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

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..

- Kokomo, IN, USA

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.

- Henderson, NV, USA

Car began to lose power while driving down the road, then began sputtering gas and creating black smoke. Engine pistons appear to be shot. Car has a little over 100k miles.

- Owingsville, KY, USA

This is not a safety issue but potentially it could be & I want GM to take action. I drive a 2016 Chevy Malibu. Beginning 2017, I started getting this message after ignition -€œSHIFT TO PARK-€. This is purely GM-€™s mistakes in designing the part. Solution is to replace the shifter asm completely irrespective of the warranty coverage. This is a common issue on multiple cars between 2016 to 2019, I suppose. I took the car to Ed Rinke dealer in MI back in 2018 timeframe & they said the shifter cable needs to be replaced. I did pay around $200 for the service & issue was gone for a while. It was back again in 2019-2020 timeframe intermittently. Its pretty bad now, I cannot shut the engine off & have to wait for quite sometime to get rid of the message & seriously do not know what to do. If I close the door & leave, message is still ON & battery drains out. I want GM to cover for expenses because dealership would want to diagnose when we all know what the issue is.

All of a sudden my Pistons just went in my car the whole engine block actually. There was never any warning or anything I got an oil change and after the oil change the check engine light came on plus it said service stabilitrak. Without the stability track you can get into an accident because the car is not in control the way it's supposed to be. The Pistons being worn in the engine block going. Without any notice of anything being wrong. Causes bad emissions leaks etc. The dealership knows about it. They can't give me a reason why the Pistons and the engine block went. Or why this service to stabilitrak came on. They're trying to say it's a pipe that has a dent in it. But the entire system is rotted out it only has 34,418 mi on it.

being unable to shift the vehicle into park. And when it is in drive and my car turns off because of the auto stop feature and turns back on it stated to act crazy and glitch -€¦this really scares me because when I am on the road and my kids are in my car the car shuts off. Very dangerous situation and I can-€™t believe that there is no recall in place for this. This is such a liability on GM knowing about this issue and not paying for the repairs and leaving it up to the owners expense knowing that this is a malfunction in the Chevy Malibu-€˜s
