While driving the car down the road a message displayed saying "engine power is reduced" and I could not drive the car over 20 miles per hour. This thankfully occurred while I was driving through a residential neighborhood so I was able to safely park my car. Through research there is a known defect with a faulty accelerator sensor that causes this. It is the first time this has happened since getting the vehicle brand new in 2017. This is scary because it was instant and I could have been on the freeway when this occurred.

I was driving on a road at 47 miles an hour. Out of no where, the car slowed all the way down to 15 miles an hour. On the dash board a notice flash stating "engine power reduced" I was barely able to navigate out of traffic without being hit. Then it happened again several hours later when I was on my way home, I had to constantly keep pulling over.

I own a 2017 Chevy Malibu lt. I was driving at around 60 mph on the highway, when suddenly I received a message on the dashboard stating, 'engine power is reduced'. I was in the middle lane and I had to frantically find a way to pull over to the right while the vehicle started slowing down to just about 20 mph. Fortunately, I was able to safely pull over. This is a very dangerous situation. I researched online, and found out that this exact thing has happened to many people who also own a Chevy Malibu 2016-2018. GM needs to seriously consider making this a recall.

It reduces power to the engine

My cars cut off and then display power steering reduces drive with caution this is scary because my son is with me in the car it's just cut off every time I stop or I'm driving

I was driving about 65 mph when my car displayed a warning on the dash that the power is reduced and the traction control and engine light came on simultaneously. The speed reduced to 20 and would not accelerate. Pulled off the highway and shut off the car. I restarted it after a minute and the traction light went off but the check engine light remained on. The car then drove at normal speed the rest of the way home. This is terrifying as I didn't have a shoulder to pull off and had to pull in someones driveway. Luckily nobody plowed into me. I am now afraid to drive my car anywhere

I purchased my 2017 Malibu from jud kuhn in SC, it had 40,000 miles when purchased. Week 2 I was at a stop light hit the gas to take off the vehicle wouldn't move so I hit the gas a little harder still nothing then suddenly it jerked and took off fast. I thought maybe my foot wasnt on the has right. The next day I got in the car to back out my drive way and it did it again the same exact way. The same day the engine light came on and onstar sent me a email about a emission issue. I called the car dealer told them about the acceleration issue and the engine light. No one called me back and the engine light went out. A few days later the light returned and I called again. This time they serviced it stating the car needed a computer update and charged me 100 dollars and stated they couldnt find the problem with acceleration and the update may have fixed it. Sunday Oct 11th I went to leave me house again and the car wouldn't move the same thing happened hit the gas wouldn'mtove then took off. I got out of the drive way onto the road and it did it again. At this point I'm sceptical about the dealer as well as the vehicle and I have children and am afraid that one day I will pull out infront of oncoming traffic and may be hit because of the acceleration issues. I'm calling the dealer again today

Recently I have a message appear on my display screen. While sitting at a red light of course the car shuts off but when the traffic light turns green and the car starts back, I get the message steering assist reduced. I've been seeing this message for a few weeks now. This morning on my way to work, once again the message appears and this time my doors unlocked & locked, the vehicle reduced speed and I drove it at that speed until I was able to merge off the highway. I pulled into a parking lot and turned the car off. I waited a few minutes and restarted the car. I was able to make it to work but constantly put the car in neutral or park when I got to a red traffic light. This really scared me while driving in heavy traffic. Several cars had to go around me due to reduced speed. I see several people with the same complaint. Got to be a recall. I have an appointment with a Chevy dealership on tomorrow and hopefully I'll get some answers. Praying whatever the problem is under warranty. I need answers!!!

While driving on highway check engine light came on and engine power reduxe light came on dash. Vehicle decelerated rapidly on major highway was almost rear ended by semi tractor triailer. Was able to turn car off and it went away. But has returned next day. I contacted GM 09/21/20 amd they stated they were aware of ongoing issues and I could bring it in to get looked at but would have to pay a diagnostic fee

Everytime I stop at a red light or brake the vehicle(when coming to a stop in traffic)the car completely cuts off.the alert steering assist is reduced, drive with care constantly comes on whenever there is an auto stop and the car restarts. The radio and air would also turn off when auto stop is activated. This turn off also causes the radio screen to go black for a short time until it restarts. Which is a big problem and dangerous when driving in traffic. The normal auto stop would be somewhat silent, but when it turns back on now it hisses and turns back on. I also hear something as if water is passing through pipes after and/or during auto stop sometimes. Lastly, last night(7/8/20)I attempted to turn on my car and back out of my driveway. The car turned on but the check engine light came on. It did not allow me to shift into any gears or accelerate. I noticed the lights that illuminate, D, R, L, etc. Was not illuminating at that time when I attempted to shift gears. I then turned the car off but it stated shift to park. Note the car was in park. After I let it sit in park for a while I tried restarting the car and it restarted. The car shifted in to gears and accelerated. Note: The car allowed me to move the shift in and out of gears but it was not catching. The stopping issue wit the steering reduced alert started about two weeks ago(around June 25,2020). Hearing the water sound began around the the beginning of March 2020. Lastly the shifting issue began last night,7/8/20. When driving on the highway I do the speed limit 60-70 mph. On the city streets I drive the speed limit ranging 25mph-40 mph.

Entered on-ramp to head South on I-93 and half-way up the ramp it happened again. The "reduce engine power light" came on and the speed dropped immediately. I couldn't turn around and go home, so I continued down the interstate going in and out of the breakdown lane to avoid upcoming traffic behind me. Immediately drove to dealership and dropped off vehicle. I have been working from home since March 15, 2020, so I probably put approximately 200 miles on the vehicle since the ECM was replaced. There is no rhyme or reason that this continues to happen. However, this is absolutely and totally unsafe and unacceptable!!! I'm thinking people have died because of this issue - it is so unsafe!!!! I am waiting to hear back from the dealership.

- Sanbornton, NH, USA

Drove 30 miles since the last time it was in the shop for this issue. Started my vehicle in the driveway and the "reduced engine power light" came on. So frustrating and a waste of time!! I immediately drove back to dealership for repair. A bunch of codes came up. They removed and replaced the ECM. Road tested for 45 miles before returning vehicle.

Cruising to work on I-93 in concord, nh traveling around 70 mph and it just lost power again!!! the "reduce engine power light" came on and vehicle would only go 25-30 mph. Thankfully there wasn't a vehicle behind me. I would have been "killed". dropped vehicle to Chevy dealer. They found P2127 for accelerator pedal position sensor failure, replaced gas pedal, cleared codes, road testes. Mileage 76,473. This is absolutely and totally unsafe and unacceptable. The vehicle is in the shop again for the fourth time, same issue. I will report each incident separately.

While driving in heavy interstate traffic my vehicle began to idle roughly and cut off twice in traffic. Once it crank fully it accelerated at a high rate of speed just barely missing the car in front of me. When I went to repair my vehicle I was told that this is a wide known issue with no recall in place. I could have lost my life that day.

- Pensacola, FL, USA

I was driving on the highway today going around 70 mph and my car displayed "reduced engine power" and immediately lost power and decelerated. It is not the first time that it has done this but it was the first time driving at that high rate of speed. The other times it has happened on city streets when I was going more than maybe 40 mph. Each time if I turn the car off and then wait a few seconds and start it again, the reduced engine power display is gone and I dont have anymore immediate issues with it, sometimes for days or weeks at a time. I have noticed online that several people have experienced something similar with their 2017 Chevrolet Malibu.

- Cincinnati, OH, USA

While driving 60mph on the highway, my car began beeping and displayed 'reduced engine power' on the screen. The traction light and engine light also came on. The cars speed was immediately reduced almost causing a serious accident as I was in the left lane on the highway with a semi behind and beside me. I was able to maneuver to the shoulder. I had to restart the car twice in order to be able drive it home. This was an absolutely terrifying situation. The check engine light is still on. Upon googling this issue, many people have had this problem and there has not been a recall! if my reaction time wasn't a fast as it was today, I would have been seriously hurt, or worse. GM needs to address this.

I was on a highway in Warren oh driving to work traveling at 65 mph in the left lane. A message appeared and said loss of engine power and the at went from 65 to 20 in 1 second. There were vehicles behind me and beside me. I was almost rear ended and when I tried to get over to the side of the road I was almost smashed by a semi. As well as that message it then stated steering assist inactive so it was then hard to turn my wheel as if there wasn't enough of a problem. Thank god I am ok but someone else may not be so lucky. There are numerous complaints that I see on the internet about this issue. How is there not a recall. GM should be responsible for these repairs. I just purchased this vehicle in Nov 2019.

Reduced engine power first time this happened I was making a U turn at slow speeds when my dash displayed ' reduced engine power' check engine light came on as well as traction control light. I pulled over turned my car off and back on a few mins later later lights went away and car drove fine. ( November 2019 ) second time was mid February 2020 I was driving about 40 mph when same thing happened. Dash lights came on reduced engine power came back on and car slowed down to less the 20 mph within seconds. Once again I had to pull over turned my car on/off about 3 times in 20 mins for light to go away and car drive normal again. Third time today 2/27/20 at maybe 10 mph my dash lit up once again check engine light did not go away this time. But car drove fine afterwords luckily it hasn't happened on highway speeds or with my daughter in the car. All this in the last 3 months I bought my car with 20 miles June 1st 2017 and currently has 38K miles. This definitely has to be fixed before it causes serious accidents !

I was driving straight at 47mph on a major street in denver and the check engine light came on. At the same time, the display read "engine power is reduced" and I lost all acceleration. My speed dropped to about 20mph very quickly (5 to 8 seconds). Luckily there was relatively light traffic. I pulled into an autozone that was at the next intersection and they read the error code P2138. Come to find out this shows an error with the throttle/pedal position censor. I got back in my car to drive home and within 30 seconds, the check engine light went off and my car ran like normal. I'm still very worried about this sensor however. When I looked this up online tonight, I came to find out this is a common problem yet Chevy has decided not to recall this part. Doing more research lead me to the class action lawsuit which has been by rothschild V. General Motors llc, case no. 1:19-cv-05240, in the U.S. district court for the eastern district of New York. From what I read, and knowing that I drive 35,000 miles per year for work, I believe this could be a huge if this were to happen when I'm doing 75+mph on the interstate. I urge the NHTSA to review this very dangerous situation carefully and strongly recommend you have Chevy do the right thing and get this part fixed and replaced to keep us drivers safe!!
