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.

As I'm driving down the highway, trying to accelerate, a reduced engine power light comes on and my car will slow down to 20 mph. I have to shut my car off to get it to accelerate. It is doing this on a regular basis now.

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.

Car is saying 'engine power reduced'. car will not get up to speed like normal. Did have extremely heavy snowfall yesterday 02/16/2021 when it started saying this on the cluster

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!!

I was driving on the street when my engine power is reduced notification came up on my dash board. My engine light also came on. I was driving about 45mph when the light came on and it reduced my speed to 20mph. I was able to drive it home at the 20mph speed. I parked it overnight and checked on it the next morning. When starting my car the next day the engine power is reduced light was still on. I was looking online and others are having the same issue. What is going on. I need help

II bought my 2017 Chevrolet Malibu ls in August of 2017, in January of 2018 my first engine light warning came on with message "shift to park" came on when the car was already in park. I moved to denver, co in June of 2018, during my long while driving through the rockies the check engine light came on showing "stability track issues. In November 2018 while my family was driving home in a snow storm yet another engine light showing "engine powewr reduced" the car went from a 45 mph drive on the freeway because of heavy snow to almost 20 mph too slow for freeway speeds even in snow. I took it to the Chevy dealership they said it was a dirty speed sensor. While driving on the highway at 70 mph I was reaching the end of the freeway when the car completely shut off, I reacted by hitting my brakes but the pedal was hard as a rock, I looked up and I was fastly approaching an intersection so I used the emergency brake got on the riight dirt shoulder, and was able to slow it down to about 35 mph before reaching the intersection where I took a sharp right turn to avoid hitiing cars in front of me and spun out. The car ishowed a message "no remote detected: It would crank but not start. Being that the car warrenty was already expired I had it towed to a local mechanics shop where they discovered a code reading "brake booster sensor" they discovered a shattered vacuum pump. I got it replaced with a new one as well as the brake sensor. I still haven't been able to start it. Because of covid-19 and my financial situation I have not taken it to a dealership. I am saving to have it towed there and hopefully repairing it but I'm sure it's not going to be wallet friendly. We were excited when we bought our first new car it didn't last long. Now hopefully a recall and some justice for us hard working people that want only a reliable car with no hidden repair surprises.

The vehicle has shut off more than 5 times while driving requiring a tow and work done to the vehicle. The alternator, battery, and sensors have been replaced but the vehicle still turns off while driving.

When driving my car, it suddenly stops in the middle of the freeway and displays a 'loss engine power code'. I noticed that quite a bit of other Malibu owners have been having this same issue

Reduced speed engine problem will reduce speed while driving

- Oxnard, CA, 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

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.

- Ypsilanti, MI, 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.
