What 78 owners told NHTSA about the 2021 Chevrolet Malibu Eco

A screen popped up saying “reduced engine power” I was already Omw to the shop to get one thing fixed. When they tried to pull my car in they say they he car wouldn’t drive and it was hard to accelerate and they had to put it in Neutral to get it in the shop. They said they fixed the problem but when I left to go into the main road, my car wouldn’t accelerate to the speed I needed and cars were coming. They were beeping and thank God they were able to slow down because they’ve would’ve hit me. The car does not accelerate and the manias can’t figure out why. Upon doing my research there are 100’s of folks saying the same thing. Right now I am out of a car, I literally just moved on 6/30 and not only do I work DoorDash, I have a day job and an overnight job. My car is how I make my money and this issue is putting a lot of stress and frustration on me because I need to get to and from work to pay bills. I am waiting to hear back from another mechanic which is even more stressful. Waiting, trying to figure out who can fix this issue and what the issue is.

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.

The engine light was on and had my vehicle was stalling while driving in traffic. The service code P1101 was on and had my vehicle fixed. The light stayed off for few months then same service code is back on. I've read that there was a recall for 2019 models with same issue. My vehicle is a 2021 Chevrolet Malibu LT and has same engine as the 2019 models.

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 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!

It says that my engine had a problem. It told me to press my brake to start my car. But then it just kept shaking like it was trying to start. I have also had a notification saying to put my car in park when it already was. Today my car just stopped in the middle of the road in heavy traffic. We could have been hit getting out of the car or someone could have hit my car. It was towed to the local Chevrolet dealership to get checked out to see if it could be a recall. I don’t know what is wrong with it yet. There were no warning lamps prior to the failure. They appeared right when it happened.

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?

Placing the car in park, turn off the car and a message appears saying to shift to park. The vehicle is not recognizing when the car is in park not allowing me to turn it off. I have to turn the car on and off multiple times until it decides it wants to finally shut off.

My 2021 Chevy Malibu's transmission is shredding. The car does not go into D right away, it acts like the engine is completely disengaged. If I go from R to D several times, the engine sometimes revs very high when I step on the gas and then lurches the car forward a few feet. Sometimes, when I try to get the car into first gear, the car will completely shut down with the vehicle in D, and I have to put it in P and restart it. Other times, I can put it in different gears a few times until R engages very sharply (the whole vehicle moves), and then it will engage into D just as sharp. My check engine light will come on and go off, although it never did before this problem started, and whenever it comes on, the car will stop working whenever I stop the vehicle and try to go again (i.e. red lights). I only have one car and am forced to continue to drive this vehicle while I wait on repairs. I have two kids and I am terrified that my transmission is going to completely give out while we're driving, or the engine is going to start shutting down while the vehicle is in motion! The dealership told me that two other Malibus were in with the same exact issue within days of each other. A GM inspector confirmed the transmission is shredding. My friend had a Chevy Impala that did the exact same thing

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.
