The vehicle was sent into the shop for repair four times and I continue to get a shift to park alert on dashboard after the repairs and warranty has passed I was asked to pay for the repairs when the dealership has serviced the car for over a week each time stating they couldn’t find the repair light I have contacted gm about the issue this is an act of consumer abuse I would like to be contacted on this matter

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.

there is a issue with the chevy mailubu where a message will pop up on the dash and say engine power reduced which will significantly slow down the speed of the car and is impossible to keep up with traffic as someone who has to use the expressway everyday with a toddler in the car this is a big issue also im wondering why this isnt a recall on the the malibu because i know three other people with the same issue and we all have different year cars. chevy service team said the issue was from a pcv valve that will cause the exhaust to clog up.

Driving at highway speed and the speed decreased to 20 mph engine power reduced along with engine light came on extremely unsafe. Purchased Dec 10, 2018 39,000 miles . Kids and myself could’ve been hurt.

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.

The harness and shifter solenoid went bad in my car. When I was on the highway, it stalled causing me to have to pull over onside the road. I nearly got hit in the rear by an 18-wheeler. There was an TSB on the make, model, and year of the car, but GM did not inform their customers of the issue and the dangerous situation one could be in if the car decided to malfunction in the middle of traffic. I was almost rear-ended from behind by an 18-wheeler while on the highway going 60 miles per hour. I also was stranded on the side of the road because they said they could not send anyone out. Malcolm Cunningham Chevrolet, a local Chevy dealer is aware of the issues with the vehicles, but when I bought my vehicle into the shop to get fixed, they lied and said I had wasted something in my car. They provided no pictures of the spills or pictures of the parts with the contamination that they claimed it had on it. The only person that inspected my car was Logan and the other technicians at Malcolm Cunningham Chevrolet in Augusta, Georgia. No, there was no warning lights indicating my harness and solenoid needed to be checked.

While driving o Leo noticed temp gauge going up. Pulled into a parking area. All my antifreeze had drained through a hole in the lower radiator hose. It had worn through because it was against a pully.

While driving at 55 miles my vehicle displayed engine speed reduced on the dashboard. My vehicle slowed down to only 20 miles in the middle of traffic And wouldn’t pick of speed.I had to put my hazard’s lights on and get to the side of the road as quickly as possible. I turn the car off than turned it back on same thing on dash engine powered reduced. I haven't took the car to the dealership yet

When the check engine light initially comes on, the car will go into "reduced engine power mode" which will decrease the power and speed of the car, forcing me to pull over and turn the car off and restart. This is a hazard to myself and other drivers especially when on the highway, driving at higher speeds. There has been an investigation in to GM where it was found that a few other models have this issue. This happens every time I have something repaired and the light comes back on, which has been twice in the past month. The first time this happened, I had the repair done and it was fine for a while. After the car has been off for a while and the light is still on when I start my car, for the most part the car is no longer in this mode, but it can come back on at any time.

We have had this car since 2020 & frequently the "reduced engine power" warning comes on & the car will not/or very slowly accellortate. Along with the engine light on.We have hooked it up to a computer many times but nothing solves the issue. Lately it has been staying on constantly. Huge safety risk as my two children are in the car daily & we do take main roads/highways! When this comes on, the car will not remote start as well, also this is random in doing so, it has came on when I 1st start the car in the morning, while driving at 35mph, stopped at a light, or turn on any time I turn the car on. Doing some research and many others have had issues as well as their engines giving out at 60,000 milles (ours is at 57,000) & nothing resolved for them either. This is a huge safety issue and needs recalled. Us malibu owners should not have to pay to get this looked at constantly nor worry about owing on a car that could give out at any given time. We keep maintenance up on our car and this is the only constant issue we have that cannot be fixed.

My car always go in engine power reduce mode.

The vacuum pump on my vehicle has gone out for the 3rd time in 2.5 years. This creates a safety issue as that the brakes stop working and it takes an extreme amount of pressure for the car to stop. This has occurred once on the freeway and twice in heavy traffic areas. This could cause an accident and potentially seriously hurt or kill someone. This has occurred once before the engine was replaced and twice since it's been replaced.

Shift to park
Other or unspecified, Feb 11, 2022
When the car shuts off at a red light and starts back up after u take your foot off the break, it has a stalling problem. Sitting at a light, the radio was still playing. Once it was time to drive and I took my foot off the break, the car was stuck. I had to turn the car off and turn it back on in order to drive it. That is very dangerous because I was in the middle of traffic. If the car behind me suddenly moved over the car behind them could have hit me from the back, I have a 5 year old in the backseat. This should be a recall problem. Other 2018 chevys have this problem as well but my model for some reason is not on the recall list.

As I was driving down the highway at 60 mph the road was clear at the time of any debris my car suddenly had two lights on the dashboard. On the left was the traction control light and the right side was the engine light. On my computer display was the words “reduced engine speed”. My car suddenly slowed from 60 to about 30 mph in a matter of seconds. It was like I had slammed my brakes. This all happened simultaneously I attempted to pull over safety and turn the car off and restart it. The lights remained on. My car was not able to get over 27 mph There was no warning what so ever If anyone would have been behind me I would have been rear ended At this time I took it to a mechanic who put it on the computer it was coded at the pedal position sensor. He was able to save the code, clear it so I was able to drive the car and advised to drive it locally for a while in case it would do it again as it is unsafe. The closest Chevy dealer is over an hour away from my town and at the time of day it was not safe to drive the car to the dealership for confirmation.
Vehicle speed control, Jan 30, 2022
Vehicle continually throws reduced engine power code which includes while traveling at high speeds and winter weather. Vehicle resets once powered off to throw a code sometimes again immediately or within a short period of time rendering the vehicle virtually unusable. Difficult to get to a safe spot to turn vehicle off to attempt to re-set. This puts occupants in danger of being rear ended, stuck in snow/mud or hit from behind while pulled over trying to reset vehicle. This has been an ongoing problem since purchasing the car new. Was fixed under warrant once. Fix didn’t last long and have continuously had issues

I was driving on a crowded city street in St. Louis and my car suddenly reduced power and I saw a message on my dash that said Engine Power Reduced! I could not go faster than 15 miles an hour and had to pull into a gas station. I restarted my car and still had the message. I restarted again and the check engine light was still on, but I was able to drive at a normal speed. My concern is that I was a short distance from getting on a busy interstate highway and it could have happened while I was on the highway and could have been struck by a car.

My 2018 Chevy Malibu has been working fine then all of a sudden the warning light came on and the message warning light read ENGINE POWER REDUCED While I was driving on the freeway at 60 mph dropping my speed to 25mph instincts told me to pull over, so I did! Then I tried to drive again still no power it was like a strong pullback! So I again pulled over and turned my car engine off! Let it sit a few hours before driving up to local automotive parts store to use the ODII code reader and it read the code P2138 Throttle/ Pedal Position Sensor Correlation The part to order is $120.00 I am not able to get it today so I googythe problem and found out that this is a possible RECALL ??!!??

Driving on my way to work and the check engine light came on with the traction control light. A message was displayed that said the engine’s power was reduced.. My speed also decreased to about 20-25 MPH and it was hard trying to get it back about that without the car sounding all funny.
