2018 Chevrolet Malibu Electrical System Problems

Shift to park indicator comes on after shifting parking gear to park. Car fails to detect that it is in park even when it is.

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 vehicle shut off in the middle of the street. I had to get it jumped to start again. There was a fuel leak. Car is still smelling like fuel after getting it repaired. The vehicle doesn't alert if your close to a car or anything

I get a engine power reduced warning and check engine light is on for 3 start cycles and goes away. Auto Start/Stop after stopping, lights flicker and power is slow to come back on upon auto start and I get a power steering reduced warning.,

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

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.

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.

The mechanic discovered that the Battery Control Module harness had been damaged by water intrusion inside the vehicle. This damage prevented the vehicle from powering on, rendering it completely non-responsive.

I have searched the prior recalls and I’m having the same problem that were said to be fixed. I would like the car check again for the recalls that said to be fixed and checked for all reacalls . The car turns of unexpected without warning . At random times the low power mode is always on and when I push down in the pedal it doesn’t respond well at all . I have invested countless money into fixing issues with this car .

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.

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.

When parking it says shift to park even when I’m already in park. The dealer says it’s the shifter however after seeing numerous other vehicles with this issue I believe it’s electrical

SERVICE BATTERY CHARGING SYSTEM NOTE CAME ON, JUST REPLACED THE ALTERNATER AND GOT A NEW BATTERY PUT ON. EVERYTHING ELSE IS GOOD AND THIS KEEPS COMING ON.

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.

When I turn my vehicle off, it displays “shift to park” I am trapped in my car because it does not turn off all the way and the door will not lock. I have to wiggle and re-crank several times to attempt to get my vehicle to shut off. My battery has gone dead several times because I simply couldn’t turn the car off with the shift to park displaying.

This car has the shift to park issue that was under a recall for 2016 to 2019 chevy malibu. However gm refuses to put my vin in the system so this issue can be repaired. This is a 2018 malibu which should have been on that recall list.
