Reduced engine power message pops up when I’m driving at 45 or lower speed. First time this happened was about 4 months ago, and couldn’t drive faster than 30 mph. After starting my vehicle a couple of times the message goes away. This reduced engine power message is almost a daily thing, but now it doesn’t affect my speed anymore, I can go at 65 mph and even with that warning light on.

SHIFT TO PARK ISSUE
Oct 03, 2025
The car is saying “shift to park” on the dash panel as if the car is not in park. Sometimes this continues to read to the point it will not let you shut the car off and then you can’t get out of the car. This is a safety concern as well as an issue with the car wanting to continuously run.

car not recognizing it is in park. Displays "shift to park" on information screen.

1. This case refers to a 2018 Chevy Malibu. In October 2021, the (gear shift) transmission control system was found faulty and was replaced with an N-CONTROL in the gear shift. Again, in September 2025, the same issue happened, this time replacing the N-CONTROL again as well as the N-HARNESS. Yes, can be available upon an inspection request. 2. This component directly affects how the car recognizes when it is in Park. When it malfunctions, it can confuse the vehicle’s electronic systems and potentially prevent the car from shutting down properly, engaging the shift lock, or starting safely. This creates a safety risk for both me the driver and others around my vehicle. Since this is a recurring issue as well as other 18 Chevy Malibu's I don’t believe this is normal wear and tear. Having to replace the same system twice in such a short period suggests a recurring failure or a design flaw. 3. Yes, the problem has been confirmed twice by Chevrolet dealerships on both occurrences. 4. Yes, the component was inspected by two Chevrolet dealerships during both occurrences. 5. Had warning message "shift into park" both times in the month the car was taken in to be inspected.

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.

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

Car was driving on major highway when the alarm went off and check engine light came on saying reduced engine power. Car dropped down to 20mph at roughly 2,000rpm's on a major interstate. No prior indicators and mechanic said one of the sensors was the issue. Reading up there is apparently a class action lawsuit with GM and nothing has been done about it. NHTSA needs to address this matter ASAP.

Vehicle continually throws reduced engine power code which includes while traveling at high speeds and winter weather. Vehicle resets once powered off to throw a code sometimes again immediately or within a short period of time rendering the vehicle virtually unusable. Difficult to get to a safe spot to turn vehicle off to attempt to re-set. This puts occupants in danger of being rear ended, stuck in snow/mud or hit from behind while pulled over trying to reset vehicle. This has been an ongoing problem since purchasing the car new. Was fixed under warrant once. Fix didn’t last long and have continuously had issues

Hello, I own a 2018 Chevy Malibu. I previously had the recall repair completed for ECM Malfunction. Unfortunately, I am still experiencing the same problem that the recall was for. Since then, the issue has returned, and I am concerned that the original remedy did not resolve the safety concern. Can you please advise me on the next steps to have this issue re-inspected and corrected? Thank you for your time and assistance. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car keeps giving a “Shift To Park” message when vehicle is already in park. Leaving the vehicle running and draining the battery, let me stranded a few times because it was dead. Tried almost everything to get it to go away but it keeps giving the same message everytime I go to park it and vehicle won’t shut off. Very inconvenient and unsafe, Doesn’t seem to be a recall or fix for this issue.

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!
Feb 20, 2023
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
Dec 24, 2022
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.
Dec 17, 2022
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.

On Nov. 18th 2022 while driving on county Rd at 55mph I slowed to make a left turn. As I went to accelerate at about 30mph the vehicle lost power, I pulled over shut off the vehicle. I started the vehicle and the engine symbol appeared, I continued to drive, I had power so I entered the interstate. About 2 min. of driving The vehicle went from 70mph to 40mph. I pulled into a dealership to see if I could get the vehicle looked at. They said they were booked up that it would be about ten days. I continued to my destination there were no other issues beside the engine light staying on. At a half tank of gas I filled up, when I went to leave the The engine light was off. No other issues since.

I paid a significant amount to have my car fixed after bringing it initially the first time in May. Since then I have had to return my car multiple times every other month because the engine light continues to come on and they don’t know why. I have worked directly with JR and have gotten no result. The engine light continues to come on and they continue to not be able to know why, they keep my car for multiple days and can’t explain why the light is on or what they did to remove it and then it comes on a few days or months later with the same issue that they cannot explain. I bought my car in over five times already I have contacted corporate to no avail. When I brought it back the second time they claimed a bunch of things were wrong with it that weren’t wrong the first time, every time there is a new issue but they can’t describe what is the cause of the issue or can they give me an explanation on what keeps happening the last time they claim it was an electrical malfunction but could not explain any details and waited until they were closing to contact me. My engine light has since come back on which means I would have to bring it in again. I contacted corporate they were supposed to call me back, never heard from anyone. I’ve been working directly with JR who I constantly contact and he does not follow up at all or call me back like he says he would and the issue continues to happen and he is very aware of it for my initial review. They have to leave my car there for multiple days to not get updates to not get any information, they don’t look at it they don’t even know what’s going on with it, it doesn’t even make any sense at all now I’m driving a car that could potentially be unsafe and I’m bringing it to the only dealership that is closest to me Chevrolet and they can’t even help. My car is a 2018 Chevy Malibu that I take extremely good care of yet no one knows why the engine light keeps coming on.

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
Dec 13, 2022
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.

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.

My ‘18 Malibu LT has over 39K miles , and just tonight, i started my car , the engine light and traction control light both came on, followed by a message saying “Engine Power Reduced”. I then decided to drive for a little to see if i notice any problem. After driving for about 4 minutes , my car went from 37mph down to 20mph . It felt like the engine was forcing itself . So i then pulled over to the side of the curb, turn the car off, then back on. i noticed the warning engine light was still there but the traction light weren’t there no more. So i drove back to my place , turned my engine off. Then i plugged my diagnostic device to see what code(s)were they, and 1 code came up and it was P2138. Which is Throttle/Pedal Position Sensor. Oh by the way, I also would like to mention one more thing which is the “Shift to Park” message i started seeing whenever i park my car (putting the gear in park) and this first happened when my car was at 38K Miles (about a month ago).

The pedal assembly is malfunctioning, causing the vehicle to throw an error and suddenly reduce the speed of the vehicle dramatically, often to dangerous levels, i.e. reducing the vehicle speed to below 30MPH suddenly on a highway. The vehicle will randomly experience the malfunction in the pedal assembly with no apparent pattern or reasoning. The issue is remedied by turning the vehicle on and off again. Additionally, the code clears most often within 24 hours.

SERVICE BRAKES

The brake booster unit, vacuum pump , brake light switch failed and malfunctioned and it is available. My safety and others on the road was at risk due to brakes being stiff and hard as a brick. Possibly nearly hit an other vehicles on the road. No warning lamps or other symptoms prior to the failure.

The vacuum pump for the brake assist is made from bad metal which can break and screw up the camshaft, chevy knows of this problem they have a recall for the 2017 model but not the 2018 which they both have the same exact problem, they need to take care of this it is a major safety issue, I have no brakes and it could potentially ruin my engine.

Vacuum pump stopped working and shattered into my engine. Breaks suddenly stopped working while driving.

Apr 23, 2025
I am filing a complaint regarding a brake vacuum pump failure in my 2018 Chevrolet Malibu. The failure of the vacuum pump led to a complete loss of brake assist, making the brake pedal significantly harder to press. This issue directly resulted in a complete loss of braking ability, which posed a serious safety risk while driving. The vacuum pump in these models is camshaft driven, and its failure caused damage to the camshaft. This issue is documented under GM Technical Service Bulletin PIP5835 and is known to affect certain 2016-2022 Chevrolet Malibu models equipped with the 1.5L LFV engine. The brake failure due to this issue could have led to a life-threatening accident, and I am deeply concerned that other drivers may experience this same risk. Despite reaching out to GM and the dealership, goodwill assistance was denied for this known defect. I believe this is a major safety hazard that needs to be addressed immediately. Vehicle Mileage ~120,000 Repair Estimate: $2106 for camshaft, vacuum pump, and related components Incident: The brakes became unsafe leading to a dangerous life threatening driving situation

Purchased a car for financing from Barret Motors and 2300 Lakeview PKWY, Rowlett, TX and as soon as I drove it off the lot on [XXX] the engine light popped on. I immediately called and was told to just take it to Chevy/GMC for servicing but was not told why, but just because the engine light was on I was told to go. I couldn’t take an appointment asap because I just started a new job which they also knew. The car has had a recall since 09-06-19 for an engine control module. Which is a serious issue and this car never had it completed and sold me a car with possible engine issue and did not inform there’s a recall on the vehicle for almost 5 years now. I took the car to get serviced at Chevy for the recall on 09/09/2025 and now I am facing multiple issues with the car from it not being done years ago. The recall was N192221960 and it’s major so to sell a car before getting the properly service and I have been financing the vehicle for a year now. Never not once late and I am now being told there’s nothing can be done. I have photos of the car having the engine light pop on the same day u financed this vehicle. Barret knew a serious engine problem was effecting this car for 5 years and still deciding to sell it to me for financing on [XXX]. I need immediate assistance.

Vehicle component has not been inspected by dealer or anyone else. The check engine light and logo came on as the engine was shutting down. I went into the trunk on the passenger side and shook and twisted the wires going into the control module mounted to the trunk wall. This was suggested for the 2016 Malibu which had a recall. There should be a recall on the 2018 also. After repeated shaking and attempting to start the motor, it finally started. I drove it home and parked it. When I went to read the code, the engine started and ran for a couple of minutes and stalled again. The code was P2BB3.

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.

I was going about 75 mph on the express way with one lane open due to construction. My car started losing power.I heard the chime and upon the dashboard were the words power reduced. My car slowed down in a matter of seconds to around 45 mph. A 18 wheeler was trailing behind me. I quickly jumped in the emergency lane to my right and took the next exit while riding the emergency lane. I shut the car off at the gas station, sat there for about 10 minutes, restarting my car helped temporarily. I was 3 hours away from home and had to drive back unknowingly if I will make it or not. I reached out to Chevrolet and was told to bring it in and leave it but they had no loaner cars for anyone at that time. I have replaced 2 sensors and now my start /stop has quit working. I spoke with 5 visitors at Chevrolet and we all were having the same issues. This is something ongoing according to my research on this particular vehicle and should be recalled asap.

Car hesitant to crank, once the Start/ stop button is pushed, the car will start, run smooth for a second or two then start to shake and putter like it’s not getting fuel and loses it power and cuts off. I have to go through this process 5/6 times before the car will stay crunk. While driving Car will out the blue say reduced engine power and acts as if it does not want to pull or it is losing power! The car also has the eco saving feature where it cuts off at every stop and there is not an option be turned off and car is hesitant to start back up after it cuts off. Car is now starting to smoke from the tailpipe. The VVT intake and exhaust solienoids have oil getting into them and the PCV valve is about to crack open. The car throws codes like rich fuel intake, something to do with the catalytic system (in which I’ve put a brand new catalytic converter on the car and it did not solve the issue) it also throws codes about a throttle and cam sensors and a few more codes.. I see where there are recalls for the (same make, model,year, and engine size) but my cars VIN is not included with the recall! Can we please get this as I need my car and need this issue fixed as soon as possible as it is dangerous for me and my 2 year to travel in this vehicle.

My turbo failed while I was on a very busy highway, causing me from going 70mph to 35mph in a matter of seconds and almost being hit. This put my life and my friends life at risk since we were in the left lane. Now that I’ve been fighting with the dealership ti help make this right they found a GM warranty that fixed and updated electrical sensors. We fixed that first because at the time we thought that was what it was. My turbo gave out again up in the mountains almost killing me and my friend a second time on a busy road. We made it to a parking lot and called a tow truck. Now the stabiltrak is showing up and the car refuses to start, it makes a whooshing sound and doesn’t start completely. (There is fuel, oil, etc). I was sold an unsafe vehicle and now I’m stuck paying 500$ a month for a car that’s unsafe and refuses to work even when it’s been fixed. The dealership is refusing to help me, I’m at a loss. I still owe 18k and I can’t have an in working car sitting in my apartment complex, it will get towed and cost me more money.. I need help. I was sold a car that almost killed me twice and no one seems to care.

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.

Saturday morning this is now the 3rd time it's been fixed and safe to drive. Once by the dealership in Baltimore Towson area. 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. This needs addressed it happens after the batt needs changed I know 4 other owners 1 had just got one that's what triggered his same codes problems. Im I've Googled it but not one person solves it.

Purchase car in December 2018, had 3 engine replacement. I am currently in the 3 engine replacement. And still experiencing the same issue - check engine light permanently on for 2 months now. Issues A whistling sound from an opening vent in the hood since last engine replaced. Call stalls, reduces speed and jerk when trying to accelerate . Have reached out to Reed lallier Chevrolet they making it seems that normal and ok. I am scared to drive and cause an accident because the car stalls before picking up. When you put the car in park, the car still not registering at park it is still moving you have to sit and clear the dash board (shift to park, even thou it is in park). Chevrolet only gave 1 engine replacement and $100 gift card. Every other expense is on me, when I still have to pay for the lemon. Unable to locate most recent engine replacement sheet. But can retrieve from dealership if needed. This car is full service and maintained in the allocated time frame reed lallier has the file of needs be.

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

Engine reduced while driving
Oct 31, 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.

When putting my vehicle in park to turn off the car, a warning light comes on to put vehicle into park. The vehicle is already in park and am unable to turn off the vehicle. In order to turn off the engine I must repeatedly turn it on and off and hit the gear shifter multiple times. This problem is becoming more and more frequent. I see numerous other 2018 Malibus in the complaint section reporting the same issue. Come on Chevrolet fix this problem!

Transmission Surge Accumulator System Performance. The car fails to accelerate once it comes to a complete stop, traffic lights, etc. The car will rev up to 5000 RPMs but will not reach 10 mph. This causes problems when driving and I was almost hit on several occasions (more than 8 times) on my drive home to be safe again. The car was taken to the dealership and was reported to have been fixed, after paying a $100 deductible, but only ran properly for one day. Again, I was almost hit 5 times while driving back home, after the repair was made. The check engine light came on after the car presented issues, as I was out running errands, the car was losing power and was not performing well. About 20 minutes after the initial issue, the check engine light came on. I took the car to Auto Zone where they were able to run the diagnostic that came back with the code, P171D Transmission Surge Accumulator System Performance. This took place twice in one week, with the dealership fixing the issue on Tuesday and it failing again on Saturday (after the car sat idle for 3 days, while I was on vacation).

There was an issue with the Engine and Transmission System. My Engine light came on and I received a warning that the Engine Power is Reduced and I had to pull over because the speed of the car reduced to 20 miles an hour. This happened a month again and then the car would not start. We bought a new battery and everything was fine until today were it happened again. I have to travel on the highway a lot and cannot have that happen again or I can be in trouble by causing an accident.

Driving normal. Upon application of brakes, brake pedal became stiff and brakes did not function normal. Had to apply immense pressure to stop and it sounded like brakes kept locking up. Vacuum pump that supplies vacuum for engine with turbo to function, along with the brake booster to be able to apply normal braking power, was destroyed. The inside of the vacuum pump is in pieces and part of the bushing that connects into the engine was broken. Caused by faulty vacuum pump, or faulty cam shaft. If this had happened while in traffic, it is likely a crash would have happened. Damage caused to the vacuum pump resulted in metal pieces in the engine block as well.

I was driving the vehicle on a busy road and a message came up on the display above the steering column saying Engine Power Reduced. I went to brake and was unable to push the pedal in as it was extremely stiff. There were vehicles around me and I tried to use both feet and stand on the brakes and was able to get a little bit of movement but the car still didn't slow down. I had my significant other and brother-in-law in the car and we were all horrified we were going to get into an accident. I turned the hazard lights on and was able to steer to avoid hitting several vehicles and when traffic finally cleared I was able to get over and off the road into a gas station that was uphill and allowed us to slow down and finally stop because I put the vehicle in neutral tried the parking brake which got us to a complete stop and shut the vehicle off. There had been no previous issues with the brakes or messages such as the one that came up right before this issue occurred. The vehicle had to be towed and the repair shop told me the cam driven vacuum pump failed which caused the brake booster to not function. When this failure occurred, it damaged the intake and exhaust camshafts, crankshaft, and several other components. The cooling system and oil to be flushed out as I was told there was metal debris from the damaged parts caused by the vacuum pump failure in the fluids which had been all completely flushed and changed including cooling system, transmission fluid, and oil change The total cost of repairs as a result of the vacuum pump failure setting off a Domino effect of damage was $3536.40.

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.

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.

While driving on the highway my dashboard displayed a warning of “reduced power steering “, engine light came off and on, loss of speed , and “stabilitracking” light came on. Brakes also vibrated badly as if they were unable to hold a grip. I was unable to accelerate and was really in danger. The car was taken immediately to the dealership where they replaced the battery and told me it was repaired. On my return from the airport the next morning at 4:30 the same lights and warnings displayed on the dash once again and I had it towed immediately to the dealership. We are now 3 days in and I have gotten no explanation as to what is going on with my vehicle.

Cam-driven Brake Booster Vacuum failure without warning. My engine died, my brake pedal and steering wheel stiffened, while in moderate traffic. I had use excessive brake force to slow my vehicle to a stop. Currently have 78,012 miles as it is sitting in the repairs shop. This is the first time it has happened, but I worry it may happen again because upon further research, it is a very common part failure.

SHIFT TO PARK
Oct 07, 2025
I am writing to formally report a serious safety concern with my 2018 Chevy Malibu related to the brake booster vacuum pump. My vehicle has exhibited dangerous symptoms, including a hard brake pedal and reduced braking power, which I’ve now learned may be connected to a known defect affecting 2013–2022 Malibu models. These issues have significantly compromised my safety and that of others on the road. I’ve had to deal with sudden braking difficulties, and the repairs have caused financial stress I was not prepared for. I am now aware of the pending class action lawsuit (Johnson v. General Motors LLC) that details this same problem.

REDUCED POWER TO ENGINE . Previously had recall for this issue, which was replaced by Chevy service center. About a year later I had the same problem but had to pay out of pocket because there were no active recalls on the issue. As of today, I am receiving the same “REDUCED POWER TO ENGINE” error and check engine light keeps coming on. This happens randomly but frequently almost every single day. Error will shut off after restarting car and then happens again not long after. I’ve had this issue with multiple Chevy Malibus that I have owed and there is currently a class action lawsuit against GM for this exact issue.

I keep hearing a clunking noise in the rear of my car and it gets louder at low speeds and when I turn when stopped. I have been doing research to try to see what it could be and I am seeing that this is a common issue with this car and there's no recall. The parts alone are $200+ and then you have to pay for labor. This is ridiculous for a faulty assembly problem due to GM.

While driving high speed such as are on the highway vehicle jerks and has gotten worse now so aggressively it almost jerks from my grip to the left. It’s without notice and over correcting at those speed could cause my vehicle to roll, or jerking into on coming traffic or into another vehicle to the left of me and the direction each time it’s occurred it’s jerked to the left. I’ve previously blamed it on the road or the wind when it’s happened since I’ve had it now almost 5 years. Now it’s getting so bad I’m afraid of my safety and others in my vehicle or other drivers I might be thrown into when it jerks violently and without warning. This is my only form of transportation and I owe money left in the vehicle and feel I’m being put in harms ways as well as other that could be impacted in my vehicle or other drivers.

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.

While driving 70 mph, I get an Alert that stated reducing speed. And my check engine light came on. This is not the first time. Lucky I was able to get off the Highway without getting into an accident. Also my car sometimes will not cut off because it says my car is in shift even though I have it in park. This is dangerous to have a car reduce speed while driving 70 mph to Abruptly go 40 mph. Last time this happen a month ago no codes came up and the check engine light eventually went off. But now my check engine light is back on again.

I repeatedly get a “reduced power to engine” alert on my dash which causes my car to decelerate and I lose my power steering. This last time, the alert popped up on my dash, my car decelerated, and then my brakes would not work. I could not push the brake down to stop my car and ended up in a ditch. My brakes are now hard and I cannot start my car because of it. I have already had the recall for this issue fixed in the past but this will be the 3rd time I have brought my vehicle in for the same problem. I had diagnostic codes ran on my car soon after the accident happened and have attached the pictures to this form.

12/27/2021 I started my car to leave work & noticed a loud tap. I've worked for dealerships in the past & was part owner of my own repair shop for many years. Popped the hood, checked the oil level which was good, & figured I'd be fine to drive it home to park it & then hook the scanner up. Mid-way home I received an engine performance notification on my dash, but other than that it seemed safe with no diminished speed. Less than 3 miles from home I went to stop at a red light & had the hardest brake pedal I've ever felt in my life. I was fortunate nobody was around me so I put all the weight of my body on the pedal to stop the car at the light. The engine was sputtering & the steering felt tight & it felt like it was stalling, with a green turn arrow I risked crossing the highway & was able to safely park in the community's rec center. I'm not one who is quick to take anything to the dealership because many times the techs are lazy, so I hit the web & found two things. One - there is an extended warranty on the TPS sensor which is the entire gas pedal itself. This could explain the engine performance notification, but not the lack of brakes. Upon hours & hours of additional reading I found the problem - the vacuum brake pump. We ordered it & replaced it but I can tell you my engine likely needs an additional camshaft replacement for it to ever be right again. Two codes remain: P0014 & P0017 - Exhaust camshaft/crankshaft position not plausible. What was the condition of the vacuum pump? It was SHATTERED & had spewed chunks of metal directly into my engine. I was lucky that day, had I gotten 1/4 mile down the road I could have wound up in a lake instead of a parking lot. GM should be ASHAMED of this design & it's continued failure to not only address the issue, but lie about it in the process. First owner, failure occurred at 54,500 miles - no warranty. What scares me the most, is how many times the same owner has had this pump fail again & again.

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.

As I was driving down the highway at 60 mph the road was clear at the time of any debris my car suddenly had two lights on the dashboard. On the left was the traction control light and the right side was the engine light. On my computer display was the words “reduced engine speed”. My car suddenly slowed from 60 to about 30 mph in a matter of seconds. It was like I had slammed my brakes. This all happened simultaneously I attempted to pull over safety and turn the car off and restart it. The lights remained on. My car was not able to get over 27 mph There was no warning what so ever If anyone would have been behind me I would have been rear ended At this time I took it to a mechanic who put it on the computer it was coded at the pedal position sensor. He was able to save the code, clear it so I was able to drive the car and advised to drive it locally for a while in case it would do it again as it is unsafe. The closest Chevy dealer is over an hour away from my town and at the time of day it was not safe to drive the car to the dealership for confirmation.

I STARTED THE CAR AND REVERSED OUT OF A PARKING SPACE. AFTER SHUTTING THE CAR IN DRIVE, I PRESSED THE GAS AND THE CAR BARELY MOVED. I PULLED OFF TO THE EDGE OF THE PARKING LOT AND PUT THE CAR IN PARK, TURNED IT OFF, WAITED A MINUTE OR 2, AND RESTARTED THE ENGINE. I PUT THE CAR IN DRIVE AND IT WENT FORWARD. I HAD TO STOP AND SLIGHTLY REVERSE BECAUSE A CAR WAS COMING TOWARD ME ON THE STREET I WAS TURNING ONTO. I PUT IT BACK IN DRIVE AND TRIED TO TURN OUT OF THE PARKING LOT. AGAIN THE ENGINE WAS RUNNING BUT THE CAR BARELY COASTED. IT ACTED LIKE IT WAS NOT CHANGING GEARS. I PULLED ACROSS THE STREET BECAUSE A CAR WAS COMING INTO ANOTHER PARKING LOT. WE WERE ALMOST HIT BECAUSE THE CAR WOULD NOT GO. I PARKED THE CAR TURNED IT OFF. WAITED A FEW MINUTES AND RESTARTED IT. I GOT OUT AND THE ENGINE SOUNDED SLIGHTLY OFF ... IT WAS CLICKING ALMOST LIKE THERE WAS A TIMING ISSUE. I GOT BACK IN THE CAR REVERSED OUT OF THE PARKING SPOT AND WENT FORWARD. THE CAR STARTED FORWARD AND I TURNED BACK ON TO THE ROAD. SUDDENLY THE RPM SHOT UP TO OVER 400 AND THE CAR LURCHED FORWARD WITHOUT APPLYING ADDITIONAL GAS. I APPLIED THE BRAKES AND KEPT DRIVING. THE RPM RAN HIGHER THAN NORMAL ON THE WAY BACK TO KOKOMO. IT WAS NOT DRIVING CORRECTLY AND STILL ACTED LIKE IT WAS NOT SHIFTING GEARS CORRECTLY. I DROVE IT TO THE NEAREST DEALERSHIP IN KOKOMO, IN. ERIK'S CHEVROLET AND THEY COULD NOT FIND ANY ISSUES. WHEN PRESSED THEY TRIED TO SAY IT WAS OVERDUE FOR AN OIL CHANGE WHICH IS NOT TRUE. THE INDICATOR JUST CAME ON RIGHT BEFORE THIS HAPPENED. IT HAS ~7200 MILES BUT IT HAS FULLY SYNTHETIC OIL. THEN THEY TRIED TO SAY IT WAS LOW ON OIL AND THE OIL LIFE WAS ZERO AND THAT CAUSED THE ISSUE. AGAIN NOT TRUE BECAUSE IT WAS AT 4% AND I CHECKED IT PERIODICALLY AS STATED IN THE MANUAL. THERE IS A RECALL RELATED TO AN ECM MALFUNCTION. I AM CONCERNED THIS IS RELATED AND THE FIX MAY NOT COMPLETE.

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).

Every so often I get an indication of engine power reduced, but every time I go in to get it checked it's off. I have recently just learned through research online that the issue is caused by a certain condition that gives false reading to the electronics. I have contacted GM and GM financial about the recalls on my cars of the same year. I have not been in a wreck but I have had the issue of engine reduced power in the middle of traffic. Cox Chevrolet in Bradenton has turn me away about the issue GM financial is giving me the runaround neither one mention anything about a recall instead I get a estimate $400 /$808.50/1900.41 all to fix ECM as I told the mechanic I was driving with no problem through the day me and the kids at the park when it was time to leave the car sounded like it just didn't have no gas. We was stuck tell 10:45 we waited two hours for the tow truck. I have OnStar and get monthly reports on my car. When the check engine light comes on OnStar has no indication that's why I believe it is the same ECM. I was told by Chevrolet Maher service manager of St Pete to get my car off their lot as I said before I got a estimate of 400 that went up to 800 and all I did was ask why

AT THIS TIME MY CAR STARTED TO DOWN SHIFT AND THE MORE I STEPPED ON THE ACCELLERATOR NOTHING HAPPENED. MY CAR THEN TURNED OFF ON THE HIGHWAY. I IMMEDIATELY SHIFTED TO PARK AND STARTED THE VEHICLE AGAIN BECAUSE I WAS IN FEAR OF GETTING REAR ENDED. WE HAVE TAKEN THE CAR TO THE DEALERSHIP 4 TIMES FOR THEM TO FIX IT AND THE LAST TIME, THEY SAID THERE WAS NOTHING WRONG WITH IT. WE STILL HAVE EXCELERATION ISSUES WITH THIS VEHICLE. WE GOT A RECALL NOTICE OF SOFTWARE FROM CHEVROLET BUT THE DEALER SHIP IS UNAWARE OF THE REPAIR AND I DO NOT BELIEVE THEY CAN CORRECT THIS PROBLEM.

I have a 2018 Chevrolet Malibu . Lately after I park my car it’s comes up on my screen to Shift to Park. But the problem is that my vehicle is already in park mode. What I’m trying to find out if there have been any other complaints or concern regarding this issue. I’m 83 years old and I drive my vehicle minimally. It’s only has 9100 in mileage and I’ve taken it to my dealership in Parkville, Md 21234(Jerry’s Chevrolet)since my purchase date in March of 2018. I’ve done every service requested by schedule. I need to know if I take this in is this covered issue under my power train warranty since this controls my car movement. It’s very disturbing to me that it would not be, again I’m a senior citizen on a fixed income and every penny count these days. I look forward to hearing from someone please. My vehicles as in park

After diagnostic troubleshooting from DTCs on a check engine light, it was discovered that the brake vacuum pump connected to the engine was completely nonfunctional. Previous symptoms included stiff brake, loss of brake power at random brake periods which could have cause and accident with other drivers, and finally malfunctioning sensors attributed to the exhaust system. This also led the vehicle to be unable to pass state regulated Emissions testing because of the inability to maintain proper emissions levels. Brake Vacuum pump that was removed from vehicle to inspect and diagnose is still available for inspection. Recent findings show that Chevrolet/GM is aware of the issue in their vehicles but refuses to address or replace faulty brake vacuum pumps. It is a common problem amongst 2013-2022 Chevrolet Malibus. Vehicle that is in question was inspected by a certified mechanic shop with failed emissions test. Solid check engine light appeared once the brake had become harder to push and stop the car. OBD scans show DTC codes that were pertaining to MAF and MAP malfunctions in readouts and communications to the ECM. After further inspection, the ABS module had been acting as "backup" for hydrolic brakes system that had zero vacuum to power the brake booster, this could have caused the engine to stall, longer than normal stopping distances (stronger risk of rear ending other drivers), and multiple components and sensors to fail, requiring them to also be replaced.

The rear knuckles on these cars are constantly going bad and the parts are expensive and so is the labor. So we have to pay a fortune to fix a common issue that GM should be recalling and fixing for the people who buy these vehicles. It's crazy how common this issue is and it's still not recalled. If you hear a clunking/rattling noise coming from the back of your car then it's almost certainly a knuckle problem.

Steering asst warning came on. This happened in 2022 when I got the vehicle and it’s now happening again. When stopped with foot on brake and auto stop engaged , you take foot off brake steering wheel jerks and steering asst warning comes on. There is also a problem with shift to park. Vehicle shifted into park vehicle doesn’t recognize that it in park and vehicle can’t be shut off until it recognizes that it’s actually in park. Chevy knows this is an issue and will cover it under bumper to bumper warranty but will not fix it under a recall or outside of bumper to bumper warranty. Vehicle has a p1101 code that comes and goes. Engine filter has been replaced, throttle body has been cleaned, MAF sensor has been replaced, and the issue continues to persist. There is no know way to fix this. Rear seat belt doesn’t work. Vehicle came like that. Vehicle has had multiple issues. Contacted Chevy they want me to pay for a diagnostic out of pocket and submit to them and possibly they will then help. These are all known issues that they are not addressing.

I was informed the vacuum pump went bad and rendered the vehicle inoperable. The vehicle would lose acceleration, shut off during auto stop and caused me to block traffic. The brakes also locked up, which almost caused me to crash in a residential neighborhood. I tried to see if there was a recall on this but I was told the recalls were handled in January of 2020 but I started driving the vehicle between July and August of 2020. This incident I'm reporting just happend 3 weeks ago. I realized there are many other issues regarding this matter and need this addressed because this almost caused bodily harm. The dealership wants me to pay for repairs on a vehicle that seem to have defective parts that jeopardise customer safety and is not being rectified.

The contact owns a 2018 Chevrolet Malibu. The contact stated that while on a trip and traveling at high altitudes, the check engine warning light was displayed on the instrument panel. The contact used a code reader which showed that the barometric pressure sensor was defective. Once the contact returned home, the mass air flow sensor was replaced. The following year while traveling in the same region at high altitude levels, the failure recurred. The contact also stated that the engine booster had started to fail due to ice accumulation in the charge air cooler (CAC), which restricted airflow. As a result of the failure, the vehicle failed to accelerate above 25 MPH. Upon investigation, the contact discovered Technical Service Bulletin No: 18-NA-069; which the contact linked to the failure. The dealer was notified of the failure, but the contact was informed that the vehicle was out of warranty. The manufacturer was also notified of the failure and referred the contact back to the dealer for assistance. The vehicle was not repaired. The failure mileage was approximately 76,000.

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.

She believes the car's Lane Keep or Lane Departure systems are the cause of the accident. She has asked me to assist with reporting the accident and wants an investigation done. She received an "Lane Departure" warning about 3 days prior to the accident and again on the morning of the accident when she started the vehicle. She is unsure what the exact message said. When the accident occurred, she states she was vigilant, alert, and focused on driving. She was not on the phone and did not have any other distractions in the car at the time. She was driving on the Hwy when all of a sudden the car jerked her violently out of the lane and into a bridge. The car bounced off the bridge and ended up a ways down the road on the other side. She has a concussion, fractured sternum, fractured sinuses, cuts, bruises, and other injuries. Q. What component or system failed or malfunctioned, and is it available for inspection upon request? A. Yes, the vehicle is at the junk yard Q. How was your safety or the safety of others put at risk? A. Severe bodily damage Q.

My brake vacuum pump seized while driving in the far left lane on the freeway. My car began to lose power and my rpms dropped and rose back up quickly making my car lunge forward and back quickly multiple times. My check engine light came on and a warning saying my engine was losing power flashed across the dash.I exited the freeway and pulled over to a safe location, when attempting to stop my car I noticed that the breakes were stiff and would not move and I had to push the emergency break to stop the car completely. I had my car full of family members and all of us were extremely sacred and worried for our safety and those of others around us as the speed was no longer under my control.

I have a 2018 Malibu with a very long list of major issues. The Engine loses power constantly along with a “Engine Reduced Power” warning and check engine light. I get a constant “shift to park” message even after placed in park. All the steering wheel buttons/controls do not work. With the exception of the cruise control. Car almost red lines after the power message displays when you try to increase the speed of the vehicle. The back axle/suspension/hubs make a very loud popping sound when I back up or drive forward. Both back wheel assemblies make a very loud wobble noise when driving. Almost like the assemble is going bad. The Auto Stop/Start causes a lot of issues. It causes the car to jerk horribly and that’s when you hear the popping in the back axles the most. Idk if there is an option to turn this off in this model. But, if there is I can’t access the message center because the steering wheel controls/buttons don’t work. Also upon restart the car runs extremely rough and tries to die. The car has really bad powertrain issues. The car not only loses almost all power….. but, also acts like the transmission is slipping when taking off from a dead stop. Causing it to jerk really bad when the transmission actually catches. The brake system also seems like it has a lot of issues. Here recently the brakes seem like they don’t want to stop the car and that leads to pressing the brake pedal down harder resulting in the brake finally stopping the car in almost a dead stop. This could cause a rear end collision or a collision after your designated stopping point. Every time it rains my trunk gets soaked with water leading to a horrible mildew smell and damaged property in the trunk. Also, the steering wheel will start wobbling uncontrollably when driving down the road and then just stops. It causes a violent shake in the front end until it stops. I’m sure I missed a few things just because of how long the list is. I’m hoping for a solution to these problems.

The rear liner had water indications, with an odor of mildew in the car. I couldn't drive around with mildew in my car. I notuved shortly after i purchased yhe vehicle that the brake light was cracked. I didmt think much of it, thought it was just a cosmetic thing. It was taken to my dealership and they confirmed the water was getting in through the cracked brake light. I did a little research and it seems to be a common issue with Malibu's. No warning other than the smell, that made me check the back seat.

My car constantly gives an error saying the power is being reduced to the engine. It was repair 3 months after I bought it but it didn't fix the issue. These cars a danger to everyone around us. They reduce speeds to very low numbers even on the freeway, when yielding to turn left the car won't go but will drift into oncoming traffic, and many times the car won't shut off. It says it's not in park but it is. The seatbelts look like they're secured but with one good tug they'll come apart. And I slide when braking even without snow or rain.

The vacuum pump on my vehicle has gone out for the 3rd time in 2.5 years. This creates a safety issue as that the brakes stop working and it takes an extreme amount of pressure for the car to stop. This has occurred once on the freeway and twice in heavy traffic areas. This could cause an accident and potentially seriously hurt or kill someone. This has occurred once before the engine was replaced and twice since it's been replaced.

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.

“Engine power reduced” shows on dash after I’ve taken it to the dealership. I’ve been on the highway where the speed slow down drastically cars coming behind me! Very dangerous! Also “shift to park” displays when it is already in park! Have to either wiggle the gear shift or, turn car off/on several times for the message to go away. Also when backing up, there’s a popping noise in the rear. Dealership acknowledged I want the only customer with this issue. Claimed they didn’t find anything wrong. I purchased this vehicle in 2019 and it was only a year old. Issues started almost simultaneously at the end of 2019…Too new for all of these issues.

Recently my car had been shutting off at stops. I know chevys shut down when at stops but now it shuts down my radio lights go off locks on doors unlock then lock. then when it turns back on it says driving assist is reduced drive with caution. Then another alert pops up saying doors are unlocked. Now when I’m driving sometimes it slows down on its own and won’t let me go faster. It’s very scary when on freeway cause I’m worried it’s not going to speed back up and I’m going to get rear ended. Another alert With the first letter S comes on but it turns off so fast I can’t see what the word is. It been stalling when I’m at a stop. It does turn back on after a few seconds. The engine light comes on periodically and eventually turns off. Also when I go from drive to reverse it does not change gear smoothly sometimes it will jerk the entire car and make a loud noise as I’m putting into reverse. There has been two times my radio screen has gone completely black and won’t turn on for several hours. I use my car everyday to commute to and from work. I have two jobs so I do spend a lot of time driving and this is scary not knowing if my car is truly safe to be on the road. I trust the Chevy name that’s why I chose it but now I’m not so sure it is safe.

When car restarts after being in Auto stop start mode the steering wheel jerks uncontrollably. The car obviously has a suspension problem. Dealership failed to repair issue properly after several attempts. Also appears dealer made false diagnosis to prevent repairs under bumper to bumper warranty. GM Dealer also refused to repair issue under Power train warranty. Another dealer wanted $555 just to check issue. A couple of weeks ago I suddenly lost control of the vehicle. I was at a red light. Car went into auto stop start mode. When light changed and car restarted, as I proceeded to take off the steering wheel jerked away from my hands, and I lost control of the wheel and car. Luckily it was a single turning lane and no other vehicle was next to me turning. I pulled off side of the road in shock. I drove about half mile and warning light displayed on dash. Warning Message States STEERING ASSIST REDUCED DRIVE WITH CARE" what was a brand new 2018 Chevrolet Malibu purchased in 2019 is now unsafe and inoperable. This steering component issue along with several others were brought to dealerships attention and were not acknowledged and were dismissed. After several other failed attempts this dealership purposely ignored this issue months ago while car was still under bumper to bumper warranty. Dealership also refused to repair this issue under powertrain warranty. 2018 Chevy Malibu has had 5 recalls to my knowledge. This has been spontaneously producing white smoke from underneath the hood on several occasions. I have video and witnesses. This car was sold as a brand new car. This car had recalls at the time of purchase and never disclosed the recall information. Also be advised that I cranked the car today just to keep the battery in tack because car has been sitting since June 10. The car choked, head lights went flickering, car could barely stay on. it appears to be an engine issue. These cars should not be on the road. They are not safe.

I WAS RECENTLY GETTING ON THE HIGHWAY IN MY 2018 MALIBU AND HAD ABSOLUTELY NOOOO ENGINE POWER FOR ACCELERATION! LUCKILY I WAS ABLE TO GET ONTO THE MEDIAN BEFORE I WAS REAR ENDED BY THE FAST MOVING CARS! SIMULTANEOUSLY THE 'ENGINE POWER REDUCED', 'SERVICE TRACTION CONTROL', AND 'THE 'TRANSMISSION' SERVICE LIGHTS CAME ON! THEN AS I WAS GETTING OFF THE HIGHWAY AT THE NEXT EXIT, I WENT TO STOP AT THE LIGHT AND I HAD NOOOO BRAKES! LUCKILY I PUSHED AS HARD AS POSSIBLE AND GOT MY CAR TO STOP WITHOUT A SECOND TO SPARE! I HAVE NO DOUBT THAT 99% OF DRIVERS WOULD HAVE EITHER BEEN SERIOUSLY INJURED, OR SERIOUSLY INJURED SOMEONE ELSE IN THE PROCESS OF CRASHING THEIR CAR! I HAVE A PRETTY GOOD KNOWLEDGE OF CARS , FROM RACING MULTIPLE C5 AND C6 CORVETTES, BUT THIS PROBLEM HAD ME STUMPED FOR A WHILE. I TOOK THE MALIBU TO MULTIPLE GM SERVICE DEPARTMENTS, AND NONE OF THE MECHANICS COULD COME UP WITH A REASON WHY ALL THOSE SYSTEMS FAILED SIMULTANEOUSLY, AND MULTIPLE MECHANICS ALL SAID IT WAS EITHER THE BRAKE BOOSTER OR THE MASTER CYLINDER. I JUST DIDN'T SEE EITHER OF THOSE PARTS BEING THE REASON FOR THAT MUCH OF AN EFFECT ON THE CAR, AND LUCKILY I REMEMBERED THAT GM TRUCKS WERE HAVING A MAJOR ISSUE LOSING BRAKES DUE TO THE VACUUM PUMP. SO AFTER AN INSPECTION I FELT PRETTY CONFIDENT THAT WAS MY BRAND NEW MALIBU'S PROBLEM, SO I WENT TO THE PARTS COUNTER AND DROPPED $330 ON MY WARRANTIED MALIBU, AND SURE ENOUGH THE CAR WAS FINE AFTER THAT! HOWEVER, A MAJOR CONCERN OF MINE IS THAT THE OE VACUUM PUMP WAS MISSING CHUNKS OF METAL, AND CLEARLY THOSE CHUNKS OF METAL ARE FLOATING AROUND IN MY ENGINE! SO DESPITE MY REGULAR MAINTENANCE, AND EVEN EXTRA MAINTENANCE, MY CONFIDENCE IS NOT VERY HIGH, AND I'M CONSTANTLY WAITING FOR THE CAR TO HAVE ANOTHER PROBLEM WITH THE NEW VACUUM PUMP, ENGINE OR BRAKES!
