i was steering my MDX 2016 to my garage in slow speed and sudden unintended acceleration caused front right of my car hit a pillar in right. Collision caused damage to front right and the pillar. I am working with insurance to take car to a body shop which is in acura pro first list. car is not in drivable condition. Now how can i fight this out between insurance and Acura or Prove that unintended acceleration caused this.? Kindly suggest what should be my next steps?
