Owner reports

Selected complaints filed with NHTSA by 2021 Chevrolet Malibu owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2021 Chevrolet Malibu. The contact stated that while starting the vehicle, all the lights on the instrument panel illuminated, and the engine started to choke. The Service Vehicle light remained illuminated after the other lights turned off. The engine started choking again and failed to start. The vehicle was towed to a certified mechanic and was diagnosed with an inoperable fuel pump power control module. The mechanic informed the contact about a recall associated with the failure and referred the contact to the dealer for assistance. The vehicle was not repaired. The contact stated that the failure reoccurred the next two days. The dealer was contacted and confirmed that the VIN was not under recall. The manufacturer was informed of the issue and confirmed that the VIN was not under recall. …

The contact owns a 2021 Chevrolet Malibu. The contact stated that after parking the vehicle and pressing the START/STOP button, the vehicle did not immediately turn off with the message "Shift to Park" displayed. The cause of the failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 34,200.

I purchased this vehicle in April of 2026, 4 days after bringing it home it began displaying a "Shift To Park" message in the dash, essentially making it so the vehicle will not shut off even when the vehicle is in park. Took it to a shop and they diagnosed it as a common issue across the 2021 Malibus and stated the entire shifter assembly needed replaced. Have not had it replaced yet due to not having the funds to replace the entire assembly, but was informed eventually the problem will progress to a total loss of being able to turn the vehicle off resulting in the vehicle essentially dying and requiring a jump start where the issue will display on the dashboard again until the internal micro switch is replaced. I believe this issue should be brought to GMs attention and a recall should be issued, seeing as they are aware it's a known issue in malibus. …

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. …

The computer was not recognizing my car being in the correct gear shift. It did this for a few days until finally, I couldn't drive it. The car would not recognize any part of the gear being in the correct position. The car would not move forward or reverse, resulting in a tow. The mechanic at Reed Lallier Chevrolet in Fayetteville NC was even able to guess my car make and model from the symptoms I reported (which was later discovered, in my case, the gear shift link had loosened), and confirmed that if this happened while in motion, it would have been very dangerous. He also said they had 3 other cars that SAME DAY that had different causes but the same exact faulty gear recognition, with all of them being recent-year Malibu Chevrolet models AND the following day when I was doing my follow-up call concerning my car, 2 more were brought in with the faulty gear recognition issue.

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?

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.

The car has an issue recognizing that the car is in park when trying to turn off the vehicle. A message on the dash will appear "Shift to Park". The car has not been inspected for this issue, but it does repeatedly happen, not every time I turn off the car, but it happens pretty frequently. If I am unable to get the shifter to fully engage the computer then it won't let me completely power down the vehicle and drains the battery. I've had to get a battery replaced before due to a mechanic moving my car after inspecting it for a different issue and leaving the "Shift to Park" signal on and ignoring it. This left me stranded with no battery and a mechanic denying remediation for the dead battery. Many other similar gmc models have the same issue as me.

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.

The Chevy Malibu is displaying a "Shift to Park" message even when the gear selector is physically in the Park position. This indicates that the vehicle's computer may not be recognizing that the vehicle has been placed in Park, which is commonly associated with a faulty or failing internal park-position sensor/switch. The issue is affecting the vehicle's ability to shut down properly. It is necessary to turn the vehicle off and back on multiple times before the system will recognize that the vehicle is in Park and allow it to shut off completely. If the vehicle does not recognize the Park position, it may remain partially powered on and potentially drain the battery.
