I have just bought out the lease on my SC430 and had to take it in for some general service things and a few items under warranty. The rubber trim around all of the windows has become (extremely) pitted and dry, but that actually happened after the first year of ownership. I am asking JM Lexus in FL (for the 2nd time)to replace it and they have adamantly refused. They're calling it "an environmental issue, not covered under warranty." (Which is probably the most ridiculous excuse I've ever heard!) Pay over 60K for a vehicle and they can't replace the RUBBER!!??? Has anyone out there had this issue come up? Anything I could get a reply on would be extremely helpful, so I appreciate any assistance.
