2020 Chevrolet Malibu Complaint Log

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!

The contact owns a 2020 Chevrolet Malibu. The contact stated that while driving approximately 60 MPH on the freeway and depressing the brake pedal to slow down, the brake pedal was difficult to depress, and the vehicle failed to immediately stop. During the failure, the check engine and traction control warning lights were illuminated. The vehicle was slowly driven to the residence and parked. 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 85,547.

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.

When braking, the vehicle experiences a system failure. There is a loud impact, the dashboard shuts down, warning lights activate all gauges go to the left, and the vehicle loses power and enters a reduced speed mode before recovering. This has been ongoing and creates a dangerous driving condition. The dealership has had the vehicle over four months and has not diagnosed or repaired the issue. Please Note: I have attached the invoice sent to me on April 17, 2026, via email. The information in section 3 had been changed while I was sitting there. It originally state, engine repair needed. It said absolutely nothing about the reason I was there, which was what I am now describing. The description in section 3, has been worded incorrectly. It states I said, when coming to a stop, but it is not only when coming to a stop, but even if I am in flowing traffic and have to touch my brakes to slow down at any given time, there is a loud thump sound and a jolt, all of the dash lights come on, all the gauges go to the left, the warning lights are on and it has to sit there, not for a few seconds, but until those lights go back off and then it will move very slowly, until it decides to gain power. You have no warnings as to when it will happen or when the car will regain speed when it does happen. I gave pictures of the dash on April 17, 2026, as well and these pictures have the date December 31, 2025, on them. As I was having the issue while driving it to the dealership for repair. The invoice mentions [XXX] . I do not know her and have never met her. I only spoke with a man. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was unaware that when I purchased this vehicle that when the oil is low, the breaks go out and the break power booster shatters. The beaks have gone out on me 2x already and thankfully I’ve only had to replace the break power booster only once. Now once the oil is changed the breaks go back to normal, there is no grinding of any sort heard, so now going forward I pay real close attention to my engine, I listen and pay attention to the feeling and sound of the breaks, once the oil begins to become low knowing it’s time for an oil change around 40% is when I start to feel a bit of the difference in the breaks and I can feel a little bit of grinding, no oil light has come on at this time nor has the oil light or any type of signal has ever come on at anytime to let me know that it was time for an oil change. I’ve checked for recalls, I’ve checked message boards, mechanics have no clue about this problem, but at least my mechanic does now!

Shift to park. Im not able to park my car. W low miles. Chevy dealer stated not under warranty. Will cost 800+ to repair. Previous known problem (17-19). It was repaired my last malibu & was repaired under recall. Now a TSB has been issued by chevy for my 20 so they are aware. If they know it is a problem why is there not a recall? This happens often. Each time i park, I have to fight my gear shift & pray it eventually sticks. It does not seem safe. This is a new car & is unacceptable knowing the history. I can provide pictures or send estimate if needed.

A liAdjustmentght came on my dashboard. State power engine reduce period then it stalls when I press my foot down on the accelerator not giving it any power to go period then when I try to break it actually pushes my foot back off and it's hard to break period and when I press the start button to turn the engine on. It turns right back off after about.Maybe four or five seconds and no I just had to have a towed to my home. The special Coverage adjustment code in 182188250 is what my vehicle would apply to, but that code only covers the 2016 and 2018 models. What can I do now? Because it is under that code. But the dealerships won't cover it because they're saying my model is not but twenty twenty I need help please. I have 132k miles. Good condition. Why wouldn't letter models be covered under the same act?What would make it stop if it's doing the same thing?It did for those twenty sixteen and twenty eighteen models

Shift to park

When putting my car in park and turning the car off I get a shift to park message.

Car is not recognizing that is in park and displays a "shift to park message". Chevy has yet to address this WELL known issue and expects consumers to pay $700-$1000 for something they should be required to fix. This is a major safety issue

I was driving in the interstate at about 4pm on May 16th and the check engine light came on. Thus is nothing new because since I bought the car on Feb. 14th, 2024 the check engine light is on about 75% of the time. I went to use my brakes and the pedal was hard as a rock. I had to use both feet to depress the pedal to get the car to slow down. I brought the car to Autozone and they did a scan and it showed the Power Brake Booster Vacuum Sensor needed replacement. I ordered it and had a friend who is a mechanic replace it and the problem still persisted. My friend thought it was the Power Brake Booster Vacuum Pump. I ordered it and he replaced it and the brakes are back to normal. My research regarding this has found that his is a VERY common issue with this vehicle which has lead to costly repairs for many people and has resulted in a class action lawsuit. This is a SERIOUS safety issue! When a person can’t hardly press their brakes when driving that endangers the lives of the driver, the occupants of the car and every other person on the road. Why do we have to wait for people to be killed before this is fixed?

Very hard to brake, like stepping on a brick. Have to start breaking way in advance. Also keep getting a "shift to park" alert and car won't shut down and can't get out of it sometimes.

“shift to park” message appears after car has already been shifted to park. Will not allow car to be turned off as the car thinks it’s still not in park. Known issue with earlier models of the malibu that warranted a recall of models 2019 and before. Seems like this is a continued issue in the 2020 model
