2018 Chevrolet Malibu electrical problems

ELECTRICAL SYSTEM

A software error in 1.5L turbo model disable fuel injectors, preventing the engine from starting or causing a sudden stall while driving. It’s been confirmed to be an previously opened recall that was fixed by previous owner. But, is happening again to me. Yet I’m being told It has been closed and cannot be fixed unless I pay out of pocket. There are warning signs that pop up like reduced speed while I am driving etc. which reduces my speed and is incredibly unsafe.

I went to put my car in park and it was saying "Shift to Park" on my dashboard even though I was already in park. I know that there was a lawsuit that was won for this very defect but my car is not recalled for this and I feel every Malibu should be especially if almost every Malibu is experiencing the same issue Nationwide. It cannot be a coincidence. Also I have been having issues with a knocking noise on the back of the car when I am driving and I'm being told it's also another common issue with Malibu's known as the Knuckles that need replaced which are not cheap. If these are common issues on every Malibu then every Malibu needs to be recalled for the issue to be fixed not just certain ones. My Malibu has not had one recall but has had the same issues that other Malibu's had with multiple recalls done.

My 2018 Malibu is stalling, it is covered under Recall N192221960, and the dealer is refusing to properly scan or fix the issue. They did the recall and the car is still doing the same thing but worse.

The check engine light keeps coming on and off with a warning that the engine power is being reduced. The dealership's service center can't locate the issue. The car's traction warning went off and the car's speed was reduced while driving. This happened twice in the same day. When you shut the car off and turn it back on the warning goes away and the car drives normal. This is very unsafe. Had this happened on the highway there could have been a serious accident.

The rear camera comes “loose” and does not register all the time. It seems to be a simple electric issue; possibly an electrical short. I believe it can be easily “fixed” (temporarily) by opening the trunk and running fingers over the camera, it should not happen. I purchased my Malibu new and seldomly drive, approximately 25k miles. I maintain proper maintenance and ensure cleanliness to avoid dust or particles inside the camera or electric components. This should not happen. The wiring should not become loose nor cause the camera to turn off. Chevy dealerships do not acknowledge the issue and expect the car owners to repair the entire electrical system. Definitely should be a recall item!

The backup camera for this vehicle is starting to fail and the view is blurry. Additionally, it seems that this also is affecting the rear traffic alert as I almost crashed into someone at a parking lot when trying to back out of a space. I will soon have no rear camera or cross traffic alerts.

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

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.

ENGINE POWER REDUCED light keeps coming on while driving and the car stalls and won't go over 20mph. Several repairs later and it is still happening almost daily. It has nearly caused an accident several times. This needs to be fixed and a recall for the issue needs to be issued by Chevy. With this many people experiencing this problem, why isn't Chevy obligated to address the issue?

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.
