Vehicle randomly presents an engine failure making impossible any acceleration. Engine light comes on as well as the traction control light. It displays a message 'engine power is reduced'. this forces the driver to have to pull over regardless of traffic or unsafe conditions. The car has to be turned off and back on after approximately 20 seconds in order to reset the traction light only to off, to be able to continue driving.

August 31, 2019 - purchased a 2017 Chevy Malibu at the dealership April 4th, 2021 - my car had a rough running engine with the indicator lamp on. I immediately took my car to be inspected (attached below), a technician found dtc P0300 set along with a misfire low compression in one or more cylinders. He concluded the condition was caused by a damaged piston. My mechanic showed me a bulletin from GM describing this exact issue and then recommend me to get in touch with the dealership that I bought the car and or the manufacturer. April 5th, 2021 - the GM reps that I talked to concluded that my warranty ended and denied any assistance from the manufacture. They claimed to not find the bulletins that I attached to this form.

While driving on multiple accusations my engine light would come on and go off within minutes and not return till I turn the car back on or while driving later on in the day or days after seeing the light come so I was unable to bring it in to get checked out properly. A month passed when the issue appeared and when I decided to go into the dealership to possibly trade in my car the light was not appearing for days beforehand and things were normal till a a couple days after I left the dealership my car read on the dash 'reduced engine power ' I wasn't able to accelerate quick enough in the middle of traffic on military trail and belvedere I had to pull through a walmart parking lot to avoid on coming traffic and bring the car to my home close by very slow and sluggish due to not getting any acceleration from me pressing on the pedal. The dealership wants to replace my fuel pump system at a cost however it has a current recall for my specific make and model.

This issue has happened twice. The first time it happened it was in motion on the highway and a message appeared on the dashboard, "engine power is reduced." It began deaccelerating from 75 mph to 20 mph. I had to quickly pull over the car to the side of the highway and I cut the car off. I truned the car back on and the message went away. The second time it occurred the vehicle was in motion on the highway again when the engine light came on in the dashboard with a message, "engine power is reduced." The car was going 80 mph when the message came on this time. I reached out to the Chevrolet dealership and they confirmed there was not a recall. I did some research on the issue and discovered that there have been other people with the same vehicle who have experienced the same issue.

On 03/10/21, I was driving North on a busy highway. I approached the stop light and reduced speed. I came to a full stop and the car shut off completely. The check engine light came on briefly, then lost all electrical power. I had no hazard lights, no radio, no dashboard, nothing. After being stranded for 5 min like that at a very dangerous left lane stop, the car finally restarted. Called onstar immediately to scan the car for codes - they found none. The issue of the car intermittently shutting down like that has happened multiple times since October of 2020. Taken the car to Chevrolet dealership multiple times and was told they cannot find anything wrong. I currently have it at the dealership and am being told they can find nothing wrong despite four different people in my car witnessing it happen to me more than once and my providing a log of every time it's happened.

I purchased the vehicle in 2018 with 20,000 miles on it. My check engine light has been on more than 7 times in the past 2 years. I had to have the fuel injector worked on, sometimes it won't shift completely into park, I had it decrease in speed from 70 on the highway to no more than 20 mph with over $400 in repairs just that time. I do not drive fast or deprive my car of regular maintenance. I have never had issues like this with any other vehicle.

Going to work on a city street car completely shut off. It blacked out. No hazards no lights and this was at 3:30 in the morning. And it's happening more and more. It happened to my husband on a busy street. All we can do is wait and try to start it until luckily it did. But before this started, the car kept on shutting off on me when I come to a stop. It's happened at least 6 times in the last 3 weeks. And today it stated on the dashboard that it was reducing its speed. What's next?! it's dangerous because I have my kids with me and I'm afraid someone might rear end me one day. Or if it completely blacks out on me on my way to work and I have no one to help me and I get stranded. I wish they would do a recall. I've seen online how it's been happening to a lot of people.

My car keeps reducing engine speed Chevy fixed it once now it's doing it again. I almost died on the freeway

- Douglasville, GA, USA

Driving at highway speeds car suddenly slowed down and reduced engine power popped up on the screen. The car wouldn't accelerate more than 20 mph. Luckily I was near the shoulder, but if I wasn't I could've easily gotten into an accident. This has happened to many other vehicles and needs to be looked into. It's extremely dangerous and could get someone killed.

Vehicle reduces power at random times. Without being signaled to do so. Has happened on the high way and streets

- Birmingham, AL, USA

The reduced engine power light is continuing to appear. I took it to my GM dealer and they told me they can't fix it. This is a safety concern. Dropping from 60 mph to 30 mph on the freeway/highway is not safe.
