“I own a 2018 Chevy Malibu. At approximately 57,000 miles, the original engine experienced a vacuum pump failure that resulted in catastrophic engine damage. The engine was replaced by General Motors under the vehicle's warranty. I then drove the vehicle for approximately another 52,000 miles with the warranty replacement engine. At that point, I experienced a sudden loss of braking while driving. My vehicle was again diagnosed with a vacuum pump failure, and the vacuum pump was replaced.

I and to replace the water pump as well and all due to this vacuum pump that’s been reported and reported and nothing has been done this is outrageous that what’s caused is so much more then just a vacuum pump it can destroy your vehicle miles don’t matter the less or if you have more the pump goes out when it feels like it. Creating more issues then it should and potentially totaling out a vehicle as it’s been said mine should be. So I’m trying to fix my car to prevent losing it and it’s been one thing after another and such a nightmare. The fact…”
