| Feb 2026 | UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Feb 2026 | ENGINE | I was driving on the freeway with my kids in the car at 60 mph and without warning I get an engine power reduced message and then my car losing power and starts dropping speeds down to 35 mph within seconds. I have cars speeding up behind me and I can't go any faster than 35 mph on the freeway so I am forced to quickly pull to the side of the freeway before I get hit. This was one of the post scariest situations for me any my children. I had to turn the car off and sit for awhile before I could start it back up and pray it made it home and didn't do it again. It has randonly done this for no rhyme or reason and no codes are showing when it's happening. I have no recalls on my car so this is something I believe Chevy needs to fix before someone gets seriously hurt. | Crash: No Fire: No | Unknown |
| Feb 2026 | POWER TRAIN | 2018 Chevrolet Malibu Premier with approximately 50,000 miles displayed a persistent “Shift to Park” message. The vehicle would not consistently recognize that it was in park, preventing the vehicle from shutting off properly and creating a safety concern. Dealer diagnosed a faulty transmission shifter assembly that was not sending a strong signal to the body control module (BCM). The shifter assembly was replaced at a cost of $611.31. This appears to be a known recurring defect affecting similar model year Malibus. Filing complaint to document safety-related failure. | Crash: No Fire: No | Unknown |

| Feb 2026 | SERVICE BRAKES,ENGINE | The Vacuum pump continues to go out causes code P1101. I have replaced it 4 times and people just in my town are fighting this code for dear life like me! It causes our brakes to barely work and make it completely unsafe to drive as the check engine light goes in and out for MAF sensor. It’s not safe. It needs to be recalled. It doesn’t matter if i buy the most cheapest part or expensive part. It has happened on multiple occasions where i replace it and within 2 months, its back on and does reduced power in the middle of me driving on busy roads. i’ve been almost hit and almost caused multiple accidents because I have to pull over. | Crash: No Fire: No | Unknown |

| Dec 2025 | SERVICE BRAKES | The brake booster unit, vacuum pump , brake light switch failed and malfunctioned and it is available. My safety and others on the road was at risk due to brakes being stiff and hard as a brick. Possibly nearly hit an other vehicles on the road.

| Nov 2025 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FUEL/PROPULSION SYSTEM | After diagnostic troubleshooting from DTCs on a check engine light, it was discovered that the brake vacuum pump connected to the engine was completely nonfunctional. Previous symptoms included stiff brake, loss of brake power at random brake periods which could have cause and accident with other drivers, and finally malfunctioning sensors attributed to the exhaust system. This also led the vehicle to be unable to pass state regulated Emissions testing because of the inability to maintain proper emissions levels. Brake Vacuum pump that was removed from vehicle to inspect and diagnose is still available for inspection. Recent findings show that Chevrolet/GM is aware of the issue in their vehicles but refuses to address or replace faulty brake vacuum pumps. It is a common problem amongst 2013-2022 Chevrolet Malibus. Vehicle that is in question was inspected by a certified mechanic shop with failed emissions test. Solid check engine light appeared once the brake had become harder to push and stop the car. OBD scans show DTC codes that were pertaining to MAF and MAP malfunctions in readouts and communications to the ECM. After further inspection, the ABS module had been acting as "backup" for hydrolic brakes system that had zero vacuum to power the brake booster, this could have caused the engine to stall, longer than normal stopping distances (stronger risk of rear ending other drivers), and multiple components and sensors to fail, requiring them to also be replaced. | Crash: No Fire: No | Unknown |

| Oct 2025 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM | 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 | Crash: No Fire: No | Unknown |
