general problems of the 2020 Chevrolet Malibu - part 2

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.

My vehicle Malibu2020. When I park sometimes it says shift to park sign. On dash board. The makes it difficult for car. To shut. Off I have to keep pressing the plus and minus sign on the gear shift to cut off.

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.

The contact owns a 2020 Chevrolet Malibu. The contact stated that while driving at an undisclosed speed, the engine revved loudly while coming to a stop. Additionally, the vehicle lost motive power while driving uphill. The vehicle was taken to the dealer, and the dealer confirmed that the vehicle performed as designed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact related the failure to technical service bulletin: 21-na-004 (continuously variable transmission). The failure mileage was 27,344.

Shift to park error, no power to car, reduced engine power, camshaft positioning error, brakes failed (completely went hard unable to press) almost causing crash.

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.

My vehicle displays a "shift to park" message on the dashboard, even when the gear selector is in the park position. This prevents the car from being shut off, and in sometimes, the doors may not be able to be locked. Not understanding the issue initially has thus caused me to have to replace my car battery numerous times for battery drainage.

I put the car in park and it says a message that says shift to park but I am in park already and now my battery keeps draining and the lights on shifter blink continuously when I’m in park if I click shift button the message goes away but I don’t think it should be doing this and I’m not the only person from what I have read.

A few days ago, when I put the car in park and turned it off, there was a message on the screen saying "shift to park. " it was in park. I could not get out of the car because it was still getting power. If I tried to lock the doors, it sounded the alarm. I had to turn the car on and off multiple times to get it to go away. It would've drained the battery if I'd left it. Who knows if it was really in park either. It's been doing it ever since. I called the dealer and they want $350 to fix it. The guy told me they've been seeing this on Malibu's and "now it's happening on the traverse models, too. " I've been reading online how this has been happening since at least 2016, but there is no recall. Why not?? this is dangerous and they're aware of the problem. They've issued service bulletins on how to fix it!.

Problems with my transmission for over two years, I’ve searched the website and have taken it to a dealership since. The vehicle has had a hard shift and problems to accelerate. The issue continues to get worse and my car has stopped while in drive, only allowing me to go backwards. It was within warranty and low miles. I was told that that’s what new cars do. Transmission fluid has always been full and topped off. In order to know what is wrong I am told I would have to pull my transmission and was suggested to replace it because it would be an easier fix. The steering also pulls. I’ve contacted the dealership and was told to contact chevy for recall and since it was not in their data they could do nothing for me.

The shifter gear control/ shifter assembly keeps failing on and off. It’ll give me a warning shift to park. It did this while drive on a major highway then my car loss all power as I was in the second lane causing so much safety concerns. It is also alerting me when I’m in park now that I need to shift to park more frequently. Extreme issue.

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 contact owns a 2020 Chevrolet Malibu. The contact stated that while driving at various speeds, the vehicle would intermittently hesitate and stall as both the traction control and check engine warning lights appeared on the instrument panel. Once the vehicle stalled, the contact would have to wait a few minutes before a successful restart of the vehicle. The vehicle had been taken to the dealer on multiple occasions where they have been unable to replicate or diagnose the failure. The contact has had the pistons, battery terminal, transmission, and wiring harness replaced; however, the failure persisted after each repair. The manufacturer was notified of the failure and referred her to the NHTSA for assistance. The vehicle had yet to be repaired. The failure mileage was unknown.

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.

1. Something under the car hood is making a whistle type noise. Is available for inspection. 2. I don't know if it is a safety risk. 3. The problem has not been confirmed by the dealer. 4. The vehicle was inspected by the dealership. 5. There were no warning lamps on or anything. The whistling appeared under the hood around may 23,2021. 6. The whistling appears under the hood of the car after driving it approximately 30mins with the air conditioner on. 7. I took it to the dealership and they seem resistant to fix the problem!.
