What 687 owners told NHTSA about the 2017 Chevrolet Malibu Eco

CRUISING TO WORK ON I-93 IN CONCORD, NH TRAVELING AROUND 70 MPH AND IT JUST LOST POWER AGAIN!!! THE "REDUCE ENGINE POWER LIGHT" CAME ON AND VEHICLE WOULD ONLY GO 25-30 MPH. THANKFULLY THERE WASN'T A VEHICLE BEHIND ME. I WOULD HAVE BEEN "KILLED". DROPPED VEHICLE TO CHEVY DEALER. THEY FOUND P2127 FOR ACCELERATOR PEDAL POSITION SENSOR FAILURE, REPLACED GAS PEDAL, CLEARED CODES, ROAD TESTES. MILEAGE 76,473. THIS IS ABSOLUTELY AND TOTALLY UNSAFE AND UNACCEPTABLE. THE VEHICLE IS IN THE SHOP AGAIN FOR THE FOURTH TIME, SAME ISSUE. I WILL REPORT EACH INCIDENT SEPARATELY. *TR

DROVE 30 MILES SINCE THE LAST TIME IT WAS IN THE SHOP FOR THIS ISSUE. STARTED MY VEHICLE IN THE DRIVEWAY AND THE "REDUCED ENGINE POWER LIGHT" CAME ON. SO FRUSTRATING AND A WASTE OF TIME!! I IMMEDIATELY DROVE BACK TO DEALERSHIP FOR REPAIR. A BUNCH OF CODES CAME UP. THEY REMOVED AND REPLACED THE ECM. ROAD TESTED FOR 45 MILES BEFORE RETURNING VEHICLE. *TR

ENTERED ON-RAMP TO HEAD SOUTH ON I-93 AND HALF-WAY UP THE RAMP IT HAPPENED AGAIN. THE "REDUCE ENGINE POWER LIGHT" CAME ON AND THE SPEED DROPPED IMMEDIATELY. I COULDN'T TURN AROUND AND GO HOME, SO I CONTINUED DOWN THE INTERSTATE GOING IN AND OUT OF THE BREAKDOWN LANE TO AVOID UPCOMING TRAFFIC BEHIND ME. IMMEDIATELY DROVE TO DEALERSHIP AND DROPPED OFF VEHICLE. I HAVE BEEN WORKING FROM HOME SINCE MARCH 15, 2020, SO I PROBABLY PUT APPROXIMATELY 200 MILES ON THE VEHICLE SINCE THE ECM WAS REPLACED. THERE IS NO RHYME OR REASON THAT THIS CONTINUES TO HAPPEN. HOWEVER, THIS IS ABSOLUTELY AND TOTALLY UNSAFE AND UNACCEPTABLE!!! I'M THINKING PEOPLE HAVE DIED BECAUSE OF THIS ISSUE - IT IS SO UNSAFE!!!! I AM WAITING TO HEAR BACK FROM THE DEALERSHIP.

WHILE DRIVING IN HEAVY INTERSTATE TRAFFIC MY VEHICLE BEGAN TO IDLE ROUGHLY AND CUT OFF TWICE IN TRAFFIC. ONCE IT CRANK FULLY IT ACCELERATED AT A HIGH RATE OF SPEED JUST BARELY MISSING THE CAR IN FRONT OF ME. WHEN I WENT TO REPAIR MY VEHICLE I WAS TOLD THAT THIS IS A WIDE KNOWN ISSUE WITH NO RECALL IN PLACE. I COULD HAVE LOST MY LIFE THAT DAY. *TR

I WAS DRIVING ON THE HIGHWAY TODAY GOING AROUND 70 MPH AND MY CAR DISPLAYED "REDUCED ENGINE POWER" AND IMMEDIATELY LOST POWER AND DECELERATED. IT IS NOT THE FIRST TIME THAT IT HAS DONE THIS BUT IT WAS THE FIRST TIME DRIVING AT THAT HIGH RATE OF SPEED. THE OTHER TIMES IT HAS HAPPENED ON CITY STREETS WHEN I WAS GOING MORE THAN MAYBE 40 MPH. EACH TIME IF I TURN THE CAR OFF AND THEN WAIT A FEW SECONDS AND START IT AGAIN, THE REDUCED ENGINE POWER DISPLAY IS GONE AND I DONT HAVE ANYMORE IMMEDIATE ISSUES WITH IT, SOMETIMES FOR DAYS OR WEEKS AT A TIME. I HAVE NOTICED ONLINE THAT SEVERAL PEOPLE HAVE EXPERIENCED SOMETHING SIMILAR WITH THEIR 2017 CHEVROLET MALIBU.

WHILE DRIVING 60MPH ON THE HIGHWAY, MY CAR BEGAN BEEPING AND DISPLAYED 'REDUCED ENGINE POWER' ON THE SCREEN. THE TRACTION LIGHT AND ENGINE LIGHT ALSO CAME ON. THE CARS SPEED WAS IMMEDIATELY REDUCED ALMOST CAUSING A SERIOUS ACCIDENT AS I WAS IN THE LEFT LANE ON THE HIGHWAY WITH A SEMI BEHIND AND BESIDE ME. I WAS ABLE TO MANEUVER TO THE SHOULDER. I HAD TO RESTART THE CAR TWICE IN ORDER TO BE ABLE DRIVE IT HOME. THIS WAS AN ABSOLUTELY TERRIFYING SITUATION. THE CHECK ENGINE LIGHT IS STILL ON. UPON GOOGLING THIS ISSUE, MANY PEOPLE HAVE HAD THIS PROBLEM AND THERE HAS NOT BEEN A RECALL! IF MY REACTION TIME WASN'T A FAST AS IT WAS TODAY, I WOULD HAVE BEEN SERIOUSLY HURT, OR WORSE. GM NEEDS TO ADDRESS THIS.

I WAS ON A HIGHWAY IN WARREN OH DRIVING TO WORK TRAVELING AT 65 MPH IN THE LEFT LANE. A MESSAGE APPEARED AND SAID LOSS OF ENGINE POWER AND THE AT WENT FROM 65 TO 20 IN 1 SECOND. THERE WERE VEHICLES BEHIND ME AND BESIDE ME. I WAS ALMOST REAR ENDED AND WHEN I TRIED TO GET OVER TO THE SIDE OF THE ROAD I WAS ALMOST SMASHED BY A SEMI. AS WELL AS THAT MESSAGE IT THEN STATED STEERING ASSIST INACTIVE SO IT WAS THEN HARD TO TURN MY WHEEL AS IF THERE WASN'T ENOUGH OF A PROBLEM. THANK GOD I AM OK BUT SOMEONE ELSE MAY NOT BE SO LUCKY. THERE ARE NUMEROUS COMPLAINTS THAT I SEE ON THE INTERNET ABOUT THIS ISSUE. HOW IS THERE NOT A RECALL. GM SHOULD BE RESPONSIBLE FOR THESE REPAIRS. I JUST PURCHASED THIS VEHICLE IN NOV 2019.

REDUCED ENGINE POWER FIRST TIME THIS HAPPENED I WAS MAKING A U TURN AT SLOW SPEEDS WHEN MY DASH DISPLAYED ' REDUCED ENGINE POWER' CHECK ENGINE LIGHT CAME ON AS WELL AS TRACTION CONTROL LIGHT . I PULLED OVER TURNED MY CAR OFF AND BACK ON A FEW MINS LATER LATER LIGHTS WENT AWAY AND CAR DROVE FINE . ( NOVEMBER 2019 ) SECOND TIME WAS MID FEBRUARY 2020 I WAS DRIVING ABOUT 40 MPH WHEN SAME THING HAPPENED . DASH LIGHTS CAME ON REDUCED ENGINE POWER CAME BACK ON AND CAR SLOWED DOWN TO LESS THE 20 MPH WITHIN SECONDS . ONCE AGAIN I HAD TO PULL OVER TURNED MY CAR ON/OFF ABOUT 3 TIMES IN 20 MINS FOR LIGHT TO GO AWAY AND CAR DRIVE NORMAL AGAIN . THIRD TIME TODAY 2/27/20 AT MAYBE 10 MPH MY DASH LIT UP ONCE AGAIN CHECK ENGINE LIGHT DID NOT GO AWAY THIS TIME . BUT CAR DROVE FINE AFTERWORDS LUCKILY IT HASN'T HAPPENED ON HIGHWAY SPEEDS OR WITH MY DAUGHTER IN THE CAR . ALL THIS IN THE LAST 3 MONTHS I BOUGHT MY CAR WITH 20 MILES JUNE 1ST 2017 AND CURRENTLY HAS 38K MILES . THIS DEFINITELY HAS TO BE FIXED BEFORE IT CAUSES SERIOUS ACCIDENTS !

I WAS DRIVING STRAIGHT AT 47MPH ON A MAJOR STREET IN DENVER AND THE CHECK ENGINE LIGHT CAME ON. AT THE SAME TIME, THE DISPLAY READ "ENGINE POWER IS REDUCED" AND I LOST ALL ACCELERATION. MY SPEED DROPPED TO ABOUT 20MPH VERY QUICKLY (5 TO 8 SECONDS). LUCKILY THERE WAS RELATIVELY LIGHT TRAFFIC. I PULLED INTO AN AUTOZONE THAT WAS AT THE NEXT INTERSECTION AND THEY READ THE ERROR CODE P2138. COME TO FIND OUT THIS SHOWS AN ERROR WITH THE THROTTLE/PEDAL POSITION CENSOR. I GOT BACK IN MY CAR TO DRIVE HOME AND WITHIN 30 SECONDS, THE CHECK ENGINE LIGHT WENT OFF AND MY CAR RAN LIKE NORMAL. I'M STILL VERY WORRIED ABOUT THIS SENSOR HOWEVER. WHEN I LOOKED THIS UP ONLINE TONIGHT, I CAME TO FIND OUT THIS IS A COMMON PROBLEM YET CHEVY HAS DECIDED NOT TO RECALL THIS PART. DOING MORE RESEARCH LEAD ME TO THE CLASS ACTION LAWSUIT WHICH HAS BEEN BY ROTHSCHILD V. GENERAL MOTORS LLC, CASE NO. 1:19-CV-05240, IN THE U.S. DISTRICT COURT FOR THE EASTERN DISTRICT OF NEW YORK. FROM WHAT I READ, AND KNOWING THAT I DRIVE 35,000 MILES PER YEAR FOR WORK, I BELIEVE THIS COULD BE A HUGE IF THIS WERE TO HAPPEN WHEN I'M DOING 75+MPH ON THE INTERSTATE. I URGE THE NHTSA TO REVIEW THIS VERY DANGEROUS SITUATION CAREFULLY AND STRONGLY RECOMMEND YOU HAVE CHEVY DO THE RIGHT THING AND GET THIS PART FIXED AND REPLACED TO KEEP US DRIVERS SAFE!!

WHEN DRIVING DOWN A HIGHWAY TO DROP OFF KID AT SCHOOL, THE CAR SOMETIMES SLOWS DOWN ON ITS OWN AND A MESSAGE COMES ON STATING ENGINE POWER REDUCED. AT 6:30 AM IN THE MORNING WHEN IT'S STILL DARK, THIS IS GOING TO CAUSE A CAR CRASH SOONER OR LATER. BUT DEALER SAYS THERE IS NO RECALL.

AT LESS THAN 32K MILES I"VE HAD ISSUE WITH THE SHIFT TO PARK INDICATOR, THE RADIO RANDOM ON AND OFF REGARDLESS IF CAR IS RUNNING OR PARKED AND OFF AND NOW MULTIPLE INDICATORS FOR AN EMISSION ISSUE CAR WILL SUDDENLY LOOSE POWER OR STOP. I HAVE TAKEN CARE FOR SERVICE ON REGULAR BASIS AND HAVE HAD SERVICE REPAIRS DONE TWICE TO SUPPOSEDLY FIX COMPUTER BOARD. UNFORTUNATELY, SERVICE EITHER SAYS THEY HAVE REST IT OR CAN'T FIND ISSUES I DESCRIBE. I WILL PARK THE CAR AND LET GM HAVE IT BEFORE I GET KILLED IN TRAFFIC!!!!

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).

THE CAR RANDOMLY WILL REDUCE ENGINE POWER, LOWERING SPEEDS TO 20MPH OR LESS. THIS HAPPENS UNEXPECTEDLY. THIS HAS OCCURED OVER 20 TIMES OVER THE PAST 7 DAYS, INCLUDING ON THE HIGHWAY. I WAS DRIVING ON THE HIGHWAY AT 70MPH AND THE IMMEDIATELY DROPPED TO 20MPH, CAUSING ME TO SWERVE TO THE SHOULDER AND ALMOST WAS HIT BY THREE ON COMING VEHICLES AT HIGH RATES OF SPEED.

ENGINE POWER REDUCED WARNING CAME ON WITH ENGINE LIGHT AND TRACTION LIGHT CAR SPEED DROPPED

MY VEHICLE HAS 6X,XXX MILES ON IT. I FIRST ENCOUNTERED A "REDUCED ENGINE POWER" MESSAGE ON NOVEMBER 27, 2019 AFTER DRIVING 15 MILES, TURNING THE CAR OFF FOR ABOUT 30 MINUTES, AND STARTING THE CAR AGAIN. I CALLED ON-STAR TO RECEIVE A DIAGNOSTIC REPORT, WHICH RETURNED A P2138 CODE. I LIMPED THE CAR HOME ON A RURAL ROUTE WITH REDUCED POWER. ONCE HOME, THE CAR WAS TURNED OFF FOR ABOUT 5 MINUTES. WHEN I TURNED THE CAR ON, THERE WAS A CHECK ENGINE LIGHT BUT IT RAN FINE. THE LIGHT EVENTUALLY TURNED OFF. THE CAR RAN FINE UNTIL THE EVENING OF MONDAY, DECEMBER 2, 2019. THIS TIME THE REDUCED ENGINE POWER CONDITION OCCURRED AS I WAS IN TRAFFIC COMMUTING HOME FROM WORK, MOVING AT A LOW SPEED. LUCKILY THE ROAD WASN'T BUSY AND I WAS ABLE TO PULL INTO A GAS STATION. I POWERED THE CAR OFF AND BACK ON, AND IT RAN FINE ALL THE WAY HOME. BASED ON SOME RESEARCH ON THE INTERNET, I BELIEVE THE ACCELERATOR PEDAL POSITION SENSOR IS FAILING. THIS APPEARS TO BE A WIDESPREAD ISSUE WITH THESE VEHICLES. I WILL BE REPLACING THE PART ON MY OWN. THE REPLACEMENT PART WAS VERY HARD TO FIND, SUPPORTING MY SUSPICION THAT THIS IS A WIDESPREAD AND LIKELY AN ISSUE THAT GM IS AWARE OF.

NHTSA ODI 11287234

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.
