DRIVING AT 65 MPH, CAR FLASHED WARNING OF "DECREASING ENGINE POWER." CAR BEGAN TO SLOW TO A SPEED OF BETWEEN 20-30 MPH.

CHECK ENGINE LIGHT COMES UP AND THEN SAYS ENGINE POWER REDUCED. CANNOT ACCELERATE AT THAT TIME. IT HAPPENS WHEN I AM ON THE INTERSTATE AND SPEED REDUCES UNSAFELY. I HAVE TO FIND A PLACE TO PULL OVER AND TURN CAR OFF AND RESTART. THIS HAS HAPPENED MULTIPLE TIMES.

NHTSA ODI 11315943

THE CAR WAS DRIVING AT A HIGH SPEED AND THEN SUDDENLY SLOWED DOWN DRAMATICALLY. AN ERROR CODE, ALONG WITH THE CHECK ENGINE LIGHT, CAME ON STARTING REDUCED ENGINE SPEED. THE CAR IS NOT ABLE TO SPEED UP AT ALL. THIS HAS HAPPENED SEVERAL TIMES. WHILE DRIVING ON THE FREEWAY, WHICH IS VERY DANGEROUS.

NHTSA ODI 11312003

WHILE DRIVING ON THE FREEWAY OR THE STREETS THE VEHICLE LOOSES POWER. A DASHBOARD LIGHT COMES ON ALONG WITH THE CHECK ENGINE LIGHT AND THE DASHBOARD SAYS ENGINE POWER IS REDUCED. THIS CAUSES THE CAR TO DROP SPEED AND LOSE POWER. IT REALLY UNSAFE AS TWICE I'VE ALMOST BEEN REAR ENDED.

13 MONTHS AGO I BEGAN HAVING ACCELERATOR SENSOR ISSUES. DRIVING 40+ MPH AND THE CHECK ENGINE LIGHT CAME ON, "ENGINE REDUCED POWER", "STABILITRAK" CAME ON MY HUD. MY FATHER HAS A 2017 MALIBU AND THIS HAD JUST HAPPENED TO HIM, SO I KNEW TO PULL TO THE SIDE OF THE ROAD, SHUT THE CAR OFF AND TURN IT BACK ON, BUT THE LIGHT STAYED ON AND THE CAR WOULDN'T ACCELERATE PAST 40MPH AND TOOK FOREVER TO GET UP TO SPEED. TOOK IT IN AND THEY "FIXED" IT. I HAD TO HAVE IT FIXED 3 TIMES IN 3 MONTHS. ALL SIMILAR SITUATIONS, DRIVING 45+ MPH. MY TOUCH SCREEN RADIO ALSO WENT OUT, AND HAD TO GET A NEW HEAD UNIT. STILL TO THIS DAY ONLY ONE OF THE USB SLOTS WORKS. SUMMER GOES ON, NO ISSUES. OCTOBER TIME FRAME, MY CAR SHUT OFF WHILE I WAS DRIVING 60 MPH FOR A SPLIT SECOND. HEADLIGHTS WENT OUT, RADIO, SPEEDOMETER, ALL OF IT AT 5AM. IT CAME BACK ON WITHIN 2 SECONDS AND THE CAR WAS FINE. NO CHECK ENGINE LIGHT OR ANYTHING. HAD A BUDDY OF MINE RUN A CODE CHECK AND NOTHING SHOWED UP. A MONTH LATER I HAD ANOTHER ACCELERATOR SENSOR ISSUE, DRIVING 60+ MPH. HAD TO DRIVE ON THE SHOULDER OF THE ROAD UNTIL I COULD GET IT TO THE DEALERSHIP. TOOK IT IN AND GOT IT FIXED FOR FREE SINCE THERE WAS A RECALL. 2 MONTHS GO BY, WE'RE IN JANUARY 2020 NOW, DRIVING 60+ AND MY CAR SHOWS "STABILITRAK" AND HAD THE SAME SYMPTOMS OF THE PREVIOUS LOW POWER, AND NOT ACCELERATING. TURNS OUT TO BE THE AIR CHARGE COOLER. NOT A WEEK LATER AFTER GETTING IT BACK, DRIVING 70+ MPH AND MY CAR LOSES POWER. HAD TO TOW IT SINCE I WAS IN A DIFFERENT STATE. CYLINDER 1 HAS LOW PRESSURE AND THE CHARGE AIR COOLER IS FLOODED WITH DEBRIS. AND NOW CHEVY IS TELLING ME I HAVE TO PAY FOR A NEW ENGINE!! WTF?

INCIDENT HAS HAPPENED TWICE WHILE DRIVING ON HIGHWAY. ENGINE LIGHT CAME ON, THEN RECEIVED AN ERROR MESSAGE OF "ENGINE POWER REDUCED". ENGINE POWER AND ACCELERATION WAS REDUCED DRAMATICALLY. LUCKILY THERE WERE NO CARS BEHIND ME OR I MAY HAVE BEEN REAR ENDED AND INVOLVED IN AN ACCIDENT. I PULLED OFF ON SHOULDER AND TURNED CAR OFF AND THEN TURNED CAR BACK ON AND ENGINE POWER AND ACCELERATION WAS RESTORED. ENGINE LIGHT REMAINED ON THOUGH.

I WAS DRIVING ON THE HIGHWAY, SPEED LIMIT WAS 70MPH I WAS GOING THAT SPEED THEN OUT OF NOWHERE I GOT THE CHECK ENGINE LIGHT AND A NOTICE ON MY DASH APPEARED AS 'ENGINE POWER REDUCED' AND MY SPEED DRASTICALLY DECLINED I WAS ALMOST REAR ENDED BY A SEMI TRUCK, I HAD PEOPLE IN THE BACK OF MY CAR AND WITH AN IMPACT FROM A TRAILER WE COULD HAVE BEEN SERIOUSLY HURT OR EVEN KILLED. THIS A REOCCURRING PROBLE WITH MALIBU'S FROM THE YEAR 2016-2019 GM KNOWS ABOUT THE ISSUE BUT HAS DONE NOTHING TO RESOLVE IT. THIS ISSUE NOT ONLY PUTS THE DRIVER OF THE VEHICLE IN HARM BUT OTHERS AROUND AS WELL. THE PROBLEM IS THE THROTTLE BODY RESPONSE SENSOR WHICH IS ABOUT A $300-$500 FIX WHICH IS NOT AN CHEAP FIX. THEY NEED TO BE HELD RESPONSIBLE FOR THIS BECAUSE ONE DAY THIS COULD HAPPEN TO ANYBODY WITH THIS TYPE OF CAR AND IT CAN KILL SOMEONE.

MY 2016 CHEVY MALIBU COMPLETELY LOST POWER TWICE ON 2/6/2020. THE ENGINE SHUT COMPLETELY DOWN. THE FIRST INCIDENT HAPPENED WHILE WAITING IN THE PICK UP LINE AT MY DAUGHTERS SCHOOL WHICH IS IN A PARKING LOT FULL OF KIDS. THE CAR JUST SHUT COMPLETELY DOWN WHILE IN DRIVE. IT ACTUALLY DIED. NO INSTRUMENT PANEL ON, NO RADIO ON, NO HEAT. I HAD TO PUT THE CAR IN PARK AND THEN PUSH THE PEDAL ALONG WITH THE PUSH TO START BUTTON TO RESTART THE CAR. THE SECOND INCIDENT HAPPENED ABOUT 15 TO 20 MINUTES LATER WHILE I WAS STOPPED AT A TRAFFIC LIGHT. ONCE AGAIN THE CAR WAS IN DRIVE AND JUST COMPLETELY SHUT DOWN. THE SAME THING HAPPENED AS THE FIRST INCIDENT BUT THIS TIME I AM IN HEAVY TRAFFIC DURING THE TIME WHEN KID'S ARE RELEASED FROM SCHOOL AND PEOPLE IN GENERAL ARE MOVING AROUND THE CITY. ALL OF THIS HAPPENED DURING A HEAVY SNOW HERE IN MY STATE. FOR A PERSON DRIVING UP BEHIND ME I'M SITTING THERE WITH NO LIGHTS ON AT A NOW GREEN TRAFFIC LIGHT IN UNSAFE WEATHER CONDITIONS. VEHICLES WERE BLOWING AND GOING AROUND US TO AVOID AN ACCIDENT. I HAD TO ACT FAST FOR OUR SAFETY ALONG WITH THE OTHER DRIVERS ON THE ROAD. MY DAUGHTER AND MYSELF WERE SCARED OF BEING IN AN ACCIDENT. I HAVE AN APPOINTMENT TOMORROW 2/7/2020 AT A GENERAL MOTORS DEALERSHIP TO LOOK INTO THE PROBLEM.

WHILE DRIVING TO MY JOB AND I PRESSED ON THE PEDAL BRAKE, IT FELT LIKE THE BRAKES WAS HAVING TROUBLE TO BRAKE SO I HAD TO BRAKE HARD AND DRIVE CAREFULLY. IT WOULD MAKE A SOUND WHEN I WOULD PRESS DOWN ON THE PEDAL. TOOK IT TO A MECHANIC AND HE TOLD ME THAT THE ABS IS BROKEN AND THAT'S WHAT GIVING ME A HARD TIME TO BRAKE. HE CHECKED ALL OF MY BRAKES ARE STILL GOOD AND NOTHING WRONG WITH THEM.

ENGINE REDUCED LIGHT

WHEN STOPPING THE VEHICLE THE SHIFTER CONTROL MODULE DOES NOT RECOGNIZE WHEN THE VEHICLE IS IN THE PARK POSITION. WHEN THIS HAPPENS THE VEHICLE DISPLAY'S A MESSAGE AND A WARNING BELL SOUNDS WHEN YOU OPEN THE CAR DOOR. THE INTERIOR LIGHTS, DASH AND RADIO OF THE VEHICLE WILL NOT TURN OFF UNTIL THE VEHICLE BELIEVES IT'S PROPERLY PUT INTO PARK. NO ERROR CODE IS STORED IN THE CARS MEMORY. GM HAS A FIX FOR THIS BUT THE PROBLEM KEEPS RECURRING. MY VEHICLE'S SHIFTER MODULE WAS REPLACE UNDER THE ORIGINAL WARRANTY. THAT FIX FAILED 2 YEARS LATER. THE MOST RECENT FIX WAS TO REPLACE A HARNESS IN THE SHIFTER MODULE. THE DEALER WOULD NOT FIX THIS UNDER THE EXISTING CPO WARRANTY EVEN THOUGH IT WAS A RECURRING ISSUE AND THERE HAVE BEEN MULTIPLE SERVICE BULLETINS CONCERNING THIS ISSUE AND ORIGINALLY REPAIRED UNDER THE ORIGINAL WARRANTY. THIS MOST RECENT FIX HAS FAILED AGAIN AFTER 6 WEEKS OF BEING REPLACED. IF THE VEHICLE DOES NOT RECOGNIZE WHAT GEAR IT IS IN I BELIEVE THIS COULD BE A SAFETY ISSUE. AS IT IS WHEN THE VEHICLE DOES NOT RECOGNIZE THAT THE VEHICLE (SHIFTER MODULE) IS IN THE PARK POSITION THE VEHICLE STAYS ACTIVE AND DRAINS THE BATTERY UNTIL THE ERROR IS CORRECTED. YOU ALSO CANNOT LOCK THE VEHICLE. THE CAR HAS TO BE RESTARTED AND MOVED AND IF YOU ARE LUCKY WHEN THE VEHICLE IS SHUT DOWN IT WILL FINALLY RECOGNIZE THAT THE VEHICLE IS IN PARK. AS THIS HAPPENS INTERMITTENTLY IF THE VEHICLE IS TAKEN TO THE DEALERSHIP THEY WILL NOT ADDRESS THE ISSUE IF THEY DO NOT SEE THE ERROR MESSAGE ON THE VEHICLES DRIVER INFORMATION SCREEN WHEN THE VEHICLE IS BROUGHT IN FOR SERVICE.

AFTER PUTTING MY CAR IN PARK I GET A WARNING THAT THE CAR IS NOT IN PARK. WHEN THIS HAPPENS THE CAR WILL NOT LOCK PLUS THE LIGHTS AND THE RADIO WILL NOT TURN OFF. MY CONCERN IS THAT THE CAR IS REALLY NOT IN PARK PLUS MY SECURITY WITH THE DOORS NOT LOCKING. HAVE HAD IT TO THE DEALER TWICE NOW THEY WANT ME TO REPLACE THE SHIFTER ASSEMBLY AT MY COST SINCE IT IS OVER 3 YRS OLD BUT STILL UNDER 30,000 MILES.

THE EARLIEST DEALERSHIP APPOINTMENT WAS FOR 1/20/20 IN A CITY APPROXIMATELY 30 MINUTES AWAY; I CALLED THE CHEVROLET WARRANTY LINE AND WAS ADVISED TO TRY CALLING OTHER DEALERSHIPS AND TAKE MY VEHICLE TO BE SERVICED THERE, DESPITE MY REPEATED EXPLANATIONS OF THE SAFETY RISK DUE TO THE ENGINE FAILURE.

ON JAN 6 2020. I WAS DRIVING A 2016 CHEVY MALIBU, WHEN THE CHECK ENGINE LIGHT AND ENGINE REDUCE POWER LIGHT CAME ON. I PULLED OVER AND LET THE CAR SEAT FOR MAYBE 10 MINS. I RESTARTED THE VEHICLE AND BEGIN DRIVING AGAIN (IT WAS PULLING NORMAL). ABOUT 3 MILES DOWN THE ROAD I WAS MAKING A LEFT TURN AND THE CAR STOP PULLING AND THE REDUCE ENGINE POWER LIGHT COMES ON WHICH LEAVES ME IN THE MIDDLE OF A INTERSECTION SECTION CAUSING A VEHICLE COMING FROM MY RIGHT SIDE TO SLAM INTO THE SIDE OF VEHICLE DEPLOYING ALL OF MY AIRBAGS AND MAKING ON-STAR ASSISTANCE COME ON. IN THE RESULT I HAVE NECK, BACK AND SIDE INJURY FROM THE IMPACT. WHICH IN THE RESULT I'M GETTING SUED BECAUSE MY CAR STALLED IN THE MIDDLE OF THE TURN GOING LEFT. MY CAR WAS TOTALED OUT AND MY INSURANCE DON'T WANT TO PAY THE FULL VALUE OF WHAT I WAS LEASING IT FOR. WHICH I HAVE TO COME OUT THE POCKET WITH EXPENSES. AFTER REVIEWING THE "ENGINE REDUCE POWER" AND DOING MY RESEARCH I COME TO FIND OUT IT HAS BEEN NUMEROUS COMPLAINTS. I COULD HAVE LOST MY LIFE!
