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.

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.

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 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 ??!!??

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 daughter was driving and the engine power is reduced message appeared on her dashboard. Once it appeared she couldn’t go more than 20 miles an hour and this is dangerous.

Reduced power mode warning came on and 3 seconds later I went from 70mph to 10mph on a freeway and could only do about 10 from that point on, the accident that was avoided would have been deadly if I wasn’t in the right lane to immediately pull over Took it to the mechanic and he said that there’s a recall that the dealership REFUSES TO ACKNOWLEDGE even tho we got a reading of #n1-82188250-01 told the manufacturer and there fixing it Monday My question is why has this not been recalled?? I do not feel safe, I do not want this car I WANT THIS PROBLEM ACKNOWLEDGED by ppl who care and can do something, what is Chevy waiting for someone to die before this is addressed??? This is so criminal put a RECALL OUT

I am driving and all of a sudden car "reduces power" and won't let me go over 20 mph. Sometimes it dies completely even on the highway. Out if no where, it shows "Reduced Engine Power" on the dash and won't go over 20 mph. This has almost caused a few accidents with my baby in the backseat, too. This has happened several times

NHTSA ODI 11446468

Vehicle jerks when accelerating. Loses power. Usually will stop after turning the car off for a few minutes. Different engine codes have came up (camshaft position timer, air intake system) no one can seem to find the problem

A few days after I got my in October 2018 my car did not start! I pressed the push start and it turned on but wouldn’t “start.” It went back to normal shortly after that but then randomly “steering issues” started happening. THEN my car would LITERALLY STOP at lights and take a minute to turn back on. Or I would be trying to get speed and my CAR WOULD NOT GO. Do you know how unsafe that made me feel especially having a 5 year old and 2 year (when it happen in the last they where obviously 3 and a new born) but it was scary. The check engine light comes on and off. And TODAY MY CAR did what it do a here and there it shut off… and then on a BUSY road WOULD NOT GO. I had to sit and wait until my family could help push my 2 year old car off the busy road with my 2 babies in the car. It was horrible. Im paying so much for a car I CONSISTENTLY have issues with. Im scared to drive my own car. Now im being told my car needs a new battery, a weird part is needing to be replaced. I have had the same issues taken it to the shop and told everything is good. Oil changes kept up etc. everyone I know that has a Malibu has issues with their Malibu’s

Driving on I20 in heavy traffic all doing 75MPH the car lost all power.Although I had plenty of gas it did no good pumping the gas pedal .Fortunatly I was in the left lane and coasted to the shoulder before anyone collided with me. If I was in the right lane I am sure a collision would have occured as traffic would not have allowed me to get to the shoulder.After several hours I got towed 70 miles to the dealership.There was absolutely no warning of a problem prior to the incident. According to the dealership the fuel pump sensor shorted out and no gas could get to the engine.The car is still at the dealers as they have not gotten the backlogged part to repair the vehicle

Driving at a speed 55-65 engine power being reduced light comes on and vehicle slows to about 40 speed while engine light is on. It goes in and out like this for days then it does it again. Vehicle was repaired at Chevy dealer 3/18/21. Now it’s doing it again.

NHTSA ODI 11444485

For over two years now I have been getting a reduced engine power when I drive. The car becomes slow and it is very dangerous especially on the highway. I have almost crashed a couple of times due to this issue. Once I turn the car off and on it goes off but off late that no longer works for me. This has been constant and has made my car useless. I can’t even go anywhere with it. A recall needs to me done because this is heartless and painful. Spending much on a car that I can’t even drive anymore.

NHTSA ODI 11443725

Vehicle slows way down and loss of power. Engine power reduced. On heads up display. Seems to use alot of gas when this happens. I need to pull over and shut off car. Wait a bit and then restart. And get back on road. It did this 3 times in my commute to work. Also was snowing that morning and was slippery out so very dangerous almost was involved in an accident but luckily not. Seems to do this more in the colder Temps. It has happened however in summer also but not as often. I have read many complaints about this issue. I am not sure why GM has not figured this issue out yet. Very concerned.

The check engine light came on and after getting it diagnose I recieved a P1101 code indicating air mass flow problem. After replacing the sensor I later received an engine power reduce on the dashboard. I received that warning while driving on the interstate and my vehicle started reducing speed possibly causing an accident.
