I had my vehicle for about 2 years. I noticed that after I went over a certain amount of mileage, my car went into an engine power reduce mode. With the engine power reduce mode my vehicle could only go 25 mph. This was happening to me when I was driving on major highways, etc.. I would have to pull over and stop the vehicle because after certain amount of time it also would tell me oil pressure low to stop engine. I took it to the Chevy dealership to have it looked at. I got the runaround with trying to figure out exactly what the issue was. They kept telling me that it was something else I spent over $1600 in repairs due to them, telling me that they found the issue and corrected it. After about another week or two, The same issue happened, engine power reduced stop engine oil pressure low. The most dangerous part about it is again I-??m driving on interstates heading to work, etc. and the car is slows down on the interstate not allowing me to go over 25 mph again having to pull over on the interstate to give the car a break, crank it back up and get to a safe location. After having multiple mechanics look at it, still unable to fix. It started to get worse where once it pops up engine power reduce, oil pressure low stop engine, the car started jerking & shaking really bad. The only way to stop this from happening is to again shut the car down. I can-??t keep shutting the car down in the middle of the interstate and on major roads. I took the vehicle to the Chevy dealership first they couldn-??t find the issue. They said it was another issue that wasn-??t even the issue so I paid over $1600 for nothing. I took it to Rick Hendrick, who couldn-??t find an issue and all they could tell me was to trade it in. This vehicle issue needs to be recalled. My bf is now having the exact same issue that my car was having & after researching, others are as well. Same year, same model, just a different color. This vehicle needs to be recalled for this ongoing safety issue ASAP!

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.

Reduce Engine Power - vehicle decreased acceleration drastically while driving on the highway.

- Smyrna, TN, USA

The contact owns a 2016 Chevrolet Malibu. The contact stated that while driving at an undisclosed speed, the "Reduced Power Engine" message displayed and the vehicle inadvertently decelerated. The brake pedal was firm while depressed and the vehicle failed to stop immediately. The vehicle was towed to an independent mechanic, who diagnosed that the vacuum pump needed to be replaced. The vehicle was then taken to the dealer, where it was determined that the vacuum pump deteriorated and went into the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 138,000.

- Henderson, NV, USA

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!

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.

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.

- Maybrook, NY, USA

Vehicle check Engine light on, showing "Reduced Engine Power." Vehicle still able to be driven, but will not accelerate with any proper pace or power. Cannot get above 3000 RPM without losing power, has put me in two dangerous situations in the last two days that almost made me lose my life. On highway, trying to accelerate to match traffic speeds, lose power and had to dive to the emergency lane to not get plowed by a truck. Today, was city driving, at a red light, could not accelerate and had to dive to a crawl the vehicle into a turn lane where I ended up sitting for about 10 minutes till the engine offered enough power to keep driving. By all information I can find online, it seems it is similar to the issues presented by others online and might tie into "Special Coverage N182188250 Loss of Continuity within Accelerator Pedal Position Sensor Circuit" that I found here: [XXX], this issue has been going for about 3 weeks to a month and is only getting worse. I did stop at McCarthy Chevrolet of Overland Park to have codes run about on [XXX], the codes showing do not show in the above link...codes: U1502, U0422, P06DE, C0760...those all present on the paper as "Current." I have not had it diagnosed yet, planning to, service is just so expensive. I have had the car in my car for 1 year and 1 month, purchased from MAX Motors in Harrisonville, Mo. Reporting here as I also saw online that others are facing the same symptoms, and that there is a suit that might be addressing these issues: [XXX] Every time the car is turned on, the warning mentioned above shows. See picture attached. Does not matter what type of driving or set "speed limit" issues show. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car was started shaking really bad and the stabili trak sensor came on. My engine had to be replaced in February 2023. My car was at 66K miles. I rarely drove it. I worked from home for 3 years due to the pandemic. I purchased the car with about 12K miles. I was on my way home and my car just shut off. I could not get it to start at all. The stabili trak light came on. This was in January 2024 with 75K miles. The tow truck driver told me he had picked up multiple Chevrolets experiencing this same issue. It took the dealership almost two months to figure out that the crank sensor needed to be replaced.
