| Nov 2022 | POWER TRAIN,SERVICE BRAKES,FUEL/PROPULSION SYSTEM | Brake Power Booster, vehicle not starting. Not catching, brakes when completely out couldn’t stop | Crash: No Fire: No | Unknown |
| Nov 2022 | POWER TRAIN | When I shift the car into park the dashboard gives me a message that the car needs to be shifted into park. This is an intermittent problem and does not occur every time I shift to park. When I get this message I am not sure if the vehicle is actually in park. The problem has been diagnosed by the dealership. The defective part has been replaced by the dealership. The only message I received is the one on the dash stating to "shift to park". | Crash: No Fire: No | Unknown |
| Oct 2022 | UNKNOWN OR OTHER,ENGINE | Engine reduced while driving | Crash: No Fire: No | Unknown |
| Oct 2022 | STEERING,ENGINE | 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, | Crash: No Fire: No | Unknown |
| Oct 2022 | VEHICLE SPEED CONTROL | 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 | Crash: No Fire: No | Unknown |
| Oct 2022 | UNKNOWN OR OTHER | I am the first owner of a 2018 Chevy Malibu. This car was displayed on the showroom floor. Shortly after purchasing this vehicle a new “computer” was needed. Following the new computer, my Chevy Malibu would be at approximately 70MPH and would “engine lock” its speed causing it to suddenly go from 70MPH to 20MPH while on a freeway. During this time my Chevy Malibu would reeve at approximately 5,000 RPMS and would not go over 20MPH. I brought this to GMs attention and they appeared to have very little concern. As a mother of two and a Police Officer I was very upset with GM. My vehicle has “engine locked” itself multiple times and has been towed to a dealership. Fast forward, my car, will not turn off and I’m unsure if it is going into “park”. I have replaced the “wire harness” or “transition switch” where my shifter is located. It has been approximately two months since replacing this part. My Chevy Malibu is once again not going into park and will not turn off. I am concerned my car will roll away while I am at work or out in town and cause serious injuries. GM does not seem to care about these issues. Issues being, the “shift to park” and the “limp mode” issues that my car continues to have. As a Police Officer I know that this could be VERY dangerous and I would like a solution to this issue or a new vehicle. This vehicle is not safe. | Crash: No Fire: No | Unknown |
| Oct 2022 | UNKNOWN OR OTHER | Shifter sometimes does not recognize it was put in park. Trouble getting it to recognize park and turn off electronics. Class action law suite may be in the process with multiple models. Happened multiple times and more frequently. | Crash: No Fire: No | Unknown |
| Oct 2022 | POWER TRAIN,VEHICLE SPEED CONTROL,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Oct 2022 | ENGINE,FUEL/PROPULSION SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Oct 2022 | UNKNOWN OR OTHER,SERVICE BRAKES,ENGINE | 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. | Crash: No Fire: No | Unknown |

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 ! | Crash: No Fire: No | Unknown |
| Oct 2022 | ENGINE | I was driving app. 41 miles per hour in heavy Friday traffic on 10/7/2022 and the check engine light lit up and the car dropped to about 20 miles per hour and would not pick up speed. The rpm was staying on about 3000. I pulled over and called my husband. We set for awhile and restarted the car and the light went off and it drove as normal | Crash: No Fire: No | Unknown |

| Oct 2022 | ENGINE | The contact owns a 2018 Chevrolet Malibu. The contact stated while driving approximately 65 MPH, the vehicle stalled, causing the power steering and power brake functionality to become inoperable. The contact stated he was unsure if any warning lights were illuminated. The contact had managed to coast off to the side of the roadway. The contact stated that several attempts were needed to restart the vehicle and he was able to drive the vehicle to his destination. The contact stated that the failure started off as an intermittent failure, but gradually had become a constant failure. The contact stated that the failure recurred and the vehicle had to be towed. The contact had taken the vehicle to a local dealer on several occasions to be diagnosed; however, the mechanic was unable to duplicate the failure. Additionally, the contact stated that the radio would randomly switch through the preselected stations. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 75. | Crash: No Fire: No Towed | 75 |
| Oct 2022 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL | 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). | Crash: No Fire: No | Unknown |
| Sep 2022 | POWER TRAIN | When I put my 2018 Chevy Malibu in Park i receive Shift to Park' error message. I have to keep pushing on the gear shift to get it to go into park mode. It happens frequently. I have seen numerous reports of this same problem. The last time it happened was around 9/19/22, but it has occurred since I purchased the car in 2019. It began when the car only had around 40,000. There should be a recall from GMC/Chevrolet. | Crash: No Fire: No | Unknown |
| Sep 2022 | ELECTRICAL SYSTEM | On 9/22/22 I drove 2018 Chevy Malibu about 3 blocks and low fuel light displayed. The gas needle went past E. I had about a quarter tank when I last drove it. I drove about 2 miles, going 50 MPH and it began to sputter and reduced speed to 20 MPH. Very dangerous situation, but I pulled off on side of road. When tow arrived driver got in car and the gas needle moved back up to almost qtr tank and no low fuel lights or warning sound was generated, engine turned over but it would not start. Had it towed to gas station and put gas in it, still would not start. It was not out of gas. The reading was incorrect. Towed to dealership and they still have not found the problem over a week later. Stated it could be an electrical problem. Electrical service repair tech is checking it. I have seen similar scenarios reported on this site. GMC/Chevrolet needs to do a recall. This is a dangerous situation. Luckily I wasn't on a very busy road. | Crash: No Fire: No | Unknown |
| Sep 2022 | UNKNOWN OR OTHER,ENGINE,FUEL/PROPULSION SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Sep 2022 | ELECTRICAL SYSTEM,SEAT BELTS,FUEL/PROPULSION SYSTEM | 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. Mine I'd always broke down and no one will help me. I pay 475 a month for a car that doesn't work and is dangerous to me and my special needs child and everyone around us. Please do something. | Crash: No Fire: No | Unknown |

| Sep 2022 | UNKNOWN OR OTHER | Malibu would not recognize shift into park. This happened multiple intermittent times. Had to take it to dealership to be repaired on 9/6/22. While waiting for my Malibu to be repaired I was talking with a gentleman who had his Malibu in for the SAME problem. He stated his friend had the same thing happen on his Malibu.
