2018 CHEVROLET MALIBU Complaints

I put the car in park and got a message shift to park. I then wasn’t able to shut my car off. The car is only 6 years old! This should not be happening!!!

On Jan 22,2024 while driving on the interstate the speed was unexpectedly instantly reduced, the car would not accelerate over 60 mph and the service engine light came on, the car was safely driven off the highway then towed to the dealership. My safety as well as the safety of other drivers on the highway was at risk when the car suddenly decreased to 60 mph from 75 mph which could have caused a collision. The inspection at the dealership confirmed that the issue was the intercooler for turbo found moisture/oil frozen in charge air cooler causing restriction in induction system, and the part design has been updated to help prevent the issue from happening again. My issue is that if the part has been updated that means that GM is aware of the issue and should be responsible for the cost of the part or there should have been a recall on the part. The consumer should not have to be responsible for the cost of the part or the repair to the vehicle. It is unknown if the part was inspected by an insurance representative but it was inspected by the dealership where the car was purchased. There were no prior warnings, lights or lamps occurring before the date of the incident. I feel like Gm should cover the cost of the repair, the total cost should no fall on the consumer and the vehicle manufacturer should take responsibility for the defective part.

Check Engine Light constantly comes on . Pedal position sensor is faulty. engine power reduced pops up

The car's Reduced Engine Power light comes on and the engine drops power. It just happens at any time while driving. I've had oil changes done, engine cleanings done but nothing changes.

The Vehicle wobbled when at 70 MPH. I have new tires but the wobble won't stop. I have visited a mechanical specialist was refer to this site. Also, the Radio Display touch screen is not working.
