2020 Chevrolet Malibu Complaint Log

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.

On [XXX] I was driving to work and my check engine light came on. Immediately after this I was completely unable to brake. My brake pedal became so stiff and impossible to press. I very narrowly avoided an accident. I had the car towed to an auto shop where I was informed that I had a vacuum pump failure that essentially exploded and destroyed my cam shaft and shot fragments of metal into my engine in the process. I was quoted over $12,000 in repairs. After receiving this quote I began searching online to find what could have caused this to happen. I stumbled upon a class action lawsuit for this EXACT same thing (plaintiff [XXX] ). In addition to the suit there were 12 PAGES of comments from other Malibu owners who have experienced similar issues with their vacuum pump and braking system. This issue is also noted on MANY car repair forums, Chevy owner forums, YouTube repair videos etc. Please note that when I received the check engine light on 9/5 this is the first and only time I had any indication of a potential problem with my vehicle. In the year and a half that I have owned the car there has never been any issues, warnings or check engine lights.

When I turn my car off it tells me to shift to park when it’s already in park

This car has problems when shifting to PARK. Sometimes it doesn't recognize its in park and wont shut off. There is a recall on this but when I look up my VIN it doesnt show a recall for my exact vehicle. Am I still able to get this fixed under the recall?

I was driving down the road and the car started slowing down and even when I would give it gas wouldn’t accelerate. After pullling over and allowing the cars behind me to pass I tried to pull back out into traffic and the car would not engage into gear. When giving the car gas it didn’t move. I shifted the transmission into park and tried shifting into every gear including reverse and the car wouldn’t go anywhere I had to sit in the road for about 20 minutes then the car shift very hard into drive and began accelerating. Now when trying to drive it every time it stalls out either when first trying to back up or take off or decelerates while driving down the road making me fearful for my life due to being hit from behind sue to no notice or warning before the car decelerates

My vehicle started to show a shift to park message. I took it to Firestone and they replaced the switch. This started happening again 2 weeks later. It is worse this time. It takes me several minutes to get my car to acknowledge that it is in fact in park.

My vehicle will not shut off. It states "shift to park". Sometimes it takes 30 minutes of trying to get the car to shut off. Since this began, we were on a road trip, it's causing issues with accelerating on the highway & I believe it's damaging the transmission. 2020 Chevy Malibu had other models under recall for this same reason. I called Chevy dealership & they said they cannot help me. They told me to contact General Motors. I have a [XXX] baby, I'm [XXX] & lost my job after maternity leave. This should be resolved as it's causing me anxiety to drive it with my child in the car. Please help me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I had a constant message when turning off the car to shift to park. When the car was off, it would say shift to park on my screen. Apparently there is a recall for this, but my VIN number was not included in the recall. I had Several instances where I had been driving and my brakes locked up, and it caused my car to stall out. I would have to turn my car off and back on and sometimes it would work and that message would go away to shift to park. I eventually had to get a new transmission on a four-year-old car.

The problems listed in my vehicle are the following • U0073: Control Module Communication Bus A Off • U0100: Lost Communication With Engine Control Module • U0121: Lost Communication with Electronic Brake Control Module • U0140: Lost Communication With Body Control Module • P0700: Transmission Control Module Requested MIL Illumination I believe this is due to a bad design in the wiring. Also the electric brake vacuum broke which is a common problem.

Yes my car has just started to displaying a shift to park message on the message center when you shift the car into park. I know there are recalls on 2016-2019 Malibu and now it’s doing it on my 2020. Come on Chevy

So far it is only once in a while when I shift into park and turn off the engine the ‘Shift to Park’ message will be displayed in the dash. Sometimes I can jiggle the shift lever a little to make it go out, other times I have to start/stop engine , shift out and into park several times to make it go out. I don’t want to leave the vehicle without making sure it’s in park. I read in another complaint that the doors won’t lock, and that it goes into accessory mode and could drain the battery down if left that way, but I did not check if that happens on my vehicle. It just started doing this a few weeks ago. I have not contacted the dealership yet, but I understand that GM has put out a recall on the Malibu and other models concerning this issue. I am hoping it will cover my VIN. number soon. Thank you for taking time to read my complaint.

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.

After pressing the button to turn the vehicle off the message board displays a "shift to park" alert. The vehicle will not completely turn off until you clear the message. I do not know how to clear the message so the vehicle will completely turn off and to keep this from happening again. It requires me to turn the vehicle off, restart it, put it in drive, stop, put it in park, then turn it off. Simply turning the vehicle off and back on does not clear the message. It takes me at least 3 tries to get the vehicle to finally turn off normally without the "shift to park" message. This does not happen every single time when I turn the vehicle off and at no particular frequency. It is very annoying because it happens when you least expect it. When you are on a time schedule you do not have 5-10 minutes to re-start and turn off the vehicle again numerous times to get the message to disappear. It is also not good for the engine and transmission components to keep having to go through this process. This issue has been occuring for approximately 1 year. I thought it was fixed because the message stopped coming up for awhile but the issue is occurring again at no particular frequency. Please check into this and issue a recall. From what I can see, I am not the only one having this issue.

The brake pump in my 2020 Chevrolet Malibu LT 1.5 malfunctioned on 05/25/2024. My car had approximately 85,193 miles on the odometer when this occured. I was driving down the interstate on 05/25/2024 when I went to apply the brake pedal and it was completely stuck. I had to swerve into the grass on the side of the interstate to avoid collision. After I had the car towed home, I had a mechanic run a system diagnostic test on the car which showed an error/defective code for the brake pressure sensor.

Car is indicating "Shift to Park" after placing in park and turning off. Unable to lock vehicle. Lights remain on. Took vehicle to dealer though it's a widely known issue I will be required to pay? Transmission was replaced at 35K due to manufacturing defect. Every 20k miles I'm going to have more transmission issues? It's just not right!

The TMC and MAF sensor goes out within 100,000 Mileage

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.

P1101 AIR FLOW SYSTEM! I replacement almost every things ,but still have the p1101 code Park to Shift!

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.

Shift to park detected when I have gear in park

This is a 2020 Malibu with only 18,000 miles on it now. We are having intermittent loss of power. Car will be moving fine when suddenly it looses power when pulling into traffic from a stop. It has also happened on the highway(right after leaving the dealer service department) when going to pass a vehicle…all of a sudden power drops and rpms go up and car slows up. When it suddenly happens, pulling into traffic is very slow. The only way to get power back is to turn off traction control via a button. It is back at the dealer now. They have had it the last two weeks. They fixed a shift to park issue but cannot duplicate the loss of power. So they are saying it is ready to pick up. Once, recently, a check engine light come on along with a message saying something like low power mode. We went straight to the dealer with the vehicle. They had the car for three five out of six weeks and were able to duplicate the loss of power once. We wanted them to contact Chevy to help resolve this, but we are unsure if they actually did. These problems first were serviced in April of 2024. This car is very scary to be in, the way this happens and when it is happening.

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.

Where the warnings appear, it keeps saying shift to park. If this continues the car battery will not work.

Brake vacuum pump locked up causing camshaft to twist and reluctant wheel to turn which damaged the engine. I'm being quoted $10,000 to fix which was actually $1,000 more to fix but they accidentally under quoted me and have to honor the original estimate. I don't have that kind of money and still owe almost $14,000 on the car.

There is a message that’s pops up on my dashboard when I cut my car off saying “car not in park” when I have in fact put it in park. I have to jiggle and constantly press the gear shift in order for the message to go away .My safety was fine , I’m just scared that I may not see the message and my car could potentially start rolling backwards or forward. My car has been doing this for about 6-8 months .

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.

Vehicle will say shift to park and also can't use the limp mode and manually shift gears and also can't be used outside of 1st and 2nd gear

When I was in a car accident, the airbag exploded. However, the airbag's balloon-like fabric material did not deploy, and a metal part even flew off the steering wheel and exploded, hitting me in the chin. So I lost about half of my lower jaw, most of my lower teeth, and some of my upper teeth. In the process, I underwent a total of three surgeries: emergency, infection, and reconstruction surgery. In the future, I may need to undergo additional implant surgery and additional reconstructive surgery as needed. There has been no formal component inspection by any agency since the accident and there were no relevant warnings or symptoms prior to the accident.
