While in rush hour traffic going 75 MPH on an interstate free way in the most left lane the car entered low engine power mode without warning resulting in the car being only able to go 40 MPH and with losing the ability to easily steer. Thankfully the driver was skilled enough to manage maneuvering through traffic moving at high speeds without getting hit and able to pull over to the side of the road. After traffic slowed down the driver was able to get the vehicle home without issue and investigate the problem. As it turns our there have been multiple reports of the car having this problem due to a faulty sensor on the pedal system that GM has acknowledge through extending the warranty on that specific part but has not been required to issue a recall on it despite the chance of death from an accident at high speeds that could occur from this issue happening without warning. The vehicle was taken to a dealer who confirmed it was the defective sensor.

While driving, my car will read reduce power engine, and go to 40mph and then i have to pull over and turn off my car and restart, sometimes it will dismiss the problem and drive normal but sometimes it goes right back to reduce power engine and 40mph again. My gears sometimes will be stuck in park.

Engine/Pistons Car has 80,000 miles and the engine/pistons have gone out on this car. I have had the car inspected by the Chevrolet dealership and they were shocked that a car that has been taken care of so good with so little miles is giving me a problem so major and expensive

I-??m struggling financially and In a hole now the engine light is on and I can-??t get to my destination without going more then 30-40mph because -??engine speed reduce-?? appears on my dash board and reduced the speed and not only is this inconvenient and annoying but also dangerous I dam almost got into accident because of this I was driving in the highway about 65-70 mph when this happen with a 18-wheeler behind me not only was my daughter-??s life and mine put in danger. But the person driving the 18-wheeler. He definitely lost somewhat the control to swerve my vehicle it was a miracle of god no other cars where next to us and that nothing happened.their is so many 2016 Chevrolet malibu like this that I hope from the bottom of my heart that their is some compassion for this issue where they can make the issue get recalled.

And like i said not only for my safety but everyone around I am not the only one with this issue if the make in model. Their is hundreds of us !

Reduced engine power alert. Ongoing issue since 2019

- Chicago, IL, USA

I have had several issues with my 2016 Malibu. 1st: Putting my vehicle in park sometimes it does not register that it is in park. I have to turn the car on again and try moving the shifter until it registers. 2nd: when accelerating at times i get a stabilitrak error and a check engine light that causes a loss of power. This can happen in the middle of the highway which will cause an inevitable accident. 3rd: saving the best for last. Thw vehicle has recently lost power while driving and won't allow acceleration. Once i stop the vehicle stalls out completely and won't register the gears so i can't out it into park or anything. I was stuck at an intersection and couldn't move. It wouldn't turn fully off because it didn't register it was in park. And it won't turn on or start because it isn't on or off. I maintain my vehicles and correct all fixes recommended. Brought it in to have the issue looked at and was told that there were A LOT of error codes. They cleared them. But this has gotten ridiculous. GM needs to figure their stuff out..

When the vehicle is in drive, the display will say "reduced engine power" and will drop the car to 25mph even on the highway. I've almost wrecked from this issue. I've seen where GM has had class actions on this prior but it was never recalled.

- Tahlequah, OK, USA

When I accelerate, it hesitates to pick up speed. Once I made it to 75mph, a warning message came on that said engine power reduced and the check engine light came on. I looked up the issue and saw that several people with the same car were having the same issues. I added a gas treatment like they suggested but the light is still on. I have not been to a dealership or mechanic shop yet due to not having the money. But if this is a common problem then Chevrolet needs to pay for repairs. If my car fails while I-??m driving, I could cause an accident.I have had the throttle body cleaned before and the wheel sensors but I am still having issues.

- Kinder, LA, USA

I was driving on the freeway at about 65mph, and the car shut down on me. It was extremely dangerous to get over on the freeway with no power. 2 warning lights came on. The Stabilatrak, & the check engine light. I pulled over & called for help. I had the car taken to the service department at the dealership. They contacted me & informed me that a piston was cracked, & the ECM had to have a software update. They are charging me $5,389 to repair it. The car only has 8,000 miles on it. There are recalls for this exact problem, but do not apply to my specific VIN#. My car is a 2016, so I am out of warranty, but this should not happen with a vehicle with this low of mileage.
