2021 Chevrolet Malibu Electrical System Problems

I was driving and car suddenly reduced speed,engine light came on and message came across dash “engine power reduced” and a text was sent to tell me I have a transmission issue. Now car won’t drive past 25-30mph dealership indicated this is a faulty gas pedal which cost over $600 to repair. Did my research and this is apparently a “known” problem common in 2016-2022. Vehicles but is not an official recall. Also dealership said only “certain” vin numbers with this problem are covered. I have a 2021 and I am not one of them. Not fair. It’s a known problem it should be fixed.

Dear NHTSA: I am submitting this complaint because my vehicle, a 2021 Chevrolet Malibu (VIN [XXX] ), is included in Emission Recall N252516900 issued by General Motors concerning the Fuel Pump Power Control Module. Despite that inclusion, I have experienced the following: - A prior near-fatal incident in 2023 when the vehicle unexpectedly shut off while stopped at a red light (engine stall) due to the root defect. - The dealer has informed me I now need a new 12-V battery (just over one year old), a new AC compressor, and a new drive/serpentine belt. - The defect referenced in the recall (interruption of fuel flow) is reasonably the root cause of these consequential failures (battery stress, accessory drive stress). - I have been without the vehicle for 11 days, have not been provided adequate interim mobility support, and have not received timely resolution from GM under my Case #XXX (agent Jasmine who has followed her company's protocol while remaining helpful and empathetic; supervisor Stephanie called October 17, 2025). Requested relief: 1. That GM be required to pay for the recall work (module replacement) **and** reimburse/cover the consequential damage (battery, compressor, belt). 2. Interim remedy: loaner vehicle or rental reimbursement for days without vehicle. 3. Acknowledgment of the safety risk posed by the defect and record of the stall incident. Thank you for your attention to this matter. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I went to do an errand pulled in to parking spot put car into park shut it off. Car dash repeatedly said put car into park. All dash lights, would go on from left to right and shut off, this included the center console. I tried over and over to start car and shift but it wouldn’t go. It just kept repeating shift into park. It took 95 mins before the car would start. Then the RPMS would rev way past what they should. I lived 30 miles away. I made it home slowly. The next morning I took to my son tha is a GM certified mechanic. I’m not sure what he did but it’s running smoothly again.

My car has about 82000 miles and while driving it stated that I was shifted to neutral and needed to be restarted. After a few seconds the steering wheel locks up and I can’t press the gas anymore, even though the car is still in drive. This happened about 6 times on the half mile drive home. I haven’t been able to diagnose it yet since the dealership is backed up for a month. I think it’s the neutral safety switch

After shifting into park and turning vehicle off -warning beep "place vehicle into park" comes on. It takes several "jerks" of gear shift to turn off. I'm scared its not in park and may roll.

I was driving the car on the highway and “SERVICE ESC” popped up on my dash. Engine power reduction kicked in which caused me to have to erratically pull over to the shoulder. Brakes did not engage properly. When the “Service ESC” warning comes on the dash, the engine, transmission, and brakes stop functioning properly. The gauges start fluctuating up and down and the gps goes out of whack. Transmission won’t shift gears and the car will sometimes shut off all together.This is a very common problem with the Chevy Malibu from 2017 to present. I did my research and there is a lot of disgruntled owners that have experienced this problem. Type in “service ESC Chevy Malibu” on google, Reddit, or YouTube and you will see. I personally know two other Malibu owners with the same issue different years and mileage on there Malibu. I honestly can’t believe with all the information out there on these Malibus having the same issue there has not been a recall yet!

I recently purchased this vehicle. Within the first week I was trapped in the vehicle sporadically. When I try to put my car into park, the car keep repeating "shift to park". I have tried to put the car through all gears, backing up and parking repeatedly to attempt to put the car back into park. I have been trapped in my car for hours trying to put it in gear. When I reached out to the dealership they stated that even though there is a recall for most Malibu's; however, my VIN number does not qualify for the recall.

I own a 2021 Chevy Malibu and I have been having issues with my transmission since November 5,2024. I was driving along at about 30 miles per hour When all of a sudden the car would not accelerate so I put the car in park and put the car back in drive and accelerated but only revved up but still would not move. I called a mechanic to look at my vehicle and he checked that I had transmission fluid and it was full. Upon further inspection he plugged an OBD code reader on my vehicle and came up with a P0700 Transmission Control System Malfunction which is the output shaft speed sensor or the vehicle speed sensor? I spoke to a shop about the problem and they said that that year and model car has a lot of complaints from owners. They said that it could cost up to 3,000 and up to replace the transmission. I think that it should be investigated for that issue?

When I turn off the car it displays a 'shift to park' message and the car tries to roll if I take my foot off of the brake. My [XXX] was beside the car and was almost run over. This is a problem that the car rolls away. I have to restart the car continuously and toggle the gear shift to get it to stop. It will not let the lights turn off and radio and/or the other components in the car and is running the battery down. There is a recall for this problem but it is VIN specific and my car is not included. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle says shift to park. Even though the vehicle is in park. It then causes the vehicle power to remain on and kill the battery. I’ve seen multiple instances of this same problem on the same vehicle as mine and many other GM models. My warranty ran out in January (of course) and now the issue is occurring. I’ve been stranded with a dead battery 3 times already due to this. It’s literally a microswitch not functioning correctly to tell the computer that the vehicle is in park.

Car is not registering that is in park. When I put the car in park the message on the dash will ding and say "shift to park" even though it is already in park.

When trying to turn the car off, it will not allow me, warning light comes on saying shift to park. This has happened several times over the past week. I have to continuously turn the car on and off, put in drive then back to park before the message goes away, allowing me to turn off the car. I am 3k miles out of my bumper to bumper warranty, so the dealership is charging me $500.15 for a new shifter assembly for what they said was a common failure in GM cars. If its common then it should be a recall for several make and model years. My coworker has 2021 Blazer and the same thing happened to her but she was still under warranty so her repair cost $0.

Vehicle has a repeated issue recognizing that it is in park when trying to turn vehicle off. This causes concern that the vehicle may not actually be in park, will not fully power down therefore draining the battery and leaving driver stranded, or lead to other body control module/shifting problems. This is a known issue with GM spanning multiple years and multiple models. The only official fix is to replace the entire shifter assembly with an updated version which can be a couple of thousand dollars. GM refuses to cover the cost knowing that they installed a faulty part during assembly.

When I move my car to park and shut off the vehicle it shows a "shift to park" message. This keeps my car from shutting off on a regular basis.

Malibu will be in park, engine off, but when exiting the vehicle a message will appear "SHIFT TO PARK", although the vehicle is in park. The electrical will not shut off, which is a hazard, as the vehicle's battery remains on. I am forced to turn the car on, shift to a different position (not "park", and then forcefully shift back to park). I contacted the dealer that has done all of my work, they were aware of the problem and offered to fix under warranty. They claim to have replaced my transmission harness. The problem was fixed for about one week, but now the problem has resumed sporadically. I have contacted the dealer again as of this morning to seek resolution. The consumer stated that the manufacturer has not resolved the issue yet.

3 times now, the car has turned off while in gear or in motion. In an Arbys drive thru on a hill above a highway. Backing out of a parking spot in VA. And pulling through a busy intersection in VA. The safety hazard is that you lose power brakes and steering when a vehicle isn’t running, one could easily be unable to avoid a wreck. Also the general danger of your vehicle randomly shutting off. No warning lights appear before during or after this happens. The 3 dealerships that have looked into the issue state they are unable to recreate the problems and there’s no codes stored in the system so there’s nothing they can do. No police or anybody other than the dealerships have inspected the vehicle. These issues began happening less than a week after purchasing the vehicle.

THIS WAS A RENTAL CAR, EQUIPPED WITH AN ELECTRONIC KEY FOB AND A STARTER/TURN ENGINE-OFF BUTTON ON THE DASHBOARD. THIS PARTICULAR VEHICLE COULD BE LOCKED REMOTELY FROM OUTSIDE THE VEHICLE, WHILE IT CONTINUED TO RUN. ADDITIONALLY, IT APPERED THAT AN OCCUPANT OF THE LOCKED VEHICLE WHO DID NOT HAVE AN ELECTRONIC KEYFOB IN HIS POSSESSION COULD NOT OPEN THE DOORS FROM THE INSIDE. THUS, ADULTS OR CHILDREN COULD BE ASPHYXIATED UNDER CERTAIN NOT-TOO-HARD-TO-IMAGINE SITUATIONS.
