2018 Chevrolet Malibu

The contact owns a 2018 Chevrolet Malibu. The contact stated while the vehicle was in a park, he noticed that a warning light indicating that the vehicle was not in park was illuminated. The contact also stated that while driving at an undisclosed speed, he heard a knocking noise at the rear-end of the vehicle. The vehicle was taken to the dealer where it was diagnosed that the shifter cable needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 21,000. The VIN was not included.

Please see General Motors Technical Service Bulletin 19NA206.745.57. There is a problem that occurs with the transmission shifter. Even though the driver has shifted into Park, the switch inside the shifter assembly triggers a message "Shift to Park." At times, the ignition cannot be turned off and the driver has to keep trying. My Malibu was affected by this issue.

When I shift the car into park the dashboard gives me a message that the car needs to be shifted into park. This is an intermittent problem and does not occur every time I shift to park. When I get this message I am not sure if the vehicle is actually in park. The problem has been diagnosed by the dealership. The defective part has been replaced by the dealership. The only message I received is the one on the dash stating to "shift to park".

What component or system failed or malfunctioned, and is it available for inspection upon request? A defect in the cam shaft solenoids causes a notice that "Engine Power is Reduced." At that point, the engine begins to struggle to accelerate from a stop, and from increasing speed while on the highway. How was your safety or the safety of others put at risk? The unpredictability of the defect and its affect while driving poses a large threat to safety, particularly on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealership service rep not only confirmed the defect, but also confirmed that the issue persists across multiple GM models yet no recall exists. Again, this is a KNOWN defect with GM engines, as confirmed directly by the dealership. Despite this, no remedy was offered, I was told it's neither covered by my manufacturer's warranty or recall. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. I was given a video explanation of the issue and also told directly of these persistence of the defect across multiple lines. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning prior to the failure. The defect and "Engine Power Reduced" message both first presented in March of 2022, less than a year into my ownership of the car -- and while my car was still under its 60,000 mile warranty.

When I put my 2018 Chevy Malibu in Park i receive Shift to Park' error message. I have to keep pushing on the gear shift to get it to go into park mode. It happens frequently. I have seen numerous reports of this same problem. The last time it happened was around 9/19/22, but it has occurred since I purchased the car in 2019. It began when the car only had around 40,000. There should be a recall from GMC/Chevrolet.
