The shift to park is a problem it killed my battery because the car stays on and when I was driving the car turned off in the middle of turning causing someone to almost hit me this is the 3rd time that happened to me but the shift to park has been a problem since I got this car and Chevy does nothing about it

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.

The vacuum break booster went out. My check engine light came on and it said power reduced I’m not sure exactly. Because my power didn’t reduce but my car seems to be misfiring. Luckily I was going to be turning at a light and there was a few cars in front of me so I wasn’t going fast. As I got closer to the car in front of me I applied my breaks. They would not move and were hard and I gave it all I had to try to get my car to stop and thank god it did. Then my car stalled. I tried to start it and it just kept cranking but wouldn’t turn over, it also would not turn off till about the 3 times I push then button it finally turned off. Yes my safety and others would surely been at risk I wouldn’t have been able to stop in time if someone pulled in front of me or stopped suddenly I would not have been able to stop. If a child ran into the street I inn o way could’ve stopped! My step dad is a mechanic and he also ran a test on the check engine light and it threw 7 codes from this occurring. It didn’t give me no time it was very sudden. Once the engine power reduced appeared on my dash the check engine light came on and my car began misfiring in less then 45 seconds I went to apply the breaks and they were hard and I could barely stop. That was when I was almost about to be at a full stop so I wasn’t going very fast at all and I almost rear ended the person in front of me waiting to turn at the light. Then my car stalled. It all happened within 1 min 30 seconds from the warning my engine power was reduced but my engine power wasn’t not reduced either, and from then my check engine light and it all only took less then 2 minutes to all occur. It was sudden, no warning to think my breaks would not work at all and very quickly it could’ve been so much worse I can’t even imagine. Very alarming and fearful or my life and others from this occurring with no time to react and no idea what happened was going to. I will not buy a Chevy Malibu again and I was going to!

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.

I had a tire installed by a repair shop approximately one month ago. I recently discovered that the tire installed on my vehicle is the incorrect size. My vehicle requires size 225/55R17, but the shop installed size 245/45R17. This creates a safety concern due to improper fitment, which can affect handling, stability, and overall vehicle performance. I only discovered the issue after experiencing a separate flat tire and inspecting all tires on the vehicle. I contacted the business to have the issue corrected, but they refused to assist me. During multiple phone calls, both the manager and assistant manager were dismissive, unprofessional, and terminated the calls without providing any resolution. The incorrect tire remains on the vehicle, and the business has failed to correct their error.

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!

In 2020, I received multiple red recall notices in the mail regarding a safety issue. I scheduled an appointment with a Chevrolet dealership in Los Angeles and have a voicemail confirming the appointment. At the time, I did not follow through with ensuring the repair was fully completed, which I take responsibility for. However, the vehicle has continued to experience the same dangerous symptoms. My vehicle continues to display sudden “Engine Power Reduced” warnings while driving at freeway speeds. The car abruptly slows down and limits acceleration, forcing me to pull over and turn the vehicle off and back on to reset it. During these events, the steering wheel becomes extremely difficult to turn, creating a dangerous situation, particularly at high speeds. The vehicle also appears to have ongoing issues with the push-button start/stop system. Although I did not pursue the issue further at the time, I am now seeking to have it properly addressed because the safety risk remains and another family member is currently driving the vehicle. When I recently attempted to verify the recall status, both the Chevrolet website and other sources show no open recalls. However, the symptoms persist exactly as before, I cannot find the little red notices that were sent but I do have a voicemail from someone at Chevy confirming the appointment that I made because of the recall notices. This issue presents a serious safety hazard due to sudden loss of engine power and steering assist on highways. I respectfully request investigation into whether the recall was improperly marked as completed. Furthermore, can you provide me with the full recall and service history on my VIN including closed recalls and warranty repairs? I know recalls do not expire so I’m confused as to why no one wants to help me now. I appreciate your time.
