Service Stabilitrak warning will pop up on my dash. The car loses power. Push on the gas and it sputters. Had it serviced by GMC 2 years ago and now it is happening again. More frequent in colder weather. There are thousands of reddit posts about this same issue from other 2018 Chevy Malibu owners. GMC refuses to acknowledge it is a quality or performance issue on their end.

I was driving the vehicle on a busy road and a message came up on the display above the steering column saying Engine Power Reduced. I went to brake and was unable to push the pedal in as it was extremely stiff. There were vehicles around me and I tried to use both feet and stand on the brakes and was able to get a little bit of movement but the car still didn't slow down. I had my significant other and brother-in-law in the car and we were all horrified we were going to get into an accident. I turned the hazard lights on and was able to steer to avoid hitting several vehicles and when traffic finally cleared I was able to get over and off the road into a gas station that was uphill and allowed us to slow down and finally stop because I put the vehicle in neutral tried the parking brake which got us to a complete stop and shut the vehicle off. There had been no previous issues with the brakes or messages such as the one that came up right before this issue occurred. The vehicle had to be towed and the repair shop told me the cam driven vacuum pump failed which caused the brake booster to not function. When this failure occurred, it damaged the intake and exhaust camshafts, crankshaft, and several other components. The cooling system and oil to be flushed out as I was told there was metal debris from the damaged parts caused by the vacuum pump failure in the fluids which had been all completely flushed and changed including cooling system, transmission fluid, and oil change The total cost of repairs as a result of the vacuum pump failure setting off a Domino effect of damage was $3536.40.

My turbo failed while I was on a very busy highway, causing me from going 70mph to 35mph in a matter of seconds and almost being hit. This put my life and my friends life at risk since we were in the left lane. Now that I’ve been fighting with the dealership ti help make this right they found a GM warranty that fixed and updated electrical sensors. We fixed that first because at the time we thought that was what it was. My turbo gave out again up in the mountains almost killing me and my friend a second time on a busy road. We made it to a parking lot and called a tow truck. Now the stabiltrak is showing up and the car refuses to start, it makes a whooshing sound and doesn’t start completely. (There is fuel, oil, etc). I was sold an unsafe vehicle and now I’m stuck paying 500$ a month for a car that’s unsafe and refuses to work even when it’s been fixed. The dealership is refusing to help me, I’m at a loss. I still owe 18k and I can’t have an in working car sitting in my apartment complex, it will get towed and cost me more money.. I need help. I was sold a car that almost killed me twice and no one seems to care.
