AFTER MY 'RECALL' REPROGRAMMING UPDATE ON THE ECM... A MONTH OR 2 LATER, I STARTED TO HAVE LOSS OF POWER ISSUES WHILE DRIVING. GOT HOME IT SAT FOR A COUPLE OF MINS, THEN WENT AWAY. HAPPENED AGAIN. HAD MY CAR SCANNED TO SEE WHAT THE CODE WAS, AN 'APPS' P2138 CODE, ACCELERATOR PEDAL POSITION SENSOR ISSUE. IT HAPPENS WHILE DRIVING, WHEN IT HAPPENS CRUSE CONTROL TURNS OFF, AND TRACTION CONTROL LIGHT COMES ON PLUS THE CHECK ENGINE LIGHT. THIS CAN BE A SAFETY ISSUE WHILE TRYING TO MERGE ONTO HIGHWAY TRAFFIC... THIS HAD HAPPENED TO ME SEVERAL TIMES... FIRST TIME WAS AFTER A LONG DAY DRIVING, THEN A FEW DAYS LATER AFTER A VERY COLD NIGHT. THEN NOTHING, SEVERAL HUNDRED MILES NO ISSUE. THEN DROVE 120 MILES AND IT HAPPENED AGAIN ON 2-13-2020. AND TWICE TODAY 2-21-20202. IT ONLY HAPPENED TWICE DURING A TURN.

WHILE DRIVING, ENGINE GOES INTO REDUCED POWER MODE WITHOUT WARNING AND UNABLE TO MAINTAIN SPEED. CHECK ENGINE LIGHT STARTS BLINKING AND ACCELERATION IS LOST. THIS HAPPENED TWICE, ON A HIGHWAY AND ON A ROAD. GETTING TO THE SIDE OF THE ROAD SAFELY WAS VERY DIFFICULT. ONSTAR SENT AN EMAIL NOTIFICATION OF THE CRITICAL FAILURE.

THE STEERING WILL "STICK" AT THE TOP AFTER TRAVELING IN A STRAIGHT LINE FOR A PERIOD OF TIME. THIS WILL HAPPEN ON THE HIGHWAY AN IN THE CITY BUT IS MORE PRONOUNCED ON THE HIGHWAY. I HAVE REPEATEDLY TAKEN IT TO THE DEALER AND THEY CANNOT DUPLICATE THE ISSUE EVEN THOUGH IT HAPPENS FREQUENTLY. SEEMS TO BE WORSE IN COLDER WEATHER. THIS IS INDEED A SAFETY ISSUE BECAUSE WHEN IT RELEASES YOU OVER CORRECT YOUR STEERING AND WANDER AROUND IN YOUR LANE. IT HAS BEEN DOING THIS ALMOST SINCE NEW AND IT NOW HAS 18,500 MILES ON IT.

THE EXCELLARATOR SENSOR IS BAD AND KEEPS POWERING DOWN ENGINE EVEN ON THE FREEWAY

NHTSA ODI 11296621

FAULTY ACCELERATOR POSITION SENSOR. PART IS SUPPOSE TO LAST THE LIFE OF THE CAR. THE CAR HAS 60000 MILES ON IT. IT THROWS THE CHECK ENGINE LIGHT AND REDUCES POWER TO THE VEHICLE AT HIGHWAY SPEEDS. THIS IS VERY DANGEROUS AS YOU CANT ACCELERATE TO GET OUT OF TRAFFIC OR TO GET ACROSS THE LANES. YOU JUST HAVE TO COAST TO SAFETY.

I JUST GOT A 2018 CHEVY MALIBU. I WAS DRIVING HOME FROM WORK TODAY AND MY CAR JUST STOPPED AND A REDUCE ENGINE POWER MESSAGE FLASHED ACROSS MY SCREEN. I COULD HAVE BEEN KILLED WHEN I CAR CUT OFF IN THE MIDDLE OF A BUSY STREET. I HAVE JUST SEEN ALL OF THE MESSAGES ABOUT THESE ISSUES AND PEOPLE COMING OUT OF HUNDREDS OF DOLLARS TO FIX IT. CHEVY NEEDS TO DO A RECALL ON THIS ISSUES SOONER THAN LATER, THIS COULD BE BETWEEN LIFE AND DEATH FOR SOMEONE.

I HAVE A CHEVY MALIBU 2018 AND I COMMUTE TO WORK 5 DAYS A WEEK 1 1/2 HOURS EACH WAY. DURING MY COMMUTE WITHOUT WARNING, A LIGHT CAME ON INDICATING "ENGINE POWER IS REDUCED", THE ENGINE LIGHT, AS WELL AS THE CAR SLIPPERY ROAD SIGN. I HAVE AN APPOINTMENT AT MEARLE STONE CHEVROLET IN HOPES THIS KNOWN PROBLEM IN THE 2018 MODELS GETS FIXED WITHOUT PAYING OUT OF POCKET EXPENSES SINCE THERE HAS BEEN A MAJOR SAFETY CONCERN ON THE HIGHWAYS NOT BEING ABLE TO ACCELERATE LIKE NORMAL AND HAVING TO BUILD UP SPEED BY TAKING FOOT OFF ACCELERATOR. I CANNOT PASS DUE TO THIS AND THE ENGINE IS WINDING OUT LIKE I NEED TO CHANGE GEARS WHILE THE RPMS ARE GOING UP. I CANNOT GET PAST 60MPH EVEN WITH ACCELERATOR ALL THE WAY DOWN. I AM CONCERNED WITH THIS MODEL BEING MADE IN APRIL OF 2018, AND THE CHEVY MALIBU CLASS ACTION LAW SUITE ON "ENGINE POWER BEING REDUCED". THIS CAN BE VERY DANGEROUS KNOWING IT CAN GET WORSE IF THE DEALER DOES NOT FIX THIS. I HAVE ONLY HAD MY CAR BARELY COMING UP FOR A YEAR. I NEED TO HAVE A RELIABLE AND SAFE CAR THAT I DON'T NEED TO WORRY IF THIS WILL HAPPEN AGAIN.

WHILE DRIVING, THE MESSAGE 'ENGINE POWER IS REDUCED' APPEARED. MY CAR SLOWED DOWN AND I HAD TO PRESS REALLY HARD ON THE GAS PEDAL TO GET BACK UP TO THE SPEED I WAS AT. IT IS SAID TO BE A DEFECTIVE ELECTRONIC THROTTLE CONTROL AND ACCELERATOR PEDAL POSITION SENSOR. THIS PROBLEM IS COMMON IN MANY OF THE 2016-2018 CHEVY MALIBU'S. *BF

2018 CHEVROLET MALIBU WITH 15, 300 MILES. SINCE THE LAST RECALL WORK WAS COMPLETED, WHILE DRIVING ON THE HIGHWAY AROUND 65 MPH, THE STEERING WHEEL HAD AN INCREASE OF TENSION THEN IT SUDDENLY RELEASES ALL TENSION WHICH COULD POTENTIALLY LEAD TO A RAPID OVER CORRECTION. THE PROBLEM FEELS SIMILAR TO A MAGNETIC BREAK RELEASE. NO FAULT CODES TRIP AND THE DEALERSHIP SERVICE CENTER SAYS THEY CAN'T DUPLICATE ON WHILE STATIONARY OR SHORT DRIVES BUT IT'S FELT ON LONGER DRIVES GREATER THAN 15 MIN. PROBLEM HAS REMAINED FOR APPROXIMATELY A MONTH.

I WAS DRIVING DOWN THE INTERSTATE DOING 74 MILES AN HOUR WHEN ALL OF A SUDDEN THE CAR JERKED AND STARTED SLOWING DOWN. THE DISPLAY SCREEN SHOWED A MESSAGING SAYING ENGINE POWER REDUCED. I PULLED OVER ON THE SHOULDER BECAUSE IT WOULDN'T LET ME ACCELERATE AND HAD SLOWED THE CAR DOWN TO 50 MPH. I SAT THERE FOR A MINUTE AND WAS GOING TO TRY TO DRIVE ON THE SHOULDER TO THE NEXT EXIT. WHEN I STARTED THE CAR THE MESSAGE WAS NO LONGER THERE BUT THE CHECK ENGINE LIGHT WAS STILL ON. THE CAR HAS DONE THIS MORE THAN 10 TIMES SINCE THIS DAY.
