What 810 owners told NHTSA about the 2016 Chevrolet Malibu Eco

I will be driving at posted speed limits (typically 55 to 60 MPH) and while going up a hill, the engine loses power. I get a notice on my screen that states engine power reduced. Speed reduces to no more than 35 MPH. This can put others in danger if they are too close or if the roads are icy due to it being winter in Indiana. I put on my hazard lights, and I am able to pull off the side of the road, turn off the car for 5 minutes and restart it and have power back. But engine light remains on. Mechanics cannot find anything wrong. No warnings prior to the incident. In fact, the car loses power and then the message appears on screen. This has happened 7 times in the last 4 months.

I started smelling a strong smell of gas while operating the vehicle. Took to a dealership who diagnosed a turbocharger clamp and exhaust failure. From what I understand I am not the only one with a clamp/exhaust/seal problem. A friend of mine who owned a GM product had similar problems to the point her engine failed altogether. Please investigate!

When putting it in park and shutting the car down it says on dash to “shift to park.” There are other 2016 malibu that have this recall but for some reason not mine.

A couple days ago I went to drive my car and it took a second to actually turn on and it was shaking way more than usual and pooped up with a message saying “engine power is reduced” I haven’t drove my car since because i tried and it was moving very slow, and i also didn’t wanna cause further issues. For some time now my car has been shaky. i have taken it in and balanced my tires because of this issue and nothing had helped. I am always scared to drive it because it has been so shaky but now that this message has popped up it’s even worse and it’s during my whole drive. Also every time i park it isn’t connecting and says “shift to park” even though it is shifted into park. i have to shake it and press some button to go all register that it is shifted into park and can shut my vehicle off. I have read every where that this issue has happened to so many 2016/2017 chevy Malibu’s. I have read the dangers and i do not feel safe driving my car like this. I also didn’t have my car when there was a recall on this exact part before. and i’m guessing the dealership who had it before me did not fix it, causing the problems to worsen other parts of my car. I can’t drive this car due to the safety and i believe it should be a recalled. I am not totally sure what is doing it but as of all the other people online, they said it has to do the gas pedal (2k replacement) and fuel pumps and also could have burned wires which my car also has. thank you.

There’s a warning on the display that says ‘shift to park’ while the vehicle is already in park. This is causing the battery to drain/die and needs jumpstart everyday. Battery was tested and does not need to be replaced. I’m surprised this hasn’t been recalled yet. Online search ‘Chevy Malibu shift to park’ shows this is a common problem. Here’s a YouTube link that includes comments to prove this further. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car will not turn off when placed in the park position. A warning comes on that states "shift to park" when the car is already in park. I have contacted Chevrolet twice and was notified that their are no open recalls on this. This is a very common and known problem with 2016-2019 Chevy malibu as well as Chevy Cruze model. Chevrolet is no help in this matter. I feel this is a large safety issue as you cannot turn the car off. PLEASE HELP!

The main head gasket fails on these vehicles causing oil to leak everywhere and on top of electrical wires. The lost of oil has caused the engine to reduce the engine speed randomly on the highway which had risk of accidents multiple times, by unable to move the vehicle off the road at a reasonable time. The oil sips land on top of electrical wires which creates the risk of fire.
