The gear shift DOES NOT recognize when the car is in park. The entire transmission was replaced last year under warranty, but the gear shift is not covered. When putting the car in park, the screen shows -??P-?? for park, but also displays -??!Shift to Park!-?? and beeps nonstop. When this issue first happened, a simple jiggle of the gear shift handle would make it go away. Over time it turned into yanking the shift, then moving from park to drive and back again over and over, then driving around the parking lot and trying to turn it off repeatedly, and now today the car did not shut off for 3 hours despite all of my efforts. I have been late to work MANY times, I have drained my battery several times, and my anxiety has never been higher with this car. The engine turns off, but the battery stays on. My husband had to unhook the battery entirely from under the hood for it to turn off after THREE HOURS. After doing research, I found it would be over $300 to replace the entire assembly (plus labor), and 2020-21 models are not covered under this recall affecting LITERALLY EVERY OTHER MALIBU IN EXISTENCE. PLEASE!!!!!!!!!!!!!!! Fix the problem!!! recall this PLEASE! I cannot afford to fix this myself (with no guarantee it would even fix the issue) and cannot afford to buy a different car. This is ridiculous!!!!!!!

When this issue first started. My display said put the driver window down then back up. Seconds after following this prompt my car display says shift to park. I was already in park and had shut the engine off. When I open the driver door my horn beeps 2 times and my start button is yellow not allowing me to turn the vehicle completely off. As the days pass my 2020 Chevy Malibu now says shift to park Everytime I go to get out of it. Today when this happened I was trying to get it to read my vehicle was in park for about 20-30 minutes. Finally after wiggling my shifter the display disappeared.

What component or system failed or malfunctioned, and is it available for inspection upon request? Car had numerous times of completely turning off mid drive and was taken into a certified dealer for inspection, with a conclusion that nothing was wrong. The transmission has failed (03/22/24) and has been recently replaced upon diagnostics from certified dealer. 2 days later after receiving vehicle from transmission fix (04/20/2024) the vehicle began to experience Electronic Stability Control errors and caused steering assist to also fail mid drive and cause a locked steering wheel. These errors occurred (04/22/2024 and 04/23/2024) How was your safety or the safety of others put at risk" All of these factors explained above have happened during a drive and has put me at risk of numerous accidents that could have been fatal. The most recent one dated above, happened in the middle of the road with little to no where to safely pull over and restart the car system. Again, could have resulted in a fatal accident. Has the problem been reproduced or confirmed by a dealer or independent service center? Electronic errors of the vehicle shutting off was unable to be reproduced or confirmed by dealer. Transmission failure has been confirmed and replace. ESC and steering assist has yet to be confirmed from dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This vehicle has been inspected by numerous dealers and or auto shops with little to no help in fixing any problems. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" I also have warning lights from all times I have experienced failures or warnings from the vehicle and will be providing this.

Electrical issue, Continuously losing communication to EBCM causing the car to go haywire with warning lamps on the dash board and then it brakes on its own, while driving on the highway at high speeds. This is very scary and extremely dangerous and this could eventually cause a serious accident. This has been occurring for 3 months now. I-??ve had the car serviced 3 times within the last 3 months, costing me a lot of money but with no real resolution. Problem has been confirmed by independent Mechanics, they stated the codes are a loss of communication to all control modules, they then reset / reprogram modules, which is only a temporary fix because it always happens again.

The steering assist is reduced will come on. The car randomly turns itself off and back on when at a stoplight; this has happened four times now. I worry that it will shut off and not restart creating a hazard on the road.

I was hearing a grinding noise when applying brakes so i had a mechanic change my brakes. He said they didnt need changing but i had him change them anyway. The noise didnt stop but we wasnt sure why it was making the noise. While driving down the highway, the break pedal became to hard to press. At that point I was in heavy traffic and had to use my emergency brake system to avoid collission with multiple vehicles. Upon taking my vehicle to the mechanic it was observed the vacuum pump had broken inside the motor. After the mechanic changed the part and cleared the broken parts out of the motor, within 6 months my breaks are acting funny again making loud noises when applying brakes. I'm terrified to drive long distances.

The power train may be defective. The auto shut off on the vehicle completely shuts off when you stopped at a red light. The entire vehicle restarts, and then 12 lights appear on the dashboard. The car starts shaking sometimes when it's being driven. The vehicle is currently being looked at, at the dealership. I was told that the diagnostics is reading 19 codes and misfires.

While driving on expressway, vehicle slows down suddenly. Service ESC, power steering, and engine light comes on and car tuns off. This has happened 8 times in two years with no fix from GM. This happens with no warning the car just stops driving and loss of power steering occurs. The dealership has tried to fix 8 times now with no real fix to the issue.

I was driving down the hwy and all of a sudden, my engine lost power and my brakes harden. I could not brake and nearly lost my life and my sons.

- Oxford , MS, USA

The vehicle goes to ESC mode loses power an all gauges go frantic. All warming lights come on and the brakes go stop working. Speed decreases while in motion, unable to go past 40 mph. Warning messages such as put car in park will appear while the car is in park, steering unstable, low fuel a many others. This is a hazard and I only had the vehicle for 1 year, however I reported the first issue in April 2023 to dealer of purchase an no fix at this time.

I purchased a 2020 Chevrolet Malibu with 38,000 miles. I experienced a faulty air vacuum pump (first experience was at 45,000 miles and was replaced in August of 2021, two months after purchasing the vehicle in June of the same year), and then the replaced air vacuum pump again in February of this year (2023). This issue being brake related was unsafe. I experienced an intermittent reduced engine speed message on dashboard, with immediate reduction of speed down to 20 mph or less while driving. This made me and others unsafe. I experienced brake booster failure, among other issues stemming from all aforementioned. The car is now said by dealership to have indication of an internal engine issue and affected PCV lines dealing with a defective orifice (Kiriacopoulos, et al. v. General Motors LLC, Case No. 2:22-cv-10785, in the U.S. District Court for the Eastern District of Michigan) The car remains at a dealership and has now been there for over 30 days. There was no warning lamps, messages prior to the air vacuum Pump/Brake booster issue. I got in the car to try driving, and it was hard to push the brake with foot, so for I knew something was wrong. In taking it in to service, was when it identified to be that issue. Those issues have been manufacturer inspected (dealership) and confirmed. I experienced these issues since purchasing the vehicle in June of 2021. I believe that GM knows of these issues and has put me at risk on the road, along with some other symptoms of the car failures that are also well documented, and that GM is aware of, with no recalls. These car parts/issues put me and others in further danger, the car's air vacuum pump and brake booster affecting car's ability to operate, damaging other parts (Johnson vs. GM).? Consumer rights to be protected and safe are at risk, not deserving to have faulty auto parts sold, further exacerbating issues with the car being dangerous on the road with defective brake related parts, and rendered inoperable.?

Since last year I am having this problem in this car, even after parking the car, it is giving an error of "shift to park', I have already taken it to the car dealership twice to fix this problem and still the problem is not getting fixed in the car. Not even that I live in California and while coming back from Vegas last year, this car suddenly stopped working while on the freeway, luckily I was near truck station so I stopped the car. This is a new car and I didn't even drive 36000 miles on it and it is giving me problems. This car is a serious problem and I would request nhtsa to please step in and take action regarding the manufacturers.
