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.
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.
I got P2138 code, i replaced the accelerator pedal on my cost because the dealer told me my car VIN is not include in the recall, the code keep coming back even after replacing the pedal. The problem it happen two time were I was driving on thruway "65 mph" the speed suddenly reduced to less than 30 mph which put me and the other drivers safety in dangerous situation
The contact owns a 2018 Chevrolet Malibu. The contact stated while driving approximately 65 MHP, the message "Engine Power Reduced" was displayed and the vehicle decelerated to 30 MPH. The contact stated that the speed would no longer exceed 30 MPH. The cause of the failure was not yet determined. The manufacturer was notified of the failure, but no assistance was offered. The local dealer was not contacted. The contact stated that the failure had also previously occurred but after taking the vehicle to the local dealer no cause of the failure was found. The failure mileage was 110,653.
My vehicle had the reduced power dash warning and check engine light on while I was driving down the interstate at 65 I lost my power speed reduced to 45 and my stability light came on as well it could have caused a serious accident had it been day time with traffic flying at 70 to 75 mph rear ending me I was able to get off the freeway safely last night when the incident occurred and safely make it to a parking lot there doesn’t seem to be a current recall on my car with my vin number at this time but it is a year and model that has known issues also the other issue is vehicle not registering into park even when I put shifter in park possibility is a loose shifter cable

While driving engine warning function low power. Would not accelerate above 20mph. Defective accelerator pedal assembly and sensor.
When put in park a message shows shift to park. I have to shove it into park before car would turn off. When stopping and making turns there is a sloushing sound (water) coming from the dash. I got both items fixed out of my own pocket because my extended warranty did not cover the air pocket but it did cover shift to park with a $50 deductible. I bought the car brand new so not sure why all these problems are happening. I know several other people with the same make and model having the same issues. These items need to be recalled and I would like to be reimbursed seeing the car is only 2 years old.
When put in park, vehicle does not recognize it is in park upon engine shut off and will not cut the electric signal to the car. Sometimes restarting the engine works but I have had to drive at least a block recently to get the electric signal to cut off. It has occured several times in my vehicle starting on december 24th 2020
Vehicle will not stay started will stop when ever even while driving. I haven’t driven the car in 8 months because it’s not safe.

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.
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.
Any time I've used my cruise control after my car had been serviced for the initial recall for the ECM over a year ago, I keep getting the 'reduced engine power' notification. This issue didn't begin until after the part was replaced. I've tried taking it to the dealership but they can't fix anything when the light isn't active. I've just stopped using the cruise control feature but I've been on the interstate while the reduced engine power notification comes on and my car slows.

I have a Chevy malibu 2018 and I commute to work 5 days a week 1 1/2 hours each way. During my commute without warning, a light came on indicating "engine power is reduced", the engine light, as well as the car slippery road sign. I have an appointment at mearle stone Chevrolet in hopes this known problem in the 2018 models gets fixed without paying out of pocket expenses since there has been a major safety concern on the highways not being able to accelerate like normal and having to build up speed by taking foot off accelerator. I cannot pass due to this and the engine is winding out like I need to change gears while the rpms are going up. I cannot get past 60mph even with accelerator all the way down. I am concerned with this model being made in april of 2018, and the Chevy malibu
When driving the car it will lose propulsion and power. At one point it almost shut off while driving on the highway. I took the car for inspection to Chevrolet dealer but I was told they will take weeks to find the exact issue. It also has a safety recall which wasn't performed during my appointment. I was told to come back if I see engine light without it they can't do much. I use my car every day to get to work and now I feel unsafe while driving it. My Chevrolet malibu is of the year 2018 with only 30k miles.
While driving, the message 'engine power is reduced' appeared. My car slowed down and I had to press really hard on the gas pedal to get back up to the speed I was at. It is said to be a defective electronic throttle control and accelerator pedal position sensor. This problem is common in many of the 2016-2018 Chevy malibu's. *bf

In may of 2020 I took my vehicle to a Chevrolet dealership in woodbridge,va for a ECM recall on my vehicle. After waiting for them to do the recall they stated nothing was wrong with my vehicle. From october to current my vehicle has been doing everything that was stated in the recall which lead me to believe that they never changed the part. My vehicle has shut off on me in the middle of the road almost causing me a accident and most days now it won't even start. I got my battery checked out and my battery tested 100% so I know that wasn't the problem. I called the dealership and they said I would have to pay to get that part replaced. Why should I have to pay when it's only been a couple of months since the recall, something isn't right. Please address this issue. -thank you!
The car says it's not in park when you shut it off. The fob seems to not respond sometimes. Sometimes it won't start and tells you to put it into the center console pocket but it still won't respond. It will say there is no fob in the car. I replaced the battery to make sure that wasn't the issue. Even with the fob in the car, it set off the alarm when I tried to start it. It took almost 5 minutes for it to respond to shut the alarm off but it would let me lock the doors while sitting inside it. So it registers the unlock and locking mechanism but nothing else sometimes.
