2004 Toyota 4Runner SR5 - Frame rust: currently not drivable due to complete breakage from the rust. Driving 2 hours home on the highway I almost lost control, pressing/releasing the brake and/or gas pulls the steering side to side and sways the truck (fish tail) due to damage from the frame rust/breaking. There is no control of the rear end. Truck was in great condition prior to the frame snapping. Vehicle has been inspected by multiple mechanics (including Firestone, Welding/fabricating Auto Repair shops and small owned mechanic shops), possibly won’t be able to weld due to the amount of rust. Firestone won’t perform any service if the vehicle needs to go in the air (tires, oil..etc) due to frame rust. This has been a huge problem with Toyota, they addressed other models around the same year but excluded the 4Runner for unknown reasons. The dealership will not address the issue unless instructed by corporate. This problem jeopardized my safety and the safety of others around wh
