2014 Chevrolet Malibu Powertrain & Transmission Problems

Received vehicle at roughly 181,000 miles. Operated fine for about 5,000 miles and then began to show problems. In most cases when pressing down hard on the accelerator pedal, transmission drops into a lower gear and revs up to 5k rpm, cancelling cruise control, and staying there until accelerator is relieved. This makes accelerating more difficult since too much pressure on the accelerator pedal causes the car to get stuck at 5k rpm and stay at the same speed it is already at. This makes passing cars more dangerous as the car gets stuck at 5k rpm and can't pass the other vehicle, increasing the risk of a head on collision. Service engine and ABS lights are on as well as a service Stabilitrak notification in the driver information center. In addition, the outside temperature thermometer is faulty and shows much lower temperatures, such as -14 degrees during an 80 degree day. Vehicle is up to maintenance as far as my knowledge goes. Car has been previously junked twice and has a rebuilt title. There are no fluid leaks, the engine works well when the problem is not encountered, but it gets stuck at 5k rpm under hard acceleration more than it doesn't.

The contact owns a 2014 Chevrolet Malibu. The contact stated that while driving at various speeds, the lights on the gear shifter was flashing, with the power steering assist and parking assist messages displayed on the instrument panel. The contact stated that the vehicle jerked violently while depressing the accelerator pedal. The vehicle was taken to an independent mechanic where the vehicle was diagnosed with transmission failure. The vehicle was not repaired and remained with the dealer. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 130,000.

powertrain there is a problem with auto stop restarting then dying. The transmission not engaging after a complete stop like it is neutral this only happens after the car has been driven a bit everything at temp. today stopped for trash service auto stop engaged got ready to go nothing gunning and gunning never died like no power though finally moved no more stops till home a problem sitting in road can not move. have not taken to shop yet money for it now not.

The cars automatic start/stop will activate and not restart the car. This has happened at stop signs, stop lights, intersections, hard breaks, etc. There are no warning lights or system failed/malfunction warnings. This has been inspected multiple times with software updates, changing batteries, changing fuses, etc.

The contact owns a 2014 Chevrolet Malibu. The contact stated that while accelerating between 0 to 20 MPH, the transmission hesitated while shifting into first gear. While driving at speeds above 20 MPH the hesitation was more prominent, causing the vehicle almost stall; however, the vehicle would remain running. The contact stated that the “Transmission Failure” warning light was illuminated. The contact became aware of NHTSA Campaign Number: 14V092000 (Power Train). The dealer had not been contacted. The vehicle had not been diagnosed or repaired. The manufacturer was made aware of the failure and confirmed that the VIN was not included in NHTSA Campaign Number: 14V092000 (Power Train). The manufacturer had referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 93,000.

The Auto Stop/Start feature is experiencing issues where the vehicle fails to restart, resulting in significant disruptions during driving scenarios such as heavy city traffic, stop-and-go traffic, and maneuvering through busy intersections. These incidents not only cause traffic jams and congestion but also force detours for other drivers. Particularly, when encountering highway traffic from exit offramps, sudden stops due to overcrowding and tailgaters trigger the Malibu to auto stop without restarting, creating considerable challenges, especially during rush hours in cities like Atlanta. In each of these circumstances, attempts to restart the vehicle prove futile as the engine endlessly turns over without success. While resolving these situations required considerable effort and time, further elaboration is beyond the scope of this discussion, given the valuable time already expended on addressing these issues.

The automatic start and stop function does not work properly. When the car comes to a stop and auto stops, the vehicle shuts off and does not power up when you hit the gas. My safety is put at risk due to the car shutting off and the possibility of someone hitting me. The vehicle has been inspected countless times. I was told it was an electrical issue. Then told it was the battery. Brand new battery and issue isn’t fixed. The car cut off once and all the lights came on. Now no lights comes on it just cuts off.

P2646 diagnostic code - rocker arm control solenoid In June 2020, GM issued "Special Coverage Adjustment N192289160 Rocker Arm Oil Control Valve Inoperative" for the coverage of the repair for rocker arm oil control valve, (OCV) for 10 years after the purchase date, or 120,000 miles for the 2014 Malibu and Impala. However, our vehicle had the failure at 122,000 miles. The Special Coverage should be adjusted, or even transitioned to a full recall since the parameters of the initial bulletin are insufficient.

The contact owns a 2014 Chevrolet Malibu. The contact stated upon starting the vehicle, the check engine warning light was illuminated. The vehicle was taken to an unknown dealer where it was diagnosed that the failure was associated with the battery. However, the battery was not replaced. The contact stated while driving 35 MPH, the vehicle would not properly shift into gear, decelerated independently, and stopped. The contact was able to restart the vehicle however, upon moving the gear shifter into drive(D), the vehicle failed to respond. The contact then moved the gear shifter to park(P) however, the vehicle rolled away and struck a tree. The air bags did not deploy. There was no injury sustained. The vehicle was towed to the residence. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact was awaiting a call back from the manufacturer. The failure mileage was approximately 120,000.

The contact owns a 2014 Chevrolet Malibu. The contact stated that when she started the vehicle, the vehicle was in manual mode while the vehicle was parked. The vehicle failed to shift into gear as needed. An independent mechanic diagnosed the vehicle and replaced the battery; however, the failure persisted. The dealer was contacted, and the contact explained that her vehicle had experienced the failure listed in NHTSA Campaign Number: 14V092000 (Power Train). The dealer confirmed that the VIN was not included in the recall and informed her that she was responsible for the cost of the repair. The manufacturer was contacted, and they also stated that the vehicle was not under recall and advised to contact the NHTSA. The failure mileage was 214,000.

I have owned this car for a little over 3 years and it suddenly started giving me a "Shift to Park" message after I physically put the car in "Park" and turn the car off. The car will not turn off completely because the car does not think that it is in "Park". It is gradually getting worse as time goes on. There were two instances where I thought the car was turned off and when I came back to my vehicle, the car was dead. All within 15 minutes. The car does not shut off after turning it off because it thinks that the car is not in park so the radio, lights, and everything electrical stays on. This issue causes the battery to drain quickly. This issue can easily leave someone stranded with a dead car. I took it to the dealership to get a diagnostic test on it in June 2022 and they could not replicate the issue. I am taking it back again this month (August 2022). I have read a lot of discussion forums about this issue. There was only a recall for the same model for the production years of 2016-2019 I believe. This issue is pretty common among Chevrolet and I think that it's crazy that there is a huge problem with their shifter assembly and they never fixed it!

The vehicle will still be running after I turn the engine off and take the key out of ignition.

My car is throwing a rocker arm valve code but chevy is saying its not covered under the NHTSA program that was passed. Its a 2014 chevy malibu 2.5 L with 93000 miles on it. It causes the auto stop to malfunction and the car will completely shut down when stopped. It will not restart at all. Have been almost hit 3 times at major intersections.

SINCE WE PURCHASED 02/2016 CHEVY MALIBU THE ENGINE LIGHT HAS BEEN ON AND OFF AND THE DEALER HAS FIXED THE PROBLEM MANY TIMES AND STILL HAS THE SAME PROBLEM . I NOTICED THE GEAR IS WEAK SPECIALLY WHEN I'M ON THE FREEWAY

THIS HAS HAPPENED TWICE NOW, ONCE FOR MY WIFE AND THE SECOND TIME I WAS DRIVING. BOTH INCIDENTS HAPPENED WHILE IN MOTION ON THE HIGHWAY AND THE VEHICLE DISPLAY SHOWED REDUCED ENGINE POWER AND THE VEHICLE DE-RATED AND SLOWED AUTOMATICALLY ON THE HIGHWAY. THE CHECK ENGINE LIGHT DISPLAYED AND AFTER CONNECTING A CODE READER TO THE OBD AND CODE P2138 WAS LOGGED WHICH IS POTENTIALLY A FAULTY THROTTLE POSITION SENSOR/ FOOT GAS PEDAL. I REPLACED THE THROTTLE POSITION SENSOR CLEARED THE STORED CODE AND A COUPLE WEEKS LATER THE VEHICLE AGAIN WENT INTO LIMP MODE AND DE-RATED ON HIGHWAY. THE CHECK ENGINE LIGHT CAME ON AND THE SAME CODE P2138 WAS LOGGED INDICATING VOLTAGE DIFFERENCE BETWEEN APP SENSOR 1 AND APP SENSOR 2 OF THE THROTTLE POSITIONING SENSOR. AFTER FURTHER RESEARCH ON LINE I FOUND THAT A GM SERVICE BULLETIN WAS ISSUED FOR POTENTIAL MOISTURE INTRUSION OF THE CONNECTORS FROM THE THROTTLE POSITION SENSOR TO THE ECM. (SEE ATTACHED) IT SEEMS LIKE MY VEHICLE IS EXPERIENCING MOISTURE IN THE CONNECTORS AS BOTH INCIDENTS HAPPENED WITHIN MINUTES OF TAKING THE VEHICLE THROUGH AN AUTOMATIC CAR WASH. IN MY OPINION THIS IS A SAFETY CONCERN FOR THIS MODEL VEHICLE TO DE-RATE AND SLOW DOWN SUDDENLY AT HIGHWAY SPEEDS WITH CARS FOLLOWING BEHIND AND HAS BEEN A KNOWN ISSUE BY GM AND SHOULD HAVE A RECALL ISSUED.

DRIVING DOWN FREEWAY ABOUT 70 MPH WHEN ALL OF A SUDDEN I HEAR A CHIME THEN ENGINE SEEMS TO DOWNSHIFT BUT IT ACTUALLY REDUCED SPEED QUICKLY. I LOOK UP AT DASH AND SEE THAT IT SAYS, 'ENGINE POWER IS REDUCED'. I THEN NOTICE TO THE LEFT OF DASH THAT THE ENGINE PIC IS LIT UP. I PUT MY HAZARD LIGHTS ON AND EXIT THE FREEWAY RIGHT AWAY. WHAT I WOULD NORMALLY DO IS OPEN UP THE OWNERS MANUEL AND FIND OUT A LITTLE MORE TO WHAT'S GOING ON. I JUST PURCHASED THE CAR AND IT DIDN'T COME WITH ONE. I DECIDED TO TAKE SIDE STREETS THE REST OF WAY HOME. WHEN I GOT HOME I SHUT CAR OFF THEN STARTED IT UP AGAIN AND IT STILL HAD THE SAME MESSAGE.

ON 7/5/20 THE VEHICLE WAS IN MOTION GOING DOWN THE HIGHWAY AND THE HIGH PRESSURE FUEL PUMP MOUNTED ON THE ENGINE BROKE LOSE, DROPPED INTO THE ENGINE AND TORE APART THE ENGINE. WAS TOWED AND FIXED BY CLOSEST GM DEALERSHIP (DEERY BROTHERS, WEST BURLINGTON, IA). THERE IS A RECALL FOR A BAD WELD ON THE HIGH PRESSURE FUEL PUMP FOR 2016-2018 MALIBU'S RESULTING IN THE EXACT ISSUE I HAD ON MY 2014. THE DEALERSHIP SAID GM, CHEVROLET AND THE DEALERSHIP (WHICH IS A GM CERTIFIED DEALERSHIP WHERE I BOUGHT THE CAR CERTIFIED PRE-OWNED IN 2018) SAID THEY ALL BARED NO RESPONSIBILITY FOR THE ISSUE. I PAID $3,128 FOR THE REPAIR ON 7/17/20. TWO DAYS AFTER BRINGING MY CAR HOME, THERE IS AN OIL LEAK THAT WAS NEVER THERE BEFORE. THE DEALERSHIP SAYS THIS IS A HOLE IN THE OIL PAN, AND AGAIN IS MY RESPONSIBILITY TO PAY FOR IN FULL TO BE FIXED. I RECEIVED A LETTER FROM CHEVROLET ON 7/16/20 SAYING THERE IS A RECALL FOR MY VIN # FOR AN OIL PRESSURE VALVE. INCORRECT OIL PRESSURE COULD HAVE CAUSED THE HIGH PRESSURE FUEL PUMP TO EXPLODE CAUSING THE ISSUE ON 7/9/20. I DO NOT BELIEVE THAT BETWEEN THE TWO RECALLS ISSUED BY CHEVROLET FOR MY CAR MODEL I SHOULD BE RESPONSIBLE FOR THE FULL WEIGHT OF THE REPAIRS ON A CAR THAT WAS PURCHASED CERTIFIED PRE-OWNED WITH A WARRANTY TWO YEARS PRIOR, NOT TO MENTION I'VE HAD ALL REGULAR SERVICES DONE IN A TIMELY MATTER AT THE SAME DEALERSHIP, THAT HAS UNDER 90,000 MILES AND IS ONLY SIX YEARS OLD. THERE IS NO REASON FOR SUCH EXTENSIVE ENGINE DAMAGE TO SUCH A NEW CAR WITH NO PREVIOUS ISSUES.

MECHANIC STATED MY TRANSMISSION IS GOING OUT. AT 93,000 MILES THIS SHOULD NOT OCCUR. MY CAR NEEDS REPAIR ALMOST EVERY MONTH. TOOK TO CHEVROLET DEALERSHIP AND WAS TOLD THAT I HAD METAL SHAVINGS IN MY TRANSMISSION. THEN WAS CALLED BACK STATED I DONT. NOW ANOTHER MECHANIC STATED MY TRANSMISSION IS GOING OUT

WAS DRIVING AT ABOUT 55 MPH ON A STATE ROAD, ENGINE LIGHT CAME ON THE CAR SLOWED DOWN TO ABOUT 30 MPH IN GIVING GAS THE ENGINE RAMPED UP BUT WOULD NOT ACCELERATE. PULLED OVER AND STOPPED. TURNED OFF THE IGNITION WAITED A FEW MINUTES THEN TURNED THE IGNITION ON AGAIN. THE CAR WOULD NOT ACCELERATE. WAS ABLE TO GET IT TO A DEALER WHERE IT WAS DIAGNOSED AS NEEDING TRANSMISSION WORK. IT IS AT THE DEALER NOW 12/13/19. THE CAR HAS 92,000 MILES ON IT BOUGHT IT BRAND NEW IN 2014.

IT'S MAKING A UNKNOWN SOUND
