While im driving the stabilitrack warning will pop on then the engine light & immediately after my car will jerk to a almost stop. 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 “engine power reduced “ 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 “engine power reduced “ 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.

Other or unspecified, Engine, Feb 22, 2022
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.
Vehicle speed control, Engine, Jan 24, 2022
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.

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
