Shift to park warning continues to come on daily when I go to put my car in park. I have to fidget with the shifter to get the computer to recognize that my car is in park and the car will then shut off. Recently I was stopped at a red light, tried to accelerate at the green light and my car completely shut off, while I was still in drive. I could not accelerate and had to place my car in park. Then my stabilitrak sensor came on, along with a notice that my battery saver was on. I had to call a police offer to help me off the road. The car was then able to turn on and I drove it home but this is not safe.

Brake failure, turning into my parents driveway I had to swerve to miss a truck and drove in the yard because of it. It has been diagnosed a faulty brake vacuum pump that caused this failure. I am getting it looked at by a mechanic of Friday and hope that this issue didn't cause further problems with the engine/camshaft. From doing research it seems that many other people have experienced the same issue with the same year vehicle (2017 Chevrolet Malibu). I have also in the past had to get my car fixed by a GM mechanic for the issue of the car giving the "reduced power mode" and basically shutting off while driving down the street. That has now been fixed but was also an issue GM was aware of but I never received a letter or anything about the issue or that there was a recall on it.

When parking car we place the shifter in park, and psh the button to turn off car it states to “Put shifter in Park” after wiggling the shifter that is clearly in park the car will shut off. Also the breaks will pulsate at slower speeds like the ABS is kicking in, but is not the case. Along with the pulsating there are loud thumping noises. Car today when driving did same thing the said “reducing engine power” almost made it home then completely died on me in middle of road. Was told it could be because of bad vacuum pump, brake booster sensor, and brake booster by my mechanic. He said in newer cars this would prevent the car from starting.

Driving down highway slowed down brake assist kicked in for no reason I was stuck in traffic not moving but maybe 2 mph brakes locked up got super hard codes read brake booster and vacuum pump. Screen went black “parking assist off” came on dashboard earlier that morning but nothing seemed to be wrong with the car. Thank God I wasn’t going faster I could have died!

While driving on 12/28/2022, my brakes suddenly became very difficult to apply pressure- almost causing a cramp in my calf because I had to press down so hard. Took the car to a repair shop, only for them to tell me my brake pads are fine. It turns out the problem is with the vacuum pump associated with that part of the car. Looked online to see if this was a common problem and as it turns out, there's a class action lawsuit in litigation about this very issue.
