I was driving on a busy highway doing 70mph and a warning popped up on the dash and said engine power reduced and the car slowed down to 20mph. I almost got rear ended and had to pull over to the side of the road. This has also happened on a regular city street while going 40mph. This is very dangerous and needs to be corrected

Engine goes into power reduced mode regularly and prevents me from driving. It typically happens on the interstate, but has happened on city streets as well. Once I restart the car, I am able to drive again, but it is happens more and more often.

While operating my vehicle at approximately 50 mph on a busy highway I received a check engine light, traction control light and a warning that the engine power has been reduced. After all of those warnings my vehicle immediately slowed to 20 mph and would not speed up.

When driving my 2018 Chevy Malibu it stalls out while I'm driving reducing my speed to 20 mph when I'am on the freeway. As I continue to drive home I seen a notification that said power reduce system it happens very often and as a result of the stalling I was rear ended from the rear and it is very dangerous for me to continue driving this car.

I brought my car back in June. I've been having problems and thinking it's only my battery back to back. I've been stopped in the middle of the street where my car would just come off. One time jso police had to give my car a jump in the middle of the street at a left turning light. My car have stopped on beach blvd which was early in the day in the middle of the street. It got to the point where I had to get a portable jump starter. I looked into it & got brand new parts for so many things and one day it just wouldn't crank anymore. The lights and radio and everything come on and everything but it's not cranking anymore. I called many Chevrolet and was informed by that many 2018 Chevrolet Malibu's were recalled and no dealership in my town is trying to help me. The gas goes out the car very fast and everything. The car has been doing this for months but now it's finally to the point where it won't come on again. I'm only 19 and was just 18 when I brought my car on my own in the first place and now I'm stuck without anything to do.

The car us under 60,000 miles three years old and already breaking down. The air flow sensor out of self-test range, turbocharge engine underboost problems and mass air flow sensor performance is also problematic, making the car stop instantly and sporadically creating a high imminent danger of crashing and serious injuries. Luckily the car behind me was far enough to stop before rear-ending me. Had it been a semi-truck I don't think I would have been so lucky. These issues need to be immediately recalled and corrected!!!

I turned on my car and it said 'reduced engine power' on the screen and I could only accelerate up to 35mph. I was going up hill it felt like my car was barely moving. Turns felt much slower going uphill when driving in residential areas.

I was driving at approximately 55mph on a highway when the vehicle gave a warning of 'engine power is reduced'. my car quickly dropped to 20mph and I was unable accelerate. This happened while there was another vehicle behind me and I was scared I was going to be rear ended. I put my hazard lights on and parked my vehicle. I shut the vehicle off and turned it back on which allowed me to operate the vehicle again but only at a capacity of 40mph. I had the vehicle repaired later that day it needed something with an electronic throttle control and pedal sensor replaced. I also learned that this is an issue that GM is well aware of and feel that they need to recall vehicles affected by this issue. There's no reason a vehicle should be dropping to 20 mph unexpectedly on a highway.

While driving my engine and traction light came on and a sensor popped up that read 'engine power is reduced'. I was driving down the highway and my speed was reduced. I can't and could not speed up.

Car died in the middle of a busy intersection and wouldn't restart for approximately 2 minutes. Check engine light came on and reduced engine power on dash cluster was visible when it restarted. Dealership placed new battery & it went away for about a week then returned while driving in the 45 mph range, reduced engine power, then slow acceleration from a stop sign. Seems there have been multiple class action lawsuits for this issue with no recall in place at this time.

I started to accelerate and the check engine light came on and reduced engine power was on my information display and my car would not go over 30 mph. Just happened out of the blue. I have approximately 64,000 miles on my Malibu. This happened on a city street and not in heavy traffic, but could have been very dangerous, if I was on a highway. Then after I limped the car home I turned it off and turned it back on and it seemed normal, but check engine light is still on. I am getting rid of this car has had 5 recalls of various problems so far. On one occasion the dealership had my car for 2 weeks...trying to fix a problem with the accelerator.

The onstar system shocked my husband. The car won't start sometimes. The dash board reads different things when attempting to start car. The vehicle was parked in the yard with nothing plugged up to drain the battery.

While in motion the engine power is reduced then the car slowed to a speed of 20 mph. Upon starting M vehicle a week a later the engine reduction warning came on again. The throttle body was replaced now I'm being told it's the accelerator pedal position sensor. Why should I have to pay for this.
