2020 Chevrolet Malibu: check engine light

Filed Nov 8, 2026 · Electrical, Engine · FL

i am filing a formal safety complaint regarding my 2020 chevrolet malibu. my vehicle recently displayed a “service ESC” warning along with a flashing check engine light. these warnings appeared unexpectedly and have raised serious concerns about the safety and reliability of my vehicle. the electronic stability control system is an important safety feature, and a flashing check engine light may indicate a serious engine malfunction. i am concerned about the possibility of experiencing reduced engine performance, loss of power, or compromised vehicle control while driving. i am also aware of reports from other chevrolet malibu owners describing similar warning messages and electrical or performance-related problems. i believe these issues warrant investigation to determine whether there is a recurring manufacturing defect affecting these vehicles. i am requesting that the federal safety agency investigate these safety concerns and determine whether a recall is necessary

So while I was driving my car going 60 on the highway it seemed to be having electrical issues all the lights on my dash popped on then popped off and only a few lights actually stayed on I can't remember exactly but the check engine and my abs stayed on and then on my screen it read to me warning power steering fault my headlights were dimming on and off like my car was going to die, so I had to pull over for my safety and other drivers safety, so after I pulled over safely I shut my car completely off and waited about 5 minutes and turned it back on when it turned back on the only light that popped on my dash was the check engine light, but the check engine light had actually been on the dash for a while after I replaced the 21 fuses that were missing that I didn't know were missing when I purchased the vehicle as is from a dealership the only thing that made me decide to check my fuses was because my check engine light was popping on and off and would stay off for a while then come back on a code reader said it was something to do with my turbo that code it was just very odd and the car was shifting weird 3 or 4 months after the purchase date XXX also after I put all the fuses back in a ton of codes popped up others safety and mine were at risk as I didn't really have control of my vehicle when it was doing that and it started breaking itself when I wasn't even hitting the break it was like jolting it's self and stopping slightly. I took my car to AAMCO Total car Care for a free diagnostic test, and then I had recently took my car to a Chevy dealership in Nampa Idaho off garrity boulevard because online it had told me there was recalls for my car and that recall was exactly what I was thinking had started off as the original problem originally leading into the other problems I got told to bring my car in then the fed me information saying pretty much it was a bust and that specific Malibu has no recall I think they just didn't want to work on it

While driving, the brakes became hard and the vehicle was difficult to stop. The brake pedal required excessive force, brake assist was reduced, and the stopping distance increased, creating a serious safety hazard. The check engine light had been illuminated for approximately two years before the brake failure occurred. In January 2024, I reported brake-related concerns to a Chevrolet dealership while the vehicle was under warranty, but the root cause was not diagnosed. In November 2025, after the brake pedal became hard, an independent repair facility inspected the vehicle and determined the brake problem was caused by a failing engine vacuum pump. They advised that the vehicle be repaired by a Chevrolet dealership. By January 2026, the brake condition had worsened to the point that the vehicle was no longer safe to drive and had to be towed. A Chevrolet dealership later confirmed that the engine vacuum pump had seized and damaged the camshaft, requiring replacement of both components. The vehicle remains inoperable. The failed vacuum pump caused loss of brake assist, resulting in a hard brake pedal, reduced braking ability, and an increased risk of a crash. I believe this represents a serious safety defect because failure of the vacuum pump significantly impairs the driver’s ability to stop the vehicle safely. I understand GM has issued service information regarding vacuum pump failures on this engine, and I am submitting this complaint because I believe other drivers may experience the same dangerous brake failure.

Reduced Engine Power Light: The car limits acceleration, often accompanied by a check engine light. Stalling or Hesitation: Engine stalls or acts sluggish when accelerating, particularly in traffic. Limp Mode: The vehicle restricts speed, making it difficult to accelerate. The car stop working in the middle of the freeway and I was in the car with my child when it stop acceleration all gages in the car were going crazy, car was shaking bad finally car turn off. I was able to make it to the emergency lane of the freeway. There's similar complaints for 2020 Chevy Malibu but no recall has been done. Per my research it looks like a lot of this type of vehicles have problems with throttle body causing Engine stalls. Do the right thing and open up a vehicle recall, thank you!

Several things have been going wrong with this car. I have only had it for about 7 months. Minimal driving. Got the car with 84,000 miles and it now has 88,000 miles. About 2 months ago the check engine light came on. Got it into a shop and they said an oil change may possibly help with this. Got the oil change, cleared the code, drove it around and check engine light came back on. Brought it back to the shop and now the entire valve cover needs replaced. It’s been about 2 weeks since then haven’t had it fixed due to low funds. A couple days ago I was driving with two [XXX] olds in the car and was at a stop light. After about a minute the cars engine turned completely off lost all power including the center screen that displays your settings and radio, all lights, and the screen behind the wheel all with my foot on the break at a stop light. Due to this situation I was unable to turn my hazards on to alert the cars coming up being me at a green light absolutely panicked that we were going to get into an accident. A little while after the car turned back on, but unfortunately when trying to push down on the gas pedal nothing was happening. No revving sound and no movement of the car. Car still in drive. A police officer pulled up behind me to check if we were okay. He stayed to keep us safe until people came to push the car off to the side. During the push the wheel was almost completely locked up as well as the breaks. This is not the first time the breaks have locked up on me. Next day we got the car to a safe area to be parked. A couple days later went to try and turn the car on and immediately the car is shaking violently and making horrible noises. The car is unsafe for me to drive and unsafe for people on the road. This car is completely unable to be driven now also due to the horrible shaking. No recalls were found under my VIN, but all of these signs seem to be a problem for other people.
