I feel asleep while driving on a residential side street. The vehicle drifted over to the right side of the road and i hit the back end of a u-haul truck. i didn't hear any warning and i don't believe the automatic braking system worked to prevent a collision with such severe damage. I was told the repairs are $16,000.00 roughly. My car has been in the Chevy body shop since the accident in May. They suddenly decided to total the car but donât have additional charges.
