2018 Chevrolet Malibu other reported problems

UNKNOWN OR OTHER

I own a 2018 Chevy Malibu. At approximately 57,000 miles, the original engine experienced a vacuum pump failure that resulted in catastrophic engine damage. The engine was replaced by General Motors under the vehicle's warranty. I then drove the vehicle for approximately another 52,000 miles with the warranty replacement engine. At that point, I experienced a sudden loss of braking while driving. My vehicle was again diagnosed with a vacuum pump failure, and the vacuum pump was replaced. Approximately one week after the vacuum pump replacement, the warranty replacement engine suffered catastrophic failure. The repair facility diagnosed cylinder #3 scoring and informed me that the engine required replacement. I was told that the engine failure was related to the vacuum pump failure. Because the warranty replacement engine was no longer covered under warranty, General Motors initially declined to cover the repair. Initially, neither General Motors nor the Chevrolet dealership was willing to accept responsibility for the issue. After continued discussions, General Motors ultimately agreed to provide partial financial assistance as a goodwill adjustment. However, I was still left responsible for paying a substantial amount out of pocket to purchase and install a third engine. The cost has created a significant financial burden that I have struggled to afford, especially because the repair involved a component that I was informed has a known history of failure. I was also informed that vacuum pump failures are a known issue with these vehicles and that General Motors is aware of the problem, although no recall has been issued. I am submitting this complaint because I have experienced multiple vacuum pump failures, two catastrophic engine failures, and have now required three engines in the same vehicle. This has resulted in significant financial hardship, loss of use of my vehicle, and serious concerns about the safety and reliability of this vehicle.

I’ve reported this problem but as I got into the repair their was far more damaged that was caused due to the vacuum pump. It took out my exhaust camshaft and sent metal through out and the timing needs replaced as well. A shop would rather total my car than what it would cost to fix. I’m attempting to fix it myself but have been without my car for months now. This is created such a hardship and the money it’s continues to take as more and more needs to be fixed or replaced as well as all the gaskets and screws that are only one time use as well as parts like my high pressured fuel line I mean this lost keeps going. I and to replace the water pump as well and all due to this vacuum pump that’s been reported and reported and nothing has been done this is outrageous that what’s caused is so much more then just a vacuum pump it can destroy your vehicle miles don’t matter the less or if you have more the pump goes out when it feels like it. Creating more issues then it should and potentially totaling out a vehicle as it’s been said mine should be. So I’m trying to fix my car to prevent losing it and it’s been one thing after another and such a nightmare. The fact that this issue continues to be ignored is unacceptable and a complete disregard to public safety due to the serious safety issue as mine I could barley get my car to stop the breaks were hard and unable to push down without basically standing on them to get into stop at only 7-8 miles per hour I was moving when the vacuum booster went out. Someone should not have to die to have this issue addressed and to be taken seriously and made right! I can’t believe nothing has been done and that it’s not required to have to address this issue with the severity it bring to one’s safety as well as public safety is beyond me. This is a major lawsuit and people’s lives and lovely hood should be taken more seriously and instead nothing is being done. It’s very concerning to think what has to happen for this to be addressed!

Shift to park error message appears on dash after turning off the vehicle. I have to turn back on the vehicle and take it out of park and shift it back and forth from park to drive then back to park to get the vehicle to turn off. This first January 2020. It was fixed in February 2020. This issue has started again in November 2025. The same error code and same results as the car won't cut off unless you push start it and shift out of park and back a few times.

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.

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.

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.

Ever since 2020 I’ve that shift to park issue. Luckily my car was under warranty the first time and was resolved only for the problem to reoccur again within 2 years. I then I got It fixed again in 2023 only for it to occur again less than a year later. I’ve had to buy a new battery because of this issue. What happens is I turn My car from the drive shift to park shift and push the shut off engine button. A message pops up on my screen stating “shift to park” the is in PARK. After 2-4 minutes of me waiting for he message to go off my battery is being drained. I refuse to pay hundreds of dollars again to get this fixed a third time only for it to return again. Please fix this issue. Myself and others with issue are seeking lawsuits for this defect

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.

My vehicle will randomly tell me to "shift to park". Happens at least daily. I bought my car in October 2024 I do plan to take it in with my limited warranty. I don't think I should have to cover a rental for however long it will take them to see it happen, diagnose the problem, possibly wait for part(s) to come in them fix it. On top of running the chance it'll happen again in the future and possibly have no warranty as well as rental fees. I think it's very wrong that GM won't recall this and refuses to just fix it all.

Car seat was inspected from the beginning of the purchase. The car seat through the seatbelt method was not sturdy enough and incorrectly leveled without the base even though the car seat claims to be for both uses (with or without the base). It claims to be for infants/ toddler (max 35lbs / max 32”) but my child outgrew after 1 year and was less than 30lbs / less than 30” I recently received a recall a few weeks ago. After years of purchasing. Plus the recall is before the expiration date of the car seat I own.

I'm getting Shift to Park error messages on my dashboard when I have already shifted my car to park. The gear shift is locked until the message clears or you wiggle the gear shift. According to GM Authority.com, this is a known issue for 2020-2023 Chevy Malibu cars that can cause the car not to start. My car is a 2018 Malibu so this issue has been occurring for at least 7 years now and has not been part of any recall, which it should be since it may leave people in a dangerous situation without being able to car their car.

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.
