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.  .

The brake pedal is hard. The car does not want to stop. The brake booster is not working. The car only has 40,000 miles.
