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.

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.

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.

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.

My car had only 600 miles and is brand new. After sitting on the drive overnight the car wouldn't start. There was a lot of clicking noises, but the engine wouldn't turn. That was three weeks ago. I brought it to the dealership and they said that there were error codes on the battery, and that they recharged it. Today, the car clicks and won't turn over again. The car now has 1000 miles. The dealership told me that cars driving by their lot at night will cause random parked new vehicles with no key in it to flash lights, and use other electrical components randomly and it kills the batteries. I think this is a major concern. I park the car regularly in public lots at the airport. I can't have my car battery dead all the time simply because it decides to turn on as other cars drive by.
