Brake Hoses, Lines/piping, And Fittings problems of the 2003 Toyota Tacoma

Tl the contact owns a 2003 Toyota Tacoma. While driving 35-40 mph, the front suspension exploded. The front passenger side tire flew underneath the vehicle and the brake line snapped. The vehicle moved onto the side of the road. The dealer and manufacturer were not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 172,661.

So in December I took my Tacoma to the dealership for a regular frame inspection after learning upon the issue. The truck is in almost perfect condition, spotless inside and out. The frame failed inspection, and I was unable to drive the vehicle home. First off, a service rep at the dealership tried to send me off to a friend of his who could "patch" up the frame so that it would pass inspection (great idea, right?). Toyota has provided me with a rental, but the only rental they would give me is a corolla. I live in the mountains, and bought the truck so that I would be able to handle the rough winter weather. I have already had to call out of work as a result of being unable to drive through the snow. I am looking at a date of mid March at the earliest (most likely longer) until I am able to have my truck back, depleting the whole purpose of me having a truck. I have tried getting Toyota to buy the truck back. I love my truck, and I plan on continuing to drive Toyota due to the well-known reliability of these vehicles. I understand that this is a sort of bad luck incident, but considering that rust spreads, I already know that I am going to have to put more money into the vehicle to combat the rust corrosion that has already begun due to a faulty frame. This is obviously already occurring, considering that it is not just the frame that is corroded, but also the brake lines. I am not looking in any way to cheat Toyota, I am just attempting to have a safe vehicle to drive, and I worry that since this corrosion has already started, replacing the frame is only putting off the issue until it becomes noticeable on the rest of the vehicle. If anyone has been able to successfully have Toyota buy back a 2001-2004 model Tacoma, I would love to know how they accomplished this.
