On 3 occasions, my vehicle has displayed the message -€œEngine Power is Reduced.-€ It has 83, 990 miles. I took it to the dealership to have them check it out, but I was told they couldn-€™t check it because the check engine light was no longer on. This is a problem because the warning will come on, then the check engine light turns off after the car has been turn off. The Chevy dealership says there is a three day wait for them to conduct a diagnostic, but what are the chances the check engine light will remain on? After having gone through this process on three separate occasions, the check engine light hasn-€™t appeared the next day. I have read about how others may be experiencing this problem and they do not have some resolution to this kind of problem. My wife generally drives this car, so I fear for her as she travels to and from work.

Engine power reduced notification came on the dashboard and car deaccelerated down to less than 25 miles an hour on the highway on multiple occasions. On the last occasion about 2 months ago the notification came on again, the car stalled and would not start up again. This was in ongoing traffic and I could have been seriously injured if people behind me were unable to stop in time. I sat in the middle of traffic for 45 minutes until fire and rescue came and pushed my car out of the road and onto the shoulder until the tow truck came.

Then when I try to press on the gas peddle it will go slow but my peddle power goes to a 4. The dealership said it was my tire speed sensors so I got them replaced all to STILL have the same problem. It will also read power stirring not available & shift to park even tho I-€™m already in park.

I-€™ve brought the car in for the same thing -€œengine power reduced -€œ and they never were able to fix has been going on since February of 2019. codes related to the engine power reduced still occurred and are occurring on my vehicle, reported it to Gm ( have the emails) they offer me $2500 for a new car but won-€™t put it towards fixing this car, as it-€™s not a guaranteed fix as the vehicle has been brought in over 4-5 times for the same engine power reduced and never fixed it. I received a letter from GM regarding they will cover anything to do with -€œengine power reduced -€œ at no charge and now they won-€™t fix it. The last email gm said to report it to the dealership giving me the run around. This is one of MANY almost got in an accident today on the highway cause I was going 70 and it dropped to 40 out of no where of course with the engine power reduced message. I need help, please. I been going on since I bought the vehicle in 2019. Gm is doing nothing but taken advantage of for years

Warning: Reduced speed, car stalled in the middle of traffic. Took to dealer ship and they charged me $279 and said it was the battery, from the looks of everyone else-€™s complaint, which we have the same complaint, I got ripped off. I deserve a refund and we all deserve our cars serviced.

Experienced electrical issues and engine issues since car was purchased in 2019. The car will stall randomly if stopped at a light or moving slowly in traffic. The breaks also skip when slowing down, I taken by break check and they advised the breaks where good, just had them done 2 years ago, max. I had the batteries replaced twice in the last 2 years, there is no faulty in the battery. Right now my car is not working at all, the breaks became stiff while driving, constant error saying "Reduced Engine Power". The car would turn over but it will not hold. I took it to my local mechanic, who advised he replaced all parts that could be the issue but the car still will not run right. He states it's and Engine or computer issue. There are a few recalls already issued by chevy, my car was made in July of 2017, and the issues described is the exact same issues I'm having.

Vehicle won't start and dealership determine it was the battery. Replaced battery now vehicle shuts off completely when making a complete stop. Vehicle will maintain in normal operation if shifted into neutral upon stopping. The vehicle was taken to Harper Motor Dealership where it was determine the starter was bad. After replacing the starter the next the problem remained. Took the vehicle back the next day and after three days it was determined a GM expert was needed to determine the issue. One week later and a proposed bill of $3500 to repair I decided to write this down. This appears to be a major safety issue that could cause harm or death. This has been an issue since 2013 in the Malibu and the issue has still not been corrected.

Reduced engine power occurs while driving and will indicate a traction control issue and the check engine light will engage. The first time it happened, it was during a snowstorm on 2/24/2022, but it has occurred two other times while driving on a highway on sunny days (3/3/2022 and 3/8/2022) with no snow on the ground, road completely dry. Car speed dropped from approximately 55-60 mph to 20. I have to pull the car off the road, turn it off, and let set for at least one minute turned off before it will have engine power restored. Code for car was checked, and it was P2138, throttle/pedal position sensor switch.
