What 786 owners told NHTSA about the 2016 Chevrolet Impala Eco Eassist

WHILE DRIVING AT A HIGH RATE OF SPEED, MY ENGINE REDUCED LIGHT CAME ON AND WOULD NOT ALLOW ME TO DRIVE OVER 32 MPH. THIS COULD HAVE CAUSED AN ACCIDENT WITH SEVERE INJURY CONSIDERING WHERE I WAS DRIVING. I HAVE SEEN MANY OTHERS COMPLAIN ABOUT THIS, WHY HASN'T IT BEEN RECALLED, WHEN WILL IT BE RECALLED?

AS I WAS DRIVING AT A HIGH SPEED MY ENGINE POWER REDUCED LIGHT CAME ON AND MY CAR SPEED SLOWED DOWN DRASTICALLY. WHEN DIAGNOSED IT SAID IT WAS THE ACCELERATOR POSITION PEDAL. THIS IS VERY UNSAFE AND ALMOST CAUSED A WRECK. FROM WHAT I HEAR THIS IS COMMON WITH THE MABILU AND NEEDS TO BE RECALLED SEEING THAT SOMEONE COULD LOSE THEIR LIFE.

CAR SHOWED A "REDUCED ENGINE POWER" NOTIFICATION AND COULD NOT ACCELERATE OVER 15 MPH.

WHEN I'M DRIVING I GET A MESSAGE SAYING 'ENGINE REDUCE POWER' AND I CAN'T GO OVER 25 MPH

BACK IN DECEMBER OF 2020, EVERY TIME I STOPPED AT A RED LIGHT OR BRAKE (WHEN COMING TO A STOP IN TRAFFIC) THE CAR COMPLETELY SHUTS OFF. I WOULD GET A WARNING THAT THE CAR WAS IN BATTERY SAVE MODE AND THE STABILITRAK LIGHT WOULD COME ON. THE MORNING OF JAN. 12, 2021, IT HAPPENED WHILE DRIVING ON THE INTERSTATE 322. I BLOCKED RUSH HOUR TRAFFIC FOR ABOUT 20 MINUTES BEFORE THE CAR STARTED BACK UP. WHILE THIS WAS HAPPING NOTHING ON THE CAR WORKED. IT BLOW OUT COOL AIR AND THE RADIO AND WINDOWS DIDN'T WORK. THIS IS A BIG PROBLEM AND IS VERY DANGEROUS. NOT JUST FOR ME AND MY FAMILY BUT OTHER DRIVERS ON THE ROAD. I DID TAKE THE CAR TO BE SERVICED UNFORTUNATELY, THEY COULD NOT FIND ANYTHING WRONG WITH THE CAR. INSTEAD OF RESTING ON THE BREAK IN TRAFFIC, WE PUT THE CAR IN PARK. YOU CAN SEE HOW THAT CAN BE PROBLEMATIC. IN ADDITION TO THAT, NOW IT SOUND LIKE SOME SORT OF LIQUID IS PASSING THROUGH WHEN I COME TO A STOP/PARK. FAST FORWARD TO WHAT HAS LEAD ME TO FILING A VEHICLE SAFETY COMPLAINT, THIS EVENING MY SON WAS DRIVING ON US 22 WHEN HE CALLED ME IN A PANIC BECAUSE WHILE DRIVING A WARNING DISPLAYED ON THE DASH ENGIN POWER REDUCED, TRACTION LIGHT AND ENGINE LIGHT CAME ON SIMULTANEOUSLY. THE SPEED REDUCED TO ABOUT 20 AND WOULD NOT ACCELERATE. I TOLD HIM TO PUT ON THE HAZARD LIGHTS AND PULL OVER02 AS SOON AS IT WAS SAFE. HE DID AS I SAID AS I WAITED ON THE PHONE WITH HIM. HE TURNED THE CAR OFF AND LET IT REST FOR ABOUT 5 MINUTES. THE CAR STARTED BACK UP WITHOUT ANY PROBLEMS. THE TRACTION LIGHT WENT OFF BUT THE CHECK ENGINE LIGHT IS STILL ON. HE MADE IT HOME WITHOUT ANY MORE INCIDENTS. AS I STATED ABOVE YOU CAN SEE HOW THIS IS A SERIOUS PROBLEM. I AM LEARNING THAT I AM NOT THE ONLY ONE WITH A CHEVY MALIBU (2016 64,763 MILES) WITH SAFETY ISSUES. THIS IS UNACCEPTABLE. I HOPE THAT NO ONE HAS TO LOSE THEIR LIFE BEFORE ACTION IS TAKING. THEY NEED TO RECALL AND GIVE A REFUND.

AS I WAS EXITING THE HIGHWAY THE JUST SLOWED TO A CRAWL . THE SCREEN SAID REDUCED ENGINE POWER AND WOULDN'T ALLOW ME TO ACCELERATE PAST 15 - 20 MILES PER HOUR. LUCKILY THERE WERE NO CARS FOLLOWING BEHIND ME AT THE TIME . I PULLED OVER SHUT THE CAR OFF AND ISSUE CONTINUED. I PLUGGED UP A CODE READER AND GOT P2138

MY ENGINE LIGHT COMES ON AND 'ENGINE POWER REDUCED ' APPEARS ON THE DASHBOARD. THE CAR'S SPEED DROPS & I CAN ONLY DRIVE AT 20-25 MPH. I RESTART THE CAR AND IT DRIVES FINE FOR 2MINS AND THEN GOES INTO LIMP MODE. IT'S A DANGEROUS SITUATION B/C I'M ON THE HIGHWAY DOING 60-65 AND THIS HAPPENS. I'M THANKFUL I DIDN'T GET INTO AN ACCIDENT. CODE P2138 IS WHAT MAKES THE ENGINE LIGHT COME ON. THROTTLE/PEDAL ACCELERATOR .

I NOTICED AN OIL LEAK IN MY GARAGE AND DRIVE WAY FROM MY VEHICLE WHICH IS AN ENVIRONMENTAL AND SAFETY HAZARD. I HAVE TAKEN THE VEHICLE TO THE MANUFACTURER'S DEALERSHIP AND AN INDEPENDENT SHOP AND THEIR CONCLUSION FOR THE CAUSE OF THE OIL LEAK IS FROM A HEAD GASKET AND UPPER OIL PAN GASKET LEAK. THIS VEHICLE IS 4.5 YEARS OLD AND HAS 78,000 MILES ON THE VEHICLE AND SHOULD HAVE NOT PRESENTED AN ISSUE LIKE THIS EARLY IN ITS LIFE EXPECTANCY. THE LEAKING HEAD AND UPPER OIL PAN GASKETS CAUSES ENVIRONMENTAL CONCERNS OF OIL NOT BEING DISPOSED OF PROPERLY THAT COULD AFFECT OUR WILDLIFE AND FOOD SUPPLY. THE SAFETY CONCERN IS THAT THERE ARE NO OTHER SIGNS OF THIS FAILURE THUS IT IS A SAFETY HAZARD FOR THE OCCUPANTS OF THE VEHICLE AND COMMUTERS ALONG SIDE THE VEHICLE.

DRIVING 65MPH ON HIGHWAY CHECK ENGINE LIGHT AND STABILATRACK LIGHTS FLASH AND LOSS OF POWER STARTS HAPPENING AND CAR WONT GO OVER 20MPH ... CHEVY CLAIMS ITS NORMAL AND DONT FIND A.REASON WHY IT HAPPENED. IVE HAD THE CAR AT CHEVY 6 TIMES FOR ISSUE AFTER ISSUE AND NOW THIS LOSS OF POWER ON A HIGHWAY NEARLY KILLED ME AS I COULD BARELY GET CAR TO A.SAFE LOCATION...

THERE NEEDS TO BE A RECALL ON THE BRAKE BOOSTER SYSTEM. I HAVE HAD THIS REPLACED ONCE ALREADY. IT IS VERY DANGEROUS! THE ENGINE LIGHT COMES ON AND WHEN U PRESS THE BRAKE THERE IS A LOUD GUSH OF AIR AND IT'S HARD TO STOP.

16' CHEVY MALIBU, 170K MILES. REAR POPPING NOISE, BACK LEFT. HEARD A POP NOISE FROM BACK LEFT OF CAR AFTER LETTING OFF THE BRAKES FROM A STOPPED POSITION. TOOK THE LEFT REAR (LR) TIRE OFF AND FOUND LR BRAKE CALIPER PISTON TO HAVE FAILED AND WOULD NOT RESEED INTO CALIPER CAUSING POPPING NOISE. TOOK CAR TO PORTER CHEVROLET IN NEWARK, DE ON 1/20/21 FOR CALIPER REPLACEMENT AND THEY INFORMED ME THAT THE PART WAS ON NATIONAL BACK ORDER DUE TO MANY CARS BEING AFFECTED BY THE SAME ISSUE. I HAD PART ORDERED AND PICKED UP MY CAR UNTIL THE CALIPER COMES IN. WILL BRING CAR BACK TO PORTER WHEN PART COMES IN FOR REPLACEMENT AND HOPEFULLY RECALL CREDIT IN NEAR FUTURE. DO NOT LET DEALERSHIPS/ REPAIR SHOPS TELL YOU THAT IT IS THE REAR SHOCK! IT IS THE BRAKE CALIPER THAT IS MAKING THE POPPING NOISE.

DRIVING ON THE EXPRESSWAY WHEN MY CAR GOT A MESSAGE ON THE DASH SAYING 'REDUCED ENGINE SPEED' . I WENT FROM 60MPH TO 10MPS WITHIN SECONDS, THIS IS A SERIOUS LIFE THREATENING PROBLEM WHEN DRIVING. ONCE IT SLOWS COMPLETELY DOWN IT STOPS AND I HAVE TO TURN OFF MY CAR AND RESTART IT JUST FOR IT KEEP HAPPENING. WHEN I TOOK MY CAR TO A CHEVY DEALERSHIP THEY TOLD ME 'EVERYONE WITH A MALIBU IS HAVING THESE PROBLEM LAST AND THEY CAN NO FIX IT CAUSE THE CAN'T FIGURE OUT THE PROBLEM. THEY ALSO INFORMED ME WITH ALL THE MALIBU'S HAVING THE SAME EXACT PROBLEM IS SHOULD BE A RECALL. I WENT TO A ANOTHER CHEVY DEALERSHIP AND WAS TOLD THE EXACT SAME THING. CHEVY WANT US TO ENJOY THE CAR BUT WILL NOT GO THE EXTRA MILE TO DO RECALLS ON THEM WHEN THEY KNOW IT'S A BIG PROBLEM. MY CAR ALSO BE STUCK IN 'SHIFT TO PARK' WHEN IT'S ALREADY IN PARK, I HAVE TO CONSTANTLY RESTART MY CAR AND TURN IT OFF FOR THE MESSAGE TO GO ALWAYS AND MY CAR IS OFF, WHICH IS RIDICULOUS BECAUSE IF YOU LEAVE YOUR CAR IN SHIFT TO PARK THAT WILL COMPLETELY KILL YOUR BATTERY. ALSO, WHEN I START MY CAR IT SOUND LIKE A BUNCH OF WATER JUST MOVING AROUND BUT IT'S NOTHING LEAKING BUT YOU CAN HEAR THE WATER ONCE YOU START THE CAR. THE BRAKES ON THE CAR DO NOT LAST LONG ENOUGH! I WENT TO GET SOME BRAND NEW BRAKES IN OCTOBER AND WAS TOLD FROM TWO DIFFERENT CAR SHOPS THAT I NEED NEW BRAKES . THESE PROBLEMS IS RIDICULOUS AND DANGEROUS AND COULD BE FIXED BY RECALLING THE CARS AND FIXING THE PROBLEMS .

ENGINE LIGHT CAME ON AND VEHICLE DISPLAYED " REDUCED ENGINE POWER". VEHICLE LOST ACCELERATION AND I HAD TO PULL TO THE SIDE OF THE ROAD. AFTER TURNING OFF VEHICLE, WAITING A MINUTE, AND RESTARTING VEHICLE IT RAN OK FOR 5 MINUTES. SOMETIMES IT RUNS LONGER BEFORE THE LIGHT COMES BACK ON AND I LOSE POWER AGAIN. THIS IS DANGEROUS!!!

WAS DRIVING ON HIGHWAY AT 60 MPH AND DASHBOARD LIT UP WITH WARNING ENGINE POWER REDUCED MODE AND CAR WENT INTO LOW SPEED. TRIED ACCELERATING CAR WOULD NOT GO BEYOND 20 MPH

SEVERAL TIMES A WEEK MY CAR WILL SUDDENLY GO INTO "ENGINE POWER REDUCED" MODE AND GO INTO LOW SPEED. IF I GET OUT OF THE CAR, LOCK IT, AND UNLOCK IT 30 SECONDS LATER IT WILL RESET AND THEN BE OKAY FOR A FEW MINUTES. THIS POWER REDUCTION IS EXCEEDINGLY DANGEROUS WHEN MOVING AT HIGHWAY SPEEDS AND SUDDENLY NEEDING TO PULL OVER. THE CHECK ENGINE LIGHT WILL COME ON BUT THEN DISAPPEAR SOMETIMES THE SAME DAY AFTER HAVING PARKED FOR A WHILE. TYPICALLY THE CAR GOES INTO THIS "REDUCED POWER MODE" AFTER ABOUT 45 MINUTES OF DRIVING. I WAS ABLE TO CAPTURE THE FOLLOWING ERROR CODES: P1101 (INTAKE AIR FLOW SYSTEM PERFORMANCE), P2122 (THROTTLE POSITION SENSOR D CIRCUIT LOW INPUT), AND P2138 (THROTTLE/PEDAL POSITION SENSOR/SWITCH D/E VOLTAGE CORRELATION). REALLY HOPING THIS WILL BE REPLACED UNDER WARRANTY INSTEAD OF HAVING TO GET IT FIXED MYSELF!

I WAS DRIVING ONE DAY AND ALL OF A SUDDEN, I HAVE SEEN 'ENGINE POWER REDUCED' WARNING ON THE DASHBOARD. THIS WARNING REDUCES THE CAR SPEED CONSIDERABLY AND THEREFORE SLOW THE CAR NO MATTER HOW FAST YOU ARE GOING. I TOOK THE CAR TO A CHEVY DEALERSHIP TO GET IT CHECKED AND THEY TOLD ME THAT ONE OF MY INTAKE VALVE WAS DEFECTIVE. I HAD IT REPLACED AND PAID FOR THE SERVICE. I LEFT AND THE SAME DAY THE WARNING CAME BACK AGAIN AND SLOWED THE CAR. THE SPEED CAN GO FROM 60MPH TO LESS THAN 10MPH IN FEW SECONDS. STEPPING ON THE ACCELERATOR PEDAL AGAIN DOESN'T HELP THE CAR INCREASE SPEED. I HAVE RESEARCHED ONLINE AND MANY OTHER DRIVERS HAVE SIMILAR ISSUES. I TOOK THE CAR BACK TO THE DEALERSHIP TO HAVE THEM DIAGNOSED IT AGAIN. UNFORTUNATELY THEY HAVE NOT DETECTED THE CAUSE OF THE WARNING 'ENGINE POWER IS REDUCED'. THEY TOLD ME THEY DON'T KNOW WHAT TO DO AND ARE ASKING ME TO REPLACE MY ENGINE. I THINK THIS IS ABSOLUTELY RIDICULOUS.

MY VEHICLE HAS A LOUD KNOCKING SOUND COMING FROM UNDER THE BACKSEAT SOUNDS LIKE THE MUFFLER HITTING UP AGAINST THE BACKSEAT. WE AS CONSUMERS SHOULDN'T BE RESPONSIBLE FOR SOMETHING THAT WAS CHEVROLET FAULT FROM THE START

WHEN AUTO-STOPPED THE ENTIRE CAR SHUTS DOWN. IT TURNS COMPLETELY OFF AND STARTS MOVING BACKWARDS BEFORE TURNING BACK ON. A DIAGNOSTIC REVEALED A PROBLEM WITH THE POWER SUPPLY TRANSFORMER AND BATTERY CURRENT SENSOR CIRCUIT. THEY ARE ERODED I BELIEVE. THIS PROBLEM OCCURS ANYTIME THE BRAKES ARE APPLIED - AT STOP SIGNS AND LIGHTS.

ENGINE POWER REDUCED, THIS HAS HAPPENED COUNTLESS TIMES, SINCE THE VEHICLE WAS PURCHASED IN JANUARY 2017, IT HAS BEEN TO BRYNER CHEVROLET IN JENKINTOWN, PA, WHERE IT WAS ORIGINALLY PURCHASED MORE TIMES, THAN I CAN COUNT. EACH REPAIT COSTING MORE AND MORE. I'M ASSUMING CHEVY IS WAITING FOR SOMEONE TO DIE, BEFORE THEY ACTUALLY FIX IT. IMAGINE BEING ON A MAJOR HIGHWAY AND GOING FROM DOING 65 TO 20 UNEXPECTEDLY. THE PERSON BEHIND ME HAD TO SWERVE INTO ANOTHER LANE TO KEEP FROM REAR ENDING ME.

I JUST EXPERIENCED THE CHECK ENGINE LIGHT ON AND REDUCED POWER ALERT ON CHRISTMAS EVE: 12/24/20 THIS WAS SO SCARY ON HIGHWAY AND HAD TO DRIVE ON THE REDUCED POWER WITH MY FLASHERS ON AND TERRIFIED AS CAR'S WIZZED PAST ME! I WAS WORRIED THAT I WOULD BREAKDOWN AND COULDN'T GET HOME. I DID MAKE IT HOME AND WAS SHAKEN BY THE EXPERIENCE. I HAVE A 2016 CHEVY MALIBU AND THE DEALERSHIP QUOTED $350 TO FIX IT. IT IS STILL THERE AS DIDN'T HAVE FUNDS TO FIX IT. DEALERSHIP SAID IT IS AN ISSUE WITH GAS PEDAL NOT READING IN SYSTEM CORRECTLY. THIS IS A HUGE SAFETY RISK BECAUSE IT HAPPENED WHILE DRIVING ON HIGHWAY GOING 60 MPH, AND IT DROPPED SPEED TO 35 MPH! THIS IS SO DANGEROUS! ESPECIALLY BECAUSE IT HAPPENED AT NIGHT IN A SECLUDED AREA. THIS IS SUPER SCARY FOR A WOMAN DRIVER THINKING I WAS GOING TO BREAKDOWN AT ANY MOMENT. I HAVE BEEN DRIVING UBER SINCE COVID AND NO WORK AVAILABLE IN MY REGULAR JOB. SINCE I DON'T HAVE MY CAR, I CAN'T DRIVE TO MAKE ANY MONEY TO FIX IT. I WAS UNABLE TO WORK ON UBER'S BIGGEST NIGHT OF THE YEAR ON NEW YEAR'S EVE, LOSING OUT OF A $500 NIGHT. GM SHOULD PAY TO GET THIS FIXED AND FOR LOST REVENUE DUE TO UNABLE TO WORK.

WHEN THE CAR GOES INTO THE AUTO STOP MODE IT COMPLETELY DIES AND THE LIGHT. NO DASH LIGHTS, NO DOME LIGHT, NO HAZARD LIGHTS, LITERALLY NOTHING WORKS. THIS HAS HAPPENED 3 TIMES SO FAR, AND ALL THREE TIMES I WAS IN THE MIDDLE OF TRAFFIC. I'M NOT HAPPY, I HAVE HAD TROUBLE OUT OF THIS CAR WITH OTHER ISSUES SENSE I GOTTEN IT BACK IN JULY OF 2020
