While driving the speed suddenly reduced and brakes locked up on me. I was lucky enough to be able to veer to the left and get off the busy street without crashing into anyone or anything. When I stopped the car cut off and would not start back up even with a jump. This happened to me twice before and they did a recall on the same part. I need ot fixed again. I also had to replace the battery every time including this time.

While driving th vehicle the component that ruptured was the vehicles vacuum brake booster pump which connected directly to the engine. The ruptured caused shards of metal to be launched into the engine resulting in no brake power and needs an engine swap. There was a recall on this model vehicle for the Pedal sensor malfunction that results in the cars engine going into a reduced power mode abruptly and suddenly while driving. This malfunction has occurred on this vehicle and I was not aware of this vehicle models recall history but it stated that the recall was successfully closed out in 2020. I purchased my 2018 Chevy Malibu in the year 2021 and the issue still persist. I am not confident that the recall on this vehicle was either fully completed or successfully fixed before purchasing. The car is now at the dealer and the repair team explains the vehicle needs a new engine. I questioned about the pedal sensor malfunction and asked if it was possible that this malfunction sending the vehicle into a reduced power mode so suddenly could have effected or cause wear and tear on brake booster pump connected to the engine. The dealers repair team wasn-??t confident in saying it wasn-??t possible. This is likely a design issue and if a recall was completed and I was sold a vehicle uninformed of this potential issue but the malfunction still persisted I do not believe I should have to cover the full cost of repairs for this chain of events. This malfunctioned put me at danger and if it had occurred while my wife and 3 children were in the car it could have been life threatening not only to us but the other drivers around as well. With the engine reduced you can-??t accelerate and with the booster pump ruptures mid drive you lose all brake power. It is hard to understand the faulty design in this but I have read reviews that others have had the same issue so I do not believe I am alone in this.

car pauses after stopping at lights and stop signs and in stop-n-go traffic and won't go as soon as gas pedal is pressed. It hesitates then jerks forward once the gas is activated. Check engine warning is for stop/start transmission accumulator sensor! Cost to repair over $1300 and seems to be the same issue seen in thousands of 2018 malibu's that have been recalled"?? My car does not show an active recall??? Chevy rep Andrea at 1-800-222-1020 said sorry no recall for your car and to contact you with complaint" This issue almost caused my wife to have accidents after the car lurched forward after stopping. We were also beeped at many times as cars behind us were frustrated we could not move for 10-20 seconds after stopping!

Since I got the car, if I let it go in auto stop, it has a hard time accelerating when I push the gas. It has gotten worse and now it has a hard time accelerating in general. When I push the gas it sounds really loud like it-??s struggling to go. I realized this is a safety issue for me and others when my car wasn-??t going at the light of a busy intersection, or when I-??m getting onto a highway and my car isn-??t picking up speed. This makes it scary for people already on the highway as Iam causing them to brake unexpectedly. Every time my check engine light comes on I take it to the dealership. It-??s been taken in for repairs multiple times but this issue still keeps coming back.

Check engine light came on I ran diagnostic I bought at the store to get the codes come to find out class actions for wrongful death because company knew about it. As I also see hundreds of he same complaints here. My wife on [XXX] Baltimore MD at the merge. She went from 60mph to 35mph. Then the car shut off with zero control of steering. Once in neutral she slightly touch the brakes which let it start up. Thank God no one was killed we have 2 beautiful 6 n 7 yr old girls what would I tell them.

On Jan 22,2024 while driving on the interstate the speed was unexpectedly instantly reduced, the car would not accelerate over 60 mph and the service engine light came on, the car was safely driven off the highway then towed to the dealership. My safety as well as the safety of other drivers on the highway was at risk when the car suddenly decreased to 60 mph from 75 mph which could have caused a collision. The inspection at the dealership confirmed that the issue was the intercooler for turbo found moisture/oil frozen in charge air cooler causing restriction in induction system, and the part design has been updated to help prevent the issue from happening again. My issue is that if the part has been updated that means that GM is aware of the issue and should be responsible for the cost of the part or there should have been a recall on the part. The consumer should not have to be responsible for the cost of the part or the repair to the vehicle. It is unknown if the part was inspected by an insurance representative but it was inspected by the dealership where the car was purchased. There were no prior warnings, lights or lamps occurring before the date of the incident. I feel like Gm should cover the cost of the repair, the total cost should no fall on the consumer and the vehicle manufacturer should take responsibility for the defective part.

While I was driving, the entire accelerator pedal mechanism fell to the ground. My mechanic told me it is because the accelerator pedal mechanism is a bad design, including too small of a bolt, and I had to have it reattached to the car. The accelerator pedal functioned, but it was incredibly dangerous because it was on the floor and couldn't be practically used.

2018 Chevy Malibu over 5 times this happens since we bought it brand new it has "Reduced Engine Power" error come on and the car can't accelerate over 30 miles per hour. This is a continued problem all the time and very dangerous when we are on the tollway that has a 70-mph speed limit, and you can't get the car to go over 30 mph. This same problem happens on our 2017 Chevy Malibu that we bought brand new since we owned it too and I have already put in a complaint filed today! This is extremely dangerous and takes you a long time to get home when you can only go 30 mph or less because of the "Reduced Engine Power" Limit. GM needs to recall these Malibu's and fix the dangerous "Reduced Engine Power" error because it's dangerous to the driver in rush hour traffic and on the tollway traffic with no ability to go over 30 mph. All these Malibu's need to be fixed properly and its GM's responsibility to ensure safety for their customers lives.

The car continuously is throwing a code P2138 and a warning comes up on dash saying reduced engine power. This happened 6 times to me yesterday wherein I was traveling on 1 lane winding roads in my neighborhood so the speed drops from wherever it is down to 10mph instantly. On 1 lane roads in the area where I reside there-??s no safe place to pull over. This is extremely dangerous and a massive safety hazard and risk to my life!

- Bayville, NY, USA

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

- Buffalo, NY, USA

Suddenly loss of power at cruising speeds. Trouble with acceleration and loss of power. Unresponsiveness from the engine. The Check Engine Light illuminate, OBD2 call for code P2138. The speed stuck at 30 m/h on the 65 m/h thruway which cause unsafe situation for me and other drivers on the road. When googling this issue on the internet, reviews show it is common problem in this model. GM refuses to fix this issue at their cost because "according to the VIN number of my car, it is not included in the recall list" which it does not make sense.

- Buffalo, NY, USA

Was driving to work when suddenly my check engine light comes on and I get a warning reading -??reduce power to engine-?? could feel the power literally reduce. Car won-??t go pass 30MPH could hear the engine trying to accelerate but struggling too. This is the second time it happens, have noticed other complain about this on going issue with 2016-2018 models

- Arlington, VA, USA

I keep getting a reoccurring message saying Engine Speed reduced, I can be driving going 60+MPH and randomly My car speed is reduced. This is becoming a safety issue as i have noticed this is a ongoing issue wit the 2016-2018 Chevy Malibu's.

- Abingdon, MD, USA

As I was driving I was addressed with a speed reduction warning and it followed with a very abrupt problem with speed as it was reduced drastically and almost getting rear-ended in the process I was able to pull over but very unsafely and without warning

- Belleville, MI, USA

What component or system failed or malfunctioned, and is it available for inspection upon request" A defect in the cam shaft solenoids causes a notice that "Engine Power is Reduced." At that point, the engine begins to struggle to accelerate from a stop, and from increasing speed while on the highway. How was your safety or the safety of others put at risk? The unpredictability of the defect and its affect while driving poses a large threat to safety, particularly on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealership service rep not only confirmed the defect, but also confirmed that the issue persists across multiple GM models yet no recall exists. Again, this is a KNOWN defect with GM engines, as confirmed directly by the dealership. Despite this, no remedy was offered, I was told it's neither covered by my manufacturer's warranty or recall. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. I was given a video explanation of the issue and also told directly of these persistence of the defect across multiple lines. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No warning prior to the failure. The defect and "Engine Power Reduced" message both first presented in March of 2022, less than a year into my ownership of the car -- and while my car was still under its 60,000 mile warranty.

I received a recall letter in 2019 for N192221960. The engine control module software needed to be updated. I have taken my car to the Moran chevy dealership on Gratiot perhaps 3 times before. I was driving yesterday, Oct 4th and my car did the same thing again: Reduced engine power while I was on the freeway. It would not allow me to accelerate past 40 mph very dangerous. They informed me that the repair would not be covered, which was surprising to me, because I thought with that frequency it would be. Each time they told me it was something different. This time I am being told that the price is $862 ECM needed work, and oxygen sensor and fuel injector services. I then received a call letting me know that the price was reduced to $693 and that the ECM was updated already (after I had called letting them know I called GM direct about the recall and was waiting to hear back).
