2018 Chevrolet Malibu Electrical System

Hello, I own a 2018 Chevy Malibu. I previously had the recall repair completed for ECM Malfunction. Unfortunately, I am still experiencing the same problem that the recall was for. Since then, the issue has returned, and I am concerned that the original remedy did not resolve the safety concern. Can you please advise me on the next steps to have this issue re-inspected and corrected? Thank you for your time and assistance. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The mechanic discovered that the Battery Control Module harness had been damaged by water intrusion inside the vehicle. This damage prevented the vehicle from powering on, rendering it completely non-responsive.

When I turn my vehicle off, it displays “shift to park” I am trapped in my car because it does not turn off all the way and the door will not lock. I have to wiggle and re-crank several times to attempt to get my vehicle to shut off. My battery has gone dead several times because I simply couldn’t turn the car off with the shift to park displaying.

Car keeps giving a “Shift To Park” message when vehicle is already in park. Leaving the vehicle running and draining the battery, let me stranded a few times because it was dead. Tried almost everything to get it to go away but it keeps giving the same message everytime I go to park it and vehicle won’t shut off. Very inconvenient and unsafe, Doesn’t seem to be a recall or fix for this issue.

The contact owns a 2018 Chevrolet Malibu. The contact stated that upon turning the vehicle off, the message to “Shift to Park" was displayed and the electrical components remained on. The contact drove the vehicle to an independent mechanic where the vehicle was diagnosed. The contact was informed that there was faulty wiring in the electrical system. Additionally, the contact was informed of an undisclosed recall possibly related to the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 82,000.

The contact owns a 2018 Chevrolet Malibu. The contact stated while driving at an undisclosed speed, the low power mode warning illuminated, and the vehicle lost motive power. The contact stated that the failure occurred three times within a day. In addition, the contact stated that the night before, the vehicle was started; however, the vehicle then failed to start as intended. The contact stated that the vehicle went into auto theft mode. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact stated that the failure had previously occurred in July 2024. The vehicle was taken to the dealer and an unknown recall repair was performed. The recall repair consisted of ECM was reprogrammed and OAT sensor was realigned. The manufacturer was not made aware of the failure. The failure mileage was approximately 81,265.

My car keeps saying please put in park, even after the car is parked. If I don’t turn on and off the car multiple times shifting from park to reverse to get it to not say put in park, my lights in my car stay on and the battery will eventually die. Seems electrical, and afraid of it says please put in park, is it really in park if it says that?

this is a known issue with the 2018 Chevy malibu and other GM vehicles, where the vehicle is in park, but the car does not register that it is in park, and will not shut off. this has been happening in my malibu, and Is a large safety concern for me

I was driving my car and my entire car’s dashboard went out and the cars speed dropped I tried braking but they kept slipping. It was a very scary event for me as I was driving on highway 59 when this happened to me. The TCM is s a problem for this vehicle please recall this issue.

When putting gear shift into park the driver display on dashboard said not in park. The car would not fully shut off causing a safety problem. Could not lock vehicle. Was draining the battery. My extended warranty covered $382.59. I paid $177.32.

Mass air flow sensor has been replaced 3 times. Keeps going bad causing hiccups and hesitation. Very dangerous at times

Shift to park

On 9/22/22 I drove 2018 Chevy Malibu about 3 blocks and low fuel light displayed. The gas needle went past E. I had about a quarter tank when I last drove it. I drove about 2 miles, going 50 MPH and it began to sputter and reduced speed to 20 MPH. Very dangerous situation, but I pulled off on side of road. When tow arrived driver got in car and the gas needle moved back up to almost qtr tank and no low fuel lights or warning sound was generated, engine turned over but it would not start. Had it towed to gas station and put gas in it, still would not start. It was not out of gas. The reading was incorrect. Towed to dealership and they still have not found the problem over a week later. Stated it could be an electrical problem. Electrical service repair tech is checking it. I have seen similar scenarios reported on this site. GMC/Chevrolet needs to do a recall. This is a dangerous situation. Luckily I wasn't on a very busy road.

When I come to a complete stop and take back off, my car flashes a warning " steering assist reduced. Drive with care" this just started 4 days ago. Within those 4 days, every time it starts back up all lights flash on then back off. My check engine light has not gone back off since 1 day ago. I have done research and I have realized that this is a common problem for this make and model car. Most complaints regard power steering control. I'm wondering what can be done, because there has not yet been a recall for this issue and it is a complete safety hazard, especially with children in the car. I would hate for any lawsuits to come from something that could have been avoided.

Car does not recognize when it is in park despite attempt by dealer to fix

When going to shut off the vehicle the display comes on "shift to park" and will not allow the engine to shut down. Must turn car back on, place into a gear, place into park and turn off power again. This has occurred multiple times over the past few days. It will also take 3 or 4 cycles to finally get the car to shut down completely.

Something draining my battery done put a new battery in it no lights or anything on when I get out been going on for bout 3 months now

When trying to turn off the car after putting it in park, the panel reads that I need to "Shift To Park", although the car is already in park. With this issue it causes the car not to turn off. This is an intermittent issue, and does not happen all the time.

whenever i put my car in park, i get a warning message to put my car in park, even though it is already in park. i have to jiggle the shifter for the warning to go away. sometimes i can't even tell if the car is in park or not

Intermittent problem with the shift to park alert coming on after putting into park. Power remains on, movement of shifter back and forth usually causes it to go off. Message sent to manufacturer was cut off in process by customer service? I will try using usps. Very annoying and unsettling problem,many similar complaints online. Dealership says replacement of shifter for about 400.00 should correct it?A recall should be made with this many issues.

THE CAR SAYS IT'S NOT IN PARK WHEN YOU SHUT IT OFF. THE FOB SEEMS TO NOT RESPOND SOMETIMES. SOMETIMES IT WON'T START AND TELLS YOU TO PUT IT INTO THE CENTER CONSOLE POCKET BUT IT STILL WON'T RESPOND. IT WILL SAY THERE IS NO FOB IN THE CAR. I REPLACED THE BATTERY TO MAKE SURE THAT WASN'T THE ISSUE. EVEN WITH THE FOB IN THE CAR, IT SET OFF THE ALARM WHEN I TRIED TO START IT. IT TOOK ALMOST 5 MINUTES FOR IT TO RESPOND TO SHUT THE ALARM OFF BUT IT WOULD LET ME LOCK THE DOORS WHILE SITTING INSIDE IT. SO IT REGISTERS THE UNLOCK AND LOCKING MECHANISM BUT NOTHING ELSE SOMETIMES.

WHEN PUTTING MY CAR IN PARK TO TURN OFF, THE CAR DOESN'T RECOGNIZE IT'S IN PARK AND THUS WON'T TURN OFF. AS SUCH, I CANNOT LEAVE THE VEHICLE.

I HAVE A 2018 CHEVROLET MALIBU AND I HAVE TROUBLE PUTTING THE CAR INTO PARK. THE PROBLEM IS THE GEAR SELECTOR SWITCH. WHEN YOU PUT THE CAR FROM DRIVE INTO PARK A METAL BAR PUSHES UP ONTO A BLUE BUTTON WHICH SENDS A SIGNAL TO THE CAR'S COMPUTER THAT THE CAR IS NOW IN PARK. I SPOKE TO A DEALER AND THEY TOLD ME THAT 2017,2018 AND 2019 MALIBU'S ARE KNOWN FOR THIS PROBLEM AND IT WOULD BE $900 TO CORRECT THE DEALER KNEW WHAT IT WAS BEFORE I EVEN FINISHED TELLING THEM ABOUT THE PROBLEM.I NEVER KNOW IF THE IS IN PARK

WHEN I PUT MY CAR IN PARK, A MESSAGE APPEAR ON THE DASHBOARD 'SHIFT TO PARK'. IT WON'T LET MY CAR TURN OFF COMPLETELY

WHEN PUTTING THE VEHICLE IN PARK, A MESSAGE COMES ON THE DASH SAYING 'SHIFT TO PARK'. THE VEHICLE IS ALREADY IN PARK, BUT THE CAR DOESN'T PICK THAT UP. IT IS A KNOWN CHEVY ISSUE THAT THEY HAVE YET TO RECALL. HAPPENS ALMOST EVERY TIME I DRIVE. *TR
