2020 CHEVROLET MALIBU Complaints

When I was in a car accident, the airbag exploded. However, the airbag's balloon-like fabric material did not deploy, and a metal part even flew off the steering wheel and exploded, hitting me in the chin. So I lost about half of my lower jaw, most of my lower teeth, and some of my upper teeth. In the process, I underwent a total of three surgeries: emergency, infection, and reconstruction surgery. In the future, I may need to undergo additional implant surgery and additional reconstructive surgery as needed. There has been no formal component inspection by any agency since the accident and there were no relevant warnings or symptoms prior to the accident.

The steering assist is reduced will come on. The car randomly turns itself off and back on when at a stoplight; this has happened four times now. I worry that it will shut off and not restart creating a hazard on the road.

Started today, I would put my car in park and I’d would display in the dashboard “Shift to Park” even though I’m already in park. I tried to turn my car on and off and switch gears but everytime I turn it off and it’s in park, it would keep reading that message. It eventually stopped but I don’t want this to keep happening.

I was hearing a grinding noise when applying brakes so i had a mechanic change my brakes. He said they didnt need changing but i had him change them anyway. The noise didnt stop but we wasnt sure why it was making the noise. While driving down the highway, the break pedal became to hard to press. At that point I was in heavy traffic and had to use my emergency brake system to avoid collission with multiple vehicles. Upon taking my vehicle to the mechanic it was observed the vacuum pump had broken inside the motor. After the mechanic changed the part and cleared the broken parts out of the motor, within 6 months my breaks are acting funny again making loud noises when applying brakes. I'm terrified to drive long distances.

The power train may be defective. The auto shut off on the vehicle completely shuts off when you stopped at a red light. The entire vehicle restarts, and then 12 lights appear on the dashboard. The car starts shaking sometimes when it's being driven. The vehicle is currently being looked at, at the dealership. I was told that the diagnostics is reading 19 codes and misfires.

While driving on expressway, vehicle slows down suddenly. Service ESC, power steering, and engine light comes on and car tuns off. This has happened 8 times in two years with no fix from GM. This happens with no warning the car just stops driving and loss of power steering occurs. The dealership has tried to fix 8 times now with no real fix to the issue.

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!!!!

I was driving down the hwy and all of a sudden, my engine lost power and my brakes harden. I could not brake and nearly lost my life and my sons.

This issue started at approximately 19,500 miles. While accelerating to enter a highway or to pass a vehicle going less than 55mph on a two-lane, Service ESC light appeared on dash. Loss or power was also immediate and if I tried to accelerate to maintain speed, engine was very rough in responding with no acceleration. Engine continued to run. Within 30 seconds or so, acceleration is restored, and check-engine light was flashing. Check-engine light stopped flashing after a minute or so. Initially, this only occurred occasionally during fast acceleration as mentioned above. Lately this has happened during continuous acceleration, such as using cruise control, while climbing a low incline hill (~15°). Over the past year or so, Chevy dealer has replaced, pistons, fuel injector, and did a carbon cleaning of engine. No solution yet.

Car has stalled out, or acted like it's going to stall out several times. No check engine light on so unable to identify the issue. There are recalls for other Malibs for similar problems, but it states this model is not affected.
