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!

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

I had a constant message when turning off the car to shift to park. When the car was off, it would say shift to park on my screen. Apparently there is a recall for this, but my VIN number was not included in the recall. I had Several instances where I had been driving and my brakes locked up, and it caused my car to stall out. I would have to turn my car off and back on and sometimes it would work and that message would go away to shift to park. I eventually had to get a new transmission on a four-year-old car.

I was driving down the road and the car started slowing down and even when I would give it gas wouldn’t accelerate. After pullling over and allowing the cars behind me to pass I tried to pull back out into traffic and the car would not engage into gear. When giving the car gas it didn’t move. I shifted the transmission into park and tried shifting into every gear including reverse and the car wouldn’t go anywhere I had to sit in the road for about 20 minutes then the car shift very hard into drive and began accelerating. Now when trying to drive it every time it stalls out either when first trying to back up or take off or decelerates while driving down the road making me fearful for my life due to being hit from behind sue to no notice or warning before the car decelerates

I purchased a brand new, 2020 Chevrolet Malibu in March of 2020. The car had 90 miles on it when I purchased it. Those 90 miles were on it due to it being driven to me from Illinois because the dealership in Illinois had the exact car and color I wanted. In late 2020 I started having reduced engine power. The car would mis fire, randomly lose engine power and only allow me to drive below 40mph and the check engine light would come on. Early 2021, I kept having these issues and called the dealership where I purchased the car and they stated that the throttle body was bad. The throttle body was replaced along with a new hose clamp for the hose that connects to the turbo. I have continued to have the same issues since then. When accelerating above 4000rpm's, the car will stall and say "Engine Power Reduced." This causes the engine to completely stall and has almost caused me to be in numerous accidents. I called the dealership and they came and got my car from my house with a truck and trailer. I was advised to not drive it because one of the codes was "Engine Oil Pressure Circuit Stuck Closed." They picked it up on Monday, 10/2/2023. The next day, 10/3/2023, they called me with a diagnosis. Cylinders 3 & 4 were showing over 1,000 misfires, engine oil pressure circuit stuck off, engine oil pump pressure, and an under boost code. I was informed that my spark plugs may be bad. Turns out, according to them, it needed new spark plugs. The spark plugs and air filter were replaced costing me $500 on top of the $600 that I paid for the new throttle body and hose clamp for the turbo. I got my car back last Wednesday, 10/4/2023. Today, 10/10/2023. The dash said "Engine Power Reduced", the engine stalled, and I was almost hit again because my car would not accelerate. This is a common problem with Malibus and it is a serious safety risk! GM had a lawsuit against them in 2018 for this SAME ISSUE with Malibus. GM needs held accountable BEFORE a life and/or lives are lost!!!!
