Frame Rust problems of the 2008 Toyota Sequoia

My vehicle involved in a recall in which there is excessive rust in the frame mainly in states where there is snow and uses salt in roads, michigan is one of these states where I use to live and my car is registered in, however I just relocated to CA few month ago, the dealership and Toyota acknowledge that my vehicle is affected with this recall, however Toyota refuse to do it in the state of California! but if I take my car back to michigan they will do it, its 3000 miles away and not planing to go back please help Toyota case # 1902071493.

Toyota service said the rear sub-frame is rusting and eventually rear wheels could separate from vehicle. This was discovered while Toyota was replacing the main frame under a class action suit. The sub-frame was not included in the suit' therefore Toyota wants me to pay the entire cost of $2550.

Rusty parts (rust extended warranty) the back window on my 2008 Toyota Sequoia fell down abruptly while traveling on the highway. The vehicle was in motion. Items flew from my back window and I was forced to slow down abruptly and prevent drivers in my rear from being in an accident. After pulling over, I had to retrieve those items on a busy roadway. I attempted to diagnose the issue by powering the window back up, but it wouldn't work. I attempted to push the window to the up position and it would not work. I had to secure my items and drive home slowly. Later that day, I conducted some research online and found out the 1st generation Sequoia was issued a recall for the same exact problem. Apparently, the issue was due to a faulty window regulator from rust. Unfortunately, I do not see any recalls for the 2nd generation models. I took my vehicle to a local mechanic and once they examined the back door, they diagnosed that the cause for the window falling down abruptly was indeed from a rusty regulator and rusty parts. I conducted more research and found out that Toyota has been infamous for installing parts that rust over time. Toyota issued an extended warranty for rust, but it doesn't state specifically what it covers. I contacted Toyota and they instructed me to take it into a Toyota dealership. I was told that the rust extended warranty recall pertains only to the undercarriage of the vehicle and not anything else. The notice is the mail did not specify the undercarriage. My rusty parts are not covered under the extended warranty for rust. It is not right that Toyota is finding a way to remove themselves from any liability with their vehicles developing rust over a quick period of time. If a recall was issued for rust on the frame, that's an indicator that Toyota uses poor quality parts.

The 2008 Toyota Sequoia only has 35,300 miles on it and while it was in for oil changed and on the rack, the mechanic noticed a severe rusting issue on the frame. The vehicle has severe rust on the frame in particular the rear axle assembly, including the welds that hold the frame together. I am very concerned with the issue of the roads and stress of potholes that the frame and welds could become severely damaged and possibly break off on the road in particular at high speeds. I have never seen rusting this bad since the automobile industries use of recycled metals. I am concerned because of the use of this vehicle to transport my family.
