CAR FOR 6 MONTHS.

I WAS TRAVELING IN MY VEHICLE ON THE HIGHWAY GOING AT LEAST 65 TO 75 MPH AND ALL OF A SUDDEN MY VEHICLE BEATS TWO OR THREE TIMES AND ACROSS THE SCREEN CAME THE WORDS 'REDUCE ENGINE SPEED'. AT THAT MOMENT I WAS TRAVELING IN THE MIDDLE LANE AND I HAD TO SAFELY GET OVER TO THE FAR RIGHT MEDIAN IN THE MIDDLE OF TRAFFIC SAFELY TURN OFF AND WAIT AT LEAST 10 MINUTES TO START IT BACK UP. WHEN I STARTED MY VEHICLE BACK UP AGAIN I STILL RECEIVED THE SAME MESSAGE. I THEN WAITED EVEN LONGER AND EVERYTHING WAS OK BUT EVENTUALLY THE SAME ISSUE CONTINUED TO HAPPEN SEVERAL TIMES. I TOOK MY VEHICLE TO GET CODED AND THE CODES THAT WERE GIVEN TO ME WERE 2122, 2123, 2101. IT'S UNSAFE FOR THIS TO HAPPEN ESPECIALLY I HAVE A CHILD THIS IS NO SAFE FOR ME.

MY CAR WENT FROM GOING 70 MPH TO 40 MPH AND WOULDN'T GO ANY HIGHER. I IMMEDIATELY GOT OFF THE FREEWAY TOOK PICTURES OF THE LIGHTS. LUCKILY I HAVE A ANTI LEFT DEVICE THAT READS OFF CODES FOR MY CHECK ENGINE LIKE CODE P2138 IS WHAT CAME UP. THIS IS EXTREMELY DANGEROUS, I HAD MY [XXX] CHILD IN THE CAR WITH ME AND WAS ALMOST REAR ENDED DUE TO LOSS OF POWER FROM SUCH A HIGH SPEED. *DL 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).

WHILE DRIVING MY 2017 CHEVROLET MALIBU ON THE HIGHWAY WITH MY SON IN THE CAR, THE DRIVER SCREEN DASH FLASHED A MESSAGE 'ENGINE POWER REDUCED', THE CHECK ENGINE LIGHT TURNED ON, AND THE CAR IMMEDIATELY LOST POWER MAKING IT DIFFICULT TO DRIVE SAFELY. AFTER THIS HAPPENED, MY CAR WOULD NOT EXCEED 45 MPH AND WOULD NOT SHIFT. AFTER PULLING MY CAR TO THE SIDE OF THE BUSY HIGHWAY AND LETTING IT SET, I WAS ABLE TO GET MY CAR TOWED TO MY HOME. THIS HAS SINCE HAPPENED FIVE ADDITIONAL TIMES AND IS HAPPENING AT A MORE RAPID RATE. I TOOK MY CAR THE OREILLEYS AND AUTOZONE TO HAVE THEM RUN A GENERAL DIAGNOSTIC CHECK AND THE ERROR CODE BEING RETURNED WAS 'P2138' - 'THROTTLE/PEDAL POSITION SENSOR/SWITCH D / E VOLTAGE CORRELATION'. I THEN SET UP AN APPOINTMENT WITH THE CHEVROLET DEALERSHIP, WHERE TECHNICIANS ALSO RAN A MORE THOROUGH DIAGNOSTIC TEST AND FOUND MY CAR NEEDED A NEW ACCELERATOR PEDAL POSITION SENSOR. THIS PART IS NOT FUNCTIONING AS IT IS SUPPOSED TO AND AT THE VERY LEAST IS AN EXTREME SAFETY HAZARD.

CAR WILL INDICATE 'ENGINE POWER REDUCED' AND WILL ABRUPTLY REDUCE SPEED. THIS IS A MAJOR SAFETY CONCERN NOT ONLY TO MYSELF BUT OTHER DRIVERS ON THE ROAD AS WELL. WHY IS THERE NO RECALL FOR THIS PROBLEM? I SEE IT IS A MAJOR PROBLEM WITH THESE MODELS OF CHEVY MALIBU. HAPPENS EVERYDAY, MOST OF THE TIME MORE THAN ONCE. MY COMMUTE TO WORK IS ABOUT 25MIN AND IT DID IT 3 TIMES TODAY.

ENGINE LIGHT ON CONTINUALLY AND NEVER WENT OFF; I DROVE TO DEALER WHO SAID THE GAS CAP AREA OF FUEL LINE WAS LEAKING; NEEDS TO BE REPLACED THEY SAID AND TRIED TO ORDER IT FROM GM BUT THEY DO NOT HAVE THE PART; THEY ORDERED THE PART AND CANNOT TELL ME WHEN IT IS COMING. THEY COULD NOT ADVISE ME ON THE SAFETY OF THIS CONDITION. I KNOW SOMEONE WHO HAD A SIMILAR PROBLEM WITH THEIR MODEL CAR. CAN I DRIVE THIS OR SHOULD THE DEALER GIVE ME A LOANER? I AM STILL UNDER THE 3 YEAR BUMPER TO BUMPER WARRANTY. WE HAVE ALWAYS HAD PROBLEMS FILLING THE CAR AND IT IS NEVER COMPLETELY FULL. WE HAVE BROUGHT IT TO DEALER SEVERAL TIMES ABOUT THIS WITH NO ADVISE. THEY DID RECALIBRATE ONE TIME. THEY SAID IT WAS AN ISSUE WITH THE DASH BOARD REPORTING LESS GAS THAN IS IN THE TANK. PLEASE LET ME KNOW ABOUT THIS AS WE CONTINUE TO DRIVE THE CAR.

FOR THREE WEEKS I HAVE BEEN GETTING A "SHIFT TO PARK" ERROR WHEN I PLACE CAR IN PARK. IT PREVENTS ME FROM FULLY TURNING CAR OFF AND WILL NOT ALLOW DOORS TO LOCK. I HAVE TO PLAY WITH THE SHIFTER TO GET THE WARNING TO COME OFF. LAST WEEK IT WAS IN THE SHOP AT BASIL CHEVROLET IN DEPEW, NY AND THEY REPLACED THE SHIFT RELAY AND IT IS STILL DOING IT. TODAY WHILE DRIVING DOWN THE HIGHWAY MY CAR SUDDENLY SHOWED THE CHECK ENGINE LIGHT, THE TRACTION CONTROL LIGHT, SLOWED DOWN TO APPROXIMATELY 10-15 MILES PER HOUR AND SHOWED "REDUCED ENGINE POWER" WARNING ON THE DASHBOARD. I WAS IN THE MIDDLE OF RUSH HOUR TRAFFIC. I WAS ABLE TO GET INTO A PARKING LOT BUT THE CAR WOULD NOT SHUT OFF AND THE "SHIFT TO PARK" WARNING SHOWED. FINALLY GOT THAT ERROR TO GO OFF AND SHUT OFF CAR. CAR WAS ABLE TO RESTART WITH ONLY THE ENGINE LIGHT ON. STAYED ON FOR THE NEXT 35 MILES. JUST WENT BACK OUT AT LUNCH TIME AND NOW NO LIGHTS AND IT WAS DRIVING FINE UNTIL I TRIED SHUTTING OFF AND THE "SHIFT TO PARK" WOULDN'T GO OFF NO MATTER HOW MUCH I TRIED TO WIGGLE THE HANDLE. CAR GOING BACK TO DEALER AT 5PM.

ON JULY 22, 2019 WHILE OUT OF TOWN, MY CAR WENT INTO REDUCED ENGINE POWER MODE, EVERYTHING LOCKED UP AND THE CAR CUT OFF. THE CAR WOULD NOT START BACK UP. I HAD THE CAR TOWED TO THE CLOSEST SHOP WHERE IT WOULD SIT FOR ABOUT A MONTH AND A HALF. I WAS TOLD THAT INITIALLY IT WAS A SENSOR, THEN COME TO FIND OUT THE CAMSHAFT NEEDED TO BE REPLACED. IT TOOK A FEW WEEKS TO GET THE PARTS AS THEY SAID THEY WERE ON BACK ORDER. FINALLY I GET THE MONEY TO PICK THE CAR UP. UPON GETTING INTO THE CAR ON OCTOBER 12, WHILE STILL AT THE DEALERSHIP THE ENGINE LIGHT CAME ON. NOW I AM TOLD THAT THE SENSORS AND PISTONS NEED TO BE REPLACED. THE CAR HAS 89,000 MILES ON IT AND OVER ALL THE TOTAL REPAIRS WILL BE OVER SEVEN THOUSAND DOLLARS. I HAVE SENT SOME DOCUMENTATION TO THE DEALERSHIP WITH REGARDS TO CUSTOMER SATISFACTION PROGRAM NUMBER N182195660 ATTACHED BELOW. THIS DESCRIBES EVERYTHING THAT HAS BEEN WRONG WITH MY CAR THIS TIME IN THE SHOP AND THE REPAIRS THAT THEY NEED DO WITH THE PISTONS AS OF NOW. I HAVE REACHED OUT TO GM TO OPEN A CASE TO SEE IF MY CAR COULD BE PART OF THIS NOTIFICATION, THOUGH THEY HAVE INITIALLY TOLD ME ITS NOT, ITS TOO OBVIOUS THAT THE CAR MEETS EVERYTHING THAT IS DESCRIBED IN THE NOTICE.

NHTSA ODI 11268644

REDUCED ENGINE POWER IS A NORM FOR THESE NEW CHEVY MALIBU'S MY ENGENDER IS REDUCING POWER AGAIN. THEY CHARGES ME $345 LAST DECEMBER 3018 TO REPLACE THE ACCELERATOR PEDAL AND THIS OCTOBER 2019, IT'S DOING THE SAME THING. IT WILL REDUCE SPEED ON HIGHWAY UNDER 50 MPH AND I COULD HAVE BEEN HIT BY OTHER CARS IF THEY DID NOT NOTICE.
