Electrical System owner reports: Chevrolet Malibu years in the records

The records describe a problem worth checking before purchase.

“I was told the bcm on my vehicle is bad. It cause my car to go all out of wack. Multiple warning lights come on (ESC, ABS, power steering, check engine), the gauge controls flutter, my gear shift clicks on and off, the car has even shut down on me in the middle of traffic, wouldn’t start, wouldn’t shift, basically wouldn’t move at all even when it did start. How would a bcm shut down my whole vehicle?”

“Transmission misfiring.”

“I have a problem with parking, the warning comes on,”Shift Into Park” knowing that I’m in park, so it’s not registering. Have to move the shifter a couple of times before it comes off. My check engine light stays on and then comes off a week or two later and then comes back on and no code comes up, so I’ll clear it or let it clear itself.”

“I am submitting this statement to report a recurring safety and reliability issue with the 2022 Chevrolet Malibu. The vehicle intermittently displays a “Shift to Park” message when the car is turned off, even though the gear selector is already in the Park position. Due to this malfunction, the vehicle’s system does not fully shut down as intended. As a result, electrical components remain active, leading to repeated battery drain and, in some cases, a completely dead battery. This creates an unreliable operating condition and leaves the vehicle unable to start without external assistance. This issue presents both a safety and usability concern. The vehicle may become inoperable without warning due to battery depletion, Drivers may be stranded in unsafe or inconvenient locations, The system’s failure to correctly detect the Park position raises concerns about the reliability of the transmission interlock and shutdown systems. The problem appears to stem from a fault in the gear position detection or related electronic components, rather than user error. The condition persists despite ensuring the vehicle is properly shifted into Park. Given the potential for widespread occurrence and the risk of unexpected vehicle disablement, I respectfully request that this issue be investigated for a possible defect and considered for a recall or service campaign.”

“When shifting my car into park the vehicle did not recognize that the gear was indeed in park. I would get a message saying “Shift to Park” and I could not fully turn my car off. This problem made me feel unsafe as I didn’t know what to do when it wouldn’t turn off. My battery could have run down and I would be stranded. In researching this problem GM was sued for the very same problem in earlier models so I am incredulous that they have not fixed this issue or initiated a product recall. I had to have an internal switch replaced at a GM dealer service center at my expense and the car only had 15263 miles on it.”
