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.

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.

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.

Car demonstrates random full vehicle power loss while in drive mode both at stop and while actually in motion and driving. Vehicle had a catastrophic loss of all break power while going downhill. Luckily while leaving the Lincoln Memorial in DC driver was traveling slow enough and able to get vehicle stopped without immediate injury. Car brakes would not reengage without 3k repair to import/export value(see receipt). 2 days later check engine light returned. 2 weeks later dealer is still in discussion with GM to identify cause of engine failure.
