2018 Chevrolet Malibu

Check in light is on. They told me it was something with the idle sensor the fixed it. Not even 24 hours later it’s back on they tell me it the vacuum pump & it cost 800 buck. I do some research and noticed on not the only driver with this problem They tell me I can still drive it but nobody told me pieces of the pump could damage the engine also so what do I do now

Vehicle slows way down and loss of power. Engine power reduced. On heads up display. Seems to use alot of gas when this happens. I need to pull over and shut off car. Wait a bit and then restart. And get back on road. It did this 3 times in my commute to work. Also was snowing that morning and was slippery out so very dangerous almost was involved in an accident but luckily not. Seems to do this more in the colder Temps. It has happened however in summer also but not as often. I have read many complaints about this issue. I am not sure why GM has not figured this issue out yet. Very concerned.

MY VEHICLE ACTS AS IF IT DOESNT WANT TO START AFTER BEING AT A RED LIGHT OR STOP SIGN WHEN MY FEET IS RELEASED OFF THE BREAK IT TAKES A FEW SECONDS TO START BACK UP. ALSO I HAVE ISSUES WITH CHECK ENGINE LIGHT COMING ON TOOK IT TO AUTO ZONE AND THEY RECEIVED A CODE DEALING WITH THE WIRING ON THE BATTERY NOT THE ACTUAL BATTERY NEEDING TO BE REPLACED

The second morning in a row my 2018 Chevy Malibu overheated. Early in the morning, the temperature out was about 45-50 degrees, I was driving on the highway about 65-70 mph, I turned on the heater and my cars temperature gage immediately shoots up and the "overheating engine" warning lights start flashing. Confused I pulled over popped the hood there were no signs of smoke or over heating sounds coming from the motor. I got back into the car, turned off the engine, turned it back on, and the temperature gage immediately falls to normal temperature. Happened two mornings in a row now.

Vehicle is constantly telling me to shift to park when the vehicle is clearly in park. Also, the battery will die if this shift to park message isn’t resolved. I’ve already had to replace my battery twice and the dealership keeps telling me they can’t find anything wrong with it. After doing some research I see that this is a VERY common problem for the 2016-2018 Malibu’s and I feel very strongly that it should be recalled.

I always get rattling noise during gas paddle pressed while driving. Once I start put foot on gas paddle, rattling noise starts and when foot remove then it stops. it does not matter what is the speed and whether I am accelerating/de-accelerating. I visited dealer many times to fix this sound issue but not resolved by dealer. I observed another point which is during AC (Heater ON), sound comes but during AC (Cooler ON), rattling sound is infrequent i.e. sometime happens and sometime not. I am not sure from which part this sound comes but it is from Front Hood for sure. This sound I noticed when my car crossed 47K/48K miles in 2020.

Car displayed steering assistance reduced about 2 or 3 times whole driving and I wasn't sure what that meant because it popped up and disappeared so quickly. So a few days later it never appeared again. On this morning as I'm driving and come to a red light to make a left hand turn while waiting and taking my feet off the brake to go cause my light is now green my car turns completely off and I'm stuck at a intersection about 2 to 3 mins later it tells me to start it back up.
