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.

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.

After you shift the car into park and shut the motor off, the car flashes a warning on the instrument panel to shift the car into park. Which it already is. Appears there was a recall for this for 2016-2019 cars, but not the 2020 year like mine. Happens consistently.

Vehicle through a "service engine" and lost partial power. The vehicle slowed considerably and was not able to accelerate as expected. Fortunately, this was rush hour traffic and it was slow. Normally, the traffic moves at 60 MPH plus or minus 5 MPH. The loss of power on I10 can be extremely unsafe. The dealer revealed that our car had a scan code P0299. They cleaned the Thottle Body and stated it was the likely problem. However, they said they tested the crank case pressure and it was at 0 PSI, instead of the expected vacuum. There was no indication, that crank case pressure or the PCV was the root problem. I pointed out that crank case should be measured in INH2O. I think they mis diaganosed and were trying to lead me to replace the PCV, and ultimately the turbocharger itself. I think it is probably a sensor or perhaps another component. I took my car away from the lot and will report any other incidents or findings.

Shift to Park Alarm will not stop beeping. Looked into it on the internet found it to be a known issue with GM. Can prevent the doors from unlocking and would drain battery and annoyance. Replaced shifter assembly at a cost of $567.28 I believe GM knows of the issue and should recall the defective parts. I am making this complaint on behalf of my 85 year old Mother that purchased the 2020 Malibu with the remaining 3 year/36000 miles warranty. In November of 2022 she had the Alarm Shift to Park come up and would not stop. I return the car to the shop where she purchased it, expecting the issue to be covered by warranty. I found out the car was put in service in August of 2019 making the warranty expired. The mechanic that replaced the shifting assembly explained the problem to me and gave me the defective part. When researching the problem I found that GM it aware of the issue and should recall and fix the problem. I have contacted GM but they refuse to reemburse me. I filed a complaint with the BBB and I see that there is a class action lawsuit over this issue. I have my complaint on file in hope that GM will voluntarily recall or be forced to if enough people complain.

I need my pistons and rings replaced. My car only has 57,000 miles. My car has been diagnosed with excessive piston blowby from 2 different independent service centers. Both times I have been to Chevy to get it fixed under warranty, they-??ve charged me $200 for diagnostics each time and told me it is my PCV valve that needs fixed. I had them fix my PCV valve and I still have excessive piston blowby. Chevy just wants to keep bringing my car back in for more diagnostics. I have spoken with GM customer service 2 times and somehow every single time I give them my VIN they hang up. My car is a 2020 with only 57,000 miles on it. There-??s absolutely no reason why I should need all new pistons and rings and why Chevy service centers won-??t just get it done! I have diagnostic reports, receipts, and videos of everything.

The vehicle will randomly shut off while driving. All warning lights light up on the dash and notification of "reduced steering" pops up. Taken to the dealership and has been there for 19 business days. They will fix a component, I have picked it up twice and it has shut off before I could even get home forcing me to tow it back. This last time they were bringing the car around and it shut off in their own parking lot before they could even give me the keys. Every time they run diagnostics it's a new code. Vehicle is unsafe to drive due to shut-off and loss of steering.
