Gx 470 Manifold

[Masleep]

I have 83,000 miles on my GX470, the vehicle has only been serviced by Lexus. The vehicle was ticking badly when started and accelerating. I was told by Lexus service the manifold had warped, had pin holes in it and the bolts were corroded to the point where they need to be drilled out and re-threaded. I am curious if this might be related to the rust issues associated with Toyota Tundra's, Sequoias and Tacoma's. Anyone else with this issue?
