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.
2018 Chevrolet Malibu acceleration complaints
Page 4 of 5: complaints 71 to 100 of 114, newest first, as owners wrote them.
I was driving at highway speed when suddenly car decelerated to 20mph. The check engine light warning popped up along with a engine power reduced message. I was unable to accelerate at normal highway speeds even after turning off and restarting car.
Check engine light came on and my speed was instantly reduced as I was driving. Sometimes it goes off after turning off the ignition but I could be on the highway or city streets and it will occur, causing a sudden slower speed.
I was driving on a highway going about 50 MPH and I started to accelerate and as I hit 55 MPH I got an error message reading, 'engine power reduced' and the ABS light and engine light both lit up. I also could not accelerate any longer. I pulled over immediately turned off the car and waited about 3 minutes and turned the car back on, I did not get a message however the check engine light still was lit but not the ABS light. I drove to an autozone got he code read and it was p2138. I looked up online and it seems as if thousands also have this problem with 2016-2018 malibu's and cruzes. I'm also aware gm has had a lawsuit against them over this.
Check engine light, tracking light, steering wheel locks up , low engine and can't exceed 45 ~ 50 MPH all happens when in motion
While going highway speeds on my 2018 malibu, I received a notification on my dash that said my engine was losing power. After clearing the notification, my car dropped in MPH and I couldn't go faster than 60mph. After a minute or two after that, my MPH dropped again and I couldn't go faster than 25 MPH while my rpms were spiking at 4000. I took it to a mechanic who said the acceleration sensor is bad and I had to replace my accelerator and was forewarned that this is is going to happen again because it's a factory defect. I know I'm not the only one with this problem given there's a class action lawsuit already out there. But I wanted to add to the masses so chevy is forced to fix this issue before people get seriously hurt.
So many issues, car currently not starting. Codes were for brake booster and maf sensors, replaced both. Still won't start. Open recall emc, called dealership, they stated recall is free but since it won't start I have to pay 125 so they can hook it to computer. Shift to gear happens weekly, car will be in park. Stabiltrack came on a few times, but goes away. It tells me icy conditions on evan warm days, display will go black bu usually randomly comes on. The worst is the reduced engine mode. There is no rhyme or reason. I have been on the street doing about 35 MPH and it does it also on highway at high speeds with 4 kids in the car, terrifying and dangerous. I am sure I'm forgetting things I have just come to not feel safe or comfortable driving this car, local dealership is no help. Took a picture of one of the first time it happened but that was 20000 miles ago, haprns randomly and almost in clusters. I can go a month or 2 with nothing and then it's 2-4 times a day for a few days or weeks, and then stops.
Reduce power message appeared while in traffic reducing speed dramatically. Was not able to go more than 13 MPH in a 50mph zone.
My car randomly displayed a message on the dashboard that said "engine power reduced" traction light and check engine light appeared and it brought my speed limit to around 20 while I was on a busy street. I turned the car off and got the power back but has done it 3 more time in 2 days. Very scary with 2 babies in the car.
Taking my fianc to the airport so that he can report for duty and the vehicle abruptly comes to a speed of 20mph on the highway cause a vehicle behind me to come to a close contact with my car. Replaced sensor and pedal as instructed because I am fresh out of my warranty and a month later. The issue returned. I cannot afford to pay 200 to 500 every couple of weeks or mo the to fix this issue. Chevy is aware of this issue and has elected to do nothing. It has been reoccurring in2016 to 2018 vehicles.
We were driving on the freeway and the reduced power light, engine light and traction control light came on. The power was reduced and we pulled over, shut the car off and waited a few minutes. We started it again and the check engine light stays on, but we were able to gain speed to get back in traffic. This happened once a few weeks ago and twice today. It's very scary and dangerous. We were fortunate enough to be able to get off the road. If traffic would have been heavy it may not have turned out this way. This is my second malibu with this problem. We had it repaired in our 2016 malibu and the dealership split the cost of the repairs. This tells us they know this is a problem.
While driving, vehicle with randomly display error code saying 'engine power reduced'. When this happens, the car's speed reduces to ~25 MPH and it's incredibly hard to accelerate past that. This reduced engine power warning comes on frequently, and without warning. Sometimes it will go weeks without doing it, and sometimes it will do it multiple times a trip. Every time it happens, the engine light & traction control light comes on. The only thing that temporarily fixes the car is pulling over, turning the entire car off, then turning it back on. This obviously is very dangerous while driving with any traffic around you. Once I turn my car back on, the check engine light remains on (traction light turns off), and then eventually turns off by itself (granted it doesn't happen again soon after). After speaking to other chevy owners, I've learned this is very common & I've even been able to find posts on online forums regarding this issue.
After 2 months of having this car the check engine light would come on and after the stabilitrak light would come on which reduced the speed of the car . This would come on when I'm driving or even if I just crank the car up from it sitting over night . I got it tested and the shop doesn't know why it keeps coming on . The check engine lights reads that the throttle need to be changed but that's not the only issue . My boyfriend believes that the hub bearing needs to be fix but we don't know . The car does not pick up speed when the traction light is on . The traction light also reads 'engine power reduce ' before the light comes on . I just got this car and I'm now having to spend 1,000+ dollars on a car that's 'new' . None of the issues associated with my car has been recalled and I don't understand why .
The vehicle engine reduced power while on the highway causing abrupt drop in speed to lower than the speed limit almost causing an accident and a bumper to bumper collision.
Shift to park warning when exiting vehicle when the vehicle is in park and engine is off
I was driving the vehicle and all of a sudden the check engine light came on and the display read engine power reduced. I wasn't sure what that meant so I pulled over. I tried to pull off and I had no brakes. Apparently something in the braking system broke and my engine was destroyed. I talked with gm and they told me that it has happened before with this model car.
We had the ECM system recal fixed (reprogrammed) and it was ok, but now a couple months later its doing it again. While driving the traction light and the engine light come on and power and speed is reduced, without warning and won't allow acceleration. Usually on the highway. Very dangerous!
On the freeway going about 70mph.engine power reduced light came on. My speed dropped to 20mph. Very scary especially with a child in the car. Glad it was not heavy traffic. I went to autozone. (error code p2138)...I called the warranty department and it is not covered.
While driving down the street I got an alert on the dash indicating 'engine power reduced' check engine light and what I believe is the traction control light came on. Can't accelerate. Can't go more than 30 MPH. No open recalls in my vehicle, but seems a lot of people having same issue?
The recall ECM caused engine to stall as I was driving up a hill, I accelerated to make up for the delay and veered into a parked car causing my car to over turn on the hood. I was injured and car rendered totalled. This was my second accident. I was sidestepped on the highway causing damage to my entire side of vehicle. Also had near accidents on highway when car lost power due to ECM malfunction. (recall issue that was looked at but never resolved). I have photos available. I have asked various ddepartments at the dealership and gm financial for assistance with this issue but to no avail.
My car reduced its engine power and slowed down from 60 miles down to 20 miles while driving on the high way with a tank truck behind me. I have never been so scared in my life. The engine reduced its power three times now! I was told there was a recall on this and the issue was fixed but clearly it wasn't! I have children and I am terrified to drive my car now because of this!!!!!
While driving on the freeway at speeds of up to 80 MPH at random times the car will suddenly slow itself down to 20 MPH and the dash will message that engine power is reduced. It's a serious problem that is dangerous to not only the people in the vehicle but all other vehicles on the road also.
At a stop light, when light turned green, pressed accelerator, "engine power is reduced" messaged flashed, engine and traction lights came on. Unable to accelerate over 25mph, RPM would not go above 3. Recall maintenance for ECM was completed on 01/11/2020.
Low fuel, engine light, service stability track, shift to park lights come on. The low fuel light comes on first. The next day the engine light comes on sometimes it stays on then goes off. This happens when I'm driving. I've had all the recalls done. Ecm replaced. 2 weeks later the same thing. All dials go to zero. Slow take off after I've stopped at red light or stop sign. Is as if the transmission is going out. If I put on brakes they will throw me in the dash like I've crashed into something. When I take it dealership-no codes are found. Trying to turn car off, it says shift to park. It's already parked. I've taken it back to the dealership several times for this same problems-no codes. I've gotten a rental (for a week)so they can keep the car to try and recreate it- they can't. This car was bought new in august of 2018.chevy malibuls 4dr sdn black. The date below "when did this happen" outs the latest date.
Check engine light and reduced engine power vehicle won't accelerate on highway in traffic
While driving check engine light comes on and control panel says engine power reduced. The car slows down and you are not able to accelerate.this has happened numerous times since I have bought the car and typically happens while accelerating.
While in motion cars reduced engine power lights up on dashboard and car looses power while driving
Faulty accelerator position sensor. Part is suppose to last the life of the car. The car has 60000 miles on it. It throws the check engine light and reduces power to the vehicle at highway speeds. This is very dangerous as you cant accelerate to get out of traffic or to get across the lanes. You just have to coast to safety.
I just got a 2018 chevy malibu. I was driving home from work today and my car just stopped and a reduce engine power message flashed across my screen. I could have been killed when I car cut off in the middle of a busy street. I have just seen all of the messages about these issues and people coming out of hundreds of dollars to fix it. Chevy needs to do a recall on this issues sooner than later, this could be between life and death for someone.
I was driving down the interstate doing 74 miles an hour when all of a sudden the car jerked and started slowing down. The display screen showed a messaging saying engine power reduced. I pulled over on the shoulder because it wouldn't let me accelerate and had slowed the car down to 50 MPH. I sat there for a minute and was going to try to drive on the shoulder to the next exit. When I started the car the message was no longer there but the check engine light was still on. The car has done this more than 10 times since this day.
