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!

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.

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.

The steering wheel is jerking when in the position to turn, and waiting at a light. The STOP ENGINE Feature seems to make the jerk motion and also sends an ALERT MESSAGE which is a quick flash STATING "Steering Assist is REDUCED- Drive with Care". According to a SERVICE BULLETIN Provided by GM BULLETIN #19-NA-182 AUGUST 2019. This is a problem that needs to be corrected, for the safety of my family and others in the vehicle and on the road. Next, the car shut off and the command center went blank,

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.

MOTOR DIED GOING DOWN THE ROAD Car is available for inspection If I had been crossing the street without the aid of a stoplight, I would have been T-Boned Vehicle problem has not been reproduced or confirmed by the dealer. 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.

My car just stopped in the middle of the road, and would not start again for a few minutes. Then is was in low power mode, no brakes either after that, found that problem to be a bad Vaccum pump, which G M didn-€™t even have, and a faulty Accelerator Pedal sensor !

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.

I was driving around 50 MPH and the car began to sputter and it wasn't getting in gas. It slowed down to 20 MPH and I had to stop on side of road. It behaved as if it were out of gas, but it had a qtr tank of gas. It would not start after I stopped it. I took it dealership and they still do not have an answer. There should be a recall on this. Numerous reports that are similar to my scenario.
