2018 Chevrolet Malibu

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 check engine light will come on, a message will pop up on the screen saying, "steering assist reduced drive with care." When i come to a stop and my car goes into auto stop the car will completely shut down. This can be in the middle of the street or during traffic. It will take my car awhile to start back up. I was told it is a sensor that is going bad consistently, this has happened to me 3 times. This is a known issue with a lot of Chevy Malibu.

I WAS DRIVING ON THE INTERSTATE AT 75 MPH AND I WENT TO HIT THE BRAKES AND THEY DIDNT WORK I HAD TO TAKE MY FEET OFF THE GAS AND LET IT STOP ON ITS ON AND IT WAS SCARY. I GLAD TO BE ALIVE. AND WHEN I PUT THE CAR IN PARK IT STATED THE I NEEDED TO SHIFT TO PARK AND I COULDNT CUT THE CAR OFF SO AFTER CALLING SOMEONE TO COME GET ME FROM OFF OF THE SIDE OF THE RIDE. I HAD TO KEEP PUTTING THE GEAR IN PARK FOR IT TO GO IN PARK ANF THE MESSAGE WENT AWAY BUT IT KEEPS COMING ON.

While driving on the highway my dashboard displayed a warning of “reduced power steering “, engine light came off and on, loss of speed , and “stabilitracking” light came on. Brakes also vibrated badly as if they were unable to hold a grip. I was unable to accelerate and was really in danger. The car was taken immediately to the dealership where they replaced the battery and told me it was repaired. On my return from the airport the next morning at 4:30 the same lights and warnings displayed on the dash once again and I had it towed immediately to the dealership. We are now 3 days in and I have gotten no explanation as to what is going on with my vehicle.

I have a 2018 Malibu with a very long list of major issues. The Engine loses power constantly along with a “Engine Reduced Power” warning and check engine light. I get a constant “shift to park” message even after placed in park. All the steering wheel buttons/controls do not work. With the exception of the cruise control. Car almost red lines after the power message displays when you try to increase the speed of the vehicle. The back axle/suspension/hubs make a very loud popping sound when I back up or drive forward. Both back wheel assemblies make a very loud wobble noise when driving. Almost like the assemble is going bad. The Auto Stop/Start causes a lot of issues. It causes the car to jerk horribly and that’s when you hear the popping in the back axles the most. Idk if there is an option to turn this off in this model. But, if there is I can’t access the message center because the steering wheel controls/buttons don’t work. Also upon restart the car runs extremely rough and tries to die. The car has really bad powertrain issues. The car not only loses almost all power….. but, also acts like the transmission is slipping when taking off from a dead stop. Causing it to jerk really bad when the transmission actually catches. The brake system also seems like it has a lot of issues. Here recently the brakes seem like they don’t want to stop the car and that leads to pressing the brake pedal down harder resulting in the brake finally stopping the car in almost a dead stop. This could cause a rear end collision or a collision after your designated stopping point. Every time it rains my trunk gets soaked with water leading to a horrible mildew smell and damaged property in the trunk. Also, the steering wheel will start wobbling uncontrollably when driving down the road and then just stops. It causes a violent shake in the front end until it stops. I’m sure I missed a few things just because of how long the list is. I’m hoping for a solution to these problems.
