2018 CHEVROLET MALIBU Complaints

One of my first problems with this car is the “shift to park” error message. This message on the dashboard indicating that my gear is not in P (park) when in fact it is . This error will not allow me to turn off my car even though I am parked. My second issue is just recently I have been experiencing from idle noise and small leakage looks as though it’s coming from the fuel injectors and I was stuck on the road at night because my car decided to stop and the “shift to park” message came back up and my car started to loose acceleration in the middle of the road on a busy street with no stop signs visible. (Car accident waiting to happen). My steering wheel locked up on me and my car completely stopped. I tried to turn it off and back on but this did not work as I tried to mash on the gas with my car in drive . As I did some research I see recalls on my car that I was not aware of which is very accurate to the issue I’m experiencing. Only having this car for one year now and the first issue started way before a year in. Dealership has not fixed my car and the problem has left my car undrivable

ENGINE POWER REDUCED light keeps coming on while driving and the car stalls and won't go over 20mph. Several repairs later and it is still happening almost daily. It has nearly caused an accident several times. This needs to be fixed and a recall for the issue needs to be issued by Chevy. With this many people experiencing this problem, why isn't Chevy obligated to address the issue?

Started car after acceleration, car started shaking , check engine light came on , acceleration decreased and message saying service Stabilitrak. 6 hours later started car and message no longer, check engine light off and car not shaking anymore. Chevy dealership diagnosed misfire, fuel injector needs replaced and damaged ECM.

I repeatedly get a “reduced power to engine” alert on my dash which causes my car to decelerate and I lose my power steering. This last time, the alert popped up on my dash, my car decelerated, and then my brakes would not work. I could not push the brake down to stop my car and ended up in a ditch. My brakes are now hard and I cannot start my car because of it. I have already had the recall for this issue fixed in the past but this will be the 3rd time I have brought my vehicle in for the same problem. I had diagnostic codes ran on my car soon after the accident happened and have attached the pictures to this form.
