I was going 70mph on the highway, when I got a sudden alarm from the car saying "reduced power". The car would not accelerate and started slowing rapidly, almost resulting in a collision. The car would not go more than 20mph. I had to pull off to the shoulder, restart the car several times, and then was able to get the power to come back, but the check engine light remained on.

Error message on dash "shift to park". The car will not shut off completely with message on. I did some research, and it seems to be happening with a lot of Malibus and GMs. This is the second time it happens on my 2017 Chevrolet Malibu. My car is still fairly new with only 35k miles. The first time warranty covered it (shifter was replaced), but I'm not so sure if they will cover this second time. This is a manufacturer error and we should not have to pay the price every time this happens.

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.

Power engine reduced indicator warning across screen- now it will not even run 20 miles without bogging down to 20mph with no warning- their is a recall on it it was and always is in motion when this occurs. First happened at 30,000 miles - continued to happen maybe once or twice every few months- now happens every time the vehicle is ran! I've had the car since March 2018 it now has 100000 miles on it and only getting worse!!

- Hillsboro, WV, USA

When I put the transmission in park, the indicator screen on the dash notifies me to put gear in park. I'm able to shut down the engine but not turn off the electrical system which ends up draining the battery. The gear is in park, but a switch in the steering column isn't operating properly.

Reduced engine power warning 12/29/20 plus numerous occurrences in 2019 while driving on the highway; vehicle slows to 40mph without warning shift to park warning when vehicle already in park, can't shut off vehicle until it recognizes park, often taking upwards of 10 minutes of repeated shifting stabilitrack sensor warning and loss of cruise control, at highway speeds

- Osseo, MN, USA

Dash warning says action required....shift to park. But the car is already in park. Car will not shut off til you get it in park. Sometimes need to start and restart car a dozen times to get it to stop the error. This is a known problem with late model Malibu's. tsb # 19-na-206. Repair cost approximately $300. This happens at random times, making the vehicle unreliable. Need to do a recall!

- Brillion, WI, USA

Vehicle will shut down after auto stop enabled when car comes to complete stop at lights, intersections, etc. Vehicle will also shut down while driving. Stalitrak warning blinks but the electrical power inside doesn't always shut down. Car will start back up once you quickly put the vehicle in park, shut it off and then turn it back on. Sometimes it takes 3-5 times to get it started back up. Battery has been changed and sensor replaced but it still hasn't fixed the issue. Severely uncomfortable driving the car anywhere.

I was on the eway and I was going 80mph in the left lane, and my car jerked to decelerate to 20mph. The message said, 'engine power reduced'.

- Midlothian, IL, USA

About 6 months ago, I was driving in the interstate going about 70 mph, when my vehicle dropped its speed to 20 mph advising of ' reduced engine power ', the speed did not decrease which caused a hault & jerk. Which could have turned fatal if there was a vehicle behind me. October 30th, I was driving about 30mph in a residential area when I approached a stop sign and my vehicle suddenly lost power, after about 3 minutes I was able to start the vehicle and drive to the dealership. The battery and a sensor had been replaced. Exactly two weeks later, I was driving on the street around 25-30mph, approached a stop again and car powered off.. immediately taken to dealership and they could not identify the problem. This is a huge safety hazard, I do not drive on the highway out of fear that the car may shut off. I've been to authorized dealerships & had the transmission checked out by certified transmissions shops and can't source the problem

- Stone Mountain, GA, USA

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.

- Chicago, IL, USA

Vehicle would indicate/notify to shift to park even though vehicle indeed in was in park not allowing you to complete turn car off. Car would remain in ancillary mode.

- Blue Island, IL, USA

My 2017 Malibu has 65,000 miles on it. In the course of three days a warning kept popping up every time I came to a stop the car engine would turn off for a second and then turned back on with a warning that stated service stability track, driver assisted steering not engaged. Today I came to a stoplight and the engine completely died leaving me stranded there for about 15 minutes until I was finally able to get it started again and moving. I had to put the car in manual mode to get it to drive. I am awaiting the estimate from the dealership to see what it would cost to fix this. I have read scores of other reports of the same thing happening on these cars. To the point where some people are driving and it stops. This is a serious dangerous problem and it needs to be addressed by General Motors.

- Cincinnati, OH, USA

Driving down the interstate (with my family) at 70mph and loose power. Display shows "engine power reduced" just about got rear ended by a semi due to power loss. Had to get over to the shoulder while dodging traffic from behind me. Very dangerous. Needs to be corrected and covered by GM.

- Fairfield, IL, USA

After putting my 2017 Chevy Malibu into park, I received a "shift to park" message on the dash. The car would not fully turn off. It stayed in auxillary power mode. Doors would not lock, emergency lights stay on and had a beeping sound. The problem was not resolving itself irregardless of how many times I turned it off and on. The failure mileage was approximately 8,400. (yes, the mileage is 8,400. This is not a typo.) the vehicle was taken to martin Chevrolet, located at: 23505 hawthorne boulevard, torrance California, 90505. The service representative said this is a recurring problem and they have seen it multiple times. (it is a tranmission control assembly failure). I asked if it was a design flaw and he concurred. He said there was no recall at his time but they are expecting one. I spent $550 to have the replacement done. General Motors needs to declare a recall and refund my money. A two year old car with 8,400 miles should not be incurring major expenses for faulty components.
