NHTSA Complaint #11420146 — 2018 CHEVROLET MALIBU

Several times I have had the engine light come on and a warning of Engine Power Reduced. I have had it checked several times and some it was not able to be diagnosed but others the various modules were replaced - but the issue is not fixed. What is it going to take to have this brought to NHTSA attention as well as GM to get this corrected on a recall? I have almost been hit by 18 wheelers on the freeway due to my car dropping from 75 MPH to 30 MPH and there is nothing you can do when you are on a busy freeway in a construction zone but pray. I have read SEVERAL statements and reports of this happening over and over with other owners. I will definitely loan my car to an investigator at NHTSA or Mary Barra, President of GM, and let them see how safe they feel in a situation when this happens, especially when you have grandchildren or your own children in the car. It has been reoccurring since I purchased the car in 2018 with only 4 miles on the odometer so the information gathered below is only a fraction of the information that is needed. Maybe a selection on the "Was there a crash" and "Was there an injury or fatality?" should be "ALMOST, BU THANK GOD, NO"
