Problem has huge accident potential. *driving on the highway in moderately heavy traffic. *traveling at a 65-70 mph to keep up with the flow of traffic, I began receiving "engine power is reduced" message on my info screen. * the engine light comes on (and I immediately start counting how much time and money this will cost me). * there is a slight jerk/pull of the car where it immediately starts a drastic reduction in speed down to 20-30 mph. * I've had to pull to the side of the road to stop the car (I pray I am able to do this safely). *eventually, I found that by shutting the engine off completely for several minutes, the car somehow "resets" and drives normally. * occasionally, the engine light would go away immediately upon re-ignition. Other times the engine light went off after a couple day. * this happened several times during within a (1) hour commute to work.

The day before the car's dashboard said that the car's power assist was turning off. The next morning as I was going 75 miles per hour on the highway the car said that engine was reducing power and speed reduced to 45 mph. The check engine light suddenly went on and it was a very dangerous situation that could have killed me.

When I put the vehicle in park and try to shut off the engine, the engine will not shut off. It keeps running. It appears that the vehicle does not know it is in park. The vehicle is stationary but keeps on running.

It's amazing me reading all the complaints about this issue and GM hasn't issues a recall. However, I purchased a 2016 Chevy Malibu used about a year ago. Within the year, I've had my acceleration pedal be faulty, my car speed will drastically reduce from 60-70mph to 20-25mph which as I'm sure everyone knows is a safety hazard. Then less than 2 weeks later, the same thing happened but this time it was the alternator. Now not even 2 months later, my stop/start is malfunctioning. If I brake and the car turns off, my 'start' function does not start! I have to shift the car to park, turn the car on, then shift back to drive. All of which is dangerous! obviously, these complaints are not being read or are not being taken serious because I just read multiple complaints similar to this. On top of it all, because of everything I don't feel safe driving a car I paid for! and none of these issues are not my doing yet I'm the one in the dealership paying for it.

When I press the gas it hesitate to move forward and also my battery sensory has gone out. My car is only 4 years old I believe it has something to do with it being an eco which has caused major issues to my transmission and other parts of my car.

I purchased 2016 Malibu 10/2016 and after having the car for 6months the check engine/reduce speed lights starting coming on. I have taken it back over 20times and the issues was never fixed. I ask could they just replace the call since they are not able to fixed it. So, and still having this issues. GM extended the recall and I took it back in yesterday March 18, 2020. I was told that my car was fixed and to pick it up. So, I get there didn't make it out the lot. So, I return back to the service desk and I was told my transmission is going out. So I ask why this isn't on my service sheet I was informed that it was wiped out and that I had to request it. Putting me back in danger. This has been a headache. I file a lemon law complaint and they offer my 4500 and I owe 18,000 on a car that have been giving me issues from the day one. GM offering to settle out for 4500 is admitting fought

My car has been in and out the shop since I brought it brand new 0 miles for some type of engine related failure, sensors etc. My warranty has expired and now I am forced to pay out of pocket for maintence.

I was driving on the I-10 West highway at 70mph when all of a sudden a engine power reduced message came across the screen & due to the loss of acceleration I was almost rear ended by an 18 wheeler because I couldn't pull over to the side of the road fast enough...also, on some days when I start my car it doesn't make any noise so therefore the radio will not work, the signal light sounds doesn't work, nor does the seatbelt sounds work.

- Sunset, LA, USA

The car was driving at a high speed and then suddenly slowed down dramatically. An error code, along with the check engine light, came on starting reduced engine speed. The car is not able to speed up at all. This has happened several times. While driving on the freeway, which is very dangerous.

- Conroe, TX, USA

While driving on the freeway or the streets the vehicle looses power. A dashboard light comes on along with the check engine light and the dashboard says engine power is reduced. This causes the car to drop speed and lose power. It really unsafe as twice I've almost been rear ended.

- Houston, TX, USA

Incident has happened twice while driving on highway. Engine light came on, then received an error message of "engine power reduced". engine power and acceleration was reduced dramatically. Luckily there were no cars behind me or I may have been rear ended and involved in an accident. I pulled off on shoulder and turned car off and then turned car back on and engine power and acceleration was restored. Engine light remained on though.

I was driving on the highway, speed limit was 70mph I was going that speed then out of nowhere I got the check engine light and a notice on my dash appeared as 'engine power reduced' and my speed drastically declined I was almost rear ended by a semi truck, I had people in the back of my car and with an impact from a trailer we could have been seriously hurt or even killed. This a reoccurring proble with Malibu's from the year 2016-2019 GM knows about the issue but has done nothing to resolve it. This issue not only puts the driver of the vehicle in harm but others around as well. The problem is the throttle body response sensor which is about a $300-$500 fix which is not an cheap fix. They need to be held responsible for this because one day this could happen to anybody with this type of car and it can kill someone.

When driving the vehicle first the engine light came on and I got a diagnostics it was the mass air flow sensor code coming up. I had the thotle cleaned.... the engine light went off 2 daya later. Then I was driving on the hwy and the engine light came on along with the message engine reduce power. I pulled over shut the car off for 10 seconds, start it again and drive it. It does it on a daily now. And im tired of it this is a brand new car. I got it at 28,000 miles it is now at 53,000 miles. Chevrolet know that this problem is going on with many of the mailibus they need to fix it. I just spent 1,100 on this car for the repairs
