2018 Chevrolet Malibu Driver Assist & ADAS Problems

On July 7, 2023, my Aunt was in a car accident that caused severe injuries to her body, face, and head. Her car is totaled. She believes the car's Lane Keep or Lane Departure systems are the cause of the accident. She has asked me to assist with reporting the accident and wants an investigation done. She received an "Lane Departure" warning about 3 days prior to the accident and again on the morning of the accident when she started the vehicle. She is unsure what the exact message said. When the accident occurred, she states she was vigilant, alert, and focused on driving. She was not on the phone and did not have any other distractions in the car at the time. She was driving on the Hwy when all of a sudden the car jerked her violently out of the lane and into a bridge. The car bounced off the bridge and ended up a ways down the road on the other side. She has a concussion, fractured sternum, fractured sinuses, cuts, bruises, and other injuries. Q. What component or system failed or malfunctioned, and is it available for inspection upon request? A.
