2018 Ford F-250 SD engine problems

My husband was driving on hwy 77 in va on october 25, 2018 when he accidentally ran into the back of a tri-axle dump truck going at a slower speed. Upon impact something under the hood immediately burst into flames and the fire quickly spread. The side impact air bags did not deflate and my husband struggle to get the driver door open. Fortunately my husband was able to get out of the truck with the help of the dump truck driver pulling on the outside of the truck door.

The contact owns a 2018 Ford F-250. The contact stated that the vehicle failed to start. There was no warning light illuminated before the failure. The contact was unsure if the vehicle was towed or taken to the local dealer, where it was diagnosed and determined that there was rust in the engine. The vehicle was not repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 80,000.
