What 191 owners told NHTSA about the 2020 Chevrolet Malibu Eco

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!!!!!!!

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 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.

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.

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.

I bought a 2020 Chevrolet Malibu LT on April 26, 2023 from Lake Hartwell Chevrolet in Toccoa Ga. It drove fine for 3 days. Then a chirping started in the steering wheel. On May 3rd. While I was taking my wife to our baby doctors visit, as I turned into the parking lot, the engine light came on, and the steering failed. I was able to safely get it into the parking lot and out of the way of the other cars. I called the dealership and they had it towed to their shop. They charged the battery saying that's all that was wrong with it. However, as the clean up guy at the shop was bringing it to me, the engine light came on again and he took it back to the shop. Within the next 14 days from then, they replaced the steering module, battery terminals, which seemed burnt, they said, and realigned it. However, all of this is word of mouth as I was not given any paperwork verifying this repair. The next day, the chirp returned. It has very loose steering and sways easily from side to side. Also, upon a diagnostic check by another certified mechanic, the computer would not link and give codes. He told me one of the computers in the car was bad, but not sure which one. I checked and I can not qualify for the lemon law, so I contacted the general manager and said I wanted to return the car and my bank returned their money. Or, another chevrolet car, from Chevrolet, not from this lot. This car is unsafe for me and my family. He said that was not possible as the tag and title has been processed. So I am ready to pursue legal action. The cars they let me drive during my cars repair were junky, too. One wouldn't drive over 30mph and the other had a ticking motor. I feel this business presents a danger to anyone who in need of and buys a car from them. Date of ownership: April 26, '23-present. Today is May 24,'23. They have also failed to give me the paperwork verifying the Chevrolet Lifetime Warranty on the Powertrain and Transmission. That was promised on the day of sale.

While driving on many occasions the last incident happened Friday April 28th 2023. My 2020 Malibu lost all communication on 231 Hwy. All dash gauges went haywire power dropped on vehicle RPM was accelerated but vehicle speed would not change engine light and traction light came on. I then had to pull over brakes made a loud thud noise when stopping. Turned vehicle off sat for about 15 minutes and restarted my vehicle engine light was still on but I was about four miles from home turned my hazard flashers on and made it home. When the car loses power it gives me NO warning at all it just happens. I've taken it to both Chevy dealers in my area Mr. [XXX] at Gilland GMC Ozark, Al explained to me that yes he saw the codes where car lost power and because they couldn't pinpoint the problem GMC had to be called and he was told that GMC has a team of engineers working on the Loss of Control problem but at this time they don't know anything. I'm risking my life on every day driving this vehicle in which I do have an extended warranty on but they can't fix what they can't find but yet KNOW for Fact that there is a problem.

Completely shut down with same warning stating Service battery charging system, once I place car in park it started up and had the battery saver active warning with voltage of 9.2 My car only has 38098 miles. In October it only had 35k. They did replace a fuse on the battery and stated everything was good but I’m confused what keeps making it cut off when it’s brand new car.

My car would completely shut off in the middle of traffics and restart right away. The lights would completely restart, the driver panel, the radio screen, and ESC service light would come on interchangeably with the service engine light. When I would park my car overnight then start it up, the engine won’t start. Then the batter saver mode gets turned on, I’d wait 10 minutes then turn on the car and it works.
