2020 CHEVROLET MALIBU Complaints

Malibu displays “shift to park” message because of a known issue with the electronic shifter. The shifter fails to detect when the vehicle is properly in park, requiring adjustments until the system recognizes the correct gear position. Informed by dealer to just move gear shift back and forth until message clears then can turn off vehicle. This can take up to 10-15 minutes. Also advised to keep emergency break on or vehicle could roll away!!! Apparently this is a known issue per the mechanic. Said the electronic shifter may or may not resolve this and if it doesn't resolve the problem can also affect the transmission.

“shift to park” message appears after car has already been shifted to park. Will not allow car to be turned off as the car thinks it’s still not in park. Known issue with earlier models of the malibu that warranted a recall of models 2019 and before. Seems like this is a continued issue in the 2020 model

I am writing to formally report a critical safety issue with my 2020 Chevrolet Malibu, which resulted in a severe accident and posed significant risks to my safety and the safety of The issue involves the brake vacuum pump, which failed while I was driving. The component is currently with the vehicle, which is stored in a parking facility, and is available for inspection upon request. The failure of the brake vacuum pump caused a sudden and complete loss of braking power while I was driving. This malfunction put my life and the lives of others at immediate risk. On the first occasion, in April, I narrowly avoided a serious collision. Four weeks later, I experienced a second instance of brake vacuum failure, which led to a severe accident. The inability to stop the vehicle safely was directly caused by this malfunction. I contacted General Motors (GM) in April 2024 to report the initial brake vacuum failure. At that time, the issue had not yet been reproduced or inspected by a dealer or service center. Following the accident, I have been unable to confirm whether GM or any other party has The vehicle and component have not been inspected by the manufacturer, police, or insurance representatives since the accident. I reported the issue to GM prior to the accident, but they have not provided any assistance or resolution. Prior to the initial brake vacuum failure in April, I did not observe any warning lamps, messages, or other symptoms indicating a potential problem. The failure occurred suddenly and without warning, making it impossible to anticipate or avoid. This situation is incredibly distressing, and I believe the brake vacuum pump defect poses a serious threat to public safety. I urge the NHTSA to investigate this issue thoroughly and take any necessary steps to ensure the safety of other drivers who may be at risk.

Shift to park issue . When the car is shifted to park, the system does not recognize the car is in park mode even though the stick is in Park. It starts beeping and that dash board screen shows SHIFT to PARK. It happened several times in October 2024. The dealer says it does not cover under the warranty and it has on 20000 miles and bought in 2021.

Faulty Vacuum pump caused catastrophic engine failure. The vacuum pump exploded cracking the cam shaft sending metal shards into the engine. $12000.00 to repair and mechanic will guarantee the work because the replacement vacuum is an only OEM part. I was having braking problems prior to the vacuum pump failing. The brakes would intermittently freeze up and I couldn't get the car stop and had to use the emergency braking system to stop vehicle. Car is still at shop I can't afford the repair and I'm am still paying finance company for car. I have a disabled child and am low income. This has put hardship on me as I live in an area that does not provide public transportation. I don't know what to do.
