I also own an 08 GX470. My paint started peeling during warranty but I thought it was from rocks on the interstate or something like that. Got a new windshield and when the tape was removed, large amounts of paint came off stuck to the tape. Took car to reputable paint shop and was told this was a defect. Have tried to get help from Lexus but they refuse to do the right thing. Just like the dashboard deal so I'm waiting and hoping for a class action law suit because that's what it will take. Time is on their side however because cars don't last but I have babied this car because it cost a fortune and I plan to keep it as long as it will roll. The paint is peeling all over and looks horrible but it runs good. This is my last Lexus however due to the peeling paint issue.
