What 720 owners told NHTSA about the 2017 Chevrolet Malibu Hev

AS I WAS DRIVING ON THE INTERSTATE MY CHECK ENGINE AND TRACTION CONTROL LIGHTS FLASHED ON. ALL OF A SUDDEN THE ENGINE POWER DOWN LIGHT LIT UP AND I COULDN'T GO ABOVE 30 MPH. THIS HAS HAPPENED TWICE IN THE LAST WEEK. VERY SCARY WHEN YOU ARE DRIVING 60-70 MPH ON THE INTERSTATE.

DRIVING AT ABOUT 55MPH THEN WITHOUT WARNING MESSAGE ON INSTRUMENT CLUSTER SHOWED LOW POWER ENGINE MODE WITH EMISSION WARNING ICON ILLUMINATED. SPEED DROPPED ALMOST INSTANTLY FROM 55MPH TO ABOUT 35MPH!!!!! SETTING STAGE FOR POSSIBLE REAR END COLLISION BUT WAS LUCKY THIS TIME.

CAR IS BURNING MORE FUEL THAN USUAL AND IT IS HESITANT TO TAKE OFF; LIKE THE TURBO IS NO LONGER WORKING.

WHEN IT RAINS, THE FLOOR MATS GET WET UNDER THE BRAKE AND ACCELERATOR. IT HAPPENS EVERY TIME IT RAINS; THEY FIXED THE ISSUE WITH THE RAIN LEAKING IN THE TRUNK BUT NOT WITH THE RAIN LEAKING INSIDE THE CAR.

WHILE DRIVING ON A CITY STREET APPROACHING A ROUNDABOUT THE ENGINE WARNING LIGHT CAME ON, THE CAR REDUCED IT'S ENGINE POWER, AND THE TRACTION CONTROL SENSOR CAME ON

NHTSA ODI 11298040

ENGINE POWER REDUCED. ENGINE POWER REDUCED. AT FIRST IT SEEMED TO HAPPEN WHEN IT WAS RAINING, BUT ON DRY DAYS NO PROBLEMS. THE ENGINE LIGHT COMES ON, AND DISAPPEARS A FEW HOURS LATER. THE DEALERSHIP ACTS AS IF THEY CAN'T TELL YOU ANYTHING ONCE THE WARNING AND ENGINE LIGHT TURN OFF. LATELY IT'S BEEN HAPPENING MORE FREQUENTLY, SO I WAS FINALLY ABLE TO GET IT READ. ERROR CODES P2138 AND P2127, BOTH REFERENCING THROTTLE/PEDAL POSITION SENSOR. SEEMS TO BE THE ONLY COMPLAINT I SEE ON HERE. I ALSO HAVE READ ABOUT LAW SUITS BEING FILED REGARDING THIS AS WELL.

VEHICLE ABRUPTLY SLOWED IN HEAVY TRAFFIC FOR NO APPARENT REASON. VEHICLE WAS DIAGNOSED AS HAVING A FAULTY ACCELERATOR PEDAL. PART WAS REPLACED AT OWNERS EXPENSE 14 MONTHS INTO THE LIFE OF THE CAR. 8 MONTHS LATER THE VEHICLE STARTED TO DO THE SAME THING FOR THE NEXT 5 MONTHS, SOMETIMES 3 TO 4 TIMES IN ONE DAY OR NOT AL ALL FOR SEVERAL WEEKS. CAR WAS AGAIN PRESENTED TO DEALER FOR DIAGNOSTIC AND IT SHOWED THAT THE SAME FAULT OCCURRED. THIS IS A SEVERE SAFETY ISSUE THAT NEEDS TO BE ADDRESSED BY GENERAL MOTORS. FAULT CODES P2138 FOR ACCELERATOR PEDAL, C0242 AND U0401 FOR TRACTION CONTROL SYSTEM. NEITHER OF THESE FAULTS WERE ADDRESSED BY THE DEALER DURING THE REPAIR.

I WAS LEAVING WORK AND GOT 5 MINUTES INTO MY DRIVE AND I HAD A WARNING LIGHT COME ON IN MY MALIBU WHILE I WAS IN MOTION DRIVING STRAIGHT IN TOWN. IT INDICATED "ELECTRIC STEERING ISSUES" IT WAS ON FOR NO MORE THAN 5-10 SECONDS THEN IT TURNED OFF AUTOMATICALLY. ALLTHOUGH THIS WARNING WENT AWAY, I DID NOT FEEL SAFE SO I PULLED OVER AND STARTED DOING SOME RESEARCH ON MY MALIBU. I DID NOT FIND ANYTHING THAT MADE ME FEEL UNSAFE TO FINISH MY DRIVE HOME, BUT I DO WANT TO RAISE ATTENTION TO THIS SO IT CAN BE LOOKED INTO SO THIS DOESNT HAPPEN TO OTHER PEOPLE.

WHILE DRIVING GOING AT LEAST 70 MPH I GET A ENGINE POWER REDUCED MESSAGE AND IT START HAPPENING EVERY 10 MINUTES NOW AS SOON AS YOU TURN THE CAR ON IT SAYS ENGINE POWER REDUCED AND WON'T GO OVER 30 MPH. HAD IT HOOKED UP TO A MACHINE AND WAS TOLD IT WAS MY ACCELERATOR WHICH APPARENTLY IS A ISSUE IN THE 2017 MALIBU'S

MY 2017 CHEVY MALIBU HAS PERIODICALLY SHOWED A REDUCED POWER MODE ALERT IN THE DASH WHILE DRIVING AND THEN THE CAR DROPS DOWN TO UNDER 40 MPH AND WHEN I PUSH THE GAS IT WON'T ACCELERATE. THE CHECK ENGINE LIGHT COMES ON EVERY TIME BUT WITHIN DAYS IT GOES OFF AND DRIVES FINE UNTIL IT HAPPENS AGAIN WITH NO WARNING. MY HUSBAND WAS DRIVING 70 ON THE INTERSTATE WHEN IT FIRST HAPPENED AND ALMOST WRECKED BECAUSE OF IT! I HAVE CALLED THE DEALERSHIP WHERE THEY TELL ME THEY DON'T KNOW WHY IT'S DOING IT AND TO JUST BRING IT IN. I HAD THE ENGINE CODES PULLED AND WAS TOLD IT WAS A SENSOR AND ACCELERATION PEDAL. I'VE READ SEVERAL POSTS ABOUT WHAT'S WRONG WITH IT AND EVERYONE SAYS EVEN AFTER HAVING IT FIXED IT GOES OUT AGAIN WITHIN TIME. IT'S REALLY DANGEROUS WHEN YOURS DRIVING AT HIGH SPEEDS WITH TRAFFIC THEN THE CAR RANDOMLY TRY'S TO SHUT DOWN AND CHEVY IS NOT CONCERNED AT ALL ABOUT FINDING A PERMANENT FIX!

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.

WITHIN 1 YEAR I BOUGHT BRAND NEW HYBRID MALIBU CAR FROM CHEVY DEALER, I HAD EXPERIENCED DEAD 12V BATTERY. DEALER REPLACED THE BATTERY WHICH I PAID EVEN THOUGH I THOUGHT IT SHOULD BE WITHIN WARRANTY. LAST NIGHT I EXPERIENCED 3RD DEAD BATTERY AGAIN AFTER I PARKED THE CAR FOR 7 HRS OFFICE WORK. THE 2ND TIME DEAD BATTERY OCCURED WAS LAST JUNE 2019 ONLY, DEALER ALSO REPLACED THE BATTRY. ITS A 3RD TIME THAT I EXPERIENCE DEAD BATTERY (STATIONARY/PARKED) FOR BRAND NEW CAR 2017 HYBRID MALIBU WITHIN 2 YEARS. OBVIOUSLY ITS NOT THE BATTERY ISSUE BUT ITS DESIGN OF ELECTRICAL SYSTEM. BEFORE AND DURING THE BATTERY ISSUE, I GOT STABILITRAK LIGHT ON AND STEERING ASSIST IN REDUCED ALARM AS WELL. I JUST WANT TO VENT MY FRUSTATION WITH THIS BRAND NEW CAR. HOPE OTHER CAR OWNERS WILL BENEFIT FROM THIS INFO. FOR 10 YEARS I NEVER HAD BATTRY ISSUE ON MY PREVIOUS CAR. THANKS

EMGINE REDUCED SPEED HAS BEEN COMIN ON FOR A WHILE ON MOST CHEVY MODELS. THE CAR IMMEDIATELY SLOWS ON THE FREEWAY DURING TRAFFIC AND ANYWHERE. THE SEATBELTS DO NOT ALWAYS ATTACH.

NHTSA ODI 11290146

THE ELECTRICAL BLINKS OUT . ENGINE REDUCED SPEED IS A PROBLEM AND IS VERY DAMGEROUS I WAS ALMOST HIT ON THE FREEWAY. THIS CAR IS A DUD AND MOST MODELS LIKE IT HAVE THE SAME PROBLEM.

NHTSA ODI 11290148

MY CAR WILL RANDOMLY GO INTO ENGINE REDUCED POWER MODE CAUSING MY CAR TO DROP FROM WHATEVER SPEED I'M AT TO 30-40MPH, ALMOST CAUSING AN ACCIDENT. IT'S HAPPENED ON MULTIPLE OCCASIONS.

THEY DID NOT HAVE ANY AND SAID IT MAYBE MONTHS BECAUSE OF THIS BIG PROBLEM. MY CAR WAS DOWN 15 DAYS FOR THIS PROBLEM BEFOR IT WAS FIXED.

DURING THE COLD THE CAR WILL NOT TURN ON, WILL SHOW A STABILITRAK PROBLEM AND THE TRANSMISSION LIGHT TURNS ON. WHEN IT IS ON AND YOU DRIVE IT, IT WILL AUTOMATICALLY TURN OFF AND STAY OFF AT A RED LIGHT OR WHENEVER YOU PRESS THE BRAKE. I HAVE TWO OTHER FRIENDS WHO OWN THE SAME CAR AND IT DOES THE SAME , WHICH MAKES ME ASSUME A MANUFACTURER PROBLEM OF CARS NOT TURNING ON IN THE COLD/ SENSOR ISSUE.

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

NHTSA ODI 11289032

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.

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.
